The telescopic tray assembly can better hold up the disinfection cup 13.

[0030] like Figure 1 and Figure 2 As shown, the catheter clamping assembly includes a first L-shaped support rod 2 and an elastic clamp 15. The bottom of the first L-shaped support rod 2 is welded to the right upper surface of the sliding support beam 3, and the other end of the first L-shaped support rod 2 is fixedly connected with the elastic clamp 15. Through the clamping assembly, the disinfection cup 13 of different diameters can be better clamped, which facilitates the titanium joint 19 to be immersed in the disinfectant inside the disinfection cup 13, freeing the hands of medical staff.

[0031] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the clamping assembly includes a first arc clamping plate 14, a supporting cylinder 24, a T-shaped round rod 25, a protective pad 26 and a second arc clamping plate 27. The inner wall of the second arc clamping plate 27 and the inner wall of the first arc clamping plate 14 are both provided with a protective pad 26. A supporting cylinder 24 is welded to the middle of the left end face of the second arc clamping plate 27, and the supporting cylinder 24 is welded to the right end face of the sliding support beam 3. Four symmetrical anti-slip grooves 28 are opened on the front and back sides of the second arc clamping plate 27. The inside of the four anti-slip grooves 28 is slidably connected with a T-shaped round rod 25, and the T-shaped round rod 25 extends through the right end face of the second arc clamping plate 27.

Through the clamping assembly, disinfection cups 13 of different diameters can be clamped to improve practicality.

[0032] The working principle and use process of the utility model: before use, the medical staff unlocks the four locking universal wheels 10 and pushes the support sleeve rod 8, which will cause the four locking universal wheels 10 to rotate and move, thereby moving the entire device. When the entire device moves the edge of the bed, and the fine-tuning telescopic beam assembly and the clamping assembly extend toward the patient, the medical staff locks the four locking universal wheels 10 to fix the entire device at the specified position. Then, the medical staff loosens and tightens the locking device 7, so that the support upright rod 6 can slide up and down inside the support sleeve rod 8, and rotate horizontally inside the support sleeve rod 8, so that the height and angle of the fine-tuning telescopic beam assembly and the clamping assembly can be adjusted. Afterwards, the medical staff turns the handle 5 clockwise to drive the threaded rod 16 to rotate forward. When the threaded rod 16 rotates forward, the L-shaped push column 17 slides to the right inside the hollow beam 4, and pushes the sliding support beam 3 to slide to the right inside the hollow beam 4, so that the clamping assembly, the catheter clamping assembly and the telescopic tray assembly are moved closer to the patient who needs to replace the peritoneal dialysis catheter 1. When the medical staff completes the fine-tuning of the distance between the clamping assembly, the catheter clamping assembly and the telescopic tray assembly and the patient, the entire device can be put into disinfection.

[0033] When performing disinfection, the medical staff first spreads a disinfection mat under the telescopic tray assembly, and then pulls the first arc clamp 14 outward, which causes the four T-shaped round rods 25 to move outward and compress the four second springs 29. When the distance between the first arc clamp 14 and the second arc clamp 27 reaches the distance for clamping the disinfection cup 13, the medical staff places the disinfection cup 13 filled with disinfectant on the disc 12.

[0034] When the disinfection cup 13 is placed on the disc 12, the second L-shaped support rod 11 and the disc 21 slide up and down inside the anti-drop sleeve 22 and the first spring 23 expands and contracts, which can provide a buffer for the disinfection cup 13 (also applicable to disinfection cups 13 of different diameters and heights).

[0035] At the same time, in the process of placing the disinfection cup 13, the medical staff slowly relaxes the force of pulling the first arc clamp 14, and the four second springs 29 will extend, pushing the four T-shaped round rods 25 to move to the left, so that the first arc clamp 14 and the second arc clamp 27 can clamp and fix the disinfection cup 13, and in the process of clamping, the protective pad 26 on the inner wall of the first arc clamp 14 and the protective pad 26 on the inner wall of the second arc clamp 27 can protect and prevent the disinfection cup 13 from slipping.

[0036] After fixing the disinfection cup 13, the medical staff immerses the titanium joint 19 in the disinfectant inside the disinfection cup 13, and clamps the peritoneal dialysis catheter 1 inside the elastic clamp 15, so that the titanium joint 19 can be vertically immersed in the disinfectant inside the disinfection cup 13, freeing the hands of the medical staff.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
