The drug return control device 6 is composed of an information processing device such as a desktop personal computer, a laptop personal computer, a workstation, or a tablet terminal. The drug return control device 6 is further connected to a database 5 that stores a plurality of tables 7a, 7b, 7c ... As a storage unit for data related to the drug.

The database 5 includes a returned drug dispensing device inventory table 7a, a returned drug dispensing device dispensing table 7b, a returned drug dispensing device collection table 7c, a returned drug dispensing device shared setting table, a drug master, etc. (see FIG. 2). , Includes drug-related data tables. On the other hand, the local database 3 attached to the instruction terminal 4 includes a drug-related data table such as a returned drug inventory table 9 (see FIG. 3).

The returned drug dispensing device inventory table 7a is a table (database) showing the contents of the returned drug stored in the returned drug dispensing device 2, and a new record is generated when the returned drug dispensing device 2 is returned. FIG. 2A shows the layout of the returned drug dispensing device inventory table 7a.

The returned medicine payout device payout table 7b is a table (database) showing the returned medicines existing in the returned medicine payout device 2 to be paid out and the contents of the payout, and is new when the returned medicine payout device 2 is returned.

The "collection" operation in the present embodiment is an operation in which drugs corresponding to specific conditions are collectively discharged from the storage unit 15, and the specific conditions include "expired" and "specific". It includes various conditions such as "being a drug type". Therefore, the "recovery" operation is a distinctly different operation from the drug "discharging" operation performed based on the prescription data. The "expiration date" may be paraphrased as "expiration date", but both terms are synonymous.

The drug master is a master file containing characteristic data and attribute data of each drug with the drug code as a key item (key field). The drug master of this embodiment may be a master file for the drug adopted by each hospital.

The returned drug inventory table 9 of the local database 3 is a local file showing a storage position (address) in the storage unit 15 of the returned drug dispensing device 2, and a new record is generated when the returned drug dispensing device 2 is returned. FIG. 3 shows the layout of the returned drug inventory table 9.

The storage information storage unit is a storage area for storing the storage status of the drug in the storage unit 15, and may be included in the storage unit of the instruction terminal 4, or is stored in the drug return control device (drug storage control device) 6. It may be included in the part.

The returned drug dispensing device (accommodated drug dispensing device) 2 exchanges necessary data with the drug return control device 6 and the instruction terminal 4 to exchange unused returned drugs stored in the returned drug management system (drug sorting device). , Recognized by the recognition unit 14 (described later), and according to the recognition, the returned drug is sorted and stored in its own (described later) storage unit 15. That is, the returned drug dispensing device 2 is based on the recognition operation of the recognition unit 14, and has a "drug identification code" (consisting of a return date and time to the returned drug dispensing device 2 and a serial number) and a "unit of the returned drug dispensing device itself". Understand data related to the properties of drugs such as "number", "drug barcode" (attached to each drug), "expiration date", "diameter and total length of drug", "direction and attitude of drug", etc. Based on these data, the returned drug management system is notified to search for the storage position in the storage unit 15. The returned drug management system searches for a filling position in the storage unit 15 of the returned drug dispensing device 2, that is, a vacant position and a placement method using the stored information storage unit, based on the data from the returned drug dispensing device 2.

The vacant position and how to put the returned medicine in the storage unit 15 will be described. As will be described later, the storage unit 15 is provided with a plurality of shelves in the vertical direction, and storage trays are arranged on each shelf. The storage trays on each shelf are provided with a plurality of rows, and each row has a plurality of lateral (directional) positions. The storage trays are classified into those for S size (drug), those for M size (drug), and those for L size (drug). When the returned drug management system receives the size (data) of the returned drug from the returned drug dispensing device 2, it determines whether the returned drug is of S, M, or L size, and identifies the corresponding storage tray. do. The returned drug management system then uses the stored information storage to find out (ie, search) if there is an area (including a margin area between the drugs) in which the drug of that size can be placed. If so, the filling position information (that is, the “shelf, row, horizontal position” data (which will be described later)) will be determined. At this time, the position where the mask is set (described later) is excluded from the search.

The instruction terminal 4 uses the filling position information determined as a result of the search, that is, the “shelf, row, horizontal position” data (described later) as the “drug identification code” or the “unit number of the returned drug dispensing device itself”. Notify the returned drug dispensing device 2 together with the data. The returned drug dispensing device 2 sorts and stores the returned drug in the storage unit 15 based on the received filling position information.

After sorting and storing the returned drug in the storage unit 15, the returned drug management system masks the filling position in the storage information storage unit. As a result, the agents will not be placed (stored) in the same position thereafter. In this way, in the storage information storage unit, a mask is set at the position where the medicine is placed in the storage tray, and the mask is removed at the position where the medicine does not exist (due to payout or the like), and the position is the place where the medicine can be placed (filled). Exists as. As described above, when searching for a placeable area, the returned drug management system tries to find a place where the drug to be placed can be placed (stored) most efficiently. Therefore, no wasted storage space is generated in the storage unit 15.

Further, the drug return control device 6 extracts the drug code from the "drug bar code" received from the returned drug dispensing device 2, searches the drug master in the database 5 using this drug code as a key item, and searches for the drug type and name. , Classification (cold storage, anti-cancer drug, powerful drug, etc.), etc. Further, the data indicating the occurrence of storage of the returned drug withdrawal device 2 in the storage unit 15 is immediately notified from the returned drug withdrawal device 2 to the drug return control device 6 and the instruction terminal 4, and the drug return control device 6 receives ( (As will be described later), a record is created in the returned drug payout device inventory table 7a (see FIG. 2 (A)) and the returned drug payout device payout table 7b (see FIG. 2 (B)), and the instruction terminal 4 is used. Creates a record in the returned drug inventory table 9 (see FIG. 3) in the local database 3. At this time, in the returned drug inventory table 9 in the local database 3, the data related to the stored drug and the data related to the filling position in the storage unit 15 are stored in association with each other.

