Drug storage and delivery system

Claim 1

A storage and delivery system for a flowable substance, comprising: (a) a vial having a threaded opening, a wall portion and an end portion constructed and arranged to contain a flowable substance; (b) a pierceable stopper in sealing engagement with said opening in said vial whereby the flowable substance may be extracted from said vial through a needle inserted into said vial through said stopper; (c) a syringe assembly having a generally cylindrical housing and a cannula supported in said housing and extending longitudinally therethrough along an axis thereof; (d) an adapter assembly including an adapter member for attaching said vial to said syringe assembly so as to permit communication between the interior of said vial and said cannula extending through said syringe; (e) a skirt member frictionally engaging said wall portion of said vial, said skirt member having ratchet means associated therewith that cooperates with complementary ratchet means associated with said adapter member upon attachment of said adapter assembly to said vial so as to thereafter prevent disengagement of said vial from said adapter assembly; (f) a lock member for attaching said adapter member to said syringe assembly wherein said adapter member releasably engages said lock member; (g) a needle hub member associated with said adapter member and supporting said needle that pierces said stopper as said adapter member is attached to said vial, said vial opening being threaded with said needle hub member threadedly receiving said threaded opening as said adapter member is attached to said vial; and (h) a fitting portion that cooperates with said lock member to provide fluid communication between said needle and said cannula as said adapter member is attached to said lock member.

Claim 9

A system for separately storing and subsequently mixing the contents of at least two containers in one of the containers, said system comprising: (a) a first container having an opening, a wall portion and an end portion constructed and arranged to contain a first substance, said first container having a pierceable stopper in sealing engagement with said opening whereby the contents of said first container may be extracted therefrom through a needle inserted thereinto through said stopper; (b) a second container having an opening, a wall portion and an end portion constructed and arranged to contain a flowable second substance, said second container having a pierceable plug in sealing engagement with said opening whereby the contents of said second container may be extracted therefrom through a cannula inserted thereinto through said plug; (c) a syringe assemby having a generally cylindrical housing and a cannula supported in said housing and extending longitudinally therethrough along an axis thereof, said syringe assembly having a first end portion attachable to said second container so as to permit communication between the interior of said second container and a first end of said cannula as said end extends through said plug; and (d) an adapter assembly means including an adapter member with complementary ratchet means for attaching said first container to said syringe assembly so as to permit communication between a second end of said cannula and the interior of said first container through a needle inserted through said stopper; and (e) a skirt member frictionally engaging said wall portion of said first container, said skirt member having ratchet means associated therewith that cooperates with complementary ratchet means associated with said adapter member upon attachment of said adapter assembly to said first container so as to thereafter prevent disengagement of said first container from said adapter assembly.

Claim 10

A system for separately storing and subsequently mixing the contents of at least two containers in one of the containers, said system comprising: (a) a first container having an opening, a wall portion and an end portion constructed and arranged to contain a first substance, said first container having a pierceable stopper in sealing engagement with said opening whereby the contents of said first container may be extracted therefrom through a needle inserted thereinto through said stopper; (b) a second container having an opening, a wall portion and an end portion constructed and arranged to contain a flowable second substance, said second container having a pierceable plug in sealing engagement with said opening whereby the contents of said second container may be extracted therefrom through a cannula inserted thereinto through said plug; (c) a syringe assemby having a generally cylindrical housing and a cannula supported in said housing and extending longitudinally therethrough along an axis thereof, said syringe assembly having a first end portion attachable to said second container so as to permit communication between the interior of said second container and a first end of said cannula as said end extends through said plug; and (d) an adapter assembly means including an adapter member with complementary ratchet means for attaching said first container to said syringe assembly so as to permit communication between a second end of said cannula and the interior of said first container through a needle inserted through said stopper; and (e) a skirt member frictionally engaging said wall portion of said first container, said skirt member having ratchet means associated therewith that cooperates with complementary ratchet means associated with said adapter member upon attachment of said adapter assembly to said first container so as to thereafter prevent disengagement of said first container from said adapter assembly.
