Abstract
The invention directed to an incubator for infants and includes an air guidance system which extends about the support surface 7 and effects a uniform temperature distribution. This uniform temperature distribution is achieved in that the heated air is moved via a fan 8 so that it rises between the incubator hood 2 and the inner wall 4 and thereafter descends between the inner wall 4 and the support surface 7.
Claims4
An incubator for an infant, the incubator comprising:
- a base;
- an incubator hood seated on said base and defining an enclosed space;
- a support member defining a support surface for the infant and being disposed within said enclosed space;
- an inner wall within said enclosed space arranged parallel to and in spaced relationship to said hood so as to define a first channel therewith;
- said inner wall extending peripherally around and in spaced relationship to said support member so as to define a second channel therewith;
- a blower mounted in a region below said support member for imparting movement to the air within said enclosed space;
- and,
- said inner wall being interrupted in the region of said blower and in the region above said support surface to permit air to pass through said first and second channels and circulate within said enclosed space.

A method for conducting air in an incubator for an infant, the incubator including:
- a base;
- an incubator hood seated on said base and defining an enclosed space;
- a support member defining a support surface for the infant and being disposed within said enclosed space;
- an inner wall within said enclosed space arranged parallel to and in spaced relationship to said hood so as to define a first channel therewith;
- said inner wall extending peripherally around and in spaced relationship to said support member so as to define a second channel therewith;
- the method comprising the steps of:
- providing a blower in a region below said support member and moving said air over a heater to warm the air;
- and,
- interrupting said inner wall in the region of said blower and in the region above said support surface to permit the warmed air to rise along said first channel and to then drop toward said support surface and return to said blower via said second channel.
