| Abstract: | A method for monitoring the gastric pressure, pH, temperature and electrogastrograph is proposed. An ion-sensitive field effect transistor (ISFET) is used to detect pH,a YH-3 semiconductor diffusion piezoresistive transducer to detect the pressure, a negative temperature coefficient thermistor (NTCT)to detect the temperature,Ag/Agcl sintered biopotential electrodes to detect EGG. Three sensors for the pressure,pH and temperature respectively have been integrated on one probe. The diameter of the probe is smaller than 4 mm and the largest diameter is smaller than 8 mm after the probe is filled with air. The length of the catheter is about 1. 5m. Test results of sensor characteristics are given. All sensors are found to meet the accuracy requirements within the measuring range. They are stable and give fast dynamic response. Clinical results of four-parameter monitoring detected by the integrated sensors are given. |
