Apparatus for separating cell suspension

An apparatus for fractionating a cell suspension which comprises:

• (a) a casing defining an interior space which is substantially closed to the space outside said casing, said interior space comprising a separating chamber disposed of in said casing and adapted to contain a cell suspension and including a separated component chamber,
• (b) a separating membrane having a separating surface which is interposed in said casing between the separating chamber and the separated component chamber to separate a predetermined component from said cell suspension and to cause said component to pass therethrough,
• (c) a rotary body rotatably disposed in said casing having a shearing surface confronting the separating surface of said separating membrane,
• (d) drive means connected to rotate and drive said rotary body,
• (e) means forming a liquid introduction path connected to said separating chamber,
• (f) means forming a treated liquid discharge path connected to said separating chamber, and
• (g) means forming a separated component liquid discharge path connected to the separated component chamber to deliver the separated component.

An apparatus for fractionating a cell suspension which comprises:

• (a) a casing having a substantially columnar space in the interior thereof defining an interior space which is substantially closed to the space outside said casing, said interior space comprising a separating chamber disposed in said casing and adapted to contain a cell suspension,
• (b) means in said space having a shearing surface,
• (c) a rotary body rotatably disposed in said casing having a separating membrane in said space having a separating surface which confronts said shearing surface, said membrane being disposed to separate a predetermined component from said cell suspension and to cause said component to pass therethrough, and having a separated component chamber in said space adjacent said separating membrane,
• (d) a driving mechanism engaged to rotate and drive said rotary body,
• (e) means forming a liquid introduction path connected to said separating chamber for introduction of liquid to be treated,
• (f) a trated liquid discharge path connected to said separating chamber for delivery of treated liquid, and
• (g) means forming a separated component liquid path connected to said component chamber for delivery of said separated component.
