pleted, the lid opens automatically and

the mobile device can then be removed

with clean hands.

The device utilizes short-wavelength

ultraviolet light (UV-C), which destroys

nucleic acids and breaks apart germ DNA,

preventing them from being able to func-

tion or reproduce. While deadly to germs,

UV light won’t harm touchscreens, cam-

eras or IR sensors, and is optimal for hard,

non-porous surfaces.

The device can also sanitize multiple

items at once and includes RFID-enabled

tracking and compliance auditing. The

UV-C light does not dry out or degrade

materials, which occur with chemical

wipes, and can be safely used on a variety

of devices with no risk of damage.

Mobile devices are placed on a mov-

able chamber that transports the device

into a UV compartment, where the san-

itization occurs. After 20 seconds, the

device slides out, ready for use.

Designing the Sanitizer

Anand said the CleanSlate UV team faced

several significant challenges in design-

ing the device. “One of our biggest chal-

lenges in designing the product was the

lack of a uniform standard by which

countertop UV solutions would be

judged,’’ Anand said. “This was in large

part due to the infancy of the market. We

found that a lot of other solutions had cut

corners or taken the ‘easy route’ because

people may just not have known better.

Trying to determine where it was import-

ant to improve – versus what was ‘good

enough’ for most customers – was some-

times difficult given the number of stake-

holders in healthcare.”

The sliding chamber was a critical

component, and engineers found a lubri-

cation-free and maintenance-free solu-

tion from igus, the Germany-based

manufacturer of motion plastics. The

sanitizer includes igus’ DryLin W linear

guides, which slide, instead of roll, and

aren’t dependent of external lubrication.

“During the initial R&D stage, we

discovered that the UV lights must be on

and warm for effective sanitization in 20

seconds,’’ said Kevin Wright, the Cana-

dian sales manager for igus. “Since the

Plastic DryLin W linear guides, by igus, allow

the CleanSlate UV Sanitizer's sliding chamber

to quietly move devices to be cleaned to the

unit's disinfection chamber, without potential

contamination from lubricants.
