Harm of repeated use of insulin needle in diabetic patients

Can insulin needles be reused? With the increase of diabetic patients, more and more patients use insulin. Because insulin injection is usually a long-term treatment process, many patients often reuse disposable insulin with needles in order to save money, which leads to local infection and ulceration for a long time. The cost of hospitalization far exceeds the cost of buying needles. Therefore, this will not only save money, but also increase the physical pain of patients.

What are the hazards of reusing disposable insulin needles?

1. Increase injection pain. Long-term use of the needle will cause hook bending that is not easy to be found by the naked eye, leading to bleeding and abrasion at the injection site, which will aggravate the pain of patients during injection. At the same time, needles are usually disinfected with alcohol when they are reused, but alcohol wiping will destroy the silicified layer on the surface of needles and increase the pain of injection. The needle of the insulin injection pen is a disposable sterile injection needle, which does not need disinfection before use.

2. The chance of broken needle increases. Repeated use may cause the needle tip to break in the human body, resulting in serious consequences.

3. The chance of infection has increased. Repeatedly, users usually don't pull out the needle after injection, which establishes an open channel between the refill and the outside, thus allowing bacteria to enter the refill through the needle tube, polluting the liquid medicine and increasing the chance of infection at the injection site.

The needle is blocked. The residual insulin in the used syringe will form crystals and lead to blockage.

5. Hyperplasia of subcutaneous adipose tissue. Failure to rotate the injection site correctly or reuse the needle will lead to hyperplasia of subcutaneous adipose tissue, which will not only cause unstable insulin absorption, but also make blood sugar unable to be controlled smoothly and effectively. At the same time, the required insulin dosage is also increasing, which will also affect the appearance and image of individuals, increase mental stress, and is not conducive to the control of diabetes.

6. The supplementary liquid is leaking. Repeat, users usually don't remove the needle after injection. When the temperature rises, the volume of insulin expands and leaks from the refill, thus wasting insulin and changing the concentration of premixed insulin.

7. Air enters the refill. When the temperature decreases, the volume contraction of insulin causes air to enter the refill, resulting in bubbles, which affects the accuracy of injection dosage.
