Dialysis cassette with RFID chip

A method of sanitizing liquid for use in a medical device, the method comprising the steps of providing a medical device defining a water circuit with a volume of liquid, sensing the temperature of the volume of liquid with a sensor, heating the volume of liquid from an initial temperature to exceed a threshold temperature, maintaining the volume of liquid above the threshold temperature, determining a time-temperature value for the volume of liquid periodically once the threshold temperature has been exceeded, calculating a cumulative time-temperature value and providing an output signal once the cumulative time-temperature value has reached a level indicative of a sanitizing dose. A medical device and a liquid sanitizer are also disclosed.

Method of heat sanitization of a haemodialysis water circuit using a calculated dose

The invention provides a blood treatment device comprising: a dialyser; an inlet pump assembly; an outlet pump assembly; and a control system. The inlet pump assembly configured to deliver a first volume of dialysate from a dialysate source to the dialyser in an inlet pump cycle having a dialysate delivery stroke. The outlet pump assembly configured to remove a second volume of dialysate from the dialyser and deliver the dialysate away from the dialyser in an outlet pump cycle having a dialysate removal stroke. The control system is configured to operate the inlet pump assembly in the inlet pump cycle, and configured to operate the outlet pump assembly in the outlet pump cycle. For each inlet pump cycle there is a corresponding outlet pump cycle, and each inlet pump assembly dialysate delivery stroke has a commencement time tand a termination time h, and each outlet pump assembly dialysate removal stroke has a commencement time tand a termination time t. The blood treatment device is operable such that either: each dialysate removal stroke commencement time tis after the respective corresponding dialysate delivery stroke commencement time ti and before the respective corresponding dialysate delivery stroke termination time t; or each dialysate delivery stroke commencement time tis after the respective corresponding dialysate removal stroke commencement time tand before the respective corresponding dialysate removal stroke termination time t.
