OPTICAL VITAL SIGN DETECTION METHOD AND MEASUREMENT DEVICE
First Claim
1. A vital sign measurement device comprising:
- a sensor fixation device adapted to be placed against an anatomical location of a subject, within which is an artery;
an optical sensing system comprising an optical source, an optical refractor, and an optical detector, all of which are held by the sensor fixation device and move with movement of the sensor fixation device, the optical sensing system positioned with respect to the sensor fixation device to sense movement corresponding to an arterial pulse when the sensor fixation device is placed against the anatomical location of the subject, the optical sensing system sensing an arterial pulse from the movement, bending, or compression of at least one portion of the optical sensing system relative to other portions of the optical sensing system resulting in a change in an optical signal received by the optical detector; and
an output unit that receives, from the optical sensing system, an input indicative of movement corresponding to an arterial pulse and that generates, using the input, a measure of the vital sign.

Abstract
A vital sign measurement device includes a sensor fixation device, an optical sensing system, and an output unit. The sensor fixation device is adapted to be placed against an anatomical location of a subject, within which is an artery. The optical sensing system includes an optical source, an optical refractor, and an optical detector, all of which are held by the sensor fixation device and move with movement of the sensor fixation device. The optical sensing system is positioned with respect to the sensor fixation device to sense movement corresponding to an arterial pulse when the sensor fixation device is placed against the anatomical location of the subject. The optical sensing system can sense an arterial pulse from the movement, bending, or compression of at least one portion of the optical sensing system relative to other portions of the optical sensing system resulting in a change in an optical signal received by the optical detector. The output unit receives, from the optical sensing system, an input indicative of movement corresponding to an arterial pulse and generates, using the input, a measure of the vital sign.

24. A method of measuring a vital sign of a subject, the method comprising:
-
placing a sensor fixation device against an anatomical location of a subject, within which is an artery, the sensor fixation device holding an optical sensing system comprising an optical source, an optical refractor and an optical detector, all of which are held by the sensor fixation device and move with movement of the sensor fixation device; sensing movement corresponding to an arterial pulse by operating the optical sensing system, the arterial pulse resulting in the movement, bending, or compression of at least one portion of the optical sensing system relative to other portions of the optical sensing system resulting in a change in a optical signal received by the optical detector; and generating a measure of the vital sign using an input indicative of the changes in the amount of optical energy received by the optical detector. - View Dependent Claims (25, 26, 27, 28, 29, 30)
