至少部分排空体外血液循环的方法以及用于应用此方法的血液透析仪
摘要：
本发明涉及一种用于至少部分排空体外血液循环的方法和血液透析仪，借助该方法和血液透析仪，存在于体外血液循环中的病人血液借助于排挤血液的输液返回给病人体中，并使该病人与体外血液循环分离。本发明拟至少排空通过半透膜(2)分成血液腔(3)和透析液腔(4)的血液透析仪(1)的血液腔(3)，同时无需额外将体外血液循环的动脉血液导管(5)和静脉血液导管(7)相互连接。为此使第一部位(50)的动脉血液导管(5)和/或第二部位(40)的静脉血液导管(7)主动或被动通气(belüften)，并将液体经半透膜(2)排空到透析液腔(4)和离开透析液腔的透析液排出导管(21)中。本发明方法可通过血液透析仪的控制单元(30)中的自持式运行的控制程序进行，程序触发无需由操作人员执行特别的操作步骤。
摘要（英）：

The invention relates to a method and to a haemodialysis device used to at least partially drain a extracorporeal blood flow, to which the blood of a patient, in the extracorporeal blood flow, is transferred back to the patient with the aid of an infusion fluid penetrating the blood and the patient is separated from the extracorporeal blood flow. The aim of the invention is to drain at least the blood chamber (3) of a haemodialysis device which is subdivided into a semipermeable membrane ( 2) in the blood chamber (3) and a dialysis fluid chamber, without having to also join the arterial and venous (7) blood line of the extracorporeal blood flow. The arterial blood line (5) is actively or passively aerated on a first point (50) and/or the venous blood line is actively or passively aerated on a second point (40) and the fluid in drained by means of the semi-permeable membrane (2) in the dialysis fluid chamber (4) and a dialysis fluid removal line (21) emerging therefrom. The inventive method can run by means of an automatically running control program in the control unit (30) of a haemodialysis device without requiring special operational steps to be carried out by the operating personnel after the program has been activated.
