Description




FIELD OF THE INVENTION




The present invention relates to a medication dispensing apparatus which contains a plurality of different kinds of medication (in this application the terms medication and medicament are used interchangeably) separately, dispenses the medicament to pack them into a package belt, and discharges the package belt, as well as a medication collecting system in which a medication dispensing station comprising the medication dispensing apparatus is disposed along a conveyor line and by which medication discharged from the medication dispensing station is placed onto a tray conveyed along the conveyor line and then collected.




BACKGROUND OF THE INVENTION




It is an idea disseminated in the 1960s in Japan that medication may be packaged in dosages and delivered to patients. This idea has been put into practical use mainly as packaging machines for powdered medicines. Tablet machines were developed in 1970s, and ampoule dispensing machines were developed in 1990s. These machines have been used in different ways according to their respective proper applications.




U.S. Pat. No. 5,604,692 discloses an apparatus in which a plurality of preparation stations classified according to the type of medication are arranged along a conveyor line and in which medicaments prepared at the individual preparation stations are collected to a checking station by the conveyor line. This apparatus prepares medicaments for the time period described in the prescription and delivers the medicaments to the patient.




In recent years, there has been developed an idea that medicaments prescribed to one patient are all collected regardless of the type of medicament and provided to the patient. This idea has been put into U.S. patent application Ser. No. 09/021864, the assignee of which is the same as one of the assignees of the present application.




In America, medicaments for one-day doses to be administered to inpatients are a packaged box in the dispensary, and the box is stored in a movable medication storage cabinet, for example, MEDSTATION marketed by Pyxis Co. With the medication storage cabinet provided in the nurse station, when the medicament administration time comes, medicaments are taken out from the medication storage cabinet and administered to patients. Upon completion of the medicament administration for one-day doses, the medication storage cabinet is returned to the dispensary medication storage cabinet in which medicaments for the next day have been stored is then moved to the nurse station. By adopting such a system, clear histories of administration to the patients can be obtained, allowing accounting, medicament inventory management and the like to be carried out collectively.




However, medicaments, particularly tablets, for one-day doses are packaged in the form of a continuous package belt. The package belt comprises a medication package portion in which one dose of tablet is packed, a print portion in which patient information, medicament information, dosage information and the like are printed, and an empty package portion which is inserted between different patients. This package belt arrangement necessitates troublesome work such as separating off medication packages for each patient or for each dose, or cutting off empty packages. In particular, in the case of, for example, medicaments to be ordered in operation rooms, CPUs, or emergency departments, it is desired that such work as the separation of medication packages and the cutoff of empty packages be achieved promptly for subsequent delivery of the medicaments.




SUMMARY OF THE INVENTION

is movable up and down along rails


107


by a belt chain


108


along a vertical Y-axis direction. Base


108




a


is equipped with a cylinder


109


. Also, a rod


109




a


of the cylinder


109


is equipped with a gripping arm


110


, which goes back and forth along a Z-axis direction perpendicular to the conveyor line


3


. The gripping arm


110


has at i-s front end a claw portion


110




a


formed for gripping a peripheral portion of the tray


9


(see also Japanese Patent Laid-Open Publication HEI 9-51922 etc.).




<System Operation>




Next, operation of the medication collecting system constructed as described above is explained.




When patient prescription information is read, a tray


9


is fed out from the tray feed station


1


to the conveyor line


3


. The tray


9


fed out to the conveyor line


3


is first conveyed to the tablet dispensing station


4


. If information indicating that tablets


23


are not contained in the prescription information, then the tray


9


passes through the tablet dispensing station


4


without stopping. If such information is contained, the tray


9


is stopped below the sloped plate


57


of the distributing member


48


.




For the prescription of the tablets


23


, at the tablet dispensing station


4


, one-day dose of medicaments are fed from the relevant tablet cassette


20


in steps of one dose one after another according to the dosage time, and then are packed into medication packages formed in the package belt


13


.




As for the form of package, if the one-day dosage includes a plurality of times, for example, morning, noon and evening, then medication packages


13




a


of the tablets


23


are continuously packaged as shown in FIG.


18


A. Alternatively, empty packages are formed between the medication packages


13




a


of the tablets


23


and the contents of the tablets


23


dosage information and the like are printed on these empty packages to make printed portions


13




b


as shown in FIG.


