Abstract

L’invention concerne un appareil (1, 101, 101’, 201) de production de flux pour ventilation non invasive ou oxygénothérapie à haut débit comprenant : au moins un dispositif venturi (2, 204) destiné à fournir un mélange de gaz ; au moins une entrée d’air (3) dans ledit dispositif venturi, comprenant au moins un élément d’étranglement (3A) destiné à doser la quantité d’air aspirée dans ledit dispositif venturi (2, 204) ; un élément d’interface (12) qui couvre complètement ou partiellement les voies respiratoires du patient et comprenant un orifice d’entrée du mélange des gaz frais (11) ; un premier conduit (10) destiné à établir une liaison fonctionnelle entre le dispositif venturi (2, 204) et l’élément d’interface (12) ; au moins un premier débitmètre (5, 105, 203), associé au dispositif venturi (2, 204) par l’intermédiaire d’au moins un raccord d’alimentation (4) et destiné à doser le mélange de gaz. Figure pour l’abrégé : Figure 1The invention relates to an apparatus (1, 101, 101', 201) for producing flow for non-invasive ventilation or high flow oxygen therapy comprising: at least one venturi device (2, 204) for supplying a mixture of gases; at least one air inlet (3) into said venturi device, comprising at least one throttle element (3A) for metering the amount of air sucked into said venturi device (2, 204); an interface member (12) which completely or partially covers the patient's airway and includes a fresh gas mixture inlet (11); a first conduit (10) intended to establish a functional connection between the venturi device (2, 204) and the interface element (12); at least a first flow meter (5, 105, 203), associated with the venturi device (2, 204) via at least one supply connection (4) and intended to meter the gas mixture.
