A sealing cover 260 is arranged at the interface 250, and ball valves 232 are arranged at the liquid injection port 221 and the liquid outlet 222.
When the tube floating phenomenon occurs, the two ball valves 232 are opened simultaneously, wherein liquid such as physiological saline is injected into the liquid injection port 221 of the implantation sleeve 200, the corresponding ball valve 232 is closed when the liquid flows out from the liquid outlet 222 of the implantation sleeve 200, liquid is continuously injected, and certain filling pressure is provided after the liquid injection channel 121 is full, so that the tube wall of the liquid injection channel 121 is tightened, and the inner tube 110 is limited to be in a straight state and difficult to bend.
Accordingly, the injection channel 121 may be provided in a U-shape, a spiral shape, or the like along the injection direction of the peritoneal dialysis tubing 100. Referring to fig. 4, a U-shaped liquid injection channel 121 is shown, and for example, the outer tube 120 and the inner tube 110 may be pressed at two opposite generatrices, so that the connection between the outer tube 120 and the inner tube 110 may be strengthened to enhance the overall stability of the kidney, viscera, and peritoneum dialysis tube, and the U-shaped liquid injection channel 121 may be formed to facilitate the liquid injection and air exhaust of the liquid injection channel 121.
