Incubator for infants
First Claim
1. An incubator for maintaining an environment for an infant, the incubator comprising:
- a base;
an incubator hood seated on said base, said incubator hood having a top wall and contiguous side walls extending upwardly from said base to said top wall so as to define a completely enclosed space therewith;
an elongated supporting member having an upper supporting surface and being mounted on said base so as to partition said enclosed space into an infant compartment above said supporting surface and an air return space below said supporting member;
said supporting member having a periphery and said supporting surface defining a peripheral region adjacent said side walls and extending around the entire periphery of said supporting member;
air supply aperture means extending along said peripheral region for passing air from said return space into said infant compartment so as to flow upwardly as an air curtain along all of said side walls in surrounding relationship to said supporting surface and the infant;
an air return channel within said enclosed space and surrounded by said walls and extending upwardly from said return space to an elevation in the vicinity of said top wall;
said air return channel having an air intake opening at said elevation for collecting and receiving the air flowing upwardly along said side walls; and
,blower means for moving the air through said air return channel and into said air return space from wherein the air can flow upwardly through said air supply aperture means.

Abstract
The invention is directed to an incubator for infants wherein air is supplied from an air supply opening arranged between the side walls of the incubator hood and the supporting member defining a supporting surface for accommodating the infant. The air flows upwardly along the side walls of the incubator hood to form an air curtain arranged in surrounding relationship to the infant. An air return channel conducts the air from the vicinity of the top wall of the incubator hood to an air return space below the supporting member. A blower moves the air through the air return channel and into the air return space from where the air can flow upwardly through the air supply opening. Because of the air curtain, there is a temperature gradient only in the vertical direction; however, in the horizontal direction, the temperature gradient is virtually zero so that all regions of the body of the infant lying on the supporting surface are warmed by air at a uniform temperature. In addition, the formation of condensate in the air return channel is prevented because the air curtain and the air return channel are completely within the space enclosed by the base of the incubator and the incubator hood mounted thereon.
