The Kiil dialyzer was constructed using which materials?

The Kiil dialyzer is designed for hemodialysis and is constructed using specific materials that provide effective filtration and biocompatibility. The correct choice includes membrane sheets and polypropylene plastic, which are essential for creating a semipermeable barrier that allows for the efficient exchange of solutes and fluids during the dialysis process.

Membrane sheets provide the functionality needed for the dialysis, as they are responsible for the removal of toxins and wastes from the blood while retaining essential cellular components and proteins. Polypropylene plastic is often used because it is chemically stable, relatively inexpensive, and has a low density, making it suitable for medical applications, particularly for producing disposable devices in a sterile manner.

This combination of materials ensures that the Kiil dialyzer can perform its intended function effectively while minimizing the risk of adverse reactions in patients undergoing dialysis. In contrast, glass, rubber, metal, ceramic, and wood do not offer the necessary properties required for constructing a functional and safe dialyzer and would likely compromise the effectiveness and safety of the dialysis treatment.
