Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a method to solve the problem of poor hemostatic effect caused by excessive or too low hemostatic pressure when the existing tourniquet stops bleeding on the wound surface, and the wound surface is caused by the continuous compression of the blood vessels on the wound surface by the tourniquet for a long time. Pneumatic automatic hemostasis device for tissue necrosis

Abstract

The invention provides an air pressure type automatic hemostatic device. The air pressure type automatic hemostasis device is used for monitoring the pressure condition between a compression air bag and a shell, the pressure condition between the skin of a patient and a compressor is indirectly reflected, an alarm can be given in time when the condition that pressure is too large or the compression time is too long is detected, medical staff can come for treatment in time, and great convenience is brought to the patient and the medical staff; the hemostasis time of a tourniquet on the wound surface and the pressure of the tourniquet on the wound surface can be monitored; the tourniquet is automatically inflated or deflated according to the air pressure value in the tourniquet and the hemostasis time to adjust the pressure of the tourniquet on the wound surface so as to improve the hemostasis effect on the wound surface, and therefore the situation that muscle tissue on the wound surface necrotizes due to the fact that the tourniquet continuously presses blood vessels on the wound surface for a long time can be avoided.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a pneumatic automatic hemostasis device. Background technique [0002] The tourniquet is a simple and effective hemostatic device used for emergency treatment of massive bleeding in the extremities. It achieves the purpose of hemostasis by blocking the blood flow by compressing blood vessels. The tourniquet is widely used in hemostasis of arterial and venous wounds in the extremities in general surgery or hemostasis in surgical extremities. Common tourniquets in the world mainly include rubber tube tourniquets, snap-on tourniquets and inflatable tourniquets. At present, the inflatable tourniquets that appear are all tourniquets with capsules, which are composed of tourniquets with internal air bags. Although they can stop bleeding, because the air bags are wrapped in the tourniquet, the overall thickness of the tourniquet is thicker, and it needs to be use...
