NBM-200 Clinical Study in Blood Donation Setting

The NBM-200 is a portable Hemoglobin and oximetry monitor, based on occlusion spectroscopy technology, for non-invasive spot checking of hemoglobin (Hb), estimated Hematocrit (Hct), SpO2 and pulse rate. The NBM-200 includes a reusable ring-shaped sensor probe that fits on the patient's finger, and a portable desktop monitor that calculates and displays the measurement result. The sensor probe consists of a multi-wavelength optical measuring system and inflatable cuff employing pneumatic tissue manipulation. Blood flow in the finger can be briefly occluded and the resulting changes in its optical behavior are analyzed to provide accurate measurements of Hb.
