The connecting valve 1022 plays a role in controlling the flow direction of the dialysate, which helps to accurately control the dialysis process and improve the effectiveness and safety of dialysis.

[0045] Furthermore, the storage structure 11 includes a storage plate 111 fixedly connected to the inner cavity of the protective frame 21 and located on the upper part of the winding frame 101, a pressure pump 112 is fixedly connected to the middle part of the left side of the upper end surface of the storage plate 111, a dialysate bag 114 is placed in the middle part of the upper end surface of the storage plate 111, and an ultraviolet sterilization lamp 113 whose size matches the upper end surface of the storage plate 111 is fixedly connected to the lower end surface of the cover plate 23.

[0046] Working principle: When working, pull the cover plate 23 to connect the inner cavity of the protection frame 21.

[0047] When the patient's external tube needs to be placed, the adjusting slide bar 542 is pressed to make the adjusting slide bar 542 slide downward, thereby making the adjusting slide bar 542 relatively rotate, so that the positioning plates 52 on both sides move away from each other, further making the positioning plates 52 rotate, so that the slider 43 slides relatively, so that the spring 42 stretches, and now the personnel inserts the external tube connected to the patient into the inner cavity of the limiting groove 33, and then releases the adjusting slide bar 542. At this time, due to the contraction of the spring 42, the slider 43 moves away from each other, so the transmission rod 51 rotates in the opposite direction, further making the positioning plates 52 on both sides approach each other, and then the external tube is squeezed and fixed by the limiting belt 532.

[0048] The electric telescopic rod 73 is started to lower the height of the upper clamping plate 74, so that the fixed clamping plates 82 on both sides clamp and fix the left side of the conveying hose 1021. At the same time, the driving structure 9 is started to rotate the output end of the driving motor 94, so the driving gear 93 rotates, and further the toothed belt 92 meshing with the driving gear 93 rotates. At this time, since the toothed belt 92 and the transmission gear 91 are meshed with each other, the transmission gear 91 rotates. Further, since the transmission gear 91 is fixedly connected to the threaded rod 63, the threaded rod 63 rotates, so that the clamping structure 7 moves to the left, so that the left connection end of the conveying hose 1021 is plugged into the external pipe.

[0049] The pressure pump 112 is started, so that the dialysate in the inner cavity of the dialysate bag 114 is transferred to the connecting valve 1022 through the connecting pipe. At this time, the connecting valve 1022 is opened, so that the dialysate is transferred to the external pipe through the delivery hose 1021. Similarly, the waste liquid after dialysis is re-transported to the inner cavity of the dialysate bag 114 through the delivery hose 1021 and the connecting valve 1022 through the pressure pump 112. At the same time, the personnel starts the ultraviolet sterilization lamp 113 to sterilize and disinfect the inner cavity of the device and the dialysate bag 114.

[0050] When dialysis is completed, the drive structure 9 is started to reverse the output end of the drive motor 94, thereby causing the drive gear 93, the toothed belt 92 and the transmission gear 91 to rotate in the opposite direction, further reversing the threaded rod 63, so that the clamping structure 7 moves to the right, thereby separating the delivery hose 1021 from the external tube.
