Effectiveness of V Shield

On-site Medical Services independently evaluates every service or product we offer. In furtherance of this mission, we have compiled a comprehensive explanation of V Shield; a safe and effective product we stand behind. 

 

The V Shield Sterilization Multipurpose Clip is a wearable device that emits chlorine dioxide vapor around the wearer.  It provides a 1-meter range “bubble” of chlorine dioxide to protect the wearer from viruses, bacteria, fungus, and other microbes.  Each clip is effective at sustaining the release of chlorine dioxide for 30 days. The V Shield Clip is registered with the FDA as a medical device and is approved by the EPA, EU, Korea Ministry of Health, and the World Health Organization. OSHA regulates chlorine dioxide with the limit being 0.1 ppm and the V-Shield Clip emits at 0.07 ppm, meaning it is safe for use.   Chlorine Dioxide is a strong oxidant that can inhibit or destroy microbes.  Chlorine dioxide gas is highly diffusible and permeable meaning it can access small spaces that are hard to disinfect. It has been shown that at low concentrations chlorine dioxide gas has the ability to inactivate gram-positive and gram-negative bacteria. Chlorine dioxide at low concentrations has shown to have no toxic effects in humans or animals.

Influenza, a respiratory virus, is among the most frequent infections of the upper and lower respiratory tracts in humans and spreads in the air as aerosols.  In a study examining the effects of low-concentration chlorine dioxide gas against the influenza A virus, mice were exposed to the virus and chlorine dioxide. Mice have exposed to chlorine dioxide gas and aerosols of the influenza A virus simultaneously.  This resulted in the protection of the mice from influenza by decreasing the number of infectious viruses in the mice’s lungs.  The mice also suffered no damage to their lungs from the chlorine dioxide gas.  

When chlorine dioxide is dispersed through the air, it can be distributed to areas beyond the reach of liquid sanitizers. It has been shown that gaseous chlorine dioxide is a rapid and effective sterilizing agent active against bacteria, yeasts, and molds.  A study examined the effect of chlorine dioxide gas at different concentrations on a human norovirus surrogate, murine norovirus.  Murine norovirus is used as it is a proper surrogate for human norovirus.  When the virus was exposed to 0.1mg/L of gaseous chlorine dioxide for 30 seconds there was a significant decrease in the number of intact virus particles. At higher concentrations, no intact virus particles were found.  This demonstrates that the gaseous chlorine dioxide damaged the viral capsid and disrupted virion structure.  Further investigation into the mechanism of viral inactivation by chlorine dioxide found that viral capsid protein was reduced.  Viral capsid protein significantly diminished when exposed to 0.1mg/L of gaseous chlorine dioxide for 30 seconds, and at higher concentrations and treatment time, viral capsid protein was undetectable.  Exposure to chlorine dioxide was found to degrade viral capsid protein.  It was also found that chlorine dioxide degrades viral genomic RNA.  When the virus was exposed to 0.1mg/L Chlorine Dioxide for 30 seconds, the virus gene (VP1) decreased and at high concentrations and treatment time, the gene was undetectable.  The study concludes that gaseous chlorine dioxide can be effective at inactivating a human norovirus surrogate.

 

On-site Medical Services stands behind V Shield's innovative technology. Furthermore, we endorse the use of V Sheild whenever possible. V Shield along with onsite covid testing and symptom tracking applications, Wellbility, is essential to achieving infection mitigation.
