  • Patent number: 11684736
    Abstract: Various control methods can indirectly determine incorrect connections between components in a respiratory therapy system. For example, errors in the connections can occur between a patient interface, a humidifier and/or a gases source. The methods can indirectly detect if a reverse flow condition exists or other error conditions. A reverse flow condition can occur when gases flows in a direction different from an intended direction of flow. The detection of the reverse flow condition can be indicative of likely errors in connections between the humidifier, patient interface and/or gases source.

  • Patent number: 11648367
    Abstract: A nebulizer device aerosolizes (or vaporizes) liquid drawn from a liquid reservoir via a fluid flow path into a nebulization chamber. An inlet port is coupled to an external air supply and leads through a check valve and Venturi nozzle (e.g. a duckbill valve) into the chamber to direct an air stream across an opening of the fluid flow path. A discharge port leads from the chamber to a user mask, mouthpiece or canula, where the aerosol or vapor mixture can be inhaled. A filtered outlet port isolates exhaled material from the external environment. Multiple discrete heating elements may be placed around the fluid flow path to preheat the liquid. If the liquid is sufficiently volatile, heating may vaporize the material which can condense back into an aerosol after mixing with the air stream. A set of check valves direct one-way fluid flow and prevent leakage or spillage of material from the device.

  • Patent number: 11642479
    Abstract: A respiratory system, primarily to provide a mechanical insufflation/exsufflation therapy, may include a first pressure generating source, a second pressure generating source and a primary valve to switch between insufflation/positive pressure flow and exsufflation/negative pressure flow, and to generate oscillations alongside either of these cycles. The respiratory system can optionally employ a secondary valve either on a fluidic path of the first pressure generating source or on a fluidic path of the second pressure generating source. An interfacing assembly acts as a fluidic conduit between the pressure generating sources and the patient. A control unit is configured to generate required pressurized flow and oscillations as per the user settings. The aforesaid valves can be manipulated into multiple orientations/positions, which are aligned and/or adjusted with respect to the respective pressure generating sources as per the therapy requirements.
