ABSTRACT:
An artery applanation actuator for use in a system for noninvasively determining the intra-arterial blood pressure of a user incorporates a fluid actuator to effect movement of a sensor. The movement of the sensor is effective for applanating an artery of interest and measuring the stress of the tissue overlaying the artery of interest. Alternative embodiments of the artery applanation actuator are presented wherein an electric motor is used to activate a rotating arm which has a sensor located thereon. The rotation of the arm causes the sensor to contact and press against the tissue overlying the artery of interest. The artery applanation actuator is presented having a protective sheath surrounding the sensor to protect the sensor against inadvertent contact.
