Dialyzer, system and dialysis method
First Claim
1. A dialyzer comprising a vertical central shaft, a lower clamp unit adjustably and selectively fixedly mounted to said shaft,an upper clamp unit adjustably and selectively fixedly mounted on said shaft,said lower clamp unit comprising a lower clamp block having sides, and a clamp bar attached to and opposed to each of said sides, each of said bars being selectively clampable against said side, and circulating pumping means in said lower clamp block comprising an opening through said lower clamp block, said opening being slanted, said upper clamp unit comprising an upper clamp block having sides, a bar opposed to each of said sides, a plurality of vertically aligned grooves in each of said bars and each of said sides, each of said grooves in a said bar being opposed to a said groove in said block side to form a vertical channel when said bar is clamped to said block.

Abstract
A dialyzer and a dialysis system particularly adapted to fast dialysis and avoidance of contamination or spillage. Adjustable upper and lower clamp units are provided on a central shaft. Means are provided to securely mount a plurality of dialysis bags around the entire periphery of the clamping units and to provide adequate bath circulation through the relatively confined core volume. The individual dialysis bag may be accurately filled or emptied while in a fully installed position on the dialyzer. The circulating pump is a pair of openings in the bottom clamp unit. The top of each bag is always open to receive a syringe needle. The rotating motor is isolated from the bath.

1. A dialyzer comprising a vertical central shaft, a lower clamp unit adjustably and selectively fixedly mounted to said shaft,
an upper clamp unit adjustably and selectively fixedly mounted on said shaft, said lower clamp unit comprising a lower clamp block having sides, and a clamp bar attached to and opposed to each of said sides, each of said bars being selectively clampable against said side, and circulating pumping means in said lower clamp block comprising an opening through said lower clamp block, said opening being slanted, said upper clamp unit comprising an upper clamp block having sides, a bar opposed to each of said sides, a plurality of vertically aligned grooves in each of said bars and each of said sides, each of said grooves in a said bar being opposed to a said groove in said block side to form a vertical channel when said bar is clamped to said block.
- 12. A method of dialysis comprising providing a vertically aligned array of a plurality of dialysis bags around the complete periphery of a dialyzer mounting means, rotating said dialyzer mounting means and said array of bags in a dialyzer bath, said rotation of said monting means providing a circulating pumping action of liquid contained in said bath upwardly into that volume of said bath bounded on the sides by said array of dialyzer bags by causing an inclined opening in the bottom of said mounting means to circulate dialyzer bath liquid into the volume of bath liquid bounded by said array of dialyzer bags.
