When in use, only need to clamp the fixed seat 11 on the edge of the hospital bed, and then pass the catheter through the traction mechanism 18 and clamp and fix it through the internal roller 185.

[0030] The present application will be described below with reference to the accompanying drawings and specific embodiments:

[0031] Combined withFigures 1-4 , an embodiment of the present application provides a catheter traction device, including a support device 1; the support device 1 includes: a fixing rod 12 is arranged at the bottom of the fixing seat 11, and the fixing rod 12 is threadedly connected to the fixing seat 11; a fixing block 13 is arranged at the top of the fixing rod 12; a support rod 14 is arranged at the top of the fixing seat 11; a support rod 15 is arranged at the top of the support rod 15; a connecting seat 17 is arranged at one end of the support rod 15; a traction mechanism 18 is arranged at the bottom of the connecting seat 17, and the traction mechanism 18 includes: a through hole 182 is opened in the outer shell 181; a shaft body 183 is arranged on the inner wall of the through hole 182; a roller 185 is sleeved on the outer side wall of the shaft body 183.

[0032] When in use, the fixing seat 11 is clamped on the edge of the hospital bed, and then the fixing rod 12 is rotated to fix the fixing seat 11 and the hospital bed through the fixing block 13. The catheter passes through the traction mechanism and is suspended on the hospital bed with the help of the support rod 14 and the support rod 15. When the catheter needs to be pulled, the setting of the roller 185 can reduce the friction of the catheter and can also fix the catheter. The structure is simple and the operation is convenient.

[0033] In some embodiments, sliders 184 are rotatably connected to both ends of the shaft body 183, a sliding groove 186 for cooperating with the sliders 184 is opened on the inner wall of the outer shell 181, and a first spring 187 for cooperating with the sliders 184 is arranged on the inner wall of the sliding groove 186. When the diameter of the catheter changes, the shaft body 183 fixing the roller 185 slides in the sliding groove 186 through the slider 184 and clamps the middle catheter with the help of the first spring 187.

[0034] In some embodiments, a support rod 16 is arranged inside the support rod 15, the connecting seat 17 is connected to the support rod 15 through the support rod 16, a second pin 151 is arranged through the support rod 15 and the support rod 16, and a fixing groove 161 for cooperating with the second pin 151 is opened on the outer side wall of the support rod 16. Pull the support rod 16 out of the support rod 15, and then insert the second pin 151 into the fixing groove 161 on the support rod 16 to fix the support rod 15 and the support rod 16 and change the position of the traction mechanism 18.

The auxiliary assembly 2 includes: a gear 21 sleeved on the outer side wall of the first support rod 14, and the first support rod 14 is rotatably connected to the fixed seat 11; a housing 22 is provided on the top of the fixed seat 11 to accommodate the gear 21; a second fixed rod 23 is provided on the outer side wall of the housing 22 and passes through the housing 22; a second spring 24 is sleeved on the outer side wall of the second fixed rod 23; a clamping block 25 is provided at one end of the second fixed rod 23 and is clamped with the gear 21. The first support rod 14 can rotate on the fixed seat 11. Pull the second fixed rod 23 outwards to separate the clamping block 25 from the gear 21 on the first support rod 14, and then rotate the first support rod 14 to adjust the angle. After the angle adjustment is completed, release the second fixed rod 23. With the help of the second spring 24, the second fixed rod 23 drives the clamping block 25 to closely fit with the gear 21 to prevent the gear 21 and the first support rod 14 from rotating further.

[0038] In some embodiments, a protective shell 26 is provided on the outer side wall of the second fixed rod 23. The protective shell 26 can protect the second spring 24.

[0039] In some embodiments, a rubber pad 131 is provided on the top of the fixed block 13. The rubber pad 131 increases the friction between the fixed block 13 and the edge of the hospital bed.
