    • An apparatus for blood treatment has a housing having a blood inlet for introducing the blood to be treated and a blood outlet for exhausting the treated blood, at least one blood channel within the housing and extending from the inlet to the outlet and being constituted by a plasma-separating membrane capable of allowing the plasma component of blood to permeate therethrough while preventing the blood cells from penetrating therethrough. A blood treating material is packed in the space within the housing around the blood channel. A pump is connected to the inlet for pumping blood into the inlet. A pressure varying mechanism operatively associated with the housing imposes from outside the housing on the space within the housing pressure changes for alternately changing the direction of the pressure difference between the inside of the blood channel and the blood treating material-containing space, so that the plasma component of the blood flow in the blood channel is caused to permeate through the plasma-separating membrane toward the blood treating material to bring the plasma into contact with the blood treating material, and the plasma is thereafter caused to be returned to the blood channel through the plasma-separating membrane.
    • 用于血液处理的装置具有壳体,其具有用于引入待处理血液的血液入口和用于排出经处理的血液的血液出口,壳体内的至少一个血液通道,并且从入口延伸到出口,并由 能够使血液的血浆成分透过的血浆分离膜,同时防止血细胞穿透。 血液处理材料被包装在围绕血液通道的壳体内的空间中。 泵连接到入口以将血液泵入入口。 与壳体可操作地相关联的压力变化机构从壳体外部施加在壳体内的空间中的压力变化,以交替地改变血液通道内部和含血液处理材料的空间之间的压力差的方向,使得 导致血液通道中的血流的血浆成分通过血浆分离膜向血液处理材料渗透,使血浆与血液处理材料接触,然后使血浆返回到血液通道 通过等离子体分离膜。

    • A hemodialysis system for use with any type of dialyzer, such as coil-type, Kiil-type and capillary-type or hollow fiber-type dialyzers, which has a fluid circulation circuit and a bypass circuit short-circuiting the fluid circulation circuit. At one junction between the fluid circulation circuit and the bypass circuit, an ejector is employed. The ejector has a nozzle, a diffuser axially aligned with the nozzle and defining an orifice and a suction chamber communicated with the orifice. During circulation of the dialysate in the circulation circuit and from the nozzle onto the diffuser of the ejector, a negative gauge pressure is developed in the suction chamber so that the dialysate can be drawn through the bypass circuit. The circulation circuit and the bypass circuit have respective coupling assemblies for removable connection with the coil-type dialyzer and with the Kiil-type or capillary-type, or hollow fiber-type, dialyzer.
    • 一种用于任何类型的透析器的血液透析系统,例如线圈型,Kiil型和毛细管型或中空纤维型透析器,其具有使流体循环回路短路的流体循环回路和旁路回路。 在流体循环回路和旁路回路之间的一个连接处,采用喷射器。 喷射器具有喷嘴,与喷嘴轴向对准的扩散器,并且限定出孔口和与孔口连通的吸入室。 在将透析液循环到循环回路中并从喷嘴循环到喷射器的扩散器上时,在吸入室中产生负表压,使得透析液可以通过旁路回路被抽吸。 循环回路和旁路回路具有用于与线圈式透析器和Kiil型或毛细管型或中空纤维型透析器可拆卸连接的各自的联接组件。
