Bedside Brain Monitoring System

Soterix Medical functional Near Infrared Spectroscopy (fNIRS)

The NIRSIT ON is a device designed to measure regional oxygen saturation (rS02) and hemodynamic variations (ΔHb02, ΔHbR) in the prefrontal cerebral cortex by placing two patches (left/right) radiating a near-infrared light beam, at two/four wavelengths. The setup of the NIRSIT ON system includes Main Module, Link Module, patches, and a Surface Pro Tablet. We improved measurement accuracy by utilizing its advanced algorithm that compensates for the variations in optical components.

Key features

  • Provides non-invasive regional tissue oxygen saturation (rS02) monitoring - Absolute rS02 accuracy of 4%.
  • Uses dual sources and quadruple detectors to minimize artifacts.
  • Continuous measurement of (ΔHb02, ΔHbR, and ΔHT) with 32Hz temporal resolution.
  • CSV file format support for measured data.
  • Four-wavelength LED or Laser sources.
  • Flexible disposable patches for various head sizes and personal hygiene.
  • Tolerant to the ambient light.
  • User-friendly graphical interface using tablet-based monitor.
