    • This invention relates to a dialysis pump and pumping system primarily designed for the pumping of blood for purification in an ''''artificial kidney machine'''' using the recently announced system of the use of a single needle temporarily inserted into a vein or artery of a patient through which blood is withdrawn from the vein for purification and returned to the patient through the same needle. Such a dialysis system requires a device, commonly called an ''''occluder,'''' by means of which blood from the filter is prevented from entering the needle during the suction stroke of the pump of the machine and is open to flow during the pumping stroke which, in the preferred form, exerts a greater pressure than that supplied by the body during the suction stroke of the pump.
    • 本发明涉及一种主要设计用于在“人造肾脏机器”中泵送血液进行净化的透析泵和泵送系统,其使用最近公布的临时插入患者静脉或动脉的单针的系统,通过该系统 血液从静脉中取出以进行净化,并通过相同的针返回给患者。 这种透析系统需要通常称为“封堵器”的装置,通过该装置可以防止来自过滤器的血液在机器的泵的吸入冲程期间进入针头,并且在泵送冲程期间打开以流动, 在泵的吸入冲程期间,以优选形式施加比由身体提供的压力更大的压力。

    • The invention relates to a device (61) for controlling a system (20) for transporting blood, and a method for transporting blood in a blood line of an extracorporeal blood circuit of an extracorporeal blood treatment system. The invention also relates to an extracorporeal blood treatment device comprising such a system for transporting blood. The method and device according to the invention are based on the fact that a defined threshold value for the pressure in the blood line (9) should not be exceeded. The system (20) for transporting blood is controlled in such a way the blood in the blood line is transported in a pre-determined volume flow as long as the pressure in the blood line (9) is below the pre-determined threshold value. When the pressure in the blood line reaches the pre-defined threshold value, however, the system for transporting blood is controlled such that a pressure value corresponding to the threshold value is set when the blood is transported in the blood line. As a result, when the threshold value for the pressure is reached, a regulation of the volume flow is replaced by a regulation of the pressure in the blood line.
    • 本发明涉及一种用于控制用于输送血液的装置(20)和用于在体外血液处理装置的体外血液回路的血液管线输送血液的方法的装置(61)。 此外,本发明涉及具有用于输送血液的装置的体外血液处理设备。 该方法和根据基于这样的事实被指定为在血液管线(9)中的压力一定的极限值,这不应超过本发明的装置。 使血液以预定流率,只要输送到血液管线如在血液导管(9)低于预定极限值的压力用于输送血液的装置(20)被驱动,。 然而,如果在血液线路中的压力达到预定的极限值,用于输送血液的装置进行控制,使得在输送血液线路血液时,对应于限制值的压力被建立。 因此,达到用于气流的控制压力的限制值时被传递到血液中的管线中的压力的​​控制。
