Abstract
A dialysis machine is described which provides for the detection of leakage anywhere in the machine. The machine includes integral water treatment, dialysate preparation and extracorporeal circuit modules. The floor of the machine is constructed in a non-horizontal manner so as to provide a fluid catchment chamber with a fluid sensor. The extracorporeal circuit is mounted above the dialysate preparation module and the water treatment module. In one embodiment, a drain and drain tube allows fluid that leaks from the extracorporeal circuit module to be conducted to the floor of the machine, where the leak can be detected, along with a fluid leak in the water treatment or dialysate preparation modules. In another embodiment, a separate fluid leakage detector is placed at the base of the extracorporeal circuit module for detection of leakage in situ in the extracorporeal circuit, while the catchment chamber and sensor in the base of the machine detect leaks from the other modules.
