The cell-trans system is nothing like the Orthopat, 1st of all the Orthopat is used both intraoperatively AND postoperatively. Secondly, the Orthopat system uses centrification to 1st "spin" out ALL blood components except the RBC's. Then goes through another "spin" cycle and washes RBC's with .9 % NACL. The Orthopat performs better than systems such as the Haemonetics CS5 etc. with higher HCT's.
