A novel probe holder enables precise, long-term measurement of intranasal microcirculation using laser Doppler flowmetry. This adjustable device, adaptable to various anatomies, also supports other intranasal monitoring applications.

Area of Science:

  • Biomedical Engineering
  • Physiological Measurement
  • Microcirculation Research

Background:

  • Assessing intranasal microcirculation is crucial for understanding various physiological and pathological conditions.
  • Existing methods for long-term intranasal measurements can be cumbersome or lack precision.
  • The need for a stable and adaptable platform for continuous intranasal monitoring is evident.

Purpose of the Study:

  • To describe a novel, adjustable probe holder designed for long-term intranasal microcirculation measurements.
  • To evaluate the device's capability for precise probe insertion and adaptability to diverse physiognomies.
  • To explore the potential utility of the probe holder for other intranasal measurements.

Main Methods:

  • Development of a custom probe holder based on a modified, commercially available shooting-spectacles frame.
