1 cube in a syringe how many ml. What are the sizes of syringes? Artificial feeding

One cube contains one milliliter, and the number of grams of the drug can be found in the annotation.

One cube is a colloquial designation for one milliliter or one large division on a syringe. One milliliter of water weighs approximately one gram. That is, one cube of the syringe contains one gram of water. Approximately how much will weigh medical preparations based on an aqueous solution, since the content of denser active substances in them is several times less and has practically no effect on the weight of the cube. Even if the packaging indicates an alcohol solution, it should be remembered that this is a very low percentage solution of alcohol and there is still more water in it. So count one cube for one gram and you can't go wrong.

You can find out how many grams of the active ingredient are in one cube (in 1 milliliter) on the package with medicines. In front of me now is a package of diclofenac, where 1 cube contains 25 mg of the active ingredient. Each drug has a different dosage.

1 cube in a syringe is 1 milliliter, and how many grams of the active ingredient is written on the injection box.

One cubic centimeter is called a medicine cube, but the cube holds a different number of grams. Medicines administered by injection have a different ratio of grams and milliliters. To do this, you need to look at the instructions or packaging, it indicates the recommended number of milligrams, and the definition of a cube is used by experienced doctors and nurses.

A cube is a unit of volume equal to one cubic centimeter. A gram is a measure of mass. There are approximately 250 milligrams in one milliliter. And in order to calculate accurately, you need to read about the density information on the package and perform simple arithmetic operations.

Everything will depend on the density of the liquid itself. Still, the chemical composition of each drug is different, the concentration of various components is not equal, so it is impossible to say exactly how many grams are in one cube of grams.

Those. in order to find out the amount of the substance in grams, you must refer to the instructions for the drug / injection liquid. Plus, usually manufacturers indicate in grams separately the active active ingredient (i.e. the main one), and separately the auxiliary components are also in grams.

See the photo above as an example. Data is not written here, as in injections, but the active substance and auxiliary substances are clearly visible in the photo.

If we talk about water, then in one cube there will be 1 ml - volume and 1 mg - weight. But for other liquids, the mass in mg can vary, as it also depends on the density of the substance. But this information must be on the packaging of the medicine.

When they say one cube, they mean one cubic milliliter. If we take for example one cube of water, then its weight will be equal to 1 gram. For drugs, the weight of the cube will depend on their composition. Usually, the packaging indicates how much all the components included in the cubic millimeter of the treatment solution weigh.

Answers

To compare milligrams, milliliters and divisions in a syringe, it is necessary to determine the value of each of these concepts: 1 mg is 0.001 g (thousandth) or 0.kg (millionth); 1 ml. - is 0.001 l. (thousandth), in relation to water and liquids close in density, the equality 1 ml. \u003d 1 g is true. = 1 cc; Divisions of conventional syringes are numbered by the number of milliliters or cc; The divisions between the numbers of a conventional syringe have dashes, the division value of which is 0.2 ml = 20 mg. (with 4 dashes) or 0.25 ml = 25 mg. (with 3 dashes). Accordingly, it is not possible to draw a volume of 1 mg with a conventional syringe, for this you need a pipette or an insulin syringe (the price of 1 division in a 0.3 ml syringe is 0.005 ml, which is equal to 5 mg).

How many ml in 1 syringe cube? How many mg in 1 syringe cube?

1 cube in a syringe is how many ml (milliliters)?

1 cube in a syringe is how many mg (milligram)?

Syringe cubes, slang name for its capacity in ml. One cube in a syringe means one ml. medicinal solution. One ml. water, weighs one gram. So, in one cube, a milliliter of water will be 1000 mg of the weight of this water. The number of mg of the drug substance in the ampoule is determined by the percentage. For example, we have one ampoule of 1% diphenhydramine with a volume of one ml. In dry form, the amount of diphenhydramine in 1 ml, its 1% solution will be 0.01 g. That is, 10 mg.

A cube is the colloquial name for a cubic centimeter, and if we talk about a syringe cube, it is the designation of 1 milliliter (a milliliter is equal to a cubic centimeter).

Thus, 1 cube of a syringe will always equal 1 ml of liquid or drug solution.

There are syringes of different capacities - 1 ml, 2 ml, 5 ml, 10 ml, etc.

Based on the above:

The 1ml syringe is the same as the 1cc syringe.

The 5ml syringe is the same as the 5cc syringe.

The 10ml syringe is the same as the 10cc syringe.

As for the amount of mg (milligram) in the syringe cube, this value will depend on what liquid or medicine is in it.

For example, if you take water, then 1 ml of water \u003d 1 gram of water \u003d 1000 mg of water. That is, 1 cube of a syringe is 1000 mg of water.

In the case of drugs, the amount of mg in 1 ml and in 1 syringe cube will depend on how much active (active) substance is in 1 ml of solution.

