1 to 4 show a pulse wave sensor at a fingertip according to an embodiment of the present invention, and FIG. 1 is a perspective view.

2 is a cross-sectional view taken along the line A-A of FIG.

3A is a perspective view of the bottom set portion of the finger tip.

3B is a front view of the surface where the nail abuts.

Claims (5)

Set bases 30, 50, 80 of the fingertips having bottom set faces 11, 31, 51, 85 of the fingertips at which the bottom of the fingertip is set The fingertips are closer to the bottom set surfaces 11, 31, 51, and 85 than the thicknesses of the standard fingertips, and the nails facing each other face 21 and 41, respectively. The sliders 20, 36, 40, and 70 provided with 72, the surfaces 21, 35, 41, and 72 where the nails abut the fingertips. The surfaces 21, 35, 41, and (1), (35), (41), (1), (35) (41) The sliders 20, 36, 40, and 70 are approached by an elastic body that imparts a substantially constant pressing force against the fluctuation of the slide stroke in accordance with the variation in the position of contact with the nail of 72). Force is applied in the direction of the finger tip The light emitting element 19 on one side of the bottom set surface 11, 31, 51, 85 and the surface 21, 35, 41, 72 where the nail abuts on the portion. And the pulse wave sensor of the fingertip, characterized in that the light receiving element 29 is disposed opposite to the other side. The method according to claim 1, wherein between the bottom 1a of the fingertip in the natural state of the finger and the first and second joints on the surfaces of the set supports 30, 50, and 80 of the fingertip. Fingers characterized in that the bottom set surface 11 of the finger tip inclined correspondingly to the standard state of the bottom and the raised surface 13 having the guide surface 12 of the edge of the finger of the finger are formed on the back surface. Pulse wave sensor at the end. The bottom set surface (11), (31), (51) of the finger tip is formed with a recess or a hole (14) avoiding the center portion (13a) of the bottom of the finger tip, A light emitting element (19), (43) or light receiving element (29), 53 is disposed behind the recess or the hole (14), pulse wave sensation at the fingertips. The fingertip pulse wave sensor according to claim 1, wherein the set supporting portions (30), (50), and (80) of the fingertips are integrally formed in the apparatus main body. The surface of the set end 110 of the finger tip is inclined in correspondence to the standard shape of the bottom of the finger tip in its natural state with respect to its bottom 110b and the bottom between the first and second joints of the finger, respectively. A raised face 113 having a bottom set face 111 at the tip of the finger and a back guide face 112 at the tip of the finger, and a standard finger with respect to the bottom set face 111 at the tip of the finger. The fingernail abutment surface 121 is provided with a slider 121 having a face 121 contacting and facing the nail than the thickness of the tip so that the finger contacting surface 121 approaches and displaces the bottom set surface 111 of the fingertip. It guides to the set base 110 of a fingertip so that it can slide in the inclined direction with respect to the bottom surface 110b, The static load spring 117 is accommodated in the inside of the ridge | surface 113, and the inner end thereof is the said slider. 120 or above hand The bearing is set to be freely rotated by the set end 110 of the lock end, and the outer end 117a thereof is connected to the set end 10 or the slider 120 of the fingertip, thereby counteracting the force. And a light emitting element 119 on one side and a light receiving element 129 on the other side of the bottom set surface 111 of the fingertip and the nail contacting surface 121. Part of the pulse wave sensor. ※ Note: The disclosure is based on the initial application.
