Apparatus for holding and positioning an arterial pulse pressure sensor
First Claim
1. A sensor holding and positioning device, comprising:
- a sensor base having at least two feet, the base forming a raised bridge between the two feet, the bridge having one or more cross members spanning all or part of the space between the two feet, wherein the two feet are positioned on either side of an area to be sensed such that the space between the feet is over the area to be sensed;
a sensor suspension including a sensor holder and sensor-height-adjustment mechanism; and
a pivot-arm axle having a long axis, the axle coupled to and between the sensor suspension and the sensor base such that the sensor suspension is able to rotate in an arc about the long axis of the axle over the area to be sensed.

Abstract
A sensor holding and positioning device. In one embodiment, the device includes a sensor base having two feet, the base forming a raised bridge between the two feet. The bridge has one or more cross members spanning all or part of the space between the two feet. A sensor suspension including a sensor holder and sensor-height-adjustment mechanism is coupled by a pivot-arm axle to the sensor base, such that the sensor suspension is able to rotate in an arc about the long axis of the axle. In one such embodiment, the device further includes a pressure sensor attached to the sensor holder of the sensor suspension. In another such embodiment, the sensor suspension is able to slide back and forth along a line parallel to the long axis of the axle. Another aspect is for positioning the sensor over the radial artery, for example in a human'"'"'s wrist. Yet another aspect is a pulse-waveform acquisition system. In one embodiment, such a system includes a wrist stabilizer, the stabilizer comprising a first member shaped on a forearm portion to conform to contours of a forearm, shaped on a wrist portion to contours of a wrist, and shaped on a hand portion to the contours of a hand, and forming an angle of approximately 150 degrees between the forearm portion and the hand portion, the stabilizer further including straps for holding the forearm and hand to the stabilizer.
