Abstract

The invention relates to a tourniquet and a bleeding stopping method. The tourniquet comprises a belt, an inflating and deflating mechanism, a pressure sensor and a control circuit, wherein an annular air sac which can be inflated and deflated is arranged in the belt; the inflating and deflating mechanism is connected with the belt and is used for inflating and deflating the annular air sac; the pressure sensor is arranged on the belt and is used for detecting the pressure change between the belt and a constricted human body to output a pressure curve; and the control circuit is arranged on the belt, is connected with the pressure sensor and the inflating and deflating mechanism, and is used for performing extraction according to the pressure curve to obtain pulse waves and controlling the inflating and deflating mechanism to inflate and deflate the annular air sac according to set rules according to the changes of the pulse waves. Through detection on the pulse waves, the inflating and deflating process of the inflating and deflating mechanism is controlled, so that the pressure size of a cuff is controlled, and the purpose of stopping bleeding is achieved. A method for automatically stopping bleeding without human intervention is adopted, so that secondary hurt to wounded people is prevented.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a tourniquet and a hemostatic method. Background technique [0002] The principle of tourniquet is to compress the blood vessels by tightening the limbs, so that the diameter of the blood vessels is reduced, and then the blood in the blood vessels is blocked, thereby preventing blood from flowing out of the wound. Most of the traditional tourniquets are disposable bandages. When using this disposable bandage to stop the bleeding of the wound, the assistance of others is often needed, which is inconvenient to use. In addition, if the injured person is injured in outdoor activities, it is difficult to operate alone. However, in harsh environments, due to many uncertain factors, the wounded may be alone in some cases, so the traditional tourniquet is extremely inconvenient to use in this situation, and cannot meet the needs of harsh environments. On the other ha...
