Abstract
A device and method for monitoring the pH value of the aspirated gastric fluid of a patient includes a monitor, a sensor assembly engageable with the monitor, and a collecting reservoir engageable with the sensor assembly. The sensor assembly includes a sensor which is moveable on a base member between a cleansing cavity, calibrating cavities, and a monitoring cavity. The monitor includes a suction generating member which is connectable with the patient, and a microprocessor which is connectable with the sensor of the sensor assembly. In the operation of the device, gastric contents from the patient are aspirated by the suction generating member into the monitoring cavity. There, the sensor generates a signal indicative of the pH value of the gastric contents which is transmitted to the microprocessor. Periodically, during operation, the sensor is moved to the cleansing cavity for cleaning and subsequent calibration by successive contact with pH 7 and pH 1 solutions in the calibrations cavities of the sensor assembly.