This information is usually indicated on the annotations to the medicine.

The drug Gentamicin. On the packaging you can see the following information:

"Solution for intravenous and intramuscular administration 40 mg/ml".

"Solution for intravenous and intramuscular injection 80 mg / 2 ml".

This means that in 1 milliliter there will be 40 mg of the active substance (gentamycin sulfate).

If a single dosage is 100 mg, then for an injection you need to dial 100/40 \u003d 2.5 milliliters or 2.5 syringe cubes.

1 cube is the colloquial name for one cubic centimeter, i.e. this is a unit of volume, and therefore for a liquid or bulk substances this unit will always be the same, no matter what it is: water, sour cream or sand, in the same container there will always be the same volume. A milliliter is also a unit of volume and is equal to just one cubic centimeter. In other words, 1 cube = 1 cubic centimeter = 1 ml. But the weight will depend on the density of the substances, the higher it is, the greater the weight in one unit of volume. For example, 1 ml of water is equal to 1 g, but sunflower oil has a higher density than water, and therefore the weight of 1 ml of oil will be more than 1 g, therefore 1 cube is equal to 1 ml, but the number of milligrams will depend on the density of the substance being measured .

A cube is a kind of slang used in medicine. In fact, there is no such official measure of volume or mass. A cube is one milliliter of a certain solution. That is, when they say that you need to prick a cube with drugs, they talk about one milliliter.

Accordingly, when buying the syringes themselves, they ask how many cubes this manipulation tool is needed for.

As for the mass, nothing can be said for sure here, this parameter will change. Nevertheless, the solutions have different densities, which means that with the same volume they will have a different mass. Yes, and rarely do we see exactly the mass of the injectable drug. Even if we are talking about a powder, we still use a solvent.

A cube is a colloquial designation for one milliliter. That is, 1 cube is 1 milliliter of medicine in liquid form in a syringe.

The number of milligrams per cube is more difficult to translate - it depends on the medicine. Usually, the annotation indicates how many grams of the active substance and auxiliary components are contained in one milliliter of the drug.

Being in the department (regardless of which one - therapeutic, surgical, cardiology, resuscitation), one way or another you have to deal with injections (injections).

Procedural and other nurses most often use this word - a cube (2 cubes, 5, 10 cubes, etc.).

The medical "cube" is a milliliter:

1 cube is 1 ml;

2 cubes is 2 ml;

5 cubes is 5 ml.

For example, to make a cube of analgin - to inject 1 ml of analgin.

As for mg, it (the amount of matter) is determined by the percentage of the substance in the ampoule / vial.

How many units of insulin in 1 ml

Director of the Diabetes Institute: Throw away the meter and test strips. No more Metformin, Diabeton, Siofor, Glucophage and Januvia! Treat him with this. »

Today, the cheapest and most common way to administer insulin to the body is to use disposable syringes.

Due to the fact that less concentrated solutions of the hormone were produced earlier, 1 ml contained 40 units of insulin, so it was possible to find syringes in the pharmacy designed for a concentration of 40 units / ml.

Today, 1 ml of the solution contains 100 units of insulin; appropriate insulin syringes of 100 units/ml are used for its administration.

Since both types of syringes are currently on sale, it is important for diabetics to carefully understand the dosage and be able to correctly calculate the input rate.

Otherwise, with their illiterate use, severe hypoglycemia may occur.

Markup Features

So that diabetics can freely navigate, a graduation is applied to the insulin syringe, which corresponds to the concentration of the hormone in the vial. Moreover, each marking division on the cylinder indicates the number of units, and not milliliters of the solution.

So, if the syringe is designed for a concentration of U40, on the markup, where 0.5 ml is usually indicated, there is an indicator of 20 units, at the level of 1 ml 40 units are indicated.

In this case, one insulin unit is 0.025 ml of the hormone. Thus, the U100 syringe has a reading of 100 units instead of 1 ml, and 50 units at the level of 0.5 ml.

In diabetes, it is important to use an insulin syringe with only the right concentration. For 40 U/ml insulin, a U40 syringe must be purchased, and for 100 U/ml, the appropriate U100 syringe must be used.

What happens if you use the wrong insulin syringe? For example, if a solution is drawn into a U100 syringe from a vial with a concentration of 40 units / ml, instead of the expected 20 units, only 8 units will be obtained, which is more than half the required dosage. Similarly, when using a U40 syringe and a solution of 100 units / ml, instead of the required dose of 20 units, 50 units will be dialed.

In order for diabetics to accurately determine the required amount of insulin, the developers came up with an identification mark that can be used to distinguish one type of insulin syringe from another.

In particular, the U40 syringe, sold today in pharmacies, has a red protective cap, and the U 100 has an orange one.

