System and Method for Continuous Separation of Whole Blood

摘要

An apparatus for separating whole blood includes a continuous flow separation device in which drawn whole blood is separated into a first and second blood component. The separation device has an inlet for introducing whole blood into the separation device, a first blood component outlet for withdrawing the first blood component, and a second blood component outlet for withdrawing the second blood component. The apparatus also includes a first blood component storage container connected to the first blood component outlet, and a first blood component pump to draw the first blood component from the separation device. Additionally, the apparatus can have second blood component storage container connected to the second blood component outlet, and a controller for controlling fluid flow through the apparatus. The controller monitors the total volume of whole blood drawn from the source, and stops a draw pump when the target whole blood volume is withdrawn.

主权项

1. An apparatus for separating whole blood comprising:
an access device through which whole blood is drawn from a source; a continuous flow separation device in which the drawn whole blood is separated into a first blood component and a second blood component, the continuous flow separation device having an inlet for introducing whole blood into the continuous flow separation device, a first blood component outlet for withdrawing a first blood component, and a second blood component outlet for withdrawing a second blood component; a draw line fluidly connecting the access device and the continuous flow separation device; a draw pump that draws whole blood from the source through the access device and draw line and into the continuous flow separation device; a first blood component storage container fluidly connected to the first blood component outlet; a first blood component pump configured to draw the first blood component from the continuous flow separation device and into the first blood component storage container; a final first blood component storage container fluidly connected to the first blood component outlet; a second blood component storage container fluidly connected to the second blood component outlet; and a controller for controlling fluid flow through the apparatus, the controller controlling operation of the draw pump and monitoring a total volume of whole blood drawn from the source, the controller configured to stop the draw pump when the target whole blood volume is withdrawn.
