<p><P>PROBLEM TO BE SOLVED: To measure a blood pressure value with a simple structure with a high degree of accuracy. <P>SOLUTION: A sphygmomanometer 10a includes an arm band 12a and a body 16a. The arm band 12a includes a cylindrical housing 30, an airbag 32 provided inside the housing 30 for compressing an upper arm of a subject inserted in the inside, and a microphone 34. The microphone 34 is provided on the airbag 32 and detects oscillations by pressing the airbag against the upper arm of the subject while the airbag is pressurized by a pressurizing means 18. The body 16a includes the pressurizing means 18, a Korotkoff (K) sound filter 62 for taking out a sound component from signals measured by the microphone 34, a pulse wave filter 64 for taking out a pulse wave component, a Korotkoff part 74 for acquiring the blood pressure value by a Korotkoff method based on the sound component acquired through the K sound filter 62, and an oscillometric part 76 for acquiring the blood pressure value by an oscillometric method based on the pulse wave component acquired through the pulse wave filter 64. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
