Description

Technical Field

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

[0002] Compression hemostasis device is a temporary hemostasis device, which is widely used in the medical field. Among them, the more common one is the radial artery compression hemostasis device, which is mainly used to compress the radial artery at the wrist to achieve the purpose of hemostasis. In emergency medical situations, especially when the amount of bleeding is large and needs to be stopped quickly, the effect is particularly significant. The working principle of the radial artery compression hemostasis device is to block the blood flow by applying pressure on the radial artery, thereby reducing the amount of bleeding. When the radial artery is compressed, the blood cannot flow to the hand and can only circulate between the upper arm and the elbow.

[0003] After searching, the patent with announcement number CN218391197U discloses a compression hemostasis device, which includes a base, a self-adhesive non-woven bandage is provided on the base, a threaded rod is fixedly connected to the base, a rotating sleeve is fixedly connected to the side wall of the threaded rod, the threaded rod is threadedly connected to the base, and a pressure plate is rotatably connected to the lower end of the threaded rod.

[0004] Although the above-mentioned compression hemostasis device can compress the artery to stop bleeding, it is not convenient to judge the degree of compression of the device on the patient's wound during the process of the pressure plate being driven downward by the threaded rod, which makes it difficult for medical staff to gradually decompress the wound. In addition, the device is adhered and fixed to the patient's skin with a self-adhesive non-woven bandage, which is difficult to remove. During the removal process, the patient's sweat hair will be pulled, aggravating the patient's pain.

[0005] In view of the above problems, the utility model document proposes a compression hemostasis device. Utility Model Content

[0006] The utility model provides a compression hemostasis device, which solves the problem in the prior art that it is inconvenient to judge the degree of pressure exerted by the device on the patient's wound during the downward movement of the pressure plate driven by the threaded rod, which makes it difficult for medical staff to gradually decompress the wound, and the device is adhered and fixed to the patient's skin by a self-adhesive non-woven bandage, which makes it difficult to remove. During the removal process, the patient's sweat hair will be pulled, aggravating the patient's pain.

[0025] Comfortable wearing experience: The U-shaped comfort pad is composed of three silicone sheets stacked together, with a soft texture and good cushioning performance, which can not only improve the patient's wearing comfort, but also reduce the pressure on the skin caused by long-term wearing.

[0026] Safe decompression operation: Medical staff can gradually reduce the pressure of the compression plate on the radial artery by rotating the cross screw cap according to the patient's reaction and bleeding situation. This gradual decompression method can ensure the safety of the patient and reduce the risk of bleeding caused by sudden decompression.

[0027] The utility model can quickly and effectively compress the radial artery to stop bleeding. At the same time, the device is equipped with a pressurization degree observation component, so that medical staff can intuitively judge the degree of compression and perform gradual decompression operations. In addition, the device also adopts U-shaped comfort pads and buffer gaskets to improve the wearing comfort of patients. BRIEF DESCRIPTION OF THE DRAWINGS
