Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment and relates to an anti-slip air bag type tourniquet. Background Art

[0002] A tourniquet is an essential device for orthopedic limb surgery and emergency treatment of limb vascular injuries. When in use, the tourniquet is generally wrapped around the limbs, and then the air bag inside the tourniquet is inflated to obtain pressure. When the pressure is sufficient, the blood flow can be stopped. In some situations where the tourniquet is used, it is necessary to prevent the tourniquet from sliding. For simple tourniquets without lining, they are more likely to slide during use due to the lack of a supporting structure.

[0003] In order to prevent the tourniquet from sliding, the existing practice is to add an anti-skid pad to the tourniquet, but this practice not only increases the cost of the tourniquet, but also makes the tourniquet unable to act directly on the limbs, affecting the hemostatic effect. For example, Chinese utility model patent CN202761367U (announcement date: 2013-03-06) discloses a liner-type airbag tourniquet, which is fixedly covered with an inner liner on its inner side. The inner liner uses a medical anti-skid and wear-resistant silicone pad and a rubber pad. The soft and anti-skid properties of the inner liner material itself make it easy to fit with the fixed position and prevent the tourniquet from sliding. Utility Model Content
