Six Precautions for Using Insulin Syringes
Six Precautions for Using Insulin Syringes

Ⅰ. Insulin syringes cannot be matched to the same needle many times

The insulin syringe needle is a disposable product. The diameter of the needle is thin, and the needle is sharp. A thin silicon layer is applied outside to lubricate and reduce friction with the skin. The needle wall is also fragile, reducing the discomfort during injection. From a functional point of view, the needle will bend and deform with burrs or reverse grooves after multiple injections, increasing the resistance when injecting and pulling out the needle and causing damage to local tissues, resulting in injection pain ecchymosis and induration on the skin. From the perspective of safety, repeated use of needles may lead to cross-infection of blood or other infectious diseases, which has a high safety risk. Therefore, the insulin syringe is designed to fix the needle to ensure that the syringe and needle are disposable and not reused.

Ⅱ. Different concentrations of insulin cannot be mixed in the syringe of insulin

When using an insulin syringe and insulin pen, pay attention to distinguish. The insulin concentration in a refill is different from that in a bottle. The insulin in a bottle is about 4ml, and the insulin in a refill is approximately 3ml. In order to avoid the wrong injection dose and prevent hypoglycemia, bottled insulin cannot be put into the refill, and the insulin in the refill cannot be extracted with an ordinary insulin syringe.

Ⅲ. Store insulin properly and pull out the needle of insulin syringe after insulting injection

Insulin is a small molecule protein. The insulin that has not been unpacked needs to be stored in an environment of 2 ~ 8℃. If it exceeds 8℃, the insulin efficiency will be changed. If it is lower than 2℃, the insulin solution will lose biological activity, thus affecting the hypoglycemic effect. In addition, insulin cannot be frozen and shaken excessively, nor can it be directly exposed to the sun. The unpacked insulin shall be stored at room temperature, which shall not exceed 30℃, and whether to put it back into the refrigerator for storage shall be determined according to the instructions. Both ends of the insulin pen needle are needle tips. One can pierce the insulin refill and communicate with the liquid medicine, and the other can be used for subcutaneous injection. Suppose the needle is not pulled out after injection and reused next time. In that case, bacteria will enter the refill through the needle tube, which will pollute the liquid medicine and increase the risk of infection at the injection site.

Ⅳ. Sterile operation of insulin syringe

Because insulin injection is a subcutaneous injection, it is necessary to achieve aseptic operation strictly. Mucous membranes and skin are defense barriers, and there are many microorganisms on the surface. There is also a continuous increase in blood glucose in diabetic patients, suitable for all kinds of bacteria to grow, reproduce and cause or aggravate skin infections. So we must pay attention to disinfection. Wash your hands before injecting insulin with a safety insulin syringe, and then disinfect the injection site with 75% alcohol. Don't wipe it back and forth. Inject insulin after the alcohol is dry.

Ⅴ. Do not inject insulin into the muscle layer when using an insulin syringe

Intramuscular injection of insulin will affect the body's absorption of insulin. Thus the effect of blood glucose control is poor, which is easy to cause blood glucose fluctuation. When using an insulin syringe to inject insulin, the skin can be gently pinched up, deepening the depth of subcutaneous tissue in this part and improving the injection safety.

Ⅵ. Insulin injections can cause hypoglycemia

It should be reminded that insulin injection is prone to hypoglycemia risk. Therefore, patients receiving insulin should carry food to deal with hypoglycemia, such as biscuits, sugar, and drinks. In addition, the used insulin syringe belongs to a sharp medical tool. The used needle needs to be thrown into a special waste container. If there is no particular container, it shall be placed in a covered hard shell container to avoid being pierced by the needle.
