Abstract
A dialysis module for use with a variety of single pass or single pass-recirculating artificial kidney dialyzers as desired. The apparatus has quick disconnects to allow attachment of a single pass kidney dialyzer or shunt tube so that a single housing can be used to provide two entirely different modes of operation as selected. A clear canister forms a part of the dialysis flow path in both modes of operation to enable rapid detection of blood leaks in either mode of operation.
