Medical devices including vial adapter with inline dry drug module
First Claim
1. A medical device for use with a needleless syringe, a vial and a carrier liquid for filling the needleless syringe with an injection solution for injection to a patient, the needleless syringe having a male connector, the vial having a vial stopper and a vial interior, the medical device having a longitudinal device axis and comprising:
- (a) a vial adapter having a skirt with downward depending flex members for telescopic mounting on the vial, a puncturing cannula for puncturing the vial stopper on said telescopic mounting for flow communication with the vial interior and a central upright female connector in flow communication with said puncturing cannula and intended for connection to the male connector;
characterized by(b) an inline dry drug module disposed inline between said female connector and said puncturing cannula, said inline dry drug module including a dry drug storage component storing a dry drug dosage and a uniform carrier liquid distribution component for promoting uniform contact of said dry drug storage component by said carrier liquid on aspiration of carrier liquid from the vial through the inline dry drug module directly to the needleless syringe to form the injection solution.

Abstract
Medical devices including a vial adapter with an inline dry drug module for use with a vial, a needleless syringe and a carrier liquid for filling the needleless syringe with an injection solution for injection to a patient. The inline dry drug modules include a dry drug storage component for storing a dry drug dosage and a uniform carrier liquid distribution component for promoting uniform contact of the dry drug storage component by the carrier liquid to form an injection solution from the dry drug dosage. The inline dry drug modules can include a discrete dry drug storage component and a discrete uniform carrier liquid distribution component or a dual purpose component for both drug storage and uniform carrier liquid distribution. The vial adapters can be provided in vented or non-vented versions.
