1. A medical device that removes waste products and excess water from the blood in patients with kidney failure, typically by filtering blood through a semipermeable membrane.
Usage: Also called a dialysis machine.; Medical/healthcare context.
2. A container or apparatus used in laboratory dialysis to separate molecules of different sizes through a semipermeable membrane.
Usage: Scientific/laboratory context.

Examples

• The patient spent four hours connected to the dialyzer three times a week.
• Modern dialyzers are more efficient at removing toxins from the blood.
• The dialyzer uses a semipermeable membrane to filter waste products.
• Technicians regularly maintain the dialyzer to ensure it functions properly.
• In the lab, we used a dialyzer to separate proteins from smaller molecules.
• The dialyzer is an essential piece of equipment for patients with end-stage renal disease.
