Multi-channel Tissue Oxygenation monitor (Hb14-n)

Features

  • Algorithm: unique space-resolved NIRS algorithm patented by Shizuoka University
  • By setting the subcutaneous tissue thickness, the measured value is equivalent to the absolute value
  • Flexible structure that also fits curved surface of human body
  • Probe weight is only 10g, made from silicone rubber
  • Wireless, Blue-tooth Ⅱ (available distance max 10m)
  • Measurement data is displayed in real time on the PC, and it is saved in CSV file format at the same time

Technical Concept

As shown in the figure on the left, the probe attached to the human body surface irradiates two near infrared rays of different wavelengths from the LED, and detects the light transmitted through the inside of the living body with the light receiving element, Measure oxygen concentration non-invasively.

To eliminate insufficient quantitativeness due to the influence of the subcutaneous fat layer as the most characteristic, spatial inclination of the living tissue was obtained by using two light receiving elements of different distances, and the precision of the relational expression was improved It is in.

Therefore, as a result of eliminating the influence of the subcutaneous fat layer as much as possible, the measurement error is within 2 to 3%, close to the absolute value as much as possible compared to the conventional method.
