What about doing a sort of particle effect with the blood? Have it spray from a given location, in partially random directions and speeds, and give each of the particles a collision state, with stop collision. When the particle stops, put a blood splatter there (probably most easily done with a sprite), even if it's on a moving object. It might even be effective for slow-mo combat as well.
Just an idea I had. Not sure how effective it'd really be.
