Bioprocess vessels with integrated pump
A bioprocess vessel includes a flexible bag or substantially rigid container that defines an interior volume and having a bottom surface, the bottom surface being open or containing an aperture therein for the passage of fluid. A pump is secured to the bottom surface of the flexible bag or substantially rigid container. In some embodiments is secured directly to the flexible bag or substantially rigid container. In other embodiments, the pump is secured indirectly the flexible bag or substantially rigid container using, for example, a port that extends through the aperture on the bottom surface. The port or flanged surface may also be integrated into the pump, which is secured to the vessel. An optional mixing adaptor may be provided inside the interior volume of the flexible bag or substantially rigid container and at least partially covers the inlet that leads to the pump.
1. A bioprocess vessel having an integrated pump comprising:
a flexible bag defining an interior volume and having a bottom surface, the bottom surface containing an aperture therein for the passage of fluid; and
a pump comprising a pump head and having an inlet and an outlet, the pump head being to integrally formed with or bonded to the bottom surface of the flexible bag whereby fluid passes from the interior volume of the flexible bag and into the inlet of the pump, the pump head comprising a plurality of diaphragms, each diaphragm having an associated check-valve.
2. The bioprocess vessel having an integrated pump of claim 1 , further comprising a mixing adapter secured to the pump head and disposed at least partially in the interior volume of the flexible bag, the mixing adapter having a top curved surface and at least partially covering the inlet of the pump head.
3. The bioprocess vessel having an integrated pump of claim 1 , further comprising a mixing adapter secured to the pump head via a plurality of fasteners extending through the bottom surface of the bag, the mixing adapter having a top curved surface and disposed in the interior volume of the flexible bag and at least partially covering the inlet of the pump head.
4. The bioprocess vessel having an integrated pump of claim 1 , further comprising a detachable motor secured to the pump head and driving a nutating disk or wobble plate to sequentially actuate the plurality of diaphragms.
5. The bioprocess vessel having an integrated pump of claim 1 , wherein the pump comprises a diaphragm pump or a centrifugal pump.
6. The bioprocess vessel of claim 1 , wherein the pump head is bonded to the bottom surface of the flexible bag by a weld.
7. The bioprocess vessel of claim 1 , wherein the pump head comprises a flanged end that is integrally formed with or bonded to the bottom surface of the flexible bag.
8. A single-use bioprocess vessel having an integrated pump comprising:
a substantially rigid container formed from a resin or polymer material defining an interior volume and having a bottom surface; and
a pump comprising a pump head and having an inlet and an outlet, the pump head being to integrally formed with or bonded to the bottom surface of the substantially rigid container whereby fluid passes from the interior volume of the substantially rigid container and into the inlet of the pump, the pump head comprising a plurality of diaphragms, each diaphragm having an associated check-valve.
9. The single-use bioprocess vessel having an integrated pump of claim 8 , further comprising a mixing adapter secured to the pump head and disposed in the interior volume of the substantially rigid container, the mixing adapter having a top curved surface and at least partially covering an inlet to the pump.
10. The single-use bioprocess vessel having an integrated pump of claim 8 , further comprising a lid having one or more ports formed therein.
11. The single-use bioprocess vessel having an integrated pump of claim 10 , further comprising a rotating shaft extending through the lid and into the interior of the substantially rigid container and having an impeller thereon.
12. The single-use bioprocess vessel having an integrated pump of claim 8 , further comprising a detachable motor secured to the pump head and driving a nutating disk or wobble plate to sequentially actuate the plurality of diaphragms.
13. The single-use bioprocess vessel of claim 8 , wherein the pump head is made from the same material as the substantially rigid container.
14. The single-use bioprocess vessel of claim 8 , wherein the pump head is bonded to the bottom surface of the substantially rigid container by a weld.
