Description

  The present invention relates to a drug dispensing device that automatically dispenses various drugs such as ampoules, vials, blister packs, heat tablets, and box-contained ampoules according to a prescription.

  In the medicine dispensing apparatus, it is preferable that as many medicines as possible can be accommodated in a limited space, and there is a demand for high integration of medicine accommodation. In addition, there is a demand in use for reducing labor such as drug replenishment work as much as possible. Furthermore, there are various forms of medicines handled by the medicine dispensing device. Specifically, in addition to drugs in the form of normal ampoules and vials, the blister pack 1 shown in FIG. 23, the heat tablet 2 shown in FIG. 24, the box-housing ampule 3 shown in FIG. 25, and the synthetic resin shown in FIG. There is known a special form of medicine such as a multiple ampule 6 that is connected in series via a connecting portion 5 having a cut line (separation line 5a) that is easy to cut off the ampule 4. Furthermore, it is required to increase the processing speed, that is, to shorten the time from the input of prescription information to the completion of the payout process. In addition, it is also required to preferentially dispense the medicine stored earlier in time (so-called first-in first-out).

  Various types of medicine dispensing apparatuses have been proposed in response to the demand for high integration and handling. Regarding the demand for higher integration, for example, Patent Document 1 discloses a so-called aligned-type medicine dispensing apparatus that stores medicines in an aligned state. This medicine dispensing device includes a plurality of cassettes each containing a plurality of rows of medicines and stacked in a vertical direction, and an upper and lower for conveying medicines dispensed from a specific cassette according to a prescription. And a lifter that moves in the direction. Regarding the usage requirements, for example, Patent Document 2 discloses a so-called random-type medicine dispensing device that can accommodate medicines in a non-aligned state. Furthermore, a medicine dispensing device having both a random type and an ampoule type dispensing mechanism is also known.

  However, conventionally known medicine dispensing devices have limitations on the types of medicines that can be handled, and cannot dispense medicines sufficiently efficiently. For example, a medicine dispensing apparatus provided with both the random type and ampoule type dispensing mechanisms cannot handle the above-mentioned special form of medicine, and a special form medicine dispensing apparatus dedicated to the special form is necessary.

  Various proposals have been made for increasing the processing speed. For example, in Patent Document 1, the standby position of the lifter is set to a position corresponding to the lowermost shelf, and a medicine with a high dispensing frequency is accommodated in the lowermost shelf and the nearby shelf, thereby increasing the processing speed. It is described that it is planned.

However, the method described in Patent Document 1 is inconvenient in use because it is necessary for the user himself / herself to determine whether or not the medicine is frequently used, and the flexibility or flexibility of the medicine storage layout is greatly limited. Is done. Further, the method described in Patent Document 1 cannot meet the so-called first-in first-out request.

One of the containers has completed the required number of dispenses before the remaining containers. In particular, it is possible to further reduce the time required for payout by reallocation according to the third interrupt condition.

  It is preferable that the communication unit outputs the actual payout number when the payout for one prescription information is completed. For example, if the actual number of dispenses is transmitted to the host computer, the host computer side can grasp the actual number of dispenses, the type and number of drugs that have not been dispensed, and the like, making it easier to manage the drugs.

  As is clear from the above description, in the present invention, by incorporating a plurality of types of drug supply units into one apparatus, it is possible to handle various drugs including special forms of drugs in a single apparatus. In addition, it is possible to achieve both high accumulation of medicine storage and reduction of labor of medicine replenishment work. In addition, by appropriately executing drug search, allocation of dispensing, execution of dispensing, interruption processing, etc. by the control unit, it is possible to shorten the time required for dispensing drugs while ensuring flexibility in the layout of medicine storage. It is possible to achieve both paying out in order from the first supplemented drug.

However, since the lifter 41 extends above the common transport conveyor 100, the medicine dropped from the lifter 41 may be transported by the common transport conveyor 100 without passing through the transport conveyor 101.

