[0078] Surface disinfection

[0079] The purpose of the test reported here is to show that the simultaneous application of ultraviolet light wave energy and ultrasonic sound wave energy of the present invention is effective for selected microbial groups, including viruses, bacteria, fungi, molds and other surface or airborne biological contaminants on solid surfaces and in airflow. , The disinfection efficiency.

[0080] (a) Use ultraviolet light wave energy and ultrasonic sound wave energy to estimate surface disinfection

[0081] Testing was conducted over a period of 24 months to provide various working conditions and environments: allowing monitoring of the effectiveness of any increase or decrease in the application of simultaneous application of ultraviolet light wave energy and ultrasonic sound wave energy based on the present invention. Choose conditions that can provide a wide range of temperature, humidity, air disturbance, natural and artificial light, and other unfavor...

Abstract

A method and apparatus for sterilizing organic or inorganic matter through simultaneous exposure to ultrasonic wave energy (12) and ultraviolet light energy (14) in a non-aqueous environment such as air. The method is suitable for use in a chamber (60, 84) or in a mass production assembly line setting. Purification of air is similarly accomplished using simultaneous exposure to ultraviolet light and ultrasonic energy waves.

Description

Technical field [0001] The present invention generally relates to disinfection methods, and more specifically, to a method and equipment for disinfecting organic and inorganic substances in an anhydrous environment and for disinfecting air using a combination of ultraviolet light wave energy and ultrasonic energy. Background technique [0002] Efficient removal of viable pathogenic microorganisms is essential for those who are in frequent contact with potentially infectious microorganisms. Medical staff, dentists, and oral health workers are frequently exposed to body fluids that may contain infectious microorganisms such as viruses and bacteria. Instruments (including human hands) must be disinfected efficiently to prevent the spread of potentially infectious microorganisms between patients and to the staff themselves. Microbiological researchers often deal with potentially infectious microorganisms as a common part of their duties and require efficient and frequent disinfection...
