<P>PROBLEM TO BE SOLVED: To provide a platelet-rich-plasma (PRP) separator-concentrator comprising a housing, a PRP separation assembly, and a PRP concentration assembly. <P>SOLUTION: In the PRP separator-concentrator, a concentration assembly has a concentration tank, an outlet tube is secured to the housing 2, a separation assembly forms a combined separator-concentrator assemblage 11 that is rotatable about the outlet tube. The separation assembly includes a separation chamber lined with a depth filter having pores and passageways that are sized to receive and entrap erythrocytes during centrifuging. The concentration chamber has a floor for supporting desiccated beads and a wall with at least one opening closed with a screen. PRP concentrate is produced by contacting PRP with desiccated beads while the beads are stirred with a stationary rake, and rotating the concentration chamber at centrifugal speeds. <P>COPYRIGHT: (C)2012,JPO&INPIT |
