Technologies for sanitizing/disinfecting medical devices

A sanitization system, comprising:

• a base comprising:
• a sanitizing chamber configured to receive a continuous positive airway pressure (CPAP) mask;
• an ozone gas outlet disposed on an exterior surface of said base;
• a receptacle disposed on said exterior surface of said base, said receptacle configured to form a seal with a CPAP hose such that at least a portion of said CPAP hose is disposed outside of the sanitizing chamber;
• an exhaust port fluidly coupled to said sanitizing chamber;
• and
• a filter fluidly coupled to said exhaust port, said filter configured to convert said ozone gas to breathable gas;
• a sanitizing gas generator configured to supply ozone gas to said ozone gas outlet, wherein said ozone gas outlet is configured to be fluidly coupled to a first end of said CPAP hose, the first end of said CPAP hose disposed outside of the sanitizing chamber;
• a primary fan or pump configured to push or draw at least a portion of said ozone gas from the sanitizing gas generator, through said first end of said CPAP hose, through a second end of said CPAP hose, and into the sanitizing chamber;
• and
• a secondary fan or pump configured to push or draw at least a portion of said ozone gas from the sanitizing chamber through the exhaust port;
• and
• a controller configured to cause the sanitization system to perform a sanitization operation on said CPAP mask and an inside of said CPAP hose, wherein said sanitizing operation comprises:
• performing a plurality of disinfection cycles, each of said plurality of disinfection cycles comprising:
• during a pulse period, simultaneously supplying said ozone gas with said sanitizing gas generator while operating both said primary fan or pump and said secondary fan or pump to cause said ozone gas flow towards said filter;
• and
• conducting a dwell operation after the pulse period, the dwell operation comprising discontinuing supply of said ozone gas while operating at least one of said primary fan or pump and said secondary fan or pump for a dwell time to cause said ozone gas flow towards said filter;
• and
• after performing said plurality of disinfection cycles, performing a purge to convert ozone gas within said sanitizing system to breathable gas.

A method of sanitizing a continuous positive airway pressure (CPAP) hose and a CPAP mask with a sanitization system comprising a base including a sanitizing chamber configured to receive the CPAP mask, an ozone gas outlet disposed on an exterior surface of the base, a receptacle disposed on the exterior surface of the base and configured to form a seal with the CPAP hose such that at least a portion of the CPAP hose is disposed outside of the sanitizing chamber, an exhaust port fluidly coupled to the sanitizing chamber, a filter fluidly coupled to the exhaust port and configured to convert the ozone gas to breathable gas, a sanitizing gas generator, a primary fan or pump, a secondary fan or pump, and a controller, the method comprising:

• with the controller:
• causing the sanitization system to perform a sanitizing operation on the CPAP mask and an inside of the CPAP hose, the sanitizing operation comprising:
• performing a plurality of disinfection cycles, each of said plurality of disinfection cycles comprising:
• during a pulse period, simultaneously supplying ozone gas with said sanitizing gas generating while operating both the primary fan or pump and the secondary fan or pump to cause said ozone gas flow towards the filter;
• and
• conducting a dwell operation after the pulse period, the dwell operation comprising discontinuing supply of said ozone gas while operating at least one of said primary fan or pump and said secondary fan or pump for a dwell time to cause the ozone gas flow towards the filter;
• and
• performing a purge to convert ozone gas within said sanitizing system to breathable gas.
