MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202531092302 A) filed by Narula Institute Of Technology, Kolkata, West Bengal, on Sept. 25, 2025, for 'adaptive nonlinear control model for ventilation tuning in respiratory support devices.'
Inventor(s) include Dr. Moupali Roy; and Swati Barui.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to an adaptive nonlinear control model designed for precise ventilation tuning in respiratory support devices, such as mechanical ventilators, CPAP, and non-invasive ventilators. Traditional devices typically operate on static or linear control algorithms that fail to account for the nonlinear, dynamic, and patient-specific characteristics of respiratory mechanics. This invention introduces a control architecture based on nonlinear system identification-such as NARX, Hammerstein-Wiener, or neural-network-based models-combined with adaptive feedback loops and real-time sensor integration.The system continuously monitors pressure, volume, and flow signals from the patient and adapts the ventilation parameters (e.g., tidal volume, pressure limit, inspiratory time) in real-time using a nonlinear controller, such as model predictive control (MPC), sliding mode control, or adaptive fuzzy logic. The invention also allows the integration of machine learning algorithms for personalized tuning based on patient condition, age, or disease pattern (e.g., COPD, ARDS, asthma)."
