摘要: A dialyzer is formed by first placing a film strip into a membrane hose and then simultaneously folding the hose and a netting intermediate layer so that the folds of the hose and the folds of the netting extend crosswise relative to each other in a mutually interlocking manner. The facing ends of the hose layers are then sealed with a curable sealing compound and severed. Then the film strips are withdrawn from the hoses in the so formed package. The resulting product is a dialyzer or hemofilter, depending on the type of membrane hose used, in which the facing ends of the membrane hoses are open for the passage of blood therethrough, after the withdrawal of the film, and in which the netting layers are located between adjacent hoses.

摘要: Air or gas is prevented from entering into the exchange zone of an artificial organ such as an artificial kidney, dialyzer, or hemofilter. For this purpose a separating path is arranged in parallel with the artificial organ or with the exchange zone or other operative portion of the artificial organ between the liquid inflow and outflow conduits. This parallel path is provided with a high flow resistance for the liquid and with a low flow resistance for the air. Such differential flow resistance may, for example, be accomplished by apertures, gas permeable materials, and eddy chambers. The gas separating path is incorporated as an integral part of the artificial organ or as an integral part of the liquid inflow and outflow conduits. According to several embodiments, an enlargement is provided in the separating path or conduit in which the liquid may "rise and dwell" to enhance air separation before the liquid flows into the operative portion of the artificial organ.
摘要翻译: 防止空气或气体进入诸如人造肾脏,透析器或血液滤膜器的人造器官的交换区。 为此目的,分离路径与人造器官或人造器官的交换区域或其他操作部分平行布置在液体流入和流出管道之间。 该平行路径具有用于液体的高流动阻力并且具有用于空气的低流动阻力。 这种差动流动阻力可以例如通过孔,气体可渗透材料和涡流室来实现。 气体分离路径作为人造器官的整体部分或作为液体流入和流出管道的组成部分结合。 根据若干实施例,在液体流入人造器官的手术部分之前,液体可能在其中“上升和停留”的分离路径或导管中提供增大以增强空气分离。

摘要: A hollow fiber dialyser comprises a webbing of hollow fibers. A loose warphread at each end of a webbing wound on a core, acts as a wick barrier to prevent sealant from leaking into the interstices between the hollow fibers. A tight warp thread nearest the open ends of the fibers pinches off the free inner cross section of each hollow fiber to prevent sealant from penetrating into the hollow fibers.

摘要: The present mass transfer apparatus between two media is especially adapted to blood dialysis. To assure an undisturbed flow of the blood through the dialyser and to avoid coagulation all flow channels are shaped to avoid dead corners and choking zones so that the blood is prevented from forming wakes or so-called "dead waters" in its flow path. For this purpose a hollow space is formed adjacent to the open ends of the hollow fibers. The inlet and/or outlet to this hollow space may extend radially axially or tangentially.
