ABSTRACT:
Suction transfer assembly for a medicament liquid, formed of a vial having a chamber filled with the liquid and an open end closed by a penetrable stopper on which the vial is slidable longitudinally, and an adapter having a front end with a nozzle lockably connectable to a mechanical probe-containing counterpart nozzle of a suction device, e.g. a syringe, a rear end with a hollow needle, and an internal flow path therebetween. The adapter rear end is insertable into the vial open end and fastenable to the stopper for penetrating the stopper by the needle. The adapter front end has a mechanical probe-openable and self-closing check valve in the flow path adjacent the nozzle so that on locking the counterpart nozzle thereto, its probe opens the valve for suction transfer of liquid from the vial to the device and simultaneous compensating vial movement relative to the stopper under external atmospheric pressure to reduce the chamber volume by an amount generally equal to the liquid transferred.
