Patent ID: 11351281

Abstract:
The present invention discloses devices and methods for sterilizing protective facial masks and medical garments using microwave energy. Devices include: a fabric sterilization unit for serving as a housing; a water basin disposed inside the sterilization unit, the water basin configured for generating steam in the water basin when exposed to the microwave energy; a nozzle array plate disposed inside the sterilization unit above the water basin, the nozzle array plate configured for increasing the steam pressure by restricting steam escape; an array of steam-jet nozzles with angled upper sections configured for directing a flow of high-pressure, high-temperature steam jets exiting from the nozzles toward at least one fabric material; and material holders for individually positioning and supporting the material such that the steam jets impinge on the material for: sterilizing the material from microbial transmission and/or reproduction; and enabling reusability of the material as suitable Personal Protective Equipment (PPE).
