Special injector for telescopic push rod type chain hemostatic device

Abstract

The invention discloses a special injector for a telescopic push rod type chain hemostatic device. The injector comprises an injection tube used for storing the chain hemostatic device and a pushing mechanism used for pushing the injection tube to move; a grip which is perpendicular to the injection tube and extends outwards is fixed at the tail part of the injection tube; the pushing mechanism comprises a lock catch piece sleeved on the outer sidewall of the tail part of the injection tube, an upper cover plate and a lower cover plate which are symmetrically arranged, a telescopic push rod arranged in an accommodating space formed by the upper cover plate and the lower cover plate, and a tail fixing piece for fixedly connecting the telescopic push rod with the upper cover plate and the lower cover plate; one end of the telescopic push rod penetrates into the injection tube to push the chain type hemostasis device, and the other end is connected with the tail fixing piece; one ends ofthe upper cover plate and the lower cover plate symmetrically penetrate into a locking fastener to fix the positions of the upper cover piece, the lower cover piece and the locking fastener, and the other ends of the upper cover plate and the lower cover plate are connected with the tail fixing piece; and after the telescopic push rod contracts, the injection tube penetrates through the locking fastener and then is accommodated in the accommodating space between the upper cover plate and the lower cover plate towards the direction of the telescopic push rod.

Description

technical field [0001] The invention relates to a special syringe for a telescopic push rod type chain hemostasis device, which is used in special occasions such as battlefield first aid, and belongs to the technical field of medical equipment. Background technique [0002] In first aid on the battlefield, hemostasis is a crucial link. According to relevant data, the cases of death caused by uncontrollable massive blood loss after injury account for more than 90% of the recoverable deaths. Especially after a gunshot wound, hemostasis must Timely and effective, otherwise it is very easy to lose blood and die. Existing medical devices for hemostasis mainly include gauze and tourniquet. When using gauze to stop bleeding, the gauze needs to be stuffed into the bleeding wound, but usually the wound formed by the bullet is very deep, and the method of using gauze to stop the bleeding cannot be stopped; Although hemostasis can be completed relatively quickly, after using a tourniq...

AI Technical Summary

Problems solved by technology

However, due to the deep gunshot wound and the irregular wound surface, it is inconvenient to operate the chain-type hemostatic device. Bleeding position, incomplete hemostasis, poor hemostatic effect and other issues; on the other hand, chain hemostatic devices are mainly used in the battlefield, and the protection and carrying methods have a greater impact on the use of chain hemostatic devices
