OrSense, out of Nes Ziona, Israel, is releasing today a new pulse oximeter. Being presented at the 29th International Symposium on Intensive Care and Emergency Medicine, in Brussels, the NBM-200MP can do continuous monitoring of oxygen saturation, hemoglobin, as well as glucose levels in blood. According to the company, the system uses a ring around the finger that applies pressure to create a mild blood flow occlusion, and that in turn allows more accurate measurement of the blood content.
About the NBM-200MP pulse oximeter from OrSense:
OrSense’s NBM-200MP monitors and displays oxygen saturation of Hb (SpO2), low perfusion oximetry, SpO2 pulse rate, plethysmogram and hemoglobin, all non-invasively and continuously. The NBM-200MP permits continuous patient monitoring with adjustable alarm limits for oximetry and pulse rate, as well as visible and audible alarm signals. A ring-shaped sensor is fitted on the patient’s finger and temporarily gently squeezes the finger to over-systolic pressure, similar to blood pressure measurements. A highly sensitive optical system, using an array of calibrated light sources, measures light absorption and scattering. The desktop monitor then analyzes the blood constituents and displays the results. The NBM-200MP represents a breakthrough in non-invasive and continuous blood analyte testing, while greatly improving patient safety and comfort, eliminating infection risk, and providing the caregiver with superior accuracy and immediate results.
OrSense’s patented technology, known as Occlusion Spectroscopy, uses a non-invasive optical measurement platform combined with a finger attached ring-shaped sensor probe. The pressure applied by the sensor temporarily occludes the blood flow in the finger, creating new blood dynamics which generate a unique, strong optical signal, yielding a high signal-to-noise ratio that is wholly blood specific. Analysis of the signal provides the sensitivity necessary to measure glucose, hemoglobin, oxymetry (under severe low perfusion levels), pulse-rate, and other analyte concentrations.
This breakthrough technology enables a generation of transmission signal across the finger which overcomes the key technological barrier related to the low signal to noise ratio, due to poor or compromised peripheral perfusion , interferences from motion induced noise and other artifacts.
