A centrifugal separation system includes a blood bag system and a centrifugal separation and transferring device. The blood bag system is equipped with a single clamp that is mounted over a second tube and a third tube. In a first blocking portion of a first insertion hole of the clamp, a portion thereof except for a portion connected with a first opening portion is closed by a main body. On the other hand, a second insertion hole of the clamp includes a tube detaching portion, that is connected with a second blocking portion and that enables the third tube to be detached from the main body.

A blood bag system includes one clamp mounted over a second tube and a third tube. In a first insertion hole of a main body of the clamp, a portion of a first blocking portion excluding a portion connected with a first opening portion is closed by the main body. The main body can be deformed from a first state to a second state. In the first state, the third tube having been moved into a second blocking portion of a second insertion hole is restrained by the second blocking portion. In the second state, the third tube can be moved from the second blocking portion to a position that is other than a second opening portion and in which a third flow path of the third tube is reopened.

Apparatus and methods for providing extracorporeal blood circulation and oxygenation control include seven-stage de-airing of blood to provide automated cardiopulmonary replacement to sustain patient life during a medical procedure comprising repairing or replacing the heart valve in a patient.

Systems and methods are provided for depleting platelets from blood. The system includes a multi-stage blood separation chamber in which blood is separated into red blood cells and platelet-rich plasma. The platelet-rich plasma is conveyed from a first stage of the chamber to a second stage, where it is separated into platelets and platelet-poor plasma. The platelet-poor plasma is conveyed out of the chamber while the platelets are allowed to accumulate in the second stage of the chamber. When a controller of the system has determined that the maximum chamber capacity of platelets has been accumulated in the second stage of the chamber, the platelets are conveyed out of the chamber to a waste container. The cycle of separating blood into its components, accumulating platelets in the chamber, and then flushing the platelets from the chamber is repeated until a target platelet concentration of the blood is achieved.

A blood bag system includes a BC pooling bag for centrifugation of a buffy coat, a filter for removing white blood cells from a supernatant liquid transferred from the BC pooling bag, a platelet preserving bag for reserving the supernatant liquid that has passed through the filter, a first tube connecting the BC pooling bag and an inlet of the filter, a second tube connecting the platelet preserving bag and an outlet of the filter, and a cassette to be fixed in the centrifugation and separation apparatus. The first tube and the second tube are disposed within the cassette. The cassette includes a first clamp section for closing and opening the first tube, and a second clamp section for closing and opening the second tube.

A method for prophylaxis or treatment of a graft's rejection of a recipient, driven and adjusted by a microprocessor-based controller. Provided is a fluid circuit comprising a first container configured to receive a transplant component and a second container configured to receive an apoptotic component. Provided is a separator configured to associate with the fluid circuit and separate whole blood into a red blood cell component, a plasma component, and a white blood cell component. Whole blood is directed into the fluid circuit and the separator. The whole blood is separated into the red blood cell component, the plasma component, and the white blood cell component. A first portion comprising the transplant component of the white blood cell component is directed to the first container. A second portion of the white blood cell component is directed to the second container and the second portion is rendered apoptotic.

A processing system includes a processor including a separator, a set configured to cooperate with the separator to separate whole blood into plasma and other components, the set including an inlet line attachable to a patient to receive whole blood and an return line attachable to a patient to return processed fluid, and a source of replacement fluid connected to the disposable set, the processor configured to combine the other components with replacement fluid to define the processed fluid. The processor includes a controller and an input device coupled to the controller, the controller configured to receive an input via the input device, the input representing a volume of replacement fluid, and to control the processor to separate whole blood passing through the set and to combine the other components with the replacement fluid according to the input until the source of replacement fluid is empty.

A method for washing platelets includes introducing anticoagulant into a platelet product container, drawing re-anticoagulated platelet product from the platelet product container, and introducing it into a centrifuge bowl. The centrifuge bowl separates the platelets from the supernatant in which they are suspended. The method then washes the platelets by introducing wash solution into the centrifuge bowl. As the wash solution is introduced into the bowl, it displaces the supernatant from the bowl and into a waste container. The method then introduces platelet additive solution into the centrifuge bowl, which displaces the wash solution from the centrifuge bowl and into the waste container and further wash the platelets. The method then repeatedly accelerates and decelerates the centrifuge bowl to resuspend the platelets in the platelet additive solution.

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.
