Claim 20:
21. A method of determining a pressure ulcer condition of a patient comprising:
acquiring patient specific data for a plurality of patient condition variables including body mass data to determine a pressure ulcer condition of a patient;
entering, with a data processor, a pressure ulcer diagnostic function of the patient using the patient specific data including body mass data and a selected tissue surface location on the patient from among one or more selectable tissue surface locations wherein at least one selectable tissue surface location comprises a heel and at least one further selectable tissue surface location comprises a shoulder, the selected tissue surface location defining a location value;
detecting pressure data with a sensor patch device that is adhesively attached at the selected tissue surface location, the sensor patch device having a pressure sensor with an array of pressure sensing pixel elements, a wireless transmitter, a battery and a control circuit comprising a timer that outputs a measurement time interval (Tmeas) wherein the wireless transmitter transmits pressure data from the array of pressure sensing pixel elements and time data in a data field including a time stamp for the pressure data from each of the pressure sensing pixel elements and the selected tissue surface location, the sensor patch device attached to the patient at the selected tissue surface location on the patient such that a cumulative measured pressure value can be integrated as a function of time over one or more measurement time periods; and
automatically computing, with the data processor, a diagnostic value using the pressure ulcer diagnostic function that includes at least the cumulative measured pressure data during the one or more measurement time periods, the body mass data, and the location value.
