Dialysis machine with leakage detection

A dialysis machine comprising:

• a water treatment module filtering incoming water;
• an extracorporeal blood circuit module for receiving blood from a patient, circulating the blood to a dialyzer and returning the blood to the patient, said dialyzer comprising a blood side and a dialysate side;
• a dialysate preparation module receiving water from said water treatment module and mixing said water with dialysate chemicals to form a dialysate solution, said dialysate preparation module further comprising a dialysate circuit conducting said dialysate solution to said dialysate side of said dialyzer;
• and
• a floor for said machine with said water treatment module and dialysate preparation module placed above said floor in said machine, the improvement comprising:
• said extracorporeal blood circuit module placed in a housing above said dialysate preparation module and said water treatment module and a drain in the base of said extracorporeal blood circuit module for conducting fluid leaking in said extracorporeal blood circuit module to said floor of said machine, said floor constructed in an non-horizontal manner so as to cause fluid falling on said floor from a leak in said water treatment module, extracorporeal blood circuit module or said dialysate preparation module to move to an extreme lowermost portion of said floor, said floor farther comprising a fluid sensor disposed in the region of said extreme lowermost portion of said floor, said fluid sensor detecting the presence of fluid leaking from said water treatment module, dialysate preparation module or extracorporeal blood circuit module.
