Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a hemostatic device for directly pressing the radial artery. Background Art

[0002] Using a radial artery compression hemostat to compress the radial artery puncture point after surgery is currently one of the main means of preventing postoperative massive bleeding. The radial artery compression hemostat is suitable for departments such as catheterization rooms, interventional departments, radiology departments, and dialysis departments. It is mainly used to stop bleeding at the puncture site after radial artery puncture. At present, a common problem encountered in the clinical use of radial artery compression hemostat is that the bending of the patient's radial joint causes displacement between the compression hemostat and the artery, affecting the effect of compression hemostasis. Especially for interventional patients with systemic heparinization, because heparin has an anticoagulant effect and may induce thrombocytopenia, if the radial artery compression hemostat cannot achieve a good compression effect on the postoperative radial artery puncture point, it is likely to cause massive bleeding.

[0003] To solve the above problems, a Chinese utility model patent with publication number CN210931617U discloses a hemostat for distal radial artery puncture site. The device allows the hemostat to be worn on the human hand through a hand-worn component, and the compression portion of the hemostat can concentrate compression on the puncture point at the distal radial artery to achieve a hemostatic effect. In addition, by providing a fixing rod and a locking mechanism, the thumb can be restrained from rotating after being tied to the fixing rod, thereby avoiding the situation where the patient's thumb rotates unconsciously and pulls the punctured skin, resulting in poor compression hemostasis effect. However, the common radial artery compression hemostat is mainly composed of a spiral slider handle, a fixing plate, a compression plate, a fixing pad, a compression pad and a composite cloth. The principle is to use a spiral downward pressure to adjust the gasket to apply vertical pressure to the wound, thereby causing the occlusion of the tiny blood vessel cavity at the wound to achieve the purpose of compression hemostasis. However, clinical medical staff are accustomed to pulling out the arterial cannula after pressing, and then putting on and rotating the radial artery compression hemostat for compression hemostasis, which is inconvenient to operate. In addition, the compression is performed in the form of spiral downward pressure, and the rotation speed is slow. Before the compression is in place, a certain amount of blood may flow out, which will contaminate the instrument and easily cause cross infection.

[0004] How to solve the above problems has become a technical problem that needs to be solved urgently. Utility Model Content
