The packaging material 40 containing the drug is sent out to a reservoir inside or outside the drug packaging device 1 .

In the medicine packaging device 1, a discharge standby section 23 is provided at the boundary between the portion for weighing and the portion for packaging. An intermediate container 91 containing a medicine or an external weighing container 92 can be put on standby in the discharge waiting section 23 as necessary.

The cleaning section 38 can clean the intermediate container 91 or the external weighing container 92 . Cleaning is accomplished, for example, by applying compressed air to the inner surface of the intermediate container 91 or the outer metering container 92 to remove residual medicament. However, cleaning may be performed by other means such as a brush.

In the medicine packaging device 1 , a cleaning waiting section 37 is provided near the cleaning section 38 . In the cleaning waiting section 37, the intermediate container 91 or the external weighing container 92 before being cleaned can be put on standby as needed.

The discharge standby section 23 and the cleaning standby section 37 can be configured as, for example, plate-like members on which containers can be placed, but are not limited to this.

The control unit 50 can control each unit of the medicine packaging device 1 (specifically, the weighing unit 30, the packaging unit 33, etc.) based on the dispensing data. In this embodiment, the control unit 50 is configured as a part of the medicine packaging device 1, but it is part of a dispensing equipment control device that controls the medicine packaging device 1 and other dispensing equipment such as the medicine packaging device 95. It may be configured as a part.

Specifically, the control unit 50 is configured as a known computer, and includes an arithmetic device such as a CPU, a storage device such as a flash memory or hard disk, and an input/output unit for communicating with the outside. Various programs and setting values are stored in the storage device. The computing device reads out various programs from the storage device, and based on the detection values of the sensors provided in each part of the medicine packaging device 1 and the various setting values stored in the storage device, the medicine packaging device 1 is operated. Controls the operation of each part. The control unit 50 operates as the storage unit 61, the weighing selection unit 62, the excipient selection unit 63, the correspondence selection unit 64, and the guide unit 65 shown in FIG. The packaging device 1 can be operated.

The storage unit 61 can store dispensing data input from the outside as described above. In addition, the storage unit 61 stores the stored drug information of the drug container 15 read by the first information processing unit 16 as arrangement information of the drug container 15 arranged in the drug packaging device 1 . In addition, the storage unit 61 can store various setting values necessary for operation. The set values will be described in detail below.

For example, as an ability of the packaging unit 33, there is a lower limit to the weight of medicine that can be packaged (the weight of the total dose), and medicines smaller than that cannot be packaged. The storage unit 61 stores a value based on this lower limit value as the first setting value. Similarly, regarding the packaging unit 33, there is a lower limit for the weight of the medicine that can be packaged (weight for one dose). The storage unit 61 stores a value based on this lower limit value as the second set value.

In addition, as the capability of the weighing unit 30, there is a lower limit to the weight of the drug that can be weighed. The storage unit 61 stores a value based on this lower limit value as the third set value.

FIG. 1 shows an example in which a plurality of drug packaging devices 95 are installed in addition to the device itself. Another drug packaging device 95 can package drugs in place of the drug packaging device 1 . The storage unit 61 stores, as a fourth setting value, a value based on the lower limit of the weight of all the medicines that can be packaged by the medicine packaging device 95 for the other medicine packaging device 95, and the medicine packaging device 95 can pack the medicine. A value based on the lower limit of the weight of one dose of the drug is stored as the fifth set value. Since the packaging capabilities of the other medicine packaging devices 95 may differ, the storage unit 61 stores the fourth setting value and the fifth setting value for each of the other medicine packaging devices 95 .

In the present embodiment, the first set value is set to a value equal to the lower limit of the weight of all doses of medicine that can be packaged in the packaging section 33 . The second set value is set to a value equal to the lower limit of the weight of one dose of medicine that can be packaged in the packaging unit 33 . The third set value is set to a value equal to the lower limit of the weight of the medicine that can be weighed by the weighing unit 30 . The fourth set value is set to a value equal to the lower limit of the weight of all doses that can be packaged by the other medicine packaging device 95 . The fifth set value is set to a value equal to the lower limit of the weight of one dose that can be packaged by another medicine packaging device 95 . Note that each set value may be set to a value according to the type of drug, for example. Further, the first set value, the second set value, the fourth set value, or the fifth set value are arbitrarily set by the operator based on the internal regulations of the hospital or pharmacy where the drug packaging device 1 is installed. good too. In this case, the first set value and the second set value can be set on the condition that the weight of the medicine that can be packaged in the packaging section 33 is equal to or greater than the lower limit.

In addition, the storage unit 61 stores various data such as master information about drugs. This master information includes, for example, drug code, drug name, JAN code (or RSS), drug bottle (drug container) code, classification (dosage form: powdered drug, tablet, topical drug, etc.), specific gravity, drug type (ordinary drug , poisonous drugs, narcotics, powerful drugs, antipsychotics, therapeutic drugs, etc.), compounding changes, precautions, regular doses, information on prohibition of simultaneous use, etc.

The storage unit 61 can also store container-specific information (container identification number, container type, etc.) as container master information.

When at least one of the medicines indicated by the medicine information cannot be packaged due to the capacity of the packaging unit 33 of the device itself, the weighing selection unit 62 selects the medicine to be weighed by the weighing unit 30 of the device itself. The operator can select whether or not to perform the weighing operation by the weighing unit 30 for the medicine that can be taken. Although there are various configurations for realizing the selection, for example, the weighing selection unit 62 may display options (for example, buttons for execution/non-execution) on the display unit 21 and allow the operator to select using the operation unit 22. Conceivable.

The excipient selection unit 63 selects an excipient when at least one of the medicines indicated by the medicine information cannot be packaged due to the capacity of the own packaging unit 33 or the capacity of another medicine packaging device 95 . The operator can choose whether to perform a weighing action or a weighing and dispensing action for the drug. Although there are various configurations for realizing the selection, it is conceivable that the excipient selection unit 63 causes the display unit 21 to display options (for example, execution/non-execution buttons) and allows the operator to select using the operation unit 22. be done. In the drug packaging device 1 of the present embodiment, the operator can select whether to measure excipients by itself, so various situations can be flexibly dealt with.

Here, regarding the excipient, when the operator selects to perform the weighing and packaging operation by the machine itself, the control unit 50 sets at least one of the first set value and the second set value. Based on this, the weight of the excipient to be weighed by the weighing unit 30 is determined. If the excipient weighed based on the determined weight is added to the medicine that is less than the first set value or the second set value, the medicine to which the excipient is added is the weight of the medicine that can be packaged. Since it satisfies the lower limit value, it becomes possible to package by the packaging unit 33 of the own machine (medicine packaging device 1).

Further, when the operator selects to perform the weighing operation for the excipient, the control unit 50 controls the weighing unit 30 based on at least one of the fourth set value and the fifth set value. can determine the weight of the excipient to be weighed out. As a result, the excipient can be weighed into the secondary container 93 in consideration of the packaging capability of another drug packaging device 95 that will package the excipient later.

The response selection unit 64 determines that the drug container 15 related to the drug indicated by the drug information is not arranged in the drug packaging device 1, or the amount of the drug contained in the drug container 15 is insufficient for the target amount based on the dispensing data. In this case, the operator can select one of the following multiple responses as a response for causing the packaging unit 33 to perform the packaging operation.

There are three possible responses that can be selected by the operator: replenishment response, drug container introduction response, and external weighing response. The replenishment correspondence refers to the correspondence of replenishing the medicine container 15 with medicine. The response to drug container introduction is a response to introduce a drug container 15 containing a required amount or more of drug into the drug packaging device 1 . The correspondence to external weighing means that the operator introduces into the medicine packaging device 1 an external weighing container 92 containing a predetermined amount (for all doses) of medicines prepared outside the medicine packaging device 1 .

