Insulin syringe with needle protection structure

Abstract

The invention discloses an insulin syringe with a needle protection structure, and relates to the technical field of medical instruments. The lower side of the driving frame is screwed with the lower side of the outer ring wall of the medicine storage tube through a hinge, and the upper side of the driving frame is connected with the upper side of the outer ring wall of the medicine storage tube through a hasp; the sealing ring is fixed on the right side wall of the medicine storage pipe and the left side wall of the driving frame; the driving pipe is inserted and fixed on the right side wall of the driving frame; the piston plate is arranged in the driving frame; the push rod is fixed on the right side wall of the piston plate, and the other end of the push rod is arranged in the driving pipe in a penetrating manner; the driving mechanism is arranged on the outer side of the pushing rod; the protective sleeve is fixed on the left side wall of the medicine storage tube and sleeves the outer side of the discharge tube; the protective insertion tube is inserted into the outer peripheral wall of the protective sleeve; the connecting spring is embedded in the peripheral wall of the protective sleeve; the limiting mechanism is embedded in the outer side wall of the protective sleeve, and the needle head can be limited in the injection process, so that the needle head cannot incline, and injection is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an insulin syringe with a needle protection structure. Background technique [0002] Diabetes is a group of metabolic diseases characterized by hyperglycemia. Diabetes is divided into four types according to different pathogenesis, of which the highest incidence is type Ⅰ and type Ⅱ diabetes. Type Ⅰ diabetes is insulin-dependent diabetes. Diabetic patients need to rely on insulin therapy or absolutely depend on exogenous insulin, and must be treated with exogenous insulin. Type 2 diabetes, which was usually called non-insulin-dependent diabetes in the past, also requires exogenous insulin control for long-term patients Most of the blood sugar and insulin injection sites are the abdomen, outer thigh, and outer arm. Most of the injection sites have less distribution of nerves and blood vessels. When injecting, pinch the skin and insert the needle, and the positions of the t...

[0002] Diabetes is a group of metabolic diseases characterized by hyperglycemia. Diabetes is divided into four types according to different pathogenesis, of which the highest incidence is type Ⅰ and type Ⅱ diabetes. Type Ⅰ diabetes is insulin-dependent diabetes. Diabetic patients need to rely on insulin therapy or absolutely depend on exogenous insulin, and must be treated with exogenous insulin. Type 2 diabetes, which was usually called non-insulin-dependent diabetes in the past, also requires exogenous insulin control for long-term patients Most of the blood sugar and insulin injection sites are the abdomen, outer thigh, and outer arm. Most of the injection sites have less distribution of nerves and blood vessels. When injecting, pinch the skin and insert the needle, and the positions of the two injections should be separated. Most of the existing syringes for abdominal injection are intuitive. Observing and distinguishing the two injection positions, it is easy to make errors and mistakes, resulting in hard lumps at the same injection site, and during the injection process, the needle is prone to tilt, so that the injection cannot be performed
