Non-Invasive Hemoglobin Monitor by OrSense

A noninvasive hemoglobin (Hb) monitor, which measures key blood parameters, reduces the risk of a technician’s contact with donor blood.

The portable noninvasive device operates via a ring-shaped sensor that is fitted on the donor’s finger. The device applies pressure, temporarily gently squeezing the finger to over-systolic pressure, similar to blood pressure measurements, thus occluding local blood flow. During the occlusion, optical elements in the sensor, using an array of calibrated light sources, measure absorption, and scattering of the light transmitted through the finger.
