Desenvolvimento e avaliação da eficácia de uma tecnologia vestível de desinfecção por ozônio aplicado a vestimentas contaminadas

Abstract

The sudden shift brought about by COVID-19 in mid-2020 led to an expansion of traditional biosafety protocols, while simultaneously generating a high volume of research and development into methods to combat the transmission of the SARS-CoV- 2 virus. In this context, this study presents the creation of a biological protection system in the form of wearable equipment, designed for disinfection using gaseous ozone contained within a wearable, spray-infused technology. Ozone (O3) stands out for its strong oxidizing capacity and its natural decomposition back into oxygen (O2), and is also characterized by its effectiveness in eradicating 99.9% of bacteria, fungi, viruses, and protozoa. The methodology employed is characterized by applied research of an experimental nature, involving the development of a wearable technology made of polymeric material, equipped with a mechanical fitting for the injection of gaseous ozone, capable of reducing the potency and even eliminating the transmitting agent, as well as other viruses and bacteria. The efficiency of this equipment was tested through experimental protocols that demonstrated significant reductions in microbial concentration, exceeding 3 log10, confirming the effectiveness of the developed and proposed biological protection system. Therefore, it is concluded that the creation of this system for biological protection using confined ozone, constructed in the form of a spray capsule, demonstrates technical feasibility, operational reliability, and potential application in certain scenarios.