Insulin syringe pens, which are designed for a concentration of 100 units / ml, have a similar graduation. Therefore, in the event of a device breakdown, it is important to take this feature into account and purchase only U 100 syringes at the pharmacy.

Otherwise, if the wrong choice is made, a severe overdose is possible, which can lead to coma and even death of the patient.

Therefore, it is better to purchase a set of necessary tools in advance, which will always be kept at hand, and warn yourself against danger.

Needle length features

In order not to make a mistake in the dosage, it is also important to choose the right length needles. As you know, they are removable and non-removable type.

Today, insulin needles are produced in lengths of 8 and 12.7 mm. They are not made shorter, as some insulin vials still have thick stoppers.

Also, the needles have a certain thickness, which is indicated by the G symbol with a number. The diameter of the needle determines how painful the insulin will be injected. When using thinner needles, the injection on the skin is practically not felt.

Determining the division value

Today, in a pharmacy, you can buy an insulin syringe, the volume of which is 0.3, 0.5 and 1 ml. You can find out the exact capacity by looking at the back of the package.

Most often, diabetics use 1 ml syringes for insulin therapy, in which a scale of three types can be applied:

Consisting of 40 units;
Consisting of 100 units;
Graduated in milliliters.

In some cases, syringes marked with two scales at once may be sold.

How is the division price determined?

The first step is to find out how much the total volume of the syringe is, these indicators are usually indicated on the package.

In this case, only the intervals are counted. For example, for a U40 syringe the calculation is ¼=0.25 ml, and for a U100 it is 1/10=0.1 ml. If the syringe has millimeter divisions, no calculations are required, since the number placed indicates the volume.

After that, the volume of the small division is determined. To this end, you need to count the number of all small divisions between one large one. Further, the volume of the large division calculated earlier is divided by the number of small ones.

After the calculations are made, you can dial the required amount of insulin.

How to calculate the dosage

The hormone insulin is produced in standard packages and is dosed in biological units of action, which are designated as units. Usually one bottle with a capacity of 5 ml contains 200 units of the hormone. If you make calculations, it turns out that in 1 ml of the solution there are 40 units of the drug.

The introduction of insulin is best done using a special insulin syringe, which indicates divisions in units. When using standard syringes, it is necessary to carefully calculate how many units of the hormone are included in each division.

To do this, you need to be guided that 1 ml contains 40 units, based on this, you need to divide this indicator by the number of divisions.

So, with an indicator of one division of 2 units, the syringe is filled with eight divisions to inject 16 units of insulin to the patient. Similarly, with an indicator of 4 units, four divisions are filled with the hormone.

One vial of insulin is intended for repeated use. The unused solution is stored in the refrigerator on the shelf, while it is important that the medicine does not freeze. When using long-acting insulin, before drawing it into the syringe, the vial is shaken until a homogeneous mixture is obtained.

After removing from the refrigerator, the solution must be warmed to room temperature, holding it for half an hour in the room.

Home > Insulin > Insulin syringe labeling, U-40 and U-100 insulin calculation Insulin syringe labeling, U-40 and U-100 insulin calculation

To calculate insulin and its dosage, it is worth considering that the vials, which are presented on the pharmaceutical markets of Russia and the CIS countries, contain 40 units of insulin per 1 milliliter.

The vial is labeled as U-40 (40 units/ml). Regular insulin syringes used by diabetics are designed specifically for this insulin. Before use, it is necessary to make an appropriate calculation of insulin according to the principle: 0.5 ml of insulin - 20 units, 0.25 ml - 10 units, 1 unit in a syringe for 40 divisions - 0.025 ml. Each line on the insulin syringe marks a certain volume, the graduation for insulin units is a graduation for the volume of the solution, and is calculated for insulin U-40 (Concentration 40 units / ml): 4 units of insulin - 0.1 ml of solution, 6 units of insulin - 0, 15 ml of solution, 40 units of insulin - 1 ml of solution.

In many countries of the world, insulin is used, which contains 100 units in 1 ml of solution (U-100). In this case, it is necessary to use special syringes. Outwardly, they do not differ from U-40 syringes, however, the applied graduation is intended only for calculating insulin concentration U-100. This insulin is 2.5 times higher than the standard concentration (100 U/ml: 40 U/ml = 2.5).

When calculating insulin, the patient must know the dosage established by the doctor remains the same, and is due to the body's need for a specific amount of the hormone. But if a diabetic used insulin U-40, receiving 40 units per day, then when treated with insulin U-100, he will still need 40 units. It's just that these 40 units need to be injected with a U-100 syringe. If you are injecting U-100 insulin with a U-40 syringe, the amount of insulin you inject should be 2.5 times less. For patients with diabetes, when calculating insulin, you must remember the formula: 40 units. U-40 is contained in 1 ml of solution and equals 40 units. insulin U-100 contained in 0.4 ml of solution. The dosage of insulin remains unchanged, only the volume of insulin administered decreases. This difference is taken into account in syringes designed for U-100.