Although there are various configurations for realizing the selection, the response selection unit 64 causes the display unit 21 to display options (for example, buttons for replenishment of medicine/introduction of medicine container/external weighing), and the operator uses the operation unit 22. It is conceivable to let them choose.

The guide section 65 can guide (instruct) the operator. For example, when at least one of the medicines indicated by the medicine information cannot be packaged due to the capacity of the packaging unit 33 of the device itself, the guide unit 65 distributes the medicine weighed by the weighing unit 30 to another medicine. The operator can be informed that the drug packaging device 95 should be used to package the medicine. In addition, the guide unit 65 is configured to enable the packaging unit 33 to perform the packaging operation when the medicine supplied from the medicine container 15 to the intermediate container 91 is insufficient for the target amount based on the dispensing data. , the operator can be notified that external weighing is available. Although there are various methods for realizing guidance to the operator, for example, it is conceivable to display an appropriate message on the display unit 21 . Guidance may be provided, for example, by voice, notification lamp, or the like.

The control unit 50 makes a judgment on the first condition or the second condition for the drug indicated by the drug information included in the dispensing data (hereinafter sometimes simply referred to as "the drug indicated by the drug information"). be able to. The number of drugs indicated by the drug information may be one or more than one.

The first condition is that the weight of each total dose of the medicine indicated by the medicine information is equal to or greater than the first set value. As described above, the first set value is a value based on the lower limit of the weight of the medicine that can be packaged by the packaging unit 33 (the weight of the total dose). The second condition is that the weight of each dose of the drug indicated by the drug information is equal to or greater than the second set value. As described above, the second set value is a value based on the lower limit of the weight of the medicine that can be packaged by the packaging unit 33 (weight for one dose). The first set value is determined, for example, according to the amount required for the medicine discharged from the medicine discharge part 32 to be uniformly deposited on the distribution tray 34a. Also, the second set value is determined, for example, according to the amount required to equalize the amount of medicine deposited uniformly on the distribution tray 34a and fed from the distribution tray 34a by the feeding section 34b.

The control unit 50 determines whether or not each drug indicated by the drug information satisfies both the first condition and the second condition. After the determination, if at least one of the drugs indicated by the drug information does not satisfy at least one of the first condition and the second condition, the control unit 50 prohibits the packaging operation by the packaging unit 33. do. That is, the control unit 50 causes the packaging unit 33 to perform the packaging operation when both the first condition and the second condition are satisfied for each medicine indicated by the medicine information. By the above-described processing, it is possible to prevent the packing operation from being performed when the packing unit 33 is not capable of packing in accordance with the prescription data request, so that the accuracy of the preparation can be ensured.

If at least one of the drugs indicated by the drug information does not satisfy at least one of the first condition and the second condition, the control unit 50 targets each of the drugs indicated by the drug information and sets the third condition. is satisfied. A third condition is that the weight of the total dose of the medicine is equal to or greater than the third set value. The third set value is a value smaller than the first set value, and as described above, is a value based on the lower limit of the weight of the medicine that can be weighed by the weighing section 30 . The third setting value may be determined in consideration of the minimum weighing value of weighing section 18 .

The control unit 50 prohibits the weighing operation by the weighing unit 30 for drugs that do not satisfy the third condition among the drugs indicated by the drug information. On the other hand, the control unit 50 permits the weighing operation by the weighing unit 30 with respect to the medicine that satisfies the third condition among the medicines indicated by the medicine information. Even if the medicine packaging device 1 does not have the ability to dispense medicines according to the dispensing data request and the control unit 50 prohibits the medicine packaging operation, the medicine packaging device 1 can perform the weighing operation to obtain the medicine. The operating efficiency of the packaging device 1 can be enhanced. In addition, since it is possible to prevent the weighing operation from being performed when the weighing section 30 is not capable of performing the weighing according to the prescription data request, the accuracy of the dispensing can be ensured.

When the third condition is satisfied, the medicine packaging device 1 performs the weighing action (in other words, the second action). When the control unit 50 prohibits the packing operation, the control unit 50 (the weighing selection unit 62) may allow the operator to select whether or not to perform the weighing operation for the medicine indicated by the medicine information. Therefore, it is possible to realize an operation that meets the operator's desire.

If at least one of the drugs indicated by the drug information does not satisfy at least one of the first condition and the second condition, the control unit 50 replaces the drug weighed by the weighing unit 30 with another drug. The guiding section 65 guides the operator as to what the packaging device 95 should be used for. As a result, the operator can quickly understand the situation, so that a series of operations including weighing and packaging can be performed smoothly as a whole.

When the guide unit 65 guides the use of another drug packaging device 95 in this manner, the control unit 50 makes a judgment on the fourth condition or the fifth condition for each drug indicated by the drug information. I do. A fourth condition is that the weight of each total dose of the medicine indicated by the medicine information is equal to or greater than a fourth set value. The fourth set value is set to a value equal to the lower limit of the weight of all doses that can be packaged by the other medicine packaging device 95, as described above. The fifth condition is that the weight of each dose of the drug indicated by the drug information is equal to or greater than the fifth set value. The fifth set value is set to a value equal to the lower limit of the weight for one dose that can be packaged by the other medicine packaging device 95, as described above. The control unit 50 controls the control unit 50 to determine whether the fourth setting value of the other medicine packaging device 95 is equal to or less than the total dose weight of each medicine indicated by the medicine information, and the fifth setting value is Select another medication dispensing device 95 that is less than or equal to the dose weight for each of the medications shown. As a result, the operator can be urged to use another medicine packaging device 95 suitable for the current dispensing data to perform packaging, so that smooth work can be realized.

The control unit 50 guides the operator through the guiding unit 65 that the medicine weighed by the weighing unit 30 should be packaged using the other selected medicine packaging device 95 .

The control unit 50 can make judgments on the first judgment condition and the second judgment condition. The first determination condition (arrangement condition) is that the drug container 15 containing the required drug indicated by the drug information is arranged in the drug packaging device 1 . The second determination condition (remaining amount condition) is that the drug container 15 arranged in the drug packaging device 1 contains more than the required amount of the drug indicated by the drug information. The control unit 50 determines whether or not each of the first determination condition and the second determination condition is satisfied for each drug indicated by the drug information.

This judgment can also be rephrased as a judgment as to whether or not the medicine packaging device 1 has prepared the necessary medicine in the necessary amount. By determining in advance whether the first determination condition and the second determination condition are satisfied, the medicine packaging device 1 can reliably and smoothly perform the packaging operation.

When determining that both the first determination condition and the second determination condition are satisfied, the control unit 50 causes the packaging unit 33 to perform the packaging operation. When the control unit 50 determines that the first determination condition and the second determination condition are not satisfied, the control unit 50 performs the above-described replenishment operation and the drug container operation as measures for causing the packaging unit 33 to perform the packaging operation. The operator is made to select which of the introduction support and the external weighing support by using the support selection unit 64 . Specifically, when the control unit 50 determines that the first determination condition is not satisfied, the control unit 50 responds to the introduction of the medicine container and the response to external weighing as measures for causing the packing unit 33 to perform the packing operation. The operator is made to select, using the response selection unit 64, which of , , and . Further, when the control unit 50 determines that the second determination condition is not satisfied, the control unit 50 performs either replenishment support or external weighing support as a response for causing the packing unit 33 to perform the packing operation. The operator is made to select using the correspondence selection unit 64 as to whether. There are several methods for preparing the missing medicine, but in this embodiment, the medicine can be prepared according to the method selected by the operator, so appropriate measures can be taken according to the situation.

This take-out is performed via the second take-out section 26 provided in the drug packaging device 1 . The second take-out position P6 also serves as a position (introduction position) for introducing the external weighing container 92 or the intermediate container 91 containing the medicine weighed by the weighing device 80 into the medicine packaging device 1. good.

