Drawing type hemostatic structure based on special-shaped elastic coil spring

Abstract

The invention relates to a drawing type hemostatic structure based on a special-shaped elastic coil spring. The structure comprises a hemostatic material external application film, the special-shaped elastic coil spring and a push-out supporting column, the special-shaped elastic coil spring is composed of a plurality of basic units of the same structure and is distributed on the outer wall of the push-out supporting column, the basic units of the special-shaped elastic coil spring are distributed in a layered mode in the axial direction, the special-shaped elastic coil spring on each layer is evenly distributed in the circumferential direction, and the special-shaped elastic coil spring between the adjacent layer is arranged in a staggered mode. In an initial state, one end of the special-shaped elastic coil spring is fixed on the push-out supporting column, and the other end is fixed on a trigger mechanism; the hemostatic material external application film is connected to the special-shaped elastic coil spring; and the push-out supporting column is of a hollow structure, and in the initial state, the trigger mechanism is arranged in the push-out supporting column. Efficient and rapid hemostasis can be achieved, and the life of injured soldiers on a battlefield is saved.

Description

technical field [0001] The invention relates to a pull-type hemostatic structure based on a special-shaped elastic coil spring, which belongs to the technical field of battlefield hemostasis. Background technique [0002] Existing methods of hemostasis for penetrating wounds on the battlefield mainly include compression, burning, filling with grease and gauze, etc. These conventional hemostasis methods are far from meeting the first aid requirements for hemostasis of penetrating wounds due to wartime conditions or limited treatment effects. RevMedx, an Oregon medical technology company, has developed a syringe-like medical device called "XSTat" that contains tiny cotton wool that could change the way military doctors treat gunshot wounds and shrapnel wounds. When in use, military doctors inject dozens of pill-shaped micro cotton wool into the wound, and the cotton wool is treated with chitosan. Chitosan is able to clot blood and fight infection. In seconds, the cotton wool...

Problems solved by technology

However, this method of relying on blood-sucking expansion to stop bleeding is very dangerous for the wounded who are bleeding heavily on the battlefield, and the strength of the material becomes weak after expansion, making it difficult to provide continuous squeezing force on the wound surface, and its function needs to be further improved
