[0002] In medical emergency, a tourniquet is a medical device used to control limb bleeding. It stops blood flow by applying pressure to blood vessels, thereby achieving the purpose of hemostasis. In emergency situations, during surgery or other situations that cause heavy bleeding and conventional hemostasis methods cannot effectively control bleeding, a tourniquet is used to stop bleeding. Traditional manual tourniquets usually rely on the operator's experience to judge the pressure and binding time, and it is difficult to accurately control the hemostasis effect, which can easily lead to insufficient pressure to effectively stop bleeding or excessive pressure causing tissue damage. In addition, in emergency situations, operators may not be able to use the tourniquet correctly due to nervousness or lack of professional training, resulting in excessive use of the tourniquet for too long or with too high pressure, which can cause damage to surrounding tissues and other complications that affect the treatment effect.
