Description

The present invention relates to a drug dispensing device, and more particularly to a drug dispensing device provided with a distribution dish for distributing powder. The present invention also relates to a method of dispensing a drug.

In recent years, large hospitals and large-scale pharmacies have introduced powder dispensing devices and drug dispensing devices having a powder packaging function. Here, the powdered medicine packaging device is a device that individually packages each dose of powdered medicine based on prescription information. The powder packaging device can be used to automate most of the work of packaging powders in single doses.
The powder dispensing device 900 disclosed in Patent Document 1 is a device for individually packaging powders for each dose, and as shown in FIG. 14, a powder feeder 901, a powder dispensing device 902, and a drug packaging are provided inside. It has a device 903 and.
The powder feeder 901 has a hopper 905 and a trough 910. A piezoelectric element (not shown) is provided under the trough 910, and the trough 910 can be vibrated.

As shown in FIG. 14, the powder distribution device 902 is composed of a distribution plate 912 and a scraping device 915. The distribution dish 912 has a large opening in the center. Further, the distribution plate 912 is surrounded by a groove 916 having an arcuate cross section and an annular view in a plan view around the opening. The distribution pan 912 is rotatable by a motor 919. The distribution plate 912 can be continuously rotated at a constant rotation speed, or can be rotated only at a constant rotation angle.
The scraping device 915 is composed of an elevating arm whose tip moves up and down by rotating, and a scraping mechanism.
The scraping mechanism 915 has a disc-shaped scraping plate 917 that is rotated by a motor, and the scraping plate 918 is provided on the scraping plate 917.

The drug packaging device 903 is composed of a packaging hopper 920 and a packaging device 921 as shown in FIG.

Next, the procedure for packaging the powder using the powder packaging device 900 will be described.
The work of packaging the powder is performed by the pharmacist operating the powder packaging device 900 according to the doctor's prescription. That is, the pharmacist confirms the doctor's prescription and takes out the medicine bottle containing the prescribed powder from the medicine rack (not shown). Then, the total weight of the prescribed specific powder is weighed using a scale such as a balance. For example, if one dose is 3 g, and it is taken three times a day in the morning, noon, and night, and if it is taken for 7 days, 63 g of powdered medicine is weighed out.
Then, the weighed powder is charged into the hopper 905 of the powder feeder 901.
At the same time, the piezoelectric element (not shown) of the powder feeder 901 is energized to vibrate the trough 910, and the distribution pan 912 is continuously rotated at a constant rotation speed.
The powder charged into the hopper 905 falls from the opening at the lower end of the hopper 905 to the trough 910 of the powder feeder 901. Then, as the trough 910 vibrates, the powder slowly moves to the tip side and falls on the distribution plate 912.

On the other hand, since the distribution plate 912 is continuously rotating at a predetermined speed, the powder falling from the trough 910 is evenly distributed in the groove 916 of the distribution plate 912.

When the dropping of the powder onto the distribution plate 912 is completed, the rotation of the distribution plate 912 is stopped. Then, after that, the scraping plate 917 of the scraping device 915 is dropped into the groove 916 of the distribution plate 912. After that, the distribution plate 912 is rotated by an angle according to the number of distributions, and the powder for one dose is collected on the front side of the scraping plate 917. Then, the scraping plate 917 is rotated, and the powder is scraped out of the distribution plate 912 by the scraping plate 918 and put into the packaging hopper 920. The powder that has fallen from the packaging hopper 920 is packaged in the packaging device 921.

Further, Patent Document 2 discloses a method in which the prescription amount of powdered medicine can be input so as to be different depending on the time of administration, and the amount of powdered medicine contained in one package is changed.
In the method disclosed in Patent Document 2, when the distribution plate 912 is rotated and a single dose of powder is collected on the front side of the scraping plate 917, the amount of rotation (rotation angle) of the distribution plate 912 is prescribed. The amount of powder collected on the front side of the scraping plate 917 is changed according to the above.
According to the method disclosed in Patent Document 2, the powder can be packaged in response to an uneven prescription such as 1.2 g for morning dose, 1.2 g for lunch, and 2.4 g for evening. it can.

The conventional powder powder packaging device 900 is effective when the powder powder is divided into a large number and packaged. It is also preferably used when a single dose is large.
However, the conventional powdered medicine packaging device 900 is not good at packaging when the capacity of one dose (one package) is small and the number of packages such as two doses or three doses is small.
For example, a drug prescribed for pediatric use often contains 1 g or less of a drug for one dose, and it is not uncommon to give a very small amount of drug such as 0.3 g.
Also, it is difficult for doctors to choose the right drug because children cannot tell their doctor exactly what they are doing. Therefore, doctors often change the type and amount of prescription drug every day, observe the condition of pediatric patients, and select an appropriate drug.
In such a case, the doctor will change the prescription every day, and if the drug is to be taken three times, for example, morning, noon, and night, the doctor will give a prescription for three packets. The pharmacist then uses the powder packaging device 900 to prepare three packages of the drug according to the prescription.