At the time of drug withdrawal, the drug return control device 6 generates a payout instruction specifying the conditions of the drug to be paid out and sends it to the returned drug payout device 2. The returned drug payout device 2 performs a payout operation according to a payout instruction received from the drug return control device 6.

Even when the entire payout line system 101 (see FIG. 4) including the returned drug payout device 2 (described later) is stopped at night, for example, the return operation of the returned drug payout device 2 and the corresponding instruction terminal. Only the operation of 4 may be in operation. In that case, only the contents of the returned drug inventory table 9 of the local database 3 will be updated. Therefore, when the entire payout line system 101 is restarted the next morning, the tables stored in the database 5 (returned medicine payout device inventory table 7a, returned medicine payout device payout table 7b, returned medicine payout device collection table) are stored. 7c etc.) and the local database 3 (returned drug inventory table 9 etc.) attached to the instruction terminal 4 are synchronized with each other.

The returned medicine withdrawal device 2 and the instruction terminal 4, and the returned medicine withdrawal device 2 and the medicine return control device 6 are connected via RS-232C or the like, respectively. Further, the instruction terminal 4 and the drug return control device 6 are connected via a LAN or the like.

1.2. Configuration of the payout line system The figure shown in the upper part of FIG. 4 is an overall configuration diagram of the payout line system 101 including the returned drug payout device 2 of the present embodiment. A tray for paying out and collecting the returned medicine passes through the payout line system 101. The payout line system 101 may have various device configurations depending on the user's specifications. For example, in FIG. 4, the supply lifter 103, the bottle payout machine 105, the returned medicine payout device 2, the random payout machine 107, and the special payout machine 109. It is composed of a cold place dispenser 111, a bagging machine 113, a printer unit 115, a discharge lifter (with rewrite) 117, a stacking lifter 119, and the like.

The supply lifter 103 is a device for filling a tray that flows from left to right in the payout line system 101. The bottle dispenser 105 is a device that dispenses an infusion bag (physiological saline solution). The random dispenser 107 is a device that dispenses ampoules. The special dispenser 109 is a device that dispenses an ampoule having a special shape (such as a 5-unit ampoule). The cold place dispenser 111 is an ampoule-dedicated payout device that needs to be stored in a cold place. The bagging machine 113 is a device for filling a bag (medicine bag) with the chemicals discharged up to the bagging machine 113. The printer unit 115 is a device that prints a label with an injection slip (a list of medicines dispensed in a tray based on a prescription) and information on a patient to be administered (attached to a medicine bag or the medicine itself). The random dispenser 107 and the special dispenser 109 dispense new ampoules (ie, non-returned agents). The random payout machine 107 and the special payout machine 109 in the payout line system 101 can be configured as any payout machine.

The payout line system 101 may be configured differently from that shown in FIG. 4, and may include, for example, two or more returned drug payout devices 2. The payout line system 101 may also include a cassette type injectable drug dispenser. The cassette-type injection dispenser usually has a method of arranging and storing a specific drug in a cassette dedicated to the drug, and a method of randomly storing a specific drug in the cassette dedicated to the drug. The above-mentioned random dispenser 107 is of a method of randomly accommodating a specific drug in a cassette dedicated to the drug.

The cassette-type injection dispensing machine is a device that dispenses an ampoule packed in a cassette from the cassette. The cassette for storing the medicine is inserted and held in the cassette type injection medicine dispenser. A large number of cassettes are arranged in the vertical (vertical) direction and the horizontal direction of the cassette type injection dispenser. Inside the cassette, the medicine corresponding to each cassette is stored. When the cassette-type injection drug dispenser receives a signal to dispense a specific drug from the drug return control device 6 or the instruction terminal 4, the cassette-type injection drug dispenser dispenses the specific drug from the cassette storing the specific drug.

In addition, a virtual cassette (concept) that virtually corresponds to the above-mentioned cassette type injection drug dispenser may be constructed. The storage unit 15 of the returned medicine dispensing device 2, which will be described later, is not constructed by an actual cassette, but can virtually or logically store the medicine according to the concept of the cassette.

The above-mentioned drug master can include data of an inventory upper limit, an inventory constant, and an inventory lower limit for each drug (drug code). In the storage unit 15 of the returned drug dispensing device 2, individual drugs (drugs) are stored in various storage positions (storage addresses), but when grouped by drug, the same drug is virtually the whole provided by the storage unit 15. A certain area will be provided in the storage area. The idea of the virtual cassette is to manage the area for each of the same chemicals with restrictions imposed by the inventory upper limit (in terms of quantity), the inventory constant, and the inventory lower limit.

Here, the "inventory constant" is the number corresponding to the virtual allocation area where only the chemical can be placed. This "inventory constant" is a basic numerical value in the concept of a virtual cassette. The "inventory constant" is sometimes referred to as the "maximum mounting amount". Next, the "inventory upper limit" is an upper limit value of the number of chemicals that may be virtually occupied in the storage unit 15. However, there is a possibility that other chemicals may enter the area that can be virtually occupied by the upper limit. Further, the "stock lower limit" is a boundary value for notifying the outside that the remaining amount of chemicals is small. The "lower limit of inventory" is sometimes referred to as the "filling standard amount".

In the record for each drug (drug code) in the drug master, all of the inventory upper limit, the inventory constant, and the inventory lower limit may or may not be set. As described above, the medicines stored in the storage unit 15 of the returned medicine dispensing device 2 and the medicines stored in the cassette of the cassette type injection medicine dispensing machine according to the concept of the virtual cassette are hereinafter referred to as "cassette medicines". Sometimes.

