<p><P>PROBLEM TO BE SOLVED: To suppress the prominence of the tendon when bending the wrist and fingers, having favorable adhesion to the artery and measure precise bioinformation in a bioinformation measuring instrument. <P>SOLUTION: A cuff 2 comprises an oppression fluid bag 18 freely inflated and expanded/contracted by the supply of fluid for detecting a pulse wave signal, and two auxiliary fluid bags 19 and 20 provided outside the oppression fluid bag 18 and freely inflated and expanded/contracted by the supply of fluid. The auxiliary fluid bags 19 and 20 have double-layer structure, are communicated with the oppression fluid bag 18 via an opening part 21, and the auxiliary fluid bags 19 and 20 are mutually separated respectively. The oppression fluid bag 18 oppresses the tendon 14, the radial artery 10 and the ulnar artery 11, the auxiliary fluid bag 19 oppresses the radial artery 10, and the auxiliary fluid bag 20 oppresses the ulnar artery 11 respectively. This constitution can suppress the prominence of the tendon 14 by the bending of the wrist 5 and the fingers so as not to impede the adhesion of the oppression fluid bag 18 and the auxiliary fluid bags 19 and 20 to the wrist 5. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
