OrSense presents NBM 200 non-invasive Hb measurement system at XXXIst International Congress of ISBT

OrSense Ltd., developer of monitors for non-invasive measurements of various blood parameters, announced today at the XXXIst International Congress of the International Society of Blood Transfusion (ISBT), in Berlin, Germany, the presentation of NBM 200, a non-invasive hemoglobin (Hb) measurement system for various hematological applications including anemia monitoring, hemorrhage detection and pre-donation screening. The Company presented results showing that Hb measurements obtained by the NBM 200 showed accurate performance compared with invasive point of care (POC) devices.

“Hb measurements obtained by the NBM 200 in multiple applications, showed accurate performance compared with the gold standard invasive reference values. Our non-invasive system was found to be environmentally friendly, safe, fast and easy to use by the operating staff”

Hemoglobin (Hb) measurements allow the detection of anemia and hemorrhage, and are widely used by hospital wards such as operation rooms, ICU, ER and delivery rooms. In blood donation centers, a predonation Hb measurement of blood donors is required by most countries to protect anemic donors, and to ensure adequate Hb content of blood units. The determination of Hb levels of prospective blood donors is usually performed using capillary blood obtained by finger pricking, rendering current Hb screening methods invasive, painful, time consuming and labor intensive.

Dr. Paul Holland, Former President of the ISBT, said, "OrSense's non-invasive solution has the potential for improving anemia screening and monitoring by eliminating pain, reducing infection risk and enabling a simple and fast diagnosis."

"Hb measurements obtained by the NBM 200 in multiple applications, showed accurate performance compared with the gold standard invasive reference values. Our non-invasive system was found to be environmentally friendly, safe, fast and easy to use by the operating staff," said Lior D. Ma'ayan, OrSense's CEO. "Our spot and continuous non-invasive devices, which we launched last year, are already in use for various hematological applications, improving donor and patient safety and care."

Non Invasive Hemoglobin Measurement

OrSense's non-invasive Hb measurement has many advantages including the prevention of pain and potential transmission of infectious diseases, a reduced need for trained personnel, short measurement time, and the absence of bio-hazardous waste. NBM 200 offers a unique, breakthrough, non-invasive solution for accurate and quick Hb measurements. This portable 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. This method, called Occlusion Spectroscopy, provides a quick, accurate and painless measurement of the donor's blood constituents, while greatly improving the donor's comfort, eliminating infection risk, and providing the medical staff with accurate readings and immediate results.