1.3. Configuration of Returned Drug Dispensing Device The figure shown at the bottom of FIG. 4 is a schematic block diagram of the returned drug dispensing device 2 in the returned drug management system according to the first embodiment. The returned drug payout device 2 performs a return operation for storing unused (ampoules, vials, etc.) returned drugs, a payout operation for discharging the stored returned drugs, and a collection operation for collecting the stored returned drugs. be able to. The returned medicine dispensing device 2 includes a receiving unit 12, a recognition unit 14, a storage unit 15, and a dispensing unit 16.

The receiving unit 12 is configured to accept, for example, seven return trays (see FIG. 20). The return tray is, for example, a tray that first stores returned drugs such as ampoules and vials that have not been used in the individual wards of the hospital. The recognition unit 14 recognizes the medicine contained in the medicine sorting device. That is, the recognition unit 14 recognizes data such as the orientation, posture, shape, diameter and total length of the returned drug placed on each return tray, as well as the drug code and the expiration date by image processing. The returned drug recognized by the recognition unit 14 is stored in the storage unit 15.

The returned drug such as an ampoule or a vial is adsorbed by the first suction nozzle and the first suction pad included in the first robot included in the returned drug dispensing device 2, and is adsorbed by the first robot from the return tray to the recognition unit 14. Will be transferred to. Further, the returned medicines are sucked by the second suction nozzle and the second suction pad included in the second robot included in the returned medicine dispensing device 2, and are sucked by the second robot from the recognition unit 14 to the storage unit 15. Will be transferred to. The first suction nozzle and the second suction nozzle are capable of releasably sucking the returned chemicals by the vacuum supplied from the vacuum source, and the first suction pad and the second suction pad made of rubber are respectively attached to the tips thereof. It is attached.

The dispensing unit 16 dispenses the drug stored in the storage unit 15 to a tray passing through the inside of the dispensing line system 101 according to a prescription instruction from the drug return control device 6. Further, the payout unit 16 passes the medicine stored in the storage unit 15 inside the payout line system 101 according to a collection instruction (dummy prescription instruction) input from the instruction terminal 4 and generated by the medicine return control device 6. Collect to.

2. 2. Operation 2.1. Return operation of the returned drug payout device The returned drug payout device 2 receives the return tray on which the returned drug is placed at the receiving unit 12, recognizes the returned drug by the recognition unit 14, and stores the returned drug according to the recognition. By sorting and storing the returned medicines, the returned medicines are returned. The returned drug management system is configured so that the user of the returned drug management system can give an instruction to start the return operation on either the returned drug payout device 2 or the instruction terminal 4.

The receiving unit 12 of the returned medicine dispensing device 2 receives, for example, seven return trays on which the returned medicine such as an ampoule or a vial is placed. As shown in FIG. 20, each of these seven return trays is stacked and temporarily stored in the receiving unit 12.

Of the seven return trays that are stacked and temporarily stored, the lowest return tray can be made to function as an NG (No Good) tray. That is, the returned drug payout device 2 can also perform an operation of setting "NG" as a returned drug that is determined not to be necessary to be put in the storage unit 15 in the first place and transferring the returned drug to this NG tray. Examples of the target to be transferred to the NG tray include the following three types.
[1] The shape of the medicine is not the shape of a general ampoule or vial [2] The shape of the medicine is set as "non-returnable medicine" on the "Return permission setting" screen described later [3] Database connected to the medicine return control device 6 Drugs that are not registered in the drug master included in the above, and whether or not each returned drug falls under these [1] to [3] is determined by the control unit of the recognition unit 14 and the instruction terminal 4. In particular, when determining whether or not it corresponds to [2] or [3], the database connected to the drug return control device 6 is referred to ([2] will be described later). A return tray other than the lowermost return tray may function as an NG tray. At this time, the lowermost return tray may function as a non-NG tray.

The returned medicines placed on the individual return trays (excluding the NG tray) are recognized by the recognition unit 14 by image processing. At that time, data such as a barcode including a drug code and an expiration date are acquired.

A "drug identification code" is assigned to each drug returned. This "drug identification code" is, for example, a unique identification code composed of "date and time of return of the return tray to the returned drug dispensing device" + "serial number".

The returned drug payout device 2 transmits the recognized data to the drug return control device 6 and the instruction terminal 4. Based on the transmitted data, the drug return control device 6 records in the returned drug payout device inventory table 7a (see FIG. 2A) and the returned drug payout device payout table 7b (see FIG. 2B). Is created, and the instruction terminal 4 creates a record in the returned drug inventory table 9 (see FIG. 3) in the local database 3.

The returned drug recognized by the recognition unit 14 is sorted and stored in the storage unit 15. The storage unit 15 is provided with a plurality of shelves in the vertical direction, and each shelf is provided with a plurality of rows. In addition, each row has multiple lateral (directional) positions. That is, in the storage unit 15, the storage position (storage address) of the drug is uniquely determined by (shelf, row, horizontal position). This (shelf, column, horizontal position) information is the returned drug inventory table 9 shown in FIG. 3, which is the local database 3 as the fields of "filling shelf number", "filling column number", and "filling horizontal position". Recorded in the record.

2.2. Dispensing operation of the returned drug dispensing device As described above, the dispensing unit 16 of the returned drug dispensing device 2 dispenses the drug stored in the storage unit 15 inside the dispensing line system 101 according to the prescription instruction from the drug return control device 6. Pay out to the passing tray.

