摘要
FIELD: instrumentation.;SUBSTANCE: invention relates to wireless monitoring of pH in oesophagus. Follow-up system incorporates internal transmitting hardware and external registration hardware. Note here that said internal transmitting hardware comprises pH-transducer, sampling circuit, first microprocessor, power supply, first module of wireless transceiver and first means. External registration hardware comprises second microprocessor, power supply, audio signal generator, memory, data interface, button switch, second module of wireless transceiver, light state indicator, housing and second means. Second means of external registration hardware can interact with the first means. If said interaction detects that internal registration hardware is no located at the preset body part then second microprocessor initiates audio signal generator and/it light state indicator. External registration hardware, in its turn, allows intermittent detection of the intensity of signal received by second module of wireless transceiver under control of second microprocessor. If signal intensity falls beyond preset range then second microprocessor actuates audio signal generator and/or light indicator for warning purposes. Method of positioning for wireless pH monitoring is realised with the help of follow-up system.;EFFECT: ruled out invalid measurements caused by unforeseen capsule departure.;8 cl, 7 dwg