In such a case, the total amount of the drug to be put into the distribution dish 912 is small. Therefore, when the powder is dropped from the trough 910 and the powder is evenly dispersed in the groove 916 of the distribution dish 912, the powder is only shallowly accumulated at the bottom of the groove 916.
Further, since the powdered medicine is evenly distributed over the entire circumference of the groove 916 of the distribution plate 912, in order to divide the powder into three doses, the distribution plate 912 is rotated by 1/3 turn to the front surface of the scraping plate 917. It is necessary to scrape the powder, and the rotation angle of the distribution plate 912 at the time of distribution is large.

As described above, when the powder is shallowly accumulated at the bottom of the groove 916 and the rotation angle of the distribution plate 912 at the time of scraping is large, the amount of the drug sticking to the bottom of the groove 916 cannot be ignored.
That is, the amount of the drug sticking to the bottom of the groove 916 is constant regardless of the depth of the drug accumulated in the groove 916. Therefore, the amount of loss of the drug when packaging the drug for one dose depends on the rotation angle of the distribution dish 912 at the time of scraping, and when the rotation angle of the distribution dish 912 at the time of scraping is large, one dose is taken. The amount of drug reduction is large.
Further, as described above, when the amount of the drug for one dose is small, the proportion of the drug remaining at the bottom of the groove 916 is relatively high. Therefore, if the amount of drug for one dose is small, there is a concern that the content of one packet may be less than the prescribed amount.

Further, according to the method disclosed in Patent Document 2, powdered medicine is applied in response to quantitative uneven prescriptions such as 1.2 g for morning dose, 1.2 g for lunch, and 2.4 g for evening. It can be packaged, but qualitative unequal formulations cannot be implemented. That is, in the method disclosed in Patent Document 2, powders X, Y, Z are enclosed in the package for the morning dose, only powder Z is enclosed in the package for the lunch, and powders X, Y are enclosed in the package for the evening dose. It is not possible to make packaging for three qualitative doses, such as being enclosed.

Therefore, the present invention pays attention to the above-mentioned problems of the prior art, and even when the content of one dose (one packet) is small and the number of divisions is small, an accurate amount can be contained in the package for one dose. It is an object of the present invention to provide a drug dispensing device and a drug dispensing method capable of containing the above-mentioned drugs.
Another object of the present invention is to provide a drug dispensing device and a drug dispensing method capable of dealing with quantitative unequal prescription and qualitative unequal prescription.

A mode for solving the above-mentioned problems includes a drug feeder for discharging powder, a distribution dish rotated by power, a scraping device for scraping out the powder charged in the distribution dish, and a drug packaging device. In the drug feeder, the powder is supplied from the drug feeder to the distribution dish, the powder on the distribution dish is scraped out by a scraping device and put into the drug packaging device, and the powder is packaged in each dose. Can monitor the amount of powder discharged and discharge the desired amount of powder, and feed the powder from the drug feeder to the distribution dish one by one, while stopping or rotating the distribution dish on the distribution dish. It is a drug dispensing device characterized in that it can be operated in a distributed arrangement mode in which powders are arranged at intervals for each dose.

In the drug dispensing device of this embodiment, powdered drug is supplied from the drug feeder to the distribution plate one by one. In the meantime, the rotation of the distribution plate is stopped or rotated at a very small angular velocity. Therefore, the powdered medicines are piled up like a mountain at one point or in a very narrow area, and a powdered medicine group is formed.
Although a plurality of powdered drug groups are generally formed, only one powdered drug group may be formed.
After that, the distribution dish is rotated to scrape the powder with the scraping device, and the powder is further scraped from the distribution dish. However, in the drug dispensing device of this embodiment, the rotation angle of the distribution dish when scraping the drug. Is small and the amount of drug remaining in the distribution dish is small. Therefore, the correct amount of drug is enclosed in one packet.

In the distributed arrangement mode, the rotation of the distribution dish is stopped when the powder is supplied from the drug feeder to the distribution dish, and when the drug feeder supplies the powder for one dose to the distribution dish, the drug feeder dispenses the powder to the distribution dish. It is desirable to temporarily stop the supply, then rotate the distribution pan by a predetermined angle, and then resume the supply of powder from the drug feeder to the distribution pan, and repeat this series of operations.

The drug feeder is composed of a drug container and a main body device. The drug container is removable from the main body device, the drug container has a drug discharge section for discharging the drug, and the main body device vibrates. It has a table, a vibrating means for vibrating the shaking table, a container holding means for temporarily fixing the drug container to the shaking table, and a weight measuring means for directly or indirectly measuring the weight of the drug container. The drug container is placed on a shaking table, the drug container is fixed to the shaking table by the container holding means, the shaking table is vibrated to discharge the powder little by little from the drug discharge part, and the amount of powder discharged is detected by the weight measuring means. It is desirable to be able to.

