From the viewpoint of the present invention, a drug distribution device having the following configuration is provided. That is, the drug distribution device includes a drug feeder, a measuring unit, a determination unit, and a distribution unit. The measuring unit measures the medicine charged into the medicine feeder. The determination unit determines whether or not there is an excess or deficiency of the drug in the drug feeder based on the weight of the drug weighed by the measuring unit. The distribution unit distributes the drug discharged by the drug feeder.

This makes it possible to confirm whether or not the amount of the drug charged into the drug feeder is appropriate.

In the drug distribution device, the determination unit has a first weighing value obtained by weighing the drug to be charged into the drug feeder with a measuring device before charging the drug feeder, and the measuring unit has a drug. It is preferable to determine whether or not there is an excess or deficiency of the drug in the drug feeder based on the second measured value obtained by weighing.

As a result, even if an excess or deficiency of the amount of the drug occurs for some reason after weighing with the measuring device, it can be detected.

In the drug distribution device, when the drug is weighed by the measuring device, the identification information of the measuring container in which the drug is housed and the information associating the first measuring value with the information, and the information from the measuring container to the drug feeder. It is preferable to obtain the first weighing value based on the reading result of the identification information of the measuring container read when the drug is charged.

Thereby, the first measurement value can be obtained by a reliable and simple method.

In the drug distribution device, when the determination unit determines that there is no excess or deficiency of the drug in the drug feeder, it is preferable to allow the drug to be discharged from the drug feeder to the distribution unit.

This makes it possible to distribute the drug after confirming that an appropriate amount of the drug has been charged into the drug feeder.

In the drug distribution device, when the determination unit determines that there is an excess or deficiency of the drug in the drug feeder, the discharge of the drug from the drug feeder to the distribution unit is prohibited, and the drug in the drug feeder is prohibited. It is preferable to notify that there is an excess or deficiency of the drug.

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a functional block diagram of the drug distribution device 31 of the present embodiment and the device related thereto.

FIG. 1 shows a measuring device 11, a measuring container 21, a drug distribution device 31, a drug packaging device 41, and a PC 51. These are installed, for example, in pharmacies or hospitals and are used to weigh and package drugs based on dispensing data. Further, the measuring device 11, the drug distributing device 31, the drug packaging device 41, and the PC 51 are connected by wire or wirelessly, and various data described later can be exchanged. In this embodiment, a powder (powder, fine granule, or granular drug) is treated as a drug. However, it may be configured to handle a drug other than a powder (for example, a tablet), may be configured to handle both a powder and a tablet, or may be configured to handle an excipient in addition to the drug. .. Further, in the following description, weighing means measuring the weight of an object.

The weighing device 11 is a device for weighing the medicine described in the dispensing data. Specifically, the drug is weighed by the weighing device 11 in a state of being contained in the measuring container 21. Further, the weighing device 11 has an input device (key, touch panel, etc.) (not shown), and can accept an operator's selection or the like. Further, the weighing device 11 has a storage device (flash memory or the like) shown in the figure, and can store various information (details will be described later). A display 12 and a bar code reader 13 are connected to the weighing device 11. The display 12 displays information output by the weighing device 11 (for example, a measured value, a name of a measured drug, information on dispensing data, etc.). The bar code reader 13 reads the bar code 22 attached to the measuring container 21 and outputs the reading result to the measuring device 11. The barcode 22 includes a container ID which is unique identification information attached to each measuring container 21.

The drug distribution device 31 distributes the drug measured by the measuring device 11 based on the dispensing data. The drug distribution device 31 includes a drug feeder 31a, a measurement unit 31b, a determination unit 31c, and a distribution unit 31d.

The drug weighed using the weighing device 11 is charged into the drug feeder 31a. The drug distribution device 31 of the present embodiment includes a plurality of drug feeders 31a, but may be configured to include one drug feeder 31a. The drug feeder 31a includes, for example, a storage unit for accommodating the charged drug and a discharge unit for discharging the drug contained in the storage unit to the distribution unit. The discharging unit includes, for example, a vibration motor, and discharges the drug to the distribution unit by vibrating the accommodating unit.

