Abstract
New hemofilter (HF) has been manufactured for concentration of priming blood in cardiopulmonary bypass (CPB). Priming of this HF which is hollow fiber type, is 75ml.. Materials of fibers are polymethyl metacrylate. UFR is 22ml./hour/torr (Bovine blood, 25°C, Ht25%, TP3.0g/dl). Quality test was performed with remaining human blood after CPB (n=5). When the blood was concentrated until mean value of 68.8±19.0%, absolute sieving coefficients (SCOE) in free Hb was 10.9±3.0% and in TP was 2.9±0.9% (p<0.01). This HF has high UFR and filtration performance of free Hb.
But SCOE of fee Hb is not yet satisfactory, we will improve the SCOE of free Hb.
