Title
(EN) PATIENT INTERFACE FOR DELIVERY OF GAS
(FR) INTERFACE PATIENT POUR L'ADMINISTRATION DE GAZ
Abstract
(EN) A patient interface for delivery of gas to a patient comprises at least one inspiratory element for directing a flow of gas to a patient airway, at least one expiratory element comprising an expiratory gas flow path for directing expiratory gases from the patient; and at least one gas permeable body in the expiratory gas flow path. Each inspiratory element comprises at least one inspiratory lumen through which said flow of gas is directed. The gas permeable body is configured such that expiratory gases in the expiratory gas flow path are directed through the gas permeable body before exiting the patient interface.
(FR) La présente invention concerne une interface patient pour l'administration de gaz à un patient qui comprend au moins un élément d'inspiration pour diriger un flux de gaz vers les voies aériennes d'un patient, au moins un élément d'expiration comprenant un trajet d'écoulement de gaz d'expiration pour diriger des gaz d'expiration provenant du patient ; et au moins un corps perméable aux gaz dans le trajet d'écoulement de gaz d'expiration. Chaque élément d'inspiration comprend au moins une lumière d'inspiration par laquelle ledit écoulement de gaz est dirigé. Le corps perméable aux gaz est conçu de telle sorte que les gaz d'inspiration dans le trajet d'écoulement de gaz d'inspiration sont dirigés à travers le corps perméable aux gaz avant de sortir de l'interface patient.
