Blood line for non-anticoaglant hemodialysis

Abstract

Blood line designed for non- anticoagulant dialysis was prepared, and in its clinical trials with use of KF101 dialyzer, satisfactory result was obtained.
1) By using the double tubing system pressure monitor chamber, it is possible to measure P_BO without contacting blood with air, and to control ultrafiltration.
2) A stream-line shaped air trap--chamber was designed to prevent turbulent blood flow, and a polyester filter-mesh of the air-trap chamber was spray-coated with uniformly hydrophilic HEMA copolymer solution in ethanol so as to inhibit bubble formation on the surface of filter mesh. In this way, the thrombus formation in the system was prevented.
