Description

Technical Field

[0001] The utility model relates to the technical field of tourniquets, in particular to a pressure-adjustable tourniquet. Background Art

[0002] The tourniquet is made of medical polymer natural rubber or special rubber, and is long and flat. It is suitable for use in medical institutions for infusion, blood drawing, blood transfusion and hemostasis during routine treatment and rescue, or for emergency hemostasis in case of limb bleeding and bleeding caused by snakes and insects in the wild. During the use of the tourniquet, the pressure generated by the tourniquet needs to be adjusted according to the location of use;
