[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-5 , a device including a bottom plate 1, an adjusting traction device 2 is arranged outside the bottom plate 1, and a urinary catheterization device 3 is arranged outside the adjusting traction device 2;

[0025] The adjusting traction device 2 includes a driving motor 201, a first threaded rod 202, a moving plate 203, a telescopic rod 204, an arc plate 205, a guide rod 206, a moving sleeve 207, a mounting block 208 and a traction rope 209. The driving motor 201 is fixedly installed inside the bottom plate 1, the first threaded rod 202 is rotatably connected inside the bottom plate 1, the moving plate 203 is threadedly connected to the outer surface of the first threaded rod 202, the telescopic rod 204 is fixedly installed at the bottom of the moving plate 203, the arc plate 205 is fixedly installed at the top of the telescopic rod 204, the guide rod 206 is fixedly installed inside the arc plate 205, the moving sleeve 207 is sleeved outside the guide rod 206, the mounting block 208 is fixedly installed at the bottom of the moving sleeve 207, and the traction rope 209 is arranged outside the bottom plate 1;

[0026] The urinary catheterization device 3 includes a urinary catheter main body 301, an airbag 302, a valve air pipe 303, a drain pipe 304, a valve injection pipe 305 and a valve discharge pipe 306. The urinary catheter main body 301 is fixedly installed on the left side of the traction rope 209, the airbag 302 is fixedly installed outside the urinary catheter main body 301, the valve air pipe 303 is fixedly installed inside the urinary catheter main body 301, the drain pipe 304 is fixedly installed inside the urinary catheter main body 301, the valve injection pipe 305 is fixedly installed inside the urinary catheter main body 301, and the valve discharge pipe 306 is fixedly installed at the bottom of the drain pipe 304.

[0027] Specifically, as Figure 4As shown, the purpose of setting the steel balls is to reduce the friction between the moving sleeve 207 and the guide rod 206. When the patient changes body position, the urinary catheter device 3 will drive the traction rope 209 to move, and then drive the moving sleeve 207 to move appropriately on the outer surface of the guide rod 206 through the traction rope 209, appropriately reducing the patient's sense of restraint and improving comfort.

[0028] Specifically, as Figure 5 shown, when the urinary catheter device 3 is not needed, opening the valve trachea 303 can discharge the air inside the airbag 302, so that the airbag 302 returns to a flat state, and then the catheter main body 301 can be taken out of the patient's body to disinfect and clean the device.

[0029] Specifically, as Figure 3 shown, the drive motor 201 is a forward and reverse motor. A forward and reverse motor refers to a motor that can achieve forward and reverse rotation. The working principle of a forward and reverse motor is based on changing the phase sequence of the motor power supply to achieve a change in the rotation direction. In a three-phase asynchronous motor, by swapping any two phases, the rotation direction of the motor can be changed. This operation is called phase change, which allows the motor to run in different directions as needed.

[0030] During implementation, the operation is carried out in the following steps:

[0031] 1) First, insert the catheter main body 301 into the patient's body, and then inflate the airbag 302 through the valve trachea 303 to make the airbag 302 expand;

[0032] 2) Then, fix the catheter main body 301 through the expansion of the airbag 302, apply pressure to stop bleeding on the patient's wound surface, and then inject medicine through the valve injection tube 305 to achieve an analgesic effect;

[0033] 3) Then, turn on the drive motor 201 to drive the first threaded rod 202 to move, and cooperate with the telescopic rod 204 to adjust the position of the arc plate 205, so as to facilitate medical staff to observe or scrub the catheter connection;

[0034] 4) Finally, fix the traction rope 209 through the arc-shaped splint, and the pulley, counterweight and traction rope 209 traction the catheter, and reduce the patient's sense of restraint through the guide rod 206 and the moving sleeve 207.

[0035] In summary, for this urinary catheter traction stent, when the drive motor 201 is turned on, it drives the rotation of two first threaded rods 202 through gears and belts. Thus, the movement of the moving plate 203 is controlled by the rotation of the first threaded rods 202. Then, the arc plate 205 is moved to the connection of the patient's catheter for observing the connection of the patient, and the privacy of the patient is protected by the arc plate 205. Then, the traction rope 209 is initially fixed by rotating the bidirectional screw and the arc-shaped clamping plate. Then, the second threaded rod is rotated to drive the second rubber plate to cooperate with the first rubber plate and the spring body to perform secondary fixation on the traction rope 209. Finally, the urinary catheter is tractioned by the pulley and the counterweight, and the guide rod 206 and the moving sleeve 207 are used to ensure that when the patient's body position changes, the traction force is stable and not affected, so as to achieve the purpose of tractioning the urinary catheter and improving the comfort of the patient. The left side of the urinary catheter main body 301 is inserted into the patient's urethra, and it is ensured that the airbag 302 enters the inside of the urethra. Then, air is injected into the inside of the airbag 302 through the valve air tube 303, so that the airbag 302 expands and compresses the urethral orifice from the inside, thereby fixing the urinary catheter main body 301 inside the urethra. At the same time, the wound surface in the urethra is pressurized by the expansion of the airbag 302 to achieve the purpose of hemostasis. Then, the drug is injected into the urinary catheter main body 301 through the valve injection tube 305 and enters the patient's body to relieve pain for the patient. These used liquid medicines will be discharged from the patient's body through the drain tube 304 and the valve discharge tube 306. At the same time, normal saline and the like can also be sent into the patient's body in the same way. The blood clots in the patient's body are flushed by the normal saline, then discharged through the valve discharge tube 306, and the color of the discharged liquid of the patient is observed to ensure that the blood clots are flushed clean, so as to achieve the purpose of facilitating hemostasis and pain relief for the patient.
