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

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] Such as figure 1 As shown, the injectable elastic plate hemostatic device is composed of a syringe 1 , a hemostatic material outer coating 2 and a mixed hemostatic structure 3 . There is a reaming blade 14 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 elastic plate expansion structure 6. The inflator 5 is airtightly connected to the upper end of the airbag 4 and can fill or extract gas into the airbag. The self...

Abstract

The invention discloses an elastic plate and air bag combined hemostasis structure and a hemostasis device. The hemostasis structure is composed of a hemostasis structure material external applicationfilm and a combined self-adaption structure. The combined self-adaption structure is composed of an air bag, an inflation device and a self-adaption elastic plate spreading structure. The two ends ofthe air bag are connected with the inflation device and a support rod respectively. The inflation device can detect the air pressure inside the air bag. The self-adaption elastic plate spreading structure is composed of self-adaption elastic plate spreading structure basic units. The self-adaption elastic plate spreading structure basic units are composed of elastic plates and support rod units.The support rod units are composed of support rod shear-type hinge units and support rod elastic elements. Before usage, the combined hemostasis structure is stored in an injector; when in use, the hemostasis structure is injected into a wound, support rods axially spread, the inflation device is opened to inflate the air bag to make the air bag expand, the elastic plates radially spread along with the air bag, the hemostasis structure material external application film is driven to be attached to the surface of the wound, and then a rapid hemostasis function is achieved.

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...
