[0002] Traumatic bleeding accounts for a high proportion of cases in the emergency department and is one of the most common ailments, posing a significant threat to patients' lives. Bleeding also increases patients' psychological stress, and many non-medical personnel often use the persistence of bleeding as a key indicator of the patient's condition. Therefore, timely hemostasis can better protect patients' lives, reduce stress for patients and their families, and also decrease medical disputes. Common pre-hospital hemostasis methods in the emergency department include: pressure bandages, digital pressure, packing, tourniquets, and ligation.

[0003] In the prior art, Chinese Patent Publication No. CN214761297U discloses a tourniquet for trauma patients, comprising a band body and a binding strap. The band body has several symmetrical perforations at both ends, spaced apart along the width of the band body. The binding strap's two ends pass through the perforations on both sides of one end and sequentially cross through adjacent perforations. The band body includes a tourniquet layer and an auxiliary layer attached to the upper and lower surfaces of the tourniquet layer. The tourniquet layer is made of elastic rubber, and the auxiliary layer is made of cotton padding. This tourniquet, with its auxiliary layer, protects the injured skin. The binding strap, crossed and tightened through the perforations, distributes the force on the binding strap. Through the cooperation of the dressing layer and the binding strap, it reduces pressure damage to the injured skin and alleviates the patient's pain.
