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
[0066] 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;
[0067] 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.
[0068] The elastic modulus of the elastic material used in the polygonal unit and the elastic hinge is in the range of 50-150Gpa, so as to simultaneously satisfy the hemostatic effect and provide an appropriate force for penetrating the wound.
[0069] The unfolded structure of the present invention has the characteristic of self-ad...

The invention discloses a mixed bleeding stopping structure, device and method. The structure is composed of a bleeding stopping material external application film and a mixed self-adaption structure.The mixed self-adaption structure is composed of an airbag, an inflation device and a self-adaption netty expanded structure. The upper end of the airbag is closely connected with the inflation device, and the inflation device can control the air pressure intensity of the airbag according to blood pressure. The self-adaption netty expanded structure is composed of a netty structure unit and a connecting rod. The netty structure unit is composed of a polygonal unit and an elastic hinge. The bleeding stopping material external application film is pasted and fixed to the outer side of the airbag. During use, the mixed bleeding stopping structure is injected into a wound, the inflation device is started to inflate the airbag, the airbag is expanded, therefore, the bleeding stopping material is driven to external application film is driven to be in contact with the wound surface, the netty structure unit releases elastic potential energy and is expanded in the radial direction to support the airbag, inflation is stopped after the pressure meets the wound pressing hemostasis condition, and therefore the bleeding stopping function is achieved.
Description
technical field [0001] The invention relates to a mixed 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 dozens o...
