Abstract

Aspects of the present disclosure relate to a warming system. The warming system includes a light device having a light source configured to be positioned proximate to a patient support having a patient support surface. The light source can also be configured to generate infrared radiation. The warming system can also include a flexible sheet having a first side configured to reflect at least some of the generated infrared radiation from the light device toward a portion of the patient support surface.

Claims (31)

1. A warming system, comprising:

a light device having a light source, the light device configured to be positioned proximate to a patient support having a patient support surface and configured to generate infrared radiation;

a flexible sheet having a first side configured to reflect some of the generated infrared radiation from the light device toward a portion of the patient support surface, and wherein the light device comprises a housing,

a reader disposed at least partially within the housing and communicatively coupled to a computing device, the computing device comprising one or more computer processors and a memory comprising instructions that when executed by the one or more computer processors cause the one or more computer processors to:

determine one or more characteristics of the flexible sheet using the reader,

determine whether the flexible sheet is appropriate for the system based on the characteristics; and

perform at least one operation based on whether the flexible sheet is appropriate.

2. The warming system of claim 1 , wherein the light device is configured to be positioned adjacent to the patient support surface.

3. The warming system of claim 1 , wherein the light source configured to be positioned at or below a plane of the patient support surface and the light device is configured to be positioned at or below a plane of the patient support surface corresponding to a patient-facing major surface.

4. The warming system of claim 1 , further comprising a patient contact surface, wherein the patient contact surface is configured to contact the patient support surface and is attached to the light device.

5. The warming system of claim 4 , wherein the patient contact surface is configured to be removable from the patient support surface with the light device attached.

6. The warming system of claim 1 , wherein the flexible sheet has a second side opposite a first side, wherein the second side has a thermally absorptive coating disposed thereon, wherein the thermally absorptive coating is configured to absorb infrared radiation.

7. The warming system of claim 1 , wherein the flexible sheet comprises a polyester film or a nonwoven and a metalized layer disposed on the first side.

8. The warming system of claim 1 , wherein the flexible sheet comprises a thermally sensitive pigment coating configured to change between a light color and a dark color at a temperature between 37 and 43 degrees Celsius.

9. The warming system of claim 1 , wherein the flexible sheet is pleated over at least a portion thereof.

10. The warming system of claim 1 , wherein the flexible sheet comprises a set of pleat folds that form flute peaks.

11. The warming system of claim 1 , wherein the pleat fold is asymmetric.

12. The warming system of claim 1 , further comprising a light guide configured to direct light from a light device mounted on a bottom side of the patient support surface.

13. The warming system of claim 1 , wherein at least one of the one or more characteristics includes reflectivity of the flexible sheet.

14. The warming system of claim 1 , wherein whether the flexible sheet is appropriate is based on product authenticity of the flexible sheet.

15. The warming system of claim 14 , wherein the flexible sheet comprises a code readable by the reader and is indicative of product authenticity.

16. The warming system of claim 1 , wherein the at least one operation includes activating the light source.

17. The warming system of claim 1 , further comprising:

a sensor that measures physiological properties of a patient;

a computing device communicatively coupled to the sensor and comprising one or more computer processors and a memory comprising instructions that when executed by the one or more computer processors cause the one or more computer processors to:

receive the physiological property from the sensor;

determine a warming score based on the physiological property, wherein the warming score is indicative of a core body temperature of a patient;

determine whether the warming score meets a threshold;

perform at least one operation based on the warming score meeting the threshold.

18. The system of claim 17 , wherein, to perform at least one operation, the memory comprises instructions that when executed by the one or more computer processors cause the one or more computer processors to provide instructions to the light device to change from a first heat setting to a second heat setting.

19. The system of claim 18 , wherein the first heat setting includes activating a first set of bulbs for the light source and the second heat setting includes activating a second set of bulbs fewer than the first set of bulbs.
