- 2.5 times less insulin than planned
Zones of subcutaneous insulin
- stomach (except midline)
- the upper and outer part of the buttocks
- front-outer part of the thigh
- the outer part of the shoulder
Medium-length insulin needles are long
Information on the syringe pack

- Apply the skin fold method correctly
- select the right angle of the needle
- choose the right needle length
The short needles for insulin syringes are long
What should I look for when testing an insulin vial before placing it on the operating table?
- read the label on the bottle (name, expiration date), check the integrity of the bottle and the date of opening
- make sure that the medicine in the bottle does not change color (insulin takes on a yellow-brown hue under the influence of sunlight)
- ensure that the solution is clear (except NPH- and mixed insulin) and that there are no precipitates
"NPH" in the name of insulin preparations means
- neutral Hagedorn protein
Skin treatment before insulin
- the skin is treated with a cloth moistened with an antiseptic containing alcohol and left to dry completely because alcohol destroys insulin
Preparation of insulin before administration to the patient
- The insulin suspension should be mixed well
- if the insulin has been stored at a low temperature, it should be warmed up
Correct judgment on insulin secretion
- in a healthy person, insulin secretion occurs continuously - this is the basic secretion of insulin
- Consumed food requires additional insulin production, so during food, there is an additional rapid (bolus) release of insulin into the blood - it is stimulated insulin secretion
- the basic secretion of insulin in a healthy person is about 1 IU of insulin per 1 h
- stimulated insulin secretion in a healthy person is approximately 1-2 UNITS for every 10 g of carbohydrates taken with food
Correct judgment on the choice of needle length for subcutaneous insulin administration
- The length of the needle and the route of administration should ensure intradermal administration of insulin
Correct judgment on storage conditions of insulin preparations
- insulin must not be exposed to extremely low or high temperatures
- it is recommended to store open insulin bottles at room temperature (not higher than 25-30 °), not more than 4 weeks
- Insulin stocks in closed bottles are stored in a refrigerator at a temperature of 4-8 ° C
- The shelf life of a closed insulin vial is 30-36 months
Correct assessment of insulin secretion in patients with type 1 diabetes
- Patients with type 1 diabetes need insulin replacement therapy to mimic insulin secretion under physiological conditions
- in patients with type 1 diabetes, the pancreatic beta cells are unable to secrete the required amount of insulin for the body
- Patients with type 1 diabetes have an absolute lack of insulin
Correct assessment of insulin secretion in patients with type 2 diabetes
- In the treatment of patients with type 2 diabetes, drugs that increase the sensitivity of cells to insulin are used
- The concentration of insulin in the blood of patients with diabetes can be normal or even increased
- the cells of the body of patients with type 2 diabetes have reduced insulin sensitivity. They do not respond to normal blood insulin levels.
- Patients with type 2 diabetes have a relative lack of insulin
A true judgment of insulin
- Insulin lowers blood glucose levels
- Insulin is a hormone of a protein nature
- Insulin is produced in the pancreas
Correct assessment of insulin administration
- if insulin enters muscle tissue, it is quickly absorbed, which can lead to the rapid development of severe hypoglycemia
- the effect of prolonged insulin, given intramuscularly, resembles the effect of "short" insulin
Correct judgment on the use of insulin pens with insulin
syringes and pens can only be used by one person and must not be passed on to another person
- if several pens or cartridges are used by several people with a syringe, there is a danger that the biomaterial will enter the cartridge and transfer it to another patient
- the cartridge or pre-filled syringe pens used for daily injections can be stored at room temperature (up to + 30 ° C) in a dark place for 1 month
Correct judgment on the first use of an insulin preparation for the treatment of patients with diabetes
- insulin was first used in a teenager Leonard Thompson, who was suffering from diabetes
- an insulin preparation, first used to treat diabetes, obtained from the canine pancreas
- The first insulin injection for the treatment of patients with diabetes was made by researchers Bunting and Best
- the first insulin injection for the treatment of patients with diabetes was made on January 11, 1922
The correct judgment of the duration of action of insulin that has entered a person's blood
- to prolong the effect of insulin, a neutral protein is added
- Ordinary insulin, as a protein, once in the bloodstream, is rapidly inactivated
Signs of insulin failure
- the insulin, which according to the instructions should be transparent, has become cloudy
- insulin suspension after mixing contains nodules, flakes, nodules
- the solution looks viscous
- the color of the insulin solution (suspension) has changed
Use of long needles for insulin syringes
- used in patients with overweight and normal body weight
- are introduced by the skin fold method
- are entered at an angle of 45 degrees
Use of short needles for insulin syringes
- insert at right angles without the use of skin folds
- Used in lean people and children
Causes of incorrect insulin dosing
- inconsistency of the label indicating the concentration of insulin on the vial and syringe
- introduction of the needle immediately after treating the skin with alcohol, without waiting for it to dry completely
- Insulin leakage from the injection site by rapid removal of the needle
Reasons why you should change the needle every time you use the pen.?