The measuring unit 31b weighs the medicine charged into the medicine feeder 31a. Specifically, the measuring unit 31b is arranged below the drug feeder 31a, and acquires the combined weight of the drug feeder 31a and the drug. Further, since the weight of the drug feeder 31a is predetermined, the weight of the drug charged into the drug feeder 31a can be obtained by subtracting the weight of the drug feeder 31a from the total weight. The weighing by the measuring unit 31b is mainly performed after the charging of the drug and before the discharging of the drug.

The determination unit 31c includes a calculation unit such as a CPU, and can perform various processes. In particular, the determination unit 31c determines whether or not the measurement value acquired by the measurement unit 31b is appropriate (whether or not there is an excess or deficiency of the drug in the drug feeder 31a).

The distribution unit 31d distributes the drug into each package and supplies the drug to the drug packaging device 41. The distribution unit 31d includes, for example, a distribution plate and a feeding unit. The drug discharged by the drug feeder 31a is spread on a distribution dish. The distribution dish makes the deposited drug uniform, for example, by rotating around the vertical direction as the center of rotation. The feeding unit scoops up the medicine on the distribution plate for each package and sends it to the medicine packaging device 41.

A display 32 and a barcode reader 33 are connected to the drug distribution device 31. The display 32 displays information output by the drug distribution device 31 (for example, a measured value, a name of the measured drug, a determination result of the determination unit 31c, information on dispensing data, etc.). The barcode reader 33 reads the barcode 22 attached to the measuring container 21 and outputs the reading result to the drug distribution device 31.

The drug packaging device 41 packages (packs) the drug sent from the distribution unit 31d of the drug distribution device 31 for each package. Specifically, a packaging material is set in the drug packaging device 41. The drug packaging device 41 puts a package of drug into the opening of the packaging material, and then welds the opening by heat or the like. By repeating this operation, the drug can be packaged.

The PC 51 includes an arithmetic unit such as a CPU, a storage device such as a hard disk or a solid state drive, and an input / output device. The arithmetic unit executes various processes by executing the program stored in the storage device. In the present embodiment, the PC 51 performs a process of storing and managing dispensing data input from the outside, and transmitting the dispensing data to the drug distribution device 31.

The configuration of the measuring device 11, the measuring container 21, the drug distribution device 31, and the drug packaging device 41 described above is an example, and may be different from the present embodiment. For example, an RFID reader may be used instead of the barcode readers 13 and 33, and an RFID tag may be used instead of the barcode 22. Further, the distribution unit 31d of the drug distribution device 31 is not limited to the configuration of scooping the drug, and may be configured to scrape out the drug and drop it.

Next, with reference to FIGS. 2 and 3, the flow of processing performed by the measuring device 11, the drug distributing device 31, the drug packaging device 41, and the PC 51 will be briefly described. FIG. 2 is a sequence diagram schematically showing the processing performed by these devices. FIG. 3 is a diagram showing the contents of dispensing data and measurement data.

As described above, the PC 51 stores dispensing data. The PC 51 transmits the dispensing data to be processed by the drug distribution device 31 to the drug distribution device 31 (S1). The drug distribution device 31 stores the received dispensing data as unprocessed dispensing data (dispensing data to be processed) (S2). The drug distribution device 31 transmits this dispensing data to the measuring device 11 (S3). The flow of transmitting and receiving dispensing data is an example, and for example, the PC 51 may transmit the dispensing data to both the measuring device 11 and the drug distributing device 31.

FIG. 3 shows the contents of the dispensing data. The dispensing data includes a data ID, a drug name, and a designated amount. The data ID is unique identification information attached to each dispensing data. In addition, a designated amount is registered for each drug name. In the example of FIG. 3, in order to dispense the drug with the data ID of XXX, it is necessary to put 10 g of the drug A and 20 g of the drug B into the drug distribution device 31. The item of dispensing data shown in FIG. 3 is an example, and other items (for example, a designated amount for each package) may be included.

Next, the operator supplies the medicine indicated by the dispensing data to the measuring container 21 according to the instruction of the measuring device 11. The weighing device 11 weighs the drug indicated by the dispensing data and creates the weighing data (S4). FIG. 3 shows the contents of the measurement data. The weighing data includes a data ID, a drug name, a first weighing value, and a container ID. The data ID and drug name are the same as the dispensing data. The first weighing value is a value obtained by weighing by the weighing device 11. Since the weighing device 11 measures each drug, the first weighing value is also described for each drug. The container ID is described for each drug and indicates the container in which the target drug is stored. The details of the processing of S4 will be described later. The weighing device 11 transmits this weighing data to the drug distribution device 31 (S5).

