Easily-assembled high-safety self-destruction injector

Abstract

Disclosed is a self-destructing syringe, comprising an outer casing, a core bar, a piston, a conical head component, a syringe needle and a protecting jacket. The syringe needle is fixed in the conical head component, and the conical head component consists of a threaded conical head, a sealing ring, a transition part and a hollow wedge. The protecting jacket is put around the syringe needle and is movably connected to the needle base of the syringe needle; the conical head component is fixed in the inner cavity at the front end of the outer casing; the piston is installed on the core bar; the main part of the core bar is sheathed inside the outer casing; and the front end of the core bar is inserted into the conical head component and is able to make the syringe needle return inside the outer casing.

Description

technical field [0001] The invention relates to a medical device, in particular to a disposable injector, in particular to a high-safety self-destruction injector which is easy to assemble. Background technique [0002] Disposable sterile syringe is a new type of medical device introduced in my country in the 1980s. It can avoid cross-infection and is easy to use, and is very popular among doctors and patients. However, due to poor management of some medical institutions or profit-driven, single-use syringes are recycled, sold and reused. The repeated use of syringes spreads diseases such as hepatitis B and AIDS. [0003] In recent years, relevant experts pointed out that the risk of occupational infection of medical staff depends on the prevalence of blood-borne diseases in the population. my country is one of the countries with a high incidence of hepatitis B. There are about 120 million carriers of hepatitis B virus, and the infection rate of hepatitis C has reached 1.7%...

Problems solved by technology

[0014] The purpose of the present invention is to solve the existing one-time safety self-destruct syringes, which are inconvenient to manufacture and assemble due to unreasonable structural design, difficult to adapt to large-scale batch production, low pass rate, and potential safety hazards in the self-destruction process. A series of problems, design a high-safety self-destructing syringe with low manufacturing precision, convenient assembly, high degree of automation, and mass production