The third take-out position P7 is a secondary container 93 that stores the medicine weighed by the weighing unit 30 when the medicine is weighed by the medicine packaging device 1 but not packaged. It is a position for taking out to the outside of 1. This take-out is performed via the third take-out part 27 provided in the medicine packaging device 1 . Therefore, it can be said that the third take-out position P7 is a temporary position at which the secondary container 93 can be taken out of the drug packaging device 1 .

The first extraction section 25, the second extraction section 26, and the third extraction section 27 may be, for example, opening and closing doors, but are not limited to this. The medicine packaging device 1 of the present embodiment transports the container to the outside of the medicine packaging device 1 simply by transporting the container to the first take-out position P5, the second take-out position P6, or the third take-out position P7 by the transport unit 14. Since it can be put into a detachable state, simple handling is realized.

The discharge standby position P8 is a position where the intermediate container 91 is kept waiting after the weighing unit 30 completes the weighing of the medicine and before the packaging unit 33 discharges the medicine. The discharge standby position P8 is also a position (introduction position) where the external weighing container 92 or the intermediate container 91 containing the medicine weighed by the weighing device 80 is set to be introduced into the medicine packaging device 1 . The ejection standby position P8 is set in the ejection standby section 23 described above. Further, the discharge standby position P8 may also serve as the first removal position P5, the second removal position P6, or the third removal position P7.

The discharge position P9 is the position of the intermediate container 91 or the external weighing container 92 when the drug is discharged from the drug discharge section 32 . The operator can introduce the external measuring container 92 or the intermediate container 91 into the drug packaging device 1 by directly setting the external measuring container 92 or the intermediate container 91 containing the drug in the drug discharging section 32 . At this time, the introduction position is set to the medicine discharge portion 32 .

The cleaning standby position P<b>10 is a position where the intermediate container 91 or the external weighing container 92 waits for cleaning in the cleaning section 38 . The cleaning standby position P10 is set in the cleaning standby section 37 described above.

The cleaning position P<b>11 is a position where the intermediate container 91 or the external weighing container 92 is cleaned by the cleaning section 38 .

In this embodiment, the discharge standby position P8 and the cleaning standby position P10 function as relay points for transporting the container by the transport unit 14 .

More specifically, the first transport section 14a includes the first standby position P1, the second standby position P2, the third standby position P3, the weighing position P4, the first take-out position P5, the second take-out position P6, the 3 It is configured such that the container can be transported between the take-out position P7, the discharge standby position P8, and the cleaning standby position P10. On the other hand, the second conveying section 14b is configured to be able to convey the container between the discharge standby position P8, the discharge position P9, and the cleaning standby position P10.

Therefore, after the control unit 50 transports the intermediate containers 91 and the like to the discharge standby position P8 by the first transport unit 14a, the transported intermediate containers 91 and the like can be transported by the second transport unit 14b at an appropriate timing. Further, after the intermediate containers 91 and the like are transported to the cleaning standby position P10 by the second transport portion 14b, the transported intermediate containers 91 and the like can be transported by the first transport portion 14a at an appropriate timing.

Next, the weighing device 80 will be described. The weighing device 80 includes a control unit 81, a weighing unit 82, an information processing unit 83, and a display unit 84, as shown in FIG. The weighing unit 82, the information processing unit 83, and the display unit 84 are electrically connected to the control unit 81, respectively. The metering device 80 is capable of metering the medicament contained in the external metering container 92 . When intermediate container 91 is used for external metering, metering device 80 measures the drug contained in intermediate container 91 .

The control unit 81 can communicate with the control unit 50 of the medicine packaging device 1 and can receive dispensing data stored in the storage unit 61 of the medicine packaging device 1 . The weighing device 80 sends the weighing result to the medicine packaging device 1 when the weighing (measurement of the medicine lacking in the target amount, etc.) is completed.

The weighing unit 82 has substantially the same configuration as the weighing unit 18 of the medicine packaging device 1, so description thereof will be omitted. The weighing device 80 weighs the medicine that the operator takes out from a suitable medicine bottle or the like onto a weighing dish or the like. Note that the weighing device 80 may weigh the drug together with the external weighing container 92 while the drug is stored in the external weighing container 92 .

The information processing section 83 is arranged near the weighing section 82 . The information processing section 83 has a barcode reader and an RFID reader/writer. The barcode reader can read the barcode provided on the medicine bottle or the like. The RFID reader/writer can read and write the contents of the information recording section 92 e of the external weighing container 92 .

The information processing section 83 reads the information stored in the barcode of the medicine bottle and the information recording section 92e of the external weighing container 92, and performs processing to change the information stored in the information recording section 92e. . Specifically, the information processing unit 83 reads the medicine identification information of the medicine bottle or the like from the bar code provided on the medicine bottle or the like, and the control unit 81 identifies the medicine contained in the medicine bottle or the like. The information processing section 83 also reads the dispensing data (specifically, the dispensing data number) stored in the information recording section 92e of the external weighing container 92 . The weighing device 80 acquires the dispensing data corresponding to the read dispensing data (dispensing data number) from the control unit 50 of the medicine packaging device 1 . At that time, the weighing device 80 also acquires information on the drug to be weighed (including the target amount of the drug). Then, the control unit 81 determines to which of the drugs indicated by the drug information included in the dispensing data acquired from the control unit 50 of the drug packaging device 1 the drug specified based on the drug specifying information corresponds to. Identify. If the control unit 81 determines that the drug specified based on the drug specifying information matches any of the drugs indicated by the drug information included in the dispensing data, the control unit 81 selects the drug indicated by the matching drug information as a weighing target. When the weighing of the drug selected as the weighing target is completed, the weighing device 80 sends the weighing result including the measured amount of the drug together with the dispensing data acquired from the control unit 50 of the drug packaging device 1 via the control unit 81. , to the control unit 50 of the medicine packaging device 1 . The control unit 50 of the medicine packaging device 1 receives the weighing result and updates the dispensing data stored in the storage unit 61 .

The information recording unit 92 e can read and write information by the information processing unit 83 , and at the same time, can also read and write information by the second information processing unit 19 of the medicine packaging device 1 . Therefore, even if the medicine packaging device 1 and the weighing device 80 are not configured to be communicable, information (dispensing data, weighing results) can be exchanged between the medicine packaging device 1 and the weighing device 80 via the external weighing container 92. can be delivered.

The information processing section 83 can change the display contents of the information display section 92 d of the external weighing container 92 . When the weighing of the drug by the weighing device 80 is finished, the information processing section 83 causes the information display section 92d of the external weighing container 92 to display the measured amount (weighing result). Further, as the information regarding dispensing, the information display section 92d may display that the amount of medicine corresponding to the target amount is contained and preparation for introduction into the medicine packaging device 1 is completed.

The display unit 84 is a device having a display screen capable of displaying characters and the like. The display unit 84 is arranged at an appropriate position on the weighing device 80 . The display unit 84 can be configured as a display with a touch panel, for example. The display unit 84 can display, for example, the name of the drug, the target amount of the drug, the measured amount, and the like. Further, the display unit 84 can display the result of the determination made by the control unit 81 as to whether or not the medicine in the medicine bottle or the like matches the medicine to be weighed. This makes it possible to confirm that the drug in the medicine bottle or the like is the required drug based on the dispensing data.

Next, with reference to FIGS. 7 to 9, presetting processing and the like when using the drug packaging device 1 in the dispensing system 100 will be described. 7 to 9 show flowcharts of presetting processing and the like in order.

