Pressure data acquisition assembly
First Claim
1. A pressure data acquisition assembly comprising:
- a support web for applying to a target surface of a body of an individual;
a first pressure sensor connected to the support web for sensing at a first frequency a first pressure applied to the target surface;
a calibrator in operative communication with the first pressure sensor for calibrating the first pressure sensor to a first pressure range within which the first pressure sensor senses the first pressure;
a processing element in operative communication with the first pressure sensor for receiving first pressure signals corresponding to values of the first pressure from the first pressure sensor at the first frequency, and with the calibrator for recalibrating the first pressure sensor, the processing element comprising;
a computer readable memory for storing measurement parameters comprising a first threshold value corresponding to a first threshold pressure, a first measurement time period, a first alert value, and a first change condition; and
a processor in operative communication with the computer readable memory for accessing the measurement parameters, comparing the first pressure to the first threshold pressure to provide a first comparative pressure, integrating the first comparative pressure over the first time measurement period to provide a first integrated pressure, comparing the first integrated pressure with the first alert value to determine a first alert status, comparing the first integrated pressure with the first change condition to determine a first change status, and changing at least one measurement parameter or recalibrating the first pressure sensor to a first recalibrated pressure range, according to the first change status; and
an output device in communication with the processing element for receiving signals comprising data from the processing element and displaying the data.

Abstract
A method and assembly for acquiring pressure data. A pressure sensor is applied to a target surface on an individual. A calibrator and a processing element are in communication with the pressure sensor. Processing element receives pressure data and provides an integrated pressure value over a measurement time period. The integrated pressure value is compared to an alert value and to a change condition value. Where an alert value is exceeded, an alert is transmitted to an output device for display. Where a change condition value is exceeded, a measurement parameter of the pressure sensor is changed, or the calibrator is applied to the pressure sensor to recalibrate the pressure sensor to a recalibrated pressure range.
