Before removing the prosthetic I gently rinse off the blood. Since the make-up has been set it shouldn't wash off. It might fade slightly but that can be retouched when it's applied again at a later time.
After rinsing I remove the prosthetic by rolling the edges towards the center of the wound. Latex tends to stick to itself after curing, so powdering it with talc or baby powder will prevent this. Removing the latex should be relatively easy and painless unless it has been caught in some hair. Do not use any oil based products to remove the latex piece as the oil will break down its structure. You can purchase silicon oil that will remove latex and leave it intact, although shiny. The silicon oil is often expensive and not worth the trouble.
And there you go... you know have a re-usable prosthetic application of a wound that can easily be used at a later time. Although you will need to purchase some spirit gum (and spirit gum remover) to attach the piece to your skin. With a little Liquid Latex to blend the edges and some touch ups on the make-up, the wound can be ready to go again in no time.