- after use, small amounts of insulin may remain in the lumen of the needle, which may crystallize and clog the needle
- even with one application, the needles become blunt and the silicone coating is erased, so repeated use of the needles results in tissue microtrauma
- there is a risk of infection at the injection site
- when used, air can enter the needle, which will violate the accuracy of dosing if used again
Which drug can be confused with insulin because of the similarity of the bottle design?
Standard error in insulin collection in a syringe with a compartment value of 1 unit
Estimation of the rate of insulin absorption given subcutaneously
- Insulin, injected subcutaneously in the front of the thigh, is absorbed very slowly
- Insulin, which is given subcutaneously in the abdomen, is rapidly absorbed
Typical insulin errors
- unauthorized mixing in a single syringe of different insulin preparations
- incorrect insulin dosing
- intracutaneous or intramuscular administration of insulin
- wrong choice of insulin injection site
Insulin pen storage conditions
- the syringe pen contains thermostable insulin (stable for 30 days), so the patient can store it in the room or carry it in his pocket
Insulin pump device
- a thin flexible tube (infusion system) leaves the insulin reservoir, which is connected by a microelectronic (cannula) inserted into the subcutaneous fat
- Insulin pump contains a vial of insulin
- insulin pump is an electronic device that the patient constantly wears (on the belt, in pockets, in special blankets attached to clothing)
- the insulin pump weighs 65 to 100 g
Characterization of needles used for subcutaneous insulin administration
- Insulin syringe needles have a special three-sided laser sharpening, so they are sharper
- to reduce the traumatic effect, the tip of the needle is coated with silicone grease
- the length and diameter of the needle in insulin syringes are much smaller than in conventional syringes
Characterization of long-acting insulin
- the action of prolonged insulins can last from 12 to 26 hours
- prolonged-acting insulins compensate for insufficient basal insulin secretion
- The criterion for a properly selected dose of prolonged insulin is normal morning glycemia
Characterization of short-acting insulin
- "short" insulins are soluble in water and aqueous solutions of "short" insulins are transparent
- "short" insulins start working half an hour after administration
- short insulins can be given subcutaneously, intravenously, and intramuscularly
- It is recommended to use short insulins 40-50 minutes before meals
What should be prepared and placed on the manipulation table in preparation for subcutaneous insulin administration?
- individual packaging with napkins containing alcohol for the treatment of injection fields, packaging with dry sterile beads
- needle punching needle and class B waste container
- insulin syringe pack
- a bottle of insulin
What can be done to increase the accuracy of insulin dosing?
- select small-syringe syringes (for example, 0.25 or 0.5)
- dilute the insulin solution, making it less concentrated
What do you need to check and clarify when laying on the insulin syringe handling table?
- check that the syringe is designed for insulin with a concentration of 100 PIECES/ml (code U-100). Do not use U-40 insulin syringes!
- specify the division price (should be equal to 1 UNIT or 0.5 UNIT)
- determine the length of the needle
- Check the expiration date of the syringe
What does the inscription "U-100" on the insulin bottle mean?
- the inscription "U-100" indicates the concentration of insulin and means that 1 unit of medicine in the bottle contains 100 units of insulin
Insulin syringe: general characteristics, volume characteristics, and needle size
Like other hormonal drugs, insulin needs a very accurate dose.
Unlike sugar-lowering drugs, this compound cannot be released in tablet form, and the needs of each patient are individual. Therefore, an insulin syringe is used to give the medicine solution subcutaneously, which allows you to inject yourself at the right time.
