A close look at a segment of tubing covered with biofilm. |

The same tubing, just a few seconds after exposure to Novaflux's patented two-phase flow. |

We merely initiate a two-phase turbulent flow through a narrow channel,
generating impressive shear stress resulting in a complete removal of
microorganisms, to the extent of high-level disinfection. It works pretty
well, so we patented it.

Ok, a few definitions might clear things up. A phase is a state of matter – solid, liquid, or gas. When we initiate a "two-phase flow" all we are doing is pumping a mixture of a liquid and a gas into the tube. Just like a bumpy or turbulent plane ride can be disruptive to an airline passenger, turbulence in our two-phase flow is particularly disruptive to the biofilm or other contaminant lining the internal channels of the passageway. Luckily for us, the bacteria don’t have seatbelts to keep them from flying out of their chairs! Adding to the misery of these microbes and dirt particles is the surfactant we place in the flow. A surfactant is a chemical that helps break up organic material stuck to a surface. Our use of a surfactant instead of a biocide is critical. A biocide directly kills bacteria. However, as one might expect, biocides are extremely toxic and often corrosive, creating a potential hazard to the patient, consumer, practitioner or any other person coming into contact with it. Corrosive biocides can also damage expensive medical equipment. Furthermore, they can interact with organic material in the tubing and create harmful by-products. Our proprietary surfactant formulation does not harm people or equipment. In addition, when combined with turbulent flow, it completely removes the slimy matrix that bacteria leave behind, something no biocide can do. We are not only disinfecting, but we are removing the biofilm, and the removal is key. The term shear stress is just a fancy name for the force that the turbulent flow exerts on the surface of the contaminant lining the tube. A lot of shear stress is beneficial for us, because a greater force breaks up the lining more effectively. Finally, when we achieve high-level disinfection, it means
we’ve removed all harmful microorganisms present. High-level disinfection
is an appropriate cleaning method for "semi-critical" medical devices.
A semi-critical medical device is one that come into contact with
intact skin or mucous membranes, such as an endoscope. The technology
itself can actually achieve sterilization, which as good as it gets
as far as cleaning is concerned, but on a practical level, other sources
of contamination from outside the tubing prevent a sterile environment
from being maintained. |
