A humidifier tub includes a first side having an air inlet opening configured to receive the pressurized flow of respiratory gas. A second side opposes the first side. An air outlet opening is configured to discharge the pressurized flow of respiratory gas with added humidity. An inlet passage extends from the air inlet opening toward the second side so that the pressurized flow of respiratory gas travels through the inlet passage in a first direction. A guidance structure is located between the first and second sides and positioned so that a traveling direction of the pressurized flow of respiratory gas changes from the first direction to a second direction upon the pressurized flow of respiratory gas engaging the guidance structure. The guidance structure extends downward from a lid. In addition, the first direction is a lateral direction and the second direction is a downward direction.

Humidifier tub for CPAP device

A humidifier includes a humidifier tub including an air inlet and an air outlet. The air outlet may have an exit port positioned in a plane disposed below the air inlet. A base plate is provided to the bottom of the humidifier tub. The base plate and humidifier tub define a water chamber adapted to receive a volume of water. The humidifier tub may include a guidance structure adapted to direct air entering the humidifier tub via the air inlet to swirl downwardly and around within the humidifier tub reaching the water surface before exiting the exit port. The tub may include a structure to prevent the inadvertent entry of water from the tub to the flow generator.

A humidifier includes a humidifier tub with an air inlet and an air outlet. An uppermost end of the air outlet terminates at an exit port positioned in a plane disposed below the air inlet. The air inlet is configured so that air enters the humidifier tub through the air inlet in a lateral direction. The humidifier also includes a base plate provided to a bottom of the humidifier tub. The base plate and humidifier tub define a water chamber adapted to receive a volume of liquid water. The humidifier tub further includes a guidance structure adapted to direct air entering the humidifier tub via the air inlet to swirl downwardly and around within the water chamber and into contact with the liquid water before exiting the exit port.
