SYSTÈME D’IMAGERIE 3D POUR LA SURVEILLANCE DE LA RESPIRATION AUX SOINS INTENSIFS PÉDIATRIQUES

Une alternative non-invasive

-Description en anglais seulement-

Market opportunity for respiratory monitoring in intensive care

  • Vital signs must be continuously measured in pediatric intensive care unit (PICU) to ensure patient’s safety
  • Under mechanical ventilation, all parameters are directly measured with the ventilator
  • Unmet need in spontaneous breathing patients, where respiratory parameters are roughly estimated:
    • Erroneous measurement of respiratory rate (RR) that is sensitive to movement
    • No tidal volume (Vt) assessment
    • Subjective estimation of retraction signs
  • Vital signs monitoring devices global market expected to reach USD 7,3 billion by 2025
  • Neonatal intensive care respiratory devices global market expected to reach USD 2,1 billion by 2027

A non-invasive breath monitoring device

  • A new contactless breath monitoring system based on a computer vision method
  • Efficient positioning of 2 RGB-D (red green blue-depth) cameras at different view angles in the PICU room
  • Very large spatial coverage of the thoraco-abdominal (TA) zone
  • Depth information exploited to reconstruct a 3D surface of a patient’s torso

High performance at estimating respiratory parameters

  • High temporal and spatial resolution
  • Very accurate, precise and quantitative estimation of Vt, RR, minute ventilation and inspiratory time
  • The first method for the objective assessment of retraction signs and TA asynchrony (TAA)
  • System compared to the gold standard method (mechanical ventilator) at the PICU of Ste-Justine University Hospital Center

PARTNERING OPPORTUNITY

  • PCT application
  • In-licensing opportunity for technology development and commercialization
