Fluid control device with manually depressed actuator

A fluid control device for use with a syringe and a vial for administering a liquid drug, the fluid control device comprising:

• (a) a housing having a longitudinal axis, a syringe port and a drug administration port co-directional with said longitudinal axis for correspondingly receiving the syringe and administrating the liquid drug, and a tubular vial adapter port intermediate said syringe port and said drug administration port;
• (b) a flow control member rotatably supported in said vial adapter port about an axis of rotation generally perpendicular to said longitudinal axis, said flow control member including an L-shaped mixing flow channel with a radial section for flow communication with said syringe port in a mixing flow control position and an axial section, said flow control member including a peripheral semi-circular administration flow channel for enabling flow communication between said syringe port and said drug administration port in a subsequent administration flow control position,
• (c) a vial adapter for telescopically receiving a vial and including an upright tubular male connector and a downward depending tubular cannula for extending into the vial and in flow communication with said male connector,
• said vial adapter being initially coupled to said housing for sealing insertion of said male connector in said axial section and being rotationally detachable from said housing whereupon rotation of said vial adapter relative to said housing simultaneously rotates said flow control member from said mixing flow control position to said administration flow control position,
• characterized in
• said flow control member including an axial extension to said L-shaped mixing flow channel's axial section thereby providing an axial throughgoing bore co-axial with said axis of rotation, and
• the fluid control device further comprising a manually depressed actuator with a manually depressed head and a downward depending shaft partially inserted into said throughgoing bore in an initial raised position of said actuator relative to said housing, and a pin-like plug partially inserted into said male connector for enabling flow communication between said syringe port and the vial in said initial mixing flow control position,
• the arrangement being such that depression of said manually depressed actuator toward said housing seals said L-shaped mixing flow channel's radial section and urges said pin-shaped plug to seal said vial adapter's male connector.