At the moment, it is quite difficult to imagine that until recently, glass devices were used for injections, which require constant sterilization, with thick needles, at least 2.5 cm long. Such injections are accompanied by intense pain, swelling, and hematomas at the injection site.
In addition, often instead of subcutaneous tissue, insulin invaded muscle tissue, leading to a violation of glycemic balance. Over time, prolonged insulin preparations developed, however, the problem of side effects also remained relevant due to complications associated with the hormone administration process itself.
Some patients prefer to use an insulin pump. It looks like a small portable device that injects insulin subcutaneously throughout the day. The device has the ability to regulate the required amount of insulin. However, an insulin syringe is preferred because of the ability to administer the drug at the time required to the patient and in the right volume to prevent major diabetic disorders.
According to the principle of operation, this device is practically no different from conventional syringes that are constantly used to perform prescribed medical procedures. However, insulin delivery devices have some differences. Their structure also includes a plunger with a rubber seal (hence such a syringe is called a three-component), a needle (disposable or fitted in combination with the syringe itself - integrated), and a cavity with external prescribing compartments.
The main difference is the following:
the plunger moves much softer and smoother, which ensures the absence of pain during the injection and even administration of the drug;
very thin needle, injections are done at least once a day, so it is important to avoid discomfort and serious damage to the epidermal cover;
some models of syringes are reusable.
But one of the main differences is the labels used to indicate the volume of the syringe. The fact is that, unlike many drugs, the calculation of the amount of insulin required to achieve the target glucose concentration is determined not in milliliters or milligrams, but inactive units (UNITS). Solutions of this drug are available in a dose of 40 (with red cap) or 100 units (with orange cap) per 1 ml (denoted by u-40 and u-100, respectively).
The exact amount of insulin required for diabetics is determined by the physician, self-correction by the patient is allowed only if the syringe markings and solution concentration do not match.
Insulin is for subcutaneous use only. If the drug is given intramuscularly, the risk of developing hypoglycemia is high. To avoid such complications, you should choose the right needle size. They are all the same diameter, but vary in length and can be short (0.4 - 0.5 cm), medium (0.6 - 0.8 cm), and long (more than 0.8 cm).
The question of what exactly to focus on depends on the complexity of the person, gender, and age. Roughly speaking, the larger the layer of subcutaneous tissue, the greater the length of the needle. In addition, the method of injection is important. Insulin syringes can be purchased in almost all pharmacies, their choice is wide in specialized clinics for endocrinology.
You can also order the right device online. The latter method of procurement is even more convenient because on the website you can get acquainted in detail with the range of these devices, see their price, and what such a device looks like. However, before buying a syringe at a pharmacy or any other store, you should consult your doctor, and the specialist will also tell you how to properly perform the insulin injection procedure.
Insulin syringe: labeling, rules of use
Externally, a scale with appropriate divisions for accurate insulin dosing is applied to each injection device. As a rule, the interval between two divisions at the same time, the numbers indicate the strips corresponding to 10, 20, 30 units, etc.
It is necessary to pay attention that the printed numbers and longitudinal strips should be large enough. This facilitates the use of a syringe for patients with visual impairment.
In practice, the injections are as follows:
The skin at the injection site is treated with a disinfectant. Doctors recommend injections into the shoulder, upper thigh, or stomach.
Then you need to collect the syringe (or take the syringe pen out of the case and replace the needle with a new one). The device with the integrated needle can be used several times, in which case the needle should be treated with medical alcohol.
Profit solution.
Make an injection. If the insulin syringe is with a short needle, the injection is given at a right angle. If there is a risk of the drug entering the muscle tissue, the injection is given at a 45 ° angle or into the skin fold.
Diabetes mellitus is a serious disease that requires not only medical supervision but also self-monitoring of the patient. A person with a similar diagnosis must inject insulin throughout their life, so they must thoroughly learn how to use the injection device.
First of all, this refers to the peculiarities of insulin dosing. The main amount of medicine is determined by the doctor on duty, it is usually very easy to calculate from the markings on the syringe.
If for some reason there is no device with the right volume and compartment at hand, the amount of drug is calculated by a simple fraction:
By simple calculations, it is clear that 1 ml of insulin solution with a dose of 100 units. can replace 2.5 ml of solution with a concentration of 40 units.
