<p>A system for collecting platelets. Whole blood is removed from a patient (10) and directed to a hemoconcentrator (22) having a blood inlet (24), a blood outlet (26), a blood passage communicating with the blood inlet (24) and blood outlet (26), an ultrafiltrate outlet (28) and a membrane separating the blood passage from the ultrafiltrate outlet (28). The blood is passed through the blood passage of the hemoconcentrator (22) while a negative pressure is applied to the ultrafiltrate outlet (28). After a period of time, the negative pressure is terminated, and the concentrated platelets from the hemoconcentrator (22) are flushed and directed to a platelet collection container (44).</p> |
