Abstract: A wet-dry syringe package including a syringe adapted to carry a liquid and a vial carrying a dry medicament with cooperating adapters provided on the syringe and vial for telescoping action whereby the syringe needle will be embedded in the vial stopper when the package is in the storage condition. Further movement of the syringe toward the vial causes the needle end to project through the vial stopper and establish fluid communication between the vial and syringe whereby the dry medicament and liquid are mixed. The mixture is then aspirated into the syringe and the syringe is freed of the package elements for ready use.

Abstract: An additive adapter for use in conjunction with an injector wherein the injector includes a cylindrical body having a rearward open end and a forward end necked inwardly to form an annular lip. The forward end having a central opening of reduced diameter which is closed off by a sealing diaphragm. A plunger is sealingly and slidably fitted in the rearward portion of the body to form a medicament chamber between the sealing means and the plunger. A needle hub is affixed to the annular lip and carries a needle which is in fluid communication with the medicament chamber upon the opening of the sealing diaphragm. The additive adapter comprises a main body portion including a cylindrical skirt portion extending from the rearward end of the cylindrical sleeve. The skirt is sized to snugly engage and fit over the forward portion of the injector's cylindrical body. A cylindrical shield having a diameter larger than the cylindrical sleeve extends from the forward end thereof.
