US-based Bon Secours Virginia Health System has deployed germ-eliminating UV disinfection robots, Tru-D SmartUVC, in a bid to protect patients from serious healthcare associated infections.

Tru-D SmartUVC is short for Total Room Ultraviolet Disinfection, which is claimed to be the only portable UV disinfection system that exactly measures reflected UVC emissions with Sensor360. The robots automatically calculate the pathogen-lethal UV dose required for properly disinfecting healthcare environments.

Tru-D president Chuck Dunn said: "Tru-D can achieve 99.99% disinfection of all viruses and bacteria. It takes the guesswork out of previous protocols and ensures confidence in clinicians and patients alike."

Six of the 5ft robots are in use at different Bon Secours hospitals in Richmond, including three at St Mary’s Hospital, one each at St Francis Medical Centre, Memorial Regional Medical Centre and Mary Immaculate Hospital in Newport News, Virginia.

"Tru-D can achieve 99.99% disinfection of all viruses and bacteria."

The UV disinfection robot is said to work by generating UV light energy that changes the DNA structure of an infectious cell, minimising its capacity to reproduce and eliminating them to colonise and harm patients.

Tru-D enables hospitals to kill pathogens such as Clostridium difficile (C diff), methicillin-resistant Staphylococcus aureus (MRSA) and carbapenem-resistant Enterobacteriaceae (CRE).

Bon Secours St Mary’s Hospital chief medical officer Dr Khiet Trinh said: "The acquisition of this technology is simply another way that we’re working to protect the integrity of our healthcare environment, and ultimately safeguard the well-being of every single patient who walks through our doors."

Bon Secours Virginia provides services, including cardiac, women’s, children’s, orthopaedics, oncology, neurosciences and surgery.
