Description




BACKGROUND AND SUMMARY OF THE INVENTION




The present invention relates generally to the dispensing of items, such as drugs, and more particularly, a system and apparatus for the dispensing of items such as drugs, including an apparatus for storing, transporting, receiving, refilling, and tracking drugs through their channels of distribution.




It is known in the art to dispense drugs at a healthcare location or other care facility through an automated dispensing machine, for example, such as the one described in U.S Pat. No. 5,014,875. The entire contents of U.S. Pat. No. 5,014,875 are hereby incorporated by reference herein. As described in that patent, a pharmacist or pharmacist technician arranges for drugs to be moved to each automated dispensing machine and be manually placed into drawers, and more particularly, pockets within those drawers for later removal and administration by doctors and nursing staff. The patent referred to above describes the benefits of such an approach, as well as the drawbacks of previously known systems for accomplishing similar purposes.




The apparatus of the present invention comprises a unique receptacle having a bottom and a plurality of sides and an attached top that may be actuated to open to expose the contents of the receptacle. The receptacle further includes an information storage device, such as a memory chip, for storing information regarding the contents of the receptacle.




In a preferred embodiment, the receptacle includes an electronic actuated latch for the top opening that opens upon receipt of required information to be inputted by an operator. The latch affords a safety solution for the receptacle through the entire process of medication distribution, that an unauthorized person cannot gain access to the receptacle other than by vandalizing the receptacle.




The unique receptacle of the present invention may be adapted to reside in an automated dispensing machine along with a plurality of other like receptacles. The receptacles are preferably configured in such a way to allow for an efficient and optimum placement within the dispensing machine for access by an operator, such as a nurse or doctor or other authorized individual. In this embodiment, each receptacle preferably contains individual packages of particular drugs, drug kits, medical supplies, or combinations of these. Individual receptacles may have multiple types of drugs or medical supplies for one particular patient or a plurality of the same type of drug or medical supply for use with several patients. In this embodiment of the invention, the receptacles each contain associated hardware to support information about the contents of the receptacle in the automated dispensing machine. Likewise, the data entry device associated with the automated dispensing machine enables an operator to enter certain requested information, such as operator identification information or requested drug information or patient identification information, which will then be electronically transmitted to the appropriate receptacle within the automated dispensing machine which actuates the latch to open the top of the appropriate receptacle for access by the operator. All of the information for these transactions are maintained by the system, so that a record of the operator, patient, drug requested, receptacle accessed, etc. is available.




In another embodiment of the present invention, a system is described in which the receptacles are loaded with particular items at a batch facility then “programmed” with a memory chip containing information. Information about the items loaded into each receptacle may be stored in information storage devices that may be integral to each receptacle and/or information about the items loaded into each receptacle may be put in bar code form on a bar code label and placed on the receptacle. The receptacles with the items now contained within them are then closed and transported to a receiving station, such as a pharmacy at a healthcare facility. There, information regarding the contents of each receptacle may be obtained from the receptacle's information storage device. In another embodiment, information regarding the contents of each receptacle may be scanned with a hand-held scanner reading a bar code label that was placed on each receptacle at the batch facility. Data obtained from the information storage device and/or from scanning the bar code labels may be stored in a computer at the receiving station for inventory control purposes. The same computer at the receiving station may be in communication with automated dispensing machines, even though the automated dispensing machines may be at a remote location from the receiving station computer. As users/operators of the automated dispensing machine enter information to gain access to the contents of the receptacles within the automated dispensing machine, the operator-entered information may be delivered to the receiving station computer to maintain a real-time inventory of each receptacle in each automated dispensing machine. The receptacle's information storage device may also maintain real-time inventory of the receptacle's contents as users/operators gain access to the contents of the receptacle.




In another embodiment of the present invention, a manual refill cart is provided with a surface to receive receptacles. This refill device is used when filling receptacles with drugs from inventory (e.g., in the hospital pharmacy). The manual refill cart may have on board electronic connections for facilitating communication between each receptacle and a computer in association with the cart.




The manual refill cart may have a bar code scanner attached to it to scan the bar codes on the unit dose packages of drugs to be loaded into the receptacle. The information from the bar coded packages of drugs is transferred from the bar code scanner and into the computer of the refill cart and/or into the memory chip of the receptacle. This enables the memory chip to maintain the information about the items stored in the receptacle.




