Abstract :
A light and portable-type wireless physiological signal retrieving system has always been a medical personnel´s dream. To fulfill this dream, this paper investigates a feasible method to create a wireless-type physiological signal measuring system using a PDA and the bluetooth technology. The proposed system will reduce the service costs and raise the service efficiency for current medical care systems. The waveforms and data of physiological signals, such as electrocardiograms (ECGs), phonocardiograms (PCGs), electroencephalograms (EEGs), body temperatures, and so forth, are always the vital references for medical doctors to diagnose the patients´ body condition. The traditional physiological signal measuring instruments or devices possess some shortcomings, such as high prices, bulky dimensions, ill-portability and excessive connection cables. In contrast, the proposed wireless-type physiological signal measuring system, being able to get rid of said shortcomings, holds apparent advantages in service costs and service efficiency and, hence, shall be the trend for the future. This study has completed some tests in ECG, PCG, and body temperature measurements. The proposed prototype system has successfully using the bluetooth technology to invisibly transmit and receive physical signals through the air.