The drug return control device 6 receives prescription data from an external system (for example, a hospital integrated system), refers to the returned drug payout device payout table 7b (see FIG. 2B), and records the target drug code. If there is, "allocation processing" is performed so that the drug is preferentially dispensed. After the allocation process, the drug return control device 6 sends the withdrawal instruction data including the drug code and the number of withdrawals to the returned drug withdrawal device 2. For other drugs that do not exist in the returned drug payout device 2, the drug return control device 6 is such that the random payout machine 107 or the cold place payout machine 111 on the payout line system 101 pays out the medicine or the cold. The payout instruction data is sent to the payout machine 111.

Based on the sent withdrawal instruction data (drug code, number of medicines), the returned medicine dispensing device 2 and the returned medicine management system are the medicines in each record of the returned medicine inventory table 9 (see FIG. 3) of the local database 3. Search the code to redetermine (re-extract) the drug to be extracted. At this time, the item of "expiration date" of each record of the returned drug inventory table 9 is referred to. This is because, as will be described later, returned medicines with an unknown expiration date and returned medicines with a near expiration date may be preferentially paid out. Since there is a possibility that other prescription instructions may be canceled after the allocation process of the drug return control device 6, the returned drug payout device 2 redetermines (re-extracts). In the specific extraction (delivery) work, the data in the fields of "filling shelf number, filling row number, filling horizontal position" is used.

When the number of medicines in stock in the storage unit 15 is larger than the number of medicines to be paid out, the medicine return control device 6 and the returned medicine withdrawal device 2 determine the priority of withdrawal as follows. First, if the "expiration date" of the returned drug dispensing device inventory table 7a or the returned drug inventory table 9 is unknown (that is, the data regarding the "expiration date" is blank), that is given priority. Next, those having a close "expiration date" in the returned drug payout device inventory table 7a and the returned drug inventory table 9 have priority over those having a distant "expiration date". When the returned drug payout device 2 is incorporated in the payout line system 101 by a plurality of units, it is also assumed that there are returned drugs having the same expiration date among the plurality of returned drug payout devices 2. In this case, the priority may be determined among the plurality of returned drug dispensing devices 2 (that is, between the units). As will be described later, drugs for which the "expiration date" is unknown may not be subject to withdrawal. In that case, as described above, the priority of payout may be determined according to the priority according to the content of the "expiration date" and the priority between units.

FIG. 5 (1) is a diagram showing a processing flow at the time of payout. The tightening monitor 86 in FIG. 5 (1) is a function of the drug return control device 6. The tightening monitor 86 monitors the prescription data 85 updated by the external system. The closing monitor 86 performs an allocation process on the record of the return drug payout device payout table 7b based on the updated prescription data 85. As a result, the drug return control device 6 generates the payout instruction data 87, and in response to the generated payout instruction data 87, the returned drug payout device 2, the random payout machine 107, the cold place payout machine 111, and the like perform ampoule picking processing ( The payout) 91 is carried out, and the payout line system 101 creates a summary table 89.

FIG. 6 is a specific flowchart of the withdrawal process of the returned medicine withdrawal device 2 and the returned medicine management system shown in FIG. 5 (1). First, the drug return control device 6 periodically processes the prescription data 85 from the external system together (tightening process) (ST41). The drug return control device 6 checks whether or not there is a record of the target drug in the returned drug payout device payout table 7b (ST42), and if so, performs an allocation process on the record of the drug (ST43). If not, the drug return control device 6 transmits the prescription data 85 to a payout machine other than the returned medicine payout device 2 (for example, a random payout machine 107 or a cold place payout machine 111). The tightening process (ST41) may be configured to be performed immediately after the allocation process (ST43).

When the drug return control device 6 confirms that the record of the target drug exists in the returned drug payout device payout table 7b (ST42 / YES) and performs the allocation process for the drug record (ST43), the product is returned. The payout instruction data 87 is sent to the drug payout device 2 (ST44). On the other hand, the returned drug dispensing device 2 redetermines (re-extracts) the record of the corresponding drug code from the returned drug inventory table 9 of the local database 3. At this time, as described above, the item of "expiration date" of each record of the returned drug inventory table 9 is referred to (ST45). The returned drug payout device 2 pays out the drug by recognizing the "filling shelf, filling row, filling horizontal position" of the drug from the determined (extracted) data (ST46).

Upon receiving the withdrawal of the returned drug withdrawal device 2, the drug return control device 6 updates the "payout completion date and time (payout completion date, withdrawal completion time)" of the record in the returned drug withdrawal device withdrawal table (ST47). The returned drug management system updates the "payout completion date (payout completion date, payout completion time)" of the relevant record in the returned drug inventory table 9 (ST48). At the same time, the returned drug management system sets the field of "reason for withdrawal" of the record in the returned drug inventory table 9 to the data indicating "withdrawal". In response to the withdrawal of the returned drug withdrawal device 2, the returned drug management system removes the mask from the stored information storage unit at the position where the drug no longer exists due to the withdrawal. Therefore, in the stored information storage unit, the position becomes an arrangement (filling) possible area.

2.3. Operation of Returned Drug Management System This section describes the operation of the Returned Drug Management System. FIG. 7A is a main screen view of the returned drug management system in the returned drug management system according to the first embodiment. The operation screen of the returned drug management system including the main screen is displayed and operated by the instruction terminal 4. The user can select various processes (functions) on this main screen. The returned drug management system performs processing according to the user's choice. The following are examples of the main processes (functions) that the returned drug management system can perform.
[1] Drug recovery process [2] Expiration date registration process [3] Return permission setting process [4] Ward registration process [5] Various display processes The operation of the returned drug management system will be described below for each process.

2.3.1. Chemical recovery processing 2.3.1.1. Using the chemical recovery screen The chemical recovery process is performed in the order of (a) setting the chemical recovery processing conditions, (b) extracting the chemicals to be recovered, and (c) executing the recovery.

