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
[0063] The preferred solution is: when the hemostatic material outer coating is expanded into a cylindrical shape, the diameter is 10cm-12cm, and the height is 13cm-15cm; after the elastic plate 4 is expanded, the diameter is 8-12cm, the height is 0.8-1.2cm, and the thickness is 0.2-0.4cm. mm; 3 to 4 reaming blades, each 1 to 1.2 cm long. The inner diameter of the syringe is about 1.8 to 2.2 cm for better hemostasis effect;
[0064] A further preferred solution is: when the outer coating film of the hemostatic material is expanded into a cylindrical shape, the diameter is 12 centimeters and the height is 15 centimeters; the elastic plate 4: after unfolding, the diameter is 10 centimeters, the height is 1 centimeter, and the thickness is 0.3 millimeters; the reaming blade : There are 4 reaming blades, each with a length of 1.2 cm. The inner diameter of the syringe is 2 cm.
[0065] The elastic modulus of the elastic material used for the elastic plate and the splint is in the...

The invention discloses a hybrid hemostatic structure, a device and a method based on an arc elastic plate. The hybrid hemostatic structure is composed of an external hemostatic film and a mixed adaptive structure. The hybrid adaptive structure is composed of an air bag, an inflator and an adaptive elastic plate deployment structure. An adaptive elastic plate deployment structure is composed of anelastic plate and a clamping plate, wherein the elastic plate is fixed on the clamping plate and distributed in a layered shape, one in each layer, and the elastic plates of each layer are arranged according to a certain angle difference theta, and the geometric line shape of the elastic plate is an arc, and the radius of the arc is R. The elastic plate deployment structure is composed of an elastic plate and a clamping plate. The hemostatic film is attached to the outside of the elastic plate. At that time of use, the mix hemostatic structure is injected into the wound, and the inflator is open to inflate the balloon so as to drive the external application film of the hemostatic material to contact with the wound surface of the wound, the elastic plate releases elastic potential energy to radially expand to provide support for the balloon, and when the pressure meets the hemostatic condition of the wound, the inflatable device stops the hemostatic function, thereby realizing the hemostatic function.
Description
technical field [0001] The invention relates to a hybrid hemostatic structure, device and method based on an arc elastic plate, which is 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 doze...
