Abstract

An apparatus for heating an infant including an upper radiant element integrated with the hood and a lower radiant element integrated with the mattress. The upper radiant element comprises a resistive ink printed on the underside of the hood. The mattress is transparent to infra-red wave length radiant energy, and includes a temperature sensor on its topside. The hood includes a liquid crystal panel for controllably viewing the infant, whereas the rest of the hood is opaque.

Claims

1. An apparatus configured for use in a neonatal incubator comprising:

a flexible support structure being transparent to infra-red wave length radiant energy, and

a radiant element located underneath said flexible support structure and comprising a housing including a contact surface for contacting the underside of said flexible support structure, one or more radiant heating elements disposed within said housing in a location spaced from said contact surface, and an infrared radiation barrier means for blocking infrared radiation from said one or more radiant heating elements in directions away from said contact surface;

said housing incorporating infrared transmission medium between said one or more radiant heating elements and regions of said contact surface which are adjacent said infrared transmission medium, said regions of said contact surface being infrared transmissible.

2. An apparatus as claimed in claim 1 wherein said flexible support structure comprises an gas filled cushion.

3. An apparatus as claimed in claim 2 wherein said gas filled cushion is constructed from clear PVC.

4. An apparatus as claimed in claim 2 wherein said gas filled cushion is constructed from clear Polythene.

5. An apparatus as claimed in claim 1 wherein said flexible support structure comprises a gel-filled cushion.

6. An apparatus as claimed in any one of claims 1 to 3 further comprising temperature sensing means on the upper side of said flexible support structure for sensing the skin temperature of a neonate in use supported on said flexible support structure.
