Abstract
A breathing assistance apparatus has a main body. A humidification compartment is defined within the main body and is adapted to receive a humidification chamber. A flow generator is positioned within the main body. The flow generator and the humidification compartment are fluidly connected and a liquid containment compartment is interposed between the flow generator and the humidification compartment. The liquid containment compartment is fluidly connected to both the flow generator and the humidification compartment.
Claims18
A breathing assistance apparatus comprising:
- a main body;
- a humidification compartment defined within the main body and adapted to receive a humidification chamber;
- a flow generator positioned within the main body;
- and
- a liquid containment compartment positioned within the main body, wherein the liquid containment compartment comprises a first opening toward the humidification compartment, the liquid containment compartment being fluidly connected to both the flow generator and the humidification compartment such that a gas flow path from the flow generator to the humidification compartment passes through the liquid containment compartment,
- wherein, when the humidification chamber is received within the humidification compartment, gas passing through the first opening is configured to flow into the humidification compartment first and then from the humidification compartment into the humidification chamber, and the humidification compartment is configured to retain within the humidification compartment a volume of liquid spilled from the humidification chamber.
