## Abstract

An infant care device and, more particularly an apparatus for providing the combined functions of an infant incubator and a radiant infant warmer and which includes a radiant heater assembly contained within a housing and mechanisms and methods to quickly reduce the heating from the radiant heater assembly when the infant care device is quickly converted from an open infant radiant warming device to an enclosed incubator.

## Claims

### Claim 1

An infant care apparatus that can convert from an open radiant warmer configuration to an enclosed incubator configuration, the infant care apparatus comprising:
a mattress on a base support surface;
clear sidewalls with an open top surrounding said mattress;
a vertical member extending upwardly from said surface; and
a canopy containing a radiant heater assembly mounted to said vertical member, the canopy being movable along said vertical member between (i) an upper open radiant warmer position above said surface and (ii) a lower incubator position in which the canopy is positioned on the top of the clear sidewalls forming a closed incubator;
wherein said radiant heater assembly comprises (i) a radiant heater element extending through an opening in a radiant heater reflector that directs heat downward toward the mattress and (ii) a radiant heater deflector surrounding a lower end of the radiant heater element for deflecting heat from the radiant heater onto the radiant heater reflector and down toward the mattress;
wherein when the canopy is in the upper open radiant warmer position, said radiant heater element extends outwardly from the opening in the radiant heater reflector toward the mattress, in order to effectively radiate heat downward toward the mattress; and
wherein, when the canopy is in the lower incubator position, said radiant heater element is retracted through the opening in the radiant heater reflector away from the mattress.

### Claim 2 (depends on 1)

The infant care apparatus that can convert from an open radiant warmer configuration to an enclosed incubator configuration of claim 1, wherein movement of the canopy between the upper open radiant warmer position above said surface and the lower incubator position in which the canopy is positioned on the top of the clear sidewalls is programmed and powered to occur automatically when requested by a user.

### Claim 3 (depends on 2)

The infant care apparatus that can convert from an open radiant warmer configuration to an enclosed incubator configuration of claim 2, wherein the radiant heater element is programmed and powered to automatically retract when the infant care apparatus converts from the open radiant warmer configuration to the enclosed incubator configuration.

### Claim 4

An infant care apparatus that can convert from an open radiant warmer configuration to an enclosed incubator configuration, the infant care apparatus comprising:
a mattress on a base support surface;
clear sidewalls with an open top surrounding said mattress;
a vertical member extending upwardly from said surface; and
a canopy containing a radiant heater assembly mounted to said vertical member, the canopy being movable along said vertical member between (i) an upper open radiant warmer position above said surface and (ii) a lower incubator position in which the canopy is positioned on the top of the clear sidewalls forming a closed incubator;
wherein said radiant heater assembly comprises (i) a radiant heater element extending through an opening in a radiant heater reflector that directs heat downward toward the mattress and (ii) a radiant heater deflector surrounding a lower end of the radiant heater element for deflecting heat from the radiant heater onto the radiant heater reflector and down toward the mattress;
wherein, when the canopy is in the upper open radiant warmer position, said radiant heater element extends outwardly from the opening in the radiant heater reflector toward the mattress, in order to effectively radiate heat downward toward the mattress; and
wherein, when the canopy is in the lower incubator position, said radiant heater element is retracted by degrees through the opening in the radiant heater reflector to defocus the heating effect of the radiant heater element and effectively achieve reduced heating of the mattress in the enclosed incubator configuration.

### Claim 5 (depends on 4)

The infant care apparatus that can convert from an open radiant warmer configuration to an enclosed incubator configuration of claim 4, wherein movement of the canopy between the upper open radiant warmer position above said surface and the lower incubator position in which the canopy is positioned on the top of the clear sidewalls is programmed and powered to occur automatically when requested by a user.

### Claim 6 (depends on 5)

The infant care apparatus that can convert from an open radiant warmer configuration to an enclosed incubator configuration of claim 5, wherein the retraction of the radiant heater element by degrees to defocus the heating effect of the radiant heater element is automated using temperature feedback from the incubator to adjust the degree of defocusing automatically.
