Abstract: A pair of elongated jaw members are provided and interconnected at one pair of corresponding ends in generally parallel relation through the utilization of an open loop member having opposite ends formed integrally with the adjacent jaw member ends. The jaw members and the loop member are constructed of stiff but resilient plastic and one of the jaw members includes an integral arm projecting laterally outwardly therefrom across the adjacent end of the other jaw member. The arm includes longitudinally spaced ratchet teeth thereon with which the adjacent end of the other jaw member is selectively engageable and the included angle formed between the one jaw member and the arm is slightly less than 90.degree., the connection between the arm and the one jaw member end from which it is supported being sufficiently deformable to allow angular displacement of the arm to a position with the included angle formed between the arm and the one jaw member exceeding 90.degree..

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.

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 blocking off of a portion of a fluid conduit when a coil dialyzer is used so that a single housing can be used to provide two entirely different modes of operation as selected. A clear canister preferably 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. An aspirator is associated with a recirculating pump to provide negative pressure to dialysate in the flow path when a single pass dialyzer is used while only the recirculating pump is necessary during single pass-recirculating dialysis.
