There are tips for using insulin pens

Although insulin syringes have gone through "four steps" of development and have made significant progress in convenience and accuracy, patients still have to worry about when injecting insulin. There are several points that require special attention:

First of all, preparations must be made before the injection:

1. Determine the meal time and ensure that you eat within 30-45 minutes after the injection.

2. Prepare alcohol cotton balls, needles, insulin pens and insulin. Note that the insulin pen and insulin must be products from the same manufacturer to avoid mismatch.

3. Check the insulin dosage form again.

4. Check the appearance of the insulin carefully. Intermediate-acting and long-acting insulin or premixed 50/50 and 70/30 insulin are suspensions with a uniform appearance. After gentle shaking, they look like milk. If there is sediment at the bottom of the bottle after gentle shaking, small lumpy objects are precipitated or suspended in the liquid, or a layer of "frost"-like objects adheres to the bottle wall, it cannot be used.

Then, choose a suitable injection area: Commonly used insulin injection sites include the outside of the upper arm, abdomen, outside of the thigh, and buttocks. An injection area is 2 square centimeters, and each injection site can be divided into several injection areas. The injection area means that each injection should be in one area. The injection site should be rotated each time and should not be injected several times in one injection area. The abdomen is the preferred site for insulin injection. The insulin absorption rate in the abdomen can reach 100. The absorption rate is faster and the subcutaneous tissue is thicker, which can reduce the risk of injecting into the muscle layer and is the easiest to self-inject.

Next, comes the injection: a sufficient dose of insulin must be checked before each injection. When injecting, gently pinch the skin at the injection site with your left hand. Hold the insulin pen in your right hand and insert the needle directly into the pinched skin. Inject the medicine. After the injection, remove your thumb from the dosage knob and keep the needle under the skin for 10 seconds. for more than seconds, then pull out the needle and press the eye of the needle with a dry cotton swab for more than 3 minutes.

After the injection, the inner needle cap should be put on, the needle should be unscrewed, the discarded needle should be discarded, and the pen cap should be put back on. At the same time, attention should be paid to the storage of insulin. Generally speaking, unopened insulin refills can be stored in an environment of 2℃-8℃ (in the refrigerator). The refills loaded into the insulin pen after opening should be stored at room temperature (
