Abstract

The invention discloses a safety injector which comprises an outer sleeve, a push rod, a rubber plug and a screw opening. The outer sleeve is perpendicularly arranged, the push rod is inserted into the outer sleeve from a lower end opening of the outer sleeve, the rubber plug is arranged on the push rod in a sleeving mode and located in the outer sleeve, a rubber plug installing opening and a breakage notch are sequentially formed in the upper portion of the outer circumferential face of the push rod from top to bottom, and a push rod boss is arranged at the top end of the push rod. The screw opening is inserted into the outer sleeve from an upper end opening of the outer sleeve. The push rod boss is inserted into the screw opening from a lower end opening of the screw opening. The safety injector is simple in structure and convenient to operate, the shape damage effect on a used injector is obvious, and repeated use of the injector can be prevented.

Description

technical field [0001] The invention relates to a safety syringe and belongs to the technical field of medical instruments. Background technique [0002] In order to avoid cross-infection, syringes are generally disposable syringes, which are only used once, but the outer cover and screw port of existing syringes are generally designed in one piece. Such a design is reversible after use, that is, used syringes, After the injection needle is put on the screw port again, it can be reused, which will damage the health of consumers. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art and provide a safety syringe with simple structure, convenient operation, separate design of the jacket and the screw port, which can significantly destroy the used syringe and prevent the syringe from being reused. [0004] The technical solution to achieve the above purpose is: a safety syringe, including a jacket, a push rod, a ru...