After determining the desired volume, the patient should peel off the cork on the medicine bottle. Then some air is drawn into the insulin syringe (the plunger is lowered to the desired mark on the injector), the needle is punctured with a rubber stopper, and air is released. After that the vial is turned over and the syringe is held with one hand and the medicine container is collected with the other, they get a little more than the required volume of insulin. This is needed to remove excess oxygen from the syringe cavity with a plunger.
Insulin should only be stored in a refrigerator (temperature range 2 to 8 ° C). However, a room-temperature solution is used for subcutaneous administration.
Many patients prefer to use a special pen for syringes. The first such devices appeared in 1985, their use has been shown to people with poor eyesight or limited abilities, who cannot independently measure the required amount of insulin. However, such devices have a number of advantages over conventional syringes, so they are now used everywhere.
The syringe pens are equipped with a disposable needle, a device for its extension, a screen that reflects the remaining units of insulin. Some devices allow you to replace cartridges with the drug in the form of exhausted, others contain up to 60-80 units and are intended for single use. In other words, they should be replaced with new ones when the amount of insulin is less than the required single dose.
The needles in the syringe pen must be changed after each use. Some patients do not do this, which is fraught with complications. The fact is that the tip of the needle is treated with special solutions that make it easier to pierce the skin. After application, the pointed end bends slightly. This is not noticeable to the naked eye but is clearly visible under the lens of the microscope. The deformed needle injures the skin, especially when the syringe is removed, which can cause hematomas and secondary dermatological infections.
The algorithm for performing the injection using a pencil pen is as follows:
Install a sterile new needle.
Check the remaining amount of medication.
A special regulator regulates the desired dose of insulin (a different click has heard each step).
Make an injection.
Thanks to the thin small needle, the injection is painless. The syringe pen allows you to avoid self-dialing. This increases the accuracy of dosing, eliminates the risk of pathogenic flora ..
What are insulin syringes: basic types, principles of choice, cost
There are different types of devices for subcutaneous insulin administration. They all have certain advantages and disadvantages. Therefore, each patient can choose the perfect medicine for themselves.
There are the following varieties, and these are insulin injections:
With removable needle removal. The "plus" of such a device is the possibility of placing the solution with a thick needle and a thin single injection. However, such a syringe has a significant drawback - a small amount of insulin remains in the area of the needle, which is important for patients receiving a small dose of the drug.
With an integrated needle. Such a syringe is suitable for repeated use, however, before each subsequent injection, the needle should be cleaned accordingly. A similar device allows you to measure insulin more accurately.
Syringe pen. This is a modern version of a conventional insulin syringe. Thanks to the built-in cartridge system, you can take the device with you and inject yourself anywhere you need it. The main advantage of the pen is the absence of dependence on the temperature regime of insulin storage, the need to carry a bottle of medicine and a syringe ..
When choosing a syringe, pay attention to the following parameters:
The "step" of division. No problem when the strips are spaced at intervals of 1 or 2 units. According to clinical statistics, the average error in syringe insulin collection is approximately half of the ward. If the patient receives a large dose of insulin, it is not so important. However, with a smaller amount or in childhood, a deviation of 0.5 units can cause a violation of blood glucose levels. It is optimal that the distance between the compartments is 0.25 units.
Making. The divisions should be clearly visible, not erased. Sharpness and smooth penetration into the skin are important for the needle, you should also pay attention to the fact that the plunger slides smoothly in the injector.
Needle size. For use in children with type 1 diabetes, the length of the needle should not exceed 0.4 - 0.5 cm, the rest are suitable for adults.
Aside from the question, what are insulin syringes, many patients are interested in the price of such products?
Conventional foreign-made medical products will cost domestically - at least twice as cheap, but according to many patients, their quality leaves much to be desired. A syringe pen will cost much more - about 2000 rubles. Purchasing with this cartridge should add to these costs.
Pencil needles for injection - description, features, sizes, and cost
Patients with diabetes need a daily intake of insulin. For the convenience of drug administration, special medical devices equipped with various tips have been created. Disposable needles for pen pens vary in length, thickness and price, allowing you to select injectors for individual patient characteristics. When it comes to choosing a device, you need to focus on age, weight, body sensitivity level, and other aspects.
Features of insulin pen needles
People with diabetes practice using disposable insulin needles because repeated use of a single syringe leads to microtrauma of the skin, creating a seal. New thin needle injections are painless. Insulin pen needles are sold separately, inserted at the end of the injector with screws or by clicking.
