Description

  The present invention relates to a consumable management server, method, and program for managing chemicals and the like contained in a container attached with an RFID using a single weighing scale and a single RFID reader.

Consider the management of containers (bottles / boxes) containing consumables such as medicines, spices, and radioactive materials. Here, chemicals will be described as an example.
Since there are a wide variety of chemicals and some of them are harmful, it is necessary to strictly control the taking-out and bringing-in of chemicals. In recent years, a method for managing medicine by attaching an RFID tag to a medicine container and reading it with an RFID reader has been developed.
However, with the conventional technology, although it is possible to manage containers such as bottles and boxes, it was not possible to manage how much of the medicines and tablets contained therein were used. In order to manage the amount of use, it is necessary for the user to record the amount of use manually.

Some have aimed to manage the amount of chemicals used on a container basis (see Patent Document 1 and Patent Document 2), but a device for detecting the remaining amount of the object must be attached to each container. There was no way to detect when, how and how much the drug was used, only by detecting whether the amount was above or below the threshold.

In addition, according to the present invention, when the above data is used and a consumable is used in a predetermined amount or more, an effect of issuing a warning is obtained.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic diagram showing the configuration of a consumables management server according to an embodiment of the present invention and a functional block diagram thereof.
Hereinafter, parts corresponding to the same parts are denoted by the same reference numerals, and description thereof is omitted.

First, a schematic diagram showing the configuration is shown using the upper part of FIG.
The plurality of medicine containers 4 are provided with RFID tags. A tag ID for identifying a chemical container is added to the RFID tag, and each tag ID is read by a chemical table 2 with an RFID reader, which will be described later. For example, an RFID tag is attached to the bottom of the chemical container 4. The reason why the RFID tag is attached to the bottom is to make it easier to read out the RFID tag than the chemical table 2 with an RFID reader described later.
The medicine table 2 with the RFID reader reads each tag ID from the medicine container 4 to which the RFID tag is attached at regular intervals and transmits it to the management server 3. For example, the medicine table 2 with an RFID reader is a table for placing a plurality of medicines.
The weigh scale 1 reads the total weight of the plurality of medicine containers 4 at regular intervals, and transmits this to the management server 3. The weighing scale 1 measures, for example, the total weight of a plurality of medicine containers 4 and a medicine table 2 with an RFID reader on which the plurality of medicine containers 4 are placed. The weighing scale 1 measures the weight of the medicine container and the weight of the contents medicine contained in the container.
The management server 3 receives the tag ID of the medicine container 4 from the medicine table 2 with the RFID reader, receives the total weight of the medicine container 4 from the scale 1, and receives the medicine by the received tag ID and the total weight. to manage. For example, the management server 3 alternately receives information transmitted from the medicine table 2 with the RFID reader and information transmitted from the weighing scale 1.
In addition, since the chemical | medical agent used as the object demonstrated here is the chemical | medical agent contained in the container and it measures as a weight, the chemical | medical agent itself may be solid or liquid.

Next, each functional block diagram will be described using the lower part of FIG. The chemical table 2 with an RFID reader has an RFID tag reading function unit 21. The RFID tag reading function unit 21 periodically reads information on the RFID tag attached to the medicine container placed on the medicine table, and transmits the tag ID information to the tag increase / decrease detection function unit 31.
The weight scale 1 has a mass detection function unit 11. The mass detection function unit 11 periodically measures the total weight of the medicine placed on the medicine table, and transmits the total weight information to the mass increase / decrease detection function unit 32.

