Ouch, that's excessive (price wise, and if you need to change out multiple times a day that's expensive)... All you should really need is a non-adherent dressing, and then whatever you need for gauze or to cover. Antibiotic cream or whatever optional too.
I've used things like this for things like gunshot wounds/stabbings/shrapnel/etc. Pretty much anything where you want to keep/have a wet scab so it heals faster, and want to allow for drainage.