  A transport conveyor (third transport path) 102 attached to the withdrawal mechanism 75 of the special drug medicine dispensing devices 14A and 14B is configured to transfer the medicine dispensed from the special drug medicine dispensing devices 14A and 14B to the back of the apparatus main body 11. The medicine is transported from the front side of the apparatus main body 11 to the back side (+ Y direction). Similarly, a transport conveyor (third transport path) 103 provided in the apparatus main body 11 transports the medicine from the front side to the back side of the apparatus main body 11. A transport conveyor (fourth transport path) 104 provided in the apparatus main body 11 is for transporting the medicine transported to the back side of the apparatus main body 11 by the transport conveyors 102 and 103 to the common transport conveyor 100. The medicine is transported from the left side to the right side (+ X direction) when the apparatus main body 11 is viewed from the front. The conveyor 103 is positioned below the conveyor 102 and above the conveyor 104. The downstream end of the transport conveyor 103 is arranged on the upstream side of the transport conveyor 104, and the downstream side merges with the common transport conveyor 100 on the opposite side of the transport conveyor 101. Further, a swinging member 105 for preventing the medicine from splashing is disposed on the downstream side of the transport conveyor 103. The upper end of the swing member 105 is pivotally supported with respect to the apparatus main body 11. When the medicine transported from the transport conveyor 102 splashes on the transport conveyor 103, it surely returns to the transport conveyor 103 by hitting the swing member 105. In addition, the medicines are aligned by the swing member 105 before being transported from the transport conveyor 103 to the transport conveyor 104. The medicines dispensed from the special medicine medicine dispensing devices 14 </ b> A and 14 </ b> B are conveyed to the stocker 15 via the conveyance conveyors 102, 103, and 104 and the common conveyance conveyor 100.

  The stocker 15 can be switched between a closed position indicated by a solid line in FIG. 2 and an open position indicated by an alternate long and short dash line in FIG. For example, when the medicine for one prescription is transported from the common transport path 100, the stocker 15 switches from the closed position to the open position, discharges the medicine to the tray 17, and then returns to the closed position.

  Since the medicine dispensing device 10 of this embodiment includes the medicine dispensing devices 14A and 14B for special medicines in addition to the aligned accommodation medicine dispensing device 12 and the random accommodation medicine dispensing device 13, various medicines including special forms of medicines are included. Can be handled. In addition, since the arrangement accommodation type medicine dispensing device 12 and the random accommodation type medicine dispensing device 13 are provided, it is possible to achieve both high accumulation of medicine accommodation and reduction of labor of medicine replenishment work.

  The lifter 41 is shared by the aligned accommodation type drug dispensing device 12 and the random accommodation type drug dispensing device 13. The medicine is finally sent to the stocker 15 by a single common conveyance conveyor 100. The common conveyance conveyor 100 is connected to the line-contained medicine dispensing device 12 and the random accommodation type via the conveyance conveyors 101 to 104. The medicines dispensed by the medicine dispensing device 13 and the special drug dispensing devices 14A and 14B are conveyed. Therefore, the internal space of the apparatus main body 11 can be effectively used and the apparatus can be reduced in size.

  Next, the dispensing control or dispensing operation in the random accommodation type medicine dispensing device 13 will be described in detail. Referring to FIG. 18, the controller (control unit) 111 of the aligned accommodation type medicine dispensing device 12 includes a communication unit 112, a storage unit 113, a timer 114, and a counter 115. The communication unit 112 receives from the host computer 116 prescription information including the type and number of medicines that are required to be dispensed. The storage unit 113 stores the type of medicine (medicine layout) stored in each medicine cassette 61 of each shelf 60. The counter 115 operates two types of counters i and t described later. The controller 111 also includes a search unit 117, an allocation processing unit 118, an interrupt processing unit 119, a lifter driving unit 120, and a payout driving unit 121. These cooperate with the communication part 112, the memory | storage part 113, the timer 114, the counter 115, the sensors 70 and 73, etc., and perform payout control.

  19 and 20 show the position of the payout control. In the processing of FIGS. 19 and 20, the rotational drive (dispensing operation) of the rotating body 69 and the drive of the lifter 41 are actually accompanied by steps S19-1, S19-9 to S19-11, and step S19-3. The processes other than these are executed as calculation processes in the controller 111.

  First, when the communication unit 112 receives prescription information from the host computer 116 in step S19-1, the counter i is incremented by 1 in step S19-2. The counter i indicates the number of shelves 60 from which the medicine search for each prescription information is started from the uppermost shelf 60 (hereinafter referred to as “shelf” as necessary), and the initial value is 0. It is. The maximum value imax of the counter i is determined by the total number of shelves 60 in the random accommodation type medicine dispensing device 13. For example, if there are 10 shelves 60, imax is 10. When incremented to the maximum value imax, the counter i is cleared to zero. Every time the prescription information is received, the counter i is incremented by 1 in step S19-1. In other words, the shelf on which the search unit 117 (to be described later) starts searching for drugs moves downward one by one.

