Hemostatic structure of foldable elastic plate with pull cable, hemostatic device and hemostatic method

Abstract

The invention discloses a hemostatic structure and device of a foldable elastic plate with a pull cable, which is composed of a hemostatic material external application film and an adaptive elastic plate deployment structure. The adaptive elastic plate deployment structure is composed of the basic element of the adaptive elastic plate deployment structure and the stay cables. The basic units of the adaptive elastic plate deployment structure are distributed in a layered shape, and each layer of the basic units of the adaptive elastic plate deployment structure is composed of n elastic plates and support rod units, the inner ends of the elastic plates are fixed on the support rod units, and the hemostatic material outer coating film is wrapped on the outer sides of the elastic plates. The support bar unit is composed of a support bar shear hinge unit and a support bar elastic element. At that time of use, the hemostatic structure is inject into the wound, the pull cable is loosened, thesupport rod is radially expand, the elastic plate is radially expanded, and the hemostatic material external application film is driven to make the hemostatic material fit the wound surface, therebyrealizing the quick hemostatic function.

Description

technical field [0001] The invention relates to a hemostatic structure for penetrating wounds, in particular to a hemostatic structure with a foldable elastic plate with a cable and a hemostatic device, belonging to the technical field of hemostasis. 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,...

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
