Method for centrally preparing a salt concentrate and method for disinfecting an arrangement intended for central preparation of a salt concentrate

摘要

Arrangement and method for centrally preparing and distributing substantially saturated concentrate solution of common salt in water for preparation of a medical solution starting from a concentrate solution, for example dialysis solution and/or replacement solution for haemodialysis, haemofiltration or haemodiafiltration, as well as a method for disinfecting the arrangement, and a container intended for the arrangement. The arrangement consists of a concentrate generator (1) equipped with an inlet (4) for purified water and a distribution conduit (6) for distribution of the concentrate to concentrate connectors (8) and further to a dialysis machine (9). Several containers (2, 3) for common salt in particle form are connected to the concentrate generator via a conduit (10) for supply of water to the container and a conduit (11) for feeding the concentrate to the distribution conduit (6). By partial dissolution of the common salt in the water in the container, a substantially saturated concentrate solution is continuously formed. The container contains common salt in a quantity of, for example, 65 kg.
