Abstract
A device for breaking various size ampules at the ampule neck, which is the most convenient break point for extracting the fluid from the ampule. The ampule breaker comprises a formed structure having a wedge surface which contacts the ampule at the neck and sides adjacent to the wedge which are contoured to contact the extremities of the appendage to be broken off from the ampule. The contoured sides extend beyond the point where the extremities contact so that no matter which size ampule is inserted into the breaker, a mechanical advantage is provided to help break the ampule appendage. A staggered set of cover plates are used to retain the ampule appendage during and after breaking.
