Insulin injection can be done with a special insulin syringe or an insulin pen. Both of these tools have the advantages of simple operation, accurate measurement, and thin needles, which are convenient for diabetic patients to operate independently and reduce the pain of patients. Needles, whether special syringes or insulin pens, are single-use items, which means that the needles should be replaced after one injection. Repeated use of needles can dull the needles, increase pain, and may even lead to skin infections.

How to use an insulin syringe correctly? When using these syringes, you should pay attention to cover the needle cap when not in use, do not let the needle come into contact with drugs and other items accidentally on the skin, prevent contamination caused by accidental contact with other items, and avoid skin infection. Since a small amount of insulin remains in a used syringe, one syringe should always be used for one insulin, and used syringes should be stored at room temperature.

Experts remind the majority of patients, "Take the needle for the injection pen as an example, the needle for the insulin pen and the insulin syringe on the market are all designed and manufactured according to the single-use standard. In the insulin injection treatment, the needle for the insulin pen and the insulin should be guaranteed. Syringes are changed one at a time.

Diabetic patients must be cautious when using insulin, and do not use it blindly. Only scientific and correct use can achieve the expected curative effect. At present, only 10% of patients use a new needle for each injection, and more than 30% of patients reuse the needle ten times or more. Repeated use can affect the accuracy of injected insulin doses and cause subcutaneous fat hyperplasia and induration, which can affect insulin absorption and lead to poor glycemic control.
