    • The present invention generally relates to a process suitable for extracorporeal lung support. The process comprises contacting blood with a dialysis liquid separated by a semipermeable membrane. Oxygen is introduced into blood and/or into the dialysis liquid prior to contacting blood and dialysis liquid being separated by the semipermeable membrane. The process is versatile and allows for blood oxygenation as well as removal of at least one undesired substance occurring in the blood, selected from carbon dioxide, bicarbonate and hydrogen cations, from blood. Thereby, the present invention takes advantage of the Haldane effect in the extracorporeal contacting step. The undesired substance can be efficiently transported across a semipermeable membrane to the dialysis liquid. In contrast to extracorporeal carbon dioxide removal methods of the prior art (ECCCbR), the present invention employs a versatile dialysis liquid that allows to adjust the pH and buffering capacity of the dialysis liquid, to add fluids to the dialysis liquid and/or to the blood and to remove substances from the blood in the extracorporeal circuit, depending on the conditions and needs. The present invention also provides regeneration and recycling of the dialysis liquid, and thus for its repeated use. The present invention is suitable for treating human or animal subjects suffering from lung failure or lung disorders.
    • 本发明总体上涉及适用于体外肺部支持的方法。 该方法包括使血液与通过半透膜分离的透析液接触。 在血液和透析液被半透膜分离之前,将氧气引入血液和/或透析液中。 该过程是通用的并且允许血液氧合以及从血液中去除血液中存在的至少一种不需要的物质,所述物质选自二氧化碳,碳酸氢盐和氢阳离子。 由此,本发明利用了体外接触步骤中的霍尔丹效应。 不需要的物质可以有效地通过半透膜传送到透析液。 与现有技术的体外二氧化碳去除方法(ECCCbR)相比,本发明采用多功能透析液,其允许调节透析液的pH和缓冲能力,将液体添加到透析液和/或透析液 根据条件和需要,从体外回路中的血液中去除物质。 本发明还提供了透析液的再生和再循环,并因此用于其重复使用。 本发明适用于治疗患有肺衰竭或肺病的人或动物受试者。