The present invention overcomes many of the disadvantages of known approaches to drug distribution. There is no manual operation needed for bagging or unbagging medications at the nurses station for later use with patients. The receptacle of the present invention may arrive at the nurses station ready for use with patients without further handling of the drugs until administration to the patient. The receptacle also allows for fewer human errors in drug handling. In known systems, a drawer of drugs may open exposing several pockets with different drug varieties. With the preferred embodiment of the present invention only one receptacle opens at a time exposing only the drugs in that receptacle. Loading of receptacles is safer too. Since typically only one type of drug would be placed in each receptacle there is less chance that a person loading that one type of drug will accidentally load a second variety in the same receptacle. Because the tops of the receptacles are preferably sealed closed until opened automatically upon receipt of an authorized signal at a delivery station, it greatly lessens the need for skilled staff to handle the receptacles. In other words, if the receptacle cannot be opened without proper receipt of signals from a delivery station, such as a dispensing machine, then there is less need to have sophisticated personnel for transport of the receptacles.




The present invention may also be an intelligent receptacle. In a preferred embodiment, information about the contents may be integral to the receptacle, such as by bar code or by electronic chip that is machine readable. This enables tracking of the contents, such as lot numbers and expiration dates of the contents, for example. When this information is ported to the dispensing machine and then to a central computer system, expiration dates of each drug in each receptacle may be monitored for replacement at the proper time.




A unique latch may also be employed with the receptacles. The latch may be comprised of bimetallic wire which contracts when it is heated by current. Upon contraction the wire pulls to one side and opens the latch allowing a spring to pop the lid open.




Several other features and advantages of the present invention will be readily apparent from the following detailed description of the invention, the attached drawings of the invention and the claims.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS




Referring now to the Figures, there is shown in

FIG. 1

a receptacle


30


of the present invention. The receptacle


30


has a plurality of sidewalls


32


that define a storage compartment


42


which is best shown in FIG.


2


. In

FIG. 2

, a top


34


is opened and closed about a hinge


40


. A latch assembly


38


is formed between the top


34


and one of the sidewalls


32


to keep the top in a closed position until an authorized operator gains access to the receptacle. The latch assembly


38


includes a latch member


44


and a latch receiving pocket


46


.




The receptacle


30


may be used to contain various items, for example, medications. Each receptacle may house multiples of one type of drug or medical supply or it may house several varieties of drugs or medical supplies in the storage compartment


42


. The receptacle of the present invention is adapted for use in a variety of systems. For example, it may be used at a patient's bedside table, on a medication cart, as a part of a drug administration kit in an operating room environment, or in many other scenarios both in and out of the medical industry. The invention has been described herein with reference to the medical industry but it is to be recognized that the invention has far reaching application in many industries.




The receptacle of the present invention may also be used as a removable return container for later disposing of items, such as used or discarded medicine administration items. The receptacle of the present invention may also be adapted for communication with one or more devices via one of several possible communication means. For example, the receptacle may communicate via a chip inside the receptacle that has been programmed with information, and the chip may be adapted for communication with another electronic device to download, or share the information. Another form of communication may be remote, such as via a RF proximity chip in the receptacle for RF communication with a RF station. Of course, the receptacle


30


may also be “dumb,” without on-board intelligence, and information about its contents may be contained within a bar code, for example, placed on the receptacle. In such an application of the invention, a receiving area of an apparatus, for example on or in an automatic dispensing machine, may acquire the necessary information through scanning of the bar code on the receptacle to enable the dispensing machine to know sufficient information about the contents of the receptacle. The receiving area may be a drawer in an intelligent dispensing machine having either an on-board computer processor or a connection to one remote therefrom.




In another embodiment, the receptacle


30


may have limited on-board intelligence. For example, the information storage device or the bar code label of the receptacle


30


may only contain information about the receptacle, such as the receptacle number (e.g., #1234567). This pre-programmed information would typically be entered when the receptacle


30


is filled. In this embodiment, a regular label (not a bar code label) or marking on the receptacle itself with the receptacle number may be used and the operator/user may manually enter the receptacle number into the computer having the pre-programmed information about the contents of the particular receptacle.




