Believe me, it is a stupid idea....
While it is possible to obtain fully waterproof power receptacles to
IP67, see http://www.marechal.com/En/sc_5/05_pn.html they can only be
obtained as an integral plug and socket pair and the method of operation
is not a simple insertion and pull out arrangement found generally
equipment with power cords. Note that the Marechal PN is only for
surface mounting. In order to mount this unit in the floor would require
some sort of floor box recessed into the tiled concrete floor which you
would commonly find in a hospital OR. Even if the electrical safety
authorities would allow such a floor mounting, which I am sure they
wouldn't, then this method would only be economically viable in a new
building in my opinion.
Now consider the fact that if you did have a recessed box in the floor
to house the beautiful IP67 rated power receptacle, - how do you stop
water getting into the box itself? This means that the box housing the
receptacle also has to be IP66 or IP67 rated. There is a possibility
that the floor box may just happen to be open and water gets in and
floods it, - how do you drain it? Obviously it could only be drained by
resort to tedious manual exercise of sponge and bucket and not one which
the cleaner would appreciate having to perform.
Since the plug and socket are special types every item of electrical
equipment likely to be plugged into that outlet would have to be
retro-fitted with the special plug so this is going to be an expensive
replacement project in itself.
Now here is the real cruncher... no electrical safety authority would
approve of power receptacles being mounted in a OR floor, even IP67
rated ones, even if you could get flush mounted ones. An OR by its very
nature is classified as a "WET" area and is frequently scrubbed, washed
etc with copious amounts of water and/or other fluids. Any electrical
safety authority would reject the concept out of hand even knowing that
IP67 outlets were available simply because it could not be absolutely
guaranteed that the outlet would retain its IP67 rating indefinitely. It
would only take one occurrence of electric shock in an OR to totally
ruin the reputation of the hospital concerned and also bring great scorn
and ridicule on the electrical safety authority which allowed such a
I think by now you should have gained an impression that your suggestion
does not have a snowball's chance in hell of happening....
