Description

Anti-stab insulin injection device

technical field

The disclosure relates to the technical field of medical devices, in particular to a stab-proof insulin injection device.

Background technique

Insulin is a protein hormone secreted by pancreatic β cells in the islets stimulated by endogenous or exogenous substances such as glucose, lactose, ribose, arginine, glucagon, etc. Insulin is the only one in the body that lowers blood sugar hormones. At the same time, it promotes the synthesis of glycogen, fat and protein, and exogenous insulin is mainly used to treat diabetes. Insulin is used to treat most types of diabetes. In general, the need for insulin therapy depends on the degree of insulin deficiency. All patients with type 1 diabetes receive insulin therapy; many patients with type 2 diabetes will need insulin as the beta cell function gradually declines insulin. In the treatment of diabetic patients injecting drugs, diabetic patients or their protectors need to inject insulin 2-3 times a day into the patient's body. At this time, the patient can put the insulin liquid into the refill of the insulin injection pen. , After installing a specific push device, screw on a sterile injection needle before injection, and then through a series of operations, insulin can be accurately injected into the body. However, when the existing insulin pen is in use, the injection needle and the insulin pen are connected by threads. When the insulin needle is in use, medical personnel need to manually remove the insulin needle from the insulin pen. Injury to medical staff, especially after the patient has finished using it, the injection needle carries various germs, exposing the medical staff to the germs, which not only easily causes injury to the medical staff, but also brings a greater psychological burden.

Therefore, the present disclosure provides a stab-proof insulin injection device to solve the problem that the needles of existing insulin pens are easy to stab the medical staff.
