[0002] In routine treatment and rescue, hemostasis is required after blood is drawn through venous or arterial puncture, or after dialysis. Patients usually use hemostatic bandages to stop bleeding. Traditional hemostatic bandages still have various problems and are difficult to meet actual usage needs. When dealing with scenes such as fistulas, patients need to use hemostatic bandages all the time. However, if used improperly or for too long, the tourniquet can cause ischemia and necrosis of the distal limbs, causing disability. Therefore, after being tied for a period of time, it is necessary to relax for a while and then tie it up again. However, medical staff are often too busy to take care of this, which increases the difficulty of their work and the risk to patients. At the same time, when medical staff tie a hemostatic bandage for the patient, they also need to record the approximate binding time. However, because the hospital is too busy, medical staff easily forget to keep track of time, which makes it difficult to determine the binding time of the patient's hemostatic bandage.

[0003] The hemostatic devices currently in use have the defect of being unable to automatically relax pressure, which increases the labor intensity of medical staff and the risk to patients. After the hemostatic device is relaxed, pressure needs to be applied again, so the hemostatic device also needs to remind medical staff to apply pressure again. Utility Model Content

At the same time, the three-way valve 101d drives the synchronous ball 101e to rotate. The synchronous ball 101e will rotate to the upper part of the top cover 103b, press the top cover 103b downward, and the top cover 103b will close the pressure relief tank 103a. The sealing ring 103d ensures that the pressure relief tank 103a is sealed. At this time, the gas enters the branch pipe 102a from the inflation tube 101c, and passes through the ventilation pipe 102b- in the regulating structure 102b. 4 Enter the pressure relief tank 103a and inflate the pressure relief tank 103a. When the air pressure in the pressure relief tank 103a is greater than the air pressure inside the airbag 101b, the connecting column 104a in the pressure relief tank 103a will slide toward the arc-shaped cover 101a. When the connecting column 104a is deep enough into the arc-shaped cover 101a, the connecting hole 104b in the connecting column 104a will connect the arc-shaped cover 101a with the outside world, and the arc-shaped cover 101a is connected to the airbag 101b.
