Regarding.

2. Description of the Related Art Conventionally, there has been known a medicine packaging device capable of individually packaging (dividing) a prescribed medicine for each dose. According to the medicine packaging device, only necessary medicines are divided according to the timing of taking medicine, such as when waking up, after breakfast, after lunch, after dinner, or before going to bed. It is also possible to print the patient's name and medication timing on individual packaging materials. This has the advantage of preventing forgetting to take medicine and taking the wrong medicine.

A drug packaging device generally includes a tray equipped with a plurality of masses for storing a drug by dividing it into single doses in accordance with a prescription, and feeding the drug from the masses to a packaging paper, and performing heat welding or the like. and a packaging unit that divides the medicine into single doses and seals and packages them.

There are various types and sizes of drugs handled by the drug packaging device. For this reason, for example, when a large number of tablets are prescribed for one dose or the size of the prescribed drug is large, one square of the tray can contain the drug for one dose. In some cases, there is no choice but to divide the medicine for one dose into multiple squares and store it.

In view of this situation, for example, in Patent Document 1 below, a desired plurality of divided masses for separately accommodating a drug is sent, while only one package of packaging material is sent and heated. An arrangement is disclosed in which the relationship between the rotational speed of the divider and the packaging speed of the packaging machine can be selected so that a sealed package is applied. That is, in this configuration, a plurality of squares of medicine can be accommodated in one packaging bag when necessary.

Further, Patent Document 2 below describes a first mode in which a drug contained in one drug containing chamber is packaged in one bag, and a mode in which a drug contained in a plurality of drug containing chambers is packaged. A medicine packaging device having a second mode of packaging a medicine in one bag is disclosed. That is, in this drug packaging device, by selecting the second mode, a plurality of squares of drugs can be accommodated in one packaging bag.

FIG. 4 is a diagram showing an example of a medicine package sheet 501 ejected from the packaging unit 5. As shown in FIG. As shown in FIG. 4, a medicine package sheet 501 is formed in a state in which medicine packages 502 each containing a medicine are arranged in a row. A perforation 503 is formed between the medicine packages 502, along which the medicine packages 502 can be separated individually. Although not shown in FIG. 4, it is possible to print various information such as the patient's name, facial photograph, drug name, usage/dosage, etc. on the surface of the medicine package 502 .

In the medicine packaging sheet 501, the packaging paper is folded in two along the center line parallel to the longitudinal direction, and in the packaging unit 5, the medicine is received while the packaging paper is sent out in the longitudinal direction, and then the packaging paper is folded in the longitudinal direction by heat welding. By forming transverse seals 504 extending along the longitudinal direction and longitudinal seals 505 extending transversely to the longitudinal direction, a drug envelope 502 is formed. A perforation 503 is formed on the vertical seal 505 . This step will be described in more detail later.

In the medicine packaging device 100, the order of the medicine packages 502 in the medicine package sheet 501 can be selected from two types of "continuous" and "repeated". When "Continuous" is selected, the medicine package sheet 501 is formed such that the medicine packages 502 with the same dosing time are consecutive. When "repeat" is selected, the medicine package sheet 501 is formed so that the medicine packages 502 for one day are arranged in order of dosing time. For example, when five days are prescribed for three types of dosing periods, "after breakfast", "after lunch", and "after dinner", when "continuous" is selected, the medicine package 502 for "after breakfast" is displayed. A medicine package sheet 501 is formed in a state in which five medicine packages 502 are consecutive, followed by five "after lunch" medicine packages 502, and then five "after dinner" medicine packages 502 are consecutive. On the other hand, when "repeat" is selected, the medicine package sheets 501 are formed in the order that the set of "after breakfast", "after lunch", and "after dinner" is repeated for five days. A pharmacist can specify from the input/output unit 1 whether to select “continuous” or “repeated”.

[Code reader 8]
The code reader 8 reads a code that identifies a drug, and is a JAN code, RSS code, or Code reading means for reading a QR code (registered trademark), for example, a mobile terminal such as a PDA. Note that the code reader 8 may be a conventionally known auxiliary device that is used by a pharmacist or the like when taking medicine out of a storage cabinet. The auxiliary device is used when a pharmacist or the like takes out a drug from a drug shelf according to a prescription and manually dispenses it. Check against data.

Information read by the code reader 8 is input from the code reader 8 to the input/output unit 1 by wireless communication. By using wireless communication in this manner, the code reader 8 can be freely carried to the medicine packaging device 100 or the medicine shelf. Of course, it is also conceivable that the code reader 8 is wired to the input/output unit 1 . When a plurality of drug packaging devices 100 are provided in a pharmacy, code readers 8 associated in advance with each of the drug packaging devices 100 are individually provided.

The code reader 8 can be configured with arbitrary hardware according to the type (standard) of the code to be read. For example, the code reading method is not limited to optical reading, and may be magnetic reading or electromagnetic reading. Also, the code reader 8 is not essential and can be omitted.

