FIELD: medical equipment.
SUBSTANCE: invention relates to devices for selective selection of liquid from a medicinal product vial. The device contains a valve and a compressible plug. The vertically mounted valve and plug form the connecting part. When the syringe is connected to the sealing device, the syringe compresses the stopper, which, in turn, opens the hole located in the central part of the valve neck. When the medicinal product is removed from the vial, the medicinal product enters the valve and passes through the central neck, from where it exits through its open holes and then enters the syringe itself.
EFFECT: when the syringe is removed, the stopper expands or straightens, which again closes the holes located in the central neck of the valve, thereby stopping the flow of the drug through the sealing device.
