Tourniquets, also known as tourniquets, are major tools used for venous blood collection, intravenous injection, hemostasis, and the like. The blood vessel puncture-preventing hemostatic bag can temporarily block venous blood flow by binding the part to be punctured, is also used for a simple and effective hemostatic method in emergency treatment of limb massive hemorrhage, and achieves the purpose of hemostasis in a short time by blocking blood circulation through compressing the blood vessel. The traditional tourniquet adopts a hose type tourniquet, but the tourniquet has the problems of intersection, repeated use, random storage, no disinfection, incomplete disinfection, overlong disinfection interval and the like. In order to solve the above problems, disposable tourniquets have come into use, which are wide and flat, and commonly used materials include natural rubber, synthetic rubber, natural latex, TEP (thermoplastic elastomer), and the like. For convenience of use, the disposable tourniquet is usually made in a form that can be cut into single sections for use or connected in multiple sections, and the disposable tourniquet connected in multiple sections is usually packaged in a roll shape.
In actual use, for convenient operation, medical staff places foretell disposable tourniquet that is web-like in the receiver, and the receiver can play accomodate dirt-proof effect, also makes things convenient for medical personnel to take simultaneously. However, the conventional tourniquet storage box has a simple structure, only has a storage function, and does not have a cutting function, when the tourniquet storage box is used, medical staff needs to pull out a proper length manually, pull the joint of the tourniquet, and pull the tourniquet along the notch with great force, so that the operation is laborious, and the tourniquet is easy to deform due to the great pulling. In order to solve the above-described problems, a tourniquet dispenser having automatic tape cutting and dispensing functions has been developed.
