Abstract
Syringe mixer and injector device formed of an injector and an adaptor having opposed interconnectable nozzles, e.g. with mating luer lock connectors, on their facing ends and sockets in their remote ends. Each of the injector and adapter has a protected fluid pathway flow connecting its nozzle and socket, a guideway to receive at its remote end for movement thereon a medicament vial when the vial stopper is connected to its socket, and a recessed short tubular spike forming the pathway portion in its socket and protruding into the socket and terminating inwardly from its remote end sufficiently to protect the spike from unintended human contact and arranged to penetrate the stopper thereat to flow connect its vial with its pathway in protected condition. After charging the injector connected vial with the contents of the adapter connected vial, e.g. by one-way transfer thereto, the injector nozzle may be disconnected from the adapter nozzle and connected directly without modification to a dispensing device having a like nozzle to that of the adaptor. Each of the injector and adapter may be made of plastic as an integral one-piece member.