When the drug recovery button 30 is touched (or clicked) on the main screen shown in FIG. 7 (a), the screen shifts to the drug recovery screen shown in FIG. The chemical recovery screen includes a recovery extraction condition setting unit 56 on the left side thereof. In the extraction condition setting unit 56, when the detailed condition is input by the user, the check box for the detailed condition is checked ((a) setting of the drug recovery processing condition), and the extraction execution button is clicked, the instruction terminal 4 Displays (data) of chemicals that meet the extraction conditions in the upper right corner of the screen.

The extraction of data and the display of the extracted data are performed by each record of the returned drug dispensing device inventory table 7a (or the returned drug inventory table 9 of the local database 3) and the drug contained in the database 5 connected to the drug return control device 6. It is based on the master. The process for extracting the target data of the drug recovery process will be specifically described with reference to FIG. 9.

The control unit of the instruction terminal 4 reads out each record of the returned drug dispensing device inventory table 7a (ST02, ST03). Next, the control unit of the instruction terminal 4 determines whether the extraction condition is related to the data stored in the drug master, or is set in the returned drug dispensing device inventory table 7a (or returned drug inventory table 9) (each record). It is determined whether it is related to the stored data (ST04).

When the extraction condition set on the drug collection screen is related to the data stored in the drug master, the control unit of the instruction terminal 4 uses the drug code included in each record of the returned drug dispensing device inventory table 7a as a key item. Search for the drug master as (ST05). If the content of the field data (for example, the drug type flag) in each record of the searched drug master matches the extraction conditions, the control unit of the instruction terminal 4 extracts and displays the returned drug from the returned drug dispensing device inventory table 7a. (ST06, ST07, ST08, ST09).

For example, the record of the drug master in which "psychotropic drug" is selected as the extraction condition on the drug recovery screen of FIG. 8 and the drug code included in a certain record of the returned drug dispensing device inventory table 7a is searched as a key item. If "1" is set in the "drug type flag" of the above, the control unit of the instruction terminal 4 considers that the content of the field data in the record of the searched drug master matches the extraction condition, and determines that the returned drug dispenser device. The record of the inventory table 7a is extracted and displayed.

On the other hand, when the extraction condition set on the drug collection screen is related to the data stored in the returned drug dispensing device inventory table 7a (or the returned drug inventory table 9) (each record) (for example, the extraction condition is ". Fields (for example, "expiration date", "creation date", etc.) of the returned drug dispensing device inventory table 7a (or returned drug inventory table 9), such as "long-term retention", "expiration date", "expiration date approaching", etc.) Extraction / display is performed based on the field) (ST10, ST11, ST12, ST13) ((b) Extraction of the drug to be collected). The above processing is performed for all the records in the returned drug payout device inventory table (ST03, ST14).

FIG. 10 is a flowchart mainly showing the specific processing in step ST10 of FIG. 9 when the extraction condition is “close to the expiration date”. That is, in the flowchart shown in FIG. 10, does each record in the returned drug inventory table 9 of the local database 3 meet the collection / extraction condition of "close to expiration date" based on the data of the "expiration date" item in the record? Is being processed to check. In this flowchart, both the data files are treated as being synchronized between the returned medicine dispensing device inventory table 7a and the returned medicine inventory table 9 of the local database 3.

First, the "expiration date coming soon" data is set and stored (ST22). The setting of the "expiration date approaching days" data may be set by, for example, one of the functions related to the various setting buttons on the main screen of FIG. 7 (a). The set data may be stored in, for example, a returned drug dispensing device shared setting table connected to the drug return control device 6. Next, the user selects the "close to expiration date" check box of the extraction condition setting unit 56 for collection on the drug collection screen shown in FIG.

When the "Expiration date is approaching" check box is selected, the control unit of the instruction terminal 4 reads out each record of the returned drug inventory table 9 in order (ST24). Using the "expiration date" data in the record of the returned drug inventory table 9 and the "expiration date approaching days" data stored in the returned drug dispensing device shared setting table, the control unit of the instruction terminal 4 has an expiration date. Calculation (determination) of whether or not it is imminent is performed (ST26). If it is calculated (determined) that the expiration date is approaching, the control unit of the instruction terminal 4 extracts and displays (ST27, ST28). The above processing is performed for all the records in the returned drug inventory table 9 of the local database 3 (ST25, ST29).

If the "cassette chemicals" described above are excluded from the target of chemical collection, the "cassette chemical exclusion" check box will be checked. Further, when the "upper limit chemicals" button 55 is touched (or clicked), only the chemicals exceeding the "stock upper limit" in the (virtual) cassette are targeted for drug collection. If the "Not eligible for withdrawal" check box is checked, non-implemented drugs other than the mounted drug (that is, "cassette drug") that are not paid out by the returned drug withdrawal device 2 are targeted for drug collection. Will be done. This makes it possible to clearly sort the medicines to be dispensed from the payout line system 101 and the medicines to be dispensed manually.

Next, (c) collection execution will be described. When the "collection execution" button 57 on the drug collection screen shown in FIG. 8 is touched (or clicked), the control unit of the instruction terminal 4 gives a collection instruction to the returned drug dispensing device 2. At this time, the control unit of the instruction terminal 4 refers to the returned medicine payout device inventory table 7a and refers to the returned medicine payout device collection table 7c included in the database 5 connected to the medicine return control device 6 (FIG. 2 (C). )) Write new data (record).

