Pantograph hemostatic structure and hemostatic device

Abstract

The invention discloses a pantograph hemostatic structure and a hemostatic device, wherein the pantograph hemostatic structure comprises a hemostatic material external application film and an self-adaptive pantograph unfolding structure. The self-adaptive pantograph unfolding structure consists of a pantograph structure unit and a supporting rod. The inner end of the pantograph structure unit is fixed on the supporting rod, the hemostatic material external application film is adhered and fixed on the outer side of the self-adaptive pantograph unfolding structure, the pantograph structure unitis composed of pantograph units and an elastic element, the pantograph unit is formed by connecting the centers of two rods. The two ends of the elastic element are respectively connected to the connecting hinge of the adjacent pantograph structure units. When in use, the hemostatic structure is injected into a wound, the elastic element release the elasticity and can expand the self-adaptive pantograph unfolding structure in a radial direction, and the corresponding deformation is generated according to the wound shape, and the hemostatic material external application film is driven to fit the wound surface, so that the rapid hemostasis function is achieved.

Description

technical field [0001] The invention relates to a penetrating wound hemostasis structure, in particular to an adaptive scissor hinge hemostasis structure and an injection scissor hinge 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 ...

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
