Abstract

The control of nosocomial infections has never been more critical than in the current pandemic caused by Sars-Cov2. In the most sensitive areas of a hospital, infection control is a mandatory protocol. One of MLA Suprimentos Médicos goals is the development of products with the capacity to help the control of hospital infections. This innovation is a heat and moisture exchange filter (HMEF) with biocidal activity for mechanical ventilation medical equipment. The antimicrobial and antiviral activity was conferred based on the application of green nanotechnology in the development of a specific formulation based on silver nanoparticles (AgNPs). The heat and moisture exchange filter can be used in intubated patients under artificial ventilation in anesthesiology and intensive care and allows a robust replacement, a fundamental utility for protection against nosocomial cross-contamination infections caused by microorganisms such as bacteria, fungi, yeasts and virus.
