  • Portable hemodialysis system
    Patent number: 4083777
    Abstract: A portable hemodialysis system wherein blood and dialysate are pumped in the extracorporeal flow circuit by peristaltic compression of the blood and dialysate flow lines to provide high frequency pulsatile flows in the respective fluid lines. The pulsatile flows of blood and dialysate are passed through the dialyzer to reduce fluid film mass transfer resistance therein and enhance the dialyzing efficiency of the hemodialysis system.
