Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a pressure-visible automatic decompression radial artery compression hemostat. Background Art

[0002] Coronary angiography is the "gold standard" for clinical diagnosis of coronary heart disease, and is also one of the commonly used minimally invasive ways to fully understand the condition of the coronary arteries and choose treatment methods. Most patients may experience bleeding at the puncture site after surgery. In order to ensure that the patient recovers as soon as possible after surgery, hemostasis must be performed on the patient. The use of a pressure pad made of transparent material is convenient for doctors or nurses to observe, and the pressure is easy to adjust, which can effectively improve the patient's comfort and prevent the occurrence of complications. The radial artery compression hemostat is a commonly used device for hemostasis at the arterial puncture point after radial artery interventional treatment. Currently, most common radial artery hemostat is a spiral pressure hemostat, which has problems such as invisible and unquantifiable pressure, and requires manual decompression every hour. Excessive pressure for a long time may cause arterial occlusion.

[0003] However, medical staff of the spiral radial artery compression hemostat often need to remember the time to start compression after the operation, and rotate the button to relax it one circle every two hours after using the compressor, which increases the workload of medical staff. They often forget the time and rotate the patient prematurely or delay the rotation time, which may cause complications such as bleeding, numbness, swelling, radial artery occlusion, etc. For this reason, we proposed a pressure-visible automatic decompression radial artery compression hemostat to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a pressure-visible automatic decompression radial artery compression hemostat to solve the problem raised in the above-mentioned background technology that the workload of medical workers is increased, and the patients often forget to rotate the patient in advance or delay the rotation time, resulting in complications such as bleeding, numbness, swelling, radial artery occlusion, etc.

[0005] To achieve the above object, the present invention provides the following technical solution: a pressure-visible automatic decompression radial artery compression hemostat, comprising a base, a fixing box is fixedly installed on the upper end of the base, two groups of fixing rods are fixedly connected on both sides of the base, a bandage is movably sleeved on the outer surface of one group of fixing rods, a radial artery pressure block is installed at the bottom of the base, and a compression mechanism is arranged inside the fixing box; The compression mechanism includes a fixed groove, a driving motor, a worm, a movable groove, a worm wheel, a threaded rod, a limiting ring, a connecting tube and a bearing.

When the hemostatic pad 510 hits the skin, it stops rotating due to friction. At this time, the connecting tube 508 still descends, and the hemostatic pad 510 is lowered to the designated position for bleeding.

[0018] The device solves the problem of increased workload of medical workers by setting up the compression mechanism 5. The problem that medical workers often forget to rotate the patient in advance or delay the rotation time may cause complications such as bleeding, numbness, swelling, radial artery occlusion, etc.

[0019] Furthermore, a pressure sensor 6 is fixedly installed at the bottom center of the hemostatic pad 510, a touch screen 9 is installed on the upper surface of the fixing box 2, and four groups of control buttons 10 are installed at the four corners of the touch screen 9 on the surface of the fixing box 2. The four groups of control buttons 10 are respectively: a pressure button, a decompression button, a timing button and a power button from left to right. Figure 4 As shown, the structure is used to set the pressure value by using the touch screen 9. When the pressure sensor 6 at the lower end of the hemostatic pad 510 obtains the set pressure value, the drive motor 502 is controlled to stop operating. The downward distance of the hemostatic pad 510 is controlled according to the pressure value set on the touch screen 9. The decompression time and the number of turns of the threaded rod 506 driven by the automatic control drive motor 502 are set according to the time point and amount of decompression required.

[0020] Furthermore, the driving motor 502 is fixedly installed in the fixed groove 501, the right end of the worm 503 is fixedly connected to the output end of the driving motor 502, the other end of the worm 503 is rotatably connected to the inner wall of the fixed groove 501, the center of the movable groove 504 is rotatably connected to the worm wheel 505, the upper end of the threaded rod 506 is fixedly connected to the worm wheel 505, the upper end of the connecting tube 508 is fixedly connected to the limit ring 507, the limit ring 507 is located on the outer surface of the threaded rod 506 and is movably connected to the threaded rod 506, the inner part of the hemostatic pad 510 is installed with a bearing 509, and the upper end of the bearing 509 is rotatably connected to the connecting tube 508. Figure 3 As shown, the structure is used to control the drive motor 502 to run in reverse every hour when the decompression time point is reached, driving the worm 503 to rotate in the opposite direction, so that the hemostatic pad 510 moves upward, reducing the pressure by 15% each time, thereby reducing the pressure intensity on the puncture site and avoiding the doctor's inability to adjust the hemostat in time.

