ABSTRACT:
An ampoule breaker comprises a body member capable of being held in a person's hand and having a hollow end portion constructed of flexible, resilient material. The end portion has an open end adapted to receive an ampule head and is formed with slots extending axially from the open end. The slots permit the end portion to be compressed between a person's fingers so that an ampule head located in the end portion can be firmly held therein and broken off by manipulation of the breaker. The slots comprise two generally V-shaped slots located on diametrically opposite sides of the end portion with the narrow end of each slot being disposed away from the open end. At least the end portion is made of cut-resistant flexible plastic.
