6 steps to using your insulin syringe properly

Insulin injection insulin injectors include traditional syringes, pen insulin syringes, insulin pumps, etc. Here are the correct steps and precautions for using pen insulin syringes for patients:


I. The insulin pen and insulin refill must be used together.


At present, pen type insulin syringes sold in the domestic market are: Novo pen, Youban, Deshi pen. Patients first need to know which manufacturer's insulin pen they use, and then they must use the insulin pen refills from that manufacturer. For example: Novo pens can only use refills of various dosage forms produced by Novo Nordisk. Youcan pens can only use refills of various dosage forms produced by Eli Lilly. The world's first and the only true long-acting basal insulin produced by Nofé-Aventis-it's time to come. Prepare insulin, needles, insulin pens, medical 75% alcohol, and medical cotton swabs before injection.


2, refill liquid, expiration date and installation of refill and needle


Check the properties of the liquid in the refill, depending on whether there are crystals, floc, viscosity increase, and whether it exceeds the expiration date. Needles should in principle be disposable. This new type of needle has a thin diameter and a sharp needle, and at the same time, it is also coated with a thin layer of silicone coating (which reduces friction with the skin and pain during injection). Because of this, the wall of the needle is also very thin, which reduces the strength of the needle and can only meet the requirements of one-time injection. Such as repeated use will cause burrs and barbs on the needle, which will not only increase the pain during injection, but also cause skin bleeding, increase the chance of skin infection, and even the needle may break in the skin. In order to avoid infection, some patients wipe the needle with an alcohol cotton ball. This method not only prevents the infection, but also damages the silicon coating on the needle and increases pain during injection.


Three, exhaust


Put the pen upright, turn the dose selection knob to “1” and then push it to the “0” position to eject a drop of insulin. If no liquid is discharged, repeat this procedure until a drop of insulin is discharged. If medium-effect insulin and pre-mixed insulin are used, the drug should be mixed upside down and vented. The air must be vented each time a new cartridge and needle is installed.


Four, select parts and disinfect



Insulin is commonly injected into the abdomen (5 cm lateral to the navel), the outside of the upper arm, the outside of the middle thigh, and the buttocks.


In order to prevent atrophy or hypertrophy, the injection site should be alternated. For example, after the left upper arm is injected for a period of time, the abdomen or buttocks are injected for another period of time. Attention should be paid to the difference in the speed of insulin absorption in different parts. In order to effectively and smoothly control blood sugar, a single site rotation can be performed, that is, multiple injections are sequenced at the same site over a period of time. At this time, the interval between the two injections should be greater than 2 cm to avoid injection in the spot or induration. After selecting the parts, disinfect with 75% alcohol and dry.


V. Injection


You must check for a sufficient dose of insulin before each injection. If the insulin to be injected is a suspension, the insulin pen should be turned upside down about ten times before the injection can be made when the medicine becomes a uniform white suspension. Long-acting basal insulin comes in a clear solution, which can be injected directly, which brings great convenience to patients. When injecting, gently pick up the skin at the injection site with your left hand, hold the insulin pen directly into the pinched skin, and inject the liquid medicine. After the injection, remove your thumb from the dose knob and leave the needle under the skin. For more than a second, pull out the needle and press the needle eye with a dry cotton swab for more than 3 minutes.


26. Post-injection treatment and preservation of insulin


Put the inner needle cap after the injection, unscrew the needle, discard the discarded needle, and put on the cap.


Generally speaking, unopened insulin refills can be stored at 2 ° C to 8 ° C (in the refrigerator), and refills filled in insulin pens can be stored at room temperature (<25 ° C) for one month after opening. The insulin refill cannot be frozen, and the frozen insulin solution is apt to lose its biological activity. Do not expose the insulin pen to the sun. Generally speaking, the validity period of various insulin pens after they leave the factory is generally 1 to 2 years.
