Continuous flow centrifuge for blood component separation
The granted patent US12042595B2 describes a centrifuge bowl designed for the continuous separation of whole blood into two distinct components: a first blood component, which is identified as red blood cells, and a second blood component, which is plasma. The centrifuge bowl features a rotatable outer body and a coaxial top core, with a bottom core that includes a vertically extending wall. This configuration creates a primary separation region where the initial separation of blood components occurs, followed by a secondary separation region. The design incorporates an inlet port for introducing whole blood, along with dedicated outlet ports for extracting the separated blood components. Additionally, the patent outlines various structural elements, such as a rotary seal, fluid pathways, and extraction tubes, which facilitate the efficient operation of the centrifuge.
Further enhancements to the centrifuge bowl include an optical sensor for monitoring the interface between the separated blood components, allowing for controlled extraction of the first blood component. The design also features a weir disk that aids in directing the flow of the second blood component into the outlet port. The patent claims detail the specific configurations and connections between the components, ensuring that the first blood component extraction region is isolated from the primary separation region to prevent contamination. Overall, the invention aims to improve the efficiency and effectiveness of blood component separation in medical applications.
