Syringe mixer and injector device

Claim 2

Syringe mixer and injector device comprising an injector and an adapter, each having an inner end and an outer end and a protected fluid pathway extending longitudinally therethrough from the inner end to the outer end thereof, the injector inner end having a connection nozzle defining the inner terminus of the injector pathway and the adapter inner end having a counterpart connection nozzle defining the inner terminus of the adapter pathway, the nozzle and counterpart nozzle having mating lock connection formations arranged to interconnect releasably the injector and adapter to flow connect their pathways in protected fluid tight condition, the injector and adapter each having a guideway extending from the outer end toward the inner end thereof, adapted to receive and guide for movement longitudinally relative thereto a respective medicament containing vial having an open end closed by a penetrable stopper movable longitudinally along the vial relative to its open end, and the injector and adapter each having a connecting socket defined in the outer end thereof, adapted to connect stationarily the corresponding stopper thereat, and a tubular spike defining the outer terminus of the pathway thereof and protruding into the respective socket and terminating inwardly from the respective outer end sufficiently to protect the spike from unintended human contact and arranged to penetrate the corresponding stopper to flow connect its vial with the respective pathway in protected fluid tight condition.

Claim 3

Device of claim 1 wherein each socket defines an axial cylindrical recess and each spike defines an axial hollow cylindrical tubular portion centrally arranged coaxially with its respective recess.

Claim 4

Device of claim 2 wherein each spike is cantilevered and has a pointed free end and a base end which is integral with the adjacent portion of the corresponding end of the injector and adapter through which the respective pathway extends.

Claim 5

Device of claim 1 wherein the injector and adapter are formed of plastic.

Claim 6

Device of claim 4 wherein the injector and adapter are each respectively formed as a separate injection molded, integrally connected one-piece member.

Claim 7

Device of claim 5 wherein the injector includes a generally hollow exterior part having an open outer end and an inner end containing the connection nozzle and further containing an inner end portion of the pathway, the inner terminus of the pathway being defined by the connection nozzle, and the injector further includes an interior part having an outer end containing the socket and being provided with the remaining portion of the pathway, the interior part being disposed in the exterior part and being welded thereto whereby to flow connect the inner end portion of the pathway with the remaining portion thereof in fluid tight condition.
