[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figs. 1 to 3 A DSA postoperative arterial puncture compression device includes a main body 1. An elastic body 5 is fixedly connected to the bottom of the main body 1. A first groove 6 is formed on the side of the elastic body 5 away from the main body 1. A non-contact Hall sensor 7 is disposed inside the first groove 6 and is fixedly connected to the elastic body 5. A buzzer 8 is fixedly connected to the top of the main body 1. The non-contact Hall sensor 7 monitors the position of the main body 1 at the patient's wrist. When displacement occurs, an alarm is triggered by the buzzer 8. A threaded rod 2 is threadedly connected inside the main body 1. A pressure plate 4 is rotatably connected to the bottom of the threaded rod 2. A knob 3 is fixedly connected to the top of the threaded rod 2. The position of the pressure plate 4 is adjusted by rotating the threaded rod 2 through the knob 3.
[0021] Furthermore, a control switch 9 is fixedly connected to the top of the main body 1. The non-contact Hall sensor 7 and the buzzer 8 are both electrically connected to the control switch 9. Each electrical device is powered by a button battery, which is installed inside the main body 1.
[0022] Furthermore, there are two elastic bodies 5, which are symmetrically distributed. Since there are two elastic bodies 5, there are also two non-contact Hall sensors 7, which can better monitor the position of the main body 1.
[0023] Furthermore, the knob 3 has a second groove 10 inside, and a slider 11 is slidably connected inside the second groove 10. The slider 11 has a limiting groove 12 inside, and a limiting plate 13 is slidably connected inside the limiting groove 12. The limiting plate 13 is fixedly connected to the knob 3, and a spring 14 is fixedly connected between the limiting plate 13 and the slider 11. A rod 15 is fixedly connected to the bottom of the slider 11. The main body 1 has a slot 16 inside, and the slot 16 on the main body 1 is adapted to the rod 15. There are multiple slots 16 arranged in a ring. When the rod 15 is engaged with the slot 16, the knob 3 can limit the threaded rod 2, so that the threaded rod 2 will not automatically reverse, thereby preventing the pressure plate 4 on the threaded rod 2 from shifting between the puncture point and the patient, and avoiding bleeding at the puncture point.
[0024] Furthermore, the outer sidewall of the slider 11 fits against the inner sidewall of the second groove 10, and the slider 11 fits tightly against the second groove 10, which serves to limit the slider 11. Together with the limiting groove 12 and the limiting plate 13, the slider 11 will only slide up and down within the second groove 10.
[0025] Furthermore, straps 17 are rotatably connected to the corresponding two sides of the main body 1. One of the two straps 17 located on both sides of the main body 1 has a hook and loop fastener on the outside, and the other has a loop fastener on the outside, so that the two straps 17 can fix the main body 1 to the patient's wrist under the action of the hook and loop fastener.
[0026] The steps for using this utility model are as follows: When using this DSA postoperative arterial puncture compression device, the main body 1 is fixed to the patient's wrist by the strap 17. The slider 11 is pulled upward, causing the slider 11 to separate the insertion rod 15 from the slot 16. Then, the knob 3 is rotated clockwise. The knob 3 drives the pressure plate 4 downward through the threaded rod 2 to press down. After releasing the slider 11, the elastic force of the spring 14 will cause the insertion rod 15 to automatically engage with the corresponding slot 16, preventing reverse loosening. Then, magnetic tape is pasted on the side of the patient's wrist below the non-contact Hall sensor 7. Alternatively, medical tape can be pasted on the patient's wrist first, and then magnetic tape is pasted on top of the medical tape. If the main body 1 shifts, the non-contact Hall sensor 7 will move above the magnetic tape. At this time, the non-contact Hall sensor 7 will receive a signal and activate the buzzer 8 to alarm, reminding medical staff to make timely adjustments to prevent bleeding at the puncture site.
