Device for regulating oxygen for automated oxygen therapy

A double closed-loop regulated device for regulating a flow of oxygen for automated oxygen therapy, the device comprising an oxygen flow path for passing a flow of oxygen from a source of oxygen via the device for providing a controlled flow of oxygen, the device comprising an adjustable valve and a flowmeter arranged consecutively on the oxygen flow path, and a controller configured for controlling a provided flow of oxygen through the adjustable valve by adjusting the adjustable valve in response to feedback from the flowmeter and a sensor for measuring physiological data comprising patient SpO2 and pulse rate, the sensor configured for being operatively connected to the controller;

• the controller further configured for executing a control algorithm in response to a change in measured physiological data received from the sensor indicating a patient activity involving physical exertion;
• the control algorithm arranged for permitting an iterative adaptation of the flow of oxygen through the adjustable valve by using a predictive oxygen consumption model for compensating for an increased patient oxygen consumption during physical exertion.
