摘要： The present invention relates to an elbow assembly for use with a patient interface during respiratory therapy of a patient with a therapy flow of gas pressurized above ambient pressure. The elbow assembly provides a vent flow of gas to discharge gas exhaled by the patient from a pressurized volume within the elbow assembly. The vent flow is continuous during the respiratory therapy. The elbow assembly comprises an elbow having a first end configured to be connected to an air delivery tube and a second end opposite the first end; and a vent housing connected to the second end and comprising a base having a plurality of inner orifices extending through the base and configured to allow gas to be discharged to atmosphere from the pressurized volume and a plurality of outer orifices positioned radially outward of the plurality of inner orifices, extending through the base, and configured to allow gas to be discharged to atmosphere from the pressurized volume. The elbow assembly further comprises a membrane constructed from an elastically deformable material, the membrane being positioned parallel and adjacent to the base, in an undeformed state, to allow a first portion of the vent flow to discharge to atmosphere through the plurality of inner orifices and a second portion of the vent flow to discharge to atmosphere through the plurality of outer orifices throughout a therapeutic pressure range. The membrane is elastically deformable due to pressure within the pressurized volume to apportion the first portion of the vent flow and the second portion of the vent flow between the plurality of inner orifices and the plurality of outer orifices, respectively, depending on the pressure within the pressurized volume throughout the therapeutic pressure range.

摘要： The present invention relates to a reservoir (5110) configured to hold a predetermined maximum volume of water, comprising a plurality of walls forming a cavity, a base (5112) structured to hold the predetermined maximum volume of water, and a lid (5114) structured to connect to the base to allow the reservoir to be convertible between an open configuration and a closed configuration. The reservoir further comprises an inlet tube (5124) configured to deliver a flow of air into the cavity, the inlet tube having an inlet tube interior end (5125) and an inlet tube exterior end, and an outlet tube (5126) configured to deliver a humidified flow of air from the cavity, the outlet tube having an outlet tube interior end (5127) and an outlet tube exterior end. The inlet tube interior end and the outlet tube interior end are located within the cavity and the inlet tube exterior end and the outlet tube exterior end are located in one of the plurality of walls of the cavity. A first axis is defined by the inlet tube interior end and the inlet tube exterior end. When the reservoir is tilted approximately 90° to normal working orientation, the first axis is on a first angle such that the inlet tube interior end and the inlet tube exterior end are positioned at different heights, such that a level of the predetermined maximum volume of water is below at least one of the inlet tube interior end or the inlet tube exterior end to prevent spillback of water through the inlet tube.

摘要： The present invention relates to a water reservoir (5110) for use with a respiratory pressure therapy (RPT) device (4000) for pressurising breathable air to treat a respiratory disorder in a patient. The water reservoir comprises a reservoir base (5112) configured to hold a volume of water to be used for humidification of the breathable air, a reservoir lid (5114) movably connectable to the reservoir base to allow the water reservoir to be converted between an open configuration and a closed configuration, a reservoir inlet (5118) and a reservoir outlet (5122) as well as an intermediate portion (5202) comprising a carrier (5117) and a resilient portion (5116). The intermediate portion is releasably engaged with the reservoir lid or the reservoir base, wherein the resilient portion forms a seal between the reservoir base and the reservoir lid when the reservoir is in the closed configuration. Furthermore, the intermediate portion comprises a flow director (5195) configured and arranged to redirect at least a portion of a flow of air entering the water reservoir from the reservoir inlet.

The water reservoir includes a base portion (5112) configured to hold a volume of water and a lid portion (5114) comprising an inlet (5118) and an outlet (5122). The lid portion is pivotably connected to the base portion to allow the water reservoir to be convertible between an open and a closed configuration. The water reservoir comprises a rotation guide (5220) and a rotation stop (5222) to define a range of rotation of the lid portion, wherein one end of the range of rotation is defined by the water reservoir being in the closed configuration and wherein the other end of the range of rotation is defined by a fully open position of the water reservoir. The rotation guide interferes with the rotation stop at the fully open position.

摘要： The present invention relates to a respiratory pressure therapy device (4000) comprising an integrated humidifier (5000). The integrated humidifier comprises a blower (4142) for producing a flow of air at positive pressure and a water reservoir (5110) configured to contain a volume of water for humidifying a pressurised flow of air. The water reservoir comprises a base portion (5112), a lid portion (5114) comprising an inlet (5118) and an outlet (5122), and a compliant portion (5116) constructed from an elastomeric material. The base portion and the lid portion are pivotably engaged and configurable in an open configuration and a closed configuration while pivotably engaged, and the compliant portion acts as a seal between the base portion and the lid portion when the reservoir is in the closed configuration. The water reservoir further comprises a water reservoir dock (5130) comprising a cavity (5160) configured to retain a portion of the reservoir therein. The water reservoir lid includes a protrusion (5142) and the water reservoir dock includes a recess (5144), the protrusion being adapted to removably engage with the recess when the water reservoir is inserted into the water reservoir dock to secure the water reservoir relative to the water reservoir dock.