18


B. In the former case, as shown in

FIG. 18A

, the package belt is cut off by the cutter


29


with one-day doses taken as a unit. Thus, the need for bundling by the bundling machine


47


is eliminated. In the latter case, as shown in

FIG. 18B

, the package belt is cut off by the cutter


29


with one dose taken as a unit. In addition, with a different patient, two empty packages


13




c


are additionally formed between a printed portion


13




b


for patient A and a medication package portion


13




a


for the next patient B, thus enabling a continuous processing. Further, the empty packages


13




c


are separated from the other portions by the cutter


29


.




Subsequently, the cut package belt


13


is conveyed to the inverting member


44


via the direction changing part


33


and the conveyor


34


, so as to be transferred to the lifter


45


. For the package belt


13


or the empty packages


13




c


in the unit of one-day doses, the lifter


45


goes up without waiting for stacking by the transfer from the inverting member


44


; for the package belt


13


in the unit of one dose, the lifter


45


will not go up until one-day doses has been completely stacked by the transfer from the inverting member


44


. Then, the cut package belt


13


is moved sideways by the feed-in member


46


, where in the case of the package belt


13


or empty packages


13




c


in the unit of one-day doses, the cut package belt


13


is passed through as it is without being bundled by the bundling machine


47


; in the case of the stacked package belt


13


, the cut package belt


13


is once stopped at the bundling machine


47


, where the cut package belt


13


is bundled and then fed to the tray


9


via the distributing member


48


. In addition, in the distributing member


48


, for processing's sake, when empty packages


13




c


are conveyed up, the empty packages


13




c


are discarded to the dust box


63


via the opening


58


by rotating the distributing plate


59


.




Subsequently, the tray


9


is conveyed to the array ampoule dispensing station


5


, and further to the random ampoule dispensing station


6


. In this case also, based on the prescription information, the tray


9


is passed through as it is, or when ampoules


67


,


81


are fed, the tray


9


is stopped at a relevant unit.




After that, the tray


9


is conveyed to the label issuing station


7


. In the label issuing station


7


, the prescription paper


101


on which prescription information as to all the medicaments within the conveyed-up tray


9


has been printed, as well as a label


103


to be affixed to the surface to show the contents of the stored ampoules


67


are fed into the tray


9


.




Now that desired medicaments have been fed to the tray


9


in this way, this tray


9


is conveyed to the tray recovering station


2


, where the medicaments are transferred onto shelves of a sorting cart (e.g., medication storage cabinet marketed by Pyxis Co.) C by the arm


110


. In addition, this sorting cart C is movably set in the nurse station, and put into use for distribution to the patients in hospital when administration time has come.




<Medication Replenishment Operation>




Whereas the dispensing of medication is carried out as described above, the medication collecting system is enabled to detect the absence of the tablets


23


, the ampoules


67


,


81


, and to perform appropriate replenishment by checking these medicaments.




For this purpose, the tablet dispensing station


4


and the ampoule dispensing stations


5


,


6


are equipped, although not shown, with a touch panel to be controlled by a controller, a wireless barcode reader with a recharging cradle therefor, and a scale.




In the tablet dispensing station


4


, the tablet cassettes


20


are exchanged according to the flow charts of

FIGS. 19A and 19B

. That is, when specified tablets


23


have come out of stock so that an empty tablet cassette


20


is detected (step S


1


), the cylindrical drum


18


is rotated so that the empty tablet cassette


20


is moved to an interchangeable position, where its cassette number is notified, followed by a standby state (step S


2


). Also, a relevant medication profile is loaded from the database, and the current inventory count and expiration dates/lot numbers are displayed on the touch panel (step S


3


). Then, the operator obtains a wireless barcode scanner (step S


4


), reads the barcode of this tablet cassette


20


, verifying tablets


23


to be replenished (step S


5


). In this process, if the selected tablet cassette


20


is other than one containing the correct tablets


23


, the operator is informed of an error by the touch panel.




