Blood blister
a blister full of blood due to a pinch, bruise or repeated friction. A blister is medically termed a vesicle. One that is more than 5 mm in diameter with thin walls and is full of watery fluid is called a bulla or a bleb. The word "blister" entered English in the 14th century. It came from the Middle Dutch "bluyster", blister and was a modification of the Old French "blostre" which meant a leprous nodule — a rise in the skin due to leprosy.
