Foldable mixed hemostatic structure and hemostatic device

Abstract

The invention discloses a foldable mixed hemostatic structure and a hemostatic device, wherein the hemostatic structure consists of an externally film of a hemostatic material and a mixed self-adaptive structure; the mixed adaptive structure consists of an air bag, an inflation device and adaptive scissor hinge deployment structures; the external film of the hemostatic material is pasted and fixedon the outer side of the air bag; the inflation device is connected to the upper end of the air bag and can charge or withdraw air into the air bag; the adaptive scissor hinge deployment structures consist of scissor hinge structural units and supporting rods; the scissor hinge structure units consist of scissor hinge units and elastic components; the supporting rods consist of supporting rod scissor hinge units and supporting rod elastic components. When in use, the hemostatic structure is injected into the wound, the supporting rods expand along the axial direction, the inflation device isopened 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, the scissor hinge structure units expand along the radialdirection 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 novel penetrating wound hemostasis structure, in particular to an adaptive foldable hybrid hemostasis structure and an injectable foldable hybrid hemostasis structure. 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 o...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to address the above-mentioned deficiencies in the prior art. The outer coating film of the hemostatic material is designed to cooperate with the hybrid self-adaptive structure with shape and pressure self-adaption to quickly expand and fill the penetrating wound, and the outer coating film of the hemostatic material is wrapped in The surface of the hybrid adaptive structure releases the elastic potential energy through the scissor hinge structure unit and inflates the airbag to expand it. The hybrid adaptive structure deforms according to the geometry of the wound and the elasticity of human tissue, and fills it with the hemostatic material external film. Injure the wound and adhere to the wound surface to achieve rapid filling, blood coagulation, and hemostasis, saving the lives of wounded soldiers in battle
