Pulse wave detecting apparatus
First Claim
1. A pulse wave detecting apparatus for detecting a blood pressure pulse wave of an arterial vessel of a subject, based on an oscillatory motion of at least one contact element which is adapted to be depressed against a surface of a body member of the subject, such that said at least one contact element is oscillated in response to the pulsation of the arterial vessel, said detecting apparatus comprising:
- a main frame for supporting said at least one contact element such that said at least one contact element is movable relative to said main frame, said main frame being attached to said surface of the body member;
positioning means operable at least for moving said at least one contact element relative to and along said surface, in a direction perpendicular to a direction of extension of said arterial vessel, to thereby locate one of said at least one contact element right above said arterial vessel; and
pressing means for moving said at least one contact element relative to said main frame, in a direction toward said surface, for forcing said at least one contact element against said surface.

Abstract
A pulse wave detecting apparatus for detecting a blood pressure pulse wave of an arterial vessel of a subject, based on an oscillatory motion of at least one contact element which is adapted to be depressed against a surface of a body member of the subject, such that each contact element is iscillated in response to the pulsation of the arterial vessel. The apparatus includes a main frame for supporting each contact element such that the contact element is movable relative to the main frame fixed in position on the surface of the body member. A positioning device is provided, which is capable of at least moving the contact element relative to and along the body surface, in a direction perpendicular to the arterial vessel, to thereby locate one of the at least one contact element right above the arterial vessel. A pressing device is provided for moving each contact element relative to the main frame, in a direction toward the surface, for forcing each contact element against the surface.