I hope this information will be useful and will make diabetic arithmetic easier for someone. Let's talk in the article about the calculation of the dose of insulin in diabetes.

Insulin is dosed in biological units of action (ED) and released in special vials. So, in one vial with a capacity of 5 ml contains 200 IU of insulin (there is a corresponding marking on the bottle), respectively, in 1 ml - 40 IU of the drug (200:5 = 40). It is better to inject a dose of insulin with a special syringe, on which units are indicated. When using the usual one, before administering the drug, you need to find out how many units of insulin are in each division of the syringe. The calculation is as follows: if 1 ml contains 40 units of insulin dose, this amount is divided by the number of divisions in 1 ml of the syringe and the amount of insulin dose in one division is obtained. For example, in 1 ml of a syringe there are 20 divisions, therefore, in one division there are 2 units (40: 20 = 2). In the case when the patient needs to enter 16 IU, eight divisions of the syringe are filled with medicine. If there are 10 divisions in 1 ml of the syringe, then each division of the syringe corresponds to 4 units of insulin (40: 10 = 4). If it is necessary to enter 16 IU of insulin, four divisions are filled with medicine.

Determining the number of bread units

The main "marker" of the diet for diabetics is carbohydrates. To determine their quantity in products, a conventional unit of calculation is used - a bread unit (XE). Conventionally, it contains 12 g of net carbohydrates and increases blood sugar by 1.7-2.7 mmol / l. To calculate the amount of carbohydrates in XE in the finished product, you need to divide the amount of carbohydrates in 100 g of the product indicated on the original packaging by 12 and you will get the number of bread units for the same 100 g. For example, the package indicates that 100 g of this product contains 60 g carbohydrates. When dividing this number by 12, it turns out that 100 g of this product contains 5 XE.

Glycemic load (GL) is an indicator that reflects the quantity and quality of carbohydrates contained in foods. To calculate it, the formula is used: GL \u003d GI (%): 100 and multiplied by the amount of carbohydrates in grams. Where GI is the glycemic index, which reflects the absorption rate of carbohydrates in the body. It allows you to roughly estimate how blood sugar will increase after consuming a particular product compared to the standard (glucose or white bread). This indicator is expressed as a percentage. For example, GI = 70 indicates that after consuming 50 g of this product, the blood sugar level will be 70% of that which appears after consuming 50 g of pure glucose.

For example, the GI of a boiled potato in its skin is 65%, and 100 g of such potatoes contain 11.5 g of carbohydrates. After eating this amount of potatoes, the glycemic load will be: GL = 65: 100 x 11.5 = 7.5. For comparison, let's determine the same indicator for fried potatoes, the GI of which is 95%, and 100 g of it contains 23.4 g of carbohydrates - GN = 95:100 x 23.4 = 22.2. This formula shows: the more carbohydrates in the product and the higher its GI, the higher the GN indicator, and, consequently, the load on the pancreas increases dramatically. Depending on this, the degrees of GN are distinguished - low (0-10), medium (11-19), high 20 or more (for one serving). The glycemic index of foods is indicated in special tables that every diabetic has.

According to experts, a significant number of people have a predisposition to this disease. You can find out if you have it by answering a simple test.

Do you feel constant, unquenchable thirst?

Do you experience inconvenience due to the frequent urge to urinate, especially when you have to leave home for a long time?

Do dried drops of urine leave thick white spots on the laundry, resembling traces of starch?

Do you suffer from occasional weakness and drowsiness?

Do you notice a deterioration in vision: the contours of objects blur, as if looking through fog?

Are intermittent sensations of numbness and tingling in the palms and soles disturbing?

Are you unable to get rid of acne?

Do you have very dry skin, cuts and scratches do not heal well?

Does itching bother you, especially in the perineum?

In recent months, have you lost 3-5 kg without putting any effort into it?

Constantly experiencing severe hunger, eat and can not get enough?

The more you answered yes, the more likely you are to have diabetes. In this case, you should immediately consult a doctor and take a blood and urine test for sugar.

Diabetes mellitus is a chronic disease in which, as a result of a lack of the pancreatic hormone insulin in the body, disturbances in carbohydrate, fat and protein metabolism occur. Diabetes is treated with diet, sugar-reducing pills, and insulin injections. It is very important for people with diabetes to be able to inject themselves with insulin.

WHAT YOU SHOULD HAVE AT HOME FOR INSULIN INJECTIONS

A special syringe with a capacity of 1 or 2 milliliters (grams) or with graduations in units, several needles (2-3 large ones to collect the medicine, and 3-4 thin ones for its administration), tweezers, cotton wool, alcohol. You should stock up on a sterilizer or select a small pot with a lid.

