    • 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.
    • 用于在过压下使用气体供应(14)的气体流动反向元件(1),特别是吸气气体,用于选择性地从线连接器(6)产生气流(8),线路连接器(6)可特别连接 所述气体流动反向元件(1)被设计为主要部件(2),所述主体部件(2)至少包括流入区域(9),喷嘴区域(15)和混合物 区域(16)以及另外的分支件(3),将用于连接到气体供应装置(14)的压力连接器(4))的流入区域(9)连接至至少一个可关闭的出口开口(5) 混合区域(16)和将主片(2)的喷嘴区域(15)连接到线路连接器(6)的分支片(3),其中喷嘴(7),特别是喷射器喷嘴 并且以这样的方式布置在喷嘴区域(15)中,使得沿着第一流路(20)从压力连接器(4)流过主件(2)的气流(8) 随后通过流入区域(9),流动区域(28),喷嘴区域(15)和通过喷嘴(7)进入到出口(5)的混合区域(16),出口开口 )打开,可以在分支片(3)中产生气流(8),该分支片(3)沿着第二流动路径(21)从线连接器(6)流动并随后通过分支片(3),通过喷嘴区域(15) )并且通过混合区域(16)到出口开口(5),其中气体流动反向元件(1)还包括连接压力连接器(4)和线路连接器(6)的旁路(18),使得 气流(8)可以经由流入区域(9),旁路(18)和分支块(3)沿着第三流动路径(22)流动,其中至少旁路(18)和流动区域(28) )可由至少一个关闭元件(19)关闭,使得气流(8)可以沿着第三流动路径(22)经由旁路(18)绕过喷嘴区域(15)中的喷嘴(7)。 本发明还涉及一种用于控制患者的呼气的方法。
