Abstract
The invention provides an artificial kidney extracorporeal circuit assembly including an artificial kidney having detachably attached multifunctional subassembly means for automatically venting gas bubbles from liquid flowing therethrough, for continuously sensing the liquid pressure of and for filtering said liquid, together with blood tubes for connecting a patient's artery to the kidney and the subassembly outlet port to a patient's vein. The subassembly includes means associated with a hydrophobic gas bubble vent which prevent clogging, minimize blood clotting and insure against ambient gas entry through the vent.
