Technical Field
The utility model provides a pressing type hemostasis device with selectivity and controllability for human lower limbs, belonging to the technical field of intraoperative hemorrhage control in medical practice and wounded first aid in hospital or war.
Background
At present, in the four-limb operation, in order to reduce bleeding and ensure clear operation vision, a tourniquet is frequently used, and the tourniquet used at present achieves the aim by blocking blood flow entering the far section of the cerclage part in an annular binding mode through the rise of air pressure which exceeds the entering pressure of limbs. This indiscriminate binding not only blocks blood flow, but also compresses and blocks blood supply to tissues other than the blood vessel, which can present a number of limitations and complications. Firstly, the tourniquet can completely block blood supply and blood flow of blood vessels at the far section of the limb tourniquet, and many blood vessels which do not need to be blocked are also blocked, so that certain adverse effects can be caused to the body of a patient, particularly, ischemic damage can easily occur to peripheral nerves and muscles; secondly, once the tourniquet is released after the operation, a large amount of blood can be instantly gushed out from the blocked blood vessel, the bleeding amount is large, the hemostasis is difficult to realize, the reperfusion injury occurs, and various blocked tissues and organs are released to blood circulation to damage other organs of the body due to abnormal metabolic products caused by ischemia and hypoxia; thirdly, some parts close to the trunk can not be used or have poor effect, and the blood can not be effectively stopped when the large blood vessels at the root of the limbs of the transportation injury and the war injury exist in pre-hospital first aid, so that the effect of losing life due to bleeding is reduced; fourth, the degree of blockage of the distal segment of blood flow cannot be controllably reduced, but is completely blocked, which, if not completely blocked, leads to increased venous bleeding, and the surgeon often chooses to give up.