The receptacle


30


of the present invention may be refilled and reused many times in a preferred embodiment hereof. In a unique system of the present invention, a refill station may be provided for refilling each receptacle. If the receptacle is “intelligent”, it may be programmed with information at the refill station and the refill station may be so adapted to provide this communication to the receptacle. The refill station may be at a pharmacy or at a distribution center in the application of this invention to the medical industry.




The receptacle


30


may be made from injection molded plastic, or formed from metal and as such, may be durable and reusable multiple times. Alternatively, the receptacle


30


may be made from inexpensive, disposable materials for discarding after use.




The receptacle


30


, may also include a label


36


for identification of the contents within the receptacle and/or some or all of top


34


may be transparent. In

FIGS. 3 and 3A

, the receptacle


30


is shown in greater detail. The hinge assembly


40


includes a spring


48


and a pin


50


which join the receptacle compartment with the top


34


. While a hinged top is preferred, a sliding top may be used. The receptacle


30


may further include a compartment


58


for housing a latch assembly


52


. The latch assembly


52


may include a latch member


56


and a cover


54


.




The latch assembly is shown in greater detail in

FIGS. 4-7

.

FIG. 4

shows the latch member


56


in a closed position while

FIG. 5

shows the latch member


56


in an open position. A switch


57


may electronically inform an automated dispensing machine computer that the top


34


is in an open or closed position. A memory chip


62


may store information concerning the receptacle. This memory chip


62


may store a wide variety of information, including the data in the Hearst Corporation's National Drug Data File, as shown in Table 1, such as expiration date, lot number, NDC number, type of drug or medical supply dosage, size of packages, number of items in the packages, etc. The memory chip


62


can also store information about the receptacle


30


, including, when it was put in service, how many times it has been used, etc. This is beneficial because the receptacles


30


will have a limited useful life and it is desirable to take receptacles out of service before they fail (e.g., hinge breaks, latch breaks, etc.).




The receptacle


30


itself may be a medication package that contains drugs and a package insert. The receptacle


30


may replace bottles and other types of standard medication packages. An electrical communication contact


66


enables connection from the receptacle to a receiving location within an automated dispensing machine, thus facilitating communication between the receptacle and the computer associated with the automated dispensing machine. When required signals are received at the electrical contact


66


from the automated dispensing machine, an electronic circuit, such as the one shown in

FIG. 22

, actuates a muscle wire


64


causing the latch to be actuated and thus opening the top


34


. The muscle wire works by receiving a current and upon increasing in temperature the wire


64


pulls to one side by shrinking and thereby causes the latch to be susceptible to a spring force acting upon it from a spring in the hinge assembly


40


. The spring


48


pushes the top open when the latch is freed. In a preferred embodiment, the lid or top


34


will pop open about 15 degrees when the latch is opened.




An advantage of having the latch assembly as a separate component that can be removed from the receptacle


30


is that the latch assembly


52


and its components are more expensive and have a longer life expectancy than the storage compartment part of the receptacle


30


. Therefore, the latch assembly


58


can be reused if the rest of the receptacle cracks or breaks (e.g., hinge breaks, etc.). The latch assembly preferably cannot be removed unless the top is opened.





FIGS. 8 and 9

show a bottom portion of the receptacle


30


. Each receptacle may include legs


27


,


29


,


33


and


35


as well as a hook member


37


for engagement of the receptacle to a location, such as in an automated dispensing machine. Alternatively, the legs themselves may include catching or engagement features. An opening


39


enables contact by the electrical connection


66


with a port at the automated dispensing machine.





FIGS. 10-13

show other features of the present invention. In

FIGS. 10 and 11

, the receptacle


30


is shown stacked upon a similar receptacle


70


. Legs


72


and


74


of receptacle


70


may be designed to reside within a location within an automated dispensing, machine and/or within an area on a top surface of another receptacle. This allows for stacking of receptacles on each other for ease of storing and transportation.

FIG. 12

shows a double-wide receptacle


80


with top surfaces


82


,


84


and latch


86


.

