Biologically Safe Water Filters

RO Machine fitted with Dual Stage Ultrafilter

This shows a portable RO machine with the DSU between the RO machine and the dialysis machine.  This could also be done with a DI water system.  Having a .005 micron filter just prior to your dialysis machine will control any endotoxin issues.  The ultrapure water will provide the patient with a higher quality treatment and will help lower infection rates.

Ultrapure water will help prevent healthcare associated infections (HAI’s).  This will reduce hospital costs.  Insurance companies and Medicare will discontinue reimbursing for HAI’s, thus the financial burden is now on the hospitals.  Reduction in HAI’s will reduce the patient’s length of stay in the hospital.

Ultrapure dialysate, in dialysis, will reduce inflammatory endotoxins and, therefore, improve hematocrits.  An improvement in hematocrits will allow a reduction in EPO doseage.  This is a major financial benefit for facilities who have patients with a bundled or capitated reimbursement rate.  The dialysis patient receives an overall improved treatment.

Results of an efficacy study released 11/5/08

Principal Investigators:

Yusen E. Lin, PhD, MBA, National Kaohsiung Normal University, Taiwan

Janet E. Stout, PhD, University of Pittsburgh

Study: This study compares water from a faucet fitted with a Nephros DSU, to water from a control faucet without any filter.  Total water volume of 30,240 liters (3.6 L/min) was used.  This represents 7.5 months of filter use at 4,000 liters/month.

The filter was challenged with the following test organisims: Legionella, Pseudomonas, Stenotrophomonas, Acinetobacter, Klebsiella, Mycobacterium

Results: No bacterium was recovered from the faucet water filtered by Nephros DSU.  The control faucet, with no filter, had bacteria colonization showing various levels of the test organisms.

The DSU filter should be able to help dialysis units in a number of areas.

• Post RO/DI to polish the water (good for acute units)
• >After the bicarb mixer on the bicarb central feed line (controls bacteria)
• One on the RO line and one on the bicarb line, just as they enter the dialysis machine.  This will help clinics get to “Ultrapure” dialysate.  Ultrapure dialysate can help lower infection rates and provide a better dialysis treatment.
• Use with reuse machines (Renatrons) to provide ultrapure water when cleaning the dialyzer.

A 510k is expected by July 2009.
