Abstract
Methods and apparatuses for inactivating RNA and DNA within viruses situated on medical instruments. Through the use of photochemicals and photoactivation by monochromatic light, medical instruments can be rendered safer. A solution of methylene blue having a concentration of 0.01-0.02% by means of interaction with light in the emission spectrum of monochromatic emitters having wavelengths ranging between 582 and 592 nm or between 658 and 662 nm and an overall light output of at least 280 lumens (lm), wherein the instruments are kept in said solution for about 90 minutes.
Claims7
A method for inactivating RNA and DNA contained in viruses on medical instruments, comprising:
- preparing a methylene blue aqueous solution having a concentration from about 0.01% to about 0.02%,
- immersing at least one medical instrument into a container containing said methylene blue aqueous solution, said container being within a housing;
- sealing said container within said housing;
- and
- irradiating, by a monochromatic light source within said housing and above said container, said methylene blue aqueous solution in said container with monochromatic radiation for at least about 90 minutes,
- wherein said monochromatic light source emits a total light output of said monochromatic radiation on said methylene blue aqueous solution greater than about 280 lumens,
- whereby RNA and DNA of viruses on said at least one medical instrument are inactivated.
