Devices, systems and methods for treating multiple medical devices having passageways with ozone gas

A system for treating components of a continuous positive airway pressure (CPAP) device, comprising:

• a CPAP hose;
• a CPAP mask;
• an ozone operating system configured to generate ozone gas;
• a container comprising a plurality of walls, wherein a first wall of the plurality of walls is configured to move such that the container can transition between an open position and a closed position, the container comprising an interior that is configured to receive at least the CPAP mask therein;
• an exhaust port on the first wall;
• an oxidizing catalyst for converting ozone to oxygen, the oxidizing catalyst coupled to the exhaust port on the first wall such that the oxidizing catalyst is movable with the first wall;
• and
• an ozone port extending through a second wall of the plurality of walls of the container, such that a first end of the ozone port is disposed outside the container and a second end of the ozone port is disposed within the interior of the container;
• wherein:
• the ozone operating system is configured to fluidly couple to the first end of the ozone port and the second end of the ozone port is configured to fluidly couple to a first end of the CPAP hose, such that in operation, ozone gas generated by the ozone operating system flows into the first end of the ozone port, out of the second end of the ozone port, into an interior of the CPAP hose, out of the CPAP hose into the interior of the container, and through the exhaust port and the oxidizing catalyst.
