Abstract: A respiratory assistance apparatus includes a flow generator and a humidifier. The humidifier includes a humidification chamber. The humidification chamber comprises a water tub that is configured to receive a volume of water. A lid is hingedly coupled to the water tub for enclosing a volume contained within the water tub.

Abstract: A breathing assistance apparatus has a lid and latch assembly configured for one-handed operation. The apparatus also includes a hinge assembly that separates when over-rotated but that reengages upon closing of the lid onto the main body of the apparatus.

Abstract: The operational parameters of a respiratory apparatus can be controlled through the use of a user interface located on a separate or separable mobile computing device. Sensors or features located on the mobile computing apparatus can be used to adjust the operation parameters or therapy of the respiratory apparatus or otherwise improve the compliance of a patient utilizing the respiratory apparatus.

Abstract: A pressure regulating or pressure relief device comprises an inlet and an outlet chamber with an outlet. The inlet is in fluid communication with the outlet chamber. A valve seat is located between the inlet and the outlet. A valve member is biased to seal against the valve seat, and displaces from the valve seat by an inlet pressure at the inlet increasing above a pressure threshold to allow a flow of gases from the inlet to the outlet via the outlet chamber. The flow of gases through the outlet causes an outlet pressure in the outlet chamber to act on the valve member together with the inlet pressure to displace the valve member from the valve seat.

Abstract: The invention relates to a pressure relief valve comprising a respiratory system muffler located along a gas flow path of the pressure relief valve. The muffler comprises a tortuous gas flow path to attenuate sound. The invention also relates to a respiratory system muffler comprising a gas flow path extending between an inlet and an outlet of the muffler. The gas flow path has a variable cross-sectional area and comprises one or more expansion portions comprising a first cross-sectional area and one or more contraction portions comprising a second cross-sectional area. The first cross-sectional area is generally larger than the second cross-sectional area. The variable cross-sectional areas of the gas flow path help to attenuate sound.

Abstract: A connector having a connector body with an inlet and an outlet defining a gas flow passage therebetween. The connector body has an overlap portion that is configured to overlap with a portion of a second connector when connected. An access passage extends through the overlap portion to the gas flow passage.
