Saw this today, who said water and electricity should not mixed. Fascinating how this could be applied.

Need to work out how inexpensive and durable it is but definitely a need!

i could imagine if used effectively, it could reduce LOS.
Personally, as someone who has had endured packing in a wound, and the discomfort from it use, this would be a much nicer option.