In the drug dispensing device of this embodiment, the drug container is fixed to the main body device. By vibrating the shaking table in this state, the whole or part of the drug container can be vibrated. Therefore, the drug in the drug container slowly moves to the drug discharge section side, the drug is rectified, the flow is laminarized, and the drug is discharged from the drug discharge section.
Further, since the container mounting device is equipped with a weight measuring means, it is possible to detect the discharge amount of the drug and automate the work of weighing out the powder or the like.

The original weight, which is the weight of the drug container before the drug is discharged, is measured by the weight measuring means, and the weight of the drug container is monitored by the weight measuring means when the powder is discharged little by little from the drug container. It is desirable to have a weighing function that stops the discharge of powder from the drug container when the current weight, which is the weight of the product, matches or substantially matches the value obtained by subtracting the target discharge amount from the original weight.

As for the means for measuring the weight of the drug container, the measurement of the weight of the drug container may be direct or indirect. That is, only the weight of the drug container may be directly measured, or the weight including the device such as the shaking table may be measured.
In the drug dispensing device of this embodiment, the original weight of the drug container before discharging the drug and the current weight of the drug container are utilized, and the current weight is the original weight minus the target discharge amount. When it matches, the vibration of the shaking table is stopped. Alternatively, in consideration of the weight of the drug in the middle of falling, the vibration of the shaking table is stopped when the current weight is slightly smaller than the value obtained by subtracting the target emission amount from the original weight and substantially matches. Therefore, after the target amount of the drug is discharged, the vibration of the shaking table is stopped and the discharge of the drug is stopped.

A container storage device is provided inside the drug dispensing device, and a container moving means is further provided. The container moving means takes out a predetermined drug container from the container storage device, places it on a shaking table, and disperses the drug from the drug container. The powder is discharged and put into the distribution plate, the powder charged in the distribution plate is scraped out by the scraping device and sent to the drug packaging area side, the drug is packaged by the drug packaging device, and the discharged drug container is discharged by the container moving means. It is desirable to be able to return it to the container storage device.

According to this aspect, a series of operations such as selection of a drug container, weighing, distribution, packaging, and returning the drug container to its original position can be automatically performed.

Further, an embodiment having the same function and effect has a distribution plate rotated by power, a scraping device for scraping out the powder charged in the distribution plate, and a drug packaging device, and supplies and distributes the powder to the distribution plate. In the drug dispensing device, which scrapes out the powder on the plate with a scraping device and puts it into the drug packaging device, and packages the powder for each dose, the powder is supplied to the distribution plate for each dose or for each dose, and is distributed between them. In a distributed arrangement mode, the dish is stopped or rotated to form one or more powder groups on the distribution dish, forming a spatial region on the distribution dish on both sides of the powder group in the circumferential direction where no powder is present. It is a drug dispensing device that can be operated and is characterized in that the powder group is scraped out by a scraping device and put into a drug packaging device.

Even in the drug dispensing device of this embodiment, powdered drugs can be piled up in a single point or in an extremely narrow area.
After that, the distribution dish is rotated to scrape the powder with the scraping device, and the powder is further scraped from the distribution dish. However, in the drug dispensing device of this embodiment, the rotation angle of the distribution dish when scraping the drug. Is small and the amount of drug remaining in the distribution dish is small. Therefore, the correct amount of drug is enclosed in one packet.

Having a cleaning device for cleaning the distribution dish, when cleaning the distribution dish with the cleaning device after operation in the distributed arrangement mode, at least the part or area where the powder was present may be cleaned. desirable.

According to this aspect, the distribution dish is cleaned to prevent drug contamination. It is also desirable that the cleaning performed after the operation in the distributed arrangement mode be performed with an emphasis on the site or area where the powder was present. For example, only the part or area where the powder was present is cleaned, or the time when the brush or the like is in contact with the part or area where the powder is present is set longer than that of other areas.

In the distributed arrangement mode, the amount of powder for one dose supplied to the distribution plate is individually changed, and different amounts of powder are mixed in the powder groups for one dose arranged on the distribution plate. It is desirable that it is possible.

This aspect is a drug dispensing device capable of dealing with quantitative uneven prescription.

In addition, it has a plurality of drug feeders, and one of the operations in the distributed arrangement mode is a mixed mode. In the mixed mode, the powder discharged from one drug feeder and the powder discharged from another drug feeder Is supplied to the same or adjacent locations on the distribution pan, and the powder discharged from one drug feeder and the powder discharged from another drug feeder are combined into one mixed drug group and scraped together with a scraping device. It may be a thing.

According to this aspect, a plurality of powders can be mixed in one package.

During that time, the weight of the drug container 2 is monitored, and when the total amount of powdered powder discharged reaches the desired weight, the vibration of the shaking table 20 is stopped.