The drug distribution device 31 gives an instruction to the operator based on the measurement data received from the measurement device 11, and distributes the drug contained in the measurement container 21 (S6). The details of the processing of S6 will be described later.

The drug distribution device 31 sends the distributed drug to the drug packaging device 41. The drug packaging device 41 packages the drug sent from the drug distribution device 31 (S7).

Next, the details of the processing of S4 performed by the weighing device 11 will be described with reference to FIG. FIG. 4 is a flowchart of the weighing device 11.

After receiving the dispensing data from the drug distributing device 31, the measuring device 11 outputs the contents of the dispensing data to the display 12 (S101). This allows the worker to understand the dispensing to be performed.

Next, the weighing device 11 accepts the selection of the drug to be weighed (S102). Specifically, the measuring device 11 displays a list of drug names indicated by dispensing data on the display 12, and allows the operator to select a drug to start weighing. The operator operates the input device to select the drug to start weighing.

The weighing device 11 receives the container ID of the measuring container used for weighing (S103). Specifically, the weighing device 11 displays an instruction on the display 12 to read the barcode 22 of the measuring container 21 used for weighing with the barcode reader 13. When the operator reads the bar code 22 of the corresponding measuring container 21 with the bar code reader 13, the container ID of the measuring container 21 is input to the measuring device 11. The measuring device 11 stores the input container ID of the measuring container 21 in association with the drug (drug to be weighed) received in S102 (S104). Thereby, the drug contained in the measuring container 21 can be specified based on the container ID.

Next, the weighing device 11 weighs the medicine contained in the measuring container 21 and acquires the first weighing value (S105). The first measurement value is a value obtained by weighing the drug to be charged into the drug distribution device 31 by the measurement device 11 before charging the drug into the drug distribution device 31. During the weighing of the drug, the weighing device 11 displays the drug name, the first measured value, and the designated amount on the display 12. The operator supplies the drug from the drug container to the metering container 21 so that the first weighing value matches the specified amount of the dispensing data.

The weighing device 11 determines whether or not the first weighing value matches the specified amount of the dispensing data (S106). There are various criteria for this determination, but for example, in the weighing device 11, when the difference between the first weighing value and the specified amount is within the threshold value and the operator inputs that the supply of the drug has been completed. In addition, it is determined that the first weighing value matches the specified amount of the dispensing data. The weighing device 11 continues weighing the drug until it is determined that the first weighing value matches the specified amount in the dispensing data. When the weighing device 11 determines that the first weighing value matches the specified amount of the dispensing data, the weighing device 11 completes the weighing and stores the first weighing value (S107). As a result, the drug name of the target drug, the container ID of the measuring container 21 containing the target drug, and the first measurement value of the target drug are stored in the measuring device 11. In other words, the measurement data for the target drug will be stored.

Next, the measuring device 11 determines whether or not there is an unmeasured drug in the dispensing data (S108). For example, in the example of FIG. 3, when the drug A has been weighed and the drug B has not been weighed, the weighing device 11 determines that there is an unweighed drug. When the weighing device 11 determines that there is an unweighed drug, the unweighed drug is subjected to the processing after S102 again. For example, in S102, the measuring device 11 accepts selection of a drug that is a measurement target and has not been measured among the drugs included in the dispensing data.

By performing the processing of S102 to S107 for all the drugs described in the dispensing data, measurement data will be created. Then, when the weighing device 11 determines that there is no unmeasured drug in the dispensing data, the measuring device 11 transmits the weighing data to the drug distribution device 31 (S109).

Next, the details of the processing of S5 performed by the drug distribution device 31 will be described with reference to FIG. FIG. 5 is a flowchart of the drug distribution device 31.

As described with reference to FIG. 2, the drug distribution device 31 receives and stores the dispensing data from the PC 51 (S201), and transmits the dispensing data to the measuring device 11 (S202). Then, after the weighing is performed by the weighing device 11, the drug distribution device 31 receives and stores the weighing data from the weighing device 11 (S203).

