Abstract
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.
