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

[0048] The preferred solution is: when the outer coating film of the hemostatic material is deployed into a cylindrical shape, the diameter is 10cm-12cm, the height is 13cm-15cm, the number of reaming blades is 3-4 pieces, and the length of each piece is 1-1.2cm. The inner diameter of the syringe is about 1.8 to 2.2 cm for better hemostasis effect;

[0049] A further preferred solution is: when the outer coating film of the hemostatic material is expanded into a cylindrical shape, the diameter is 12 cm and the height is 15 cm; the reaming blades: there are 4 reaming blades, each of which is 1.2 cm long. The inner diameter of the syringe is 2 cm.

[0050] The elastic modulus of the elastic material used by the polygonal unit 6 and the elastic hinge 7 is in the range of 50-150 GPa, so as to simultaneously satisfy the hemostatic effect and provide an appropriate force for penetrating the wound.

[0051] The unfolded structure of the present invention has the characteristic of se...

Abstract

The invention discloses a mesh hemostasis structure, device and method. The structure comprises a hemostasis material external application film and an adaptive mesh unfolding structure. The adaptive mesh unfolding structure comprises a mesh structure units and connecting rods. The mesh structure units comprise polygonal units and elastic hinges. The polygonal units in the mesh structure units areconnected through the elastic hinges, and the polygonal units between the adjacent mesh structure units are connected through the connecting rods. The mesh hemostasis structure is stored in a syringebefore use, the hemostasis structure is injected into a wound when in use, the adaptive mesh unfolding structure releases elastic potential energy, the volume of the adaptive mesh unfolding structureexpands, the hemostasis material external application film is driven to fit with the surface of the wound, and a rapid hemostasis function is achieved.

Description

technical field [0001] The invention relates to an adaptive mesh hemostatic structure, 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 doctors inject...
