Why Choose UVC Disinfection?

Safe, Effective, Efficient.

Tru-D allows hospital staff to easily and confidently disinfect virtually any environment, including patient rooms, intensive care units, operating rooms, emergency rooms and public areas. The UV disinfection robot kills deadly pathogens and common health care associated infection culprits such as Clostridium difficile (C. diff), Methicillin-resistant Staphylococcus aureus (MRSA), carbapenem-resistant Enterobacteriaceae (CRE) and other bacteria that compromise patient outcomes.

What is UVC Light, and How Does It Kill Germs?

WHAT IS UV LIGHT?

Ultraviolet (UV) light is a form of light, invisible to the human eye, that exists on the electromagnetic spectrum between X-rays and visible light. We are exposed to low levels of UV light from the sun’s rays every day, although much of the UV energy is absorbed by the ozone layer.

WHY USE UV LIGHT TO DISINFECT?

UV light’s wavelengths are between 200 and 300 nanometers, making them germicidal – meaning they are capable of inactivating microorganisms, such as bacteria, viruses and protozoa. This quality makes UV light an effective, environmentally-friendly and chemical-free way to remove and reduce dangerous microorganisms in any environment, but especially in hospitals that contain drug-resistant superbugs including MRSA and C. diff.

HOW DOES UVC DESTROY GERMS?

The high energy from short wavelength UV light is absorbed in the cellular RNA and DNA, damaging nucleic acids and preventing microorganisms from infecting and reproducing. This absorption of UV energy forms new bonds between nucleotides, creating double bonds or “dimers.” Dimerization of molecules, particularly thymine, is the most common type of damage incurred by UV light in microorganisms. Formation of thymine dimers in the DNA of bacteria and viruses prevents replication and inability to infect.

WHAT TYPE OF UV LIGHT IS GERMICIDAL?

There are three UV light wavelength categories: UVA, UVB and UVC. Tru-D SmartUVC produces UVC, the only wavelength known to be germicidal. UVC utilizes short-wavelength ultraviolet radiation (shorter than UVB and UVA, which are NOT germicidal) that is harmful to microorganisms.

Broad Spectrum UV disinfection often claims to be more effective than short wavelength UVC, but ultimately wastes a considerable amount of energy with no documented increase in effectiveness – only short wavelength UV produces the amount of energy necessary to kill microorganisms.

PULSED AND UNMEASURED UV LIGHT

Xenon flash lamps and other unmeasured UV lights, while they may use UVC lamps, have no way of calculating the UV dose needed for each location to determine the positioning or time necessary to disinfect accurately, nor can they reach shadowed or hidden surfaces.

As distance from the lamp increases, effectiveness against microorganisms decreases sharply  – requiring multiple positioning around the room to achieve even partial disinfection.

MEASURED AND CONTINUOUS UV LIGHT

Tru-D is an automated, remotely-operated system that self-adjusts to the size and content dynamics of any room to deliver the proper dose of UV light energy necessary for complete terminal disinfection. Tru-D’s leading edge Sensor360™ technology uses instrument grade sensors to measure the UVC that is deflected into shadowed and indirect areas for a terminal disinfection. As energy is deflected around the room, shadowed areas are reached and pathogens are eradicated ensuring a thorough disinfection outcome, every time.

  • The ROI has been our increased confidence in our clean environment. In 2016, our C-Diff rate was 0.61. After we implemented UVC disinfection in 2017, it dropped to 0.18. Though actual cost savings from HAI avoidance can be difficult to quantify, we know from national statistics that HAIs...

  • Tru-D was the obvious choice because we wanted something that was easy to use and reduced the probability of human error. We love the fact that our Tru-D robot doesn’t need to be repositioned to disinfect a specific area within a room.

    Mary Parry

    COO of Oneida Health Systems

  • We strive to ‘stay ahead of the curve’ when it comes to patient safety, so when evaluating disinfection processes, UV application was a natural next step. Tru-D’s ability to assess the space and antimicrobial UV dosage was key in this decision.

  • Having Tru-D in our facility helps ensure we are providing the safest environment possible for our patients and staff. We are consistently looking for proactive measures that we can take to remain on the leading-edge of technology and patient safety. Our environmental staff does an excellent job with...

  • The acquisition of UV technology is simply another way that we’re working to safeguard the well-being of every single patient who walks through our doors and protect the integrity of our health care environment.

    Paul Gentile

    Infection Control and Prevention Coordinator at Charlotte Hungerford Hospital

  • Last year, our hospital had 81 cases of hospital-acquired C. diff. We’re on pace to have about one-third fewer hospital-acquired infections of all kinds this year, a decrease I attribute to the whole-room disinfection technologies we’ve added to our manual cleaning.

  • Using an iPad outside the room, our staff turns on Tru-D remotely and begins a single disinfection cycle. The robot is able to compensate for room variables such as size, shape and contents to deliver the precise dose of UV energy needed throughout the entire room. The technology...

    CEO of Frye Regional Medical Center

  • The Sensor360® technology set Tru-D apart. Rather than estimating the necessary UV dose or moving a unit to multiple placements in a room, Tru-D is able to analyze a space and provide a measured, lethal dose of UV light to provide total room disinfection from a single cycle...
