Dialysis is a medical treatment that washes blood, typically because of kidney failure. Waste products and excess fluids are removed. There are two types, namely Hemodialysis and Peritoneal Dialysis. In Hemodialysis a dialysis machine filters the blood outside of the body. Peritoneal Dialysis utilizes a patient’s abdominal body cavity (peritoneal membrane). Blood is cleaned within the human body.
Key Pump Functions and Requirements
Several functions can be handled by pumps within a dialysis machine. This includes degassing of the dialysate, system checks, pressure level control or operating pneumatic valves and drawers. In all instances, the pumps must work reliably and to the point. A low sound level and minimum vibration is key for patient comfort. A long lifetime and service free operation is an added plus for this critical life support system.
The Thomas Solution
Thomas gas diaphragm pumps are leak tight by design and keep the dialysate and blood contamination free. Piston pump technology generates higher vacuum or pressure levels and is ideally suited for pneumatic functions. Several DC and BLDC motor options allow for precise working point setting and pump controllability. All technologies are designed for reliability and service free operation.