In the presetting process, first, the control unit 50 displays a dispensing data input screen on the display unit 21 (step S101 in FIG. 7). Dispensing data includes, for example, a person taking the drug, drug information, a target amount, a measurement result (a measured amount or an insufficient amount relative to the target amount), a dispensing data number for identifying each dispensing data, and the like. The drug information is information including the name of one or more drugs to be taken, dosage form (powder/tablet/capsule/liquid/external medicine), method of administration, and dosage. The dosing method refers to the number of doses per day, the timing of dosing, and the number of days of dosing. weight), etc. The control unit 50 operates the medicine packaging device 1 based on the input dispensing data.

The operator uses the operation unit 22 to input dispensing data on this input screen. The dispensing data input by the operator are stored in the storage section 61 of the control section 50 . In addition to the configuration in which the operator manually inputs the dispensing data, the dispensing data may be input to the medicine packaging device 1 by communication from an external information processing device such as a dispensing device control device.

When the input of dispensing data is completed, the control unit 50 determines whether or not the drug indicated by the drug information includes powder (step S102). This determination is made based on information about the dispensing. When determining that the drug indicated by the drug information does not contain powder, the control unit 50 ends the presetting process.

When determining that the medicine indicated by the medicine information includes powder, the control unit 50 determines whether or not the powder is a preparation to be dissolved in a liquid medicine (step S103). In addition, in the following description, the powder here is called a medicine.

If it is determined that the medicine is to be dissolved in a liquid medicine, the control unit 50 determines whether or not the second action (that is, the action of not packing the medicine after weighing it) can be executed (step S104). ). Specifically, for each drug indicated by the drug information, the control unit 50 determines whether or not the weight of the entire dose of the drug is equal to or greater than the third set value. The third set value is a value based on the lower limit of the weight of the medicine that can be weighed by the weighing unit 30, as described above. Then, when the weight of the total dose of any of the drugs indicated by the drug information is equal to or greater than the third set value, the control unit 50 determines that the second operation can be executed. The control unit 50 causes the medicine packaging device 1 to perform a weighing operation for medicines indicated by the medicine information whose total weight is equal to or greater than the third set value. The control unit 50 determines that the second operation cannot be executed when the weight of all the medicines indicated by the medicine information is less than the third set value.

When determining that the second operation cannot be performed, the control unit 50 ends the presetting process. On the other hand, if it is determined that the second action can be performed, the control unit 50 ends the presetting process (step S105), and sets the weighing action ( setting of the second operation).

In the weighing operation setting, the control unit 50 determines whether or not the medicine indicated by the medicine information is in the medicine packaging device 1 (step S106). This determination is made based on the arrangement information of the medicine container 15 and the medicine information included in the dispensing data.

When determining that the medicine is in the medicine packaging device 1, the control unit 50 determines that the remaining amount of the medicine in the medicine container 15 is equal to or greater than the amount to be measured (the target amount based on the dispensing data) for the medicine indicated by the medicine information. It is determined whether or not (step S107). That is, the control unit 50 determines whether or not the drug container 15 contains more than the required amount of the drug indicated by the drug information. The amount to be weighed corresponds to the weight of the total dose for each drug.

Various methods are conceivable for obtaining the amount of medicine contained in the medicine container 15 . For example, the control unit 50 stores in advance the weight of the medicine in the initial state when the medicine is full, and subtracts the weight of the medicine already discharged from the medicine container 15 by the medicine packaging device 1 from that weight. By doing so, the remaining amount of the drug can be obtained. If the remaining amount of medicine is stored in the information recording section 71 of the medicine container 15 by the first information processing section 16, the remaining amount of medicine in the medicine container 15 can be obtained by the first information processing section 16 as needed. For example, the drug supply mechanism 17 may be provided with a weighing unit to detect the weight of the drug container 15 to obtain the remaining amount of the drug in the drug container 15 .

If it is determined in step S107 that the amount of medicine remaining in the medicine container 15 is equal to or greater than the amount to be measured, the controller 50 causes the medicine packaging device 1 to perform the second operation. When the medicine packaging device 1 operates continuously based on two or more pieces of dispensing data, if the medicine packaging device 1 performs the weighing operation related to the previous dispensing data, the control unit 50 controls the next dispensing data. waits for the weighing operation. Here, if the weighing operation related to the previous dispensing data has been completed, the control unit 50 starts the weighing operation related to the next dispensing data. On the other hand, if it is determined that the amount of medicine remaining in the medicine container 15 is not equal to or greater than the amount to be measured, or if it is determined in step S106 that there is no medicine in the medicine packaging device 1, the controller 50 The operator is guided to perform a replenishment response to replenish the medicine container 15 with the medicine, or a medicine container introduction response to introduce the medicine container 15 containing more than the necessary amount of medicine into the medicine packing apparatus 1 (step S108). ). This guidance is provided by the display of the display unit 21 or the like.

In step S107, if it is determined that the amount of medicine remaining in the medicine container 15 is equal to or greater than the amount to be weighed, the controller 50 performs container allocation setting. In the container allocation setting, the control unit 50 designates a container to accommodate each drug indicated by the drug information. This is done by assigning container-specific information to each drug indicated by the drug information. Since the medicine supplied from the medicine container 15 is stored in the secondary container 93 in the second operation, the controller 50 assigns the container-specific information of the secondary container 93 to each medicine indicated by the medicine information.

In this way, when the weighing operation setting is completed and the medicine packaging device 1 is ready to start the weighing operation, the control unit 50 causes the medicine packaging device 1 to perform the second operation.

If it is determined in step S103 that the medicine is not a preparation to be dissolved in a liquid medicine, the control unit 50 determines whether or not the first action (that is, the action of packaging) can be executed (step S109). That is, the control unit 50 determines whether or not the first condition and the second condition are satisfied. Specifically, for each drug indicated by the drug information, the control unit 50 sets a first condition that the weight of all doses is equal to or greater than a first set value and a second condition that the weight of one dose is It is determined whether a second condition of being greater than or equal to the value is satisfied. The first set value and the second set value are values based on the lower limit of the weight of the medicine that can be packaged by the packaging unit 33, as described above. When both the first condition and the second condition are satisfied for all drugs indicated by the drug information, the control unit 50 determines that the first operation can be executed for the dispensing data related to this drug information. do. When at least one of the first condition and the second condition is not satisfied for at least one of the drugs indicated by the drug information, the control unit 50 executes the first operation on the dispensing data related to this drug information. Decide you can't. In this case, the addition of excipients can be selected by the excipient selection unit 63 so that the drug satisfies the first condition and the second condition.

When determining that the first action can be executed, the control unit 50 ends the presetting process, and sets the weighing action and the packing action (first operation setting) is performed (step S110).

In setting the weighing operation and the packing operation, the control unit 50 refers to the master information stored in the storage unit 61 or the like, and the drug container 15 containing each drug indicated by the drug information is registered in the master information. (Step S111 in FIG. 8).

When determining that the medicine container 15 is registered, the control unit 50 determines whether or not each medicine indicated by the medicine information is present in the medicine packaging device 1 (step S112). That is, the control unit 50 determines whether or not the first determination condition is satisfied. Specifically, the control unit 50 determines whether or not the drug container 15 containing the required drug is arranged in the drug packaging device 1 for each drug indicated by the drug information. This determination is made based on the arrangement information of the medicine container 15 and the medicine information included in the dispensing data.

When it is determined that the medicine is in the medicine packaging device 1, the control unit 50 determines whether or not the remaining amount of the medicine indicated by the medicine information in the medicine container 15 is equal to or greater than the amount to be measured (step S113). This corresponds to the second determination condition described above. Specifically, the control unit 50 determines whether or not the drug container 15 arranged in the drug packaging device 1 contains more than the required amount of each drug indicated by the drug information. For example, the control unit 50 calculates the remaining amount of the drug and checks whether or not the remaining amount of the drug is insufficient for the total amount of the drug indicated by the drug information, as in step S107. The amount to be weighed corresponds to the weight of the total dose for each drug.

