Diafilters
For continuous renal replacement therapy
MEDIVATORS offers the most convenient and efficient system available for your patient’s hemofiltration needs. The Diafilter Hemoconcentrator/Hemofilter fibers are crafted from glycerin-free polysulfone membranes, a unique material that has demonstrated exceptional biocompatibility. The glycerin-free membrane offers the convenience of a no-rinse procedure. Set-up of the Minntech D-20NR, D-30NR and D-50NR Hemoconcentrator/Hemofilter involves only priming the unit to remove air.
Clinical Benefits
- Low priming volume helps maintain low volume in the extracorporeal circuit
- Polysulfone membrane offers excellent biocompatibility
- Meets the biocompatibility requirements of ISO 10993-4 selection of tests, for interactions with blood
- No rinse fiber for convenient set up
- Excellent ultrafiltration rates for reliable fluid removal
- Low pressure drop ensures continuous operation
