Hemostatic structure and device combining airbag with elastic plate

Abstract

The invention discloses a hemostatic structure and device combining an airbag with an elastic plate. The hemostatic structure is composed of an external hemostatic material membrane and a mixed self-adaptive structure. The mixed self-adaptive structure is composed of the airbag, an inflating device and a self-adaptive elastic plate unfolding structure. The upper end of the airbag is in sealed connection with the inflating device. A basic unit of the self-adaptive elastic plate unfolding structure is a self-adaptive elastic plate unfolding structure base unit which is composed of the elastic plate and a supporting rod unit, and the elastic plate is fixed to a supporting rod. Before use, the mixed hemostatic structure is stored in a syringe, and during use, the mixed hemostatic structure isinjected into a wound; the inflating device is opened to inflate the airbag to make the airbag expand, and therefore the external hemostatic material membrane is driven to be in contact with the woundsurface; the elastic plate releases elastic potential energy which expands radially for supporting the airbag, and after pressure satisfies a hemostatic pressing condition for the wound, inflation isstopped, so that a hemostatic 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...

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
