Abstract
A tubing set for a blood processing system includes a first connector, a first tube, and a second tube. The first connector is configured to connect to a separation device within the blood processing system, and has a first inlet configured to be fluidly connected to an outlet of the separation device. The first connector also has an outlet and a second inlet. The first tube fluidly connects to the outlet and fluidly connects the separation device and a blood component storage container. The second tube is fluidly connected to the second inlet and fluidly connects the separation device and a saline storage container. The second tube may include a second connector that connects to the saline storage container.
Core Innovation
The invention describes a tubing set for a blood processing system, with a first connector configured to connect directly to a centrifuge bowl. A first tube connects the bowl to a final blood component storage container, while a second tube connects the bowl to a saline storage container. The disclosed set routes fluid from the bowl to these separate destinations.
The document also describes a connector with a first port configured to connect to the centrifuge bowl outlet and second and third ports connected to tubes leading to the blood component and saline storage containers. The tubing and connector refinements include a cap, a sample site, a pre-curved collection tube, and tube markings or color coding. These features are described as intended to reduce kinking and setup errors and ease installation.
Claims Coverage
The two independent claims cover two inventive features: a tubing set connected to a centrifuge bowl and a connector that provides fluid connections from the bowl to blood component and saline storage containers.
Tubing set with separate blood component and saline paths
Claim 1 covers a first connector configured to connect directly to a centrifuge bowl, a first tube fluidly connected to the connector outlet and configured to connect the bowl to a final blood component storage container, and a second tube fluidly connected to a second inlet and configured to connect the bowl to a saline storage container. Described refinements include tube markings or color coding, a cap, a sample site, connector flow-path geometry, and a plasma container.
Connector with ports for blood component and saline paths
Claim 27 covers a connector body with a first port configured to connect directly to the centrifuge bowl outlet, a second port fluidly connected to the first port and configured to connect to a tube leading to a final blood component storage container, and a third port fluidly connected to the first port and configured to connect to a tube leading to a saline storage container. Described refinements include a cap, flow-channel geometry, port placement, and a plasma container.
The independent claims cover a tubing set and a connector that route fluid from a centrifuge bowl to blood component and saline storage containers. The described dependent-claim refinements add cap, tubing, sample-site, port, and flow-channel features.
Stated Advantages
The connector and tubing features are intended to reduce kinking and setup errors.
The connector and tubing features are intended to ease installation.
Documented Applications
A disposable tubing set for a blood-apheresis or blood-processing system, routing fluid from a centrifuge bowl to a blood component storage container, including a plasma container, and a saline storage container.