The management server 3 includes a tag increase / decrease detection function unit 31, a mass increase / decrease detection function unit 32, and a drug increase / decrease recording function unit 33, and also includes a drug-tag association DB1 and a drug management DB2.
The tag increase / decrease detection function unit 31 receives information from the RFID tag reading function unit 21, detects a difference from the previous tag ID information, and transmits the information to the drug increase / decrease recording function unit 33.
The tag increase / decrease detection function unit 31 detects the difference from the previous information. The tag increase / decrease detection function unit 31 has a storage unit that stores the previous information, and is stored in the storage unit. The previous tag ID information and the tag ID information received from the RFID tag reading function unit 21 are compared. If there is a difference, the previous tag ID information stored in the storage unit and the RFID tag reading function unit 21 are compared. This is done by detecting an ID having a difference in tag ID information received from.

The mass increase / decrease detection function unit 32 receives information from the mass detection function unit 11, detects a difference (mass increase / decrease) from the previous information, and transmits the information to the drug increase / decrease recording function unit 33.
The detection of the difference from the previous information performed in the mass increase / decrease detection function unit 32 includes a storage unit that is a memory for the mass increase / decrease detection function unit 32 to store the previous information, and is stored in the storage unit. The previous weight information and the weight information received from the mass detection function unit 11 are compared. If there is a difference, the difference between the weight received from the mass detection function unit 11 and the previous weight stored in the storage unit This is done by calculating

The drug increase / decrease recording function unit 33 refers to the information in the drug-tag association DB 1 based on the information received from the tag increase / decrease detection function unit 31 and the mass increase / decrease detection function unit 32, and which drug is used when and how much. Calculate whether it has been used and record it in the medicine management DB 2.
The medicine-tag association DB 1 is a DB for registering information for associating a medicine with a tag ID attached to the medicine container. The medicine management DB 2 is a DB that stores which medicine is used when and how much.
The management server 3 also has a current time detection function unit that can obtain the current time such as a real time clock (RTC).

Next, FIG. 2 shows an example of the contents of the medicine-tag association DB 1 and the medicine management DB 2. The upper part of FIG. 2 shows the contents as an example of the medicine-tag association DB 1. The medicine-tag association DB 1 is a DB that associates medicine names with tag IDs attached thereto. As a correspondence table in which tag IDs and medicine names correspond one-to-one, they are stored in the medicine-tag correspondence DB 1.
Further, the tag ID is unique, and by specifying the tag ID, the drug name corresponding to the specified tag ID is uniquely selected. The correspondence between the tag ID and the medicine name is input in advance by a human hand and registered in the medicine-tag correspondence DB 1.

In the lower part of FIG. 2, contents as an example of the medicine management DB 2 are shown. The medicine management DB 2 stores a medicine name, take-out time, take-out amount, return time, return amount and use amount.
These are automatically added and updated by the medicine increase / decrease recording function unit 3 as will be described later.

Next, the entire process will be described with reference to FIG. First, the association between the medicine and the ID of the RFID tag attached to the medicine container is registered in advance in the medicine-tag association DB 1 (step S301). Next, the RFID tag reading function unit 21 periodically scans all of the RFID tags placed on the chemical table from the chemical table 2 with the RFID reader, and transmits the information to the tag increase / decrease detection function unit 31. (Step S302). The mass detection function unit 11 periodically scans the total weight of the drug containers placed on the drug table from the weigh scale 1 and transmits the information to the mass increase / decrease detection function unit 32 (step S303). .
If there is no change in the RFID tag as determined by the tag increase / decrease detection function unit 31 and there is no increase / decrease in mass as determined by the mass increase / decrease detection function unit 32, steps S302 and S303 are repeated.
Next, if there is a change in the RFID tag, the tag increase / decrease detection function unit 31 sends the changed tag ID difference information (change type and changed RFID tag tag ID information) to the drug increase / decrease recording function unit 33. Transmit (step S304). This is because the tag ID information received last time is stored in the storage unit as the previous tag ID information, compared with the received tag ID information, and if it is different (if there is a change), the tag with a different tag ID This is done by detecting the ID difference information and transmitting the tag ID difference information.
Similarly, when there is an increase / decrease in mass, the mass increase / decrease detection function unit 32 transmits the mass increase / decrease information (information on the value of the increased / decreased mass) to the medicine increase / decrease recording function unit 33 (step S305). This is performed by holding the weight information received last time, detecting the weight increase / decrease information as the weight increase / decrease information by taking the difference from the received weight information, and transmitting the weight increase / decrease information.
The drug increase / decrease recording function unit 33 acquires the drug name from the drug-tag association DB 1 based on the RFID tag difference information received from the tag increase / decrease detection function unit 31 and the mass increase / decrease information received from the mass increase / decrease detection function unit 32. (Step S305), “medicine name”, “increase / decrease type”, “weight”, and “measurement time” are registered in the medicine management DB 2 (step S307). There are three types of “increase / decrease types” registered here: “take-out”, “return”, and “new”, as will be described later. The measurement time is the current time obtained from the current time detection function.