FIG. 5 (2) is a diagram showing a flow of processing at the time of collection. The recovery audit monitor 88 in FIG. 5 (2) is a function of the drug return control device 6, and whether the instruction terminal 4 newly writes data to the returned drug dispensing device recovery table 7c (see FIG. 2 (C)). Always monitor whether or not. Specifically, the collection audit monitor 88 monitors whether or not the "collection serial number" field in the return drug dispensing device collection table 7c is incremented. The recovery audit monitor 88 of the drug return control device 6 generates dummy prescription instruction data (recovery data) 90 due to the occurrence of new writing of data to the returned drug dispensing device recovery table 7c. The generated dummy prescription instruction data (recovery data) 90 is transmitted from the drug return control device 6 to the returned drug dispensing device 2 in order to carry out the ampoule picking process (recovery operation) 92.

Since the instruction data here is collected data and not actual prescription data, it is referred to as "dummy prescription instruction data". Here, the "dummy prescription" is different from the prescription for each patient sent from an external system (for example, the hospital integrated system), and the "dummy prescription" is used to pay out the drug based on the above-mentioned various extraction conditions. It is instructional information, and causes the returned medicine payout device 2 to perform the same operation as the payout based on a normal prescription.

In response to the "dummy prescription instruction data", the returned drug dispensing device 2 refers to and searches the returned drug inventory table 9 in the local database 3 based on the drug identification code included in the dummy prescription instruction data, and identifies the drug. Grasp the "filling shelf number, filling row number, filling horizontal number" of the drug with the code, and perform the actual collection work based on the grasped "filling shelf number, filling row number, filling horizontal number" ( (C) Collection execution).

FIG. 11 is a specific flowchart of the collection process shown in FIG. 5 (2). First, the instruction terminal 4 extracts the collection target drug data based on the extraction conditions set on the drug recovery screen, and gives a recovery instruction to the extracted drug (ST61). Immediately after the collection instruction, the instruction terminal 4 writes a new record in the returned drug dispensing device collection table 7c with reference to the returned drug dispensing device inventory table 7a. The recovery audit monitor 88 in the drug return control device 6 checks that a new record has been created in the return drug delivery device recovery table 7c (ST63), and issues dummy prescription instruction data (recovery data) 90 (recovery data). ST64). Upon receiving the dummy prescription instruction data (collection data) 90, the returned drug dispensing device 2 extracts a record of the drug identification code in the dummy prescription instruction data (collection data) 90 from the returned drug inventory table 9 (ST65). The returned medicine dispensing device 2 recognizes the "filling shelf, filling row, filling horizontal position" of the drug from the extracted data, and performs the collection operation based on the recognized "filling shelf, filling row, filling horizontal position". (ST66).

In response to the collection work of the returned drug payout device 2, the drug return control device 6 sets the "payout completion date and time (payout completion date) of the record including the drug identification code in the dummy prescription instruction data in the returned drug payout device inventory table 7a. , Payout completion time) ”is updated. At the same time, the drug return control device 6 updates the "payout completion date (payout completion date, payout completion time)" of the record including the drug identification code in the dummy prescription instruction data in the returned drug payout device collection table 7c (the payout completion date and time). ST67). The returned drug management system updates the "payout completion date (payout completion date, payout completion time)" of the record in the returned drug inventory table 9 (ST68). At the same time, the returned drug management system sets the field of "reason for withdrawal" of the record in the returned drug inventory table 9 to the data indicating "instruction collection". As in the case of withdrawal, upon collection of the returned drug withdrawal device 2, the returned drug management system removes the mask at the position where the drug no longer exists due to the collection in the stored information storage unit. Therefore, in the stored information storage unit, the position becomes an arrangement (filling) possible area.

2.3.1.2. By the automatic collection setting screen In the instruction terminal 4, the above-mentioned "(a) setting of chemical collection processing conditions" can be performed on another screen. When the various setting buttons 34 are touched (or clicked) on the main screen shown in FIG. 7 (a), a group of setting screen buttons (34a) for branching to various setting screens as shown in FIG. 7 (b). ~ 34e) is displayed. Here, when the "automatic collection setting" button 34a is touched (or clicked), the automatic collection setting (pattern setting) screen shown in FIG. 12 is displayed. This screen is a screen for giving an instruction in advance to the returned drug payout device 2 so that the collection work is performed when a predetermined date and time (time) or a predetermined condition is satisfied. The screen shown in FIG. 12 is configured to set a "predetermined date and time (time)" at the bottom of the screen. Further, the "satisfaction of a predetermined condition" is, for example, "when the stock shelf is full" or "the timing when all the returned medicines in the return tray are returned" as shown in FIG. This "when the stock shelves are full" and "when all the returned medicines in the return tray are returned" are the buttons 58a when the shelves are full and the return on the automatic collection setting (pattern setting) screen shown in FIG. It is set by turning on the button 58 at the time of completion.

In the automatic collection setting (pattern setting) screen shown in FIG. 12, detailed conditions are input via the automatic collection condition setting unit 56a at the top of the screen, or a check box related to the detailed conditions is checked. Then, the chemical recovery processing conditions are set.

When the "Expiration date is approaching" check box of the automatic collection condition setting unit 56a of the automatic collection setting (pattern setting) screen shown in FIG. 12 is checked and then the main screen of FIG. 7A is returned, the instruction terminal 4 If it is determined that the target record is in the returned drug dispensing device inventory table 7a, the display of the button 22 on the main screen of FIG. 7 (a) is changed from "no drug near expiration date" to "with drug near expiration date". And make the button 22 blink. Here, when the "drugs near expiration date" button 22 is touched or clicked, the drug recovery screen shown in FIG. 8 is displayed, in which the drugs (data) conforming to the extraction conditions are displayed. After that, when the "collection execution" button 57 is clicked, the collection instruction is executed.

Even if the collection instruction is not given by the "collection execution" button 57, the returned drug withdrawal device 2 is based on the conditions and date and time for automatic collection set on the automatic collection setting (pattern setting) screen of FIG. The collection instruction to is executed.

