A foldable staggered elastic plate hemostatic structure with a cable, and a hemostatic device and method

Abstract

The invention discloses a foldable staggered elastic plate hemostatic structure with a cable and a hemostatic device. The structure is composed of an external coating film of hemostatic material and an adaptive elastic plate expansion structure. The adaptive elastic plate expansion structure consists of elastic plates, support rods and cables. The elastic plate is fixed on the support rod. There are two elastic plates in each layer. The elastic plates in each layer are arranged according to a certain angle difference θ. The geometric linearity of the elastic plate is an involute line. The base circle radius of the involute line is R. The hemostatic material The external film is pasted and fixed on the outside of the elastic plate. The support rod consists of a scissor hinge unit and an elastic element. When in use, inject the hemostatic structure into the wound, release the cable, and the elastic element releases elastic potential energy to drive the support rod to expand in the axial direction; the elastic plate releases the elastic potential energy to expand in the radial direction, driving the external coating of the hemostatic material to fit the wound surface. Thereby achieving rapid hemostasis function.

Description

technical field [0001] The invention relates to a hemostatic structure for penetrating wounds, in particular to a foldable interlaced elastic plate hemostatic structure with pull cables, a hemostatic device and a method. 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 dozen...

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
