Publication number: 20150306336Abstract: A CPAP device for delivering pressurized, humidified breathable gas for a patient includes a flow generator configured to pressurize a flow of breathable gas. The flow generator includes an air outlet and a removable water container configured to humidify the pressurized breathable gas received from the flow generator. The water container includes an air inlet and an air outlet. The CPAP device further includes a first elastomeric face seal configured to sealingly abut against a substantially flat portion of the water container surrounding the water container air inlet, the first elastomeric face seal being located at an intermediate position between the flow generator air outlet and the water container air inlet when the water container is placed into position to pneumatically communicate with the flow generator.Type: ApplicationFiled: July 2, 2015Publication date: October 29, 2015Inventors: Perry David LITHGOW, Alexander VIRR, Duncan Lovel TREVOR-WILSON, Andrew Roderick BATH, Michael Thomas JANIAK, Dan KAO, Stephen Anthony LEA

Publication number: 20140000620Abstract: A vent assembly for use with a respiratory mask of the type used in CPAP treatment includes a porous disk portion that is attached to a biasing member such that the disk portion is maintained in a substantially sealed position against a main vent to minimize airflow through at least one side vent of the vent assembly. Debris build-up on the disk portion can cause the biasing member to deflect to provide an additional path for airflow through the at least one side vent. In another embodiment, the vent assembly can also include an anti-asphyxia feature to provide an airflow path from the environment to the user. An oxygen diverter valve may be disposed between the breathing apparatus flow generator and an oxygen injection port.Type: ApplicationFiled: September 6, 2013Publication date: January 2, 2014Applicant: ResMed LimitedInventors: Ian Malcolm SMITH, Muditha Pradeep DANTANARAYANA, Michael Thomas JANIAK