Next, the drug distribution device 31 receives the container ID of the measuring container 21 to be charged (S204). Specifically, the drug distribution device 31 displays an instruction on the display 32 to read the bar code 22 of the measuring container 21 containing the drug to be charged by the bar code reader 33. When the operator reads the bar code 22 of the corresponding measuring container 21 with the bar code reader 33, the container ID of the measuring container 21 is input to the drug distribution device 31.

Next, the drug distribution device 31 selects and notifies the drug feeder 31a to which the drug contained in the measuring container 21 is to be charged (S205). Specifically, the drug distribution device 31 searches for the container ID input from the barcode reader 33 from the measurement data, and specifies the drug name, dispensing data, and the like corresponding to the container ID. Then, the drug distribution device 31 selects an appropriate drug feeder 31a based on the specified information. For example, when the drug A and the drug B are mixed in a distribution dish, the drug feeder 31a is selected so that the drug A and the drug B are discharged into the same distribution dish. The drug feeder 31a may be selected based on other criteria. The drug distribution device 31 notifies the drug feeder 31a to which the drug should be charged, for example, by lighting a lamp arranged in the vicinity of the drug feeder 31a. In addition, instead of or in addition to this kind of notification, information specifying the drug feeder 31a to which the drug should be added may be displayed on the display 32.

Next, the drug distribution device 31 weighs the drug charged into the drug feeder 31a using the measuring unit 31b and acquires a second weighing value (S206). The second measurement value is a value obtained by weighing the drug charged into the drug feeder 31a by the measurement unit 31b of the drug distribution device 31. As described above, the second weighing value is obtained by subtracting the weight of the drug feeder 31a from the weight indicated by the weighing unit 31b. Further, the second measurement value is performed before the discharge operation of discharging the drug to the distribution unit 31d (in other words, before vibrating the vibration motor for the discharge operation). As a result, the weighing is performed in a state where vibration is not generated, so that a highly accurate second weighing value can be obtained.

Next, the drug distribution device 31 determines whether or not the first measurement value and the second measurement value match (S207). Specifically, the drug distribution device 31 searches for the container ID acquired in S204 from the measurement data, and specifies the first measurement value corresponding to this container ID. When the difference between the first measurement value and the second measurement value is less than the threshold value, the drug distribution device 31 determines that the first measurement value and the second measurement value match. When the difference between the first measured value and the second measured value is equal to or greater than the threshold value, there is an excess or deficiency in the drug charged into the drug feeder 31a. The drug distribution device 31 may use a designated amount of dispensing data as a comparison target instead of the first measurement value. Specifically, the drug distribution device 31 determines whether or not there is an excess or deficiency in the drug charged into the drug feeder 31a based on whether or not the specified amount of the dispensing data and the second measurement value match. You may.

When the drug distribution device 31 determines that the first measurement value and the second measurement value match, the drug distribution device 31 permits the discharge of the drug from the drug feeder 31a to the distribution unit 31d (S208). After that, the drug is discharged from the drug feeder 31a to the distribution unit 31d unless the discharge is prohibited by another factor. As a result, not only the weighing is performed by the measuring device 11, but also the weighing is performed even after the drug is charged into the drug feeder 31a, so that the dispensing can be performed by a more reliable method.

After discharging the drug, the drug distribution device 31 again measures using the measuring unit 31b to acquire a third measured value (S209). The third measured value is a value obtained by measuring the substance in the drug feeder 31a using the measuring unit 31b after discharging the drug. The third weighing value is a value obtained by subtracting the weight of the drug feeder 31a from the weight indicated by the measuring unit 31b, similarly to the second weighing value. Therefore, if the drug is completely expelled, the third measure should be zero. The timing for acquiring the third measured value is, for example, after a series of discharge operations of the drug are completed. As a result, for example, when a vibration motor is used, the measurement can be performed after the vibration is stopped, so that an appropriate third measurement value can be easily obtained.

The drug distribution device 31 determines whether or not the third measurement value is less than the threshold value (S210). The threshold value used here is a value near zero. That is, the drug distribution device 31 determines whether or not all the drugs charged in the drug feeder 31a have been discharged. As the third weighing value, the weight indicated by the weighing unit 31b (weight including the drug feeder 31a) may be used. In this case, in S210, the drug distribution device 31 determines whether or not the difference between the third measured value and the weight of the drug feeder 31a is less than the threshold value.