Subsequently, the operator places the empty tablet cassette


20


on the scale, where if the operator presses the “Tare” button on the touch panel (step S


6


), then the scale is initialized, prompting the operator to operate the bulk bottle for verification (step S


7


). If the verified bulk bottle is erroneous, the result is displayed on the touch panel, by which the operator is reported of it. If the verification result is correct, then the operator is prompted to pour in a desired quantity of medication into the scale. Then, if the operator has poured oral medication into the tablet cassette


20


on the scale (step S


8


), the scale counts the total medications poured into the tablet cassette


20


(step S


9


). In this case, if too much medication is poured in, a warning is presented on the touch panel.




Next, the operator operates a button on the touch panel, where if an end of the counting process is confirmed (step S


10


), then the final quantity is stored in the database (step S


11


). Subsequently, the operator is prompted to enter the manufacturer's lot number and expiration date according to the indication on the bulk bottle (step S


12


). Also, an alphanumeric keypad is displayed on the touch panel for the operator to key in values (step S


13


). If the operator has keyed in the manufacturer's lot number and expiration date and confirmed by touching an appropriate button on the touch panel (step S


14


), then the database is updated so that the lot number and expiration date are rewritten to the new ones (step S


15


).




After that, in order to verify a correct return place for the replaced tablet cassette


20


, the operator is prompted to scan the barcode of cassette location (step S


16


), and this is displayed on the touch panel. The operator sets a new tablet cassette


20


according to this instruction, where the operator scans the barcode of the cassette location provided just above the motor base


19


with no tablet cassette


20


set. If a barcode of a wrong position is scanned, this fact is displayed on the touch panel so that the operator is notified of it (step S


17


). With these steps of work completed, the operator sets the tablet cassette


20


to the motor base


19


in the corresponding position, and returns the wireless scanner to the original position (step S


18


).




It is noted that, also for the ampoule cassettes


69


and the ampoule containers


82


, the processes described above are carried out similarly according to the flow charts shown in

FIGS. 20A and 20B

.




<Consumables Management Operation>




Also, in this medication collecting system, even consumption state of consumable articles (printing ink, package belt and the like) in the units can be detected.




For example, the remaining quantity of the package belt


13


which is used in the tablet dispensing station


4


is calculated based on an initial length and a length required per package. Similarly, the remaining quantity of the band set to the bundling machine


47


which is used in the tablet dispensing station


4


is calculated based on an initial length and a band feed quantity. Further, remaining quantity of the prescription paper


101


which is used in the label issuing station


7


is calculated by subtracting the number of printed sheets from the initial setting number of sheets each time a printing process is performed. The remaining quantity of thermal transfer ink ribbon which is used in the label issuing station


7


is calculated based on an initial length and a consumption length (the consumption length for six-line printing is 3.5 mm).




Each time the consumption state of each consumable article is detected in this way, consumable article data is updated, where it is decided whether or not the article needs to be replaced. If it is decided that the article needs to be replaced, then an instruction that, for example, “Package paper will soon be out. Do you want to replenish?”, and “YES/NO” keys are displayed on the display as a replenishment operating screen. If the “YES” key is chosen, then replacement procedure for the relevant consumable article is displayed. Then, the article is replaced according to this procedure, and if the replacement is completed, a question, “Has replacement been completed?”, and “YES/NO” keys are automatically displayed. If the “YES” key is chosen, the replenishment operating screen is ended and consumable article data is updated, followed by a return to the normal screen.




<Automatic Bagging Station>




Whereas the tray recovering station


2


is provided in the above-described embodiment, an automatic bagging station shown in

FIG. 21

may be adopted instead (for more details, see Japanese Patent Applications HEI 10-203749, HEI 10-75813, etc.).




In this automatic bagging station, a sheet


112


wound around a roll


111


is formed into a bag shape by a sealing part


113


and cut into bags by a cutter


114


, and the bags are printed on the surfaces by a printer


115


and then conveyed to a medication feed part


116


. In the medication feed part


116


, with the bags opened, medicaments within the tray


9


are all put into the bags, and after sealing, the bags are accommodated in a large-size tray


117


provided below the medication feed part


116


. The large-size tray


117


is conveyed sideways by a conveyor


118


.




Although an embodiment of the present invention has been described above with reference to the accompanying drawings, modifications and changes apparent for those skilled in the art may be made in various ways. It is needless to say that these modifications and changes should be construed as being included in the present invention unless they depart from the spirit or scope of the invention.
