Not only the dialysis machine, but also its outer supply conduits and connection tubes together with the associated water distribution system can be flushed and disinfected in the present disinfection method by including these members in the cleaning circuit. Energy is saved and the amount of disinfectants is reduced during hot cleaning and chemical disinfection in a recirculatory process, and the duration of the disinfecting operations can moreover be decreased. Furthermore, a five-valve assembly is provided in or on the dialysis apparatus, in an additional apparatus with respect to the dialysis apparatus or in a water supply system integrated into the wall of a dialysis station for the dialysis apparatus so as to carry out the disinfection method, and a supply means is provided for introducing the disinfectant into the recirculatory circuit.
An apparatus for flushing a dialysis machine having an inlet and an outlet and wherein water is provided from an an external water supply and is circulated through the machine and into a drain, said apparatus comprising:
A dialysis apparatus having an internal fluid flow circuit having an inlet and outlet and an external water supply having a water inlet conduit and water outlet conduit connected to the inlet and outlet of said apparatus, said apparatus comprising a pair of spaced on-off valves on each of a water inlet and water outlet conduits, a transverse conduit connected between the water inlet and water outlet conduits and between the respective pairs of valves, said valves being operable to provide a first outer circuit to circulate water from said water inlet conduit and outlet conduit through said transverse conduit, and a second circuit to circulate water through an internal fluid flow circuit of a dialysis apparatus.
A method for disinfecting a dialysis apparatus, wherein the apparatus comprises an internal liquid flow circuit having an inlet and an outlet, said method comprising:
