Electronic blood pressure measuring device |
摘要 |
An electronic blood pressure monitor includes a cuff, a system for pressurizing the cuff, and pressure and pulse wave sensors in the cuff. In the monitor the maximum amplitude of the pulse wave is extracted and an area between the envelope lines of certain data is computed. Maximum area values are computed on the higher and lower sides of the cuff pressure corresponding to the maximum value of the pulse wave amplitude; from these area values are computed maximum and minimum blood pressure values. In another aspect, the pulse wave signal from the pulse wave sensor is separated into signal components greater and less than a reference value, these signal components are smoothed and combined and blood pressure values are determined from the combined signals and the cuff pressure values derived from the pressure sensor in the cuff.