Device manufacturers for diabetics produce cannulas that cope perfectly with the subcutaneous administration of the drug without affecting muscle tissue. The size of the product varies from 0.4 to 1.27 cm, and the caliber does not exceed 0.23 mm (standard insulin needles have a diameter of 0.33 mm). The thinner and shorter the tip of the pen, the more comfortable the injection.
Insulin needles
Needles appropriate for age, body weight, and preferred route of administration should be selected for insulin therapy. In childhood, injections are made with a short needle 0.4-0.6 cm long. For adults, devices with a parameter of 0.8-1 cm are suitable, for overweight, it is better to inject with conventional insulin syringes. You can buy syringe pen needles at any pharmaceutical store or order from an online pharmacy.
Micro-fine
The products of the legendary medical equipment manufacturer with a century-old history are very popular among patients with diabetes. Micro Fine manufactures different needle diameters compatible with most devices manufactured. The best-selling product of this company is considered to be the following:
model name: Micro Fine Plus database;

cost: 820 r;
characteristics: size 4 mm, thickness 0.23 mm;
pluses: laser sharpening, 100 pieces per package;
shortcomings: not detected.
Lantus Solostar
To introduce the drug, Lantus Solostar developed the eponymous gray syringe pen with a lilac button. After each injection, you must remove the used syringe and close the device with a cap. Install a new sterile tip before the next injection. The following cannulas are compatible with this type of diabetic equipment:
model name: Insupen;
price: 600 r;
features: size 0.6 cm, circumference 0.25 mm;
pluses: three-sided sharpening;
cons: no.
Lantus Solostar solution is contraindicated in early childhood, so longer and thicker needles are suitable for injection. Another type of syringe is used for subcutaneous injections of this type of insulin:

price: 600 r;
Characteristics: Insupen, size 0.8 cm, thickness 0.3 mm;
pluses: threaded thread, minimal injuries during injection;
cons: not found.
NovoFayn
The ultra-thin needles for insulin syringes of this company are combined with all subcutaneous injection systems. Modern production technologies, several hours of sharpening, special spraying prevent skin damage, bruising, and swelling. The following NovoFine needle model is common among adult patients:
model name: 31G;
цена: 699 р.
Features: Set of 100 pieces, size 0.6 cm, disposable;
pluses: electronic polishing, silicone coating;

model name: 30G no. 100;
price: 980 r;
characteristics: size 0.8 cm, width 0.03 cm;
pluses: fast insulin supply;
Disadvantages: age limit.
How to choose needles for insulin pens
When looking for suitable disposable devices, it should be borne in mind that the larger the needle caliber, for example, 31G, the smaller its diameter. When buying a cannula, it is necessary to clarify the compatibility of the product with the used syringe. This information can be read on the packaging. It is important that the drug is injected strictly into the subcutaneous fat, without entering the muscle tissue, which is dangerous for the development of hypoglycemia. Satisfaction with this condition is achieved by an example of the right length of the needle.
Rameema, who is insulin-dependent 40 for two years. Last month I used a Novopen automatic syringe, in which I bought Microfine disposable sterile needles. Unlike standard products, they are thinner, are injected almost painlessly, and there are no traces or cones at the injection site. There is enough packaging for a long time.
Victor, I have been a diabetic for 20 years, since then I have had to try many insulin subjects. Since there is a problem in our clinic with the supply of free syringes, I had to buy them. Novofine tips have reached my injection device. I am very happy with the products of this company, only the set is a bit more expensive.
Natalya, 37, a daughter with diabetes (12 years old), needs to be injected with an insulin preparation every day to feel good. On the advice of our endocrinologist, they started using the Human Luxury injector. Micro Fine thin needles approached her. The child easily makes injections on his own, he does not experience pain or discomfort.
Insulin syringe - device overview, appearance features, price
An insulin syringe is a special device that allows you to give the required doses of insulin quickly, safely, and painlessly. This development is very important because the number of diabetics is constantly growing and people who have insulin-dependent diabetes mellitus are forced to ingest their insulin on a daily basis. The classic syringe is generally not used for this disease because it is not suitable for accurately calculating the required amount of hormone injected. In addition, the needles in the classic device are too long and thick.
