Abstract

A warming device configured to warm an infant. The warming device includes a base that supports the infant and an overhead portion that includes an enclosure. An arm is coupled to the base and to the overhead portion. The arm supports the overhead portion above the base. A heating element is operated to generate heat to warm the infant. The overhead portion includes the heating element. A portion of the heat is dissipated into the overhead portion as a waste heat. A warming blanket has a stored state and a deployed state. In the stored state, the warming blanket is at least partially inside the overhead portion. In the deployed state, the warming blanket is outside the overhead portion. The warming blanket is designed to store the waste heat when the warming blanket is in the stored state and to warm the infant when in the deployed state.

First claim

We claim:

1. A warming device configured to warm an infant, the warming device comprising:
a base configured to support the infant;
an overhead portion that includes an enclosure;
an arm coupled to the base and to the overhead portion, wherein the arm supports the overhead portion above the base;

a heating element configured to generate a heat to warm the infant, wherein the overhead portion includes the heating element, and wherein a portion of the heat is dissipated into the overhead portion as a waste heat; and
a warming blanket having a stored state and a deployed state, wherein in the stored state the warming blanket is at least partially inside the overhead portion, wherein in the deployed state the warming blanket is outside the overhead portion, wherein the warming blanket is configured to store the waste heat when the warming blanket is in the stored state, and wherein the warming blanket is configured to warm the infant when in the deployed state.

2. The warming device according to claim 1 , further comprising a door in the overhead portion that opens and closes to provide access inside the overhead portion.

3. The warming device according to claim 2 , further comprising a window in the overhead portion such that the warming blanket is viewable outside the overhead portion while the door is closed.

4. The warming device according to claim 1 , wherein the overhead portion further comprises a reflector having an upper portion and a lower portion, wherein the upper portion faces the enclosure, wherein the lower portion faces the base, and wherein the heating element is between the upper portion and the base such that the upper portion of the reflector directs the heat generated by the heating element towards the base.

5. The warming device according to claim 4 , wherein in the stored state the warming blanket is between the reflector and the enclosure.

6. The warming device according to claim 5 , further comprising an insulator that is between the reflector and the enclosure, wherein in the stored state the warming blanket is between the insulator and the enclosure, and wherein the insulator reduces the waste heat that is dissipated from the reflector to the overhead portion.

7. The warming device according to claim 1 , wherein the warming blanket further comprises a temperature sensor that measures a temperature of the warming blanket.

8. The warming device according to claim 7 , wherein the warming blanket further comprises a display that indicates the temperature measured by the temperature sensor.

9. The warming device according to claim 1 , wherein the warming blanket further comprises a first edge, a second edge that is opposite the first edge, and a fastener configured to removably couple the first edge to the second edge, wherein the warming blanket is configured to be wrapped around the infant, and wherein the fastener is configured to retain the warming blanket around the infant when the fastener is fastened.

10. The warming device according to claim 1 , wherein the warming blanket includes a phase change material configured to store at least a portion of the waste heat.

11. A method for warming an infant, the method comprising:
providing a base configured to support the infant;
providing an overhead portion that includes an enclosure;

supporting the overhead portion above the base with an arm, wherein the arm is coupled to the base and to the overhead portion;
providing a heating element within the overhead portion, wherein the heating element is configured to generate heat to warm the infant, and wherein a portion of the heat is dissipated into the overhead portion as a waste heat; and
providing a warming blanket that is positionable in a stored state and in a deployed state, wherein in the stored state the warming blanket is at least partially inside the overhead portion, wherein in the deployed state the warming blanket is outside the overhead portion, wherein the warming blanket is configured to store at least a portion of the waste heat when the warming blanket is in the stored state, and wherein the warming blanket is configured to warm the infant with the waste heat stored from the heating element when in the deployed state.

12. The method according to claim 11 , further comprising providing a door in the overhead portion that opens and closes to provide access inside the overhead portion.

13. The method according to claim 12 , further comprising providing a window in the overhead portion such that the warming blanket is viewable outside the overhead portion while the door is closed.

14. The method according to claim 11 , wherein the overhead portion further includes a reflector having an upper portion and lower portion, further comprising configuring the reflector such that the upper portion faces the enclosure and the lower portion faces the base, and further comprising positioning the heating element between the upper portion and the base such that the reflector directs the heat generated by the heating element towards the base.

15. The method according to claim 14 , wherein in the stored state the warming blanket is between the reflector and the enclosure.

16. The method according to claim 15 , further comprising positioning an insulator between the reflector and the enclosure, wherein in the stored state the warming blanket is between the insulator and the enclosure, and wherein the insulator reduces the waste heat that is dissipated from the reflector to the overhead portion.

17. The method according to claim 11 , further comprising providing a temperature sensor with the warming blanket and measuring with the temperature sensor a temperature of the warming blanket.

18. The method according to claim 17 , further comprising providing a display with the warming blanket that indicates the temperature measured by the temperature sensor.

19. The method according to claim 11 , wherein the warming blanket further comprises a first edge and a second edge that is opposite the first edge, further comprising providing a fastener configured to removably couple the first edge to the second edge, and further comprising fastening the first edge to the second edge to retain the warming blanket around the infant.

20. The method according to claim 11 , further comprising fabricating the warming blanket to include a phase change material configured to store at least a portion of the waste heat.
