UV light robot destroys coronavirus in 2 minutes
Japan distributor Terumo eyes broader sales for hospital disinfection

A machine that uses ultraviolet light to disinfect hospitals has been shown
to deactivate the novel coronavirus in just two minutes, providing a
potentially effective method of removing the virus from public spaces.

Texas-based Xenex Disinfection Services recently announced a successful
test of its LightStrike robot against the virus. The robot, sold in Japan
by medical equipment maker Terumo, emits light of wavelengths between 200
and 315 nanometres to decontaminate beds, doorknobs and other surfaces.

Two or three five-minute rounds of ultraviolet radiation leave pathogens
too damaged to function. The technology has been proven to work against
multidrug-resistant bacteria and the Ebola virus, according to Xenex.

The LightStrike robot was also shown to be 99.99 per cent effective in
eliminating the coronavirus from N95 masks, which would reduce the risks
associated with reusing vital protective equipment amid an acute global

The machines have been introduced in about 500 healthcare
facilities worldwide.

Terumo was granted exclusive distribution rights in 2017. The devices,
which go for about ¥15m ($140,000), had been deployed in 11 facilities by
the end of April and interest has been growing from hospitals seeking to
avoid spreading the disease.

“Between March and April, we had inquiries from more than 100 medical
institutions,” a Terumo representative said.