Before each injection, rinse the disassembled syringe, needles with mandrin (thin wires inserted inside and protecting the needles from contamination) and tweezers, fill with cold boiled water and boil in a closed sterilizer or saucepan for 15 minutes. If syringes and needles are new, then for the first time they are boiled for 40-45 minutes.

HOW MUCH MEDICINES TO TAKE

This must be calculated in advance. Each syringe has a certain number of divisions. You need to know how many units of insulin are contained in each division. The calculation is made as follows: one milliliter contains 40 units of insulin. 40 units are divided by the number of divisions and get the amount of insulin in one division. For example, there are 20 divisions in one milliliter of the syringe, therefore, one division contains 2 units of insulin (40:20). If the patient needs to inject 16 units of insulin, then 8 divisions of the syringe (16:2) should be filled with medicine. Now one-gram syringes are produced, in which there are 10 divisions. Each division corresponds to 4 units of insulin (40:10). If you need to enter 16 units of insulin with such a syringe, it is filled into 4 divisions.

Insulin is available in standard packaging. In a bottle of 5 milliliters of the drug, or 20 units. Thus, one vial is intended for several injections. The remaining medicine, as well as the vials that have not yet been used, should be stored in a dark, cool place, preferably in a refrigerator, on the shelves of the door, preventing the drug from freezing.

If long-acting insulin is used, shake the vial before drawing it into the syringe until a homogeneous mixture is formed.

The drug taken out of the refrigerator should be warmed to room temperature before administration, holding it in the room for about 30 minutes.

HOW TO DRAW MEDICINE INTO A SYRINGE

After sterilizing the syringe, needles and tweezers, the water is carefully drained. While they are cooling, remove the circle from the aluminum cap with which the insulin vial is closed with a knife, wipe the rubber stopper with alcohol, wash your hands with soap and, without turning off the tap with them and without wiping them with a towel, wipe your fingertips with a cotton swab moistened with alcohol. Take the tweezers from the sterilizer and use them to remove and assemble the syringe without touching the plunger, syringe tip and needle with your hands. When the syringe is assembled, put a thick needle on it and remove drops of water with a few piston movements.

The plunger of the syringe is placed slightly above the mark corresponding to the injected dose of insulin. Puncture the rubber cap with a needle and, inserting the needle 1-1.5 cm deep, squeeze out the air in the syringe into the vial. Then turn it with the needle up (the vial is above the needle) and draw insulin 1-2 divisions more than the required dose. Pull the needle out of the rubber cap, and then remove it from the syringe; put a thin needle on the syringe with tweezers, removing the mandrin from it. Slightly press the plunger to remove air from the syringe, and let one or two drops of medicine drain from the needle tip (these are the very extra 1-2 divisions). Now you can inject.

HOW TO ENTER INSULIN

Insulin is injected subcutaneously into the outer surface of the shoulder, thighs, buttocks, the central abdomen and under the shoulder blades. It is more convenient to inject insulin into the thigh yourself.

Wipe the injection site with alcohol. With the thumb and forefinger of the left hand, gather the skin into a thick fold and pierce it with a sweep almost parallel to the surface. The needle should enter the skin by 1-1.5 centimeters. After that, dissolve the fold and slowly press the piston with your index finger or thumb.

Make sure that insulin does not leak from the syringe. The dose of the administered medicine must be very precise.

When the piston has entered the syringe all the way and there is no medicine left in it, attach a piece of cotton wool moistened with alcohol to the injection site and slowly remove the needle. It is not necessary to massage the resulting swelling, so as not to accelerate the flow of insulin into the blood. You should also not inject into the same place.

When leaving on vacation or on a business trip, you can use the case with alcohol to keep the syringe and needle in a sterile condition. Before injection, it is necessary to carefully remove the remnants of alcohol from the syringe and needle, since alcohol, once in insulin, will weaken its effect.

Syringe marking

So that patients do not get confused, for them, the manufacturer puts a special graduation on the syringe, which indicates the concentration of insulin in the medicine vial. It is worth noting that each risk on the cylinder does not at all mean milliliters of the solution, it indicates the number of units.

Marking division features:

When a syringe is needed for a U40 concentrate, on the marking division, where, as a rule, 0.5 ml is written, an indicator of 20 units is observed, and 40 units are written at the 1 ml level.
With all this, 1 insulin unit is equal to 0.025 ml of insulin.
The U100 syringe has a parameter of 100 units, not 1 ml, and 50 units is 0.5 ml.

Diabetes mellitus involves the use of an insulin syringe of the required concentration. If the patient uses the hormone 40 units / ml, then U40 is mandatory, and when 100 units / ml, then U100.

Many patients wonder what will happen if they make a mistake and use the wrong syringe? For example, when a liquid with a concentration of 40 units / ml is collected in U100, instead of the required 20 units, only 8 units will be obtained. That is, the dosage will come out two times less than what is needed in this situation.

