Hospitals being cleaned by UV light robot

Humans v/s Machines Humans 0 Machines 1. Humans v/s Robots Human 0 Robots 1...and so it continues

According to an Indian-origin scientist's study, a Star Wars-style robot that uses ultraviolet light can clear upto 70% if bacteria in hospital rooms in under 15 minutes. This study looks at how effective the germ zapping robot can be to clean hospital rooms which could be the answer to preventing the spread of "superbugs" and in turn saving not just so much of money but also so many lives.

It is vital for hospital rooms to be kept clean to prevent infections spreading between patients. Hotel roof surfaces like tray tables, bedrails, call buttons and even handle railings can be reservoirs for methicillin-resistant Staphylococcus aureus (MRSA), which are not just hard to treat but in stray cases even fatal.

Chetan Jinadatha, Assistant Professor of Health Science Center College of Medicine at Texas A&M University, said "A typical 100-bed hospital sees about 10-20 hospital-acquired infections a year". The goal is to get to zero infections.

At present, hospital room cleaning is done by housekeeping staff who, often have a high turnover rate, where the Indian researcher aims to use technology to prevent these hospital-acquired infections. The researcher is also studying the effectiveness of a pulsed xenon ultraviolet (UV) light system which was developed in Texas.

This robot bears a striking resemblance to a fictional robot in Star Wars called R2-D2 which has a large saucer-shaped head on top of a column that rises to reveal a bulb filled with xenon gas. When the system comes on, high-voltage electricity passes through the bulb releasing a spectrum of UV light which binds the DNA of organisms killing them. Jinadatha's latest study, looked at how effective UV light disinfection is by itself. The study found that in just 12 minutes, a xenon UV light system cuts the amount of bacteria in the room by 70% which amounts to approximately the same level of effectiveness as a manual disinfection. The researcher lays emphasis on the fact that he would never recommend the hospital use the UV light system alone, as he doesn't feel it possesses enough of a "safety net" to kill bacteria which traditional cleaning may miss.
