TECHNICAL FIELD
Embodiments generally relate to a device and method for docking a vial with a container.
BACKGROUND OF THE ART
Many medical fluids are typically manufactured and shipped in vials, which may have tamper-resistant, measurement, durability, and security features built in. Prior to using the fluid in a medical procedure, the fluid may need to be transferred to a different container. Thus, in various medical applications it may be desirable to create fluid communication between a vial and some type of alternate container (sometimes fluid bags such as intravenous bags), often referred to as ‘docking.’
SUMMARY OF THE EXEMPLARY EMBODIMENTS
An exemplary embodiment herein provides a device which can dock a vial with another container quickly, easily, and at low cost and low spatial footprint. The device preferably contains a cavity and optional notch which can accept at least a portion of the chosen container. A plate may be used to hold the vial overtop a cap or adapter, which may contain a piercing aperture for establishing fluid communication between the vial and the container. An exemplary plate may contain an aperture for holding the cap in place during the docking process as well as a notch for allowing the cap and at least a portion of the container to exit the device once the docking process has been completed.
In a preferred embodiment, a lever arm may be moved in a downward motion to cause a plunger to move in a corresponding downward motion. The plunger preferably contains a tapered collar which can accept and center the vial prior to pressing the vial into the cap. The cap may also have a tapered portion for accepting and centering the vial. An exemplary cap may also have a ledge which holds the cap securely in place atop the plate while the vial is being pressed down into the cap for docking.
The foregoing and other features and advantages of the present invention will be apparent from the following more detailed description of the particular embodiments, as illustrated in the accompanying drawings.

DETAILED DESCRIPTION
FIG. 1 is a perspective view of an exemplary embodiment of the device 100. A base 65 and vertical support 35 may provide a frame for the device 100. A plate 40 is preferably placed above the base 65 and rests upon a first base member 50 and second base member 55. The space defined by the area between the base 65, plate 40, vertical support 35, first base member 50, and second base member 55 may define a cavity 60, which can accept at least a portion of the chosen container to be docked with the vial 25. Preferably, the portion of the plate 40 which is opposite the vertical support 35 contains a cutout or notch 45 to allow at least a portion of the chosen container to pass through prior to and after the docking process.
In some embodiments, an adapter or cap 30 may be used to dock the vial 25 with the chosen container. If an adapter or cap 30 is used, the plate 40 would preferably contain an aperture 41 for accepting the cap 30. A lever arm 10 may be hingedly connected to the vertical support 35. The lever arm 10 may also be connected to a plunger 15 such that a downward motion of the lever arm 10 causes the plunger 15 to move downward as well. In the opposite direction, an upward motion on the lever arm 10 preferably causes an upward motion by the plunger 15. The bottom portion of the plunger 15 preferably contains a collar 20 which accepts the vial 25. A head support 22 may be connected to the vertical support 35 and may be used to guide the plunger 15 as it travels through its upward and downward motions.
FIG. 2 is a perspective sectional view of the device 100. The collar 20 preferably contains a tapered aperture 21 for accepting and centering the vial 25 within the plunger 15. The aperture 41 within the plate 40 may accept the cap 30. Preferably, the aperture 41 is vertically aligned with the tapered aperture 21 in the collar 20 so that a downward motion of the lever arm 10 presses the vial 25 onto the cap 30. In some embodiments, the cap 30 may contain a piercing aperture 36 which may pierce a portion of the vial 25 when pressed into the cap 30. In this manner, the vial 25 may remain completely sealed until pierced by this portion of the cap 30. An exemplary cap 30 may also contain an attachment means 31 to establish fluid communication with the chosen container. In this particular embodiment, the attachment means 31 is a stem for accepting a tube or hose from the chosen container.
FIG. 3A is an illustration of an initial step in an embodiment for using the device 100 to dock a vial 25 with a container 200. In this embodiment, the container 200 is a fluid bag, commonly known in the art as a ‘mini-bag.’ Of course, the device 100 can be used with any number of container styles, shapes, and sizes. Here, the container 200 contains a tube 201 which is adapted to attach to the attachment means 31 of the cap 30. In this particular embodiment, the tube 201 is sized to slide overtop a stem which is used as the attachment means 31. In this embodiment, the cap 30 contains a ledge 33 which is sized and adapted to rest atop the plate 40. Also shown in this figure is the piercing aperture 36 within the cap 30. In this embodiment, the cap 30 also contains a tapered portion 32 for accepting and centering the vial prior to docking.
FIG. 3B is an illustration showing the container 200 and cap 30 being placed within the device 100. In this embodiment, a portion of the container 200 is permitted to pass through the notch 45 in the plate 40 so that the cap 30 can rest within the aperture 41. To prevent the cap 30 from moving vertically during the docking process, the ledge 33 of the cap 30 should preferably rest on the top surface of the plate 40. The cavity 60 may also contain at least a portion of the container 200 during this embodiment of the docking process.
FIG. 3C is an illustration showing the vial 25 being placed within the device 100 for docking with the container 200. In this embodiment, the user may hold the vial 25 in place against the tapered portion 32 of the cap 30. FIG. 3D is an illustration showing the downward motion of the lever arm 10 and plunger 15 once the vial 25 has been captured by the collar 20. At this point, the vial 25 is preferably being pressed into the cap 30 so that the vial 25 may be docked with the container 200. In this particular embodiment, the vial 25 is preferably pierced by the cap 30 to establish fluid communication with the container 200. FIG. 3E is an illustration showing the upward motion of the lever arm 10 and plunger 15 following a successful docking procedure. FIG. 3F is an illustration showing a vial 25 that has been docked with a container 200 after removing it from the device 100. Here, the cap 30 and portions of the container 200 are permitted to exit the device 100 through the notch 45.
The device 100 can be constructed out of any number of materials, including but not limited to metals, plastics, composites, wood, or any combination of these. A preferred embodiment would be comprised primarily of plastics and an exemplary embodiment would be comprised primarily of HDPE.
