Description

An insulin syringe with needle tip protection function

technical field

The utility model relates to the technical field of syringes, in particular to an insulin syringe with a needle point protection function.

Background technique

Diabetes is a group of metabolic diseases characterized by hyperglycemia. Hyperglycemia is caused by defective insulin secretion or impaired biological action, or both. The long-term high blood sugar in diabetes leads to chronic damage and dysfunction of various tissues, especially the eyes, kidneys, heart, blood vessels, and nerves. At present, diabetes can be controlled well through a variety of treatment methods. For example, patients can control their body by injecting insulin. Insulin is a protein hormone secreted by the islet β cells in the pancreas when stimulated by endogenous or exogenous substances such as glucose, lactose, ribose, arginine, and glucagon. Insulin is the only hormone that lowers blood sugar in the body, and at the same time promotes the synthesis of glycogen, fat, and protein. When diabetic patients use insulin therapy, they need to use a syringe when injecting insulin.

As a preferred technical solution of the present invention, the syringe body is provided with a protective cover on one side of the injection needle, and a rubber stopper is provided inside the protective cover.

Compared with the prior art, the beneficial effects that the utility model can achieve are:

The utility model can support the syringe through the support rod to prevent the injection needle from shifting during the injection process. At the same time, the angle between the support rod and the syringe can be adjusted through the cooperation of the positioning hook and the positioning ring, thereby facilitating the injection of the syringe. Adjust the needle angle and position it after adjusting the needle entry angle to prevent the injection needle from shaking during the injection process.
