METHOD AND APPARATUS FOR PRODUCING PLATELET RICH PLASMA AND/OR PLATELET CONCENTRATE

摘要

Platelet rich plasma and/or platelet concentrate is prepared by placing whole blood in a first chamber of a sterile processing disposable having two chambers. The processing disposable is subjected to a first centrifugation to separate red blood cells, and the resulting platelet rich plasma supernatant is decanted to the second chamber. The processing disposable is subjected to a second centrifugation to concentrate platelets. A volume of the platelet poor plasma supernatant in the second chamber is removed, and the platelets are re-suspended in the remaining plasma. The second chamber may contain anticoagulant to preclude aggregation of the platelets.

主权项

1. A method for producing a physiological product of selected composition comprising the steps of:
placing a physiological fluid having a plurality of components in a first chamber of a sterile container having first and second chambers; subjecting said physiological fluid to centrifugation to separate at least one of said components from a first supernatant; decanting said first supernatant to said second chamber; subjecting said first supernatant to centrifugation to separate a second of said components from a second supernatant; removing a predetermined amount of said second supernatant from said second chamber whereby a remainder of said second supernatant is in said second chamber; and re-suspending said second of said components in said remainder of said second supernatant in said second chamber.
