Abstract: Gas flow reversing element (1) for the use of a gas supply (14) under excess pressure, in particular inspiratory gases, for selectively generating a gas flow (8) from or to a line connector (6) which can in particular be connected to an airway of a patient, said gas flow reversing element (1) being designed as a main piece (2), the main piece (2) at least comprising an inflow region (9), a nozzle region (15) and a mixing region (16), and further a branching piece (3), the inflow region (9) connecting a pressure connector (4), for connection to the gas supply (14), to at least one closable outlet opening (5) arranged in the mixing region (16), and the branching piece (3) connecting the nozzle region (15) of the main piece (2) to the line connector (6), wherein a nozzle (7), particularly an injector nozzle, is configured and arranged in the nozzle region (15) in such a way that, a gas flow (8) flowing along a first flow path (20) through the main piece (2) from the pressure connector (4) subsequently through the inflow region (9), the flow region (28), the nozzle region (15) and through the nozzle (7) into the mixing region (16) to the outlet opening (5), with the outlet opening (5) opened, can generate a gas flow (8) in the branching piece (3) flowing along a second flow path (21) from the line connector (6) and subsequently through the branching piece (3), through the nozzle region (15) and through the mixing region (16) to the outlet opening (5), wherein the gas flow reversing element (1) further comprises a bypass (18) connecting the pressure connector (4) and the line connector (6) so that a gas flow (8) can flow along a third flow path (22) via the inflow region (9), the bypass (18) and the branching piece (3), wherein at least the bypass (18) and the flow region (28) are closable by at least one closing element (19), so that the gas flow (8) can bypass the nozzle (7) in the nozzle region (15) via the bypass (18) along the third flow path (22). The invention further relates to method for controlling expiration of a patient.

Abstract: A gas flow reversing element is disclosed that includes a main piece comprising an inflow region, a nozzle region and a mixing region, and further includes a branching piece. The inflow region connects a pressure connector to a closable outlet opening in the mixing region, the branching piece connecting the nozzle region to a line connector. With the outlet opening opened, gas flow flowing along a first flow path from the pressure connector through the nozzle to the outlet opening, generates a gas flow in the branching piece flowing along a second flow path from the line connector to the outlet opening. The reversing element further includes a bypass, closable by at least one closing element, connecting the pressure connector and the line connector so that a gas flow can flow along a third flow path via the inflow region, and bypass the nozzle via the bypass.
