    摘要: A blood processing device for collecting and exchanging blood components includes a venous-access device for drawing whole blood from a subject and returning unused blood components to the subject. The system may also include a blood component separation device that separates the drawn whole blood into a first blood component and a second blood component. The blood component separation device may also be configured to send the second blood component to a second blood component storage container. The system may use a return line that fluidly connects the venous-access device and the blood component separation device to return the first blood component to the subject. The system may also have a first and second pressure sensor located on the return line. The first pressure sensor may be located between the blood component separation device and the venous-access device and may determine a first pressure within the return line. The second pressure sensor may be located on the return line between the first pressure sensor and the venous-access device and may determine a second pressure within the return line. A pump connected to the return line may control the return flow rate within the return line based on a subject access pressure determined based on the first pressure and the second pressure.

    摘要: A blood processing system for collecting and exchanging blood components includes a venous-access device for drawing whole blood from a subject and returning blood components to the subject. The system may also include three lines connecting the venous access device to a blood component separation device and an anticoagulant source. A blood draw line fluidly connects to the venous-access device to the blood component separation device. An anticoagulant line connected to an anticoagulant source, introduces anticoagulant into the drawn whole blood. A return line, fluidly connected to the venous-access device and the blood component separation device, and returns uncollected blood component to the subject. A draw pump, an anticoagulant pump, and a return pump, respectively control the flows through the draw line, anticoagulant line, and the return line. The blood component separation device separates the drawn blood into a first blood component and a second blood component. The blood component separation device also may be configured to send the first blood component to a first blood component bag.

    摘要: A method and apparatus for collecting plasma reduced platelets potentially suspended in a synthetic solution from a donor. Whole blood is drawn from the donor and introduced into a separation chamber. Platelets are extracted from the separation chamber into a container, using, for example, surge (with anticoagulated plasma or a synthetic solution) or push methodologies. The remaining blood components in the separation chamber are returned back to the donor. The steps of drawing whole blood and introducing the whole blood into the separation chamber, extracting platelets from the separation chamber into the container, and returning the remaining components in the chamber back to the donor are repeated. The sequestered platelets in the container are reintroduced into the separation chamber, whereupon a plasma reduced platelet product is extracted.

    摘要: Automated filtration of whole blood or blood components is accomplished in a manner that ensures consistent flow or pressure characteristics through the filter. A feedback circuit monitors pressure in the vicinity of the filter inlet and controls operation of a fluid pump that sends one or more unfiltered blood components into the filter. Using this arrangement, a variety of parameters relating to filtration efficacy can be precisely controlled, including flow rate, flow pressure, and average pressure over a predetermined volume. The system may provide an alarm or automatic cut-off in the event a maximum value of one of the parameters is reached or exceeded. The system is also capable of serially filtering multiple blood products through the single filter and accommodating different flow or pressure characteristics associated with each such product.

    摘要: The invention is directed to a centrifugation bowl with a rotating core. The centrifugation bowl includes a rotating bowl body which defines a primary separation chamber. The core, which is generally cylindrically shaped and is disposed within the bowl body, defines a secondary separation chamber. A stationary header assembly may be mounted on top of the bowl body through a rotating seal. The stationary header assembly includes an inlet port for receiving whole blood and an outlet port from which one or more blood components are withdrawn. The inlet port is in fluid communication with a feed tube that extends into the primary separation chamber. The outlet port is in fluid communication with an effluent tube that extends into the bowl body. The effluent tube includes an entryway at a first radial position relative to a central, rotating axis of the bowl. The core is arranged at a second radial position that is outboard from the entryway to the effluent tube and includes one or more core passageways for providing fluid communication between the primary and secondary separation chambers. A sealed region is formed at the upper edge of the core relative to its attachment point to the bowl body. Also provided is a method for recovering a whole blood fraction from a donor using the core of the present invention.

    摘要: An integrated, vacuum-driven shed blood processing system that collects, dilutes, filters and washes postoperatively shed blood and concentrates red blood cells for reinfusion to the patient. The location of the centrifuge bowl between the surgical site and the vacuum source used to clean the site allows the immediate collection of shed blood in the bowl without an intermediate reservoir or an additional pump. In conjunction with a modified centrifuge bowl having a sealed aperture in its floor that permits reinfusion directly from the bowl without an additional reinfusion bag or reverse pump, this configuration processes blood for reinfusion using fewer steps and components yet without loss of functionality. Dilution of the blood upon its introduction into the system reduces the tendency to coagulate and allows the use of lower bowl rotation speeds. Slower rotation reduces red blood cell damage and lowers power requirements, which improves portability.

    摘要: A centrifuge bowl for separating whole blood into less dense and more dense components and for collecting both less dense and more dense components without stopping bowl rotation. The fluid pathway from an inlet port to a separation chamber comprises an inlet tube and an introduction passageway. The fluid pathway from the separation chamber to an outlet port comprises a collection passageway. The introduction and collection passageways are nonrotatable. The more dense blood components can be extracted from the bowl during rotation by applying suction at the inlet port or pressure at the outlet port.

    摘要: A system dynamically adjusts the delivery rate of a cryopreservation solution to red blood cells to permit freezing. The delivery rate is preferably determined according to an equation that maintains a linear change of red blood cell osmolarity over time so as to prevent osmolarity shock of the red blood cells. In the preferred embodiment, the system includes a controller that is preconfigured to automatically deliver the cryopreservation solution to the red blood cells in accordance with the equation. The system may also support the recovery of thawed red blood cells by diluting the red blood cells and washing them of the cryopreservative. Again, the system preferably adjusts the delivery rate of a dilution solution so as to prevent osmolarity shock of the red blood cells during the recovery phase. The recovered red blood cells may be suspended in a preservation solution to further increase their shelf-life following the recovery phase.
