Pulse wave detecting apparatus
First Claim
1. A pulse wave detecting apparatus comprising:
- a pulse wave sensor for detecting pulse wave produced from an arterial vessel of a subject, said pulse wave sensor being movable along a cross line crossing said arterial vessel so as to be positioned in place relative to said arterial vessel, and pressed against a body surface of said subject so as to detect said pulse wave produced from said arterial vessel;
a frame member for being set on said body surface of said subject;
guide means supported by said frame member, for guiding said pulse wave sensor within a predetermined length along said cross line;
a feeding screw supported by said frame member, said feeding screw being rotatable about a longitudinal axis thereof extending parallel to said cross line, said feeding screw being threadedly engaged with said pulse wave sensor;
a drive motor supported by said frame member such that said drive motor is located adjacent to said body surface when said frame member is set on the body surface of said subject; and
a transmission device provided between said drive motor and said feeding screw, said transmitting device transmitting rotating force of said drive motor to said feeding screw, so as to move said pulse wave sensor along said cross line.
