Breathable gas apparatus with humidifier
First Claim
1. A breathable gas supply apparatus for delivering pressurized, humidified breathable gas for a patient, the breathable gas supply apparatus comprising:
- a flow generator configured to pressurize a flow of breathable gas, the flow generator comprising an air outlet;
a removable water container configured to humidify the pressurized breathable gas received from the flow generator, the water container comprising an air inlet and an air outlet;
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;
a lid; and
a second elastomeric face seal located on the lid, a portion of the second elastomeric face seal being configured to sealingly abut against a substantially flat external surface portion of the water container surrounding the water container air outlet.

Abstract
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. In addition, the CPAP device includes a second elastomeric face seal, a portion of which is configured to sealingly abut against a substantially flat external surface portion of the water container surrounding the water container air outlet.