FIG. 13

shows the interior compartment of receptacle


80


as well as hinge assembly


88


. It is to be appreciated that the receptacles may come in a variety of sizes and shapes according to the particular use and storage location they are intended for. The receptacles are preferably modular in design to enable them to be used in combination, for example in a drawer of an automated dispensing machine, with several other similar receptacles, fitting in close proximity to one another to efficiently use the space available in each drawer.





FIGS. 14

,


14


A and


14


B show views of the receptacles of the present invention installed within an automated dispensing machine


110


. Zones or locations


100


within a drawer


114


of the dispensing machine


110


are adapted to receive receptacles, such as receptacle


102


. A terminal display


112


may be provided with the machine


110


to enable an operator to review displayed information. A keypad


113


may be provided at the dispensing machine


110


to enter certain required information. A docking station


104


may be provided at the dispensing machine


110


for receiving receptacles, such as receptacle


102


within engagement receiver


126


, leg receivers


120


,


122


and electrical port


124


. In this manner, each receptacle, such as receptacle


102


, may be docked at the machine


110


to enable certain information stored with in the memory of the receptacle to be downloaded into a processor or computer associated with the machine


110


. If the receptacle


102


is to be loaded into a drawer


114


of the dispensing machine


110


, the drawer


114


may pop open to allow the receptacle


102


to be loaded into the correct zone


100


of the drawer


114


.




Within each drawer


114


, there may reside a tray


115


for holding receptacles


99


, etc. Individual zones


100


are adapted to receive individual ones of said receptacles. Spring assemblies


130


,


128


function in a manner to be described hereinafter. The spring assembly


128


is shown in greater detail in

FIG. 15B

to include springs


136


and


138


.




Zone


100


shown in

FIG. 15A

also includes pockets


133


,


135

and


18


show the insertion, locking, and release, respectively, of a receptacle


142


being placed into a drawer tray


115


. A nested or adjacent receptacle


140


is also shown already in place. Compression spring


143


is shown in its relaxed state in

FIGS. 16 and 18

and is compressed and not in view in FIG.


17


. Latch member


145


is shown in cross section view in contact with electrical circuit


151


. Latch engagement member


150


is shown in

FIG. 16

in a position ready to receive the retaining hook


152


of engagement member


148


of receptacle


142


. As shown in

FIG. 17

, when the engagement member


148


is depressed into the area


149


(shown in FIG.


16


), it catches or engages the end


154


of latching engagement member


150


. In

FIG. 18

, latch engagement member


150


is actuated away from the engagement member


148


(moved to the right as shown in FIG.


18


), thereby releasing the connection between the engagement member


148


and the latch engagement member


150


which allows the spring


143


to return to its relaxed state pushing receptacle


142


up and out of zone


100


to enable an operator to remove the receptacle from the machine


110


. The actuation of the latch engagement member


150


away from the engagement member


148


may be done by a muscle wire mechanism such as in

FIG. 22

or by other suitable means.





FIG. 19

shows a drawer


114


with a track


160


and rail


162


that is adapted to reside within the machine


110


. Wires


164


lead from a processor within the machine


110


, along, for example, path


165


to each of the zones, such as zone


100


, to carry communication between the receptacles


30


and the machine computer.

FIGS. 20 and 21

show other views of the drawer


114


. In

FIG. 21

, a grid


168


may be installed along the rail


162


to be read by sensor


169


so that the computer aboard the machine


110


knows how far each drawer


114


has been pulled out of the machine, thereby exposing rows of receptacles


30


. The sensor


169


may be an optical sensor or other suitable sensor adapted to read the bars or grids of


168


and communicate that information via wires


166


and through wires


164


to the computer. In another embodiment, RF communication links may be used instead of or in addition to, wires


166


and


164


. In accordance with a preferred embodiment of the present invention, the drawer will be open before the top of the receptacle is popped open or the receptacle itself is popped up to be removed from the drawer.





FIG. 22

shows a preferred embodiment of an electrical wiring circuit for use with the latch assembly of each receptacle


30


. The circuit communicates with the muscle wire which controls the movement of the latch to enable the door to open on each receptacle. The inputs to the circuit may be from the computer onboard the machine


110


. When an operator enters required information to access a receptacle, the computer may send the necessary signal to the receptacle via the circuit to open the latch. As stated above, the latch may be opened by spring force applied when the muscle wire retracts under current to free the latch for movement.




