<p>Disclosed is a leukocyte-removing filter device comprising (a) a casing having an inlet for blood and an outlet for leukocyte-removed blood, which are both located in a top portion of the casing, and (b) a filter medium disposed in the casing so as to divide the internal space of the casing into an inlet-side chamber communicated with the inlet and an outlet-side chamber communicated the outlet. By virtue of the locations of the inlet and outlet on the top portion of the filter device, the leukocyte-removing filter device of the present invention is advantageous not only in that the filter device can be fittedly and stably accommodated into a centrifuge cup together with a plurality of blood bags and circuit tubes connecting the filter device and blood bags, so that a centrifugation can be efficiently conducted without the danger of damaging the filter device and the blood bags, but also in that the operation of expelling the air from the filter by filling the filter with blood can be very readily conducted simply by allowing blood to flow into the filter without any additional burdensome operations. The leukocyte-removing system comprising the above-mentioned leukocyte-removing filter device is also disclosed.</p> |
