Definition
A dialysis machine is a medical device used to filter waste and excess fluid from the blood when the kidneys are not functioning properly. It essentially acts as an artificial kidney, removing toxins that would otherwise build up and cause harm. The process involves circulating the patient's blood through the machine, cleaning it, and then returning it to the body. Think of it like a sophisticated water purification system, but for your blood. Dialysis is a life-sustaining treatment for people with kidney failure, offering a way to maintain a healthy balance of fluids and electrolytes. It's a temporary fix, however, as it replaces the function of the kidneys, not cures the disease.