Next, processing performed in the tag increase / decrease detection function unit 31 will be described with reference to the flowchart of FIG. First, information is received from the RFID tag reading function unit 21 (step S41). Next, the new information received from the RFID tag reading function unit 21 is compared with the information recorded in the memory to determine whether there is a difference (step S42). Here, the information stored in the memory is information recorded in the memory in step S44 described later.
If it is determined that there is no difference in the determination result in step S42, information is received again from the RFID tag reading function unit 21 (step S41).
If it is determined that there is a difference in the determination result of step S42, the difference and the increase / decrease type are transmitted to the medicine increase / decrease recording function unit 33 (step S43). For example, when there is no information stored in the memory and the new information received from the RFID tag reading function unit 21 is ID001, the difference is “ID001” and the type is “increase”.
Next, the new information received from the RFID tag reading function unit 21 is recorded in the memory (step S44). Thereafter, information is received again from the RFID tag reading function unit 21 (step S41).

Next, processing performed in the mass increase / decrease detection function unit 32 will be described with reference to the flowchart of FIG. First, information is received from the mass detection function unit 11 (step S51). Next, it is determined whether the new information received from the mass detection function unit 11 is different from the information recorded in the memory (step S52). Here, the information stored in the memory is information recorded in the memory in step S54 described later.
If the determination result in step S52 is not different, information is received again from the mass detection function unit 11 (step S51).
If there is a difference in the determination result in step S52, the difference and the increase / decrease type are transmitted to the medicine increase / decrease recording function unit 33 (step S53). For example, when the information stored in the memory is 103.5 g and the new information received from the RFID tag reading function unit 21 is 185.5 g, the difference is “82.0 g” and the type is “increase” " On the other hand, for example, when the information stored in the memory is 180.5 g and the new information received from the RFID tag reading function unit 21 is 160.5 g, the difference is “20.0 g” and the type is “Decrease”.
Next, the new information received from the mass detection function unit 11 is recorded in the memory (step S54). Thereafter, information is received again from the mass detection function unit 11 (step S51).

  Next, processing performed in the medicine increase / decrease recording function unit 33 will be described with reference to the flowchart of FIG. First, information transmitted from the tag increase / decrease detection function unit 31 is received (step S901). Next, the corresponding medicine name is acquired from the medicine-tag association DB 1 (step S902). Next, the information transmitted from the mass detection function unit 32 is received (step S903). Next, it is determined whether the tag increase / decrease type is “increase” or “decrease” (step S904).

If the determination result in step S904 is “increase”, it is next determined from the medicine management DB 2 whether or not there is a row corresponding to the medicine (step S906). If it exists, it is determined as “return”, and is added as return information in the blank of the medicine management DB 2 (step S907). Then, it repeats from step S901.
For example, it is assumed that there is a data row for the medicine name “XX pharmaceutical” in L71 as in the contents of the medicine management DB 2 shown in FIG. In L71, the return time, return amount, and use amount fields are blank.
Here, if the increase / decrease type is "Increase", the drug name is "XX Pharmaceutical", and the return time / return amount / use amount in the line corresponding to the drug name is blank, information on the return time and return amount Write and also calculate “amount taken-amount returned” and register it as a usage amount. As a result, as in L72, the return time, return amount and usage amount columns are registered.

