Abstract

The invention relates to a safety syringe whose needle retracts and deflects and automatically destroys. In order to provide a syringe with simple structure, low cost, complete damage to the needle, and the phenomenon of preventing the syringe from polluting the environment, the present invention is proposed. It consists of a syringe, a needle group and a piston group. The two ends of the syringe are respectively It is a needle cylinder body and a neck tube; the needle head group is composed of a hollow needle body and a needle handle, and the bottom end of the through hole in the center of the needle handle forms a tapered recess and a bell mouth with a center line deviation; the needle body is fixedly installed in the center of the needle handle. On the hole; the piston group is composed of a piston and a piston rod, and an arrow body is arranged on the piston, and the center line of the arrow body is located on the center line of the neck tube of the syringe.

Description

technical field [0001] The invention belongs to a device for injecting a medium into the body, in particular to a safety syringe with a retracted and deflected needle that is automatically destroyed. Background technique [0002] With the improvement of people's awareness of environmental protection, disposable syringes are usually used and the needles are destroyed before being discarded. However, such conventional disposable syringes not only have complex structures and high costs, but also do not completely damage the needles. , there is still a major hidden danger of polluting the environment. Contents of the invention [0003] The purpose of the present invention is to provide a safety syringe with simple structure, low cost, complete damage to the needle head, and can prevent the phenomenon of the syringe from polluting the environment and automatically destroying the needle head retraction and deflection. [0004] The present invention is composed of a syringe, a n...
