Abstract

A process for prepg. and distributing dialysis liq. to several terminals, feeding artificial kidneys, charges pre-determined amts. of concentrate and softened water to two containers, and transfers the matl. to a storage vessel through a homogenising vessel. Photoelectric cells operate valves to control the amts. of concentrate and softened water. REsistivity meters detect concn. changes and operate valves directing the flow to the storage vessel or to drain according to whether the concn. is correct or not. A nitrogen supply and an acceleration pump creating a depression i the storage vessel ensure that dissolved oxygen diffuses out of the dialysis liq. and a degassing vessel ensures liberation of nitrogen. The invention provides more reliable and safer means of ensuring correct concn. than existing appts. Breaks in distribution are avoided. Correct flow according to the number of terminals in use is assured. The dialysis liq. is free from dissolved gases which could affect the efficiency of the dialyser and which could get into the blood stream.
