Vital Sign Detection Method and Measurement Device
First Claim
1. A vital sign measurement device comprising:
- an occluding device adapted to be placed against an anatomical location of a subject, within which is an artery, and to apply a pressure to the anatomical location of the subject to occlude the artery;
a motion sensor positioned with respect to the occluding device to sense movement corresponding to an arterial pulse when the occluding device occludes the anatomical location of the subject, the motion sensor including a sensor pad positioned for placement against an anatomical location of a subject and to move in response to an arterial pulse; and
an output unit that receives, from the motion sensor, an input indicative of the amount of movement of the sensor pad and that generates, using the input, a measure of the vital sign.

Abstract
A vital sign measurement device includes an occluding device, a motion sensor, and an output unit. The occluding device is adapted to be placed against an anatomical location of a subject, within which is an artery, and to apply a pressure to the anatomical location of the subject to occlude the artery. The motion sensor is positioned with respect to the occluding device to sense movement corresponding to an arterial pulse when the occluding device occludes the anatomical location of the subject. The motion sensor includes a sensor pad positioned for placement against an anatomical location of a subject and to move in response to an arterial pulse. The output unit receives, from the motion sensor, an input indicative of the amount of movement of the sensor pad and generates, using the input, a measure of the vital sign.

21. A method of measuring a vital sign of a subject, the method comprising:
-
placing an occluding device against an anatomical location of a subject, within which is an artery, and applying a pressure to the anatomical location of the subject with the occluding device to occlude the artery, the occluding device holding a motion sensor having a sensor pad;
reducing the pressure applied to the anatomical location of the subject;
sensing movement of the sensor pad corresponding to at least one arterial pulse; and
generating a measure of the vital sign using an input indicative of the amount of sensed movement of the sensor pad. - View Dependent Claims (22)
