Plaster recommendation for palm of hand

Looking for plaster recommendation

I've got to keep a small surgical wound clean and dry for 2 weeks but the plaster applied in the clinic of course came off and ones I have to replace it come off after 30 minutes only..the tiniest amount of sweat behind them..and off the come.

Googling sweat proof plasters just brings me to waterproof ones , I'm quite capable of keeping the area dry. So it's not waterproof I need , it's sweat proof (from the inside of the plaster) not waterproof from the outside.
