Safe self-destruction syringe for medical purpose

Abstract

The invention discloses a safe self-destroying medical injector, which comprises the following parts: hollow cylinder, snap coil, needle seat and core bar, wherein the plug is assembled in the core bar head; a coil of flute is set in the head of cylinder; the boss is set on the top of core bar with upper round boss and lower round boss under the boss; the easy-breakpoint is set under the lower round boss; the needle seat is composed of separable conical seat and support seat with an 'O' rubber ring between the excircle of conical seat bulk and cylinder; two through-grooves of central symmetry are set under the conical seat, which sets two bosses of central symmetry between two through-grooves; the boss snaps the flute on the cylinder; the flute is set on the inner hole bottom of conical seat.

Description

technical field [0001] The invention relates to a medical injector, in particular to a safe self-destruction medical injector in which a needle can be retracted into a syringe after injection. Background technique [0002] The practice of modern medicine has proved that in order to avoid cross-infection when injecting or taking out media for humans or animals, hypodermic syringes must be used once and disposed of as garbage after use. The most widely used disposable syringe is composed of a hollow syringe, a needle and a fixed-stroke piston fitted in the syringe. The biggest problem with this type of syringe is that after the injection is completed, the needle still stays outside. As far as the sharpness of the needle is concerned, it not only brings inconvenience to the handling and destruction of syringe waste, but also often injures medical staff due to carelessness, which inevitably leads to secondary cross-infection of germs. Especially for those syringes used by patie...

Problems solved by technology

The most widely used disposable syringe is composed of a hollow syringe, a needle and a fixed-stroke piston fitted in the syringe. The biggest problem with this type of syringe is that after the injection is completed, the needle still stays outside. As far as the sharpness of the needle is concerned, it not only brings inconvenience to the handling and destruction of syringe waste, but also often injures medical staff due to carelessness, which inevitably leads to secondary cross-infection of germs. Especially for those syringes used by patients with serious infectious diseases (such as AIDS, hepatitis, SARS, etc.), it is a medical hidden danger that cannot be ignored. Practice has shown that needlestick injuries caused by unsafe self-destructing needles are significantly more Injuries caused by other accidents