If the determination result in step S906 does not exist, it is determined as “new”, a new line is added to the medicine management DB 2 and only return information is recorded (step S908). Then, it repeats from step S901.
For example, in the state where only L81 is registered as shown in the upper part of FIG. 8, if the increase / decrease type is “increase” and there is no line corresponding to the drug name, information is written in the return time and return amount, Register the field as "-". As a result, as shown in the lower part of FIG. 8, in addition to the previously registered L81, L82 is newly registered.
As described above, the medicine management DB 2 is added and registered with a history of the use of medicines.

If the determination result in step S904 is “decrease”, it is determined to be “take-out”, and a new line is added to the medicine management DB 2 to record only take-out information. Then, it repeats from step S901.
For example, when only the L91 is registered as shown in the upper part of FIG. 9 and the increase / decrease type is “decrease”, a new line is created and registered in the medicine name, take-out time, and take-out amount. As a result, for example, L92 is newly registered in addition to L91 previously registered as shown in the lower part of FIG. In this way, the history of the use of medicine is registered in the medicine management DB 2.
As described above, medicines can be managed by registering which medicines are used when and how much are used in the medicine management DB 2.

Next, the data registered in the medicine management DB 2 not only detects when and how much of the medicine has been used, but also issues a “warn when the prescribed usage amount is exceeded”, “fixed”. It is possible to provide services such as issuing a warning if there is a drug that does not return to the medicine table even after a certain amount of time has passed, or "providing a warning if there is a drug that is about to run out of stock." It is.
As a method for issuing a warning, for example, the management server 3 can make a sound from a speaker related to the management server 3 or display a warning text on a display device related to the management server 3.

For example, the “use amount” column of the medicine management DB 1 is searched, and a warning is issued when the use amount exceeds a predetermined rule. This makes it possible to “warn when a specified usage amount is exceeded”.
For example, when the prescribed usage amount is determined to be “within 10 per time” in advance, as shown in the upper L101 of FIG. 10, when the usage amount is 9, no warning is issued. However, when the usage amount is 20, as shown in the upper L102 of FIG.
In this way, it is possible to manage the abnormal use of medicines by issuing a warning when the prescribed usage amount is exceeded.

In addition, for example, when the “return time” and “return amount” in the medicine management DB 1 are blank and the take-out time exceeds a predetermined time, a warning is issued. This makes it possible to “provide a warning when there is a medicine that does not return to the medicine table even after a certain period of time”.
For example, when the current time is 2005/10/15 10:00: 00 and the specified export time is predetermined as “24 hours”, as shown in the middle L103 of FIG.
If the return time is not blank, no warning will be issued. However, as shown in the middle stage L104 in FIG. 10, the “return time” and “return amount” are blank and the time from the take-out time to the current time is a predetermined take-out time “24 hours” "Is exceeded, a warning is issued.
In this way, it is possible to manage the time for taking out medicines by issuing a warning when there is a medicine that does not return to the medicine table even after a certain period of time.

Further, for example, the “return amount” column of the medicine management DB 1 is searched, and a warning is issued when the return amount is equal to or less than a predetermined value. As a result, if there is a drug that is about to run out of stock, a warning is issued. Is possible.
For example, when it is determined that “out of stock” when the current amount of medicine is 10 or less, as shown in the lower part L105 of FIG. However, as shown in the lower part L106 of FIG. 10, a warning is issued for a return amount of 10 or less.
In this way, by detecting the out of stock first and issuing a warning, it is possible for the person who has seen the warning to replenish the medicine before the stock runs out and not run out of stock.

  As described above, by using data registered in the medicine management DB 2, it is possible to issue a warning when a consumable item is used in excess of a specified amount. Also, if there is a consumable container that does not return to the shelf after a certain period of time, a warning can be issued. Further, when there is a consumable item that is likely to be out of stock, a warning can be issued.

