Description

Pressurization tourniquet is used in operating room nursing

Technical Field

The utility model relates to a tourniquet, specifically speaking relates to an operating room nursing is with pressurization tourniquet.

Background

Bleeding is treated in a certain way to quickly stop the outward flow of blood, which is called hemostasis. The hemostatic effect varies from person to person. Some are fast and some are slow, and platelet-related. Normally, bleeding caused by small blood vessel injury stops spontaneously within a few minutes, a phenomenon known as physiological hemostasis. Physiological hemostasis is one of the important protective mechanisms of the body and is the result of the interaction of various factors and mechanisms. The hemostasis process mainly comprises three processes of vasoconstriction, platelet thrombosis and blood coagulation, but the problem of bleeding cannot be solved by physiological hemostasis when a wound is large or an artery is injured, excessive blood loss is easily caused if the bleeding is not treated, life is threatened, the tourniquet is an uncommon hemostasis tool, the tourniquet is a simple and effective hemostasis method for emergency treatment of extremity major bleeding, and the hemostasis aim is achieved by blocking blood circulation through compressing the blood vessel. However, if the tourniquet is improperly used or used for too long time, ischemia and necrosis of a far-end limb can be caused, the traditional rubber tourniquet can only prevent blood from flowing towards a wound from one direction, but residual blood in the other direction of the limb still causes wound bleeding to affect treatment, meanwhile, the pressure of the traditional rubber tourniquet is not easy to control, patients are uncomfortable due to too tight pressure, and good hemostasis effect cannot be achieved due to too loose pressure.