After that, the rotation of the distribution plate 201 is stopped. Then, the scraping arm 605 is swung to lower the tip side to lower the scraping mechanism 606, and the scraping mechanism 606 is put into the drug charging groove 208 of the distribution pan 201.
Then, the distribution plate 201 is rotated by an angle corresponding to the number of distribution plates, and is scraped against the scraping plate 609. After that, the scraping plate 609 is rotated, the drug is scooped up by the scraping plate 607, discharged from the distribution plate 201, and charged into the drug charging opening 241.
The drug (powder) charged into the drug charging opening 241 drops the powder charging hopper 413, is carried to the drug packaging device 410, and is packaged in the drug packaging device 410.
This operation is sequentially repeated, all the chemicals in the distribution plate 201 are discharged, and each is packaged in the chemical packaging device 410.

When all the chemicals in the distribution plate 201 have been discharged, the groove cleaning operation is executed. That is, the cleaning arm of the cleaning device 500 is rotated to lower the cleaning brush 502 provided at the tip, and the cleaning brush 502 is put into the drug charging groove 208 of the distribution plate 201.
Then, while rotating the cleaning brush 502, the distribution plate 201 is rotated.
As a result, the residual drug remaining in the drug charging groove 208 of the distribution dish 201 is scraped off by the cleaning brush 502, and the soaring residual is sucked by the suction means. As a result, the inside of the drug charging groove 208 is cleaned.
In the groove cleaning operation performed after being operated in the even arrangement mode, the drug charging groove 208 of the distribution dish 201 is cleaned over the entire circumference.

In parallel with this, the container moving means 700 is activated, and the drug container 2 is returned to the container installation portion 103 of the drum member 102.

Next, the distributed arrangement mode, which is an operation peculiar to the present embodiment, will be described with reference to FIGS. 2, 3 and 4. Since the dispersion arrangement mode differs only in the step of adding the drug to the distribution dish 201, the description will focus on the differences, and the description of the common parts will be omitted.
When operating in the distributed arrangement mode, the distribution plate 201 is not rotated when the powder is dropped from the medicine container 2 onto the distribution plate 201.
That is, as shown in FIG. 2B, the powder is discharged from the drug container 2 to the distribution dish 201 with the distribution dish 201 stationary. More specifically, the drug container 2 is installed on the shaking table 20 of the container mounting device 3, and the shaking table 20 is vibrated.
Further, before and after the start of vibration, the weight of the drug container 2 is measured. During that time, the weight of the drug container 2 is monitored, and when the total amount of powder dropped reaches the weight of one dose, the vibration of the shaking table 20 is stopped.
That is, in the above-mentioned even arrangement mode, the total amount of powder for a plurality of doses is discharged from the drug container 2 at a time, but when operating in the distributed arrangement mode, only the powder for one dose is discharged from the medicine in the distribution dish 201. Drop it into the input groove 208.
Here, since the distribution plate 201 is kept stationary, the drop point of the powder does not change, and the drug (powder) 22 is laminated like a mountain at one point of the drug input groove 208 as shown in FIG. 2 (b). To do.

When the medicine for one dose has been dropped, the vibration of the shaking table 20 is stopped and the discharge of the powder is interrupted.
Then, the distribution plate 201 is slightly rotated. For example, it is rotated by an angle of about 5 to 30 degrees. That is, after rotating the distribution plate 201 by a minute angle, the rotation of the distribution plate 201 is stopped.
As a result, the pile of the powder 22 piled up earlier moves in the circumferential direction as shown in FIG. 2C, and a new groove surface of the distribution plate 201 wraps around directly under the medicine container 2.
Then, as shown in FIG. 3D, the vibration of the shaking table 20 is restarted, and only the powder 23 for one dose is dropped on the new groove surface of the new distribution plate 201.
Even in this case, since the distribution plate 201 is kept stationary, the drop point of the drug does not change, and the powder 23 is piled up like a pile at one point.

When the medicine for one dose has been dropped, the vibration of the shaking table 20 is stopped again, the discharge of the powder is interrupted, and the distribution plate 201 is slightly rotated. The pile of the powder 23 piled up earlier is moved in the circumferential direction so that the new groove surface of the distribution plate 201 wraps around directly under the medicine container 2.
Hereinafter, this step is repeated to form, for example, three piles of powder (powder group) 22, 23, 24 on the groove surface of the distribution plate 201 (FIG. 3e).
There is a gap between the powder groups as shown in the figure. Therefore, there is a spatial region 26 between the powder groups where no powder is present. Looking mainly at the powdered drug group, spatial regions 26 in which no powdered drug exists are formed on both sides of the powdered drug group in the circumferential direction.

