A humidifier includes a heating element including a porous structure of electrically resistive and thermally conductive material configured to substantially vaporise liquid that is passed through the porous structure. The porous structure has a liquid inlet and a vapour outlet. The humidifier further includes an outer housing surrounding at least a portion of the porous structure for containing the liquid and vapour within the porous structure. The porous structure includes a first electrical connector and a second electrical connector, the first and second connectors being configured for receiving electrical power and applying a voltage across the porous structure to generate heat.

A humidifier (14) for humidifying a flow of breathable gas to be delivered to a patient includes a chamber (16) configured to receive the flow of breathable gas; a tub (20) configured to contain a supply of water, the tub being configured to be inserted into the chamber; a lid (18) provided on the chamber and being movable between an open position and a closed position; and a seal (19) provided on the lid, the seal being configured to seal the chamber such that the flow of breathable gas pressurizes the chamber. The humidifier may be connectable to a flow generator (12) configured to generate the flow of breathable gas. A tube for delivering the humidified flow may be connected to the humidifier. The tube may be a heated or non-heated tube. A respiratory apparatus for delivering a flow of breathable gas to a patient may include the humidifier and the flow generator and/or the tube. A method of humidifying a flow of breathable gas comprises sealing a chamber containing a supplying a water and pressurizing the chamber by directing the flow of breathable gas into the chamber.

摘要:
A respiratory treatment apparatus provides respiratory treatment with improved power management control to permit more efficient power consumption and power supply units, such as battery powered operation. In one embodiment, power management prioritizes the flow generator (104) over other accessories such as the heating elements (111, 135) of a humidifier (112) and/or a delivery tube. The flow generator may control operations of the heating elements as a function of a detected respiratory cycle. For example, the timing of operation of the heating elements may be interleaved with the portion of an inspiratory phase of the respiratory cycle to permit the flow generator to operate during a peak power operation without a power drain or with a lower power drain from these components. Operations of distinct sets of components of the system (e.g., different heating elements) may also be interleaved to prevent simultaneous peak power operations.
