Vial and syringe combination

Claim 1

A device for storing and administering a medicament, comprising: syringe means including a barrel having an elongated sleevelike end portion of reduced diameter, said end portion of reduced diameter having a discharge opening therethrough communicating with the interIor of said barrel; perforable seal means blocking said discharge opening, said seal means being spaced inwardly from the outer end of said discharge opening as defined adjacent the free end of said reduced diameter end portion; vial means defining a chamber therein and having an elongated sleevelike part of reduced diameter, said sleevelike part having a flow opening therethrough communicating with said chamber; perforable stopper means blocking said flow opening, said perforable stopper means being spaced inwardly of said opening from the outer end thereof as defined adjacent the free end of said sleevelike part; elongated double ended cannula means extending between said syringe means and said vial means, said cannula means having one end portion thereof loosely but slidably disposed within said reduced diameter end portion, the other end portion of said cannula means being loosely but slidably disposed within said reduced diameter sleevelike part; support means disposed in surrounding relationship to said cannula means and fixedly secured thereto at a location disposed between the ends thereof, said support means including a portion disposed in snug, slidable, telescopic engagement with said reduced diameter end portion; releasable detent means coacting between said portion of said support means and said reduced diameter end portion for resisting movement of said cannula means relative to said syringe means; removable tubular sheath means surrounding said cannula means and extending between said syringe means and said vial means for connecting same together, said sheath means including a first annular end portion having first and second sleevelike parts of different diameters disposed in surrounding relationship to said barrel and said reduced diameter end portion, respectively, and disposed in snug slidable engagement therewith; said sheath means including a second annular end portion having first and second sleevelike parts of different diameters disposed in surrounding relationship to said reduced diameter part and said vial means, respectively, and disposed in snug slidable engagement therewith, whereby said sheath means can be slidably disconnected from both said vial means and said syringe means; and releasable detent means coacting between said reduced diameter part and said sheath means for resisting movement of said sheath means relative to said vial means.

Claim 2

A device for storing and administering a medicament, comprising: syringe means including a barrel having an elongated sleevelike end portion of reduced diameter, said end portion of reduced diameter having a discharge opening therethrough communicating with the interIor of said barrel; perforable seal means blocking said discharge opening, said seal means being spaced inwardly from the outer end of said discharge opening as defined adjacent the free end of said reduced diameter end portion; vial means defining a chamber therein and having an elongated sleevelike part of reduced diameter, said sleevelike part having a flow opening therethrough communicating with said chamber; perforable stopper means blocking said flow opening, said perforable stopper means being spaced inwardly of said opening from the outer end thereof as defined adjacent the free end of said sleevelike part; elongated double ended cannula means extending between said syringe means and said vial means, said cannula means having one end portion thereof loosely but slidably disposed within said reduced diameter end portion, the other end portion of said cannula means being loosely but slidably disposed within said reduced diameter sleevelike part; support means disposed in surrounding relationship to said cannula means and fixedly secured thereto at a location disposed between the ends thereof, said support means including a portion disposed in snug, slidable, telescopic engagement with said reduced diameter end portion; releasable detent means coacting between said portion of said support means and said reduced diameter end portion for resisting movement of said cannula means relative to said syringe means; removable tubular sheath means surrounding said cannula means and extending between said syringe means and said vial means for connecting same together, said sheath means including a first annular end portion having first and second sleevelike parts of different diameters disposed in surrounding relationship to said barrel and said reduced diameter end portion, respectively, and disposed in snug slidable engagement therewith; said sheath means including a second annular end portion having first and second sleevelike parts of different diameters disposed in surrounding relationship to said reduced diameter part and said vial means, respectively, and disposed in snug slidable engagement therewith, whereby said sheath means can be slidably disconnected from both said vial means and said syringe means; and releasable detent means coacting between said reduced diameter part and said sheath means for resisting movement of said sheath means relative to said vial means.
