Abstract
A device for release of a solid substance into a flowing liquid during parenteral administration of the liquid to a patient includes a connector (1, with an inlet (6) and an outlet (12) for the liquid, and a valve assembly (4,5). The valve assembly has a valve core (5) which is rotatable between a bypass position and a working position. A releasable container (15), containing the solid substance, may be connected to the valve core (5). In the bypass position, liquid is conducted from the inlet to the outlet, by-passing the container (15). When the valve core (5) is moved to the working position, liquid is diverted into the container (15), for mixing with the solid substance, and then returned to the connector, where it then exits through the outlet (12).