  Next, in step S19-3, the current value of the counter i is substituted into the counter t. The counter t counts what number of shelves are being searched. Next, in step S19-4, prescription is completed, that is, dispensing based on prescription information (as will be described later, not only when all the required number of drugs included in the prescription information is dispensed, but also when there are undispensed drugs If not, the process proceeds to step S19-4. Next, when the counter t is smaller than the maximum value imax of the counter i in step S19-5, that is, when the search is not completed up to the lowest shelf 60, the process proceeds to step S19-6.

  In step S19-6, the search unit 117 searches the t-th shelf 60 corresponding to the current value of the counter t to see if there is a medicine cassette 61 that contains the medicine requested to be dispensed by prescription information. . Specifically, the search unit 117 compares the medicines stored in each medicine cassette 61 included in the t-th shelf 60 with the medicines to be dispensed, based on the medicine layout stored in the storage unit 113 described above. To do. When the search of the t-th shelf 60 is completed, the counter t is incremented by 1 in step S19-7, and then the process proceeds to step S19-8.

  In step S19-8, the allocation processing unit 118 executes the allocation process shown in FIG. First, in step S20-1, whether or not there are a plurality of medicine cassettes 61 containing the same medicine requested to be dispensed by prescription information in the shelf (t-th shelf) searched in step S19-6. Search for. This search is also executed based on the medicine layout stored in the storage unit 113 described above. If there are a plurality of medicine cassettes 61 in step S20-1, the process proceeds to step S20-2, and if not, the process proceeds to step S20-3. Therefore, step S20-2 is processing premised on the presence of a plurality of medicine cassettes 61 containing the same medicine on the shelf.

  In step S20-2, the state of the medicine cassette 61 and the cassette time stamp (container dispensing history) are determined. The state of the medicine cassette 61 includes a standby state (a state in which the medicine can be dispensed immediately), a preparation state (a state in preparation for dispensing), and a missing item or an unusable state. The cassette time stamp is the time when each medicine cassette 61 has dispensed medicine, and is stored in the storage unit 113. If there is a waiting medicine cassette 61, the medicine cassette 61 is set as the medicine cassette 61 to which dispensing is first assigned. At this time, if there are multiple standby statuses, the old one is prioritized based on the cassette time stamp (priority is given to the time when the last payout was made earlier) and the payout is assigned. . Also, when there is no medicine cassette 61 in the standby state and only the medicine cassette 61 in the ready state, the dispensing is preferentially assigned to the old one based on the cassette time stamp. Considering the state of the medicine cassette 61, the payout time is further shortened, and the first-in first-out can be surely performed by considering the cassette time stamp.

  In step S20-3, the presence / absence of the remaining allocation number (the presence / absence of a drug not assigned to the medicine cassette 61) and whether the lifter capacity is empty are checked. The presence or absence of the lifter capacity is determined based on lifter payout information described later. If there is a remaining allocation number and the lifter capacity is empty, one medicine dispensing is assigned to the medicine cassette 61 corresponding to step S20-4. In step S20-3, the allocation of dispensing to the medicine cassette 61 is repeated until the remaining number of allocations disappears in step S20-3 or the lifter capacity is full. By the processing in steps S20-3 and S20-4, the dispensing is evenly allocated to the plurality of medicine cassettes 61 while considering the capacity of the lifter 41. By assigning the payout while confirming the free space of the lifter capacity, the capacity of the lifter 41 can be effectively used up to that limit, and efficient payout becomes possible.

  If there is no remaining allocation in step S20-3 or if there is no free lifter capacity, the process proceeds to step S20-5. If there is no payout in step S20-6, that is, if no payout is assigned in step S20-4, the process returns to step S19-5 through step S20-7, and steps S19-5 to S19-8 are performed. The process is repeated. On the other hand, if there is a payout in step S20-5, that is, if a payout is assigned to at least one medicine cassette in step S20-4, the process proceeds to step S19-9 via step S20-6.

