| Outline of Final Research Achievements |
A novel portable heart-lung machine called Emergency Life Support System has been developed using the sequential flow pump which was designed as a built-in blood pump with a new principle of two-stage centrifugal pressurization in one impeller. The hydrodynamic performance at 5L/min against 350mmHg of pump head was obtained at 3,100 rpm, and the pump efficiency was about 14%.
To fabricate a highly stable polymer membrane with blood-compatibility on silicone hollow fibers for oxygenator, a newly designed random copolymer, which consists of phospholipids, siloxane, and cross-link polymers was synthesized. Protein adsorption was suppressed on the polymer-coated silicone surface, and the effect was maintained for 84 days.
