Abstract
A respiratory assistance device, includes an inhalation branch (2) which is permanently connected, at its upstream end, to a first source (1) of a flow of pressurized gas and, at its downstream end, to a user's airway; at least a first (9) and a second (3) exhalation valve, these being arranged on the respiratory branch (2) and controlled so that they are closed during the inhalation phase; a detection unit (10) which, in proximity to the downstream end of the inhalation branch, detects the user's respiratory activity and sends a respiratory-activity data item to drive element (12), the drive element (12) controlling the first gas flow source (1) in such a way as to deliver a gas stream with substantially constant non-zero flow rate to the inhalation branch (2) throughout the exhalation phase.
