System and Method For Automated Platelet Wash

摘要

A method for washing platelets includes introducing anticoagulant into a platelet product container, drawing re-anticoagulated platelet product from the platelet product container, and introducing it into a centrifuge bowl. The centrifuge bowl separates the platelets from the supernatant in which they are suspended. The method then washes the platelets by introducing wash solution into the centrifuge bowl. As the wash solution is introduced into the bowl, it displaces the supernatant from the bowl and into a waste container. The method then introduces platelet additive solution into the centrifuge bowl, which displaces the wash solution from the centrifuge bowl and into the waste container and further wash the platelets. The method then repeatedly accelerates and decelerates the centrifuge bowl to resuspend the platelets in the platelet additive solution.

主权项

1. A system for automated platelet washing comprising:
a sterile connection for connecting a platelet product container to the system, and withdrawing platelet product from the platelet product container; a centrifuge bowl for separating the platelet product into platelets and a supernatant, the centrifuge bowl configured to send the supernatant to a waste container; a wash solution source fluidly connected to the centrifuge bowl and configured to send wash solution to the centrifuge bowl; a platelet additive solution source fluidly connected to the centrifuge bowl and configured to send platelet additive solution to the centrifuge bowl; and a controller for controlling the operation of the centrifuge bowl, the controller accelerating and decelerating the centrifuge bowl multiple times to resuspend the platelets within the platelet additive solution after the platelet additive solution is added to the platelets and the supernatant is sent to the waste container.
