Abstract: A ventilator circuit for use in administering medication to a patient includes a housing, a one-way inhalation valve and a one-way exhalation valve. A metered does inhaler receptacle is in fluid flow communication with an interior space of the housing holding chamber. An exhaust conduit communicates between input and output passageways disposed on opposite sides of the interior space.

Abstract: A nasal insert includes a user interface with a housing having a circumferential wall defining an interior passage. A valve is in communication with the interior passage and limits a fluid flow through the interior passage in at least one direction. An exterior surface of the housing is adapted to interface with a nasal vestibule of a user and define an exhalation flow path. Methods of using and assembling the nasal inserts also are provided.

Abstract: A medicament dispensing device for dispensing metered dosages of a medicament includes an actuator housing having a longitudinally extending cavity and a container disposed in the cavity and having a cylinder with a first outer diameter. The cylinder is adapted to hold the medicament. The container is reciprocally moveable relative to the actuator housing along a longitudinal axis. An indicating device includes an indicator housing having a tubular portion connected to said container, with the indicating device being reciprocally moveable with the container relative to the actuator housing. The tubular portion has a second outer diameter that is of substantially the same diameter as the first outer diameter. A longitudinally extending side wall has a viewing window formed therein. An indicator is rotatably mounted in the indicator housing, with a surface thereof having indicia visible through the viewing window.

Abstract: A respiratory muscle endurance training device (RMET) includes a chamber and a patient interface. In one implementation, one or both of a CO, sensor or a temperature sensor can be coupled to the chamber or patient interface to provide the user or caregiver with indicia about the CO, level in, or the temperature of, the chamber or patient interface, and/or the duration of use of the device. In another implementation, the RMET may have a fixed volume portion adjustable to contain a measured portion of a specific patient's inspiratory volume capacity. Methods of using the device are also provided.

Abstract: A ventilator assembly includes a housing defining an inhalation interior space and an exhalation interior space separate from the inhalation interior space. A ventilator port is positioned at a first location of the housing and defines a first passageway in communication with the inhalation interior space and the exhalation interior space. A patient port is positioned at a second location of the housing and defines a second passageway in communication with the inhalation interior space and the exhalation interior space. A one-way inhalation valve permits one-way flow from the ventilator port to the patient port through the inhalation interior space and a one-way exhalation valve permits one-way flow from the patient port to the ventilator port through the exhalation interior space. A receptacle is in communication with the inhalation interior space and is operative to receive a container comprising an aerosolized medication.

Abstract: A nebulizer for efficiently and reliably delivering aerosolized fluid to an inhaling patient is disclosed. The nebulizer includes a fluid channel air inlet and fluid channel air inlet valve responsive to either a manual force external of the nebulizer, or a patient's breathing, to begin the nebulization process. Also provided is a method of providing nebulization including the steps of moving a fluid channel air inlet valve against a fluid channel air inlet so that a negative pressure may build up over the fluid in the fluid channel to draw fluid from the fluid reservoir and begin nebulization during inhalation.

Abstract: An indicating device for indicating the number of dosages of medicament dispensed from a container includes a housing, a single indicator member nested the housing, an actuator and a drive mechanism. The drive mechanism is periodically engageable with the single indicator member. The drive mechanism is operable to advance the single indicator member an incremental amount when the drive mechanism is engaged with the single indicator member. The single indicator member remains stationary and is free of engagement from the drive mechanism for at least some reciprocal movements of the actuator. A dispensing device and a dispensing system are also provided.

Abstract: A nebulizer for efficiently and reliably delivering aerosolized fluid to an inhaling patient is disclosed. The nebulizer includes a fluid channel air inlet and fluid channel air inlet valve responsive to either a manual force external of the nebulizer, or a patient's breathing, to begin the nebulization process. Also provided is a method of providing nebulization including the steps of moving a fluid channel air inlet valve against a fluid channel air inlet so that a negative pressure may build up over the fluid in the fluid channel to draw fluid from the fluid reservoir and begin nebulization during inhalation.
