Patent ID: 7752002

Claim:
A calibration system for calibrating a first pressure sensor configured to output pressure measurements based on at least one calibration constant, the first pressure sensor coupled to a management device implanted into a human patient, the calibration system comprising: a pump configured to output air through an output port; a mouthpiece defining a passageway having a distal end configured for coupling with a human mouth and a proximal end configured for coupling with the output port; a second pressure sensor coupled to the passageway and configured to measure the pressure within the passageway; and a computer coupled to the pump, first pressure sensor and second pressure sensor and configured to cause the pump to output air into the passageway, and monitor pressures measured by the first pressure sensor and the second pressure sensor, wherein the computer is configured to calculate the at least one calibration constant based on the pressures measured by the first pressure sensor and the second pressure sensor and to provide the at least one calibration constant to the management device coupled to the first pressure sensor to calibrate the first pressure sensor.
