<p><P>PROBLEM TO BE SOLVED: To provide a sphygmomanometer apparatus and a sphygmomanometery method for improving an S/N ratio for detecting systolic pressure by effectively eliminating an influence of volume variations at the upstream part of a blood blocking air bag on a pulse wave-detecting air bag of a double-cuff method by an oscillometeric method. <P>SOLUTION: The sphygmomanometer apparatus is equipped with a main body (100) of a cuff including a cuff fabric (5), the blood blocking air bag (1), a sub air bag (3) arranged on the side of a heart, the pulse wave detecting air bag (2) for detecting pulse waves, first piping (6) connected through a first fluid resisting device (21), a check valve (22), and a second piping (7) connected through a second fluid resisting device (11), a cuff pressure detecting part (13), a pressurization control part (19) connected to a pressurizing means (18) for increasing pressure of a cuff assembly, a depressurization control part (20) for reducing pressure, a pulse wave detecting part (14) for detecting superimposed pulse waves by converting the pulse wave to detected pulse wave signals, a blood pressure detecting part (15) for determining a blood pressure value based on an output from the pulse wave detecting part and detected cuff pressure signals, and a blood pressure display part (16) for displaying blood pressure values from the blood pressure detecting part. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
