In an incubator (11) according to the present invention, a single incubator (11) can be used in any state of four types of devices and thus obviates the need for having many types of devices. A canopy (27) is lowered and raised. In addition to that, a left and right treatment door (22) and a foot end treatment door (23) can be located at their highest positions, lowest positions, and intermediate positions. Also, an infrared heater (28) can be lowered and raised independently of the canopy (27). This makes it possible to switch the incubator (11) among: a state of an open type incubator a state of a closed type incubator in which the infrared heater (28) is at its highest position such that the infrared heater (28) can heat the canopy (27) and others a state of a closed type incubator in which the infrared heater (28) is at its lowest position and this incubator (11) is easily conveyable and a state of a resuscitation treatment device.
