Classification: A61B

Abstract:
An optical measurement device for attaching to a patient's body to perform non-invasive measurement of blood-related signals, the device comprising:a measurement unit adapted to be attached to one of the patient's extreme organs, the measurement unit being made up of an illumination-detection assembly for illuminating a first region within the extreme organ, detecting light response of the illuminated region, and generating data representative thereof, the measurement unit further including a substantially flexible heating element engaging at least part of the first region within the extreme organ for heating it to a desired temperature; an occlusion assembly for applying over-systolic pressure to a second region on the patient's body located upstream of the first region with respect to a normal blood flow direction; and a control unit, which is coupled to the measurement unit for selectively actuating the measurements, analyzing data indicative of the detected light response and determining at least one desired parameter of the patient's blood, said control unit being further coupled to the occlusion assembly for selectively operating said occlusion assembly.
