Abstract
Abstract A drug vial mixing and transfer device having a piercing connector or a syringe attached to the end of one or more ports with interconnecting fluid passageways. Further, the piercing connector is used to support and penetrate standard glass drug vials filled with powder or lyophilized drugs or liquid diluent, while the syringe is used to transfer liquid diluent and drug solutions between the vials and the syringe advantageously within a sealed system.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
159 words
A drug mixing and transfer device comprising: a base; a valve attached to said base; a plurality of ports with fluid passageways extending generally outwardly from said valve, said valve enabling fluid communication between the fluid passageways of said plurality of ports; a piercing connector attached to each of said plurality of ports, said piercing connector being adapted to receive and penetrate a vial and to retain the vial in place during operation of the drug mixing and transfer device; a retainer attached to said base and located in spaced relation to said piercing connector, said retainer being adapted to maintain the vial in spaced relation with said piercing connector prior to operation of the drug mixing and transfer device; and a syringe attaching port having a fluid passageway and extending generally outwardly from said valve, said valve enabling fluid communication between the fluid passageway of said syringe attaching port and the fluid passageways of said plurality of ports.
Claim 2
Dependent Claim
159 words
A drug mixing and transfer device comprising: a base; a valve attached to said base; a plurality of ports with fluid passageways extending generally outwardly from said valve, said valve enabling fluid communication between the fluid passageways of said plurality of ports; a piercing connector attached to each of said plurality of ports, said piercing connector being adapted to receive and penetrate a vial and to retain the vial in place during operation of the drug mixing and transfer device; a retainer attached to said base and located in spaced relation to said piercing connector, said retainer being adapted to maintain the vial in spaced relation with said piercing connector prior to operation of the drug mixing and transfer device; and a syringe attaching port having a fluid passageway and extending generally outwardly from said valve, said valve enabling fluid communication between the fluid passageway of said syringe attaching port and the fluid passageways of said plurality of ports.
Claim 3
Dependent Claim
22 words
