摘要

Summary the nasal cannula structured to be located on a nasal cushion for a patient interface device and interface device of a patient with a nasal cannula is structured to be located on a nasal cushion of an interface device of a patient who is in sist. The fluid action with a respiratory gas source to provide a flow of gas to an airway of a patient.The nasal cannula includes a flexible sealing device structured to be deformable between a free state and a deformed state among a plurality of the deformed. At least a portion of the sealing device that is received in a nostril of the patient moves to the free state and is in compressive and vedativa the nostril in a second state deformed.A flow channel extends through the device, sealing the flow channel being structured to be in fluid communication with the source of respiratory gas and to provide the flow of respiratory gas to the nostril. 1 / 1
