A thrombus is a small piece of blood that forms on the surface of a vessel in the cardiovascular system where the lining has been peeled off or repaired. Among them, the cause of venous thrombosis is mostly blood stasis. For patients who need to brake or partially brake due to trauma, surgery or various pathological conditions, the blood circulation of limbs slows down, and venous thrombosis is prone to occur.

At present, various pressurized bandages are mainly used clinically for postoperative limb pressurized dressing. This method has many disadvantages: it is difficult to achieve uniform bandage pressure, and the specific degree of pressurization is difficult to control. If the pressure is not enough, the purpose of pressurized bandage cannot be achieved; if the pressure is uneven, local venous pressure may increase, and venous Blood stasis can cause thrombus and incision edema, affect the healing of incision, and even increase the chance of infection; if the pressure is too high, it will affect the local blood supply. If the pressure exceeds the venous pressure, it will aggravate incision bleeding.
