Abstract: A speech valve for placing and fitting on a tracheostomy cannula, having a throughflow body enclosing a throughflow channel which on one side at one end has a connection for joining to a proximal end of the tracheostomy cannula, a one-way valve located at an end of the throughflow body opposite the connection, and, at a distance along the throughflow channel between the connection and the one-way valve, a valve opening is located which is closable by an overpressure valve. The overpressure valve arrangement has at least one elastically deformable valve flap which, in a first state covers the valve opening provided between the connection structure and the one-way valve on the throughflow body and, at a predefinable overpressure occurring inside the throughflow channel converts, by an overpressure-driven elastic deformation of the valve flap, to a second state, in which it at least partially exposes the valve opening.

Abstract: The invention relates to a respiratory device for ventilating a patient. The respiratory device comprises a respirator that is or can be linked with an endotracheal tube or a respiratory mask. The respiratory device is provided with a control/regulation unit (1) for controlling and checking the expiration phase and with actuators (2, 39) controlled by the unit for actively influencing expiration and producing any expiration pattern during the expiration phase.
