Inline liquid drug medical device having rotary flow control member

摘要

Inline liquid drug medical devices for use with a source of physiological fluid and a medicinal vessel for liquid drug reconstitution and administration purposes. The inline liquid drug medical devices include a housing having a longitudinal device axis, a rotary flow control member and a vial adapter for transposing the flow control member from an initial first flow control position for liquid drug reconstitution purposes to a second flow control position for liquid drug administration purposes. The inline liquid drug medical devices include a syringe port and a drug dispensing port co-axial with the device axis. The rotary flow control member is rotatable about an axis of rotation co-axial with the syringe port and the drug dispensing port.

1. An inline liquid drug medical device for use with a source of physiological solution and a medicinal vessel for reconstitution and administration of a liquid drug, the inline liquid drug medical device having a longitudinal device axis, and comprising:
a) a housing including a first port for fluid connection with the source of physiological solution, and an integrally formed port manifold having a peripheral port manifold surface and a drug dispensing port for liquid drug administration, said first port and said drug dispensing port being co-axial with the device axis, said port manifold including a minor flow duct transverse to the device axis extending radially from said first port to said peripheral port manifold surface, and a bore transverse to the device axis and in flow communication with said drug dispensing port; b) a rotary flow control member having a second port, an inner wall facing said port manifold and an axial liquid drug administration channel, said rotary flow control member being rotatable on said port manifold about an axis of rotation co-axial with the device axis, said first port and said drug dispensing port from an initial first flow control position for establishing flow communication between said first port and said second port for liquid drug reconstitution purposes to a subsequent second flow control position for establishing flow communication between said first port and said drug dispensing port via said axial liquid drug administration channel and said bore for liquid drug administration purposes; and c) a manually rotatable vial adapter for snap fitting onto the medicinal vessel and including an elongated upright stem for initial engagement with said flow control member in said initial first flow control position in an initial liquid drug reconstitution position of said vial adapter, said vial adapter having a fluid conduit co-directional the device axis and lateral thereto, said fluid conduit having a proximal end in flow communication with said second port and a distal end in flow communication with a puncturing cannula extending into the medicinal vessel on attachment to said vial adapter in said initial liquid drug reconstitution position, said vial adapter being manually rotationally detachable from said housing along a line of detachment co-directional with the device axis for simultaneously transposing said flow control member from said initial first flow control position to said subsequent second flow control position.
