OrSense, a medical device company that develops non-invasive monitoring systems for measurements of oxygen saturation, hemoglobin, glucose and other blood parameters, has unveiled a new non-invasive hemoglobin (Hb) monitor, which enhances recruitment and retention of blood donors.
OrSense’s portable non-invasive device operates via a ring-shaped sensor that is fitted on the donor’s finger and applies pressure, temporarily occluding local blood flow.
During the occlusion, optical elements in the sensor perform a sensitive measurement of the light transmitted through the finger.
OrSense CEO Lior Ma’ayan said non-invasive Hb monitor increases donors and staff safety and allows for simple operation by the staff.
"All sides have to gain from non-invasive pre-donation Hb measurements: it increases donors’ comfort, and thus, we believe, will boost recruitment and retention of blood donors and encourage young, first time donors to donate blood," Ma’ayan said.
