An apparatus for fractionating a cell suspension, which comprises a casing having a substantially columnar space in the interior, which is substantially closed to the space outside the casing, a liquid-treating chamber in the casing adapted to be filled with a cell suspension passing through this liquid-treating chamber, a separating membrane having a separating wall surface inside the casing and disposed to separate and cause a cell component to pass through the separating membrane, a rotary body rotatably arranged in the liquid-treating chamber, a driving mechanism for rotating and driving the rotary body, a cell suspension introduction path, a treated liquid discharge path, and a separated component discharge path.

Apparatus for separating cell suspension

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.
