Abstract
Described are embodiments that include methods and devices for separating composite liquids into components. Embodiments involve the use of a flexible membrane for separating a composite liquid into components. The composite liquid may include, in embodiments, a cellular containing liquid, such as whole blood or components of whole blood. In one specific embodiment, the composite liquid is a buffy coat.
Claims11
A disposable blood separation set comprising:
- a blood processing vessel adapted to be mounted on a centrifuge rotor and to separate whole blood into plasma, a buffy coat, and red blood cells;
- a flexible membrane defining a membrane volume, the flexible membrane having a thickness that tapers along its length, wherein an inlet into the membrane volume is in fluid communication with an outlet of the blood processing vessel such that the buffy coat flows into the membrane volume for further separation;
- and
- a cell separation chamber with a side wall defining a chamber volume, wherein the flexible membrane is positioned within the chamber volume.
