Environmental containment systems
First Claim
1. An apparatus comprising:
- a vessel or a processing device having an interior comprising a container adapted for containing a liquid;
an environmental containment enclosure having an inner surface and configured for surrounding at least a portion of the vessel or the processing device, the environmental containment enclosure being configured so that at least a portion of the environmental containment enclosure has a shape and/or contour that is complementary to a shape and/or contour of an outer surface of the vessel or an outer surface of the processing device to which the at least a portion of the environmental containment enclosure is adjacent;
the inner surface of the environmental containment enclosure and the outer surface of the vessel or the processing device defining an enclosed space therebetween, at least a portion of said enclosed space not in continuous fluid communication with an interior portion of the container, and wherein said enclosed space is maintained during use of the vessel or the processing device at a pressure chosen from greater than atmospheric pressure, less than atmospheric pressure, and equal to atmospheric pressure;
an environmental treatment system in communication with the enclosed space, the environmental treatment system comprising a ventilation system in fluid communication with the enclosed space, the ventilation system comprising an inlet port dimensioned for connection to a source of gas unit for introducing gas into the apparatus and an outlet port for connection to an exhaust unit for removing a gas from the apparatus; and
a damper control configured for connection to at least one of the source of gas unit and the exhaust unit, the damper control capable of regulating pressurization within the apparatus; and
wherein the environmental treatment system and environmental containment enclosure are configured to maintain an aseptic and/or substantially particle-free environment within the enclosed space.

Abstract
Environmental containment systems, and in certain embodiments, systems and methods involving vessels and unit operations or components of cell culture, cell containment, bioreactor, chemical manufacturing, or pharmaceutical manufacturing systems provided with environmental containment are provided. Certain vessels, unit operations, devices, and components may be used to perform all or part of biological, chemical, and/or pharmaceutical manufacturing processes therein. In some embodiments, an environmental containment system includes a multi-level containment apparatus. For instance, a first substantially closed environmental containment enclosure may be contained within a second substantially closed environmental containment enclosure; the first and second enclosures may be contained in a third substantially closed environmental containment enclosure, etc. Each of the environments within the substantially closed environmental containment enclosures may be controlled independently, and leakage of any materials from an inner system may be contained by an outer system.

10. An apparatus comprising:
-
at least one device comprising a vessel or a processing device having an outer surface and an interior portion configured for containing a fluid or biological cells; a first environmental containment enclosure having an inner surface and configured for surrounding at least a portion of the vessel or the processing device, the inner surface of the environmental containment enclosure and the outer surface of the vessel or the processing device defining a first enclosed space therebetween, said first enclosed space not in continuous fluid communication with the interior portion of the vessel or the processing device; a second environmental containment enclosure surrounding at least a portion of the first environmental containment enclosure, the second environmental containment enclosure having an inner surface, the inner surface of the second environmental containment enclosure and the outer surface of the first environmental containment enclosure defining a second enclosed space therebetween, said second enclosed space not in continuous fluid communication with the interior portion of the vessel or the processing device, and wherein said first and said second enclosed spaces are each maintained during use of the vessel or the processing device at a pressure chosen independently from greater than atmospheric pressure, less than atmospheric pressure, and equal to atmospheric pressure; an environmental treatment system in communication with at least one of the first and second enclosed spaces, the environmental treatment system comprising a ventilation system in fluid communication with at least one of the first and second enclosed spaces the ventilation system comprising an inlet port dimensioned for connection to a source of gas unit for introducing gas into the apparatus and an outlet port for connection to an exhaust unit for removing a gas from the apparatus; and a damper control configured for connection to at least one of the source of gas unit and the exhaust unit, the damper control operably connected to the apparatus and capable of regulating pressurization within the first and the second enclosed space of the apparatus; and
wherein the environmental treatment system and the first and second environmental containment enclosures are configured to maintain an aseptic and/or substantially particle-free environment within the at least one of the first and second enclosed spaces. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