If it is determined in step S113 that the amount of medicine remaining in the medicine container 15 is equal to or greater than the amount to be measured, the controller 50 causes the medicine packaging device 1 to perform the first operation based on the set operating conditions. . When the medicine packaging device 1 is operated continuously based on two or more dispensing data, if the medicine packaging device 1 has performed the weighing operation related to the previous dispensing data, the control unit 50 controls the next dispensing data. waits for the weighing operation. Here, if the weighing operation related to the previous dispensing data has been completed, the control unit 50 starts the weighing operation related to the next dispensing data. On the other hand, if it is determined that the amount of medicine remaining in the medicine container 15 is not equal to or greater than the amount to be measured, or if it is determined in step S112 that there is no medicine in the medicine packaging device 1, the controller 50 The operator is guided to perform a replenishment response to replenish the medicine container 15 with medicine, or a medicine container introduction response to introduce a medicine container 15 containing more than the required amount of medicine into the medicine packing apparatus 1 (step S121). ). This guidance is provided by the display of the display unit 21 or the like. After that, the process returns to step S112.

When determining that the amount of medicine remaining in the medicine container 15 is greater than or equal to the amount to be weighed, the controller 50 sets the operating conditions for the medicine packaging device 1 in the setting of the weighing operation and the packaging operation. The control unit 50 displays a setting screen regarding weighing, discharging, distribution, and packaging on the display unit 21 as a setting screen (step S114). For example, the operator can specify the container (intermediate container 91) to be used in the weighing operation and packing operation for each drug. In addition, the operator can operate the operation unit 22 to specify the ejection speed (strength of vibration) at which the medicine is ejected, the speed at which the medicine is packaged, and the like. Further, the control unit 50 performs container allocation setting. In the container allocation setting, the control unit 50 designates a container to accommodate each drug indicated by the drug information. This is done by assigning container-specific information to each drug indicated by the drug information. Since the medicine is contained in the intermediate container 91 in the first operation, the controller 50 assigns the container-specific information of the intermediate container 91 to each medicine indicated by the medicine information. Note that the setting screen may allow the operator to specify the container (intermediate container 91) to be used in the packaging operation for each medicine as a setting for weighing. Also, the operator may be able to designate the distribution unit 34 and the drug discharge unit 32 to be used in the packaging operation. The control unit 50 registers the settings designated by the operator (step S115). A weighing operation, a discharging operation, a distribution operation, and a packaging operation, which will be described later, are processed based on the information registered here. In this way, when the weighing operation and setting of the packaging operation are completed, and the medicine packaging device 1 is ready to start the weighing operation, the control unit 50 causes the medicine packaging device 1 to perform the first operation.

In step S121, the control unit 50 responds to replenishment by replenishing the drug container 15 with the shortage of the drug, or by introducing the drug container 15 containing more than the necessary amount of the drug into the drug packaging device 1. guide the operator to perform Specifically, the control unit 50 (response selection unit 64) displays a selection screen for allowing the operator to specify which of replenishment support and drug container introduction support for drugs that are not prepared in the drug packaging device 1. Displayed on the display unit 21 . Then, the control unit 50 registers the settings specified by the operator. After that, the process returns to step S112.

If it is determined in step S112 that there is no drug in the drug packaging device 1, or if it is determined in step S113 that the remaining amount of drug in the drug container 15 is not equal to or greater than the amount to be measured, the drug is measured externally. A screen for inquiring whether or not to perform external weighing using the container 92 is displayed on the display unit 21 (step S116). In this case, the operator can use the operation unit 22 to specify external weighing support on this selection screen. In this embodiment, the handling of medicines not prepared in the medicine packaging device 1 is set by the operator's designation on the selection screen. You may preset which correspondence is performed among correspondence.

When the operator designates to perform external weighing using the external weighing container 92 (step S117), the control unit 50 displays weighing, discharge, distribution, and packaging as an operation condition setting screen for the medicine packaging device 1. is displayed on the display unit 21 (step S118). Then, the control unit 50 registers the settings specified by the operator (step S119). Further, the control unit 50 performs container allocation setting. In the container allocation setting, the control unit 50 designates a container to accommodate each drug indicated by the drug information. This is done by assigning container-specific information to each drug indicated by the drug information. Since the medicine is contained in the intermediate container 91 in the first operation, the controller 50 assigns the container-specific information of the intermediate container 91 to each medicine indicated by the medicine information. Since the medicines that are compatible with external weighing are stored in the external weighing container 92, the control unit 50 assigns the container-specific information of the external weighing container 92 to the drugs that are compatible with external weighing among the drugs indicated by the drug information. Note that the setting screen may allow the operator to specify the container (intermediate container 91 or external weighing container 92) used in the packaging operation for each medicine as a setting for weighing. Also, the operator may be able to designate the distribution unit 34 and the drug discharge unit 32 to be used in the packaging operation. A weighing operation, a discharging operation, a distribution operation, and a packaging operation, which will be described later, are processed based on the information registered here. In this way, when the weighing operation and setting of the packaging operation are completed, and the medicine packaging device 1 is ready to start the weighing operation, the control unit 50 causes the medicine packaging device 1 to perform the first operation.

When the container-specific information of the external weighing container 92 is assigned to the medicine to be externally weighed, the control unit 50 selects the external weighing container 92 to be used based on the container-specific information. are selected from the external weighing containers 92 (step S120). As described above, a plurality of external weighing containers 92 are stored in the second storage unit 12. Even if these external weighing containers 92 include those with different sizes of the storage units 92a, good. In this case, the control unit 50 selects an appropriate size according to the target amount of the drug based on the drug information included in the dispensing data and the information on the plurality of external weighing containers 92 recorded in advance in the storage unit 61 . A selection of external weighing containers 92 is made. As a result, the external weighing container 92 suitable for the situation can be used for the external weighing.

If it is determined in step S112 that there is no drug in the drug packaging device 1, or if it is determined in step S113 that the remaining amount of drug in the drug container 15 is not equal to or greater than the amount to be measured, the external weighing support cannot be selected. It may be configured as follows. In this case, the processes of steps S116 and S117 are omitted.

When replenishment support or drug container introduction support is selected, the control unit 50 provides guidance to perform refill support or drug container introduction support (step S121). This guidance is provided by the display of the display unit 21 or the like. After that, the process returns to step S112. Normally, such guidance prompts the user to secure necessary medicines inside the medicine packaging device 1, but after step S121, there are cases where replenishment or medicine container introduction is not performed. In this case, when the medicine packaging device 1 is used, the first operation is performed in a state in which the required medicine is not secured. Further, if the configuration does not allow acquisition of the remaining amount of medicine contained in the medicine container 15, the determination in step S113 is omitted.

When it is determined in step S111 that the drug container 15 is not registered, the control unit 50 determines to perform external weighing using the external weighing container 92 (step S122). After that, the processing from step S118 to step S120 described above is performed, and if the medicine packaging device 1 is ready to start the weighing operation, the control unit 50 causes the medicine packaging device 1 to perform the first operation. .

When it is determined in step S109 in FIG. 7 that the first operation cannot be executed, the control unit 50 prohibits the packaging operation by the packaging unit 33 (step S123). Then, the control unit 50 determines whether or not the second operation (that is, the operation of not packing the medicine after weighing it) can be executed (step S124 in FIG. 9). Specifically, the control unit 50 determines whether or not the third condition is satisfied for each drug indicated by the drug information. The control unit 50 determines that the weighing operation can be executed for the medicine determined to satisfy the third condition among the medicines indicated by the medicine information. When determining that the third condition is not satisfied among the medicines indicated by the medicine information, the control unit 50 determines that the weighing operation cannot be executed for the medicines that do not satisfy the third condition.

