    摘要： The present invention relates to a device and a method for blood treatment in a single-needle operating mode. The blood treatment device has an extracorporeal blood circuit comprising a blood supply line leading to the inlet of a blood treatment unit and a blood return line leading away from the outlet of the blood treatment unit. Blood collecting means, for example a blood collecting container, is provided in the blood return line, said means being connected to means for storing gas, for example an air reservoir, by a flow line. The flow connection comprises two line branches, one branch being used to transfer gas from the air reservoir into the blood collecting container and the other branch being used to transfer gas from the blood collecting container into the air reservoir. The connection branch for transferring gas from the air store into the blood collecting container contains means for compressing air, for example a compressor. The device according to the present invention may be operated in such a way that the filling level of the means for collecting blood can be determined as precisely as possible.

    摘要翻译： 本发明涉及在单针操作模式下进行血液处理的装置和方法。 血液处理装置具有体外血液回路，其包括通向血液处理单元的入口的血液供给管线和远离血液处理单元的出口的血液回流管路。 血液收集装置例如采血容器设置在血液返回管线中，所述装置通过流动管路连接到用于储存气体的装置，例如储气器。 流动连接包括两个分支，一个分支用于将气体从空气储存器传送到采集容器中，另一个分支用于将气体从采集容器转移到储气器中。 用于将气体从空气存储器传送到采集容器中的连接支路含有用于压缩空气的装置，例如压缩机。 根据本发明的装置可以以可以精确地确定用于采集血液的装置的填充水平的方式操作。
