THE DEVELOPMENT OF THE FOUR-PASSAGEWAYED WIRELESS ELECTROCARDIAC MOMTOR

The Wireless four-passagewayed electrocardiac monitor is different from the conventionalmonitor.The patients,electrocardlac signal is transmitted/received in the form of radio wave.This is benefit to both the patients and the medical staff The guardianship of four patientswith one monitor at thexame time raises the guardian efficiency,This electrocardiac monitorsystem is made up of three parts:the transmitting and receiving of electrocardiac signal,theprocessing of electrocardiac signal With micro-computer.Asnong this TL084 was used to solvethe problem of high gain,higli input-rsistance and higb common-mode rejection ratio ofstage before transinission, Two;tage of frequency-moduleted transmission were used to get rid of the non-linear distortion and can hardly be disturbod. The FM receiver made up ofTDA7010T meets the demands of Simplification and;tability.The compilation of the sampleand drawing program with assembled language solves the problem of real-time speed.
