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: The invention relates to a ventilation device for ventilating a patient, comprising at least a fluid supply unit or, additionally, a fluid discharge unit which can be used to guide a fluid into at least one airway, that is part of a lung or in a lung, of a patient or for discharging the fluid from said airway; and to a control device which, during the ventilation of at least one airway of the patient, can be used to guide a fluid into the at least one airway and/or discharge the fluid from at least one airway by operating the ventilation device, for determining or also for estimating a path of at least one region of a compliance curve of the at least airway by guiding and/or discharging the fluid from the at least one airway and by determining at least one value of the compliance. The invention also relates to a method for operating a ventilation device.

Abstract: The present invention relates to an arrangement (1) comprising a switchable connection (2) and a gas flow reversing element (3), e.g. according to WO 2008/113752 A1, which is suitable for using a gas supply (4), in particular oxygen, which is at excess pressure in order to selectively generate a gas stream (5) from or to a line connection (6) which can be connected, in particular via a lumen (7), to an airway of a patient (8); wherein the switchable connection (2) is arranged at the branching piece (10) or at the line connection (6) and switchably connects at least one second line (15) to the first line (13), wherein the switchable connection (2) has at least two switching positions (16, 17), wherein (1) in the first switching position (16) the first line (13) is open and the second line (15) is closed, such that the gas flow (5) through the connection (2) can flow in both directions along the first line (13); (2) in the second switching position (17), if the switchable connection (2) is arranged at the branching piece (10), the second line (15) is fluidically connected, via the connection (2), to the line connection (6) and in particular to the lumen (7) or, if the switchable connection (2) is arranged at the line connection (6), the second line (15) is connected to the lumen (7).