[Functions of control unit 2]
Next, functions of the control unit 2 that controls various operations in the medicine packaging device 100 will be described. As described above, the control section 2 includes the processor 21 and the storage section 22 . The processor 21 processes the data stored in the storage unit 22 and the input data according to the programs stored in the storage unit 22, thereby realizing the following various functions.

FIG. 5 is a functional block diagram of the control section 2. As shown in FIG. As shown in FIG. 5, the control unit 2 includes a divided data generation unit 211, a work instruction generation unit 212, an identification control unit 213, and a packaging control unit 214 as functional modules realized by the processor 21 and the storage unit 22. I have. It should be noted that these modules are called or generated when necessary and are not required to be resident.

FIG. 6 is a flowchart showing the procedure of processing by the control unit 2. As shown in FIG.

When the control unit 2 inputs drug prescription data based on a prescription (step S101), the control unit 2 acquires drug information included in the prescription data from the drug database stored in the storage unit 22 (step S102). Then, the divided data generation unit 211 of the control unit 2 determines how to divide the medicine included in the prescription data into a plurality of medicine packages (step S103). The divided data generator 211 further determines how the medicines assigned to the respective medicine packages are assigned to the plurality of cells 41 of the manual dispensing unit 4 (step S104).

Next, the work instruction generation unit 212 of the control unit 2 generates a work instruction screen for the pharmacist based on the result of the processing by the divided data generation unit 211, and displays it on the monitor of the input/output unit 1 (step S105). Further, the identification control section 213 of the control section 2 controls lighting of the LED 42 of the manual distributing unit 4 (step S106). The pharmacist performs the manual dispensing work while watching the work instruction screen displayed on the monitor and according to the lighting of the LED 42 of the manual dispensing unit 4 . When the manual distribution work is completed, the packaging control section 214 controls the packaging unit 5 to execute the packaging process (step S107).

By the above processing by the control unit 2, the medicine packaging device 100 can create the medicine package sheet 501 according to the prescription data.

[Processing of division data generation unit]
The division data generation unit 211 generates medicine division data representing the types and numbers of medicines to be put into each of the cells 41 of the manual dispensing unit 4 based on the prescription data. If there is only one kind of medicine to be injected, or if the kind of medicine to be injected is fixed, the medicine division data should represent only the number of tablets of the medicine to be injected. The procedure for generating drug division data will be specifically described below. FIG. 7 is an example of prescription data.

Here, it is assumed that prescription data as shown in FIG. 7 has been issued. Precisely, the prescription data includes "medicine name" and "single dose" shown in FIG. The divided data generator 211 acquires these data in step S101 of FIG. "Volume information", "1 tablet occupancy", and "drug occupancy" for each medicine are stored in the medicine database of the storage unit 22, and the divided data generation unit 211 generates the This is acquired from the storage unit 22 . In the example of FIG. 7, one dose includes 4 tablets of A drug, 20 tablets of B drug, 4 tablets of C drug, and 15 tablets of D drug. In this case, the number of tablets contained in one dose is so large that not all of the tablets can fit in the cell 41 of the manual dispensing unit 4 . Also, this single dose of tablet does not fit in one standard size package, so it is divided into multiple packages.

The volume information shown in FIG. 7 is the maximum number of tablets that can be accommodated in one medicine package of the medicine packaging device 100 . The 1-tablet occupancy rate is the reciprocal of the volume information expressed in %, and is the ratio of 1 tablet to the maximum number of tablets that can be accommodated in one medicine package. It should be noted that it is also possible to use the volume ratio of each medicine to the actual volume of one medicine package as the "per-tablet occupation ratio". The drug occupancy rate is the occupancy rate when one drug package contains the number of tablets for one dose of each drug, and is obtained by multiplying the one-time dose by the one-tablet occupancy rate.

The divided data generation unit 211 uses these data to perform the process of allocating one dose of medicine to a plurality of medicine packages in the above step S103 (step S103). FIG. 8 is a flow chart showing the detailed procedure of the processing in step S103.

The divided data generation unit 211 first calculates the number of medicine packages (number of divided packages) required to contain this one dose of medicine using the following formula (step S103a). Here, numbers after the decimal point are rounded up.
[Number of divided packages]=[Total chemical share]/[Allowable share] (Formula 1)
The total chemical occupancy rate is the sum of the chemical occupancy rates shown in FIG. Also, the allowable occupancy rate is a predetermined value, and is an allowable occupancy rate for one medicine package. In this example, the allowable occupancy rate is set to 100%, but it may be set to a value such as 90% or 80%, for example, in order to give some room to the medicine package.

In the example of FIG. 7, the total drug occupancy rate is 80.0+100.0+80.0+100.0=360.0%, and the allowable occupancy rate is 100%. .

