Faq's Renaclean⁺ Dialyzer Reprocessing System

Ans. Steps involved in reprocessing dialyzer on Renaclean⁺ Dialyzer Reprocessing Machine are as follows:

1. Step I - Rinses the dialyzer with about 20 P.S.I. water pressure thereby removing the blood, proteins, etc. from the dialyzer completely
2. Step II - It cleans the dialyzer using 2.5% Renaclean Cold Sterilant and by using reverse ultra filtration technique
3. Step III - It checks the bundle volume and the membrane integrity
4. Step IV - It fills dialyzer with 3.5% Renaclean Cold Sterilant for sterilization

Ans. Renaclean⁺ Dialyzer Reprocessing Machine performs 2 types of tests - Bundle Volume Test and Pressure Test. It rejects the dialyzer if the bundle volume is less than 80% as per AAMI standards. It fails the pressure test if the pressure drop is more than 8% per 30 sec. for low flux dialyzers, 10% per 30 sec. for influx dialyzers and 12% per 30 sec. for high flux dialyzers.

Ans. Reuses depend on a lot of factors. But we have found that reuses can be doubled as compared to manual reuse. For e.g. if you get 6 reuses manually, you are likely to get 10-12 reuses using Renaclean⁺ Dialyzer Reprocessing System.

Ans. Approx. 7 ltrs.

Ans. Renaclean⁺ Dialyzer Reprocessing System consumes 140W per hour and assuming that machine is running for 14-15 hours, machine consumes about 2 units per day.

Ans. It takes only 26.5 ml. for rinsing, cleaning and sterilizing one dialyzer.

Ans. As it needs only 26.5ml. for reprocessing one dialyzer, one 5 litre canister costing Rs.2,475/- can reprocess about 188 dialyzers thereby costing about Rs.13/- per dialyzer.

Ans. It is recommended that at the end of every day, machine should be disinfected and bleach disinfection should be carried out once in two months only.

Ans. Firstly to ensure the quality of reprocessed dialyzers and validation. Manually you cannot guarantee the quality of reprocessed dialyzers as it would tend to vary from person to person. Further there is no validation since there is no way a technician can check the bundle volume and the membrane integrity of each and every dialyzer.

Secondly, you can reduce the cost of dialyzer per dialysis as you can double the reuses as compared to the no. of reuses that you get with manual reprocessing.

Given below is the calculation of the saving:

Ans. Renaclean⁺ Dialyzer Reprocessing System is CE certified, double station and designed by Dr. Prakash Keshaviah, who is a well known authority on dialysis. Since the machine is manufactured in India the spare parts are freely available at all times and at very economical prices. As the price of double station Renaclean⁺ Dialyzer Reprocessing Machine is almost 2/3rd the effective price per station works out to 1/3rd of the price of the imported reprocessing machines. Apart from this, there are lot of features which are not available in imported reprocessing machines. Please refer to the comparison sheet available in this website under the heading downloads.

Ans. No, the System has been carefully designed by the renowned Dialysis Expert, Dr. Prakash Keshaviah, to prevent cross-contamination. It is possible due to the following design principles that have been invoked in the hydraulic system design.

1. Valves used in the system are one-way valves that do not allow reverse flow.
2. Valve closure is achieved with a high spring force sealing a polymeric membrane against a flush machined surface providing complete closure against pressures up to 20 P.S.I.
3. All flows naturally take place from areas of high pressure to areas of low pressure.
4. During the reverse filtration or even when the blood compartment is being flushed, the manifold design and valve openings are such that the flow goes directly to the drain line, the area of lowest pressure in the system.
5. During this flow towards the drain, 2 closed valves prevents any flushed fluid from one dialyzer being able to contaminate the other dialyzer.
6. Because of the high flow rates used during the cleaning process, convective transport greatly exceeds any potential for diffusive transport of contaminants. Further, diffusive distances are too long, and cleaning times too short, for diffusive transport.

Ans. The life of Renaclean⁺ Dialyzer Reprocessing System is around 7 years or 70,000 cycles.
