Danaher has filed a patent for an apparatus designed to drain a bioreactor vessel. The apparatus includes a tubular body portion with an interior passageway and at least one aperture for fluid communication. It also features a suction tube that connects to the tubular body portion and a port in the vessel’s sidewall. The method involves arranging the suction tube inside a flexible bioprocessing bag, connecting one end to a suction drain device at the bag’s bottom, and the other end to a port in the sidewall. By activating a pump, fluid is drawn from the bag into the suction tube and out through the port.

An apparatus for draining a bioreactor vessel
A recently filed patent (Publication Number: US20230313110A1) describes a method and system for draining a flexible bioprocessing bag. The method involves arranging a suction tube inside the bag, with one end connected to a suction drain device at the bottom of the bag and the other end connected to a port in the sidewall of the bag. By changing the state of the suction drain device, the interior of the bag is put in fluid communication with the suction tube. Activating a pump then draws fluid from the bag's interior into the suction tube and out of the bag through the port in the sidewall.
The patent also includes additional claims related to the suction drain device. The device consists of a tubular body portion with an interior passageway and at least one aperture for fluid communication. The first end of the suction tube is connected to this tubular body portion. The device may also include a drain flange that creates a space between the bottom of the bag and the flange, allowing fluid to pass into the aperture in the tubular body portion. Furthermore, the device may have a plunger that can be moved between a closed position, where there is no fluid communication, and an open position, where the aperture is in fluid communication with the suction tube.
In addition to the method, the patent also describes a bioprocessing system that includes a vessel and a flexible bioprocessing bag. The system features an apparatus for draining the bag, which includes the aforementioned tubular body portion, suction tube, and optional drain flange. The suction tube is connected to the tubular body portion, while the second end of the suction tube is connected to a port in the sidewall of the bag.
Overall, this patent presents a method and system for effectively draining a flexible bioprocessing bag. By utilizing a suction drain device and a suction tube, the fluid inside the bag can be efficiently drawn out through a port in the sidewall. The additional claims provide further details on the design and functionality of the suction drain device, offering potential improvements to the bioprocessing system.
