POSITIONING SYSTEM, APPARATUS, AND METHOD FOR WIRELESS MONITORING OF ESOPHAGEAL PH VALUE

摘要

A positioning system for esophageal PH value wireless monitoring comprises an intracorporeal sensing and emitting device (30) and an extracorporeal detecting and recording device (20). The intracorporeal sensing and emitting device (30) includes a first device (307), and the extracorporeal detecting and recording device (20) includes a second device (203). The second device (203) cooperates with the first device (307). The extracorporeal detecting and recording device (20) sends out an alarm signal under the control of a microprocessor (201) if the extracorporeal detecting and recording device (20) detects that the intracorporeal sensing and emitting device (30) moves out of specified range. The extracorporeal detecting and recording device (20) performs timed acquisition of signal intensity of a signal received by a second wireless transceiver module (204) under the control of the microprocessor (201). The extracorporeal detecting and recording device (20) sends out an alarm signal under the control of the microprocessor (201) if the extracorporeal detecting and recording device (20) detects that the signal intensity exceeds specified signal intensity range. A positioning apparatus and a method for esophageal PH value wireless monitoring are also provided.
