Abstract: An improved infant incubator is disclosed having a cylindrical shaped transparent hood which provide considerable accessibility to the infant. The cylindrically shaped hood consists of a plurality of sections rotatable about a central axis. The sections may be individually opened to give limited access to the infant or totally rotated to a position beneath the infant support structure such that access may be had from all sides of the incubator without obstructions. Heating of the incubator compartment is achieved by a unique means of circulating heated air through a double wall construction of the hood. The air is heated in a compartment beneath the infant and the warm air enters one of the hood sections and circulates through that section whereupon it is transferred serially to the next section and eventually can be received back into the heater compartment from the hood sections for recirculation. A fan and heater are located in the heater compartment for heating and circulating the air.
