Through-and-through-wound hemostatic balloon device

Abstract

The invention discloses a through-and-through-wound hemostatic balloon device, which comprises a wrinkled balloon main body which can get expanded when inflated, a balloon internal supporting soft hose, a hemostatic device fast-plug connector, a venting valve and an inflating device. The wrinkled balloon is fixed to a central soft hose, and grooves in the surface of the balloon are filled by hemostatic medicine powder. An air vent is arranged in the central soft hose, and a check valve is embedded into the air vent. The wrinkled balloon main body that initial diameter is relatively large can contract towards the centrals of hose under an internal negative-pressure circumstance, so that the size of the hemostatic device can be diminished; the device is applicable to compression hemostasis in a through-and-through wound which is 20-100mm in diameter, and through the balloon structure which gets expanded, an effect of compression hemostasis can be achieved on a bleeding point of the wound, so that geometrical shape self-adaption and contact pressure self-adaption can be achieved; and through a hemostatic material on the surface of the outer side of the balloon, an effect of drug hemostasis can be achieved on the wound, so that conformity to closed structures and wound fit can be achieved.

Description

technical field [0001] The invention relates to a hemostatic airbag device mainly suitable for penetrating wounds, belonging to the technical field of medical devices. Background technique [0002] Some military conflicts and sudden traffic accidents in recent years have rekindled people's interest in developing better hemostatic agents for penetrating wounds. In these cases, uncontrolled hemorrhage is the main cause of death for patients. Some medical experts believe that 80% of preventable deaths are caused by uncontrolled bleeding. The problem is that there are currently no effective treatments for deep penetrating wounds, which are often too severe to be bandaged, or where a tourniquet cannot be applied to the site of the injury. At present, the hemostatic treatment of penetrating wound mainly still adopts methods such as tourniquet, grease and gauze filling hemostasis. Tourniquet hemostasis is the simplest and most effective hemostasis method for emergency treatment ...

AI Technical Summary

Problems solved by technology

However, if the tourniquet is used improperly or for too long, it can cause ischemia, necrosis, and disability of the distal limbs, and there are many penetrating injuries that cannot be stopped with a tourniquet

Conventional hemostasis methods such as grease and gauze filling are far from satisfactory for the hemostasis treatment of penetrating injuries due to the limitation of treatment effect, so there is an urgent need to develop new hemostasis methods and devices
