A system for sanitizing water in a hot tub is described. The system includes a sanitizing chamber, separate from the hot tub, and sized to hold a small portion of the water from the hot tub. A first conduit for conveys water from the hot tub to the sanitizing chamber. A second conduit conveys water from the sanitizing chamber to the hot tub. A pump is provided that moves water from the hot tub, through the first conduit into the sanitizing chamber and from the sanitizing chamber, through the second conduit, back into the hot tub. A heater heats the water in the sanitizing chamber to a temperature and for a time sufficient to destroy or deactivate undesirable microorganisms.

The present invention relates to a disinfection device of door handle being rotational and transpositional, the composition is as follows: a plurality of door handles are provided, which are respectively in the states of “to be used”, “in disinfection”, “in disinfection post-treatment” and/or “in ready”; and the door handle transposition shaft is driven by the rotary driving device of door handle transposition shaft to rotate counterclockwise, thus to complete synchronous rotation of the door handles and realize transposition operation. The use, disinfection and disinfection post-treatment of the door handles of the present invention are carried out synchronously, which can meet the requirements of immediate use of the door handles and safety to the users; the transposition of the door handles is implemented by the pure mechanical driving device; the door handles automatically rotates for transposition after a door opening and closing, therefore “disinfection after each use” is realized.

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.
