In this paper is described a novel pressure Holter, which combines a microprocessor\|controlled blood pressure detecting module with a palm PC to implement remote data transfer capability. In detail, using the oscillometric method, a gas\|discharging procedure is implemented in the sleeve by controlling ON and OFF of the pump and value respectively. Meanwhile, the pressure signal in the sleeve is detected by a pressure sensor and then amplified and filtered to reject noise and to extract blood pressure oscillation wave. A/D converters digitize the pressure signals and send them to palm PC for analysis, determining the blood pressure parameters. Additional functions, such as interactive parameter setting, waveform browsing, statistics of parameters, and remote data transferring, are implemented by using the palm PC. By mean of mobile computing technology, this study has overcome the application limitation suffered by those currently available devices due to lack of remote data transfer capability. It is expected to widely apply it for acquisition of blood pressure information in many situations, including community clinic, family and hospital.
