ABSTRACT:
Apparatus for sterilizing objects with a gaseous ethylene oxide held in a sealed ampule of the type including a breakable section, includes a cartridge for holding the sealed ampule in a substantially immovable manner, the cartridge including a first chamber for containing the ampule, a second chamber for holding an absorbent cotton material to hold the liquid sterilant upon breaking open of the ampule, the first and second chambers being in communication with each other, a transverse bore extending into the first chamber and outlet openings in the second chamber; a push-button slidably movable in the transverse bore for breaking open the ampule upon depression of the push-button in the transverse bore, wherein, upon breaking open the ampule, the gaseous sterilant escapes from the ampule through the outlet openings into sterilizing contact with the objects; a releasable guard for preventing slidable movement of the push-button in the transverse bore to prevent breaking of the ampule; and a liner bag for holding the cartridge and the objects to be sterilized in a sealed manner.
