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

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] like 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). like 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. , the...

Abstract

The invention discloses a mixed hemostatic structure. The structure consists of an external application film of hemostatic materials and a mixed self-adaptive structure. The self-adaptive structure consists of an air bag, an air inflation device and a horizontal self-adaptive scissor-like hinge deployable structure. The self-adaptive horizontal scissor-like hinge deployable structure consists of ascissor-like hinge structural unit and a perforation line, and the scissor-like hinge structural unit is connected into a whole by the perforation line. The scissor-like hinge structural unit consists of a scissor-like hinge unit and an elastic element, wherein the scissor-like hinge unit is formed by hinging four rods end to end in sequence. When in use, the mixed hemostatic structure istis injected into the wound, the inflation device is opened and the air bag is inflated to expand so that the external application film of hemostatic materials is driven to contact with the wound surface, theelastic element releases elastic potential energy to drive the scissor-like hinge structural unit to expand along the radial direction to provide support for the air bag. When the pressure meets thehemostatic condition of the wound compression hemostasis, the air inflation is stopped, so that the hemostasis function is achieved.

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...