  In step S19-9, the lifter driving unit 120 moves the lifter 41 to the shelf 60 having the number of stages for which the allocation process has been completed in step S19-8. Here, it should be noted that the apparatus is actually driven for the first time in this step S19-9, and the processes before that are executed as internal processes of the controller 111. The processing prior to step S19-9 (steps S19-1 to S19-8) has a large number of steps on the flowchart, but is an internal processing of the controller 111, so the processing time is extremely short. Next, in step S <b> 19-10, the rotating body 69 of the corresponding medicine cassette 61 is rotationally driven based on a command from the dispensing drive unit 121, and the medicine is dispensed to the lifter 41. During this dispensing operation, the actual number of dispenses (the number actually dispensed to the lifter 41 for each drug requested to be dispensed by prescription information) is stored in the storage unit 113. A cassette time stamp is stored in the storage unit 113. Further, lifter dispensing information (the number of medicines dispensed to the lifter 41) is also stored in the storage unit 113.

  If the payout operation is completed for the shelf, the process returns to step S19-5, and the processes of steps S19-5 to S19-10 are repeated.

  When the interrupt condition in step S19-4 occurs during the payout operation in step S19-10, the interrupt processing unit 119 returns the process to step S19-8 to cause the allocation processing unit 118 to execute the payout allocation again. As an interruption condition, first, there is a case where no medicine is stored in the medicine cassette 61 to be dispensed (out of stock). Second, the medicine cassette 61 to be dispensed may not be dispensed (dispensing error). Third, one of the medicine cassettes 61 containing the same kind of medicines contained in the same shelf is the required number (number assigned in step S19-8) before the remaining other medicine cassettes 61. Have completed the payout.

  When the counter t exceeds imax in step S19-5, that is, when the search unit 117 has completed the drug search to the lowest shelf and the lifter 41 does not move further to the lower side, step S19-12. Migrate to In step S19-12, the value of the counter t is set to 1 (in the next step S19-6, the medicine cassette 61 on the first shelf 60 is searched). Next, after the lifter 41 moves to the lowermost position based on a command from the lifter driving unit 120 in step S19-3, the stored medicine is discharged to the stocker 15 via the transport conveyors 100 and 101, It returns to step S19-4.

  If prescription is completed in step S19-4, in step S19-11, the communication unit 112 transmits the number of payouts to the host computer 116, and the processing for one prescription is completed. For prescription completion, if all of the medicines that are requested to be dispensed with prescription information, the number of requested withdrawals and the actual number of withdrawals are equal (when dispensing according to the prescription information is actually completed), and dispensing with prescription information There is a case that any of the drugs that are required to be paid out cannot be paid out due to missing items. Therefore, the host computer 116 can ascertain the actual number of dispensed drugs, the type and number of drugs that have not been dispensed, and the management of the drugs becomes easy.

  The processing of FIGS. 19 and 20 will be further described based on a conceptualized example. FIG. 22 conceptually shows an example of the arrangement of the medicine cassettes 61 of the random-accommodating medicine dispensing device 13. In the figure, the vertical direction indicates the shelf and the lateral direction is the medicine cassette 61 with the same shelf. Indicates. Specifically, the number of shelves is five, and there are five drug cassettes 61 in each shelf. Moreover, the alphabet attached | subjected to each chemical | medical agent cassette 61 shows the kind of chemical | medical agent. Accordingly, the second medicine from the left in the second stage, the third cassette from the left in the second stage, and the second medicine cassette 61 from the left in the third stage contain the same medicine. In the following description, the medicine requested by the prescription information is “one medicine“ C ”, ten medicines“ G ”, and one medicine“ V ”” ”.

  When this prescription information is received (step S19-1), the first level is set as the search initial position (steps S19-1, S19-2), the prescription is not completed (step S19-4), and the counter t Since the value is 1, the first shelf 60 is searched (steps S19-5 and S19-6). The drug cassette 61 containing the drug “C” is in the third row from the left. After the counter t is set to 2 (step S19-7), the process proceeds to the allocation process (step S19-8). For the first stage, the process of step S20-1 is not established, and the remaining allocation number is 1 and the lifter capacity is vacant, so one payout is assigned to the third medicine cassette 61 from the left (step S20). -3, S20-4). When returning to step S20-3 again, the number of remaining allocations is already 0, so the process proceeds to step S19-9 via steps S20-5 and S20-6.

  The lifter 41 moves to a position corresponding to the first-stage shelf 60 (step S19-9), and the “C” medicine is dispensed to the lifter 41 from the third medicine cassette 61 from the left in the second stage ( Step S19-10).

