The above-mentioned belt is used to wrap around the limbs of the patient that need to stop bleeding, and the above-mentioned airbag 4 is used to provide a certain pressure for the patient's limbs to stop bleeding, so that any limbs of the patient are evenly stressed, thereby avoiding the mechanical pressure of the traditional tourniquet on local nerves The problem of local and distal nerve hypoxia with traditional tourniquets occurs. The above connecting components are used to connect the two ends of the belt body.

The above-mentioned belt body includes a silicone belt 1, the two ends of the above-mentioned silicone belt 1 are connected to form a ring structure, the above-mentioned airbag 4 is arranged in the above-mentioned silicone belt 1, and the above-mentioned airbag 4 is a belt-shaped structure matching the above-mentioned silicone belt 1.

After the two ends of the above-mentioned silicone belt 1 are connected, a ring structure can be formed, which can be used to be sleeved on the patient's limbs. After the above-mentioned airbag 4 is set in the above-mentioned silicone belt 1, it can be set around the ring structure to form the same ring structure. At this time, the air bag 4 can be gradually filled with gas by injecting gas into the air bag 4. At this time, the ring-shaped air bag 4 can uniformly act on the limbs that need hemostasis along the radial direction, which can make the need Hemostasis limbs are evenly forced to stop bleeding, which can relieve the mechanical pressure of the tourniquet on the local nerves and the hypoxia of the local and distal nerves of the tourniquet, resulting in the slowing down or even stopping of sensory and motor nerve conduction. At the same time, the uniform force can also effectively alleviate the problem of increasing the pressure on the limbs and increasing the pain of the patient caused by the excessive use of the traditional tourniquet. The above-mentioned silicone belt 1 itself has a certain degree of elasticity, so it can also effectively alleviate the pressure effect caused by driving the tourniquet when the hemostasis time is too long.

The connecting component is connected to both ends of the above-mentioned silicone belt 1, and is used to detachably connect the two ends of the above-mentioned silicone belt 1. The above-mentioned connecting components are used to detachably connect the two ends of the silicone band 1.