After preparing a predetermined amount of powder group, the distribution dish 201 is rotated to rotate the first powder group (powder 22) in the vicinity of the scraping arm 605, and the tip side of the scraping arm 605 is lowered. The scraping mechanism 606 is lowered, and the scraping mechanism 606 is put into the drug charging groove 208 of the distribution dish 201.
Then, the distribution plate 201 is rotated so as not to reach the adjacent powder group (powder 23), and the first powder group (powder 22) is scraped up in front of the scraping plate 609.
Further, the scraping plate 609 is rotated, the drug is scooped up by the scraping plate 607, discharged from the distribution plate 201, and the powder 22 is charged into the drug charging opening 241.
The powder 22 charged into the drug charging opening 241 drops the powder charging hopper 413, is carried to the drug packaging device 410, and is packaged in the drug packaging device 410.
This operation is sequentially repeated, all the chemicals in the distribution plate 201 are discharged, and each is packaged in the chemical packaging device 410.
According to the distributed arrangement mode, since the rotation angle of the distribution plate 201 when attracting the medicine by the scraping plate 609 is small, the amount of the medicine sticking to the distribution plate 201 is small. Further, since the rotation angle of the distribution plate 201 is small, the time required to scrape out the drug is short.

When all the chemicals in the distribution plate 201 have been discharged, the groove cleaning operation is executed. However, in the groove cleaning operation performed after the operation in the distributed arrangement mode, only a part of the drug charging groove 208 of the distribution dish 201 is cleaned.
That is, in the case of the distributed arrangement mode, the powders 22, 23, and 24 are dropped only in a part of the area of the drug charging groove 208 of the distribution dish 201. For example, in the above-described embodiment, a group of three powders is formed on the groove surface of the distribution plate 201 (FIG. 3e). Here, the region where the powder group is distributed is about a quarter of the entire circumference of the groove, and is a region of about 90 degrees. Then, in the groove cleaning operation performed after being operated in the distributed arrangement mode, only the region of about 90 degrees and the portion in the vicinity thereof are cleaned.
Therefore, the time required for cleaning is greatly reduced.

In parallel with this, the container moving means 700 is activated, and the drug container 2 is returned to the container installation portion 103 of the drum member 102.

In the embodiment described above, when operating in the distributed arrangement mode, three powder groups are prepared and three doses are divided, but the number of divided packages is arbitrary and is one package. It may be 10 or more.

Further, in the embodiment described above, after the operation in the distributed arrangement mode, cleaning is performed only in the area where the drug (powder) is installed in the drug charging groove 208 of the distribution dish 201. That is, the cleaning process after operating in the distributed arrangement mode has been simplified. As a further simplified measure, only the part where the powder group was provided may be cleaned.
Of course, after operating in the distributed arrangement mode, the drug charging groove 208 may be cleaned over the entire circumference, but the area where the powder is installed or the part where the powder is installed is more careful than other areas or parts. It is recommended to clean it. For example, the rotation speed of the distribution plate 201 may be adjusted to lengthen the time for the cleaning brush 502 of the cleaning device 500 to stay in the area where the powder is installed or the portion where the powder is installed, or the distribution plate 201 may be reciprocated. It is conceivable that the number of times the cleaning brush 502 of the cleaning device 500 passes is increased as compared with other areas.

Further, the above-described embodiment is described on the premise that powdered drugs to be administered to the same patient are packaged, and the drug amounts of each powdered drug group are the same.
However, the present invention is not limited to this method of use, and drugs to be administered to a plurality of people may be packaged at the same time.
For example, as shown in FIG. 4, the first powder group (powder 27) was prescribed to a 3-year-old patient A, and the amount of the drug was 0.3 g. On the other hand, the second powder group (powder 28) was prescribed to a 6-year-old B patient, and the amount of the drug was 0.8 g.
When prescribing to multiple patients at the same time, the drug packaging device 410 on the downstream side has a print on the packaging bag that distinguishes the patient name and the time of administration, such as "for A patient" and "B patient". It is done and displayed so that the pharmacist does not make medication mistakes.

In addition, prescriptions prescribed with the same type of drug may be collected and powdered drugs for a plurality of people may be packaged at one time.

The drug dispensing device 1 of the present embodiment can also package the powder in response to a quantitative uneven prescription.
Since the situation in this case is the same as that in FIG. 4, a method for dealing with quantitative uneven prescription will be described in combination with FIG.
For example, when packaging powders for uneven prescriptions such as 1.2 grams for morning dose, 2.4 grams for lunch, and 1.2 grams for evening dose, the distribution plate 201 is in a stationary state. Then, 1.2 grams of the drug taken in the morning is discharged from the drug container 2 to the distribution plate 201. More specifically, the drug container 2 is installed on the shaking table 20 of the container mounting device 3, the shaking table 20 is vibrated and the weight of the drug container 2 is monitored, and the total amount of powdered powder dropped is 1 / morning dose. When the weight reaches 2 grams, the vibration of the shaking table 20 is stopped. The first powder group (powder 27) thus produced is a drug for morning use.

