Clinical Studies of the TRU-D Device
High-Dose Ultraviolet C Light Inactivates Spores of Bacillus subtilis var. niger and Bacillus anthracis Sterne on Non-reflective surfaces
Summary
Ultraviolet light (UV-C) is frequently used in clinical settings to reduce the risk of nosocomial infections. Surface areas or air-flow in high risk areas are treated with UV-C to decrease infectious microorganism populations. Other means of decontamination are sometimes employed. Gaseous disinfection with ethylene oxide, chlorine dioxide, or formaldehyde is costly and is corrosive to electronics, hazardous to workers and the environment, and requires prolonged evacuation of the treatment area. Liquid disinfectants must be manually applied and removed, refreshed continuously to avoid cross-contamination, may encourage chemical-resistant strains, and may damage exposed materials such as electrical devices.

Alterations of bacteria colony counts in the inanimate environment of an Intenstive care unit by use of the TRU-D device.
Summary
This protocol substantiates the claim that the TRU-D device is able to deliver doses of UV-C in a predictable manner to areas of relative shadow in patient care areas to achieve significant reduction of bacteria colony counts in cultures taken from the inanimate environment of an intensive care room.

Inactivation of Staphylococcus Aureus bacteria by UV-C irradiation produced by the TRU-D Device.
Summary
This protocol substantiates the claim that the TRU-D is able to deliver predictable doses of UVC to areas of relative shadow in patient care areas sufficient to achieve at three log or greater reduction of staphylococcus aureus bacteria.
