A hemodialysis machine, known in Estonian as a hemodialüüsiseade, is a medical device used in hemodialysis treatment. Hemodialysis is a process that removes waste products and excess fluid from the blood when the kidneys are no longer functioning properly. The hemodialysis machine plays a crucial role in this life-sustaining procedure.

The core function of a hemodialysis machine is to pump the patient's blood through an artificial kidney, called a dialyzer. Inside the dialyzer, blood flows on one side of a semipermeable membrane, while a dialysis fluid, or dialysate, flows on the other side. This membrane allows waste products and excess water to move from the blood into the dialysate, while essential substances like red blood cells and proteins remain in the blood.

Modern hemodialysis machines are complex and incorporate several key components. These include pumps to control blood flow rate, pressure sensors to monitor and maintain safe pressures within the circuit, and a dialysate delivery system that mixes and heats the dialysate to the correct temperature and composition. Safety features are paramount, with alarms designed to alert staff to any potential issues such as air in the bloodline, clotting, or significant changes in blood pressure. The machine also facilitates the return of the cleansed blood to the patient's body. Hemodialysis machines are vital for patients with end-stage renal disease, enabling them to manage their condition and maintain a level of health.
