Abstract
A humidification device (10) for use with a CPAP unit (18) or similar breathing device is provided which includes a stationary cabinet (12) with a slide-type drawer member (14) adapted to hold a supply of humidifying water. The cabinet (12) includes an input (28) and an output (30) allowing connection of CPAP device conduits (100, 102) respectively for delivering air to the humidifying device (10), and for delivering humidified output air to a patient. Use of the sliding drawer member (14) facilitates filling of the device (10) with water and periodic cleanup thereof. In alternate embodiments, electrical resistance heaters (84, 86) are secured to the drawer member (14). Mating electrical connectors (42, 94) respectively mounted on the cabinet (12) and drawer member (14) provide electrical power to the heaters for water heating purposes.