[0021] Furthermore, a spring 7 is disposed inside the movable groove 504, the upper end of the spring 7 abuts against the limiting ring 507, and the other end of the spring 7 abuts against the inner wall of the movable groove 504. Figure 4 As shown, this structure is used to squeeze the spring 7 through the spring 7 when the limit ring 507 descends along the movable groove 504, causing the spring 7 to deform, so that the limit ring 507 drives the connecting pipe 508 to move downward stably. At the same time, it plays a tightening role between the limit ring 507 and the movable groove 504 to prevent the limit ring 507 from rotating on its own.

[0022] Furthermore, a CPU module 11 is installed inside the fixing slot 501 on the side opposite to the driving motor 502, and a wireless communication module 12 is installed inside the fixing slot 501 on the front side of the CPU module 11. The CPU module 11 and the wireless communication module 12 are electrically connected to the touch screen 9 and the driving motor 502. Figure 5 As shown, the structure is used to control the operation of the drive motor 502 through the CPU module 11, drive the hemostatic pad 510 to adjust the position, and send a prompt signal to the mobile device of the medical staff through the wireless communication module 12 to remind the doctor to come and check and observe whether the skin color of the patient's puncture site is abnormal, so as to facilitate timely adjustment of the pressure.

[0023] Furthermore, two groups of batteries 13 are installed in the fixing slot 501 in front of the driving motor 502, a cover plate 14 is movably connected to the right side of the fixing box 2, and a charging port 15 is installed on the right side surface of the fixing box 2 to facilitate charging the device. Figure 2 and Figure 5 As shown, the structure is used to supply power through a battery 13, and the battery 13 can be easily replaced or repaired through a side cover 14.

[0024] Furthermore, four groups of heat dissipation holes 16 are provided on the rear side of the fixing box 2, and the front ends of the heat dissipation holes 16 face the driving motor 502. A speaker 17 is installed on the rear side of the fixing box 2. Figure 2 As shown, the structure is used to dissipate heat from the drive motor 502 through the heat dissipation hole 16, thereby preventing the high temperature generated by the drive motor 502 from being transferred to the base 1 after operation, thereby increasing the service life of the device, and providing a sound reminder through the speaker 17 when the preset time is reached.

[0025] Working principle: When used, Figure 1 As shown, the hemostatic pad 510 is placed at the puncture site, the strap 4 is passed around the wrist, passed through another set of fixing rods 3, and then fixed with Velcro, and the base 1 together with the hemostatic pad 510 is fixed at the puncture site, as shown in FIG. Figure 2 As shown, by pressing the control button 10 on the surface of the fixing box 2 to start the touch display screen 9, the pressure value can be set using the touch display screen 9, such as Figure 3 and Figure 5 As shown, the CPU module 11 controls the driving motor 502 to run according to the set value, drives the worm 503 to rotate, and makes the worm wheel 505 drive the threaded rod 506 to rotate, and is movably connected with the threaded rod 506 through the limit ring 507, so that the limit ring 507 and the connecting tube 508 move downward along the threaded rod 506 and the movable groove 504, and drive the hemostatic pad 510 to descend. The connecting tube 508 is connected with the hemostatic pad 510 below it through the bearing 509. When the hemostatic pad 510 hits the skin, it stops rotating due to friction. At this time, the connecting tube 508 still descends. When the pressure sensor 6 at the lower end of the hemostatic pad 510 obtains the set pressure value, the driving motor 502 is controlled to stop operating. The downward pressing distance of the hemostatic pad 510 is controlled according to the pressure value set by the touch display screen 9. The decompression time and the number of revolutions of the threaded rod 506 driven by the automatic control driving motor 502 are set according to the required decompression time point and the required decompression amount. Figure 4 As shown, when the limiting ring 507 descends along the movable groove 504, the spring 7 is squeezed to deform the spring 7, so that the limiting ring 507 drives the connecting pipe 508 to move downward stably. At the same time, the limiting ring 507 and the movable groove 504 are tightened to prevent the limiting ring 507 from rotating by itself. Figure 3 and Figure 5As shown, when the decompression time point is reached every hour, a sound reminder is given through the speaker 17 when the preset time is reached, and the CPU module 11 controls the drive motor 502 to run in reverse, driving the worm 503 to rotate in the opposite direction, so that the hemostatic pad 510 moves upward, and the pressure is reduced by 15% each time, thereby reducing the pressure intensity on the puncture site, avoiding the doctor's inability to adjust the hemostat in time. At the same time, a prompt signal is sent to the mobile device of the medical staff through the wireless communication module 12 to remind the doctor to come and check and observe whether the skin color of the patient's puncture site is abnormal, so as to facilitate timely adjustment of the pressure. The above is the entire working principle of the present invention.