Next, the divided data generation unit 211 calculates the target occupancy rate of the medicine package using the following formula (step S103b).
[Target occupancy] = [Total drug occupancy] ÷ [Number of divided packages] (Formula 2)

In this example, the total drug share is 360.0% and the number of divided packages is 4, so the target share is 90.0%.

Next, the divided data generation unit 211 allocates drugs to each of the four medicine packages based on the target occupancy rate. The divided data generator 211 first sets the variable n to "1" as an initial value (step S103c). Next, the divided data generation unit 211 selects one tablet having the largest one-tablet occupancy rate among the drugs included in the prescription data and not yet assigned to the medicine package, and selects the n-th drug. (step S103d), and the occupancy rate of the nth medicine package is calculated (step S103e). In the example of FIG. 7, first, drug A is selected as the drug with the largest one-tablet occupancy rate and assigned to the first drug package. FIG. 9(a) schematically shows a state in which four medicine A tablets are assigned to the first medicine package 502a of the four medicine packages by repeating steps S103d to S103e four times. It is a thing. At this stage, the occupation rate of the first medicine package 502a is 80.0%.

Next, as shown in (b) of FIG. 9, the divided data generation unit 211 allocates two tablets of D medicine to the first medicine package 502a. Here, the reason why two tablets of D drug are assigned without allocating the fifth tablet of A drug is as follows. When the fifth tablet of A medicine is assigned, the occupancy rate of the first medicine package 502a becomes 100%, which greatly exceeds the target occupancy rate of 90%. Therefore, the divided data generation unit 211 selects drug D, which has the next highest occupancy rate for one tablet after drug A, without allocating the fifth tablet of drug A, and assigns the first tablet of drug D to the first tablet. Assign to package 502a. At this point, the occupancy rate of the first medicine package 502a is 86.67%, which is 4 tablets of A drug (80%) and 1 tablet of D drug (6.67%). Since this occupancy rate has not reached the target occupancy rate of 90%, the divided data generation unit 211 allocates the second tablet of the D medicine to the first medicine package 502a. As a result, as shown in FIG. 9B, 4 tablets of A drug and 2 tablets of D drug are assigned to the first medicine package 502a, resulting in a occupancy rate of 93.4%. At this point, the occupation ratio has exceeded the target occupation ratio of 90% (YES in step S103f), so the process of the divided data generator 211 transitions to step S103g.

In step S103g, the divided data generator 211 adds 1 to the value of the variable n. If the value of the variable n does not exceed the number of split packages (NO in step S103h), the split data generation unit 211 updates the target occupation rate based on the following formula (step S103i).
[target occupancy] = ([total drug occupancy] - [allocated drug occupancy]) / [remaining number of packages] (Formula 3)

Here, the total drug occupancy is 360%, and the occupancy of the assigned drugs (that is, the occupancy of the first medicine package 502a) is 93.4%. The updated target occupancy rate for 502d is 88.8% (see (c) in FIG. 9).

After updating the target occupancy rate, the divided data generator 211 repeats the processing of steps S103d to S103i until all medicine packages are assigned. As a result, all medicines are finally assigned to the first to fourth medicine packages 502a to 502d, as shown in FIG. 9(d).

After the allocation of all medicine packages is completed, the divided data generator 211 determines whether or not the allocation of all medicines in the prescription data is completed (step S103j). Here, if there are medicines that have not been assigned yet (NO in step S103j), the number of divided packages is increased by 1, all assignment results so far are reset (step S103k), and the process returns to step S103b. , redo the assignment from the first cartridge.

In the above description, an example in which drugs are assigned in descending order of tablet occupation ratio has been described, but the order is not limited to this order, and drugs may be assigned in order of prescription data. Also, in the above description, the allocation is made so that the medicines are as evenly distributed as possible in all the medicine packages. However, without being limited to this, for the purpose of reducing the number of medicine packages as much as possible, the control may be such that as many medicines as possible are assigned to one medicine package as long as the occupancy rate does not exceed 100%.

As described above, the process of allocating medicines to medicine packages is performed, and when it is determined which medicine should be allocated how many tablets to which medicine packages, step S103 shown in FIG. 6 is completed, and the process proceeds to step S104. move on. In step S<b>104 , the divided data generation unit 211 performs processing for allocating the medicines allocated to the respective medicine packages to the cells 41 of the manual dispensing unit 4 .

FIG. 10 shows the internal processing flow of this step S104. Here, specific processing for allocating the medicines (4 tablets of A medicine and 2 tablets of D medicine) allocated to the first medicine package 502a to the cell 41 will be described. As shown in FIG. 11, the maximum number of tablets that can be accommodated in one cell 41 for each drug is stored in the drug database of the storage unit 22 as cell specific volume information. This maximum number of tablets may be the number of tablets obtained based on the actual volume of the cell 41, or may be a smaller volume than the actual volume of the cell 41 (for example, 50 %) may be defined as the number of tablets that can be accommodated. Note that the "one-tablet occupancy rate" here is the one-tablet occupancy rate for one cell, unlike the one-tablet occupancy rate for the medicine package shown in FIG. That is, the "one tablet occupancy rate" here is the reciprocal of the cell specific volume information expressed in %, and is the ratio of one tablet to the maximum number of tablets that can be accommodated in one cell 41 . It should be noted that it is also possible to use the volume ratio of each medicine to the actual volume of one cell 41 as the “per-tablet occupancy ratio”.

