The description focuses on the physical process of reverse osmosis and standard safety features, with no mention of AI or ML technologies.
No.
Explanation: The device is a water treatment system specifically designed to pre-treat and purify water for use in making dialysate for hemodialysis. It does not directly interact with the patient's body for therapeutic purposes. Its function is to prepare the water that will then be used in another therapeutic process (hemodialysis).
No
Explanation: The device is a water treatment system designed to purify water for hemodialysis applications, not to diagnose a medical condition.
No
The device description clearly outlines a physical water treatment system with hardware components such as pumps, membranes, filters, and safety features like pressure switches and conductivity monitors. It is not solely software.
Based on the provided text, the AmeriWater MRO Portable Reverse Osmosis Systems are not IVD (In Vitro Diagnostic) devices.
Here's why:
- Intended Use: The intended use is to purify water for use in making dialysate for hemodialysis. This is a water treatment process, not a diagnostic test performed on biological samples.
- Device Description: The description details a physical process of reverse osmosis to remove impurities from water. It does not describe any components or functions related to analyzing biological specimens.
- Lack of IVD Characteristics: The text does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Providing diagnostic information about a patient's health
- Using reagents or assays
- Measuring biomarkers or other biological indicators
The device is a water purification system used in a clinical setting to prepare water for a medical procedure (hemodialysis), but it does not perform a diagnostic function itself.

Device Description
Osmosis is a natural process where two liquids of different concentration are separated by a semi-permeable membrane and the liquid moves from the lower concentration to the higher concentration in order to achieve chemical equilibrium. Reverse osmosis, the scientific concept used in the AmeriWater MRO Portable Reverse Osmosis System, is the opposite of osmosis. Liquid is forced from a region of higher solute concentration through a semi-permeable membrane to a region of lower solute concentration. This is achieved by applying a pressure in excess of the osmotic pressure. Osmotic pressure is the pressure which needs to be applied to a solution to prevent the inward flow of water across a semi-permeable membrane. The MRO system uses a submersible pump to apply the pressure required for reverse osmosis.
The semi-permeable membrane used in the MRO system is a thin film composite (TFC) membrane. A TFC membrane is essentially a molecular sieve constructed in the form two or more layered materials. The membranes are made out of polyamide, chosen for its permeability to water and relative impermeability to various dissolved impurities and unfilterable molecules.
The MRO Portable Reverse Osmosis System purifies tap water by applying pressure (greater than the osmotic pressure difference) to the feed water supply in order to reverse the water flow through the semi-permeable reverse osmosis membrane so that the water moves from a more concentrated solution to a less concentrated solution resulting in purified permeate flow. Basically, the tap water is supplied to the MRO pump where ist is pressurized and sent to the membrane splits the tap water into permeate, which has passed through the membrane, and the concentrate, which passes over the membrane and carries the contaminants to drain. The AmeriWater MRO Reverse Osmosis System produces water that meets ANSI/AAMI RD62 requirements for water used in hemodialysis applications. It provides quiet operation for bedside use and may be used for acute care cases, small dialysis wings in a hospital, or for home care. Materials that contact the product water include: ABS, Acrylic, Carbon, Nylon, PVC, Polyester, Polyethylene, Polypropylene, Stainless Steel, Tygon, EPDM, Viton, and Buna N.
Tap water enters the AmeriWater MRO Portable Reverse Osmosis System and passes through dual carbon block filters to remove chlorine, chloramines, and sediment which may damage the RO membranes. The dual chloramine removal carbon cartidges are a special blended carbon that salisfies AAMI and CMS requirements. Rated at 1 micron, the filters have a capacity of 8000 gallons with 3 PPM of chloramine at 9.5 pH. The submersible RO pump then pressurizes the feed water to pressures greater than the osmotic pressure. The pressurized feed water is sent through the RO membranes where contaminants are removed, and the feed water is split into permeate, or product water, and concentrate, or reject water. The purified permeate water passes through a Nephros Dsu filter capsule (K110285) to remove microbiological contaminants (down to 0.005 microns) and then is directed to the point of use. A portion of the reject water is returned to the RO pump to reduce waste, and the remainder is sent to drain. Optional antiscalant (K991519) may be included for use on un-softened water supplies to remove hardness minerals that may scale the membrane.
The AmeriWater MRO Portable Reverse Osmosis System includes safety features for the user and to protect palient safety. The safety features meet current and include product water conductivity monitor with audible alarm, a low -pressure cut-off switch to prevent damage to the RO pump in low pressure situations, and a divert to drain feature that prevents product water with conductivity above the alarm set point limit from being used for patient treatment. The MRO also includes a simple disinfection procedure using hydrogen peroxide/peroxyacetic acid (PAA).

Statement of Substantial Equivalence: The AmeriWater MRO Portable Reverse Osmosis System is substantially equivalent in intended use, function, and technology to the AmeriWater Systems) Aseptech Portable RO+ systems currently cleared for market under K924695, and the AmeriWater RO+ systems currently cleared for market under K991519. The new device is basically the same design as the predicate device with the exception of controller modifications to meet the requirements of UL 60601-1. In addition, new features have been added to meet current AAMI requirements. These include dual carbon block filters equivalent to carbon beds with 10-minute empty bed contact time. The carbon block filters replace the single carbon tank previously used in the MRO. A product water divert to drain feature has also been added. This feature diverts all water to drain if the permeate conductivity exceeds the alarm set point limit. The Nephros Dsu filter capsule (K110285) has also been added in order to help meet the new AAM requirements for microbiological contaminants. The basic flow path and scientific concepts for the device have not changed, nor has the intended use, electrical requirements, or environmental and incoming water specifications.
