Description

TECHNICAL FIELD

[0001] The utility model relates to a tourniquet storage device. BACKGROUND

[0002] A tourniquet is a tool used for blood drawing and transfusion in a medical process, and it is used to achieve the purpose of hemostasis by pressing the vein. Most hospitals use rubber tubes as tourniquets for hemostasis. The tourniquet is repeatedly used, and there is a risk of cross-infection. In the prior art, some hospitals use one tourniquet for one patient to avoid cross-infection between patients. Since the tourniquet is used by one person, nurses need to prepare many sterilized tourniquets for patients to use every day. These tourniquets are placed in a tray and then placed on a treatment cart.

[0003] In a medical tourniquet storage device (patent number: CN221915623U), the device includes a box cover, a limiting groove is formed in the inside of the box cover, a positioning sleeve is fixedly connected to the inner wall of the box cover, a limiting ring is arranged inside the limiting groove, and a box body is fixedly connected to one end of the limiting ring. The device is made of plastic material, which is not easy to be polluted by water stains and the like. The box body has a small volume, which is convenient to store and saves space. A limiting piece is adhered to the rear of the box body, which can be hung in any place where nurses can easily take it. Nurses can quickly take and use the tourniquet, and the probability of crossing the sterile area during operation is reduced, thereby preventing accidental pollution of disposable consumables and reducing the incidence of hospital infection events. By pulling one end of the tourniquet to one side to drive the rotating cylinder to rotate on the surface of the supporting rod to one side, the tourniquet is extracted, thereby facilitating nurses to quickly extract and use the tourniquet. However, the device is not convenient for nurses to extract the tourniquet every time, because the tourniquet is soft and easy to be stuck in the outlet, which affects the convenience of use.