When the drug distribution device 31 determines that the third measurement value is less than the threshold value, the drug distribution device 31 starts the distribution process by the distribution unit 31d (S212). Then, the drug distribution device 31 performs the same processing on the next drug included in the same dispensing data or the drug included in the next dispensing data to distribute the drug. This makes it possible to confirm whether or not the amount of the drug charged into the drug feeder 31a is appropriate. Therefore, for example, it is possible to detect a situation in which the weighing by the measuring device 11 is incorrect, the drug is dropped after the weighing by the measuring device 11, or the drug is increased or decreased after the weighing due to other circumstances, so that the reliability of the dispensing is improved. be able to.

When the drug distribution device 31 determines that the third measurement value is equal to or higher than the threshold value, the drug distribution device 31 restarts the discharge of the drug from the drug feeder 31a without performing the distribution process (S211). Then, after discharging the drug, the treatment of S210 is performed again. As a result, even if the drug remains in the drug feeder 31a, the distribution process can be performed after the remaining drug is discharged. In addition, for example, when the third metric value does not become less than the threshold value even after the processing of S211 is performed a predetermined number of times or more, the operator may be notified that an error has occurred.

Further, when the drug distribution device 31 determines in S207 that the first measurement value and the second measurement value do not match, the drug feeder 31 prohibits the discharge of the drug from the drug feeder 31a to the distribution unit 31d (S213). If the excess or deficiency of the drug is discharged to the distribution unit 31d, and the drug is re-weighed, the process of discarding the drug discharged to the distribution unit 31d or cleaning the distribution unit 31d is performed. May be needed. In this respect, by prohibiting the discharge to the distribution unit 31d when it is determined that there is an excess or deficiency, it is possible to omit the process of discarding the medicine discharged to the distribution unit 31d or cleaning the distribution unit 31d.

Next, the drug distribution device 31 notifies the operator that there is an excess or deficiency in the amount of the drug in the drug feeder 31a (S214). Examples of the notification method include generation of an error sound, lighting of a warning light, display on the display 32, and the like. Further, the drug distribution device 31 may display the degree of excess or deficiency (that is, the difference between the first measurement value and the second measurement value) on the display 32.

Next, the drug distribution device 31 accepts a choice as to whether or not to reweigh the drug (S215). Specifically, the drug distribution device 31 displays a check box for instructing reweighing, a check box for discharging as it is without reweighing, and the like on the display 32. The operator operates the input device, checks the desired check box, and confirms the check box to give an instruction to the drug distribution device 31.

The drug distribution device 31 determines whether or not a reweighing instruction has been given based on the operation of the operator (S216). When the drug distribution device 31 determines that reweighing has not been instructed (that is, when it is determined that the drug is instructed to be discharged as it is), the drug dispensing device 31 permits the drug to be discharged from the drug feeder 31a to the distribution unit 31d (S208). When the drug distribution device 31 determines that the reweighing is instructed, it resets the first weighing value of the weighing data, creates the reweighing dispensing data, and transmits it to the weighing device 11 (S217). The reweighing dispensing data is the same as the dispensing data except that the information indicating that the reweighing is performed is added. Further, when reweighing, the drug distribution device 31 discharges the drug charged in the drug feeder 31a into the measuring container 21 and cleans the drug feeder 31a as necessary. Then, reweighing is performed using the measuring container 21.

The weighing device 11 performs the process shown in the flowchart of FIG. 4 using the received reweighing dispensing data, and creates the weighing data again. In the following, the weighing data created based on the reweighing dispensing data will be referred to as reweighing data. The drug distribution device 31 again performs the process shown in the flowchart of FIG. 5 using the reweighing data received from the weighing device 11. As a result, if it is determined in the reweighing that the first weighing value and the second weighing value match, the distribution process is performed using an appropriate amount of the drug.

In the present embodiment, the first weighing value is reset in S217, but instead, the first weighing value may be overwritten when the reweighing data is received from the weighing device 11.

