<p>A storage receptacle sealing and transfer apparatus is disclosed for selectively enabling sealing and transfer of material to and from the receptacle. The apparatus is particularly useful for maintaining and later transferring drug and associated materials, under sterile conditions, to achieve mixing, as, is necessary, for example, in reconstituting a drug by mixing the drug with a diluent prior to delivery to a patient. The transfer apparatus (200) is mounted at the aperture, or mouth, (62) of a storage receptacle (10) to seal the aperture until the contents are needed, and then to permit sterile transfer from the storage receptacle to another receptacle (35) through a central passage (257). The apparatus also includes venting through one or more passages (140) offset from the central passage for supplying or discharging air into the storage receptacle as needed, and a filter (100) is included in each vent passage, with the filter being permeable to passage of gases, including air, in either direction through the vent passage, but precluding passage of fluid, solid materials or microorganisms in either direction through the vent passage.</p> |
