PureFlow SL Water and Dialysate Preparation System

NxStage PureFlow SL offers water purification and dialysate production in one integrated unit specifically designed for use at home or in-centre.

The NxStage System One with PureFlow SL is a preconfigured haemodialysis 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-centre and home use.*

PureFlow minimises the delivery, storage, inventory management, and disposal challenges associated with prepackaged bagged dialysate. Each bag of concentrate replaces between eight and twelve 5-litre bags of prepackaged dialysate, depending on your patient’s prescription.

Benefits

Patient preferred and recommended1†

  • Compact size
    The PureFlow chassis and control unit weigh approximately 27 and 16 kg, respectively, and are combined 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, undersink, 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 percent 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 60 litre 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, 5 litre bags, with a variety of fluid configurations.

* Source water must meet purity requirements listed in the PureFlow SL User Guide.

† Patient surveys were sent to all 934 active PureFlow SL users on record at the time, of which 288 (or 31%) responded.
