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

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] Such as figure 1 As shown, the injection-type helical elastic plate hemostatic device is composed of a syringe 1 , a hemostatic material outer coating 2 and an adaptive spiral elastic plate expansion structure 3 . There is a reaming blade 6 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 self-adaptive elastic plate deployment structure 3 is composed of two spiral elastic plates 4 and pins 5 , the spiral elastic plates 4 are connected by the pins 5 , and the hemostatic material coating film is paste...

Abstract

The invention discloses a helical elastic plate hemostatic structure and an injection type helical elastic plate hemostatic device. The helical elastic plate hemostatic structure comprises a hemostatic material external application film and a self-adaptive helical elastic plate unfolding structure, the self-adaptive helical elastic plate unfolding structure consists of two helical elastic plates and a pin, and the helical elastic plates are connected through the pin; the hemostatic material external application film is fixed on the outer sides of the helical elastic plates. The self-adaptive helical elastic plate unfolding structure is formed by connecting the two helical elastic plates through the pin, before in use, the helical elastic plate hemostatic structure is stored in a syringe, and when in use, the hemostatic structure is injected into a wound, the self-adaptive helical elastic plates expands along the axial direction to release elastic potential energy, the hemostatic material external application film is driven to fit the wound surface so as to achieve the rapid hemostatic function.

Description

technical field [0001] The invention relates to a penetrating wound hemostasis structure, in particular to an adaptive spiral elastic plate hemostasis structure and an injection type spiral elastic plate 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 doz...
