Claim 37:
38. A method of determining a pressure ulcer condition of a patient comprising:
acquiring patient data including body mass data that is entered into a pressure ulcer monitoring system, the system including a machine learning module;
generating, with a data processor, a pressure ulcer diagnostic function of the patient using the patient data including body mass data, a location value defined by a selected tissue pressure measurement surface location on the patient that is selected from a plurality of stored locations, and a machine learning module output, the plurality of stored locations including a heel and a shoulder;
attaching a sensor patch device to a patient at the selected tissue pressure measurement surface location with an adhesive, the sensor patch device conforming to the patient;
detecting measured pressure data with the sensor patch device having a pressure sensor with an array of pixel elements operable as one or more subarrays, a wireless transmitter, a battery and a control circuit mounted on the sensor patch device, the control circuit comprising a timer that outputs a measurement time interval (Tmeas) wherein the wireless transmitter periodically transmits pressure data from at least one subarray of pixel elements and time data in a data field including a time stamp for measured pressure data from each subarray of pixel elements and the selected tissue pressure measurement surface location, the sensor patch device attached to the patient at the tissue pressure measurement surface location on the patient to measure an accumulated pressure value during one or more time periods; and
computing a diagnostic value using the pressure ulcer diagnostic function that includes at least the measured accumulated pressure value, the body mass data, and the location value such that the diagnostic value is stored in a memory.