Then, after slightly rotating the distribution plate 201, the distribution plate 201 is stopped, and 2.4 grams of the medicine for lunch is discharged from the medicine container 2 to the distribution plate 201. That is, the time for vibrating the shaking table 20 and the like are different, and the amount of powder for one dose supplied from the medicine container 2 to the distribution plate is individually changed for each time of administration. The second powder group (powder 28) thus produced is a drug for lunch.
A powder group (not shown) for night use is prepared by the same process. As a result, different amounts of powdered drug groups are mixed in the distribution dish 201. The subsequent steps are as described above, and the powders 27 and 28 are sequentially charged into the drug charging opening 241 and packaged in the drug packaging device 410.
In the drug packaging device 410 on the downstream side, the packaging bag is printed on the packaging bag so as to distinguish the time of administration such as "morning dose" and "lunch dose".

In the above-described embodiment, the case where one type of powder is enclosed in the package for one dose has been described as an example, but a plurality of types of powder may be enclosed in the package for one dose.
When a plurality of types of powders are enclosed in the package for one dose, the drug dispensing device 1 is operated in the mixing mode. The mixed mode is a form of the distributed arrangement mode.
Hereinafter, the mixed mode will be described with reference to FIGS. 10 to 13.
For convenience of explanation, the distribution plate 201 is virtually divided into A area, B area, and C area. Further, in the present embodiment, three container mounting devices 3 are used, and the drug container 2 is installed in each container mounting device 3. For convenience of explanation, the three drug containers 2 are distinguished as drug containers 2x, 2y, and 2z. Different powders are stored in each drug container 2x, 2y, 2z. For ease of understanding, the powder X contained in the drug container 2x is indicated by a diagonal line that inclines from the upper left to the lower right, and the powder Y contained in the drug container 2y is inclined from the upper right to the lower left. It is indicated by a diagonal line, and the powder X contained in the drug container 2z is indicated by a blank frame.

FIG. 10 shows an example in which three packages, one for morning, one for lunch, and one for night, are packaged, and the amount of powder X in each package is the same. The amount of powder Y in each package is also the same. Furthermore, the amount of powder Z in each package is the same. For convenience of illustration, the amounts of powder X, powder Y, and powder Z in each package are shown as if they were the same, but in reality these amounts are different.
In this case, as shown in the stage (1) of FIG. 10, the distribution plate 201 is rotated so that the area A of the distribution plate 201 comes to the position directly below the drug container 2z, and the rotation of the distribution plate 201 is stopped at this position. To do.
Then, with the distribution dish 201 stationary, the drug Z is discharged from the drug container 2z to the distribution dish 201. More specifically, the shaking table 20 of the container mounting device 3 in which the drug container 2z is installed is vibrated.
Further, before and after the start of vibration, the weight of the drug container 2z is measured. During that time, the weight of the drug container 2z is monitored, and when the total amount of powder Z dropped reaches the weight of one dose, the vibration of the shaking table 20 is stopped.

Then, the distribution plate 201 is slightly rotated, and the B area of the distribution plate 201 is located directly below the drug container 2z as shown in the stage (2) of FIG. 10, and the distribution plate 201 is located directly below the drug container 2y. The rotation of the distribution plate 201 is stopped in the presence of the A area of the above.
Then, with the distribution dish 201 stationary, the drug Z and the drug Y are discharged from the drug container 2y and the drug container 2z to the distribution dish 201.
As a result, the drug Y dropped from the drug container 2y is stacked on the drug Z dropped in the previous step in the A area.
Further, the medicine Z falls from the medicine container 2z into the B area of the distribution plate 201.

Then, the distribution plate 201 is further rotated slightly, and the C area of the distribution plate 201 is located directly below the drug container 2z as shown in the stage (3) of FIG. 10, and the distribution plate 201 is located directly below the drug container 2y. The rotation of the distribution plate 201 is stopped while the B area of 201 is present and the A area of the distribution plate 201 is located directly below the drug container 2x.
Then, with the distribution dish 201 stationary, the drug Z, the drug Y, and the drug X are discharged from the drug container 2x, the drug container 2y, and the drug container 2z into the distribution dish 201.
As a result, the drug X dropped from the drug container 2x is further stacked on the drugs Z and Y dropped in the previous step in the A area.
Further, in the B area, the drug Y dropped from the drug container 2y is stacked on the drug Z dropped in the previous step.
Further, the drug Z falls from the drug container 2z into the C area of the distribution dish 201.

