Abstract

See full text

A cell washing apparatus is provided to wash a cell-containing fluid. The apparatus is arranged to exchange one or more exchangeable entities from a cell-containing first fluid, and comprises, a first fluid conduit and a second fluid conduit, the second fluid conduit separated from the first fluid conduit by a semi-permeable membrane disposed therebetween; the first fluid conduit having a first fluid inlet and a first fluid outlet, the first fluid conduit arranged to transport the first fluid in a first direction between the first fluid inlet and the first fluid outlet; the second fluid conduit being arranged to house a second fluid; wherein the semi-permeable membrane comprises a plurality of pores arranged to permit transport of said one or more exchangeable entities from the first fluid to the second fluid; wherein the one or more exchangeable entities comprise free haemoglobin and/or blood plasma; and wherein the first fluid is whole blood isolated from a human body, or packed red blood cells. The cell washing apparatus of the present invention aims to solve the problem of harmful species that accumulate in a cell-containing fluid (such as, for example, transfusion blood) during storage and other applications, in which it is desired to transfer red blood cells to a clean suspending liquid.
