SWMBO is still recovering from a nasty ulcer and is now into negative pressure wound therapy. AKA a pump that goes off every so often to help healing.
Trying to sleep with it, the noise isn't too bad. But the vibration ...
It's about 5cm square and would fit into some sort of gel pouch nicely. If such a thing existed.
As usual my google-foo is only telling me about isotonic drinks, or silica gel pouches. Neither of which is remotely close to what I picture.
Was wondering if there's a special name ?
I've already made one design improvement by ensuring the air tubes can't become accidentally disconnected. Something the fitting nurse said has been a problem for years. On the basis I would imagine most posters here would have done something similar, I do wonder WTF medical tech is so expensive. It's clearly not going on design.