Insulin syringe design
Insulin syringes are made of high-quality plastic, which does not react with the drug and is not able to change its chemical structure. The length of the needle is designed so that the hormone is injected precisely into the subcutaneous tissue, not into the muscle. When insulin is injected into a muscle, the duration of action of the drug changes.
The design of the insulin injection syringe repeats the design of its glass or plastic counterpart. It consists of the following parts:
- a needle that is shorter and thinner than in a conventional syringe;
- a cylinder on which scale-shaped markings are placed;
- the piston is housed in a cylinder and has a rubber seal;
- a flange at the end of the cylinder, which is held by injection.
A thin needle reduces damage, thus reducing pain and almost eliminating skin infection. Therefore, the device is safe for everyday use and is designed so that patients can use it independently.
Types of insulin syringes
U-40 and U-100 syringes
There are two types of insulin syringes:
U - 40, calculated on a dose of 40 units of insulin per 1 ml;
U-100 - in 1 ml of 100 units of insulin.
Diabetics usually use only syringes in 100. Very rarely are devices in 40 units used.
For example, if you were cheered on by a hundred - 20 PIECES of insulin, then you need to stab 8 EDs with forts (multiply 40 by 20 and divide by 100). If you take the medicine incorrectly, there is a risk of developing hypoglycemia or hyperglycemia.
For ease of use, each type of device has protective caps in different colors. The U-40 was released with a red cap. The U-100 is made with an orange protective cap.
What are the needles?
Insulin syringes are available in two types of needles:
portable;
integrated, i.e. integrated into the syringe.
Devices with removable needles are equipped with protective caps. They are considered disposable and after use, according to the recommendations, the cap should be placed on the needle and the syringe disposed of.
Needle sizes:
G31 0.25 mm * 6 mm;
G30 0.3 mm * 8 mm;
G29 0.33 mm * 12.7 mm.
Diabetics often use syringes more than once. This poses a health hazard for several reasons:
The integrated or removable needle is not designed for reuse. Blunt, which increases the pain and microtrauma of the skin during the breakthrough.
In diabetes mellitus, the regeneration process can be disrupted, so any microtrauma poses a risk of complications after the injection.
During the use of the device with the removal needles, part of the injected insulin can be retained in the needle, because this less pancreatic hormone enters the body than usual.
After re-use, the syringe needles become dull and painful during the injection.
Labeling features
Each insulin syringe has a printed imprint on the motor housing. The standard division is 1 unit. There are special syringes for children, with a division of 0.5 units.
To find out how many ml of medicine are in a unit of insulin, you need to divide the number of units by 100:
1 unit - 0.01 ml;
20 PIECES - 0.2 ml etc ..
The scale on U-40 is divided into forty divisions. The ratio of each division and dose of the drug is as follows:
1 division is 0.025 ml;
2 divisions - 0.05 ml;
4 compartments indicate a dose of 0.1 ml;
8 compartments - 0.2 ml of hormones;
10 compartments is 0.25 ml;
12 compartments were designed for a dose of 0.3 ml;
20 compartments - 0.5 ml;
40 compartments correspond to 1 ml of the drug.
Injection rules
The insulin delivery algorithm will be as follows:
Remove the protective cap from the bottle.
Take a syringe, pierce the rubber stopper on the bottle.
Flip the syringe bottle.
Holding the bottle upside down, draw the required number of units in excess of 1-2ED into the syringe.
- Lightly touch the cylinder, making sure that all air bubbles come out of it.
- Remove excess air from the cylinder by gently moving the piston.
- Treat the skin at the intended injection site.
- Pierce the skin at a 45-degree angle and slowly inject the medicine.
How to choose a syringe
When choosing a medical device, it is necessary to ensure that the markings on it are clear and vivid, which is especially true for the visually impaired. It must be borne in mind that dose violations with an error of up to half of one division occur very often when recruiting a drug. If you have used a u100 syringe, then do not buy a u40.
For patients who have been prescribed a small dose of insulin, it is best to buy a special device - a pen for syringes with a step of 0.5 units.
The point length of the needle is important when choosing a device. Needles are recommended for children with a length of no more than 0.6 cm, older patients can use needles of other sizes.
