Insulin pen use needs to stay away from 5 misunderstandings

The insulin pen eliminates the cumbersome process of taking insulin from the insulin bottle by the patient, which can avoid the sputum of the patient injecting insulin in public, and it is convenient for the patient with poor vision or even blindness to inject insulin.

What is an insulin pen?

The insulin pen we often say is similar to the ballpoint pen we usually use. It consists of a pen body, a refill, and a needle. The refill liquid is filled with insulin solution. When using, put the refill into the pen body, then put the needle on it, select the dosage, disinfect the skin, puncture the needle into the skin, and press the button to complete the insulin injection. Because it is easy to use, simple and fast, it has become the first choice for many sugar friends.

Use the insulin pen to avoid five misunderstandings

Insulin pen and refill do not match: Insulin pen matching insulin refill should be selected, such as Novo and pen should be selected Novo and Ling, excellent companion pen should be used to choose Yulin, Dongbao electronic pen should use Gan Shulin.

Insulin refills are not properly preserved: insulin refills that are not opened should be stored in the dark at 2 ° C - 8 ° C. Frozen insulin can not be used. The activated insulin refills are stored in an environment of less than 30 ° C and can be stored for 4 weeks in the dark.

Poor disinfection behavior: poor disinfection behavior, will cause redness, bleeding, bleeding, itching, infection and other adverse conditions at the injection site. The correct disinfection method is to wash your hands before injection, select the injection site, and use an alcohol swab to disinfect the ring from the middle to the circumference. The diameter is about 5 cm. The skin in the disinfection range should not be rubbed repeatedly. Medical swabs and disinfectants should be purchased in small packages and used within the validity period.

Needle re-use: The needle that has been used once has also been damaged. After repeated use, the needle tip may even cause barbs, which may lead to tissue trauma, needle breakage, fat atrophy, and accurate injection dose.

The injection site is not the right choice: short-acting insulin is preferred for the abdomen, medium-acting insulin is preferred for the thigh and buttocks, premixed insulin and the like are preferred for the abdomen before breakfast, and thighs or buttocks are preferred at night.

Note on using insulin pen

Syringes, insulin high-pressure syringes, insulin pumps, and insulin pens are the "four parts" in the history of the development of insulin injection devices. Although the insulin injection pen is not used for a long time, this medical device is specially designed according to the actual needs of diabetic patients. The insulin solution is stored in the refill, the refill is connected to the pen body, and the pen body is a dose-adjusting instrument. The specially designed disposable needle is ultra-fine and ultra-short, and the pain is very light. Here we will talk about the use of insulin pens:

Be prepared

To use insulin pen money, you must first determine the time of insulin injection (usually inject insulin within 30 to 45 minutes before eating). Then, prepare the alcohol cotton ball, needle, insulin pen and insulin, and check if there is enough insulin in the insulin, then check the insulin dosage form. It should be noted that the insulin pen and insulin must be the same manufacturer's products, so as not to match each other. Finally, check the appearance of insulin carefully. Medium or long-acting insulin and 50/50 or 70/30 premixed insulin solutions are uniform suspensions that can be milky when shaken gently. If there is sediment on the bottom of the bottle after shaking gently, or if there is a small block in the liquid, or if a "frost"-like object adheres to the bottle wall, the liquid cannot be used.

Choose the right injection area

Sugar friends should choose the upper arm, abdomen, thigh lateral or arm as a common insulin injection site. Each injection site can be divided into several injection zones, each of which has an area of ​​about 2 square centimeters. Pay attention to the frequent replacement of the injection site, and should not be repeated in one injection zone. Usually, the abdomen is the preferred injection site for insulin injection in diabetic patients. Because the absorption rate of insulin in the abdomen can reach 100%, and the subcutaneous tissue in the abdomen is thick, it is most suitable for self-injection of diabetic patients.

Injection according to the operating procedure

At the time of injection, the patient can gently pinch the skin of the injection site with the left hand, and directly insert the needle into the pinched skin with the right hand holding the insulin pen, and then push the drug solution inward. After the injection is completed, remove the thumb from the dose button, wait for the needle to stay in the skin for 10 seconds, then pull it out, and then press the needle eye with a dry cotton swab for more than 3 minutes. It should be noted that the patient should put the inner needle cap on the needle after the injection of insulin, then unscrew the needle and discard it. Finally, put the cap on the needle, then unscrew the needle and discard it. Finally, put the cap on the insulin pen.

In general, an unopened insulin refill can be stored in an environment of 2 to 8 degrees Celsius (such as a refrigerator in a refrigerator), neither frozen nor exposed to sunlight. The refills that are loaded into the insulin pen after opening can be stored for about 1 month at room temperature (less than 25 degrees Celsius).