Even when a check box such as "long-term retention" in the automatic collection condition setting unit 56a of the automatic collection setting (pattern setting) screen shown in FIG. 12 is checked, the same processing as described above is executed. The "upper limit excess drug" button 56a, the "cassette drug exclusion" check box, and the "not payable" check box have the same functions as the buttons and check boxes on the drug recovery screen of FIG.

As described above, on the automatic collection setting (pattern setting) screen shown in FIG. 12, a predetermined date and time (time) and a predetermined condition, which are the reference for performing the collection work, are set. That is, the collection work is performed when these predetermined dates and times (time) and predetermined conditions are satisfied. Here, even if the returned drug management system is configured, the drug recovery process of the present embodiment is performed when the filling rate of the drug in the storage unit 15 of the returned drug dispensing device 2 becomes equal to or higher than a predetermined threshold value. good. The "filling rate" here is the ratio of the number of drugs actually stored in the storage unit 15 to the maximum number of drugs that can be stored in the storage unit 15.

The automatic collection condition setting unit 56a of the automatic collection setting (pattern setting) screen shown in FIG. 12 is also provided with a check box for “return designation”. The data indicated by this "return designation" check box indicates that the drug is subject to return drug management (drug sorting). When this "Return designation" check box is checked, the chemicals designated for return will be subject to automatic collection in the data. Whether or not the return is specified in the data is the target of the return specification if the content of the "designated drug flag" field of the returned drug dispensing device inventory table 9 (that is, the "designated drug flag" is set. ). Regarding the classification of whether or not each chemical is subject to "return designation", for example, a setting screen for each chemical may be separately provided in the instruction terminal 4.

Further, the automatic collection condition setting unit 56a on the automatic collection setting (pattern setting) screen shown in FIG. 12 is also provided with a check box for “non-loaded drug”. The data indicated by this "non-loaded drug" check box indicates that the drug is not subject to returned drug management (drug sorting) (that is, it is not loaded in the returned drug management system (drug sorting device)). Non-carrying drugs include, for example, infrequently used drugs such as those used only in special injury and illness surgery, and drugs that should be handled with care. When this "non-carrying drug" check box is checked, the drug set as non-carrying drug in the data is subject to automatic collection. Whether or not it is set as a non-loaded drug in the data is determined by the contents of the "non-loaded drug flag" field of the returned drug dispensing device inventory table 9 (that is, if the "non-loaded drug flag" is set. , It is a non-loaded drug). Regarding the classification of whether or not each drug is a “non-loaded drug”, for example, a setting screen for each drug may be separately provided on the instruction terminal 4.

The above-mentioned check box for "return designation" and the check box for "non-loaded drug" may be provided in the extraction condition setting unit 56 on the left side of the drug recovery screen shown in FIG.

In the returned drug management system, a plurality of conditions / dates (that is, automatic collection patterns) for automatic collection may be provided. As described above, when the various setting buttons 34 are touched (or clicked) on the main screen shown in FIG. 7 (a), the setting for branching to the various setting screens as shown in FIG. 7 (b). A group of screen buttons (34a to 34e) are displayed. When the "automatic collection setting" button 34a is touched (or clicked), the automatic collection setting (pattern setting) screen shown in FIG. 12 is displayed. Here, first, as shown in FIG. 13, The "automatic collection setting" screen showing a list of conditions / dates for a plurality of automatic collections may be displayed.

In the automatic collection setting screen shown in FIG. 13, when the "add pattern" button 150 is touched (or clicked), the automatic collection setting (pattern setting) screen shown in FIG. 12 is displayed subsequently and for the first time. When the chemical recovery processing conditions are set on the automatic recovery setting (pattern setting) screen shown in FIG. 12 and the "Register" button is touched (or clicked), the chemical recovery processing conditions are registered and then FIG. 13 Return to the automatic collection setting screen shown in. When this returns, the registered drug recovery processing conditions are included in the list and displayed. As described above, when the touch of the "pattern addition" button 150 in FIG. 13 and the setting / registration of the drug recovery processing conditions in FIG. 12 are performed a plurality of times, a plurality of drugs are displayed on the automatic recovery setting screen shown in FIG. The collection processing conditions, that is, the conditions and date and time for automatic collection (automatic collection pattern) are displayed after being set and registered in the returned drug management system. The "pattern change" button shown in FIG. 13 is a button for advancing to the screen for changing the automatic collection pattern, and the "pattern deletion" button is a button for deleting the automatic collection pattern. The column of selection check 156 is a check column for selecting chemical recovery processing conditions. When the plurality of selection check 156 columns are selected, the selected chemical recovery processing conditions are combined (for example, by AND conditions) to determine the actual chemical recovery processing conditions. The data related to the plurality of drug recovery processing conditions may be stored in the local database 3, for example, the returned drug dispensing device shared setting table. Specifically, whether to perform the drug recovery process when the return process is completed (that is, whether to perform the drug recovery process when "predetermined conditions are satisfied") or to perform the drug recovery process when the timer is set (that is, "predetermined date and time (that is, whether to perform the drug recovery process"). Data such as whether to perform chemical recovery processing at "time") "is stored.

As described above, by the drug collection process by the returned drug management system, unnecessary returned drugs and inappropriate returned drugs that are not suitable for storage are appropriately and timely removed from the returned drug dispensing device 2. This prevents unnecessary inventory and wasteful inventory from being generated in the storage unit 15. Therefore, the efficiency and certainty (safety) in the payout work of the returned medicine payout device 2 are enhanced.

2.3.1.3. About the modified example of the chemical recovery process The modified example of the chemical recovery process will be described. The receiving unit 12 of the returned medicine dispensing device 2 shown in FIG. 20 is configured to accept up to seven return trays. The receiving unit 12 of the returned medicine dispensing device 2 may be configured to accept eight or more return trays.