Another analogue can be given when U40 and a solution of 100 units / ml are used, but in reality only 50 units will be obtained, but 20 are needed.

In order for a diabetic to easily select the necessary insulin syringe, manufacturers have come up with a specific identification mark to help select the required syringe:

The syringe of 40 units has a protective cap with a red tint.
The 100 unit syringe has an orange cap.

Similarly, insulin pens can be distinguished, which are calculated for 100 units. In this regard, if for some reason a breakdown or loss of the pen occurs, it is important to know how much volume is in the syringe or in the insulin pen, and how to distinguish them.

In situations where the patient purchased the wrong product, an overdose of insulin is not ruled out, which can lead to serious consequences, and even death.

How to choose a needle and determine the division price?

Patients are faced with the task of not only choosing the correct volume of the syringe, but also choosing a needle of the required length. The pharmacy sells two types of needles:

Medical experts advise opting for the second option, because removable needles have the peculiarity of retaining a certain amount of a medicinal substance, the volume of which can be up to 7 units.

To date, needles are produced, the length of which is 8 and 12.7 millimeters. They are not produced less than this length, because medicine bottles with thick rubber stoppers are still sold.

In addition, the thickness of the needle is of no small importance. The fact is that when insulin is injected with a thick needle, the patient will feel pain. And using the thinnest possible needle, the injection is absolutely not felt by the diabetic. In the pharmacy you can buy syringes with different volumes:

In the vast majority of cases, patients prefer to opt for 1 ml, which is labeled with three types:

In some situations, you can purchase an insulin syringe with a dual designation. Before injecting yourself with medicine, you need to determine the entire volume of the syringe. To do this, you must do the following:

First, the volume of the 1st division is calculated.
Further, the entire volume (indicated on the package) is divided by the number of divisions in the product.
Important: you need to count only intervals.
Then you need to determine the volume of one division: all small divisions are counted among all large ones.
Then, that volume of the big division is divided by the number of small divisions.

How is the dose of insulin calculated?

It was found out how much the volume of the syringe is, and when to choose a syringe for U40 or U100, you need to know how to calculate the dose of the hormone.

The hormonal solution is sold in packaging made according to medical standards, the dosage is indicated by means of BID (biological units of action), which have the designation "unit".

Typically, a 5 ml vial contains 200 units of insulin. When recalculated in another way, it turns out that 1 ml of liquid has 40 units of the drug.

Features of the introduction of dosage:

It is desirable to do the injection with a special syringe, which has single divisions.
If a standard syringe is used, then before dosing, you need to calculate the number of units included in each of the divisions.

The medicine bottle can be used many times. The medicine must be stored in a cold place, but not in the cold.

When a hormone with a prolonged property is used, the vial must be shaken before drawing up the medicine in order to obtain a homogeneous mixture. Before administration, the drug must be warmed to room temperature.

In summing up, it is necessary to summarize that every diabetic should know what the marking of the syringe means, which needle to choose correctly, and how to calculate the correct dosage. Exclusively this knowledge will help to avoid negative consequences and preserve the health of the patient.

Syringe - syringe discord

Doctors around the world began to use a special syringe for insulin injection several decades ago. Several variants of syringe models for diabetics have been developed, which are easy to use on their own, for example, a pen or a pump. But outdated models have not lost their relevance.

The main advantages of the insulin model include simplicity of design and availability.

The insulin syringe should be such that the patient can painlessly inject himself at any time, with minimal complications. To do this, you need to choose the right model.

What does pharmacology offer?

In pharmacy chains, syringes of various modifications are presented. By design, they are of two types:

Disposable sterile, in which the needles are replaceable.
Syringes with a built-in (integrated) needle. The model does not have a "dead zone", so there is no drug loss.

Which species is better is difficult to answer. Modern syringe pens or pumps can be carried with you to work or school. The drug in them is filled in advance, and remains sterile until use. They are comfortable and small in size.

Expensive models are equipped with electronic mechanisms that will remind you when it is necessary to give an injection, show how much medication has been injected and the time of the last injection. Similar ones are shown in the photo.

Choosing the right syringe

The correct insulin syringe has transparent walls so that the patient can see how much medicine has been taken and injected. The piston is rubberized and the drug is injected smoothly and slowly.

When choosing a model for injection, it is important to understand the divisions of the scale. The number of divisions on different models may vary. One division contains the minimum amount of drug that can be drawn into a syringe

Why is a division scale necessary?

On the insulin syringe, there must be painted divisions and a scale, if they are not, then we do not recommend purchasing such models. The divisions and the scale show the patient how much concentrated insulin is inside. Standardly, this 1 ml of the drug is equal to 100 units, but there are expensive devices for 40 ml / 100 units.

For any model of an insulin syringe, divisions have a small error, which is exactly ½ division of the total volume.

