The bloodstopper looks like the Olaes without the pressure cup
Nope, a bloodstopper is just a quick-dressing. A Oales-bandage also has 4 yards of gauze and a occlusive layer build into it. It also has velcro on the bandage to make it extra secure.
I would go with the Oales-bandages.

EDIT: Pics added in the Olaes-bandage thread. (BTW: it's Oales-bandage, not Olaes-bandage. I misspelled
)
