Humidifier with a water tub within a pressurized chamber

摘要

A humidifier for humidifying a flow of breathable gas to be delivered to a patient includes a chamber configured to receive the flow of breathable gas; a tub configured to contain a supply of water, the tub being configured to be inserted into the chamber; a lid provided on the chamber and being movable between an open position and a closed position; and a seal 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 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.

1. A humidifier for humidifying a flow of breathable gas to be delivered to a patient, the humidifier comprising:
a chamber comprising a chamber outlet, the chamber configured to receive the flow of breathable gas; a tub comprising a tub lid, a tub base, an inlet and an outlet, the tub configured to contain a supply of water, the tub being configured to be removably inserted into the chamber and to direct the flow of breathable gas into the inlet; and a chamber lid provided on the chamber and being movable between an open position in which an interior of the chamber is exposed to atmosphere and a closed position in which the interior of the chamber is sealed off from atmosphere such that the chamber is pressurized when the breathable gas flows, wherein when in the closed position the chamber lid is configured to engage the tub to facilitate the formation of a seal between the tub outlet and the chamber outlet.
