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.
