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.

1. A method for washing platelets comprising:
(a) introducing anticoagulant into a platelet product container containing platelet product, the platelet product containing platelets suspended within a supernatant; (b) drawing anticoagulated platelet product from the platelet product container; (c) introducing the anticoagulated platelet product into a centrifuge bowl and centrifuging the anticoagulated platelet product to separate the platelets from the supernatant; (d) introducing a wash solution into the centrifuge bowl, the wash solution displacing the supernatant from the bowl into a waste container; (e) introducing platelet additive solution into the centrifuge bowl, the platelet additive solution displacing the wash solution from the centrifuge bowl into the waste container; (f) jogging the centrifuge bowl by accelerating and decelerating the centrifuge bowl; (g) repeating step (f) at least once to resuspend the platelets in the platelet additive solution.
