Abstract
An improved dialysis apparatus and method wherein a dialysis delivery system delivers dialysate to a dialyzer through an external dialysate line with a dialyzer inlet connector and a dialysate waste system removes spent dialysate from the dialyzer through an external spent dialysate line with a dialyzer outlet connector. A bypass block comprises a first bypass block connector adapted to connect to the dialyzer inlet connector and a second bypass block connector adapted to connect to the dialyzer outlet connector and a conduit interconnecting the first bypass block connector and the second bypass block connector with a check valve located intermediate the first and second bypass block connectors and oriented to permit fluid flow only from the first bypass block connector to the second bypass block connector. An injection device is located in the conduit intermediate the check valve and the second bypass block connector connected to a cleaning agent connector adapted for connection to a container of cleaning agent by a cleaning agent line. A pump is located in the cleaning agent line intermediate the injection device and the cleaning agent connector and oriented to pump cleaning agent from the cleaning agent connector to the bypass device with a backflow prevention valve located in the cleaning agent line intermediate the pump and the injection device and oriented to permit fluid flow only from the pump to the injection device.
