Abstract
A system for preparing a fluid intended for a medical procedure substantially at the time of use by mixing of at least one concentrate in powder form with water. The system includes a reservoir for a source of water, at least one vessel containing a concentrate in powder form and a concentrate fluid circuit for withdrawing a small quantity of water from the reservoir and passing same through the vessel containing the concentrate in powder form in order to dissolve the concentrate to produce a concentrate fluid, and for then conducting the concentrate fluid to a primary fluid circuit communicating with the reservoir so that the produced concentrate fluid is mixed with the rest of the water withdrawn from the reservoir. In a preferred embodiment, the vessel comprises a self-contained cartridge containing a quantity of concentrate in powder form therein which is suitable for one treatment procedure. The system is intended in particular for the preparation of fluids for use in connection with medical procedures such as hemodialysis, hemodiafiltration and hemofiltration. However, it may also be used for the preparation of fluids for other medical procedures or treatments as well.
