摘要

A CPAP device includes a humidifier including humidifier tub having a heat conducting base plate; and a cradle to support the humidifier tub in an operative position. The cradle may also support a flow generator in operative relation to the humidifier tub. The cradle includes a heater plate in communication with the heat conducting base plate of the humidifier tub in use. The cradle further includes a retaining mechanism to retain the humidifier tub in the cradle, the retaining mechanism being structured to force the base plate into engagement with the heater plate.