When determining that the weighing operation cannot be executed for all the medicines indicated by the medicine information, the control unit 50 prohibits the weighing operation by the weighing unit 30 (step S125), and ends the presetting process. On the other hand, if it is determined that at least one drug out of the drugs indicated by the drug information can be weighed out, the control unit 50 ends the presetting process, and causes the drug packaging device 1 to perform the second action. A weighing operation setting (setting of a second operation) is performed (step S126). As for the execution of the second action, the control section 50 (weighing selection section 62) can make settings for performing the second action according to the operator's selection using the operation section 22. FIG.

Then, in the weighing operation setting, the control unit 50 determines whether or not the medicine indicated by the medicine information is present in the medicine packaging device 1 (step S127). That is, the control unit 50 determines whether or not the drug container 15 containing the required drug is arranged in the drug packaging device 1 for the drug indicated by the drug information. When it is determined that the medicine is in the medicine packaging device 1, the control unit 50 determines whether or not the remaining amount of the medicine indicated by the medicine information in the medicine container 15 is equal to or greater than the amount to be measured (step S128).

If it is determined in step S128 that the amount of medicine remaining in the medicine container 15 is equal to or greater than the amount to be measured, the controller 50 causes the medicine packaging device 1 to perform the second operation. On the other hand, if it is determined that the amount of medicine remaining in the medicine container 15 is not equal to or greater than the amount to be measured, or if it is determined in step S127 that there is no medicine in the medicine packaging device 1, the controller 50 The operator is guided to perform a replenishment response to replenish the medicine container 15 with the medicine, or a medicine container introduction response to introduce the medicine container 15 containing more than the necessary amount of medicine into the medicine packing apparatus 1 (step S134). ). This guidance is provided by the display of the display unit 21 or the like. After that, the process returns to step S127.

If it is determined in step S128 that the amount of medicine remaining in the medicine container 15 is greater than or equal to the amount to be measured, the controller 50 performs container allocation setting. In the container allocation setting, the control unit 50 designates a container to accommodate each drug indicated by the drug information. This is done by assigning container-specific information to each drug indicated by the drug information. Since the medicine supplied from the medicine container 15 is stored in the secondary container 93 in the second operation, the controller 50 assigns the container-specific information of the secondary container 93 to each medicine indicated by the medicine information.

In this way, when the weighing operation setting is completed and the medicine packaging device 1 is ready to start the weighing operation, the control unit 50 causes the medicine packaging device 1 to perform the second operation.

In this embodiment, when it is determined in step S128 that the amount of medicine remaining in the medicine container 15 is equal to or greater than the amount to be weighed, the control unit 50 selects the medicine to be used from among the plurality of other medicine packaging devices 95. It guides the other drug packaging device 95 to be delivered. More specifically, the control unit 50 determines that the fourth setting value among the plurality of other medicine packaging devices 95 is equal to or less than the total dose weight of each of the medicines indicated by the medicine information, and the fifth setting value is equal to or less than the weight of one dose of each drug indicated by the drug information (step S129). Then, the control unit 50 guides the use of the other selected medicine packaging device 95 (step S130). The fourth set value and the fifth set value are values based on the lower limit of the weight of the medicine that can be packaged by the other medicine packaging device 95, as described above. This guidance is provided by the display of the display unit 21 or the like. Note that if the configuration does not allow acquisition of the remaining amount of medicine contained in the medicine container 15, the determination in step S128 is omitted.

In step S129, the weight of all doses or the weight of one dose is not equal to or greater than the lower limit of the weight of drugs that can be packaged by another drug packaging device 95 (the fourth condition and the fifth condition are not satisfied). In some cases, the drug packaging device 95 must be selected. In this case, the control unit 50 displays on the display unit 21 a selection screen for adding excipients when the medicine packaging device 1 performs the second operation (step S131). The operator selects whether or not to add an excipient using the operation unit 22 (excipient selection unit 63) on this selection screen. Based on the selection result by the operator, the control unit 50 determines whether or not the excipient is to be weighed by the weighing unit 30 (step S132).

When it is selected to perform the excipient weighing operation by the weighing unit 30, the control unit 50 determines the weight of the excipient to be weighed by the weighing unit 30 (step S133). The excipient weight is determined based on at least one of the fourth setting value and the fifth setting value for the selected other drug packaging device 95 . Then, as the weighing operation setting, the control unit 50 performs container allocation setting for excipients. In the container allocation setting, the control unit 50 designates the container containing the excipient. This is done by assigning container specific information to the excipient. Since the excipient is stored in the secondary container 93 in the second operation, the control unit 50 assigns the container-specific information of the secondary container 93 to the excipient. The container-specific information assigned to the excipient may be the container-specific information of the secondary container 93 that is the same as the drug to which the excipient is added, or the container-specific information of the secondary container 93 that is different from the drug to which the excipient is added. may be

Next, with reference to FIGS. 10 to 13, the process related to the intermediate container 91 when performing the first action (that is, the action of packing) will be described. FIG. 10 is a flow chart showing the process when the external weighing correspondence is not performed among the processes related to the intermediate container 91 when performing the first operation. FIG. 11 is a diagram showing the route of the intermediate container 91 when the processing of FIG. 10 is performed. FIG. 12 is a continuation of the processing of FIG. 10 and is a flow chart showing the processing when external weighing correspondence is performed. FIG. 13 is a diagram showing the route of the intermediate container 91 when the process of FIG. 12 is performed.

In advance, the third information processing unit 20 stores information recording units (information recording unit 91e, information recording It reads container-specific information from the unit 92e and the information recording unit 93e) and sends storage information of the container in the storage unit to the control unit 50. FIG. The storage information is information that associates container-specific information with information about the storage position of the container in the storage unit. The control unit 50 causes the storage unit 61 to store the storage information sent from the third information processing unit 20 .

The first action is performed when the setting of the first action is performed in the presetting process, as shown in step S110 of FIG. 10 is performed when the external weighing support using the external weighing container 92 is not selected at the time of setting the weighing and packaging operations.

First, the control unit 50 selects an intermediate container to be transported from among the intermediate containers 91 stored in the first storage unit 11 based on storage information and container unique information assigned to each drug indicated by the drug information. Determine 91. At this time, the third information processing section 20 writes the dispensing data (including at least the dispensing data number) to the information recording section 91 e of the intermediate container 91 . Then, the control unit 50 controls the first transport unit 14a to transport the intermediate container 91 from the first standby position P1 to the weighing position P4 (step S201, (1) in FIG. 11). Next, the control unit 50 controls the drug supply mechanism 17 to control the drug container containing the drug corresponding to the intermediate container 91 to be transported, which is one of the drugs indicated by the drug information included in the dispensing data. 15 is moved above the mounting table 18a (intermediate container 91) (step S202). The movement of the drug container 15 may be performed after the transportation of the intermediate container 91, or the movement of the drug container 15 and the transportation of the intermediate container 91 may be performed in parallel.

Next, the control unit 50 controls the drug supply mechanism 17 to operate the drug supply mechanism targeting the drug container 15 moved above the intermediate container 91, and starts supplying the drug to the intermediate container 91 ( step S203).

The operation of measuring medicine from the medicine container 15 to the intermediate container 91 (steps S201 to S203) is performed for each kind of medicine indicated by the medicine information included in the dispensing data. If the target amount of medicine exceeds the storage upper limit of the intermediate container 91 , one type of medicine may be divided and supplied to a plurality of intermediate containers 91 .

The control unit 50 supplies the medicine so that the measured amount calculated by the weighing unit 18 matches the target amount based on the dispensing data. When the measured amount matches the target amount based on the dispensing data, the control unit 50 determines that the weighing has been completed (step S204). When the weighing is completed, the control unit 50 controls the second information processing unit 19 to display the measured amount on the information display unit 91d and store it in the information recording unit 91e (step S205).

