The dialyzer functions as the filtration unit in the hemodialysis circuit. It consists of thousands of semipermeable hollow fibers that facilitate the exchange of solutes and fluids between the patient’s blood and the dialysate solution. The dialysate solution, formulated with specific concentrations of electrolytes and other substances, creates a concentration gradient that allows for the removal of waste products from the blood.
Components:
Key components of the dialyzer include:
• Hollow Fibers: Semipermeable tubes made of synthetic or cellulose-based materials that allow selective permeability.
• Housing: The outer casing that encases the hollow fibers, typically made of plastic.
• Headers: Located at each end of the dialyzer, these distribute blood and dialysate into the hollow fibers.
