ABSTRACT:
An infant incubator having a base (3) for supporting a premature baby; a hood (7) mounted on the base (3) to provide an incubation chamber (9) isolated from the atmosphere; a first duct (19) having a fan for circulating inner air through the incubation chamber (9); and a first heater (47) disposed on said first duct to provide a heated air; a second duct (21) branched from the first duct (19), and having a detachable humidifying vessel (15) for storing the water and combined through a shutter compartment (53) to the first duct (19) downstream of the humidifying vessel (15); a second heater (37) for heating the humidifying vessel (15); a first temperature sensor (57) to measure a chamber temperature in the incubation chamber; a second temperature sensor (39) to measure a water temperature in the humidifying vessel (15); and MPU (55) for controlling the second heater (37) based on the chamber temperature by the first temperature sensor (57) and the water temperature. The shutter compartment (53) is controlled to be moved by the predetermined amount associated with the second heater (37) being controlled to set the current water temperature to the predetermined water temperature in a lookup table, and when the vessel temperature gradually comes close to the predetermined vessel temperature, the mixing ratio is returned to the default ratio.
