Abstract

A patch may be adapted for placement proximate to a surface region of a mammal. The patch may include an infrared target for receiving thermal energy from the surface region and for emitting infrared radiation according to a substantially known emissivity property. When the target is placed proximate to the surface region, the characteristics of infrared radiation emitted by the target substantially correspond to the temperature of the surface region. The patch may have means for selectively maintaining the target in a position proximate to a surface region of a mammal. The patch may include indicia uniquely associated with the patch.

Claims

1. A patch adapted for placement proximate to a surface region of a mammal, the patch comprising:

an infrared target for receiving thermal energy from the surface region and for emitting infrared radiation according to a substantially known emissivity property whereby, when the target is placed proximate to the surface region, the characteristics of infrared radiation emitted by the target substantially correspond to the temperature of the surface region;

means for selectively maintaining the target in a position proximate to the surface region of the mammal; and

indicia uniquely associated with the patch.

2. The patch according to claim 1 wherein the indicia is essentially visible to a human eye.

3. The patch according to claim 1 wherein the indicia is essentially invisible to a human eye.

4. The patch according to claim 1 wherein the indicia is selected from the group consisting of a bar code or other pattern adapted to be recognized by a machine, an RFID device, a photodiode, a magnetic medium, and physical deformation of a portion of the patch.

5. The patch according to claim 1 wherein the patch includes a bio-reactive agent having a characteristic that is configured to be detectively altered in the presence of a pre-selected bio-chemical property of the surface region.

6. The patch according to claim 5 wherein the property is essentially the pH value of the surface region.

7. The patch according to claim 5 wherein the bio-reactive agent characteristic is configured to be altered in a manner detectable through spectroscopy.

8. The patch according to claim 1 further including indicia uniquely associated with a particular location on the mammal where the patch is to be placed.

9. The patch according to claim 1 wherein the target is flexible so as to permit the patch to adapt and conform to the contour of the surface region.

10. The patch according to claim 1 wherein the target and the maintaining means are adapted to be disposable and are fashioned of essentially biodegradable materials.

11. A patch adapted for placement proximate to a surface region of a mammal, the patch comprising:

an infrared target for receiving thermal energy from the surface region and for emitting infrared radiation according to a substantially known emissivity property whereby, when the target is placed proximate to the surface region, the characteristics of infrared radiation emitted by the target substantially correspond to the temperature of the surface region; and

indicia uniquely associated with said patch.

12. The patch according to claim 11 wherein the indicia is essentially visible to a human eye.

13. The patch according to claim 11 wherein the indicia is essentially invisible to a human eye.

14. The patch according to claim 11 wherein the indicia is selected from the group consisting of a bar code or other pattern adapted to be recognized by a machine, an RFID device, a photodiode, a magnetic medium, and physical deformation of a portion of the patch.

15. The patch according to claim 11 wherein the patch includes a bio-reactive agent having a characteristic that is configured to be detectively altered in the presence of a pre-selected bio-chemical property of the surface region.

16. The patch according to claim 15 wherein the property is essentially the pH value of the surface region.

17. The patch according to claim 15 wherein the bio-reactive agent characteristic is configured to be altered in a manner detectable through spectroscopy.

18. The patch according to claim 11 further including indicia uniquely associated with a particular location on the mammal where the patch is to be placed.

19. The patch according to claim 11 wherein the target is flexible so as to permit the patch to adapt and conform to the contour of the surface region.

20. The patch according to claim 11 wherein the target is adapted to be disposable and is fashioned of essentially biodegradable material.