In the description so far, it has been described that medicines are taken out and returned one by one. However, the present invention is not limited to this, and can be applied when taking out and returning multiple medicines in parallel. It is. Processing in this case will be described below.
For example, it is assumed that the medicine A and the medicine B are placed on the medicine table. Here, it is assumed that medicine A is taken out and then medicine B is taken out. Then, the take-out time and take-out amount for the medicine A are registered in the medicine management DB 1, and the return time, the return amount, and the use amount are newly registered as blanks. Also, the take-out time and take-out amount for medicine B are registered, and the return time, return amount, and use amount are newly registered as blanks.
Here, assuming that medicine A is returned and then medicine B is returned, the return information of medicine A is registered in the return time, return amount and usage amount fields, and then medicine B is returned. Information at the time of return is registered in the time, return amount, and usage amount columns. Thus, even when taking out medicines A and B at the same time, management can be performed without any problem.
Conversely, the same applies to the case where medicine A is taken out, medicine B is then taken out, medicine B is returned later, and medicine A is then returned.

The above-described processing is carried out so that the weighing scale 1 and the chemical table with an RF reader can be identified to the extent that it is possible to identify that taking-out or returning is not simultaneous even when taking medicine A and medicine B almost simultaneously or returning them almost simultaneously. This can be achieved by shortening the measurement interval of 2 and measuring.
By shortening the measurement time in this way, chemicals can be managed by the method of the present invention even in almost the same case. Further, not only in the case of two medicines A and B but also in the case of taking out and returning a plurality of medicines in parallel, it can be similarly applied.

  Although the weight has been measured in the above embodiment, the same management may be performed by measuring the volume. In this case, as a method for measuring the volume, a method for measuring the volume by three-dimensional image processing, or in the case of a liquid in a container, the liquid level is measured, or the volume is measured by reflected light applied with light. May be.

The medicine management DB 1 or medicine-tag association DB 2 is a hard disk device, a magneto-optical disk device, a non-volatile memory such as a flash memory, a storage medium that can be read only, or a RAM (Random Access Memory). A volatile memory or a combination of these is assumed. Or it is a database apparatus using these.
The tag increase / decrease detection function unit 31, the mass increase / decrease detection function unit 32, or the drug increase / decrease recording function unit 33 in FIG. 1 may be realized by dedicated hardware, or a memory and a CPU (central processing unit). The function may be realized by loading a program for realizing the function into a memory and executing the program.
In addition, an input device, a display device, and the like (none of which are shown) are connected to the management server 3 as peripheral devices. Here, the input device refers to an input device such as a keyboard and a mouse. The display device refers to a CRT (Cathode Ray Tube), a liquid crystal display device, or the like.

As described above, according to the present invention, the RFID attached to the chemical container is used to measure the total amount of the chemical table having the RFID reader function and the plurality of chemical containers mounted on the chemical table (here, the weigh scale). As an example, we measured with a single weigh scale and a single RFID reader, and detected the change in the weight of the container of the changed medicine and the change in the RFID in real time. Can be detected.
In the description, the management of chemicals has been explained. However, the present invention is not only applicable to chemical management, and any solid or liquid other than chemicals can be used as long as it can enter a container with an RFID attached. It can be managed.

  In the description, as shown in FIGS. 7 to 9, for example, the medicine name is registered in the medicine management DB 2, and the medicine management DB 2 performs a search as to whether there is a target medicine for the medicine name. (For example, step S906 in FIG. 6), tag ID information corresponding to the drug name is registered in the drug management DB 2 in addition to the drug name, and whether there is target tag ID information for the registered tag ID information. Such a search may be performed from the medicine management DB 2.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and includes design and the like within a scope not departing from the gist of the present invention.

  The present invention is suitable for use in a consumable management system that manages medicines and the like.
