Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and more particularly to a tourniquet with automatic tightening band pressure monitoring. Background Art

[0002] When a person suffers from a large amount of bleeding due to trauma, it is necessary to stop the bleeding in a timely and effective manner, which is of great significance for saving the lives of the wounded, stabilizing the condition of the wounded, and creating conditions for subsequent treatment. A tourniquet is usually required in the process of stopping bleeding. It is a commonly used hemostatic tool for trauma first aid in wartime, peacetime, and clinical limb surgery. Tourniquet hemostasis is a simple and effective hemostatic method used in first aid for severe bleeding in the limbs. It achieves the purpose of stopping bleeding by compressing blood vessels and blocking blood flow. However, if used improperly or for too long, the tourniquet can cause ischemia and necrosis of the distal limbs, resulting in disability. For this reason, a tourniquet can only be used when bleeding is severe and other methods cannot stop bleeding.

[0003] The principle of tourniquet hemostasis is to compress blood vessels by tightening limbs, reduce the diameter of blood vessels, and then block the blood in blood vessels, thereby preventing blood from flowing out of the wound. At present, most of the conventional tourniquets on the market use pressure hemostasis, that is, placing hemostatic cotton yarn at the wound site, and then applying a large external force on the cotton yarn. When stopping bleeding, it often requires the assistance of others, which is inconvenient to use. In addition, if the injured person is injured in outdoor activities alone, it is difficult to complete the operation alone. If used improperly or for too long, the tourniquet can cause ischemia and necrosis of the distal limbs, causing disability. Therefore, when using the tourniquet, the tightness of the tourniquet and the time control are very critical factors. When the current tourniquet is used, the injured person or the guardian needs to relax or tighten the tourniquet on time according to the manual timing method. And when a person uses a tourniquet in the wild, the person's body is severely traumatized, and it is necessary to locate its position before rescue, but the existing tourniquet does not have a positioning function.

[0004] Therefore, the purpose of the present invention is to provide a tourniquet with automatic tightening belt pressure monitoring, which can automatically adjust the tightness of the tourniquet at a regular time, and monitor the vital signs of a person and locate the position to facilitate rescue.
