nasal adapter system for cpap ventilator

摘要

A nose adapter (2) and system, for use in noninvasive respiratory support, has a proximal end, for coupling to the nose, and a distal end for coupling to a ventilation device. An inspiratory channel (6) and an expiratory channel (7) extend between the proximal and distal end. The distal ends of the channels terminate in a respective connection adapter (30, 31) for connecting ventilation tubes (4). The proximal ends of the inspiratory and the expiratory channels are bent inwards 90° such that the openings of the channels face each other. A cylindrical tube element (34), rotatably held between the openings, has a through-opening in the cylindrical circumferential surface of the tube element. A connection nozzle (13) connects to a prong or a nose mask and is formed on the outer face of the rotatable tube element (34), in alignment with the through-opening, such that the connection nozzle can pivot.
