Shear hinge and airbag mixed hemostatic structure and hemostatic device

Abstract

The invention discloses a shear hinge and an airbag mixed hemostatic structure and a hemostatic device, wherein the hemostatic structure composes a hemostatic material external applied film and a mixed adaptive structure. The mixed adaptive structure comprises an airbag, an inflatable device and an adaptive shear hinge expansion structure. The lower end of the airbag is fixedly connected to a support rod. The adaptive shear hinge expansion structure consists of a support bar and a shear hinge structure unit. The inner end of the shear hinge structure unit is fixed on the support rod, and the outer applied film of hemostatic material is affixed to the outer side of the airbag. The mixed hemostatic structure is injected into the wound when in use. The inflatable device is opened to inflate the airbag so as to drive the external applied film of hemostatic material to contact with the wound, and the elastic potential energy is released by an elastic element to drive the shear hinge structure unit to provide support for the airbag in a radial direction. When the pressure meets the pressure of the wound pressure hemostatic conditions, the inflatable device stops inflating, thus achievinghemostatic function.

Description

technical field [0001] The invention relates to a novel 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 mic...

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
