[0026] Furthermore, the first adjusting component includes a U-shaped frame 2 fixedly connected to the top of the fixing seat 1, and movable grooves 3 are provided on both sides of the inner wall of the U-shaped frame 2. A servo motor 4 is fixedly connected to the top of the U-shaped frame 2, and the output end of the servo motor 4 is sleeved with a screw 5 through a coupling, and the middle part of the screw 5 is sleeved with a square plate 6. A connecting hole 7 that is compatible with the screw 5 is penetrated through the top of the square plate 6, and both sides of the square plate 6 are fixedly connected with movable blocks 8 that are compatible with the movable groove 3. A first pulley 9 is also sleeved in the middle of the screw 5 and away from the square plate 6. The square plate 6 is sleeved in the middle part of the screw 5 through the connecting hole 7 and is slidably connected to the U-shaped frame 2 in the movable groove 3 through the movable block 8. By setting the first adjusting component, it is convenient for medical staff to drive the fixing component to adjust it to the required appropriate height position to fix the catheter, so that the device can prevent the situation where the height cannot be adjusted freely when the patient's catheter needs to be fixed, thereby making the device have the effect of diversified use.

[0027] Furthermore, the second adjustment component includes a connecting plate 10 fixedly connected to the right side of the square plate 6, the middle part of the connecting plate 10 is rotatably connected to the support rod 11 through a bearing, the bottom of the support rod 11 is provided with a second pulley 12, and the second pulley 12 is movably connected to the outside of the first pulley 9 by a belt 30. By setting up the second adjustment component, medical staff can adjust the fixing component to the required appropriate angle position to fix the catheter, so that the device can be adjusted according to the catheter without adjusting the angle of the entire device, thereby making the device easy to operate and use.

[0028] Furthermore, the fixing component includes a placement frame 13 fixedly connected to the top of the support rod 11, and two slots 14 are provided on the front of the placement frame 13. Both sides of the inner walls of the two slots 14 are fixedly connected with first springs 15. The first springs 15 are grouped in pairs and two groups are provided in total. A positioning block 16 is provided on one side of each group of first springs 15. Two rings 17 are fixedly connected to the top of the placement frame 13. Rod holes 18 are provided on the tops of the two rings 17. T-shaped rods 19 are provided in the inner cavities of the two rod holes 18. Fixed semi-rings 20 are fixedly connected to the bottoms of the two T-shaped rods 19. The outer rings of the two T-shaped rods 19 are both covered with second springs 21. Through the setting of the fixing component, it is convenient for medical staff to adjust the catheter according to the diameter of the catheter to adopt double tight fixation, so that the device can prevent the device from being unable to perform reasonable limit fixation according to actual needs during use, thereby making the device easy to use.

[0029] Furthermore, the positioning block 16 and the fixing half ring 20 are both made of rubber material, and the first spring 15 and the second spring 21 are both tin-plated springs. By using the positioning block 16 and the fixing half ring 20 made of rubber material, the catheter can be protected when it is fixed to prevent damage; by using the first spring 15 and the second spring 21 as tin-plated springs, the first spring 15 and the second spring 21 can be prevented from rusting, which can increase the service life of the first spring 15 and the second spring 21.

[0030] Furthermore, the positioning component includes a U-shaped frame 22 fixedly connected to the bottom of the fixed seat 1, two slide rails 23 are provided on the left side of the inner wall of the U-shaped frame 22, and two limit rods 24 are fixedly connected to the inner cavity of the U-shaped frame 22. A threaded rod 25 is rotatably connected to the middle part of the inner cavity of the U-shaped frame 22 through a bearing, and the bottom of the threaded rod 25 passes through the bottom of the U-shaped frame 22 and extends to the outside and is fixedly connected with a handle 26, and a clamping plate 31 is sleeved on the middle part of the threaded rod 25. Two limit holes 27 and a threaded groove 28 that are mutually compatible with the limit rod 24 and the threaded rod 25 are penetrated at the top of the clamping plate 31, and a slider 32 that is mutually compatible with the two slide rails 23 is fixedly connected to the left side of the clamping plate 31. Through the provided positioning component, it is convenient for medical staff to fix the device on bed boards of different thicknesses for use, thereby preventing patients from being inconvenienced when using the device on the bed, thereby improving the use effect of the device.

[0031] Furthermore, a hand ring 29 is fixedly connected to the bottom of the handle 26. The hand ring 29 is made of soft cotton material. The hand ring 29 made of rubber material can protect the hands of medical staff to prevent unnecessary wear and tear, thereby improving the comfort of the hands of medical staff when using it.

[0032] The working principle is that the device is first clamped on the bed board through the U-shaped frame 22, and then the handle 26 is held and the knob is turned to drive the threaded rod 25 to rotate. When the threaded rod 25 rotates, it drives the clamping plate 31 to slide on the limiting rod 24 through the limiting hole 27 and the threaded groove 28. When sliding, the slider 32 slides up and down in the slide rail 23, and the distance between the clamping plate 31 and the bed board is adjusted to fit the device. The device is fixed, which is convenient for medical staff to fix the device on bed boards of different thicknesses for use, thereby preventing the patient from being inconvenienced when using the device on the bed, thereby improving the use of the device. The output end of the servo motor 4 then drives the lead screw 5 and the first pulley 9 to rotate. When the lead screw 5 rotates, it drives the square plate 6 to slide up and down in the moving groove 3 through the connecting hole 7 and the moving block 8. When sliding, the second pulley 12 and the support rod 11 are driven by the belt 30 to rotate. The rotation of the support rod 11 drives the fixing component to rotate together, which is convenient for medical staff to adjust the fixing component to the required appropriate height position and angle position to fix the catheter. Therefore, the device can prevent the patient's catheter from being unable to be freely adjusted when the height and angle need to be adjusted when fixing the catheter. The present invention can be used in a variety of situations, and thus the present invention has the effect of diversified use. After the adjustment is completed, by holding and pulling the T-shaped rod 19 to move upward in the rod hole 18, the second spring 21 is squeezed to drive the fixed semi-ring 20 to move together, and the distance between the fixed semi-ring 20 and the circular ring 17 is adjusted. After the catheter is inserted into the circular ring 17, it is loosened so that the fixed semi-ring 20 presses and fixes the catheter, and then the two positioning blocks 16 are pressed in opposite directions through the first spring 15. The distance between the two positioning blocks 16 is adjusted according to the size of the catheter and fixed again, which can facilitate medical staff to adjust the catheter according to the diameter of the catheter and take double tight fixation, so that the present invention can prevent the present invention from being unable to perform reasonable limit fixation according to actual needs when in use, thereby making the present invention easy to use. The positioning block 16 and the fixed semi-ring 20 set as rubber material can protect the catheter when it is fixed, and damage can be prevented; the first spring 15 and the second spring 21 set as tinned springs can prevent the first spring 15 and the second spring 21 from rusting, and the service life of the first spring 15 and the second spring 21 can be increased.
