Abstract

This invention provides a single needle dialysis blood tubing occluder, comprising in a preferred aspect, a pair of pivotly mounted clamping arms having a leaf spring affixed to the non-pivot end of each occluder with the spring in slidable engagement with a symmetrical cam. Means are provided for actuating the cam, whereby the cam moves the tubing occluder to alternately occlude and non-occlude a pair of blood tubings.