At this time, the information display section 91d can display, for example, a dispensing data number, a drug name, a doser, a target amount, and a measured amount as the dispensing data. In addition, as information on dispensing, for example, information indicating that the weighing of the medicine has been completed can also be displayed. The drug name is the name of the drug supplied to the intermediate container 91 . The dosing person is information for identifying the dosing person, such as the name and age of the dosing person. The target amount is a value based on dispensing data and is the amount of medicine to be weighed out in the intermediate container 91 . The measured amount is the weight of the drug supplied to the intermediate container 91 measured by the weighing unit 18 . At least part of the information displayed in the information display section 91d is recorded in the information recording section 91e.

Next, the control unit 50 controls the first conveying unit 14a and the second conveying unit 14b to convey the intermediate container 91 from the weighing position P4 to the discharging position P9 (step S206, (2) and (3)), the intermediate container 91 is attached to the container attachment portion 32a (step S207).

When the opening/closing portion 91c of the intermediate container 91 is moved to switch from the closed state to the open state, the control unit 50 controls the vibration device 32b to generate vibration, thereby discharging the drug to the distribution unit 34 (step S208, ejection action). The medicine discharged to the distribution section 34 is packaged by the predetermined unit packaging amount by the packaging section 35 as described above, and delivered to a predetermined position ((4) in FIG. 11).

When the medicine is completely discharged to the distribution unit 34, the control unit 50 controls the second conveying unit 14b to move the intermediate container 91 from the discharge position P9 to the cleaning standby position P10 (step S209, ( 5)). The control unit 50 moves the intermediate container 91 to the cleaning position P11 at an appropriate timing (step S210, (6) in FIG. 11), and controls the cleaning unit 38 to clean the intermediate container 91 (step S211).

After the cleaning is completed, the control unit 50 returns the intermediate container 91 to the cleaning standby position P10 ((7) in FIG. 11), controls the first transport unit 14a, and transports the intermediate container 91 to the first standby position P1. (step S212, (8) in FIG. 11). When the cleaning of the intermediate container 91 is completed, the third information processing section 20 erases the display contents of the information display section 91d. As described above, the intermediate container 91 returns to its original position. Therefore, the intermediate container 91 can be used repeatedly when it is necessary to discharge again.

If it is determined in step S204 that the weighing is not completed, the control unit 50 guides the operator to perform replenishment or drug container introduction as in step S121. For example, when the supply mechanism is performing an operation for supplying the medicine from the medicine container 15, the medicine supplied to the intermediate container 91 is insufficient for the target amount, and the weighing unit 18 If the measured amount does not increase, it is determined that the weighing is not completed, and the operation of the feeding mechanism is stopped. After that, when replenishment support or drug container introduction support is performed, the process returns to step S203 and the supply of the drug to the intermediate container 91 is started (restarted). For example, after step S121 in FIG. 8, if replenishment or drug container introduction is not carried out according to the guidance, a shortage of drugs will occur. Further, if the configuration is such that the remaining amount of the medicine contained in the medicine container 15 cannot be obtained, shortage of the medicine may occur.

When determining that the weighing is not completed, the control unit 50 controls the second information processing unit 19 to display the current measurement amount on the information display unit 91d of the intermediate container 91 (see FIG. 12). step S214). At this time, information such as the name of the drug, the person taking the drug, and the target dose can be displayed together on the information display section 91d. Instead of or in addition to the target amount and the measured amount, the shortage amount of the medicine with respect to the target amount may be displayed on the information display section 91d. Further, as the information regarding dispensing, information may be displayed indicating that the weighing of the medicine has not been completed and the amount of the contained medicine is insufficient for the target amount. Then, the control unit 50 updates the currently measured amount or the insufficient amount with respect to the target amount included in the dispensing data. Further, the control unit 50 may control the second information processing unit 19 to write the shortage amount of the medicine with respect to the current measured amount or the target amount in the information recording unit 91 e of the intermediate container 91 . As a result, it is possible to prevent the intermediate container 91 from being mixed up, and the operator or the like can easily understand necessary information such as which medicine should be weighed and how much of it remains. By reading the information recorded in the information recording section 91e with an appropriate information processing device, an operator or the like can easily grasp necessary information such as which medicine should be weighed and how much remains.

If it is determined that the weighing has not been completed, the intermediate container 91, which is in the middle of supplying the drug, is used to perform external weighing, thereby allowing the weighing operation and the packaging operation to be continued. In this case, the control unit 50 controls the first conveying unit 14a to convey the intermediate container 91 in which the supply of medicine is incomplete from the weighing position P4 to the first take-out position P5 (step S215, ( 2)). The operator takes out the intermediate container 91 from the first take-out position P5 to the outside of the drug packaging device 1, supplies the intermediate container 91 with a drug taken out of a drug bottle or the like, and weighs the drug with the weighing device 80.

The operator causes the information recording section 91e of the intermediate container 91 taken out from the first take-out position P5 to be read by the information processing section 83 of the weighing device 80 . The weighing device 80 acquires the dispensing data number and container unique information from the information recording unit 91e. The weighing device 80 acquires the corresponding dispensing data from the control unit 50 of the medicine packaging device 1 based on the information acquired from the information recording unit 91 e and displays the acquired dispensing data on the display unit 84 . Based on the information acquired from the information recording unit 91e, the weighing device 80 also specifies which of the drugs indicated in the drug information included in the dispensing data is to be weighed. The display unit 84 displays the medicine specified as the target of measurement by distinguishing it from other medicines by highlighting or the like. In addition, the display unit 84 also displays the current measurement amount of the medicine specified as the measurement target or the amount of the medicine lacking the target amount. Next, the operator causes the information processing section 83 of the weighing device 80 to read the bar code (information recording section 71) of the medicine bottle or the like. Thereby, the control unit 81 of the weighing device 80 acquires the stored drug information. The control unit 81 collates the drug specified as the object to be weighed with the stored drug information to be acquired. If the collation results match, the operator uses the weighing device 80 to weigh the insufficient amount of medicine and supplies the weighed medicine to the intermediate container 91 . After weighing the medicine, the weighing device 80 uses the control part 81 to send the weighing result including the measured amount of medicine together with the dispensing data acquired from the control unit 50 of the medicine packaging device 1 to the medicine packaging device 1 . Send to the control unit 50 . The control unit 50 of the medicine packaging device 1 receives the weighing result and updates the dispensing data stored in the storage unit 61 .

After finishing the weighing of the drug by the weighing device 80, the information processing section 83 may cause the information display section 91d of the intermediate container 91 to display the measured amount (weighing result). Further, as the information about dispensing, the information display section 91d may display that the amount of medicine corresponding to the target amount is contained and preparation for introduction into the medicine packaging device 1 is completed.

Next, the control unit 50 determines whether or not the intermediate container 91 is set at the discharge standby position P8 (step S216). When determining that the intermediate container 91 is not set at the discharge standby position P8, the control section 50 repeats step S216. On the other hand, when determining that the intermediate container 91 is set at the discharge standby position P8, the control unit 50 controls the second conveying unit 14b if the weighing result received from the weighing device 80 matches the dispensing data. , the intermediate container 91 is transported from the discharge standby position P8 to the discharge position P9 (step S217). If an information processing device capable of reading the container-specific information of the intermediate container 91 set at the discharge standby position P8 is provided, the drug discharge unit 32 (discharge position P9) designated to be used in the packaging operation can , the intermediate container 91 can be properly transported. After that, the processing from step S218 to step S223 is performed. Since the processing from step S218 to step S223 is the same as that from step S207 to step S212 in FIG. 10, description thereof is omitted. In this embodiment, the control unit 50 controls the second transport unit 14b to transport the intermediate container 91 to the ejection position P9. ), the intermediate container 91 may be introduced into the drug packaging device 1 . In this case, if the container-specific information of the intermediate container 91 set at the discharge position P9 is read by an appropriate information processing device, whether or not the set destination is correct is determined based on the drug indicated by the drug information to which this container-specific information is assigned. You can check whether

External weighing is primarily performed using the external weighing container 92 . However, in the medicine packaging device 1 of the present embodiment, when the medicine is insufficient during weighing using the intermediate container 91, the intermediate container 91 can be used for external weighing. As a result, it is possible to divide and package medicines while responding to various situations on the spot. As a result, the flexibility of the drug packaging device 1 is enhanced.

