<P>PROBLEM TO BE SOLVED: To provide a blood pressure measuring apparatus capable of reducing the influence of an individual difference on systolic blood pressure measurement accuracy and the influence of a measuring method including the way of winding a cuff or the like. <P>SOLUTION: The blood pressure measuring apparatus includes a cuff main body comprising an air bag for ischemia, a sub air bag for pressurizing the heart side of the blood vessel of a blood pressure measuring part and a pulse wave detection air bag for detecting pulse waves, a means for pressurizing/depressurizing the cuff main body, a cuff pressure detection means, a pulse wave detection means, and a means for displaying a blood pressure value. The blood pressure measuring apparatus has first piping connected between the pulse wave detection air bag and the pressurizing/depressurizing means, second piping connected between the air bag for ischemia and the pressurizing/depressurizing means and connected with the cuff pressure detection means through a fluid resistor, and third piping connected between the sub air bag and the pressurizing/depressurizing means through an on-off valve. When detecting the pulse waves required for blood pressure measurement in the pulse wave detection means, the on-off valve is turned to a closed state, and a series of pulse wave waveform changes that occur are obtained as pulse wave signals by the pulse wave detection means. <P>COPYRIGHT: (C)2009,JPO&INPIT |