For example, if a drug is administered with a 2-unit syringe, the total dosage will be +- 0.5 units of the drug. For the reader's information, 0.5 units of insulin can lower blood sugar by 4.2 mmol/L. In a small child, this figure is even higher.

This information should be understood by any diabetic patient. A small error, even 0.25 units, can lead to glycemia. The smaller the error in the model, the easier and safer it is to use the syringe. This is important to understand so that the patient can accurately administer the insulin dose on their own.

To administer the drug as accurately as possible, follow the rules:

the smaller the division step, the more accurate the dosage of the administered drug will be;
before the introduction of the hormone is better to dilute.

A standard insulin syringe is a capacity of no more than 10 units for the administration of the drug. The division step is marked with the following numbers:

Insulin labeling

On the market in our country and the CIS, the hormone is produced in vials with a solution of 40 units of the drug per 1 ml. It is marked U-40. Standard disposable syringes are designed for this volume. Calculate how many ml in Unit. division is not difficult, since 1 Unit. 40 divisions equals 0.025 ml of the drug. Our readers can use the table:

Now let's figure out how to calculate a solution with a concentration of 40 units / ml. Knowing how many ml in one scale, you can calculate how many units of the hormone are obtained in 1 ml. For the convenience of readers, we present the result, for marking U-40, in the form of a table:

Abroad, there is insulin labeled U-100. The solution contains 100 units. hormone per 1 ml. Our standard syringes are not suitable for this medicine. Need special. Their design is the same as the U-40, but the division scale is designed for the U-100. The concentration of imported insulin is 2.5 times higher than our U-40. You need to calculate based on this figure.

How to use an insulin syringe correctly

We recommend using syringes for hormonal injections, the needles of which are not removable. They do not have a dead zone and the drug will be administered in a more accurate dosage. The only drawback is that after 4-5 times the needles will become blunt. Syringes with removable needles are more hygienic, but the needle is thicker.

It is more practical to alternate: at home, use a disposable simple syringe, and at work or elsewhere, a reusable one with a non-removable needle.

Before drawing the hormone into the syringe, the vial must be wiped with alcohol. For short-term administration of a small dose, it is not necessary to shake the medication. A large dosage is available in the form of a suspension, so shake the vial before tying.

The plunger on the syringe is pulled to the required division and the needle is inserted into the vial. Air is forced inside the bubble, the piston and the medicine under pressure inside, is drawn into the device. The amount of medication in the syringe should slightly exceed the administered dose. If air bubbles get inside, then lightly tap on it with your finger.

It is correct to use different needles for drug collection and injection. For a set of medication, you can use needles from a simple syringe. You can only inject with an insulin needle.

There are a number of rules that will tell the patient how to properly mix the drug:

short-acting insulin should be drawn into the syringe first, then long-acting;
short-acting insulin or NPH should be used immediately after mixing or stored for no longer than 3 hours.
Do not mix intermediate-acting insulin (NPH) with long-acting suspension. Zinc filler converts a long hormone into a short one. And it's life-threatening!
Detemir and long-acting insulin Glargine should not be mixed with each other and with other types of hormones.

The place where the injection will be given is wiped with a solution of an antiseptic liquid or a simple detergent composition. We do not recommend using an alcohol solution, the fact is that in patients with diabetes, the skin dries. Alcohol will dry it out even more, painful cracks will appear.

Insulin must be injected under the skin, not into muscle tissue. The puncture of the needle is done strictly at an angle of degrees, shallow. Pulling out the needle after the injection of the drug is not worth it, wait 10-15 seconds for the hormone to be distributed under the skin. Otherwise, the hormone will partially come out into the hole from under the needle.

General calculation rules

An important rule in the algorithm for calculating the dose of insulin is the patient's need for no more than 1 unit of the hormone for every kilogram of weight. If you ignore this rule, then there will be an overdose of insulin, which can lead to a critical condition - hypoglycemic coma. But for the exact selection of the dose of insulin, it is necessary to take into account the degree of compensation for the disease:

In the early stages of type 1 disease, the required dose of insulin is selected at the rate of no more than 0.5 units of the hormone per kilogram of weight.
If type 1 diabetes is well compensated for a year, then the maximum dose of insulin will be 0.6 units of the hormone per kilogram of body weight.
In severe type 1 diabetes and constant fluctuations in blood glucose levels, up to 0.7 units of the hormone per kilogram of weight are required.
In the case of decompensated diabetes, the dose of insulin will be 0.8 U/kg;
With gestational diabetes mellitus - 1.0 U / kg.

So, the calculation of the dose of insulin occurs according to the following algorithm: Daily dose of insulin (ED) * Total body weight / 2.

Example: If the daily dose of insulin is 0.5 units, then it must be multiplied by body weight, for example 70 kg. 0.5 * 70 \u003d 35. The resulting number 35 must be divided by 2. You get the number 17.5, which must be rounded down, that is, you get 17. It turns out that the morning dose of insulin will be 10 units, and the evening - 7.