Then, the distribution plate 201 is further rotated slightly, and as shown in the stage (4) of FIG. 10, there is no area A, B, or C of the distribution plate 201 at the position directly below the drug container 2z, and the drug container is not provided. The rotation of the distribution plate 201 is stopped in a state where the C area of the distribution plate 201 is located directly below 2y and the B area of the distribution plate 201 is located directly below the drug container 2x.
Area A is separated from each drug container 2x.
Then, with the distribution dish 201 stationary, the drug Y and the drug X are discharged from the drug container 2x and the drug container 2y to the distribution dish 201.
As a result, in the B area, the medicine X dropped from the medicine container 2x is further piled up on the medicines Z and Y dropped in the previous step.
Further, in the C area, the drug Y dropped from the drug container 2y is stacked on the drug Z dropped in the previous step.

Then, the distribution plate 201 is further rotated slightly, and there is no area of A, B, or C of the distribution plate 201 at the position directly below the drug containers 2z and 2y as shown in the stage (5) of FIG. The rotation of the distribution plate 201 is stopped while the C area of the distribution plate 201 is located directly below the drug container 2x.
Further, the A area and the B area are separated from each drug container 2x.
Then, with the distribution dish 201 stationary, the drug X is discharged from the drug container 2x to the distribution dish 201.
As a result, the drug X dropped from the drug container 2x is further stacked on the drugs Z and Y dropped in the previous step in the C area.
In this way, mixed drug groups 31, 32, 33 in which powders X, Y, and Z are stacked are formed in the A area, B area, and C area of the distribution dish 201, respectively.
The subsequent step is the same as the operation of the above-mentioned normal distributed arrangement mode, in which the distribution pan 201 is rotated to scrape the first mixed drug groups 31, 32, 33 one by one, and the scraping plate 609 is rotated. , The drug is scooped up by the scraping plate 607 and discharged from the distribution plate 201, each drug group is charged into the drug charging opening 241 and packaged by the drug packaging device 410.

In the embodiment described above, the case where the powders X, Y, and Z are enclosed in the same amount in each package is shown, but the contents of the package can be changed individually. That is, the drug dispensing device 1 of the present embodiment can also package the powder in response to a qualitative uneven prescription.
For example, the package for the morning dose contains powders X, Y, Z, the package for lunch contains only powder Z, and the package for night use contains powders X, Y. You can also make it.
For example, the mixed drug groups 35, 36, and 37 are prepared by using area A as a morning dose, area B as a lunch dose, and area C as a night dose.
In this case, as shown in FIG. 11, in the stage (3), the drug drop from the drug containers 2y and 2z is omitted to prevent the drug Y from falling into the B area (for lunch), and the C area (for lunch). Prevents the drug Z from falling into the night dose). Further, in the stage (4), the drug X is omitted from the drug container 2x to prevent the drug X from falling into the B area (for lunch).
As a result, a mixed drug group 35 containing powders X, Y, and Z is formed in the A area, and a drug group 36 containing only the powder Z is formed in the B area. Further, a mixed drug group 37 of powders X and Y is formed in the C area.
The subsequent steps are the same as the operation of the normal distributed arrangement mode described above.

It is also possible to individually change the amount of drug contained in the package.
For example, powders X, Y, and Z are all encapsulated in the daily dose, but the amount of powder Y prescribed may be larger than the others in the lunch dose. .. That is, it is possible to enclose a plurality of types of powdered medicines and further package the powdered medicines in response to a quantitative uneven prescription.
In this case, the amount of the drug dropped from the drug container 2y is increased in the stage (3) as shown in FIG. As a result, mixed drug groups 45, 46, 47 in which powders X, Y, and Z are stacked are formed in the A area, B area, and C area of the distribution dish 201, respectively, but the B area is compared with the other areas. A large amount of powder Y is piled up.
The subsequent steps are the same as the operation of the normal distributed arrangement mode described above.

In each of the examples shown in FIGS. 10 to 12, the method of rotating the distribution plate 201 in the same direction to perform packaging is disclosed, but the distribution plate 201 is rotated in both forward and reverse directions to form a mixed drug group. You may.
FIG. 13 shows an embodiment in which the distribution dish 201 is rotated in both forward and reverse directions to form a mixed drug group.
In this case, in the stage (1) of FIG. 13, the A area of the distribution dish 201 is located directly below the drug container 2x, the B area of the distribution dish 201 is located directly below the drug container 2y, and the drug container 2z is located. It is assumed that the C area of the distribution plate 201 is located directly below.
Then, the powder is dropped from each drug container 2x, 2y, 2z at the same time. As a result, powder X falls in area A, powder Y falls in area B, and powder Z falls in area C.

Then, the distribution plate 201 is rotated slightly in the positive direction, and the B area of the distribution plate 201 is located directly below the drug container 2x as shown in the stage (2) of FIG. 13, and is located directly below the drug container 2y. It is assumed that there is a C area of the distribution plate 201, and there is no area directly below the drug container 2z.
Then, the powder is dropped from each of the drug containers 2x and 2y at the same time. As a result, the drug X dropped from the drug container 2x is stacked on the drug Y dropped in the previous step in the B area. Further, in the C area, the drug Y dropped from the drug container 2y is stacked on the drug z dropped in the previous step.

