1. A device for treating multiple medical devices that each comprise a hose and a mask, the device for treating multiple medical devices comprising:

  • a housing comprising a base, side walls extending from the base, and a cover, wherein the housing forms a gas-tight compartment when the cover is in a closed position over the side walls, and the gas-tight compartment is sized and configured to receive the multiple medical devices therein;

    a plurality of ports inside the housing, wherein each of the plurality of ports comprise a distal end configured to couple to a proximal end of a hose of a corresponding one of the multiple medical devices and a proximal end configured to receive ozone gas;

    an ultraviolet (UV) lamp attached to the cover of the compartment such that the UV lamp faces an inside of the gas-tight compartment when the cover is in the closed position, the UV lamp configured to emit UV light;

    a sensor;

    a user interface; and

    a timer;

    wherein;

    the device for treating multiple medical devices is configured to treat said multiple medical devices during an operating cycle;

    said user interface is configured to enable a user to select whether said UV lamp will turn on during said operating cycle;

    said timer is configured to determine a cycle time of said operating cycle, wherein said cycle time is a first cycle time when said UV lamp is not selected to turn on during said operating cycle, said cycle time is a second cycle time when said UV lamp is selected to turn on during said operating cycle, and the second cycle time is different than the first cycle time;

    when the device for treating multiple medical devices is in operation;

    the timer controls a release of ozone gas into said ports;

    each of the ports conveys ozone gas to an interior of the hose and mask of a respective one of the multiple medical devices, sanitizing the interior of each the multiple medical devices;

    when the UV lamp is selected to turn on during the operating cycle, the UV lamp emits UV light into the compartment so as to sanitize an outside of each of the multiple medical devices;

    the sensor senses an ozone gas level within said gas-tight compartment and generates a sensor signal indicative of a detected ozone gas level within said gas-tight compartment; and

    the user interface receives said sensor signal and provides an indicator when said ozone gas level is above a threshold ozone gas level, wherein the threshold ozone gas level is an ozone gas level that is sufficient to sterilize said multiple medical devices.
