Abstract

A system configured to provide feedback regarding fluid parameters in the skin and/or compartments of an individual to facilitate early diagnosis of skin wounds and compartment syndromes.

Claims

1. A spectrophotometric device for determining a presence of compartment syndromes comprising:

a processing device configured to receive a signal corresponding to detected electromagnetic radiation from a sensor, to calculate localized fluid parameters of a body compartment beneath a tissue site based on the received signal, and correlate the localized fluid parameters to a condition status indicative of a localized accumulation of fluid in the body compartment and a potential compartment syndrome, wherein the processing device compares the calculated fluid parameters to baseline fluid parameters specific to the body compartment and determines the condition status from the comparison.

2. The spectrophotometric device of claim 1, wherein the processing device is configured to provide the condition status to a display.

3. The spectrophotometric device of claim 2, wherein the spectrophotometric device comprises the display, wherein the display is configured to display the condition status.

4. The spectrophotometric device of claim 3, wherein the condition status comprises discrete values, wherein a first discrete value indicates a normal status, a second discrete value indicates an abnormal status, and a third discrete value indicates a severely abnormal status.

5. The spectrophotometric device of claim 3, wherein the condition status comprises a graphical representation of the condition status.

6. The spectrophotometric device of claim 1, wherein the calculated fluid parameters comprise a ratio of water of water-to-lean mass, a ratio of water-to-water, protein and fat, or a ratio of water-to-fat.

7. The spectrophotometric device of claim 1, wherein the baseline fluid parameters comprise a normal tissue fluid content of the body compartment.

8. The spectrophotometric device of claim 1, wherein the body compartment comprises an abdominal compartment or an extremity compartment.

9. A spectrophotometric device for determining a presence of skin wounds comprising:

a processing device configured to receive a signal corresponding to detected electromagnetic radiation from a sensor, to calculate localized fluid parameters based on the received signals, and correlate the localized fluid parameters to a condition status indicative of a localized accumulation of fluid in a tissue and a potential skin wound, wherein the processing device compares the calculated fluid parameters to baseline fluid parameters specific to the tissue and determines the condition status from the comparison.

10. The spectrophotometric device of claim 9, wherein the processor is configured to provide the condition status to a display.

11. The spectrophotometric device of claim 10, wherein the spectrophotometric device comprises the display, wherein the display is configured to display the condition status.

12. The spectrophotometric device of claim 11, wherein the condition status comprises discrete values, wherein a first discrete value indicates a normal status, a second discrete value indicates an abnormal status, and a third discrete value indicates a severely abnormal status.

13. The spectrophotometric device of claim 11, wherein the condition status comprises a graphical representation of the condition status.

14. The spectrophotometric device of claim 9, wherein the calculated fluid parameters comprise a ratio of water of water-to-lean mass, a ratio of water-to-water, protein and fat, or a ratio of water-to-fat.

15. The spectrophotometric device of claim 9, wherein the skin wound comprises a pressure ulcer, skin tear, venous ulcer, arterial ulcer, diabetic skin ulcer, or melanoma.

16. The spectrophotometric device of claim 9, wherein the baseline fluid parameters comprise a normal tissue fluid content of the tissue.

17. A spectrophotometric device for determining fluid parameters comprising:

a processing device configured to receive a signal corresponding to detected electromagnetic radiation from a sensor, to calculate localized fluid parameters based on the received signals, and correlate the localized fluid parameters to a condition status indicative of a potential skin wound or potential compartment syndrome, wherein the processing device compares the calculated fluid parameters to baseline fluid parameters specific to a tissue or body compartment and determines the condition status from the comparison.

18. The spectrophotometric device of claim 17, wherein the spectrophotometric device comprises a display configured to display the condition status provided by the processing device.

19. The spectrophotometric device of claim 18, wherein the condition status comprises discrete values, wherein a first discrete value indicates a normal status, a second discrete value indicates an abnormal status, and a third discrete value indicates a severely abnormal status.

20. The spectrophotometric device of claim 18, wherein the condition status comprises a graphical representation of the condition status.