As shown in FIG. 10, the divided data generator 211 first calculates the number of cells 41 required to contain the medicine in the first medicine package 502a (required number of cells) using the following formula: Calculate (step S104a). Here, numbers after the decimal point are rounded up.
[Necessary number of cells]=[Total drug occupancy]/[Allowable occupancy] (Formula 4)
The total chemical occupancy rate is the sum of the chemical occupancy rates shown in FIG. Also, the allowable occupancy rate is a predetermined value, and is the allowable occupancy rate for one cell 41 . In this example, the allowable occupancy rate is set to 100%, but it may be set to a value such as 90%, 80%, or 50% in order to provide some leeway.

In the example of FIG. 11, the total drug occupancy rate is 160.0+26.6=186.6%, and the allowable occupancy rate is 100%.

Next, the divided data generator 211 calculates the target occupancy rate of the cell 41 using the following formula (step S104b).
[target occupancy]=[total drug occupancy]/[necessary number of cells] (Formula 5)

In this example, the total drug occupancy is 186.6% and the required number of cells is 2, so the target occupancy is 93.3%.

Next, the divided data generator 211 determines drug allocation to two cells (hereinafter referred to as “first cell” and “second cell”) based on the target occupancy rate. The divided data generator 211 first sets the variable n to "1" as an initial value (step S104c). Next, the divided data generation unit 211 selects one tablet of the medicine having the largest one-tablet occupancy rate among the medicines assigned to the first medicine package 502a and not yet assigned to cells. and assigns it to the n-th (initial n=1) cell (step S104d), and calculates the occupancy rate of the n-th cell (step S104e). In the example of FIG. 11, first, drug A is selected as the drug with the highest one-tablet occupancy rate and assigned to the first cell. FIG. 12(a) schematically shows a state in which two tablets of A drug are assigned to the first cell by repeating steps S104d to S104e twice. At this stage, the occupancy of the first cell is 80.0%.

Next, as shown in (b) of FIG. 12, the divided data generation unit 211 allocates one tablet of D drug to the first cell. Here, the reason for allocating one tablet of drug D without allocating the third tablet of drug A is as follows. As shown in FIG. 11, when the third tablet of drug A with a 1-tablet occupancy rate of 40% is assigned to the first cell, the occupancy rate of the first cell is 120%, which is 90% of the target occupancy rate and acceptable. Over 100% occupancy. Therefore, the divided data generation unit 211 selects drug D, which has the next highest occupancy rate for one tablet after drug A, without allocating the third tablet of drug A, and assigns the first tablet of drug D to the first tablet. Assign to cell. At this point, the occupancy rate of the first cell is 93.3%, which is 2 tablets of A drug (80%) plus 1 tablet of D drug (13.3%). Since this occupancy rate has reached the target occupancy rate (YES in step S104f), the processing of the divided data generation unit 211 transitions to step S104g.

In step S104g, the divided data generator 211 adds 1 to the value of the variable n. If the value of the variable n does not exceed the required number of cells (NO in step S104h), the divided data generator 211 updates the target occupancy based on the following formula (step S104i).
[target occupancy] = ([total drug occupancy] - [allocated drug occupancy]) / [remaining number of cells] (Formula 6)

Here, the total drug occupancy is 186.6% and the occupancy of the assigned drugs (ie, the first cell occupancy) is 93.4%, so the updated target occupancy is 93.4%. 3% (see (c) of FIG. 12).

After updating the target occupancy rate, the divided data generation unit 211 repeats the processing of steps S104d to S104i until allocation is completed for all cells. This finally allocates all drugs to the first cell and the second cell, as shown in FIG. 12(d).

After all the cells have been assigned, the divided data generator 211 determines whether all the medicines assigned to the target medicine package have been assigned to the cells (step S104j). ). Here, if there are medicines that have not been allocated yet (NO in step S104j), the number of necessary cells is increased by 1, all allocation results so far are reset (step S104k), and the process returns to step S104b. , redo the assignment from the first cell.

By performing the above processing for all medicine packages, it is determined where and how many tablets of the medicine assigned to each medicine package should be put into each of the plurality of cells 41 of the manual dispensing unit 4 .

As described above, when the process of allocating medicines to cells is performed and it is determined which medicines should be put into which cells and how many tablets each, step S104 shown in FIG. 6 is completed, and the process proceeds to step S105.

