An apparatus for preparing an aseptic preparation for administration, comprising: a flexible container containing a physiological diluent; a valved connector in a wall of said container and including: a connector body formed with a piercing needle, a tubular stem insertable through said wall of said container, and means displaceable into a first position for connecting a port of said body to said needle, a second position for connecting said needle with said container and blocking communication with said port, and a third position blocking communication between said needle and said container and blocking communication between said port and said container; a sterile filter on said connector communicating between said port and the atmosphere; and a vial having a sealing membrane pierceable by said needle and adapted to be received by said connector over said needle, whereby in said first position of said valve said filter communicates with said vial and communication of said container with said vial and said filter is blocked, and sterile air from the atmosphere is admitted through said filter into said vial to bring a pressure in said vial to atmospheric pressure, thereafter in said second position of said valve said vial communicates with said container and communication of said vial and said container with said filter is blocked so that squeezing said container at least once displaces diluent from said container into said vial and a mixture of diluent and said medicament from said vial into said container, and in said third position, mixture from said container is prevented from reentering said vial.
Claim 7
Independent Claim
258 words
An apparatus for preparing an aseptic preparation for administration, comprising: a flexible container containing a physiological diluent; a valved connector in a wall of said container and including: a connector body formed with a piercing needle, a tubular stem insertable through said wall of said container, and means displaceable into a first position for connecting a port of said body to said needle, a second position for connecting said needle with said container and blocking communication with said port, and a third position blocking communication between said needle and said container and blocking communication between said port and said container; a sterile filter on said connector communicating between said port and the atmosphere; and a vial having a sealing membrane pierceable by said needle and adapted to be received by said connector over said needle, whereby in said first position of said valve said filter communicates with said vial and communication of said container with said vial and said filter is blocked, and sterile air from the atmosphere is admitted through said filter into said vial to bring a pressure in said vial to atmospheric pressure, thereafter in said second position of said valve said vial communicates with said container and communication of said vial and said container with said filter is blocked so that squeezing said container at least once displaces diluent from said container into said vial and a mixture of diluent and said medicament from said vial into said container, and in said third position, mixture from said container is prevented from reentering said vial.
