The present disclosure relates to Oxygen Reduction Disposable kits (ORDKit), devices and methods for the improved preservation of whole blood and blood components. The improved devices and methods for the collection of blood and blood components provide for whole blood and blood components having reduced levels of oxygen. The devices and methods provide for the rapid preparation of deoxygenated blood and blood components for storage that improves the overall quality of the transfused blood and improves health outcomes in patients.

Described are embodiments that include methods and devices for separating components from multi-component fluids. Embodiments may involve use of separation vessels and movement of components into and out of separation vessels through ports. Embodiments may involve the separation of plasma from whole blood. Also described are embodiments that include methods and devices for positioning portions, e.g., loops, of disposables in medical devices. Embodiments may involve use of surfaces for automatically guiding loops to position them into a predetermined position.

A system and method for pumping fluid using a set of interconnected pump cassettes is disclosed. Each of the pump cassettes can receive a first solution in a first pumping chamber and each of the pump cassettes can receive separate second solutions in respective second pumping chambers, so that the first solution can be mixed with the separate second solutions, each said mixture capable of being placed in separate containers. The system includes a control assembly for operating each pump cassette, each pump cassette having a flexible membrane to pump fluid into and out of the pumping chambers, and each pump cassette configured for mating with a base unit that provides positive or negative pneumatic pressure to the flexible membrane.

Provided are a blood bag system and a blood treatment method capable of securely and efficiently obtaining a medium specific gravity blood component having a sufficiently low content rate of a light specific gravity blood component. In a blood bag system (10) used for a blood treatment method, in a transfer completed state in which whole blood in a first bag (12) is centrifuged to transfer blood plasma to a second bag (14) through a first transfer tube (24) and transfer red cell concentrates to a third bag (16) through a second transfer tube (26), a buffy coat is left in the first bag (12). In the transfer completed state, when a platelet added solution is transferred from a fourth bag (18) to the first bag (12) on which a centrifugal force acts through a third transfer tube (28), blood plasma in the buffy coat is discharged from the first bag (12).

Disclosed is a bioprocessing system comprising apparatus (200) including a centrifugal separation housing (210) having a temperature controllable compartment (215) for removably accepting a separation chamber (50), the apparatus further comprising at least one mixing station (250) for supporting one or more fluid storage vessels (10, 20, 30, 40), the station including a temperature controllable area (252) for increasing or decreasing the temperature of the contents of the or each supported vessel. The system further includes a disposable fluidic arrangement (100) including a centrifugal separation chamber (50) removably mountable within the compartment (215) and having one or more ports (52) allowing fluid ingress into, or egress out of the chamber, via the one or more ports in use, said ports being in fluid communication with one or more of said fluid storage vessels via fluid conduits (12, 22, 32, 42) and via one or more valve arrangement.

Embodiments for a portable and compact centrifugation and thermal management system capable of separating and transporting biological samples while maintaining sample quality for periods of shipment time are described. A compact, automatic centrifuge holding exactly one sample tube is inside an insulating and thermally managed container suitable for standard shipping. A rotor to retain a sample tube is pre-balanced. An electronic controller starts, times and stops centrifugation automatically, responsive to placement of a lid. Thermal management may comprise a phase change material. Embodiments are free of user controls. Embodiments are free of the need for external power or external control.

A cell processing system includes a processor connectable to a source container filled with a biological fluid, the processor including a separator configured to separate the biological fluid from the source container into at least two streams according to a process including at least one process parameter, and a controller coupled to the processor and an input. The controller is configured to receive the at least one process parameter, to evaluate the process using the at least one process parameter before performing the process, and to carry out one or more actions based on the evaluation, such as providing an output estimate to the operator, preventing the process from being performed according to a comparison between a calculated condition and a control, or providing an error indication to the operator according to the calculated condition and a measured in-process condition.

A method is provided for controlling fluid flow through a tubing segment is provided in which a pump draws fluid through the tubing segment using negative pressure P. The method includes the steps of: a) operating the pump at an initial commanded fluid flow rate to draw fluid through the tubing segment; b) measuring on a continuous basis the P in the tubing segment; c) determining into which of four zones the measured P falls, a first zone being where P>X.sub.1, a second zone being where X.sub.1>P>X.sub.2, a third zone where X.sub.2>P>X.sub.3, and a fourth zone where X.sub.3>P; d) if P is in the first zone for greater than a first pre-established time period, then increasing the commanded flow rate of the pump and returning to step b); e) if P is in the second zone, then continuing to operate the pump at the flow rate at which the pump is currently operated and returning to step b); f) if P is in the third zone, for greater than a second pre-established time period, then decreasing the commanded flow rate of the pump and returning to step b); and g) if P is in the fourth zone, then commanding the pump to stop. A system including a programmable controller configured to automatically perform the method is also disclosed

A screen exchange device for reducing the size of a biological tissue according to one embodiment comprises: a disk comprising a plurality of screens each having at least one through-hole configured to reduce the size of a biological tissue, the screens having different through-hole characteristics; a first cover which covers a first side of the disk and includes a first opening through which a biological tissue passes; a second cover which covers a second side of the disk and includes a second opening through which the biological tissue passes; a housing configured to receive the disk; and a manipulator which selects any one screen among the plurality of screens and manipulates the first cover or the second cover such that the selected screen communicates with the first opening and the second opening.