[Processing of Work Instruction Generation Unit 212]
The work instruction generation unit 212 generates a work instruction screen including information on the type of medicine to be put into each cell 41 of the manual dispensing unit 4 and the number of tablets according to the allocation result determined in step S104.

13 and 14 show examples of work instruction screens generated by the work instruction generation unit 212 and displayed on the monitor of the input/output unit 1. FIG. The work instruction screen shown in FIG. 13 has, in the upper right part of the screen, a drug specification section 1301 in which the name of the drug to be hand-dispensed is displayed.

The pharmacist takes out the medicine to be manually dispensed from the storehouse or the like in advance. When a pharmacist reads a code such as a bar code attached to a drug container or the like with a code reader 8 , the code information read by the code reader 8 is sent to the control section 2 . Based on the data read here, the control unit 2 determines whether or not the medicine in the container read by the code reader 8 matches any of the medicines in the prescription data. When it is confirmed that they match, the control unit 2 displays the name of the drug in the drug specification section 1301 of the manual distributing work instruction screen as shown in FIG.

Then, when the pharmacist selects the drug line 1302 in the drug specification section 1301, the work instruction generation section 212 generates a cell list as shown in FIG. 14 and displays it on the monitor.

This cell list table is based on the data generated by the allocation processing of the divided data generation unit 211 as described above, and indicates which medicines and how many tablets are put into which cells of the manual dispensing unit 4. . That is, the cell list shown in FIG. 14 has the same number of rows and columns as the cells 41 of the manual distributing unit 4 . In the squares corresponding to each cell 41, the number of medicine tablets to be put into the cell is indicated by a number. The pharmacist can put the correct number of drugs into each of the cells 41 by manually distributing the drugs while looking at the cell list.

The design of the cell list shown in FIG. 14 is merely an example, and the design is not limited to this. In the medicine packaging device 100, the medicine packaging sheet 501 is set to a "continuous mode" in which medicine packages with the same dosing period are consecutively arranged, and one day's worth of medicine packages are consecutively arranged in the order of the dosing period and repeated for several days. It is possible to select a "repeat mode" to The work instruction generation unit 212 can switch the display mode of the cell list depending on which mode is selected.

Further, when the number of cells required for packaging all the medicines exceeds the total number of cells 41 in the manual distribution unit 4, the work instruction generation unit 212 divides the manual distribution work into multiple times. , to generate the work instruction screen. For example, in the example shown in FIG. 3, the number of cells 41 is 48, but if the required number of cells exceeds 48, on the first work instruction screen, the manual work for 48 or less cells 41 is performed. let it happen Then, when the first manual distribution work is completed, the control section 2 feeds the medicine put into the manual distribution unit 4 to the packaging unit 5 to perform the packaging process. When the packing process of the medicine put in the first manual distribution work is completed, the work instruction generation unit 212 generates a work instruction screen for instructing the second manual distribution work, and displays it on the monitor of the input/output unit 1. Let As described above, in the case of a configuration in which a delivery mechanism is provided below the manual distribution unit 4, and when the start button for the sachet-and-packaging process is pressed, the medicines in the manual distribution unit 4 are dropped into the delivery mechanism all at once. can perform the packaging process of the medicine manually distributed in the first manual distribution work and the second manual distribution work in parallel.

As described above, when the manual distribution work is divided into a plurality of times, the work instruction generation unit 212 does not divide the manual distribution of the medicine to be put into one medicine package into two manual distribution tasks. Generate a work instruction screen as follows. A specific example of this is shown in FIG. In the example of FIG. 15, the number of cells required to accommodate a single dose upon waking is 6, the number of cells required to accommodate a single dose after breakfast is 5, and the number of cells required to accommodate a single dose after breakfast is 1. 4 cells required to accommodate a single dose, 3 cells required to accommodate a single post-dinner dose, and a single pre-sleep dose required Prescription data for 3 days with 2 cells is input. In other words, in this example, for example, the medicine for taking when waking up is divided into 6 cells, and the medicine for 6 cells is enclosed in one medicine package during the packaging process.

In FIG. 15, the rightmost column shows the total number of cells required when the chemicals are supplied to the manual dispensing unit 4 in order from the top row. Assuming that the number of cells in the manual distributing unit 4 is 48, as shown in FIG. Create a work instruction screen assuming that it will be input in the first manual work. That is, only 46 of the 48 cells 41 are used in the first manual distributing work. Then, the work instruction generation unit 212 generates a work instruction screen so that the prescription after breakfast on the third day is input in the second manual distributing work.

