Abstract

An automated supplies cabinet dispenses supply items that are stored in a rack of drawers within a locking cabinet. A robotic transfer mechanism fetches the drawer containing the desired supply items, and brings it to an access portal at the front of the cabinet. A sliding door opens automatically to provide access. The supply articles can be RFID tagged and an RFID reader provides for automatic inventory updating when the articles are taken. The racks can take the form of carts that wheel into place in the cabinet. A light curtain disposed at the access portal can block movement of the door and of the transfer mechanism if it detects a hand reaching in. The cabinet provides an audit trail and facilitates inventory control and patient billing.

Claims

1. A controlled supply cabinet arrangement in which supply items are stored in respective drawers from which said items can later be removed by a user without removing the respective drawer from the supply cabinet, comprising

at least one rack of drawers, said drawers being disposed in respective spaces that are arrayed vertically in said rack;

said drawers being slidable horizontally out of and into the respective spaces, and each of said drawers having a drawer pull thereon, each of said drawers containing at least one of said supply items;

a secure locking enclosure in which said rack of drawers is disposed, and having an interior defining a vertical shaftway adjacent said rack of drawers;

the enclosure having a front wall with an access door therein, the access door being situated adjacent said shaftway and alongside said at least one rack;

wherein each of said at least one rack of drawers is configured as a cart having wheels permitting the rack to be moved by rolling it horizontally into and out of said secure locking enclosure; and

wherein said enclosure includes a locking door that permits the cart to be rolled horizontally into place therein;

a transport mechanism movable vertically in said shaftway for fetching a selected one of said drawers, bringing the drawer to the access door where the user can remove one or more of said supply items from said drawer, and thereafter returning the drawer to its respective space in the rack;

the transport mechanism including

a platform disposed for vertical movement in said shaftway;

grip means on said platform for grasping the drawer pull of the selected drawer;

means for moving the grip means to draw the drawer out from its respective space in the rack, and thereafter pushing the drawer back into such space;

means slidably supporting the drawer; and

means for controllably raising and lowering the platform and drawer; and

a processor storing the identity of the contents of each said drawer and the location of the respective space for each said drawer, including control means for automatically directing the transport mechanism to the selected drawer, and causing the transport mechanism to bring the drawer from its respective space in the rack, present the selected drawer at said access door, and thereafter return the drawer to its space in the rack.

2. The controlled supply cabinet arrangement according to claim 1, wherein said supply items in said drawers are fitted with RFID devices, and said controlled supply cabinet arrangement further comprising an RFID reader situated at said access opening and coupled to said processor for detecting and identifying the supply items that are taken from said selected drawer and removed through said access door.

3. A controlled supply cabinet arrangement according to claim 1 further comprising means associated with said processor for requiring entry of an access code to identify persons authorized access to the cabinet, and requiring entry of said access code before actuating said transport mechanism.

4. A controlled supply cabinet arrangement according to claim 1 comprising network interface means addressable to said cabinet to permit a networked computer to control access to a plurality of cabinets.

5. A controlled supply cabinet arrangement in which supply items are stored in respective drawers from which said items can later be removed without removing the drawer from the cabinet, comprising

at least two racks of drawers, said drawers each being adapted to contain at least one supply item, and said drawers being disposed in respective spaces that are arrayed vertically in each of said racks;

said drawers being slidable horizontally out of and into the respective spaces, and each of said drawers having a drawer pull thereon;

a secure locking enclosure in which said racks of drawers are disposed, the racks being situated facing one another and defining a vertical shaftway between the racks and adjacent said racks of drawers;

the enclosure having a front wall with an access door therein, the access door being adjacent and alongside said shaftway;

a transport mechanism movable vertically in said shaftway adapted for fetching a selected one of said drawers from either of the racks of drawers that are facing each other adjacent said shaftway, bringing the drawer to the access door, and thereafter returning the drawer to its respective space in the respective rack;

the transport mechanism including

a platform disposed for vertical movement in said shaftway;

grip means on said platform for grasping the drawer pull of the selected drawer from either of said racks;

means for moving the grip means to draw the drawer out from its respective space in the rack, and thereafter pushing the drawer back into such space;

means slidably supporting the drawer; and

means for controllably raising and lowering the platform and drawer; and

a processor storing the identity of the contents of each said drawer and the location of the respective space for each said drawer, including control means for automatically directing the transport mechanism to the selected drawer, and causing the transport mechanism to bring the drawer from its respective space in the rack, to present the selected drawer at said access door, and thereafter to return the drawer to its space in the respective rack.

6. The controlled supply cabinet arrangement according to claim 5, wherein each said rack of drawers is configured as a cart having wheels permitting the rack to be moved by rolling it horizontally;

and wherein said enclosure includes a locking door that permits the cart to be rolled into place therein.

7. The controlled supply cabinet arrangement according to claim 5, comprising a touch screen access computer mounted thereon.

8. The controlled supply cabinet arrangement according to claim 5, comprising means connecting said processor to a main supply computer.

9. The controlled supply cabinet arrangement according to claim 8, wherein the supply items in said drawers are fitted with RFID devices, and said controlled supply cabinet arrangement further comprising an RFID reader situated at said access opening and coupled to said processor for detecting and identifying the supply items that are taken from said selected drawer and removed through said access door, the RFID reader being coupled via said processor to said main supply computer, thereby to furnish continuously updated data concerning the contents of the supply cabinet arrangement.

10. The controlled supply cabinet arrangement according to claim 5, further comprising a light curtain disposed at said access opening, and including a light transmitter at one side of the access opening, a receiver arrangement situated at an opposite side of said access opening to detect a break in the light generated at said light transmitter, and means for disabling said transport mechanism when such break is detected.

11. The controlled supply cabinet arrangement according to claim 5, further comprising means for detecting the presence of an object penetrating said access opening, and means for disabling the transport mechanism during any time that such penetration is detected.

12. The controlled supply cabinet arrangement according to claim 11, comprising a vertically movable sliding door at said access opening, including means for automatically opening and closing said sliding door, and means for disabling movement of said vertical sliding door when penetration is detected.

13. The controlled supply cabinet arrangement according to claim 5, wherein said transport mechanism comprises a set of vertical rails that guide said platform vertically in said shaftway, said platform includes a set of transverse guides, a carriage that travels slidably thereon, with said grip means being mounted on said carriage and adapted to pull out and push in the drawers in either of said racks that face one another on either side of the shaftway, and drive mechanism for controllably moving said carriage on said transverse guides.
