System and Apparatus for Item Management Including Item Detection
Item-management systems, apparatus, and methods are described, preferably for management of items such as medicaments. In embodiments, an item-management system comprises a portable medicament container including plural cells, a docking station to which the container is temporarily docked, a sensor guide which may overlie the container when docked, visible information sources providing visible information to indicate cell into which each medicament is to be hand-loaded, and at least one controller operable to control the visible information. The sensor guide provides for medicament or item detection and for positive feedback confirming that the medicament or other item has been loaded into the correct cell.
1 . A medicament-management system which enables a pharmacy user to rapidly and accurately perform repetitive tasks of hand-loading medicament container cells with medicaments, the system comprising:
a portable medicament container including plural cells each defining a cell upper opening through which a medicament is hand-loaded into the cell;
a docking station to which the container is temporarily docked for hand-loading;
a sensor guide which overlies the container when docked, the guide including plural openings each in alignment with one of the container cells and a sensor associated with each opening which detects passage of a medicament through the opening toward the container cell and generates a signal responsive to the detection;
visible information sources providing yes state or no state visible information, a source being associated with each guide opening to indicate by the yes state the opening and aligned cell into which each medicament is to be hand-loaded; and
at least one controller operable to control the visible information to indicate the opening and cell into which the medicament is to be hand-loaded, receive the signal from the sensor, and generate a further signal if the medicament is not detected as expected, thereby enabling the pharmacy user to rapidly and correctly perform the repetitive manual tasks of hand-loading the cells with a correct type of medicament.
2 . The system of claim 1 wherein the sensor guide rests on the container when in use.
3 . The system of claim 2 wherein the sensor guide is apart from the container when not in use.
4 . The system of claim 1 wherein each sensor includes:
a sender which emits a signal;
a receiver across the opening from the sender which receives the signal; and
the medicament is detected when the signal is interrupted by the medicament passing through the opening.
5 . The system of claim 4 wherein the sensors are inside the sensor guide.
6 . The system of claim 1 wherein the sensor guide openings are entirely through the sensor guide.
7 . The system of claim 6 wherein the sensor guide includes a plurality of light pipes entirely through the sensor guide, a light pipe being associated with each opening to provide the visible information on the sensor guide.
8 . The system of claim 7 wherein the docking station includes a plurality of light sources with aligned light pipes extending from the light sources to a top of the docking station, a docking station light pipe being associated with each cell of a docked container and in alignment with each sensor guide light pipe to provide the visible information from the docking station, through the container, and to the sensor guide.
9 . The system of claim 8 wherein:
the container is a blister package and the cells are arranged in a pattern; and
the docking station includes a plurality of cell-receiving pockets arranged in a pattern matching the pattern of the blister package cells such that the blister package nests within the pockets when docked.
10 . The system of claim 9 further including a closure which closes the cell upper openings after medicaments are loaded in the cells to provide a self-contained, sealed container.
11 . The system of claim 8 wherein:
the container is adapted to transfer the medicaments to an automated dispensing machine; and
the container includes a plurality of light pipes positioned entirely through the container, each container light pipe being in alignment with a docking station light pipe and a sensor guide light pipe when the container is docked, to provide the visible information from the docking station to the sensor guide.
12 . The system of claim 11 wherein each cell of the container has a cell lower opening through which a medicament is discharged from the container and a closure which closes and opens the cell lower openings.
13 . The system of claim 1 wherein the controller is further operable to access information indicating the cell in which each medicament is expected.
14 . The system of claim 13 wherein the controller controls the visible information for the cell in which the medicament is expected responsive to the information.
15 . The system of claim 14 wherein the controller generates a signal responsive to the medicament being detected as expected.
16 . The system of claim 15 wherein the controller is further operable to control the visible information of the cell for which the medicament is not detected as expected, thereby identifying the cell to a user.
17 . The system of claim 16 wherein the controller is further operable to blink the visible information of the cell for which the medicament is not detected as expected.
18 . The system of claim 15 wherein the signal generated by the controller if the medicament is not detected as expected includes an error description.
19 . The system of claim 18 wherein the error description is selected from the group of descriptions consisting of an overcount, an undercount, and incorrect cell.
20 . The system of claim 19 wherein (a) the signal responsive to the medicament being detected as expected and (b) the error description are displayed to a user on a video display when appropriate.
