The Allient dialysis system.

The Allient is a dialysis system that combines various technologies to allow dialysis to be performed at sites outside of dialysis units (intensive care unit [ICU] or home) with ease and safety. A sorbent column regenerates dialysate, removing toxins and providing ultrapure dialysate from only 6 liters of tap water. The use of the sorbent column eliminates the need for costly and complex water purification systems. The Pulsar Blood Movement System provides blood flow at constant negative or positive pressure through single-lumen or dual-lumen accesses, maximizing blood flow rate while eliminating bothersome pressure alarms. Ultrasonic flow monitors control the operation of the pump and ensure adequate blood flow during each dialysis treatment. A completely disposable blood tubing and dialysate circuit eliminates the need for sterilization of the machine. The Allient should make dialysis in the ICU or home setting much more practical, reducing training requirements and increasing safety.
