Abstract
Abstract A disposable syringe including a barrel having one medicinal solution therein and a cannula extending therefrom, and a vial removably attached to the barrel and receiving the cannula for isolated storage of a second medicament. With the barrel and vial in assembled, storage position, the syringe cannula tip is imbedded in a plug fixedly attached to the bottom wall of the vial, thereby preventing intermixing of the substances. However, when the parts are manipulated to a mixing position the cannula tip is withdrawn from the plug and air is introduced into the vial, thereby permitting a quantitative mixing of the substances under favorable pressure conditions. After mixing the syringe is removed completely from the vial, used in the regular manner, and the entire system thrown away.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
196 words
A unitized injection assembly comprising: a. a vial having an open end defining a combination first storage and mixing compartment; b. a hypodermic syringe including a second, storage compartment, a plunger reciprocable within said second compartment, and a cannula having a base, said base of the cannula including means for attaching said vial thereon with the cannula extending into the via; c. sealing means engageable with the free end of said cannula for isolating said first and second compartments from each other; d. said vial being movable relative to said syringe between a first, storage position in which the open end of said vial is engaged with the opposed, adjacent end of said syringe and the free end of said cannula is in engagement with said sealing means, thus forming a seal between said first and second compartments, and a second, mixing position with said open end of the vial spaced slightly from the opposed end of said syringe and the free end of said cannula withdrawn from said sealing means to permit communication between said first and second compartments; and e. a venting means for allowing air to enter the vial in said second position.
Claim 2
Dependent Claim
196 words
A unitized injection assembly comprising: a. a vial having an open end defining a combination first storage and mixing compartment; b. a hypodermic syringe including a second, storage compartment, a plunger reciprocable within said second compartment, and a cannula having a base, said base of the cannula including means for attaching said vial thereon with the cannula extending into the via; c. sealing means engageable with the free end of said cannula for isolating said first and second compartments from each other; d. said vial being movable relative to said syringe between a first, storage position in which the open end of said vial is engaged with the opposed, adjacent end of said syringe and the free end of said cannula is in engagement with said sealing means, thus forming a seal between said first and second compartments, and a second, mixing position with said open end of the vial spaced slightly from the opposed end of said syringe and the free end of said cannula withdrawn from said sealing means to permit communication between said first and second compartments; and e. a venting means for allowing air to enter the vial in said second position.
Claim 3
Dependent Claim
35 words
The injection assembly according to claim 1 wherein said sealing means comprises a plug fixedly mounted on the bottom wall of the vial, said plug being in alignment with the longitudinal dimension of said cannula.
Claim 4
Dependent Claim
65 words
The injection assembly according to claim 1 wherein said venting means comprises a passageway through the sidewall of said vial at a point on a level with said cannula base, said base blocking said passageway in said first, storage position and clearing said passageway in said second, mixing position, whereby the vial is vented in the mixing position to facilitate mixing of the substances therein.
Claim 5
Dependent Claim
29 words
The injection assembly according to claim 3 wherein indicating means are provided on said vial and said syringe to indicate the position of said base relative to said passageway.
Claim 6
Dependent Claim
33 words
The injection assembly according to claim 1 wherein said attaching means comprises external threads on said cannula base and mating internal threads on the inner wall of said vial adjacent said open end.
Claim 7
Dependent Claim
49 words
The injection assembly according to claim 1 wherein a first medicament is provided in said first compartment, and a second medicament is provided in said second compartment, said first and second medicaments being isolated from each other in said first position, yet permitted to mix in said second position.
