Technical Field
The invention relates to an air pressure blood-dispelling tourniquet.
Background
In performing surgical limb procedures, it is necessary to tighten the blood vessels in order to reduce blood loss during the procedure. The currently used air pressure tourniquet compresses limbs and blocks blood flow through the control of air pressure on the tourniquet, thereby achieving the purpose of hemostasis. It comprises an inflation pump, an air valve, an air pressure sensor and an air pressure hemostatic cuff. The tourniquet has the defect that the tourniquet can only play a role in hemostasis, and in the blood-expelling process, after the rubber blood-expelling band is manually wound on the limb, the elastic pressure effect of the rubber blood-expelling band is utilized to expel the blood at the far-end of the limb to the near-end of the limb. Therefore, the procedure of blood-driving is time-consuming and labor-consuming, and should not meet the unified standard, which may result in more blood loss or blood-driving failure in some patient operation areas.
