Foldable staggered elastic-plate hemostatic structure with pull cords and hemostatic device and method

Abstract

The invention discloses a foldable staggered elastic-plate hemostatic structure with pull cords and a hemostatic device and method. The foldable staggered elastic-plate hemostatic structure comprisesa hemostatic material dressing film and adaptive elastic-plate extension structures. Each adaptive elastic-plate extension structure includes elastic plates, a support rod and a pull cord; the elasticplates are fixed to the support rod; two elastic plates form one layer; the layers of elastic plates are arranged according to a certain angle difference theta, with Pi / 3< / =theta< / =Pi / 2; geometric linearity of the elastic plates is of involutes, and base radius of each involute is R. The hemostatic material dressing film is attached to the outer sides of the elastic plates; the support rods are composed of a scissors hinge unit and an elastic element. Upon using, the foldable staggered elastic-plate hemostatic structure is injected into a wound; the pull cords are released, and the elastic elements release elastic potential energy to drive the support rods to axially extend; the elastic plates release elastic potential energy and extend radially, the hemostatic material dressing film is driven to attach to the wound, and a quick hemostatic function is achieved.

Description

technical field [0001] The invention relates to a hemostatic structure for penetrating wounds, in particular to a foldable interlaced elastic plate hemostatic structure with pull cables, a hemostatic device and method. Background technique [0002] The existing hemostasis treatment of penetrating wounds on the battlefield mainly adopts compression hemostasis, burning hemostasis, grease and gauze filling hemostasis and other methods. These conventional hemostasis methods are far from meeting the first aid requirements for hemostasis of penetrating wounds due to the limitation of wartime conditions or treatment effects. There is an urgent need to develop a new hemostatic method and device to fill the gap. RevMedx, an Oregon-based 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 ...

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
