Helical spring hemostatic structure and injection type helical spring hemostatic device

Abstract

The invention discloses a helical spring hemostatic structure and an injection type helical spring hemostatic device. The helical spring hemostatic structure comprises a hemostatic material external application film and a self-adaptive helical spring unfolding structure, wherein the self-adaptive helical spring unfolding structure consists of helical springs and a support rod; the helical springsare distributed in a layered manner, each layer is provided with one helical spring, and the bottom end is fixed on the support rod; the hemostatic material external application film is fixed at the outer end of the helical springs. The self-adaptive helical spring unfolding structure consists of helical springs and a support rod, the helical springs are distributed in a layered manner, each layeris provided with one helical spring, and the helical springs are fixed on the support rod. Before use, the helical spring hemostatic structure is stored in a syringe, and when in use, the hemostaticstructure is injected into a wound, the helical spring releases elastic potential energy, expands along the radial direction, and drives the hemostatic material external application film to fit the wound surface, thereby achieving the rapid hemostatic function.

Description

technical field [0001] The invention relates to a novel hemostasis structure for penetrating wounds, in particular to an adaptive helical spring hemostasis structure and an injection-type hemostasis device for helical springs. 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, a medical technology company in Oregon, USA, has developed a syringe-like medical device called "XStat", which contains tiny cotton wool, which can change the way military doctors treat gunshot wounds and shrapnel wounds. When in use, military doctors inject...

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
