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
[0039] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0040] The invention discloses an elastic plate hemostatic structure, an injection type elastic plate hemostatic device and a method. The structure is composed of a hemostatic material outer coating film and an adaptive elastic plate expansion structure. The self-adaptive elastic slab unfolded structure is composed of basic units of the self-adaptive elastic slab unfolded structure. The basic units of the self-adaptive elastic board expansion structure are distributed in layers, and the basic units of the self-adaptive elastic board expansion structure in each layer are composed of n pieces of elastic boards and support rod units. The inner end of the elastic plate is fixed on the support rod unit, and the outer coating film of the hemostatic material is wrapped on the outer side of the elastic plate. The elastic plate hemostatic structure is ...

The invention discloses an elastic-plate hemostatic structure and an injecting elastic-plate hemostatic device and method. The elastic-plate hemostatic structure comprises a hemostatic material dressing film and adaptive elastic-plate extension structures. Each adaptive elastic-plate extension structure is composed of adaptive elastic-plate extension structure basic units which are distributed inlayerwise manner; each layer of adaptive elastic-plate extension structure basic units is composed of n elastic plates and a support rod unit, the inner ends of the elastic plates are fixed to the support rod unit, and the hemostatic material dressing film covers the elastic plates. Before using, the elastic-plate hemostatic structure is stored in a syringe; upon using, the elastic-plate hemostatic structure is injected into a wound; the adaptive elastic-plate extension structures release elastic potential energy, extend radially and drive the hemostatic material dressing film, the hemostaticmaterial dressing film is attached to a wound, and a quick hemostatic function is achieved.
Description
technical field [0001] The invention relates to a hemostatic structure for penetrating wounds, in particular to an elastic plate hemostatic structure and an injection elastic plate hemostatic device, belonging to the technical field of hemostatic devices. 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...
