Spiral spring hemostasis structure with inhaul cable and injection type spiral spring hemostasis device

Abstract

The invention discloses a spiral spring hemostasis structure with an inhaul cable and an injection type spiral spring hemostasis device. The hemostasis structure is composed of a hemostasis material external application film and a self-adaptive spiral spring unfolding structure. The self-adaptive spiral spring unfolding structure is composed of spiral springs, a supporting rod and the inhaul cable. The spiral springs are distributed in layers and fixed to the supporting rod, and one spiral spring is located in one layer. The hemostasis material external application film is fixed to the outer ends of the spiral springs. The supporting rod is composed of an ordinary shear type reamer unit, a special shear type reamer unit and a supporting rod elastic element. One end of the inhaul cable is fixed to the spiral springs, and the other end of the inhaul cable is led out through the supporting rod. The inhaul cable is pulled tight and fixed before use, and the spiral spring hemostasis structure is stored in an injector. In use, the hemostasis structure is injected in a wound, the inhaul cable is loosened, the spiral springs release elastic potential energy, the hemostasis structure expands in the radial direction, the hemostasis material external application film is driven to fit the wound, and therefore rapid hemostasis is realized.

Description

technical field [0001] The invention relates to a novel hemostasis structure for penetrating wounds, in particular to an adaptive helical spring hemostasis structure and an injection-type hemostasis device for helical springs. 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...

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
