s1, opening the cover, pulling the locking rod, enabling the locking rod to drive the clamping block, enabling the clamping block to compress the elastic piece, enabling the locking rod to be separated from the fifth groove, enabling the fixing piece to be unlocked, loosening the locking rod, enabling the clamping block and the locking rod to rebound to the original positions through the elastic piece, opening the cover plate of the disinfection device, enabling the cover plate of the disinfection device to rotate clockwise around the shell of the disinfection device through the hinge, and enabling the pressing device and the clamping plate to rotate clockwise to be separated from the titanium joint fixing seat and;

s2, fixing a disinfection conduit, extending a titanium joint into the disinfection device shell from a fourth groove and clamping and fixing the titanium joint on a titanium joint fixing seat, closing a disinfection device cover plate, enabling the disinfection device cover plate to rotate anticlockwise around the disinfection device shell as an axis through a hinge, enabling a fixing piece, a pressing device and a clamping plate to rotate anticlockwise to be respectively contacted with a first groove, the titanium joint fixing seat and the fourth groove, enabling the fixing piece to be contacted with one end of a locking rod in the downward movement process to push the locking rod to move leftwards, enabling the locking rod to drive a clamping block to move leftwards, enabling the clamping block to compress an elastic piece, enabling the locking rod to continue to move downwards, enabling a fifth groove and the locking rod to be positioned on the same horizontal line, enabling the locking rod to lose; the roller arranged inside the pressing device is contacted with the titanium joint in the clockwise rotation process of the pressing device to press the titanium joint; the clamping plate rotates anticlockwise to the fourth groove to clamp and fix the dialysis tube, and the dialysis tube is tightly sealed;

s3, disinfecting, turning on a switch, sending a signal to a controller by the switch, controlling a water suction pump to start by the controller, pumping out disinfectant stored in a liquid storage area by the water suction pump through a connecting pipe, spraying out the disinfectant through a spray head, washing a titanium joint, collecting the washed disinfectant to the right side of a first partition plate, filtering by a first filter block, entering a filter box, filtering by a second filter block in the filter box, and then flowing back to the liquid storage area.
