SPHYGMOMETRIC ELECTRODE UNIT AND SPHYGMOMETER

摘要

PPROBLEM TO BE SOLVED: To provide a sphygmometric electrode unit enabling a highly precise volumetric sphygmometry in a simple constitution. PSOLUTION: This sphygmometric electrode unit 10A is provided with an electrode group EG including a pair of current applying electrodes 20A and 30A and a pair of voltage metering electrodes 20B and 30B, and a support member 12 for supporting the electrode group EG. The electrode group EG includes a first electrode unit 20 having a first current applying electrode 20A and a first voltage metering electrode 20B, and a second electrode unit 30 positioned at a spacing from the first electrode unit 20 and having the second current applying electrode 30A and the second voltage metering electrode 30B. The support member 12 supports the electrode group EG so that those electrodes 20A, 20B, 30A and 30B may be arranged in an extending direction of an artery 510 with the faces of the electrodes 20A, 20B, 30A and 30B to contact a living body being arranged substantially flush with each other, and with the sphygmometric electrode unit 10A being mounted on the living body.
