Automatic scrapping of safety syringe needles

Abstract

The invention relates to a safe syringe needle capable of being automatically scrapped. The safe syringe needle capable of being automatically scrapped comprises a hard needle tubing and an injector seat, wherein a connecting opening which extends inwards and is used for being connected with a syringe drum is formed in the center of the bottom end of the injector seat, vents distributed in the peripheral direction of the connecting opening at equal intervals are formed in the end surface of the bottom end, an annular sealing membrane parallel with the bottom end is fixed to the outer periphery of the upper end of the connecting opening, a piston piece parallel with the sealing membrane is installed in the injector seat in a sliding mode, the needle tubing is perpendicularly fixed to the piston piece, the tip of the needle tubing extends out of the top end of the injector seat, the tail end of the needle tubing penetrates through the piston piece, a centre perpendicularly pointed at the sealing membrane is further installed on the piston piece. The syringe needle is automatically scrapped after being used once, can not suck liquid any more, and is effectively prevented from being recycled.

Description

technical field [0001] The present invention relates to a medical syringe, in particular a needle. Background technique [0002] In order to ensure the safety of infusion and prevent cross-infection, all needles are disposable. In order to save costs, some informal hospitals often sterilize the used needles and put them into use again. This practice violates the rights and interests of consumers. , more seriously threatening the safety of patients' lives and property; although the country is currently strictly resisting and sanctioning this situation, the situation is still not optimistic; at the same time, the commonly used needles cannot be automatically destroyed, and patients have no easy way to get rid of it when they see a doctor. Determine whether the needles you use are secondary disinfection products. Contents of the invention [0003] In view of the above problems, the present invention provides an automatically discarded safety syringe needle, which can be self...