Then, the distribution plate 201 is further slightly rotated in the positive direction so that the C area of the distribution plate 201 is located at a position directly below the drug container 2x as shown in the stage (3) of FIG.
Then, the powder is dropped from the drug container 2x. As a result, in the C area, the medicine X dropped from the medicine container 2x is piled up on the medicines Z and Y dropped in the previous step.

Then, the distribution plate 201 is rotated in the slightly opposite direction, and as shown in the stage (4) of FIG. 13, the A area of the distribution plate 201 is located directly below the drug container 2y, and the position directly below the drug container 2z. The rotation of the distribution plate 201 is stopped while the B area of the distribution plate 201 is present in the distribution plate 201.
Then, with the distribution dish 201 stationary, the drugs Y and Z are discharged from the drug container 2y and the drug container 2z to the distribution dish 201.
As a result, in the B area, the medicine Z dropped from the medicine container 2z is piled up on the medicines Y and X dropped in the previous step. Further, in the area A, the drug Y dropped from the drug container 2y is stacked on the drug X dropped in the previous step.

Then, the distribution plate 201 is further rotated in the slightly opposite direction, and the distribution plate 201 is rotated with the A area of the distribution plate 201 at a position directly below the drug container 2z as shown in the stage (5) of FIG. Stop.
Then, with the distribution dish 201 stationary, the drug Z is discharged from the drug container 2z to the distribution dish 201.
As a result, the drug Z dropped from the drug container 2z is stacked on the drugs X and Y dropped in the previous step in the A area.
In this way, mixed drug groups 55, 56, 57 in which powders X, Y, and Z are stacked are formed in the A area, B area, and C area of the distribution dish 201, respectively.
The subsequent steps are the same as the operation of the normal distributed arrangement mode described above.

Also in the embodiment described above, three mixed powder groups were prepared and divided into three doses, but the number of divided packages is arbitrary and may be one divided group. There may be.
Further, in the embodiment described above, in the same area, the newly dropped drug is stacked on the previously dropped drug, but it is not essential to stack the drugs, and the drugs are grouped together in a close area. Just drop it.
That is, in the dispersed arrangement mode (including the mixed mode), the distribution plate 201 is rotated and the chemicals are attracted by the scraping plate 609. Therefore, as long as a plurality of types of chemicals are gathered in a close region. , Multiple drugs can be scraped together and scraped out together.

In the above-described embodiment, a set of drug feeders 5 is configured by the container mounting device 3 and the drug container 2, and a configuration is adopted in which the amount of powdered powder dropped is monitored. However, the present invention is not limited to this configuration, and for example, as shown in the prior art, a powder feeder 906 having a structure in which a piezoelectric element (not shown) is provided under the trough 910 to vibrate the trough 910 is provided. It can also be used.
In this case, the pharmacist weighs a predetermined amount of powder, puts the powder into the hopper 905, and drops it into the distribution plate 912.

Further, as a problem to be solved by the present invention, there is a concern that the amount of the drug dropped becomes unstable when operating in the distributed arrangement mode.
That is, in the present invention, when operating in the distributed arrangement mode, the container mounting device 3 is vibrated to discharge the drug from the drug container 2, and when the discharge of a predetermined amount is completed, the vibration of the container mounting device 3 is stopped. After a certain period of time has elapsed, the container placing device 3 is vibrated to discharge the drug from the drug container 2.
Considering the behavior of the drug in the drug container 2 here, since the drug container 2 is stored in the vertical position, the drugs inside are gathered at the bottom portion based on the vertical position, and are collected from the drug discharge port. Is far away.
Then, when the container mounting device 3 starts to vibrate, the internal drug slowly advances toward the drug discharge port as shown in FIG. 6, and finally falls from the drug discharge unit 8. The drug is then acclimatized in layers as it advances.
However, at the time of the second discharge, the leading portion of the drug has already reached the drug discharge section 8. Therefore, the discharge conditions are different between the first discharge and the second and subsequent discharges.

As a means for solving this problem, it is conceivable to change the vibration pattern to operate the container mounting device 3 and temporarily move the drug to the bottom portion when starting the second and subsequent discharges.
Further, when starting the second and subsequent discharges, the hand portion 707 of the container moving means 700 holds the drug container 2 and temporarily puts it in a vertical posture, or tilts the drug discharge section 8 upward and then tilts the drug. The container 2 may be reattached. By going through this step, the leading portion of the drug is retracted, and the drug can be discharged under the same discharge conditions from the second time onward, and a highly accurate dispersed arrangement can be realized.

In the above-described embodiment, when the medicine is charged from the medicine container 2 into the distribution plate 201 in the dispersion arrangement mode, the rotation of the distribution plate 201 is stopped, but the medicine is charged while rotating the distribution plate 201 at a low speed. You may put it in.
