An antimicrobial light device with clinical utility in the United States and abroad

Healthcare-associated infections, specifically those acquired as the result of an invasive medical or surgical procedure, are common in first-world nations as well as the developing world, and are associated with high morbidity, mortality, and billions of dollars (US) in cost. Blue light centered at 405 nm has been identified as a potential adjunct antimicrobial tool to treat and prevent infection. An antimicrobial light device has been developed to disinfect skin and wound surfaces by adjusting light intensity and treatment times to provide precise irradiance and fluence values which match effective published values from the literature.
