Foldable air bag and staggered elastic plate mixed hemostatic structure and hemostatic device

Abstract

The invention discloses a foldable air bag and a staggered elastic plate mixed hemostatic structure and a hemostatic device, wherein the hemostatic structure consists of an external film of a hemostatic material and a mixed self-adaptive structure; the mixed adaptive structure consists of an air bag, an inflation device and self-adaptive elastic plate deployment structures; the upper end of the air bag is hermetically connected with the inflation device; the self-adaptive elastic plate deployment structures consist of elastic plates and supporting rods; the elastic plates are fixed on the supporting rods; each layer has two the elastic plates, the elastic plates at each layer are arranged according to a certain angle difference, and the geometric linearity of the elastic plates is involutecurve; and the external film of the hemostatic material is pasted and fixed on the outer side of the air bag. When in use, the mixed hemostatic structure is injected into the wound, the inflation device is opened to inflate the air bag to inflate the air bag to drive the external film of the hemostatic material to contact with the wound surface of the wound; the elastic plates release elastic potential energy to expand along the radial direction to provide support for the air bag, and inflation is stopped when the pressure meets the hemostatic condition of the wound pressing, so that the hemostatic function is realized.

Description

technical field [0001] The invention relates to a penetrating wound hemostasis structure, in particular to an adaptive hybrid hemostasis structure and an injection-type hybrid hemostasis device. 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 dozens of pill-shaped micro cot...

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
