[0022] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0023] Please see Figure 1-4 This patent provides a technical solution: a radial artery compression hemostat, including a housing 1 and a binding member 8. A servo motor 2 is installed inside the housing 1, and a rotating roller 3 is installed on the output shaft of the servo motor 2. The output shaft of the servo motor 2 drives the rotating roller 3 to rotate in both directions. When the servo motor 2 is de-energized and stops, the rotating roller 3 can be limited by the self-locking function of the output shaft of the servo motor 2. An installation groove 5 is provided on the housing 1, and a storage battery 6 is installed in the installation groove 5. A switch 7 is installed on the storage battery 6. The storage battery 6, the switch 7 and the servo motor 2 are electrically connected. The forward and reverse buttons of the switch 7 are controlled, and the storage battery 6 supplies power to the servo motor 2 to make it rotate in both directions. Openings are provided on both sides of the housing 1, and the two ends of the binding member 8 are inserted into the openings. The two ends of the binding member 8 are connected to the two ends of the rotating roller 3. The binding member 8 is made of a soft material.

[0024] A base 16 is mounted on the housing 1, and a pressure plate 17 is mounted on the base 16. Both the base 16 and the pressure plate 17 are made of silicone material.

[0025] In use, the binding 8 is placed on the patient's radial artery, and the pressure plate 17 on the base 16 is aligned with the puncture hole. At this time, the reverse button of the switch 7 is turned on, and the battery 6 supplies power to the servo motor 2. The output shaft of the servo motor 2 drives the rotating roller 3 to rotate in the reverse direction, so that the binding 8 is retracted into the housing 1 through the opening. The binding 8 is tightened on the patient's radial artery, and the pressure plate 17 on the base 16 applies pressure to the puncture hole to stop bleeding. It can automatically apply pressure to stop bleeding in the radial artery, which is convenient and easy to use.

[0026] The binding component 8 is a bandage 9, which is connected to the roller 3 through a connecting structure 4. There are two connecting structures 4, which are symmetrically distributed on both sides with the center line of the bandage 9 as the center.

[0027] The connecting structure 4 includes a square opening 401, a connecting strip 402, a hook 403, and a hook ring 404;

[0028] The opening is a square opening 401 on the housing 1. The connecting strap 402 passes through the square opening 401 and is connected to the roller 3. The hook 403 is installed on the connecting strap 402 and the hook ring 404 is installed on the bandage 9. The hook 403 is hooked into the hook ring 404. Before use, the hook ring 404 on the bandage 9 is hooked on the hook 403 on the connecting strap 402 (when the connecting strap 402 is half-inside the square opening 401, it can be tightened and compressed).

[0029] U-shaped frames 10 are installed on both sides of the interior of the housing 1. Pulleys 11 are rotatably connected to the U-shaped frames 10 via pins. The pulleys 11 contact the connecting belt 402. When tightened, the connecting belt 402 follows the pulleys 11. The pulleys 11 rotate on the U-shaped frames 10 via pins, so that the connecting belt 402 is guided and conveyed.

[0030] A locking block 18 is installed on the base 16, and a locking groove 19 is provided on the housing 1. The locking block 18 is engaged in the locking groove 19, and an elastic element 20 is installed in the locking block 18. Both the locking block 18 and the elastic element 20 are made of steel sheet. The locking block 18 is engaged in the locking groove 19, and the elastic element 20 enhances the elasticity of the locking block 18. When the locking block 18 on the base 16 is removed from the locking groove 19, the base 16 can be disassembled from the housing 1.

[0031] The front end of the housing 1 is provided with a cover plate 12. The four corners of the cover plate 12 are respectively provided with mounting holes 13 and the four corners of the front end of the housing 1 are respectively provided with threaded holes 14. Bolts 15 are inserted into the mounting holes 13 and are respectively fitted into the threaded holes 14. A sealing gasket 21 is installed on the cover plate 12. When the bolts 15 are turned in the opposite direction and removed from the threaded holes 14 and mounting holes 13, the cover plate 12 can be removed to open the housing 1 for easy maintenance of internal equipment. Conversely, the cover plate 12 closes the housing 1, and the sealing gasket 21 seals the gap between the cover plate 12 and the housing 1.

[0032] When using this radial artery compression hemostat, before use, hook 404 on the strap 9 is hooked onto hook 403 on the connecting strap 402. During use, the strap 9 is placed over the patient's radial artery, and the pressure plate 17 on the base 16 is aligned with the puncture hole. At this time, the reverse button on switch 7 is activated, and battery 6 supplies power to servo motor 2. The output shaft of servo motor 2 drives roller 3 to rotate in the reverse direction, causing connecting strap 402 to retract into housing 1 along the square opening 401. Connecting strap 402 then moves along pulley 11, which is connected by a pin. Rotating on the U-shaped frame 10 guides the connecting belt 402 for delivery. The strap 9 tightens on the patient's radial artery, and the pressure plate 17 on the base 16 applies pressure to the puncture hole for hemostasis. It can automatically apply pressure to the radial artery for hemostasis, making it convenient and easy to use. On the same patient, when the locking block 18 on the base 16 is removed from the locking slot 19, the base 16 can be detached from the housing 1. At the same time, the hook 404 on the strap 9 can be removed from the hook 403 on the connecting belt 402, allowing the pressure plate 17 and strap 9 to be replaced.

[0033] Although embodiments of this patent have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this patent, the scope of which is defined by the appended claims and their equivalents.
