A blood component separation device for separating a plurality of blood components from blood sampled from a blood donor, and collecting platelets, includes: an operation unit that calculates a predicted platelet recovery rate from a hematocrit value of the blood and a platelet concentration of the blood, and calculates a recommended processing amount of the blood recommended for collecting a target number of units of platelets on the basis of the calculated predicted platelet recovery rate, wherein the operating unit sets the predicted platelet recovery rate calculated from any the hematocrit value and any the platelet concentration to be smaller by a predetermined value a when the blood donor is female than that when the blood donor is male.

The inventive apparatus is a device for collecting a target volume of blood in a collecting bag connected to a collection needle with a flexible tube. The device has a plate for the collecting bag and a clamping device for clamping the flexible tube. The device also has a bearing element having a bearing surface, and a clamping element with a clamping surface. The clamping element is able to move between an open position in which the flexible tube positioned between the bearing and clamping surfaces is not deformed and a closed position in which the flexible tube positioned between the bearing and clamping surfaces is closed off. The device also has a control unit configured to determine the volume of blood collected and move the clamping element from the open position to an intermediate position, when the determined volume of blood collected reaches a predetermined volume.

A blood component sampling cassette which can be more efficiently manufactured at lower cost as compared to a typical cassette, a blood sampling circuit set, and a blood component sampling system. A blood component sampling cassette (22) includes a cassette main body (23) made of a soft material to which heat sterilization is applicable. The cassette main body (23) is provided with a retransfusion line (44). The retransfusion line (44) is provided with a reservoir (47) configured to temporarily store a blood component to be returned to a blood donor. The reservoir (47) is pressed by a retransfusion pump (49) to discharge the blood component from the reservoir (47).

The object of the invention is to provide a blood separation device that can reduce the total time for drawing blood to obtain high-concentration platelet liquid, thereby reducing the binding time of the blood donor. The device includes a temporary storage bag (Y2) (also serves as a buffy coat bag) which is a whole blood bag for storing whole blood drawn from a blood donor. The controlling unit of the device controls the device to draw whole blood from the blood donor in parallel with at least either a circulation flow step or an acceleration step, thereby storing the drawn whole blood in the temporary storage bag (Y2).

A system for altering blood flowrate during donation comprising a height adjustable blood collection assembly including: a base, a tower extending upward from the base, an actuator and a carrier; the actuator is coupled to the carrier and the tower, and the actuator vertically adjusts the carrier relative to the base; a receptacle being connected to the carrier and configured to receive a blood collection container; and a controller that interacts with at least the actuator.
