Current evidence suggests that the majority of SSI result from bacteria alighting directly onto the surgical wound from the air. Based on our previous studies and on the preclinical results reported here, lamps emitting far-UVC light in the 200–222 nm range could potentially be used for continuous low-fluence/low-rate exposures during the course of a surgical procedure to inactivate bacteria before they penetrate into the interior of the wound. At bactericidal fluences, far-UVC light cannot traverse tissues with a stratum corneum such as skin and lens of the eyes.

The use of this light would therefore not require additional protective clothing for patients or medical staff and could become a standard in hospital environments to reduce SSI rates, particularly those due to drug-resistant pathogens. In addition, targeting bacteria as they alight onto the wound would prevent the formation of bacterial clusters or biofilms, which are difficult to eradicate and impede wound healing.

Other potential applications of far-UVC light is sterilization of any environment with a high likelihood of airborne-based pathogen transmission, including tuberculosis, small pox, severe acute respiratory syndrome (SARS) and pandemic influenza, which collectively affects one billion people annually. Although upper-room UV-irradiation systems based on conventional broad-spectrum UV lamps have long been considered for room sterilization, they cannot be widely used due to safety concerns relating to skin cancer and cataract risks.

Collectively, our studies suggest that far-UVC light (200–225 nm), unlike conventional UV germicidal lamps, has considerable promise to be a safe and inexpensive modality for SSI reduction, while being cytotoxic to both drug-resistant and drug-sensitive microbes.

My Lumens Artemis Far UVC Disinfection Devices equipped with Care222 module(filtered far uvc 222nm technology) developed by Ushio, Japan.

Care222 is a new disinfecting light source that, even though not harmful to the skin or eyes of humans or animals, deactivates bacteria and viruses in the same manner as conventional ultraviolet sanitizers.

Does not cause sunburn, skin cancer or cataracts

Ultraviolet rays with a wavelength of 222 nm are absorbed by the cornea of ​​the stratum corneum of dead cells, so they do not cause damage such as sunburn, skin cancer, and cataracts.

Virus suppression / sterilization

Ultraviolet rays with a wavelength of 222 nm destroy the DNA / RNA structure of viruses and cells, and suppress and sterilize them.

A key advantage of the UV-based approach is that UV light is likely to be effective against all airborne microorganisms, in marked contrast to vaccination methods. For example, while the inactivation efficiency of UV light will almost certainly vary as different strains of influenza virus emerge, they are unlikely to be significant. Similarly, as multidrug-resistant variants of bacteria emerge, their UV inactivation capacity is unlikely to vary greatly.

The use of Care222 in public places is a safe and effective way to limit the spread and transmission of air-mediated microbial diseases, such as schools, hospitals, stadiums, sports grounds and offices, and this approach may help to limit seasonal infections, the spread of tuberculosis and major epidemics.
