Abstract

A controlled access pharmaceutical storage cabinet has at least one pull-out drawer that is divided into a number of locked compartments, arranged in rows. Each row of compartments can be configured as a slide-out tray. A slide bar lock is positioned between rows of the compartments, and has a series of slots along each edge which align with lock pins on hinged lids or covers for the compartments. Only one compartment can be opened at a time. A gear-motor is provided for each slide bar to move the slide bar to a position for access to a given compartment. A locking hinged front door panel can swing down to allow the trays to slide out under the locked lids for refilling or replacement.

Claims

1. A controlled access pharmaceutical storage case comprising a frame and at least one pull-out drawer slidably supported in the frame of the cabinet;

said drawer including

a plurality of storage trays which are divided into individual bins, which define compartments arranged in at least one row in a given direction across said drawer and with said drawer including at least one elongated channel portion extending in said given direction alongside one of said trays, and being associated with one row of compartments of said one tray;

said drawer including a cover over said plurality of storage trays, the cover being formed as an array of at least one row of lids such that each of said storage compartments has an associated lid that is normally locked down but is selectively releasable to permit the lid to open for access to the compartment;

each said lid having a hinge pin at a rear portion thereof to permit the lid to pivot from a lowered closed position to a raised open position; and

a lock pin extending from one edge of said lid into said channel portion;

lid unlock means disposed in said channel portion and having a moveable member with slots thereon that align at different positions thereof with the respective lock pins of selected ones of said compartment lids, such that the selected compartment lid in which the lock pin aligns with its respective slot may be lifted open, but the remaining lids in that row of lids are blocked from opening;

controlled motor means for actuating said lid unlock means to selected positions to align a given slot of the movable member with the lock pin of the selected one of said compartments to permit the associated lid to be lifted open but to lock each of the other compartments in said row from opening; and

a swing-open drawer front panel hinged at a front of the drawer, including a pivoting hinge and a lock, the front panel being adapted to be locked in an upright position at the front of said panels, and which can be unlocked and rotated down to permit the storage trays to be slid out the front under said cover without raising any of said lids.

2. A controlled access pharmaceutical cabinet of claim 1, wherein said swing open drawer front panel is a drop-down panel, and said pivoting hinge is configured as a horizontal hinge.

3. A controlled access pharmaceutical cabinet of claim 1, wherein said moveable member includes a slide bar disposed in the channel portion and adapted to move for at least a limited distance along said channel portion, said slide bar having slots along at least one edge thereof that align with respective lock pins of the associated compartment lids.

4. A controlled access pharmaceutical cabinet of claim 3 wherein said motor means is controlled to move said slide bar only when said drawer is closed, and is inhibited from moving said slide bar when said drawer has been pulled open.

5. A controlled access pharmaceutical storage case comprising a frame and at least one pull-out drawer slidably supported in the frame of the cabinet;

said drawer including a plurality of elongated storage trays, each tray having a row of compartments wherein the trays are arranged such that at least one pair of parallel rows extend in the direction from back to front of said drawer; and

an elongated channel portion extends in the back to front direction between the rows of said pair of rows of compartments, and each of said trays being slidable into and out of said drawer, said trays being retained behind a front panel of said drawer;

each of said storage compartments having a lid that is normally locked down but is selectively releasable to permit the lid to open for access to the compartment;

each said lid having a hinge pin at a rear portion thereof to permit the lid to pivot from a lowered closed position to a raised open position; and

a lock pin extending from one edge of the lid into said channel portion;

a slide bar disposed in said channel portion and adapted to move for at least a limited distance along said channel portion, said slide bar having slots along each of its side edges which slots align with the respective lock pins of said compartment lids when said slide bar is moved to different respective positions along said channel portion, and such that any compartment lid in which the lock pin aligns with its respective slot may be lifted open, but the remaining lids in that pair of rows are blocked from opening;

controlled motor means for moving said slide bar to selected positions to align, at each selected position, a given slot of the slide bar with the lock pin of a selected one of said compartments to permit the associated lid to be lifted open but to lock each of the other compartments in said pair of rows from opening; and

wherein said front panel includes a swing-open drawer front panel hinged at a front of the drawer, including a pivoting hinge and a lock, the front panel being adapted to be locked in a closed position at the front of said panels to retain the slidable storage trays in the drawer, and which can be unlocked and rotated out to permit the slidable storage trays to be slid singly out the front from under said lids.

6. A controlled access pharmaceutical cabinet of claim 5 in which said swing-open front panel is a drop-down panel with said pivoting hinge being configured with a horizontal axis, such that the closed position of the panel is an upright position.

7. A controlled access pharmaceutical cabinet of claim 5 in which said storage trays comprise two or more pairs of rows of said compartments, with a respective said channel portion extending between the rows of each pair of rows.

8. A controlled access pharmaceutical cabinet of claim 7, said controlled motor means including respective gear motors situated at a distal wall of said drawer and coupled to one said slide bar associated with a respective pair of rows of said compartments.

9. A controlled access pharmaceutical cabinet of claim 8 wherein each said slide bar has a gear rack affixed onto a distal end thereof, and each said gear motor has a pinion meshing with the gear rack of the associated slide bar.

10. A controlled access pharmaceutical cabinet of claim 5, each said channel portion including a slide-bar cover mounted over the associated slide bar, said slide-bar cover having slot openings at locations of said lock pins.

11. A controlled access pharmaceutical cabinet of claim 5, wherein said motor means is controlled to move said slide bar only when said drawer is closed, and is inhibited from moving said slide bar when said drawer has been pulled open.

12. A controlled access pharmaceutical cabinet of claim 5, comprising a control arrangement suitably programmed with audit trail software for recording each time of opening of the lid of any of said compartments and also recording identity of each person associated with such openings of such lids.
