Abstract:
Automated systems and method for processing blood and other fluids are disclosed. The system and methods utilize a disposable fluid circuit fig. 1 mounted on a re-usable hardware component or module 12. The system withdraws blood from a donor or patient 100, separates the blood into two or more components and further processes or treats the separated component.
Abstract:
Automated systems and methods for withdrawing and replacing fluids in a patient are disclosed. The system withdraws blood from a donor or patient, separates the blood into two or more components and collects the separated component. A replacement fluid capable of at least partially providing the biological function of the separated component is infused into the patient.
Abstract:
A blood separation system (10) is described. The system comprises a device (14, 18) which, in use, operates to separate whole blood into red blood cells and plasma, a whole blood inlet line (290) for conveying a flow of whole blood into the device, a plasma collection line (292) for conveying a flow of plasma from the device, and a red blood cell collection line (294) for conveying a flow of red blood cells from the device. A first sensing assembly (334) including a first sensor in the plasma collection line is provided which in use operates to detect a characteristic of plasma in the flow of plasma and to generate a first output. A second sensing assembly (336) including a second sensor in the red blood cell collection line is provided which in use operates to detect a characteristic of red blood cells in the flow of red blood cells and to generate a second output. A controller (16) operates to control flows in the plasma collection line and the red blood cell collection line based upon the first and second outputs.
Abstract:
A multiple function pump station (PPN) performs different on-line processing tasks. The pump station can be operated in one mode to draw blood from a donor and can in another mode be operated to return blood to the donor. The pump station used to draw blood from a donor can also be used to perform subsequent blood processing tasks, such as mixing processing or additive fluids with the blood, or transferring a harvested blood component to a storage container, or finishing the processing of a harvested blood component, e.g., by passage through a filter (200) to remove leukocytes.
Abstract:
Blood processing systems and methods employ two sensors (334, 336), one (334) to detect a condition of plasma exiting a separation device (18) and another sensor (336) to detect a condition of a cellular component exiting the separation device (18). The first sensor (334) detects, e.g., contamination of the plasma due to the presence of unwanted cellular components. The second sensor (336) detects, e.g., dilution of the cellular component due to presence of plasma. Blood processing parameters are carried out based, at least in part, by conditions detected by one or both of the sensors (334, 336).
