1. A nasal adapter system for use in non-invasive respiratory support, the system comprising:

  • a nasal adapter, which has a proximal end and a distal end, wherein the proximal end is designed for coupling to the nose of a patient to be respirated, and the distal end is designed for coupling with a respirator, the nasal adapter comprising;

    an inspiratory channel;

    an expiratory channel, the inspiratory channel and the expiratory channel extending between the proximal end and the distal end of the nasal adapter, the inspiratory channel and the expiratory channel each extending in parallel, and extend adjacent, to each other, the inspiratory channel and the expiratory channel being attached to each other through a common partition which separates breathing gas in the inspiratory channel and the expiratory channel from one another;

    a tube element held rotatably between the proximal ends of the channels, the tube element being provided with a through opening in an outer circumferential surface of the tube element; and

    a connection nozzle, which is formed on an outer side of the tube element in alignment with the through opening, wherein the connection nozzle is designed for coupling with the nose of the patient to be respirated.
