Abstract: A self-loading peristaltic pumping apparatus includes a pump race for receiving a tubing loop, a pump rotor carrying a roller, and a drive mechanism for rotating the rotor within the pump race. The apparatus also includes a roller locating mechanism that moves the pump roller between a retracted position, free of contact with the received tubing loop, and an extended position, at least partially within the pump race for operative contact with the received tubing loop. The apparatus includes at least one tubing guide element carried by the rotor. The guide element extends from the rotor at least partially into the pump race. The guide element serves during rotation of the rotor with the roller in its retracted position, for contacting the received tubing loop to orient the tubing loop within the pump race.

Abstract: A peristaltic pump tube holder includes a body that supports a flexible tubing loop in an erect, outwardly bowed position extending from the body for engagement with a peristaltic pump rotor. The holder also includes a receptacle carrying the body. The receptacle includes a wall forming a chamber that covers the flexible tubing loop and at least partially shields it from contact. The chamber further serves, during engagement between the tubing loop and a peristaltic pump rotor, as a cover for the peristaltic pump rotor.

Abstract: Blood processing systems and methods separate blood into constituents including a plasma constituent that includes a platelet volume. The systems and methods detect the optical density of the plasma constituent and generate a first output indicative of the optical density. A processing element integrates the first output relative to the volume of plasma constituent and generates an integrated output. The integrated output correlates to the platelet volume. A second processing element generates an output based, at least in part, upon the integrated output, which comprises a value indicating a blood volume that needs be processed to obtain a desired platelet volume.
