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

[0036] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0037] Excessive blood loss caused by penetrating wounds on the battlefield is one of the important factors causing casualties, but there is no better and effective method to stop bleeding from penetrating wounds. The existing hemostasis treatment of penetrating wounds on the battlefield mainly adopts compression hemostasis, burning hemostasis, grease and gauze filling hemostasis, etc. These conventional hemostasis methods are far from meeting the first aid requirements for hemostasis of penetrating wounds due to the time-consuming conditions or the limitation of treatment effect. There is an urgent need to develop a new hemostatic method and device to fill the gap. The design of the present invention uses the hemostatic material to cooperate with the expansion structure to quickly expand and fill the penetrating wound, wrap the hemostatic m...

Abstract

The invention discloses an arc elastic plate hemostasis structure and device and a method. The structure is composed of hemostasis material external application film and a self-adaptive elastic plateunfolding structure. The self-adaptive elastic plate unfolding structure is composed of elastic plates and clamping plates; the elastic plates are fixed to the clamping plates and distributed in layers, wherein each layer is provided with one elastic plate, all the layers of elastic plates are distributed according to certain angle difference theta, the geometric linetype of the elastic plates isarc, and the arc radius is R. The hemostasis material external application film is attached and fixed to the outer sides of the elastic plates. Before use, the arc elastic plate hemostasis structure is stored in a syringe; during use, the hemostasis structure is injected to the wound, the self-adaptive elastic plate unfolding structure releases elastic potential energy and extends in the radial direction to drive a hemostasis material to fit the wound surface, and thus the quick hemostasis function is achieved.

Description

technical field [0001] The invention relates to a hemostatic structure of an arc elastic plate, a hemostatic device and a hemostatic method, which are used for the hemostatic treatment of penetrating wounds in the battlefield. 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. [0003] 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 docto...