What dose of insulin is needed for 1 bread unit

A grain unit is a concept that was introduced in order to make it easier to calculate the dose of insulin administered immediately before a meal. Here, not all products that contain carbohydrates are taken into account in the calculation of bread units, but only “countable” ones:

In Russia, one bread unit corresponds to 10 grams of carbohydrates. It equates to one bread unit a slice of white bread, one medium-sized apple, two teaspoons of sugar. If one bread unit enters an organism that is unable to produce insulin on its own, then the level of glycemia increases in the range from 1.6 to 2.2 mmol / l. That is, these are exactly the indicators by which glycemia decreases if one unit of insulin is injected.

From this it follows that for each accepted bread unit, it is required to pre-administer about 1 unit of insulin. That is why, it is recommended that all diabetics acquire a table of bread units in order to make the most accurate calculations. In addition, before each injection, it is necessary to control glycemia, that is, to find out the level of sugar in the blood using a glucometer.

If the patient has hyperglycemia, that is, high sugar, it is necessary to add the required number of units of the hormone to the appropriate number of bread units. With hypoglycemia, the dose of the hormone will be less.

Example: If a diabetic has a sugar level of 7 mmol / l half an hour before a meal, and he plans to eat 5 XE, he needs to inject one unit of short-acting insulin. Then the initial blood sugar will decrease from 7 mmol / l to 5 mmol / l. Also, in order to compensate for 5 bread units, it is necessary to introduce 5 units of the hormone, the total dose of insulin is 6 units.

How to choose the dose of insulin in the syringe?

To fill a regular syringe with a volume of 1.0-2.0 ml with the right amount of medicine, it is necessary to calculate the division price of the syringe. To do this, you need to determine the number of divisions in 1 ml of the instrument. The hormone of domestic production is sold in bottles of 5.0 ml. 1 ml is 40 units of the hormone. 40 units of the hormone must be divided by the number that will be obtained by counting the divisions in 1 ml of the instrument.

Example: There are 10 divisions in a 1 ml syringe. 40:10 = 4 units. That is, 4 units of insulin are placed in one division of the syringe. The dose of insulin to be injected should be divided by the price of one division, so you get the number of divisions on the syringe that must be filled with insulin.

There are also syringe pens that contain a special flask filled with a hormone. When you press or turn the button on the syringe, insulin is injected subcutaneously. Until the moment of injection, it is necessary to set the desired dose in syringe pens, which will enter the patient's body.

How to administer insulin: general rules

The introduction of insulin takes place according to the following algorithm (when the required amount of medication has already been calculated):

Hands should be disinfected, put on medical gloves.
Roll the medicine bottle in your hands so that it is evenly mixed, disinfect the lid and cork.
Draw air into the syringe in the amount in which the hormone will be injected.
Put the bottle of medicine vertically on the table, remove the cap from the needle and insert it into the bottle through the cork.
Press the syringe so that air from it enters the vial.
Turn the bottle upside down and draw into the syringe 2-4 units more than the dose that should enter the body.
Remove the needle from the vial, release the air from the syringe, adjusting the dose to the required.
The place where the injection will be made should be disinfected twice with a piece of cotton wool and an antiseptic.
Inject insulin subcutaneously (with a large dose of the hormone, the injection is done intramuscularly).
Treat the injection site and the instruments used.

For rapid absorption of the hormone (if the injection is subcutaneous), it is recommended to inject into the abdomen. If the injection is given in the thigh, the absorption will be slow and incomplete. An injection in the buttocks, the shoulder has an average suction rate.

Extended insulin and its dose (video)

Long-term insulin is prescribed to patients to maintain normal fasting blood glucose levels so that the liver has the opportunity to produce glucose constantly (and this is necessary for the brain to work), because with diabetes the body cannot do it on its own.

Extended insulin is administered once every 12 or 24 hours, depending on the type of insulin (today, two effective types of insulin are used - Levemir and Lantus). How to correctly calculate the required dose of prolonged insulin, says in the video a specialist in diabetes control:

Knowing how to correctly calculate insulin doses is a skill that every insulin-dependent diabetic should master. If you choose the wrong dose of insulin, then an overdose can occur, which, if not provided in time, can be fatal. Proper doses of insulin are essential for a diabetic's well-being.

One cube in a syringe means one ml. medicinal solution. One ml. water, weighs one gram. So, in one cube, a milliliter of water will be 1000 mg of the weight of this water. The number of mg of the drug substance in the ampoule is determined by the percentage. For example, we have one ampoule of 1% diphenhydramine with a volume of one ml. In dry form, the amount of diphenhydramine in 1 ml, its 1% solution will be 0.01 g. That is, 10 mg.
