3.8
concentrate generator
system where the concentrate is delivered to the user as a powder in a container, suitable for attachment to the dialysis machine with which it is intended to be used, and then converted into a liquid concentrate by the dialysis machine
Note: The solution produced by the concentrate generator is used by the dialysis machine to make the final dialysis fluid delivered to the dialyser.
3.9
concentrate mixer
mixer for preparation of dialysis concentrate or dialysis fluid at a dialysis facility
3.10
dialysis fluid delivery system
device that:
1) Prepares dialysis fluid on line from dialysis water and liquid concentrate or that stores and distributes premixed dialysis fluid;

4) Prevents dialysis during disinfection or cleaning modes
Note 1: The term includes reservoirs, conduits, proportioning devices for the dialysis fluid, and monitors and associated alarms and controls assembled as a system for the purposes listed above.
Note 2: The dialysis fluid delivery system can be an integral part of a single-patient dialysis machine or a centralized preparation system which feeds multiple bedside monitoring systems.
Note 3: Dialysis fluid delivery systems are also known as proportioning systems and dialysis fluid supply systems.
3.11
dialysis water
