[0002] Nephrology is a clinical department set up in hospitals at all levels for the diagnosis and treatment of kidney diseases. Common renal replacement therapies include kidney transplantation, hemodialysis and peritoneal dialysis. In renal surgical treatment, a catheter is required to drain and collect urine for patients who are unable to urinate. The existing operation method is to first puncture one end of the catheter into the patient's bladder, and then extend the other end to the side of the bed, use a pin to fix the drainage tube of the urine collection bag on the bed sheet and connect the urine collection bag. However, since the catheter is made of a soft material and is long, it is easy to cause the catheter to bend during use, which reduces the flow rate of the liquid in the catheter or obstructs the circulation, further affecting the patient's drainage efficiency, resulting in abnormal drainage of urine and affecting the patient's health. For this reason, we propose a catheter traction device. Utility Model Content

[0030] When the catheter is blocked, the rotating shaft 72 drives the pushing block 73 to rotate, and further drives the squeezing block 74 set on the pushing block 73 to rotate to contact the catheter, and squeeze and clear the catheter. The setting of the limit plate 76 and the magnetic sheet 77 can prevent the catheter from detaching, and at the same time facilitate the placement of the catheter between the control board 75 and the pushing block 73.

[0031] When in use, if the length of the catheter needs to be adjusted, the medical staff first presses the rotating block 47 to drive the driving rod 46 to move, so that the connecting plate 56 connected to the driving rod 46 drives the locking plate 57 to move, and further drives the slot 55 set on the locking plate 57 to disengage from the locking tooth 54. At this time, the rotating block 47 is rotated to drive the driving rod 46, the connecting plate 56 and the locking plate 57 to rotate, and the rotating plate 44 is driven by the driving rod 46 to rotate synchronously to store the catheter. If the catheter needs to be released, the driving rod 46 can be rotated in the opposite direction.
