[ We claim:] [1.] Method for disinfection of the hydraulic circuit of a dialysis machine, comprising an inlet for connection to an external water source and a plurality of open lines intended to be connected, in an operational configuration of the machine, to different consumable accessories, comprising the steps of:closing the open lines on the hydraulic circuit in such a way as to form a closed network of lines;bringing a reservoir containing a concentrated disinfection liquid into communication with the hydraulic circuit, in proximity to the inlet;instigating a proportional flow of water and of concentrated disinfection liquid in the hydraulic circuit in such a way as to produce a first liquid having a bactericidal action;interrupting the flow of water and of concentrated disinfection liquid when the hydraulic circuit is filled with bactericidal liquid, the initial volume of concentrated disinfection liquid in the reservoir being chosen such that at the end of the filling of the hydraulic circuit, a residual volume remains in the reservoir;adding a volume of water to the residual volume in the reservoir in order to produce a second liquid;emptying the hydraulic circuit of the bactericidal liquid;instigating simultaneously a proportional flow of water and of the second liquid in the hydraulic circuit in such a way as to produce a third liquid having a bacteriostatic action and capable of remaining in the hydraulic circuit for at least twelve hours without causing corrosion there;filling the hydraulic circuit with bacteriostatic liquid.