  Next, the second shelf 60 is searched (steps S19-5 and S19-6). The “G” medicines that are required to be dispensed are stored in the second and third medicine cassettes 61 from the left.

  In the current allocation process, the determination in step S20-1 is established. If one of the second and third drug cassettes 61 is in the standby state and the other is in the ready state, the payout is assigned with priority over the standby state. For example, if the third medicine cassette 61 is in the standby state and the second medicine cassette 61 is in the ready state, the first, third, fifth, seventh, and ninth payouts are assigned to the third medicine cassette 61. The second, fourth, sixth, eighth and tenth dispenses are assigned to the second medicine cassette 61. In this way, by assigning the dispensing in consideration of the state of the medicine cassette 61, the time required for dispensing the medicine can be shortened.

  On the other hand, if both the second and third medicine cassettes 61 are in the standby state, the dispensing is alternately assigned with priority given to the oldest dispensing based on the cassette time stamp (steps S20-2 to S20-). 4). For example, if the time stamp of the second medicine cassette is older, the first, third, fifth, seventh, and ninth payouts are assigned to the second medicine cassette 61, and the third medicine cassette 61 is assigned. 2, 4, 6, 8, and 10th payouts are assigned. In this way, by assigning the payout in consideration of the history in which the medicine cassette 61 has executed the payout, so-called first-in first-out can be realized more reliably. However, in an actual dispensing operation (step S19-10) described later, a plurality of medicine cassettes 61 (in this example, the second and third medicine cassettes 61 from the left in the second stage) alternately perform dispensing. Instead, the plurality of medicine cassettes 61 perform the dispensing to the lifter 41 independently or simultaneously.

  After the allocation process, the lifter 41 actually moves to the second stage, and five “G” medicines are dispensed from the second and third medicine cassettes 61 from the left. At this time, for example, when the second medicine cassette 61 completes dispensing before the third medicine cassette 61, an interruption process occurs (step S19-14), and the second and third medicine cassettes 61 are dispensed again. Is allocated, and the payout is continued based on this. Such reallocation can further shorten the time required for payout. Further, for example, even if the second medicine cassette 61 is out of stock during delivery, an interruption process occurs (step S19-14), and the delivery is reassigned to the third medicine cassette 61. You can continue.

  When the dispensing of the “G” medicine is completed, the remaining medicine included in the prescription information is the “V” medicine. Since there are no medicine cassettes 61 containing “V” medicines in the third and fourth stages, the actual movement and dispensing of the lifter 19 are operated (steps) in the third and fourth stages. S19-9 and S19-10) are not performed and only the search is executed. Since there is a medicine cassette 61 containing “V” medicine third from the left in the fifth stage, the lifter 41 moves to the fifth stage, and the medicine V from the third medicine cassette 61 from the left It is paid out (steps S19-9, S19-10).

  When the process returns to step S19-5 after the medicine of “V” is dispensed, the value of the counter t is “6”, which is larger than “5” which is imax. Therefore, the medicine in the lifter 41 is stored in the stocker 15 in step S19-13. Discharged to the side. As described above, by discharging the lifter drug when the drug search is completed to the lowest level, the frequency of the lifting and lowering movement operation of the lifter 41 can be reduced, and the time required for the drug dispensing can be further shortened.

  FIG. 21 shows another example of payout control. In FIG. 21, the processes in steps S21-2 to S8 and steps S21-10 to S21 are the same as those in FIG. In step S21-9, the lifter time stamp (lifter movement history) is stored in the storage unit 113 during the lifter movement. The lifter time stamp is the time when the lifter 41 moves to each shelf. In step S21-2, the value of the shelf number of the shelf having the oldest lifter time stamp is set as the value of the counter i. Accordingly, the shelf where the search for each prescription information is started is the shelf where the lifter 41 has moved most recently. By such setting of the initial search position, the frequency of paying out on the upper shelf 60 and the lower shelf 60 is made uniform, and first-in first-out can be realized more reliably.

  The above control can also be applied to the line-accommodating medicine dispensing device 12. Further, if the same type of medicine is stored in the medicine cassette 61 of the aligned accommodation type medicine dispensing device 12 and the medicine cassette 61 of the random accommodation type medicine dispensing device 13, after the medicine is once dispensed from the aligned accommodation type medicine dispensing device 12. By returning the returned medicine to the random accommodation type medicine dispensing device 13, the returned medicine can be efficiently used for prescription.
