Germ-zapping UV robot...

Post by chaggle » Mon Oct 26, 2015 6:09 pm

... used for disinfecting medical rooms.

It's in Natural News but I suppose that doesn't automatically mean it's bollocks.

I can't find any links to formal trials - they all lead to the company marketing site. Maybe the google fu will be stronger in others on a Sunday morning...

Well I haven't googled anything but just reading the article raised my hackles. Mike Adams really is a piece of work.
So lets start with the Ebola angle he shoehorns into his article.

Horrible as ebola is, one thing it isn't is very highly contagious. it is not airborne like smallpox; it does not linger on surfaces like swine flu. Catching Ebola is actually quite difficult.

Here's a trusted source: http://www.nhs.uk/conditions/ebola-viru ... virus.aspx

How does it spread among people?

People can become infected with the Ebola virus if they come into contact with the blood, body fluids or organs of an infected person.
Most people are infected by giving care to other infected people, either by directly touching the victim's body or by cleaning up body fluids (stools, urine or vomit) that carry infectious blood.
Traditional African burial rituals have also played a part in its spread. The Ebola virus can survive for several days outside the body, including on the skin of an infected person, and it's common practice for mourners to touch the body of the deceased. They only then need to touch their mouth to become infected.
Other ways people can catch Ebola are:
touching the soiled clothing of an infected person, then touching their mouth
having sex with an infected person without using a condom (the virus is present in semen for up to seven weeks after the infected person has recovered)
handling unsterilised needles or medical equipment that were used in the care of the infected person
A person is infectious as long as their blood, urine, stools or secretions contain the virus.
Ebola virus disease is generally not spread through routine social contact (such as shaking hands) with patients who do not have symptoms.
The virus is not, for example, as infectious as diseases like the flu, as airborne transmission is much less likely. You'd need to have close contact with the source of infection to be at risk.
So as you can see "killing" the Ebola virus "commercial offices and even public schools." is neither difficult nor useful and to suggest otherwise is rampant scare mongering.

What is needed is something that "kills" ebola in people. In hospitals and quaritine centres you need do need equipment and procedures for handling and sterilising soiled clothing and medical equipment.

Typically medical equipment is sterilised in an autoclave. I don't see any claim that makes this new equipment better than the autoclave.

Moving past the Ebola angle it's clear that UV is a useful disinfectant and there are contagions that do need to be cleaned up in hospitals. There are issues such as how to deal with shadows. The obvious advantage of a robot is that it may do away with the human factor, however if human supervision is required to ensure that the robot manages to shine it's light into all the nooks a crannies then this advantage is less apparent.

However the advantage that Mr Adams cites is that its does away with harsh chemicals. Enough has already been said on chemophobia so I won't labour the point apart from highlighting the irony that one of the common bleaches and disinfectants used is hydrogen peroxide which elsewhere on the same site is not only being touted as safe to drink but a panacea capable of curing cancer!

For all I know the xenex robot is a great aid to clinical cleanliness, but the reasons that Mike Adams is providing are spurious claptrap.

Thanks for that Matt - it appears to be an opportunist 'Ebola' article - I suppose it won't only be Adams jumping on that bandwagon at the moment.

While reading it I got curious about the efficacy of the machine itself. It wouldn't be the first time that people you would expect to be more critical have been taken in by expensive bogus technology. I would like to see some live trial info for instance, as you point out, how good is it at ensuring the light gets everywhere?

In the same vein, it surprised me to discover that there is precious little evidence that Proton Beam Therapy is any more effective and safe that conventional radiotherapy yet many millions are being spent by the NHS on two centres.

Looks like it[s not just Mike Adams. http://news.discovery.com/tech/robotics ... 141011.htm

I suspect that xenex have put out a press release.

It's everywhere - The Mirror had it the other day...

http://www.mirror.co.uk/news/technology ... ls-4405653

... so yes - an Ebola inspired press release looks likely.

250 US hospitals have it and at 115,000 USD apiece that's.. um.. quite a lot.

Hope they work. Of course as long as they are complementary rather than alternative it doesn't really matter.

ETA - here is an article which gives some detail about testing.

I like the name "Germ-zapping UV robot" it has a great low-budget SF film vibe. Not as good as "Penis-Melting Zionist Robot Combs" however (worth using a popular search engine to look for).
