Abstract
An infant care center or infant care warmer having as it source of heat, an infrared emitter that is located above the infant bed and which is relatively small in dimensions so as to not impede the access to the infant by attending personnel at any time, including when X-rays are being taken to the infant. The emitter is contained in a sealed emitter assembly and includes a lens that focuses and directs the infrared radiation to a desired footprint on the infant bed. In a specific embodiment, the infrared emitter is shaped generally in the form of a parabola and a honeycomb material comprising a plurality of hexagonal openings receives the infrared radiation from the parabolic shaped emitter and redirects the radiation into a desired pattern toward the infant bed.
Claims9
An infant care center comprising:
- a standing frame member;
- a generally planar infant bed affixed to said standing frame member and adapted to underlie an infant;
- an infrared emitter mounted to said standing frame member above said infant bed, said infrared emitter comprising a ceramic base and having an emitting foil affixed thereto and adapted to radiate infrared electromagnetic radiation;
- and
- a lens system located intermediate said infrared emitter and said infant bed, said lens system receiving the infrared radiation emitted from said emitter and focusing the radiation passing through said lens system to a predetermined footprint on said infant bed to warm an infant positioned on said infant bed.
An infant care center comprising:
- a standing frame member;
- a generally planar infant bed affixed to said standing frame member and adapted to underlie an infant;
- an infrared emitter assembly mounted to said standing frame member above said infant bed, said infrared emitter assembly comprising an infrared emitter having a ceramic base and having an emitting foil affixed thereto, said infrared emitter formed into an arcuate shape to direct infrared electromagnetic radiation toward said infant bed;
- and
- a radiation shaping member located intermediate said infrared emitter and said infant bed, comprised of a plurality of elongated openings adapted to receive the infrared radiation from said arcuate shaped infrared emitter and to redirect such infrared radiation into a desired pattern toward the infant bed.
A method of providing heat to an infant positioned upon an infant bed comprising the steps of:
- locating an infrared emitter adapted to emit substantially all infrared radiation above the infant bed;
- causing the infrared emitter to emit substantially all of its infrared radiation in a path generally toward the infant bed;
- and
- modifying the path of the infrared radiation emitted by the infrared emitter by locating a radiation shaping member intermediate the infrared emitter and the infant bed having a plurality of elongated pathways through which the radiation passes to create a predetermined footprint of radiation reaching the infant bed to warm the infant.
