FX Dialyzers — Blue makes a difference

"Small details can make a big difference in medical outcomes."

Dialyzers overview

Why FX Dialyzers make a difference

FX Dialyzers have been used in more than 500 million treatments worldwide. As the world’s leading provider of dialysis products, Fresenius Medical Care aims to make a difference — for patients and healthcare professionals.

Continuous innovation combined with our commitment to the highest level of quality standards, ensure that our FX Dialyzers portfolio is built to address the individual needs of patients.

Why FX Dialyzers make a difference

FX portfolio

All FX Dialyzers have the capacity to remove a broad range of uremic toxins, effectively retain endotoxins, and provide intrinsic biocompatibility.1

FX CorDiax

FX CorDiax

Designed to dialyze, built for cardioprotection

The FX CorDiax dialyzers feature the advanced Helixone® plus membrane, enabling the enhanced removal of larger uremic toxins, such as β2-microglobulin and myoglobin.2,3.At the same time, it restricts the loss of albumin, which is of clinical concern and a safety issue in hemodialysis.4

FX classix

FX classix

High-flux dialyzers for improved patient outcomes

The FX classix dialyzers, featuring the original Helixone® membrane, target at an efficient removal of a broad range of uraemic toxins with high endotoxin retention characteristics.5,6

FX classix dialyzers provide high-flux hemodialysis therapy to improve clinical outcomes in patients in comparison to low-flux hemodialysis.7

FX paed

FX paed

High-flux dialyzer for paediatric treatments

The FX paed dialyzer enables high-flux hemodialysis therapy ideally suited for the special needs of pediatric patients. It features the original Helixone® membrane, which targets at an efficient removal of a broad range of uremic toxins, with minimum albumin losses and high endotoxin-retaining characteristics.8

FX low-flux

FX low-flux

Advanced design for low-flux dialysis

The removal of uremic toxins and excessive water is the fundamental goal of the hemodialysis treatment. Due to the beneficial properties of the Helixone® low-flux membrane combined with its advanced product design, the FX low-flux dialyzers offer adequate performance.9

A smooth treatment is the difference that allows us to focus more on the patient.

FX properties that make a difference

Several state-of-the-art technologies have been combined to create the distinctive functional properties of the FX Dialyzers. Together they make a difference in terms of beneficial patient outcomes, smooth handling and cost savings potential.

FX properties that make a difference
  • 1. Lateral blood inlet port
  • 2. System compatibility and more
  • 3. Sophisticated fiber architecture
  • 4. Optimized header design
  • 5. INLINE steam sterilization
  • 6. Sustainable product design

Smooth handling

The blue header with its laterally placed blood inlet port is designed to reduce the risk of kinked bloodlines, aiming at smooth handling and allowing healthcare professionals to focus on what really matters — the best care for patients.

Smooth handling

Simplified workflows

The FX Dialyzers are developed for system compatibility, perfectly fitting into automatic priming procedures with low rinsing volumes and short preparation times. In addition, there is no need to turn any FX Dialyzer during the priming procedure. Moreover, the FX Dialyzers have a removable label that can easily be attached to patient records, allowing for quick documentation.

Simplified workflows, user-friendly handling and short preparation time support the nursing staff’s daily work — freeing up resources to focus more on patients.

Improved clearances

Fresenius Medical Care’s Nano Controlled Spinning (NCS™) technology creates fibers with a highly defined membrane architecture. Precise nanoscale modulation of pore size, structure and distribution favors minimal resistance to solute transfer across the membrane and contributes to improved clearances compared to macro-design membranes.10,11

Additionally, the microwave fiber structure enables the homogenous distribution of dialysis fluid, supported by the inner housing’s pinnacle design of the FX Dialyzers. It prevents the channelling of the dialysis fluid and ensures that each fiber within the bundle is perfectly surrounded by the dialysis fluid.11,12,13

Improved clearances

Enhanced performance

The optimized header design of the FX Dialyzers ensures a homogenous blood flow path. Its geometry allows a spiral distribution of blood in the dialyzer header, preventing low velocity stagnation zones and resulting in an enhanced performance.11

Enhanced performance

Setting the standard

Each FX Dialyzer is individually sterilized by the unique INLINE steam sterilization method. Both the blood and the dialysate compartments of the dialyzer are rinsed continuously with steam at a minimum temperature of 121° C, followed by sterile water and sterile air.

Rinsing with hot steam assures a gentle sterilization — without the need for chemicals or irradiation, which may lead to increased cytotoxic14 and carcinogenic residuals.15,16

Optimal use of resources

The INLINE steam sterilization process allows for the efficient use of resources during preparation as well as a reduction of costs, since only 500 mL rinsing volume is required. The process

  • includes a 100% fiber integrity test, aimed at minimizing the risk of blood leakages due to fiber ruptures
  • ensures that all FX Dialyzers are already pre-rinsed and ready to use upon arrival, resulting in short rinsing time and low rinsing volumes.

Best choice for high biocompatibility

Cytotoxicity is minimal after steam sterilization, whereas it increases with gamma irradiation.14 Studies have shown that with steam sterilized dialyzer membranes, less oxidative stress is induced to the patient’s blood compared to gamma sterilization.17,18,19

Performance characteristics remain intact

Changes of the material properties can be observed after sterilization with gamma irradiation, while the material remains intact in this respect when using steam sterilization.20

Increased losses of albumin during dialysis sessions have been observed with gamma sterilized dialyzers which were stored for a longer time.14,21

Setting the standard

Adding value across the entire life cycle

Fresenius Medical Care has implemented an approach based on the Life Cycle Assessment (LCA) methodology, which follows the structure and requirements of EN ISO 14040/44: 2006:

  • Comprehensive assessment of a product’s environmental impact across its full life cycle, from materials supply to manufacturing, distribution, use and final disposal
  • Identification of improvement opportunities through environmentally sound processes, materials and design choices.

Lightweight material is essential for environmental sustainability

The advanced housing material of any FX Dialyzer is made of environmentally friendly and lightweight polypropylene. Due to the advanced material, FX Dialyzers up to 50% lighter (before treatment) than dialyzers made of polycarbonate22 
This may result in improved end-of-life management by producing less waste23 and contributing to cost savings.

Improved eco-performance

Across 15 environmental impact categories24, the overall eco-performance of an FX Dialyzer (FX classix 80) is notably better — on average by 42 % — compared to a reference dialyzer made from polycarbonate (HF 80S).25

The difference is feeling confident throughout the entire treatment.

FX blue art project

Dialyzers are life-saving pieces of medical and technological art. The advanced design of the FX Dialyzers adds a dimension that reflects the thought, care and quality that went into its construction. As the most prominent visible characteristic, the color blue of the FX Dialyzer caps became the inspiration point for our unique blue art project. We asked artists to interpret the benefits of the FX Dialyzers in their own way — be it figurative or abstract, poetic or surreal, two- or three-dimensional — with stunning results.

Each artist granted another level of meaning, a unique interpretation or a new perspective to apply to the distinctive functional properties of the FX Dialyzers. Warm and sensitive, intellectual and meaningful approaches came to life.
