In interventional operations of the department of cardiology, the operation is needed to be changed to brachial artery puncture due to the structural problems of the radial artery or the failure of radial artery puncture, and the compression hemostasis after the brachial artery puncture operation is a new problem. The traditional hemostatic method after the brachial artery interventional operation mainly adopts a gauze bandage to compress and wrap up for hemostasis, namely, the skin at the puncture point of the brachial artery is covered by a plurality of layers of gauze, the corresponding back side pad of the arm is made of hard materials, and finally, the bandage is wound and compressed for multiple times, so that the hemostatic purpose is achieved.

To solve the existing problems, the prior art publications mainly use a structure that is formed by an elbow rest/support plate, a bandage/fixing strap for fixing the elbow rest/support plate to the arm of a patient, and a compressor attached to the elbow rest/support plate. For example, chinese patent literature discloses a "joint-fixing brachial artery hemostat" (publication No. CN205964101U, publication No. 2017, month 02, day 22), which discloses a joint-fixing brachial artery hemostat, including a U-shaped elbow support, a first bandage, a second bandage, and a wristband including a compression device, the wristband includes a fixing plate, a screw, and a third bandage, a compression pad is fixed at the bottom end of the screw, a sterile gauze layer is provided on the compression pad, a displacement sensor is provided on the compression pad, the displacement sensor is connected with a control panel, and an indicator is mounted on the control panel. For another example; the Chinese patent literature discloses a brachial artery compression hemostat (publication No. CN211325324U, publication No. 2020, 25 of 08 month), and the technology discloses a brachial artery compression hemostat which comprises a supporting plate and a compression device, wherein the supporting plate is of an I-shaped structure; the support plate comprises an upper fixed end and a lower fixed end, and the upper fixed end and the lower fixed end are respectively provided with a first fixing belt which is used for fixing the support plate on the arm of a patient; the pressing device is used for pressing the puncture point, a second fixing belt is arranged on the pressing device, and the pressing device is matched with the supporting plate through the second fixing belt to realize pressing and fixing.
