Abstract: The present disclosure relates to an apparatus that can be used to humidify a stream of air that may be delivered to a patient for respiratory assistance during Positive Airway Pressure (PAP) therapy. The apparatus includes a humidification chamber and compartment that receives the humidification chamber in which the humidification chamber is secured in the compartment to enhance thermal engagement, for example, between a heater plate of the compartment and a heater base of the humidification chamber.

Abstract: The present invention relates to an apparatus for providing respiratory assistance to a user via a user conduit. The apparatus being operable in a humidifying mode and a non-humidifying mode, and includes a humidification chamber for containing an amount of water that can be located in an operating position in the humidifying mode and, optionally separate from the apparatus in the non-humidifying mode. The apparatus may also have an auxiliary flow path that can be activated in the non-humidifying mode and a powered device that heats water in the humidification chamber when the apparatus is in the humidifying mode.

Abstract: The present disclosure relates to a positive pressure breathing circuit and a method for ventilating a patient. The breathing circuit can be used in any type of pressurized breathing therapy including, for example, continuous positive air (way) pressure (CPAP) therapy and bilevel positive air pressure therapy where the inspiratory and expiratory pressures differ.

Abstract: The invention relates to a breathing assistance apparatus that may be configured to reduce the risk of damage to electronics within the apparatus as a result of liquid leaks within the apparatus or impacts to the apparatus. In other forms, the apparatus may be configured to allow for easy assembly and/or safe operation.

Abstract: A breathing assistance apparatus that comprises a housing with inner and outer walls and an upper surface, wherein the walls and upper surface are integrally formed as a single part to avoid seams or joins between the walls to reduce the risk of damage to electronics within the apparatus as a result of liquid leaks. Also disclosed is a control system for a heating element of a humidifier which provides a secondary or back up protection mechanism to disable power to the heating element if a first electronic protection circuit does not cause the first switching member to disable power to the heating element.

Abstract: A fluid flow meter, including a fluid flow path and rotor. The rotor has at least one blade positioned in the fluid flow path. A ring is positioned upstream from, and adjacent to the rotor. The ring is adapted to condition the flow at the leading edge of the rotor blade over a range of operating conditions.

Abstract: The present invention relates to a fluid flow meter, comprising: means for defining a fluid flow path; a rotor, with at least one blade, positioned in said fluid flow path; and a ring positioned upstream from, and adjacent to, said rotor; wherein the ring is adapted to conditions the flow at the leading edge of the rotor blade over a range of operating conditions. By providing a ring the accuracy and flow measuring range may be improved.