In one preferred embodiment of the latch assembly of the present invention a microprocessor is used. The microprocessor may include an analog to digital converter (A/D) and a pulse width modulator (PWM). The PWM produces a fixed frequency, variable duty cycle output. It is fed into a RC filter which produces a DC voltage between zero and five volts, depending on the duty cycle. A voltage follower, n-channel FET, a bipolar transistor, or other kind of amplifier circuit is preferred to drive the muscle wire. The FET's are used to address a single muscle wire. The row drivers are p-channel FET's that supply the current generated by the voltage follower. The microprocessor outputs zero volts to the gate of the desired row and plus five volts to the rest. The column drivers are n-channel FET's that sink current to ground. The microprocessor outputs plus five volts to the gate of the desired column and zero volts to the rest. In a matrix of muscle wires, each wire has a diode in series with it to isolate it from the other muscle wires in the matrix. The current sense resistor generates a feedback voltage to the microprocessor proportional to the amount of current flowing in the muscle wire. The temperature sensor generates a voltage proportional to the ambient temperature.




The algorithm in the microprocessor is preferably structured as follows:




1. Select the desired row and column drivers.




2. Read temperature sensor.




3. Determine starting duty cycle and desired feedback target as a function of temperature (may be done via a look-up table).




4. Start the PWM generator.




5. Read the feedback voltage.




6. Compute error=(current feedback reading)−(desired target)




7. If error less than zero, the output current is too low, increase duty cycle.




8. If error greater than zero, the output current is too high, decrease duty cycle.




9. If error equals zero, do not adjust duty cycle.




10. If duty cycle cannot be increased, circuit may be broken. Shut off the PWM generator and report error to system.




11. If the duty cycle is below a predetermined threshold, there may be a short-circuit. Shut off the PWM generator and report error to system.




12. Check elapsed time since muscle wire was energized. If above desired time, shut off PWM generator.




13. Wait for PWM value to stabilize.




14. Go back to step 5.





FIG. 23

shows a group of configured receptacles


170


and


180


, for example. The top


172


is open exposing the internal compartment


174


and in this example, syringes containing a predetermined drug


176


are shown inside the compartment


174


. Visible on the surface of each top of each receptacle is a label with printed drug information on the label as well as a bar code containing additional information about the item contained within that particular receptacle.




It should be appreciated from the foregoing description that the present invention is useful in the medical drug and supply field, however, the present invention has applicability to a broad range of industries apart from the medical industry, where similar inventory control and security measures are preferred. The present invention is not intended to be limited to the medical supply and drug industry.





FIGS. 24-26

show three (3) respective system diagrams for system implementations of the present invention beginning with a wholesaler all the way to a patient's bedside. As shown in

FIG. 24

, the wholesaler receives the medications and fills the receptacles of the present invention with doses of the medications. These receptacles are then transferred to a pharmacy, such as a hospital pharmacy, where they are next loaded into an automated dispensing machine. From the automated dispensing machine, the medications may be removed by appropriate personnel from the receptacles and administered to a patient at the patient's beside. The lower portion of the diagram of

FIG. 24

shows a flow of information from the automated dispensing machine to the various computer systems in communication with the computer of the automated dispensing machine. For example, as

FIG. 24

demonstrates, information concerning drugs administered to patients may be communicated to a hospital pharmacy computer, the wholesaler's computer, and the packaging company computer.

FIG. 25

shows a similar diagram, however, in this implementation, the receptacles are not filled prior to the drugs arriving at the automated dispensing machine. Instead, the receptacles are refilled at the automated dispensing machine and arrive at the automated dispensing machine in unit dose packs.

FIG. 26

shows another embodiment of a system of the present invention in which unit dose packs and prefilled receptacles are delivered to the automated dispensing machine where some previously existing receptacles at the automated dispensing machine are swapped for new receptacles.




Many advantages are derived from the receptacle of the present invention. Another advantage is seen from

FIGS. 24-26

. Due to the self-contained nature of each receptacle, much of the processing and handling of receptacles may be done automatically. For example, in

FIG. 24

, an automated storage and transfer mechanism


200


may receive medications in packages and move the packages to a station where the receptacles are filled with the packages by robotics means.
