    • Tube arrangement, including means (11, 12) for connection to a water source (15), a powder cartridge (9) or means (22'') for connection of a powder cartridge and means (7) for connection to a monitor for preparation of a medical solution, for example dialysis fluid, replacement fluid for haemofiltration or fluid for peritoneal dialysis.
      The tube set according to the invention is characterized by means (10; 10', 8a', 8b'; 10'', 10''', 8a, 8b) for lowering the water pressure to substantially atmospheric pressure.
      The invention also relates to a process for supplying a powder concentrate to a monitor (1) for preparation of a medical solution for example a dialysis solution, replacement fluid for haemofiltration or dialysis fluid for peritoneal dialysis, whereby the powder concentrate is supplied instead of a concentrate in liquid form, which the monitor is arranged to normally take from a vessel at atmospheric pressure.
      The process according to the invention is characterized in that the powder is dissolved by the through-flow of water from a water source whereby the dissolving occurs substantially at atmospheric pressure, which pressure is also maintained during the subsequent transportation to the monitors normal intake of concentrate.
    • 管装置,包括装置(11,12),用于连接到水源(15),粉末盒(9)或装置(22“”),用于(7),用于连接到监视器用于粉末盒和手段的连接 制备的医用溶液,例如透析液,置换液为用于腹膜血液过滤或透析液。 管道组gemäß的发明是由意指特征(10; 10“ 8A”,8B“ 10' ”,10' ”,8A,8B),用于降低水的压力基本上为大气压力。 因此本发明涉及一种方法,用于供给粉末浓缩物的监视器(1)在制备用于实施例的医用溶液透析溶液,用于腹膜透析滤过或透析液置换液,由此,粉末浓缩物是用提供的,而不是 浓缩液体形式,其中监视器被设置为从通常在大气压力下的容器中采取。 过程雅丁于本发明中DASS模粉末的特征在于,通过在氮气下将通流的水从水源,由此溶解在大气压力下,该压力在随后运输到监视器正常摄入浓缩物的过程中,因此基本上保持发生 ,
