Abstract: A blood processing assembly is described. The assembly comprises a separation element (16) for separating blood from a source and a fluid path (18) for conveying blood from the source to the separation element (16). The fluid path (18) includes an in-line cassette (22) having a housing (110) defining an interior, first (T4) and second (T5) pump ports on the housing (110), a first flexible tubing loop (134) extending between the first and second pump ports externally of the housing for engagement with an external peristaltic pumping element (292), a liquid port (T1 to T3,T8 to T10) on the housing attachable to a length of tubing (154) that extends externally of the housing and forms a part of the associated fluid path (18), liquid passages (F1 to F19) formed within the housing and communicating with the liquid port, the first pump port and the second pump port, and valve means (V1 to V10) formed within the housing for controlling liquid flow through the liquid passages and through the associated fluid path. The cassette also comprises a pressure sensing chamber (S1 to S4) which is formed within the housing and communicates with at least one liquid passage (F1 to F19). The sensing chamber (S1 to S4) includes means for transmitting liquid pressure present within the liquid passage to an external sensing element (PS1 to PS4).

Abstract: A peristaltic pump tube holder has a body having first and second pump tube connectors extending outside of it. The pump tube connectors extend at an acute angle relative to a surface of the body to receive a flexible tubing loop and orient the tubing loop for engagement with an external peristaltic pump rotor.

Abstract: A device and method are provided for separating mononuclear cells from red blood cell depleted plasma in a centrifuge blood cell separator. The device includes an inlet for receiving plasma, an area for receiving mononuclear cells, and an outlet for receiving mononuclear cell depleted plasma. The distance and flow path between the inlet and outlet being so constructed and arranged as to cause mononuclear cells to sediment out into the area for receiving the mononuclear cells and causing at least 66% of the platelets contained in the plasma to flow to and through the outlet.
