Radiant heater for infant warmers
DCFirst Claim
1. An infant care center comprising:
- a frame;
a generally planar infant bed affixed to said frame and adapted to underlie an infant;
a radiant heater affixed to said frame above said infant bed, said radiant heater comprising an infrared emitter and a reflector positioned with respect to said infrared emitter to reflect infrared radiation from said infrared emitter toward said generally planar infant bed, said reflector being formed in the geometric shape selected from the group consisting of an ellipsoid, a paraboloid and a hyperboloid, said radiant heater providing radiant energy to impinge upon said planar infant bed in a substantially uniform pattern.

Abstract
An infant care center or infant care warmer having as it source of heat, a radiant heater that includes a reflector in the shape of a quadratic surface of revolution consisting of a paraboloid, an ellipsoid or a hyperboloid. The shape allows the heater to be positioned at the head of the infant care apparatus and out of the way of the attending personnel and yet deliver sufficient heat to provide warmth to the infant. An infrared energy emitter is positioned at substantially the focal point of the geometric configuration of the reflector to provide radiant energy to be reflected toward an infant resting on a planar surface underneath the heater. While out of the way of the infant and the attending personnel, the radiant heater provides a generally uniform footprint of heat to the infant.

7. An infant care center comprising:
-
a frame;
a generally planar infant bed affixed to said frame and adapted to underlie an infant, said planar infant bed shaped as a rectangle having two long sides and two short sides;
a radiant heater affixed to said frame above said infant bed and located substantially above one of said short sides of said planar infant bed, said radiant heater comprising an infrared emitter and a reflector positioned with respect to said infrared emitter to reflect infrared radiation from said infrared emitter toward said generally planar infant bed to impinge upon said planar infant bed in a substantially uniform pattern wherein said reflector is formed in the geometric shape selected from the group consisting of an ellipsoid, a paraboloid, and a hyperboloid.

- 8. An infrared heater adapted to direct infrared radiation toward a patient, said infrared heater comprising an infrared emitter, a reflector positioned with respect to said infrared emitter to reflect infrared radiation from said infrared emitter toward a patient, said reflector being formed in the geometric shape selected from the group consisting of an ellipsoid, a paraboloid and a hyperboloid, said radiant heater providing radiant energy to impinge upon said patient in a substantially uniform pattern, said radiant heater further including a deflector mounted between said infrared emitter and a patient and adapted to reflect infrared radiation toward said reflector to be reflected by said reflector toward a patient.
-
12. A method of providing heat to a patient positioned upon a patient bed comprising the steps of:
-
providing an infrared emitter adapted to emit radiation within the infrared spectra above the patient bed; and
reflecting radiant energy emitted by the infrared emitter with a paraboloid, ellipsoid or hyperboloid shaped reflector to create a generally uniform pattern of heat on the patient bed. - View Dependent Claims (13, 14)