In other words, assuming that all 48 cells 41 are used in the first manual hand-distribution work, the dosage after breakfast on the third day (5 cells) is equivalent to the first hand-distribution work (2 cells) and 2 cells. It will be divided into the second manual scattering work (3 cells). In this case, the drug for the dose (5 cells) after breakfast on the 3rd day starts to be divided and packaged after the first manual distribution work is completed, but until the second manual distribution work is completed. , the packaging process is interrupted in the middle of packaging. It is undesirable for such interruptions to occur. For this reason, in the present embodiment, when the medicine enclosed in one medicine package extends over a plurality of cells, the work instructions are generated so that the plurality of cells are not separated into two manual distributing works. A unit 212 adjusts the number of target cells for manual work and generates a work instruction screen.

In this way, when the manual work is divided into multiple times, a display (text display, etc.) that shows how many times the current manual work is done is displayed on the work instruction screen. It is desirable to Further, in the example of FIG. 15, the first manual distributing work is performed until the time of waking up on the third day. Also good.

In this example, the work instruction generation unit 212 is assumed to generate a work instruction screen to be displayed on the monitor. However, the method of providing work instructions is not limited to this. For example, the configuration may be such that voice guidance is provided.

[Identification control unit 213]
In the first embodiment, the identification control unit 213 controls the lighting of the LEDs 42 provided next to the cells 41 in the manual distributing unit 4, thereby identifying which cell the medicine should be put into. and

In the medicine packaging device 100, when the manual distribution work is performed, the input/output unit 1 and the manual distribution unit 4 are interlocked to display the manual distribution work instruction screen on the monitor of the input/output unit 1, In the manual distributing unit 4, the LED 42 of the cell 41 into which the medicine should be put is lit.

That is, as described above, when the pharmacist selects the row 1302 of the drug to be dispensed manually in the drug specification section 1301, the LED 42 of the cell 41 into which the drug is to be added lights up, and the LEDs of the other cells 41 turn on. It turns off. This prevents the pharmacist from putting medicine into the wrong cell.

If the medicine to be enclosed in one medicine package extends over a plurality of cells 41, the LED 42 may emit light so that the boundary cell position of each medicine package can be identified. For example, when the drug enclosed in one drug package is divided into three cells 41, the LEDs 42 of the 3rd cell, 6th cell, 9th cell, . . . are lit or blinked. You can Further, if each LED 42 is configured to emit light of multiple colors, more complicated identification control becomes possible. For example, when the medicine enclosed in one medicine package is divided into three cells 41, the LED 42 may emit different colors every third cell or every third cell. In this way, by controlling the light emission of the LED 42 so that the position of the cell at the boundary of each medicine package can be seen, the boundary between the cells of each medicine package can be easily recognized, and the accident of putting medicine into the wrong cell can be prevented. It can be prevented.

Here, a configuration example in which a cell into which a drug is to be injected can be identified by lighting an LED has been described, but identification means other than the LED may be used. For example, project mapping may be used to make it possible to identify the cells into which drugs should be injected and to project the number of drugs to be injected.

[Packaging control unit 214]
When the manual distribution work for the manual distribution unit 4 and the confirmation work for checking whether the medicine is correctly put in are completed and the packing start button is pressed, the cells 41 ₀₁ to 41 ₄₈ of the manual distribution unit 4 are executed as described above. By sequentially opening the bottom surface of the cell 41 ₀₁ to 41 ₄₈ , the drugs in the cells 41 01 to 41 48 are sequentially delivered to the packaging unit 5 and packaged in the packaging unit 5 . In addition, as described above, the opening order of the cells can be arbitrarily set.

The packaging unit 5, as shown in FIG. 16, includes a pair of horizontal rollers 54 (first sealing mechanism) and a pair of vertical rollers 55 (second sealing mechanism). These pair of rollers are equipped with a heater, and sandwich the packing paper 500 to heat-seal them. The horizontal rollers 54 form horizontal seals 504 parallel to the feeding direction of the packaging paper 500 while feeding the packaging paper in a fixed direction. The vertical rollers 55 form vertical seals 505 in a direction crossing the feeding direction of the packaging paper.

The horizontal rollers 54 and the vertical rollers 55 are formed to rotate coaxially. 17 is a schematic cross-sectional view of the vertical roller 55 when viewed in a cross section perpendicular to the rotation axis X. FIG. Note that FIG. 17 is a schematic diagram and does not accurately represent the configuration of the vertical rollers 55 . As shown in FIG. 17, the vertical roller 55 has a substantially rectangular cross section perpendicular to the rotation axis X, and has heaters 55h on both short sides of the cross section.

As shown in FIG. 17(a), the vertical rollers 55 include vertical rollers 55a and vertical rollers 55b. The vertical roller 55a rotates about the rotation axis X counterclockwise. The vertical roller 55b rotates around the rotation axis X clockwise. When the vertical rollers 55a and 55b are rotated 90 degrees from the state shown in FIG. 17(a), the vertical rollers 55a and 55b face each other as shown in FIG. 17(b). Thermally weld. Here, the configuration in which the vertical seal is formed each time the vertical roller 55 rotates 180 degrees is exemplified, but the configuration may be such that the vertical seal is formed only once in every 360-degree rotation.