The piston in the cylinder should move smoothly, without causing difficulty in injecting the drug. If the diabetic leads an active lifestyle and is active, it is recommended to switch to using an insulin pump or syringe pen.
Syringe pen
The insulin pen device is one of the latest developments. It is equipped with a tank, which greatly facilitates injections for people who lead an active lifestyle and spend a lot of time outside the home.
The handles are divided into:
- disposable, with closed insert;
- reusable, a cartridge in which you can change.
The handles have proven to be a reliable and practical device. They have a number of advantages.
- Automatic regulation of the amount of drug.
- Ability to make multiple injections throughout the day.
- High dosing accuracy.
- The injection takes the least amount of time.
- Painless injection, because the device is equipped with a very thin needle.
- The right dose of medication and diet is the key to a long life of diabetes!
Types and characteristics of insulin syringes
Diabetes therapy includes a series of activities aimed at maintaining the glycemic rate within normal limits.
To achieve this goal, some patients must not only follow a diet but take special medications or subcutaneously give the required amount of insulin to the body. Thanks to special syringes, hormone injections can be performed quickly and painlessly.
What is an insulin syringe?
Insulin therapy requires the use of special medical devices and accessories.
Insulin syringes are most commonly used to administer the drug. They are similar in appearance to the usual medical devices because they include a housing, a special clip, and a needle.
What are the products:
Minus the glass product is the need to regularly count the number of units of the drug, so it is now used less frequently. The plastic option allows injection in the right ratio. The medicine is completely consumed without leaving any residue inside the case. Any of the above syringes can be used several times, provided it is continuously treated with antiseptic and used by one patient.
Plastic products are available in several versions. You can buy them in almost any pharmacy.
Needle volume and length
Insulin syringes can have different volumes, which determines the amount of insulin present and the length of the needle. Each model has a scale and special compartments to help you improve how many milliliters of medicine you can refill in a case.
According to established standards, 1 ml of the drug is 40 units/ml. Such a medical device is marked u40. Some countries use insulin-containing 100 units in each ml of solution. To perform injections through such hormones, you will need to buy special syringes with a u100 incision. Before using the tool, it is necessary to further determine the concentration of the applied drug.
The presence of pain at the time of drug injection depends on the insulin needle selected. The drug comes by subcutaneous injection into adipose tissue. Its accidental entry into the muscles contributes to the development of hypoglycemia, so you need to choose the right needle. Its thickness was chosen to take into account the area on the body where the drug will be applied.
Types of needles depending on length:
short (4-5 mm);
medium (6-8 mm);
long (over 8 mm).
The optimal length is 5-6 mm. The use of needles with these parameters prevents the drug from penetrating the muscles, eliminating the risk of complications.
Types of syringes
The patient may not have medical skills, but at the same time can easily perform drug injections. To do this, it is enough to choose the most favorable version of the product with insulin. The use of a syringe in every respect suitable for the patient makes the injection completely painless, and also allows the necessary control of hormone dosing.
There are several types of tools:
- with a removable needle or integrated;
- syringe pens.
With interchangeable needles
Such devices differ from other similar devices in the ability to remove the nozzle along with the needle at the time of treatment. The piston in the product moves smoothly and gently along the body, reducing the risk of error.
This feature is an important advantage because even a minor dosing error can lead to negative consequences. Needle-change products minimize the risk of complications during insulin therapy.
The most common disposable instruments with a volume of 1 ml and intended for a set of 40-80 units of the drug.
Syringes with an integrated or interchangeable needle are virtually indistinguishable from each other. The only difference between them is that in a product in which there is no possibility of changing the piercing nozzle, a needle floats.
Advantages of the syringe with built-in components:
- safer, because they do not lose drops of the drug and ensure that the patient fully receives the selected dose;
- they do not have a dead zone.
Other characteristics, including sections and scales on the case, are identical to the parameters of other medical devices.
Syringe pen
A medical instrument with an automatic plunger is called a syringe pen. The product can be both plastic and glass. The first option is most common among patients.
housing;
- drug-filled cartridge;
- dispenser;
- protective cap and needle;
- rubber compressor;
- indicator (digital);
- drug entry button;
- cap cap.
Advantages of such devices:
- painlessness with a puncture;
- ease of management;
lack of need to change the drug concentration because special cartridges are used;
- a cartridge with the drug is sufficient for a long period;
- have a detailed dose selection scale;
- It is possible to adjust the depth of penetration.
