Described is a device for release of a substance from a solid preparation thereof to a flowing liquid during simultaneous parenteral administration of the liquid to a patient, which device comprises a connector (1) connectable into a system for parenteral administration of the liquid, and having an inlet (6) and an outlet (12) for the liquid and means for liquid communication of said inlet and outlet with a valve device (4, 5) which comprises a mobile valve core (5) having a bypass position providing for direct liquid flow from the inlet to the outlet of the connector and a working position providing for liquid flow from the inlet (6) of the connector into a releasable container (15) for the solid preparation. The device is characterized in that the valve core (5) has an outlet means (13A) and a separate inlet means (19A) simultaneously connectable to an inlet means (14) and a separate outlet means (18) respectively on the releasable container, the releasable container further having therein means (16) for conducting the liquid from the inlet thereof to a space where it will contact the solid preparation (17), and further to the outlet of the releasable container (18), and via the valve core in a flow path to the outlet (12) of the connector. |