As shown in FIG. 16, the horizontal roller 54 is always in contact with the packaging paper 500, and has a heater (not shown) on the entire circumference of the surface in contact with the packaging paper 500. As shown in FIG. Therefore, the horizontal rollers 54 continuously form the horizontal seals 504 along the feeding direction of the packaging paper while constantly contacting the packaging paper 500 while the packaging paper is being fed. On the other hand, the vertical roller 55 contacts the packaging paper 500 each time it rotates about the rotation axis X by 180 degrees, and forms vertical seals 505 at predetermined intervals.

With such a configuration, the packaging unit 5 can form the medicine package 502 by forming the horizontal seal 504 and the vertical seal 505 by heat welding.

Although the horizontal roller 54 and the vertical roller 55 have coaxial rotation axes, their rotation speeds can be controlled separately. Therefore, for example, by stopping the vertical roller 55 and rotating only the horizontal roller 54, only the horizontal seal 504 can be formed over a desired length. In other words, by adjusting the timing of moving the vertical rollers 55, it is possible to vary the bag length in the horizontal direction (in the feeding direction of the packaging paper).

Furthermore, when packaging a plurality of cells of medicine in one medicine package, by finely controlling the feeding amount of the horizontal roller 54 in accordance with the timing of feeding the medicine from the cell to the packaging paper, the medicine package can be distributed in the horizontal direction ( The medicine can be well dispersed in the feeding direction of the packaging paper).

FIG. 18 shows the feeding amount of the roller (horizontal roller 54) and the feeding amount when enclosing 1 to 6 cells of medicine in one medicine package for each case of setting the bag length to 80 mm, 90 mm, 100 mm, and 110 mm. An example of halfway stop timing is shown. However, the timing shown in FIG. 18 is merely an example, and the number of stops and the stop position can be arbitrarily set. In addition, the numerical value described in the column of "Roller feed amount and halfway stop timing" in the figure represents the distance from the last formed vertical sticker 505 (distance in the feeding direction of the packaging paper).

For example, when the bag length is 80 mm and one cell of medicine is enclosed in one medicine package, the horizontal roller 54 is stopped when the packaging paper is fed by 39 mm from the vertical seal 505 formed last. Then, when the horizontal roller 54 stops, the medicine is put into the packaging paper from the cell. After that, by rotating the horizontal roller 54 and the vertical roller 55, the next vertical seal 505 is formed at a distance of 80 mm from the last formed vertical seal 505. As shown in FIG. As a result, one 80 mm medicine package containing one cell of medicine is formed.

Also, when the bag length is 80 mm and three cells of medicine are enclosed in one medicine package, the horizontal roller 54 is stopped when the packaging paper is fed by 39 mm from the vertical seal 505 formed last. Then, when the horizontal rollers 54 have stopped, the medicine is put into the packaging paper from a total of two cells, the first cell and the second cell. Next, only the horizontal roller 54 is rotated, and when the packaging paper is fed by 55 mm from the finally formed vertical seal 505, the horizontal roller 54 is stopped, and the medicine in the third cell is put into the packaging paper. . After that, by rotating the horizontal roller 54 and the vertical roller 55, the next vertical seal 505 is formed at a distance of 80 mm from the last formed vertical seal 505. As shown in FIG. This forms one 80 mm drug package containing three cells of drug. In addition, since the medicine is injected in two locations, one at a distance of 39 mm from the last formed vertical seal 505 and the other at a distance of 55 mm, the medicine is injected in two locations, compared to the case where the medicine for three cells is collectively injected at one location. , the bending of the packaging paper is small. As a result, problems such as wrinkling of the medicine package and misalignment of the seam of the packaging paper at the portion forming the horizontal seal 504 can be suppressed, and the packaging paper can be sealed neatly. In this case, the medicine is introduced after stopping the rotation of the horizontal roller 54, but the medicine can be injected from the cell 41 of the manual dispensing unit 4 while the horizontal roller 54 is rotating.

[Modification]
Although the embodiments of the present invention have been specifically described above, the embodiments of the present invention are not limited to the aspects described above, and various modifications are possible.

For example, in the above description, the drug packaging device 100 provided with only the manual dispensing unit 4 was illustrated, but the present invention can also be applied to a drug packaging device further provided with a tablet cassette or a powder cassette. . Also, for a medicine packaging device for a so-called blister pack, in which the medicine tray is set on the manual dispensing unit 4, the medicine is put in, and the whole surface of the medicine tray is sealed when the injection is completed, without the packaging unit 5. can also apply the present invention. For example, the powder medicine packaging machine disclosed in Japanese Patent Application No. 2010-504097 (International Publication No. 2010/032418) previously filed by the present applicant, and Japanese Patent Application No. 2010-504097 (International Publication No. 2010/032418). and the blister packaging machine disclosed in PCT/JP2018/18110 previously filed by the present applicant can be applied to the present invention.

