Liquid drug transfer device with vented vial adapter
Liquid drug transfer devices including a vented vial adapter having a top wall, a downward depending skirt, and a dual lumen puncturing spike. The top wall includes vent apertures in flow communication with an underlying air filter and protective hoods for covering the vent apertures from splashes. The hood-like hoods are preferably quarter sphere shaped with hood apertures facing radial outwards.
1. A liquid drug transfer device for use with a medicinal vial including a bottle containing a medicament, a vial opening stopped by a vial stopper, and a narrow neck intermediate the bottle and the vial opening, the liquid drug transfer device comprising:
a vented vial adapter having a longitudinal vial adapter axis and including a top wall transverse to said longitudinal adapter axis, a cylindrical skirt having flex members resiliently attached to said top wall and downwardly depending therefrom for telescopically slidingly receiving the vial opening therein, an annular air filter disposed beneath said top wall,
said top wall having an upper surface and said cylindrical skirt having peripheral skirt surface, said upper surface meeting said peripheral skirt surface at an upper surface edge,
a downwardly depending dual lumen puncturing spike for puncturing the vial stopper for establishing flow communication with the bottle interior said puncturing spike having a base adjacent said top wall and a puncturing tip, said puncturing tip including a pair of axial directed lumens extending from said base to said puncturing tip, said pair of axial directed lumens including a liquid transfer lumen and a vent lumen,
a liquid transfer port in flow communication with said liquid transfer lumen, said liquid transfer port extending upwardly from said upper surface opposite said cylindrical skirt,
at least two spaced apart axially directed vent apertures formed in said top wall and in flow communication with said vent lumen via said air filter,
said liquid transfer port and said at least two spaced apart vent apertures being in flow communication with the bottle on slidingly receiving the vial in the vial adapter,
wherein said top wall is formed with a corresponding number of at least two discrete protective hoods at said at least two vent apertures extending upwardly from said upper surface, opposite said cylindrical skirt, such that each of said at least two vent apertures is individually covered by a discrete protective hood in a top plan view of said vented vial adapter along said longitudinal vial adapter axis and each of said at least two discrete protective hoods (i) has a hood aperture facing radially outwardly with respect to said longitudinal vial adapter axis, and (ii) is visible in a side elevation view of said vented vial adapter intercepting said upper surface edge such that liquid contents inadvertently disposed on said upper surface of an inclined vented vial adapter are diverted around a discrete protective hood for draining over said upper surface edge and down said peripheral skirt surface, thereby inhibiting said inadvertently disposed liquid contents from inadvertently entering the corresponding vent aperture covered thereby and wetting said air filter.
2. The device according to claim 1 , wherein each said protective hood has a quarter sphere shaped protective hood.
3. The device according to claim 1 , further comprising a manually placed cap for sealing said liquid access port.
4. A liquid drug transfer device for use with a medicinal vial including a bottle containing a medicament, a vial opening stopped by a vial stopper, and a narrow neck intermediate the bottle and the vial opening,
the liquid drug transfer device comprising a vented vial adapter having a longitudinal vial adapter axis and including a top wall transverse to said longitudinal axis, a cylindrical skirt having flex members resiliently attached to said top wall and downwardly depending therefrom for telescopically slidingly receiving the vial opening therein, an annular air filter disposed beneath said top wall,
a downwardly depending dual lumen puncturing spike for puncturing the vial stopper and establishing flow communication with the bottle interior, said puncturing spike having a base adjacent said top wall and a puncturing tip, said puncturing tip including a pair of axially directed lumens extending from said base to said puncturing tip, said pair of axially directed lumens including a liquid transfer lumen and a vent lumen,
a liquid transfer port in flow communication with said liquid transfer lumen,
at least one axially directed vent aperture formed in said top wall and in flow communication with said vent lumen via said air filter,
said liquid transfer port and said at least one vent aperture being in flow communication with the bottle on slidingly receiving the vial in the vial adapter
wherein said top wall is formed with a corresponding number of at least one quarter-sphere shaped protective hood at said at least one vent aperture, such that each of said at least one vent aperture is individually covered by a protective hood in a top plan view of said vented vial adapter along said longitudinal vial adapter axis and each of said at least one protective hood has a hood aperture facing-radially outwardly with respect to said longitudinal vial adapter axis.
5. The device according to claim 4 , further comprising a manually placed cap for sealing said liquid access port.
