Safety self-destructive syringe

Abstract

The invention discloses a safety self-destructive syringe. The syringe comprises a protective cap, a syringe needle, a cylinder, a push rod and a syringe needle protective device. The syringe needle comprises a needle seat and a needle tip installed on the needle seat, the protective cap is fixedly arranged on the syringe needle, the syringe needle is installed at the front end of the cylinder through the syringe needle protective device, the push rod with an o-shaped piston is installed in a hollow cavity of the cylinder, and therefore the safety self-destruction syringe is formed. The syringe needle protective device comprises a 6:100 Ruhr rotary union, a protective arm, a hinge and a buckle, wherein the 6:100 Ruhr rotary union enables the syringe needle and the cylinder to be connected together, the syringe needle is contained in the protective arm, and the hinge and the buckle enables the syringe needle to be located. The hinge is connected between the outer circumferential surface of the upper end of the 6:100 Ruhr rotary union and the bottom face, close to the lateral side, of the protective arm to enable the protective arm to rotate relative to the 6:100 Ruhr rotary union. The safety self-destructive syringe is simple in structure, easy to operate, capable of conducting protection and self-destruction on the polluted syringe needle after injection ends, and therefore the syringe needle is prevented from piercing people again and the syringe is prevented from being reused.

Description

technical field [0001] The invention relates to a safe self-destructing syringe, in particular to a safe self-destructing syringe with a needle protection device, especially capable of preventing the needles used in medical devices such as syringes from accidentally stabbing medical staff or cleaning personnel and syringes after use. use. Background technique [0002] At present, traditional disposable syringes are still widely used and sold on the market. Because they do not have safety and self-destruct functions, especially because accidental stab wounds, illegal recycling, and repeated use are difficult to prohibit, they cause potential safety hazards in clinical use. It also brings problems for the subsequent harmless treatment. [0003] In medical practice, medical devices with sharp needles are widely used, such as syringes, blood collection devices and the like. These medical devices are not only used and handled by professionals in medical institutions, but also o...
