ABSTRACT:
Improved means of sealing the ends of tubular permeable membrane material in a dialyzer coil and providing connections to associated inlet and outlet tubing is disclosed. The tubular membrane material is sealed by clamping the ends thereof to the support material which provides an improved flow path of blood into and out of the permeable membrane material eliminating thrombus formation, clotting and flow restrictions within the dialyzer. A simplified and leakproof tubing connector is also disclosed.