Also, in the description of the processing of step S104 in FIG. 6, an example of allocating a plurality of types of drugs to one cell was described, but only one type of drug may be assigned to one cell. By making such allocation, it is possible to effectively prevent miscounting of the medicines in the cells, thereby preventing dispensing accidents.

Further, in the above-described embodiment, the configuration in which the packaging unit 5 thermally welds the packaging paper by the heat roller to form the medicine package has been exemplified. However, the configuration example of the packaging unit is not limited to this, and any packaging device can be used. For example, the drug packaging device disclosed in Japanese Patent Application No. 2003-401593 (Japanese Patent Application Laid-Open No. 2005-162240) previously filed by the present applicant can be applied to the packaging unit of the present invention.

The LED 42 of the manual dispensing unit 4 can have the following functions in addition to the function of allowing the pharmacist to identify the cell into which the medicine should be put, as described above.

For example, when some kind of abnormality or operation interruption due to an error occurs during the operation of the medicine packaging device 100, the LED 42 emits light or flashes in a special pattern so that the operator can be at a distance, Even if there is a lot of noise in the surrounding environment, this can be notified to the operator. In addition, it is also preferable to vary the light emission pattern of the LED 42 according to the event. For example, if some error occurs, all the LEDs 42 of the manual distributing unit 4 are flashed in red, and if some warning occurs, all the LEDs 42 of the manual distributing unit 4 are flashed in yellow. It is conceivable that

Further, the manual dispensing unit 4 is provided on the upper surface of the medicine packaging device 100, and even if the LED 42 blinks, it may be difficult for an operator who is far away to visually recognize it. Therefore, if a reflector or the like is attached to the housing of the drug packaging device 100 to diffuse the light from the LEDs 42 in the horizontal direction, the lighting state of the LEDs can be easily recognized even from a distance.

Further, in the above description, the prescription data is input and the divided data generation section 211 of the control section 2 determines which drug should be put into which cell. However, the pharmacist may set and change the number of medicine packages and the number of cells per medicine package from the body panel 6 without using the divided data generation section 211 of the control section 2 .

For example, when three medicine packages are to be hand-dispersed and one cell corresponds to one medicine package, the LEDs 42 for three cells are lit. In addition, if the pharmacist can change the number of medicine packages from the body panel 6, and the number of medicine packages is changed from 3 to 2, one of the LEDs 42 lit for 3 cells is turned off, The LEDs 42 for two cells are turned on.

Further, for example, when the medicine to be put into one medicine package is divided into 5 cells and manually distributed, when the pharmacist changes the 5 cells to 6 cells from the main body panel 6, the LED 42 is also changed. For example, if the boundary between medicine packages was displayed by lighting the LEDs 42 every five cells before the change, the lighting interval is changed every six cells. In this way, by changing the display state of the LED according to the change of the setting, it becomes possible to distinguish the number of medicine packages and the division of the scattering position for each medicine package at a glance.

Furthermore, the lighting state of the LED 42 when the number of medicine packages and the number of cells per medicine package are set from the main body panel 6 is the lighting state of the LED 42 according to the determination by the divided data generation unit 211 of the control unit 2. It is also desirable to make them different. Here, "differentiating the lighting state" includes, for example, differentiating the emission color of the LED. By making the lighting state different in this way, it becomes easy to distinguish whether the manual distributing instruction automatically set based on the prescription data is being followed or the manual distributing procedure set by the pharmacist from the body panel 6 is being followed.

Further, in the above-described embodiment, an example in which work instructions are given to the pharmacist by both the display of the work instruction screen on the monitor of the input/output unit 1 and the lighting of the LED 42 in the manual dispensing unit 4 has been described. However, there is a configuration in which the instruction by the LED or the like in the manual distribution unit is omitted and the work instruction is given only by displaying the work instruction screen on the monitor, or the work instruction in the input/output unit 1 is omitted and the LED in the manual distribution unit 4 is turned on. A configuration that only performs the above is also included in the embodiments of the present invention.

Further, in the above-described embodiment, a configuration is exemplified in which the rotational speeds of the horizontal rollers 54 and the vertical rollers 55 can be controlled separately. According to this configuration, as illustrated in FIG. 18, medicine packages having a plurality of types of bag lengths can be produced. However, if the bag length is constant, the horizontal rollers 54 and the vertical rollers 55 may be configured to rotate integrally.

Furthermore, in the above embodiment, the drug packaging device 100 including both the manual distribution unit 4 and the packaging unit 5 is illustrated. However, the manual distribution work and the packaging process may be performed by separate devices. For example, in a medicine distribution device in which the packaging unit 5 is omitted from the medicine packaging device 100, only manual dispensing work is performed, and the cell trays into which the medicines are put by manual distribution are distributed by the device provided with the packaging unit 5. A mechanism for hull processing is also included in one embodiment of the present invention.
