[0022] According to this specific embodiment, the sterile layer 103 is detachably connected to the pressurized chamber 101 and is located below the pressurized chamber 101. The breathable layer 104 is slidably connected to the pressurized chamber 101 and is located on the inner wall of the pressurized chamber 101. The cotton ball 102 is fixedly connected to the breathable layer 104 and is located below the breathable layer 104. The cotton ball 102 is in contact with the sterile layer 103. The connecting chamber 105 is fixedly connected to the pressurized chamber 101 and is located on the outer wall of the pressurized chamber 101. The rotating shaft 106 is fixedly connected to the connecting chamber 105 and is located on the inner wall of the connecting chamber 105. The elastic bandage 107 is connected to the rotating shaft 106. Rotatably connected and located on the outer wall of the rotating shaft 106, the auxiliary component 108 is arranged on the outer wall of the pressurizing chamber 101, and the pressurizing component 109 is arranged on the inner wall of the pressurizing chamber 101. When in use, the sterile layer 103 is opened, and the cotton ball 102 is aligned with the puncture point of the patient. The auxiliary component 108 is first used to fix the pressurizing chamber 101, and then the pressurizing component 109 is adjusted to press the cotton ball 102, and then the elastic bandage 107 is pulled to rotate on the rotating shaft 106 and wrap around the puncture site of the patient. By standardizing the pressing of the puncture point in this way, the workload of medical staff can be effectively reduced and the normal recovery of the patient can be ensured.

[0023] The cotton balls 102 and the elastic bandage 107 are both made of medical grade materials.
