Abstract
Medical device or instrument for diagnosing pressure ulcers using optical reflectance spectroscopy. The device may comprise a tip and a controller. The tip is pressed against the skin of the patient and collects the optical reflectance data. The controller processes the data to determine whether there exists a pressure ulcer and, if there is one, its depth. The tip may also include a pressure sensor for sensing the pressure at which the tip is applied to the patient'"'"'s skin.

57. A monitoring device for use in conjunction with a subject, the monitoring device comprising:
-
a tip for pressing against tissue in a measurement region of the subject; at least one emitter to emit light energy from the tip toward the tissue of the subject; at least one photodetector to sense reflected light energy that is reflected by the tissue in the measurement region; at least one pressure sensor for sensing the pressure at which the monitoring device is applied to the tissue of the subject; and a processor-based controller in communication with the at least one photodetector, wherein the controller is programmed to monitor a condition of the subject based on input from the at least one photodetector. - View Dependent Claims (58, 59, 60, 61, 62, 63, 64, 65, 66, 67)

68. A method of diagnosing a condition of a subject, the method comprising:
-
applying a monitoring device against tissue of the subject at a first pressure level and maintaining the first pressure level within a first pressure range for a first period of time, wherein the monitoring device comprises; at least one photodetector; and at least one emitter to emit light energy from the monitoring device toward the tissue of the subject, wherein the at least one photodetector senses reflected light energy that is reflected by the tissue of the measurement region; at least one pressure sensor for sensing the pressure at which the monitoring device is applied to the tissue of the subject; and a processor-based controller in communication with the at least one photodetector; and receiving, via a user interface of the monitoring device, an indication of the condition of the subject. - View Dependent Claims (69, 70, 71, 72, 73, 74, 75)
