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

Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] Such as figure 1 As shown, the injectable hybrid hemostatic device is composed of a syringe 1 , a hemostatic material outer coating 2 and a hybrid self-adaptive structure 3 . There is a reaming blade 12 at the front end of the syringe 1, and when the wound is small, the wound is cut to put into the hemostatic device. figure 2 , image 3 Shown are the initial folded state and the state of use of the hemostatic material outer coating film 2 respectively. The hemostatic material outer coating film 2 has a certain degree of flexibility and can expand when encountering blood (water). Such as Figure 4 As shown, the hybrid adaptive structure 3 is composed of an airbag 4, an inflator 5 and an adaptive horizontal scissor hinged expansion structure 6. The inflator 5 is airtightly connected at the upper end of the airbag 4 and can fill or extract gas into the airbag. ...

Abstract

The invention discloses a horizontal sheering hinge mixed hemostatic structure and an injection mixed hemostatic device. The horizontal sheering hinge mixed hemostatic structure comprises hemostatic material external applying film and a mixed adaptive structure, wherein the mixed adaptive structure is composed of an airbag, an inflation device and an adaptive horizontal sheering hinge unfolding structure, the inflation device is connected to the upper end of the airbag and can inflate or deflate the airbag, and the adaptive horizontal sheering hinge unfolding structure is located in the airbag. When the horizontal sheering hinge mixed hemostatic structure and the injection mixed hemostatic device are used, the mixed hemostatic structure is injected into a wound, the inflation device is turned on to inflate the airbag so that the airbag dilates, thereby driving the hemostatic material external applying film to contact the wound surface of the wound, an elastic element releases elastic potential energy to drive a sheering hinge structure unit to expand radially so as to provide the airbag with support, and after the pressure meets an wound pressing hemostatic condition, inflation isstopped, thereby achieving a hemostatic 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...
