Abstract
An optical measurement device is presented. The device is attachable to the patient's body and adapted for performing non-invasive measurements of blood-related signals. The device comprises a measurement unit for applying optical measurements to a first region on the patient's extreme organ, and an occlusion assembly for applying over-systolic pressure to a second region on the patient's body located upstream of the first location with respect to a normal blood flow direction. A substantially flexible, heating element is provided within the measurement unit, and is accommodated so as to engage at least a part of the first region for heating it to a desired temperature.