Although the transfer of information via the information recording section 92e of the external weighing container 92 has been described above, the information recording section 91e of the intermediate container 91 also has the same configuration as the information recording section 92e. Therefore, the exchange of information between the medicine packaging device 1 and the weighing device 80 can be similarly realized via the intermediate container 91 .

Next, with reference to FIGS. 14 and 15, processing regarding the external weighing container 92 when performing the first operation will be described. FIG. 14 is a flow chart showing processing relating to the external weighing container 92 . FIG. 15 is an explanatory diagram showing the route of the external weighing container 92 when performing the processing of FIG.

When the external weighing support using the external weighing container 92 is selected in a state where the first operation is set by the preset processing or the like, the processing shown in FIG. 14 is performed.

First, the control unit 50 selects an external weighing container 92 to be transported from the external weighing containers 92 stored in the second storage unit 12 based on storage information and container unique information assigned to each drug indicated by the drug information. A weighing container 92 is determined. At this time, the third information processing section 20 updates the display content of the information display section 92d and the recorded content of the information recording section 92e for the selected external weighing container 92 (step S301). As a result, the dispensing data is displayed on the information display section 92d, and at least the dispensing data number and the information on the drug to be supplied to the external weighing container 92 among the drugs indicated by the drug information are recorded in the information recording section 92e. . The process of step S301 may be performed by the second information processing section 19 after the external weighing container 92 is transported to the weighing position P4 by the first transport section 14a.

Here, information such as the name of the drug to be weighed by the weighing device 80, the person taking the drug, and the target amount can be displayed on the information display section 92d. In addition, information indicating that the container has not been externally weighed may be displayed as the information regarding the dispensing. As a result, it is possible to prevent mistaking of the external measuring container 92, etc., and the operator or the like can easily visually understand which medicine should be measured and how much. Further, by reading the container-specific information recorded in the information recording unit 92e with an appropriate information processing device, it is possible to identify the external weighing container 92 assigned to which drug among the drugs indicated by the drug information. Therefore, it is possible to easily specify which drug should be put in the external weighing container 92 .

Next, the control section 50 controls the first transport section 14a to transport the external weighing container 92 from the second standby position P2 to the second take-out position P6 (step S302, (1) in FIG. 15).

The display contents of the information display section 92d and the recording contents of the information recording section 92e may be updated before the external weighing container 92 is taken out at the second take-out position P6. , or after being conveyed to the second take-out position P6. In this case, the information processing device may be provided in the first transport section 14a or the second take-out section 26. FIG. Further, the content displayed on the information display section 92d may be updated at the same time as the content recorded on the information recording section 92e is updated.

When the external measuring container 92 reaches the second take-out position P6, the operator takes out the external measuring container 92 from the second take-out position P6 to the outside of the drug packaging device 1, and removes the drug taken out from the drug bottle or the like into the external measuring container 92. , and weighed by the weighing device 80 .

The operator causes the information processing section 83 of the weighing device 80 to read the information recording section 92e of the external weighing container 92 taken out from the second take-out position P6. The weighing device 80 acquires the dispensing data number and container unique information from the information recording section 92e. The weighing device 80 acquires the corresponding dispensing data from the control unit 50 of the medicine packaging device 1 based on the information acquired from the information recording unit 92e, and displays the acquired dispensing data on the display unit 84. Next, the operator causes the information processing section 83 of the weighing device 80 to read the bar code (information recording section 71) of the medicine bottle or the like. Thereby, the control unit 81 of the weighing device 80 acquires the stored drug information. The control unit 81 collates the drug specified as the object to be weighed with the stored drug information to be acquired. If the verification results match, the operator weighs the drug using the weighing device 80 and supplies the weighed drug to the external weighing container 92 . After weighing the medicine, the weighing device 80 uses the control part 81 to send the weighing result including the measured amount of medicine together with the dispensing data acquired from the control unit 50 of the medicine packaging device 1 to the medicine packaging device 1 . Send to the control unit 50 . When the control unit 50 of the medicine packaging device 1 receives the weighing result and confirms that the weighing result received from the weighing device 80 matches the target amount of the dispensing data, it updates the dispensing data stored in the storage unit 61. do.

After the weighing of the drug by the weighing device 80 is finished, the measured amount (weighing result) may be displayed on the information display portion 92d of the information recording portion 92e of the external weighing container 92. FIG. In addition, the information display section 92d may display that the amount of medicine corresponding to the target amount is contained and preparation for introduction into the medicine packaging device 1 is completed.

Next, the control unit 50 determines whether or not the external weighing container 92 containing all doses of medicine is set at the discharge standby position P8 (step S303). When determining that the external weighing container 92 is not set at the discharge standby position P8, the control section 50 repeats step S303. On the other hand, when determining that the external weighing container 92 is set at the discharge standby position P8, the control unit 50 controls the second conveying unit 14b if the weighing result received from the weighing device 80 matches the dispensing data. Then, the external weighing container 92 is conveyed from the discharge standby position P8 to the discharge position P9 (step S304). If an information processing device capable of reading the container-specific information of the external weighing container 92 set at the discharge standby position P8 is provided, for the discharge unit (discharge position P9) designated to be used in the packaging operation, The external weighing container 92 can be suitably transported. Since the processing from step S305 to step S310 is the same as that from step S218 to step S223 in FIG. 12, description thereof is omitted.

As described above, in the present embodiment, the external measuring container 92 from which the drug has been measured by the weighing device 80 is first set at the discharge standby position P8, and then transported by the transporting section 14 (second transporting section 14b). , is attached to the container attachment portion 32a of the drug discharge portion 32 (steps S303 to S305).

FIG. It should be noted that the same applies to the case where the intermediate container 91 is used for external weighing (steps S216 to S208 in FIG. 12). Therefore, it is possible to ensure the accuracy of dispensing when performing external metering. The operator can directly attach the external weighing container 92 to the container attachment portion 32a. In this case, if the container-specific information of the external weighing container 92 set at the discharge position P9 is read by an appropriate information processing device, the drug indicated by the drug information to which this container-specific information is assigned can be used in the packaging operation. It is possible to confirm whether the external weighing container 92 is correctly set to the designated discharge portion (discharge position P9).

Next, mainly with reference to FIGS. 16 and 17, the processing related to the secondary container 93 when performing the second operation (that is, the operation of weighing the medicine but not packing it) will be described. FIG. 16 is a flow chart showing this process. FIG. 17 is a diagram showing the route of the secondary container 93 when performing the process of FIG. Note that steps S401 to S406 in FIG. 16 are similar to steps S201 to S206 in the process of FIG. 10, and therefore will be briefly described.

The second operation is performed when the second operation is set by a preset process or the like, as shown in step S105 of FIG. 7 or step S126 of FIG. First, the control unit 50 selects two containers to be transported from among the secondary containers 93 stored in the third storage unit 13 based on the storage information and the container-specific information assigned to each drug indicated by the drug information. A next container 93 is determined. At this time, the third information processing section 20 writes the dispensing data (including at least the dispensing data number) to the information recording section 93 e of the secondary container 93 . Then, the control section 50 controls the first conveying section 14a to convey the secondary container 93 from the third standby position P3 to the weighing position P4 (step S401 in FIG. 16, (1) in FIG. 17).
