    摘要: A coupling between a breathing tube system is provided with an inner tube and an outer tube. A first connection part is provided with a first connection piece for the outer tube and with a first connection for the inner tube. The first connection is arranged eccentrically in the first connection piece. A second connection part is provided with a second connection piece, which is in flow connection with the first connection piece. The second connection part provides a second connection, which is arranged concentrically in the second connection piece and which is connected to the first connection in terms of flow.

    摘要: The invention is directed to an expiration valve control arrangement for a ventilating apparatus. The control arrangement includes a control valve for generating a control pressure in the control chamber of an expiration valve. The control valve includes a connecting passage supplied from a control gas source via a control gas line. The connecting passage opens into an outflow chamber of the control valve and the outflow chamber has an outlet to the ambient. The control valve is configured so that the dynamic end expiratory overpressure can be compensated. For this purpose, the connection passage of the control valve includes a throttle generating an underpressure and a pressure line extends from this throttle and opens into the control chamber of the expiration valve. A closure force is applied to a closure element at the outlet of the connection passage. The closure element coacts with the throttle with the underpressure being adjusted by adjusting the closure force on the closure element. The valve chamber of the expiration valve is connected to a device generating an underpressure.
