subject: You Never Worry About Your High Blood Pressure [print this page] An electronic blood pressure monitor manufacturers according to an aspect of the present invention includes a cuff configured to be mounted on a predetermined portion of a subject for pressurizing an artery of the subject, a cuff pressure controller for controlling a cuff pressure inside the cuff, a pressure detector for detecting the cuff pressure, a pulse wave detector for detecting a pulse wave of the artery that is pressurized by the cuff, and a first blood pressure measuring portion and a second blood measuring portion being selectively used by the electronic blood pressure monitor manufacturers at a time.
To practically enable exclusion of the calibrating operation means to complete calibration by the calibration unit during measurement of a blood pressure performed by a user in advance with the first blood pressure monitor manufacturers measuring portion, to be detailed. In other words, the data gathering unit gathers calibration information necessary for calibration of the second blood pressure measuring portion, that is to say, a blood pressure value calculated by the first blood pressure measuring portion at the time of blood pressure measurement, and pulse wave parameters (a characteristic amount) from one wave or several waves over a wide relative pressure range with the blood pressure value as a reference, and the data updating unit modifies values of functions corresponding to the pulse wave parameters in the function memory using the gathered relative cuff pressures and the corresponding values of the pulse wave parameters with respect to the pulse wave parameters; therefore, the user simply performs blood pressure monitor manufacturers measurement with the first blood pressure measuring portion without requiring any specific operation in addition.
Furthermore, though an SPD method is very much reduced in measuring time, a case has been encountered where a precision is not sufficient for a need of a particular user, so a necessity has been arisen for adjusting a relationship between a relative cuff pressure and a waveform characteristic amount with information showing characteristics of a pulse wave different according to an individual to calibrate a result of measurement in an application requiring a high precision. The information used for calibration of a result of measurement is hereinafter referred to as calibration information. In other words, both of electronic blood pressure monitors manufacturersof a SPD method and a prior art electronic blood pressure monitor are both operated, separately purchasing an electronic blood pressure monitor in the prior art (for example, an electronic blood pressure monitor according to an oscillometric method) for use in calibration to obtain calibration information when a precision is required, and a value of the prior art electronic blood pressure monitor, that is to say, calibration information, has to be inputted to an electronic blood pressure monitor manufacturers of an SPD method, having lead to requirement of a complicated operation.