- the injector cannot be repaired in the event of a malfunction;
- it is difficult to find the right drug cartridge;
- high price.
- departments
Calibration on the product corresponds to the concentration of the drug. Marking on the body means a certain number of medical units. For example, in injections intended for a concentration of u40, 0.5 milliliters corresponds to 20 units.
Use of products with inappropriate labeling may result in incorrectly applied dosage. For the correct choice of hormone volume, a special distinguishing mark is provided. U40 products have a red cap and u100 tools an orange one.
He also has his graduation in insulin pens. Injectors are used with hormones whose concentration is 100 units. The accuracy of dosing depends on the length of the steps between departments: the smaller, the more accurate the amount of insulin will be determined.
How to use it?
You should prepare all tools and a bottle of medicine before performing the procedure.
If necessary, with the simultaneous use of long-acting and short-acting hormones, you should:
Enter air into the medicine container (extended).
Perform a similar procedure using short-acting insulin.
Take the short-acting medicine with a syringe, and then just prolong it.
Rules for giving medicines:
Wipe the medicine bottle with an alcohol swab. If you want to inject a large amount, then you must first shake the insulin to get a homogeneous suspension.
Insert the needle into the vial, then pull the plunger to the desired division.
The solution should fall into the syringe a little more than necessary.
If bubbles appear, shake the solution and expel the air with a plunger.
Wipe the injection area with antiseptic.
Fold the skin over, then inject it.
After each injection, the needles must be changed if they are replaceable.
If the length of the puncture exceeds 8 mm, then the injection must be performed at an angle to avoid entering the muscle.

How to calculate insulin?
To properly administer the drug, it is necessary to be able to calculate its dose. The amount of insulin a patient needs depends on the glycemic index. The dosage cannot be the same constant as it depends on XE (bread units). It is important for the patient to learn to calculate the need for insulin because it is impossible to understand differently how many ml of medicine are needed to compensate for the carbohydrates they ate.
Each division on the injector is the degree of the drug, which corresponds to the specific volume of the solution. If the patient has received 40 PIECES, then, using the solution in 100 pieces, 2.5 units/ml per u100 of the product will need to be administered (100: 40 = 2.5)
How to use a pen?
The use of the syringe pen is as follows:
- Install a new disposable needle to the product.
- Determine the dose of the drug.
- Scroll with the wheel until the desired number appears on the wheel.
- Inject by pressing the button located on the top of the handle (after puncture).
Costs and selection rules
People who are constantly on insulin therapy know how much the materials are needed for its cost.
Estimated cost per piece:
- from 130 rubles for the product u100;
- from 150 rubles for the product u40;
- about 2000 rubles for a pen syringe.
The listed prices only apply to imported devices. The cost of domestic (one-time) is approximately 4-12 rubles.
There are standards to consider when choosing a product for insulin therapy.
That includes:
- The length of the needle depends on the age of the patient. Children are advised to use 5 mm long needles, and adults - up to 12.
- People with obesity should use products that penetrate to a depth of 8 mm.
- Cheap products have lower quality and reliability.
Not all syringe pens can easily find replaceable cartridges, so when buying them you need to find out in advance about the availability of stock for injections.
It is important to understand that the effectiveness of insulin therapy depends on the instrument that the patient chooses for injections.
Hypodermic needle size. The difference between an insulin syringe and a regular one. General consumable specifications
Few people know that if you are prescribed a course of intramuscular injections (even if they are performed by a nurse), it is better not to rely on official materials, but to buy syringes with specific needles at the pharmacy, given your weight, gender, and age. It is clear that thin and short needles are used for children. And for adults? Experts say: it all depends on gender, weight, body. Because women and men have different layers of subcutaneous fat, it is, therefore, necessary to use needles of different lengths by intramuscular injection.
It is important to consider integrity: obese patients need longer needles. Otherwise, a major nuisance can occur: due to the short needle, the drug cannot be injected deep enough and does not enter the muscle, but the subcutaneous fat. Over time, the drug, of course, "dilutes", but, first, the effectiveness of treatment decreases (the drug does not enter the bloodstream quickly), and secondly, at the injection site may form a seal, inflammation, and pain. How to choose the right syringe and needles?