As described above, the drug distribution device 31 of the present embodiment includes a drug feeder 31a, a measurement unit 31b, a determination unit 31c, and a distribution unit 31d. The measuring unit 31b weighs the medicine charged into the medicine feeder 31a. The determination unit 31c determines whether or not there is an excess or deficiency of the agent in the agent feeder 31a based on the weight of the agent weighed by the measuring unit 31b. The distribution unit 31d distributes the drug discharged by the drug feeder 31a.

This makes it possible to confirm whether or not the amount of the drug charged into the drug feeder 31a is appropriate.

Further, in the drug distribution device 31 of the present embodiment, the determination unit 31c has the first weighing value obtained by weighing the drug to be charged into the drug feeder 31a by the measuring device 11 before charging the drug feeder 31a. , The presence or absence of excess or deficiency of the drug in the drug feeder 31a is determined based on the second measurement value obtained by weighing the drug by the measuring unit 31b.

As a result, even if an excess or deficiency of the amount of the drug occurs for some reason after the weighing by the measuring device 11, it can be detected.

Further, in the drug distribution device 31 of the present embodiment, information (measurement data) in which the identification information of the measuring container 21 containing the drug and the first measurement value are associated with each other when the drug is weighed by the measuring device 11 The first weighing value is acquired based on the reading result of the identification information (container ID) of the measuring container 21 read when the medicine is charged into the medicine feeder 31a from the measuring container 21.

Thereby, the first measurement value can be obtained by a reliable and simple method.

Further, in the drug distribution device 31 of the present embodiment, when the determination unit 31c determines that there is no excess or deficiency of the drug in the drug feeder 31a, the drug feeder 31a permits the discharge of the drug to the distribution unit 31d.

This makes it possible to distribute the drug after confirming that an appropriate amount of the drug has been charged into the drug feeder 31a.

Further, in the drug distribution device 31 of the present embodiment, when the determination unit 31c determines that there is an excess or deficiency of the drug in the drug feeder 31a, the discharge of the drug from the drug feeder 31a to the distribution unit 31d is prohibited, and the drug is prohibited. Notify that there is an excess or deficiency of the drug in the feeder 31a.

As a result, it is possible to prevent a situation in which distribution is performed in a state where there is an excess or deficiency in the drug in the drug feeder 31a, and it is possible to notify the operator that there is an excess or deficiency in the drug in the drug feeder 31a.

Further, in the drug distribution device 31 of the present embodiment, when the determination unit 31c determines that there is an excess or deficiency of the drug in the drug feeder 31a, the reweighing dispensing data is data for reweighing the drug in the measuring device 11. To create.

This makes it possible to facilitate the step of re-weighing with the weighing device 11.

Further, in the drug distribution device 31 of the present embodiment, the measuring unit 31b re-weighs after discharging the drug by the drug feeder 31a to acquire a third measured value. The determination unit 31c determines whether or not all the agents have been discharged from the agent feeder 31a based on the third measurement value.

As a result, it is possible to prevent a situation in which the drug is distributed while the drug remains in the drug feeder 31a.

Further, in the drug distribution device 31 of the present embodiment, when the determination unit 31c determines that all the drugs have not been discharged from the drug feeder 31a, the discharge of the drug from the drug feeder 31a to the distribution unit 31d is restarted.

As a result, even if the drug remains in the drug feeder 31a, the remaining drug can be automatically discharged to the distribution unit 31d.

Although the preferred embodiment of the present invention has been described above, the above configuration can be changed as follows, for example.

The flowchart shown in the above embodiment is an example, and some processes may be omitted, the contents of some processes may be changed, or new processes may be added. For example, in the flowchart of FIG. 4, the weighing data is transmitted from the weighing device 11 to the drug distribution device 31 at the timing when the weighing data is completed. Instead of this, the drug distribution device 31 may access the weighing device 11 at an appropriate timing to acquire weighing data. Further, in the flowchart of FIG. 5, after notifying in S214 that the amount of the drug in the drug feeder 31a is excessive or deficient, the drug distribution device 31 may be stopped to omit the process related to reweighing.

In the above embodiment, the display and the bar code reader are individually connected to the measuring device 11 and the drug distribution device 31, respectively. Instead of this, a common display or a common barcode reader may be used between the measuring device 11 and the drug distribution device 31.
