Answer to Question 2
1 . The three basic types of dialyzers are coil dialyzers, plate dialyzers, and hollow fiber dialyzers. In a coil dialyzer, the blood flows through a tube made of synthetic, semipermeable membrane material. The tube is wrapped around a mesh screen to form a coil, and the dialysate flows around the coil. 2 . In a plate dialyzer, blood flows within a synthetic, semipermeable membrane between two plates, and the dialysate flows in the opposite direction outside the membrane. 3 . A hollow fiber dialyzer consists of a bundle of hollow synthetic fibers through which the blood passes. The dialysate circulates around the outside of the fibers in the opposite direction.
