[0002] Diabetes is a chronic disease. When the body's insulin secretion is insufficient and sugar cannot be brought into cells, the sugar will flow through the blood and finally be excreted in the urine through the kidneys, resulting in more sugar in the blood and urine, which is the so-called diabetes. Insulin is a hormone produced by the pancreas that helps the body regulate blood sugar balance. For diabetic patients, injecting insulin is the most effective way to treat diabetes.
[0003] In actual clinical practice, insulin is usually injected through an insulin pen. The insulin pen and the injection needle are separated before use. When in use, the medical staff assembles the injection needle to the insulin pen and injects insulin into the patient; after the injection, the injection needle needs to be removed and thrown into the recycling bin. The current problem is that the injection needle of the insulin pen is very small and sharp. When medical staff remove the injection needle from the insulin pen, they are often pierced by the needle, which brings inconvenience to the work of medical staff and increases the health risks of medical staff.
