PureFlow™ SL Water and Dialysate Preparation System
Click to enlarge images.
The NxStage System One with PureFlow SL is a preconfigured FDA-cleared hemodialysis system, designed, tested, and validated to yield AAMI/ANSI/ ISO quality (which includes standards for chemical and chlorine/chloramine testing) water and dialysate for in-center and home use.*
PureFlow minimizes the delivery, storage, inventory management, and disposal challenges associated with prepackaged bagged dialysate. Each bag of concentrate replaces between eight and twelve 5-liter bags of prepackaged dialysate, depending on your patient’s prescription.
Patient preferred and recommended1†
Compact size
The PureFlow chassis and control unit weigh approximately 27 and 16 kg respectively and is the same size as a standard end table. In addition, the batch preparation dialysate system of PureFlow eliminates the need for bagged dialysate storage and handling.
No permanent plumbing or electrical modifications needed
Simple faucet, under-sink and washer hook-up adapters are all that are needed to install PureFlow.
Less water waste
Deionization (DI) technology with dual bed DI resin redundancies uses 100% of source water.
Lower source water flow rate
Accommodates more home water sources than alternative water purification systems, allowing 3.2 gallons/hour vs. 48-120 gallons/hour.
Continuous water purity monitoring
Even if source water integrity changes over time, the PureFlow SL output water quality does not change.
Convenient dialysate batch process
The dialysate SAK reduces bag handling, storage, and disposal. It is pre-filled with concentrate to make up to 60L of dialysate or up to 3 treatments per batch. It is designed for patient ease of use with no user intervention required during batch making.
Premixed Bagged Dialysate is also available for home patients in sterile, 5L bags, with a variety of fluid configurations.
The PureFlow SL System prepares batches of dialysate in the following formulations and volumes:
