ABSTRACT:
Method and apparatus for preparing a mixed fluid of accurately portioned components for hemodialysis comprises the use of a closed receptacle of fixed volume. Two or more components for the fluid are introduced into a chamber in the closed receptacle to fill it and the resultant fluid of the portioned and mixed components is delivered from the chamber. One or more of the components is introduced into the chamber in predetermined amounts, the sum of which is insufficient to fill the whole volume of the chamber, before or during which the other component is introduced into the chamber and the other component is introduced into the chamber in an amount sufficient to fill the remaining volume of the chamber. The method and apparatus are suitable for preparing dialysate solutions for the use in hemodialysis.