Here, the return completion button 58 on the automatic collection setting (pattern setting) screen shown in FIG. 12 is "on", and the "timing when all the returned medicines in the return tray are returned" automatically collects. It is assumed that it is set as a timing.

In this case, the returned drug management system automatically performs the returned drug dispensing device 2 immediately after the return of 7 return trays (6 return trays when the NG tray is set) is completed. Instead of instructing to perform the collection work, a pop-up of "Do you want to perform automatic collection?" And a "Yes" and "No" buttons may be displayed on the screen of the instruction terminal 4. When the "Yes" button is selected, the returned drug management system instructs the returned drug dispensing device 2 to perform an automatic collection operation. When the "No" button is selected, the return drug management is completed by completing the return of the 8th and subsequent return trays (7 or more return trays if the NG tray is set). A returned drug management system may be configured such that the system instructs the returned drug dispensing device 2 to perform an automatic collection operation.

2.3.2. Expiration date registration process 2.3.2.1. Processing to register an unknown expiration date If the returned drug management system determines that there is a record whose "expiration date" is unknown (that is, not entered) in the returned drug dispensing device inventory table 7a, FIG. 7 The display of the button 28 on the main screen of (a) is changed from "no chemicals with unknown expiration date" to "with chemicals with unknown expiration date", and the button 28 is blinked. Here, if the "drug with unknown expiration date" button 28 is touched (or clicked), a list of drugs (data) whose "expiration date" field is unknown is displayed, and the drug validity shown in FIG. 14 is displayed. The deadline registration list screen is displayed. As mentioned above, "expiration date" may be paraphrased as "expiration date", but both terms are synonymous.

Also on the drug expiration date registration list screen shown in FIG. 14, the display of the list can be narrowed down by setting the extraction condition setting unit 62.

When one line is touched (or clicked) in the list of the drug expiration date registration list screen shown in FIG. 14, the drug expiration date registration screen shown in FIG. 15 is displayed. On this screen, the image data of the drug related to the touched line, which is acquired by the recognition unit 14 of the returned drug dispensing device 2, is displayed. On the drug expiration date registration screen, the expiration date is input (registered) by the user based on the image data of the drug. This registration screen includes a field for inputting a registrant's ID (identifier), and the registrant's ID may be simultaneously input (registered) through the field. The image data of the drug is stored in the local database 3 for each drug to which the individual drug identification code is assigned (that is, for each drug identification code).

By the expiration date registration process by the returned drug management system, it is possible to additionally register the expiration date even for the drug whose expiration date is not recognized. As a result, the number of drugs subject to expiration date management in the returned drug dispensing device 2 can be further increased, and inadvertent inventory is not generated, and the expiration date is expired without using the drugs that could be used. There is no need to waste money.

2.3.2.2. Process for re-reading the expiration date The "re-read" button 63 on the drug expiration date registration list screen shown in FIG. 14 displays the returned drug stored in the storage unit 15 of the returned drug dispensing device 2 as an image of the recognition unit 14. It is a button for re-acquiring the data including the expiration date by making it recognized again by the process. Specifically, the "reread" button 63 is touched (or clicked) while touching (or clicking) one line of the list on the drug expiration date registration list screen. By doing so, the returned drug dispensing device 2 returns the drug shown in the touched line from the storage unit 15 to the recognition unit 14, and causes the recognition unit 14 to perform recognition by image processing again. After reacquiring the data including the expiration date, the returned drug payout device 2 stores the reread drug in the storage unit 15 again. At this time, the instruction terminal 4 stores data indicating that the reread is performed in the field of the reread flag of the returned drug inventory table 9.

For drugs whose expiration date was not recognized by the above-mentioned process related to the "reread" button 63 on the drug expiration date registration list screen displayed on the instruction terminal 4, the expiration date is determined by the recognition unit 14 of the returned drug dispensing device 2. Can be reacquired. As a result, the number of drugs subject to expiration date management in the returned drug dispensing device 2 can be further increased, and inadvertent inventory is not generated, and the expiration date is expired without using the drugs that could be used. There is no need to waste money.

Further, for the drug in which the data indicating that the reread has been performed is stored in the field of the reread flag of the returned drug inventory table 9, the returned drug management system and the instruction terminal 4 have the above-mentioned "reread". It is also possible to control not to perform the process related to the button 63. By performing such control, the returned drug management system can avoid unnecessary and useless repetition of the re-reading process (re-recognition process).

In the drug expiration date registration list screen shown in FIG. 14, it is preferable not to display the drugs that have been dispensed or collected on the list in order to prevent the expiration date data from being changed illegally.

2.3.2.3. Discharge permission processing by drug withdrawal setting with unknown expiration date When the various setting buttons 34 are touched (or clicked) on the main screen shown in FIG. 7 (a), various setting screens as shown in FIG. 7 (b) are displayed. A group of setting screen buttons (34a to 34e) for branching are displayed. Here, when the "other setting" button 34c is touched (or clicked), the other setting screen shown in FIG. 16 is displayed. It is possible to control whether or not to withdraw the medicine with unknown expiration date by the "on / off withdrawal of medicine with unknown expiration date" button 160 on the other setting screen shown in FIG. That is, when the "drug with unknown expiration date on / off" button 160 is used to turn on the withdrawal of the drug with unknown expiration date, "the withdrawal of the drug with unknown expiration date is on" is stored in the instruction terminal 4. Drugs related to records whose "expiration date" is unknown in the returned drug dispensing device inventory table 7a stored in the section (for example, the returned drug dispensing device shared setting table in the local database 3) are also subject to the dispensing process. It becomes. Further, when the "drug with unknown expiration date on / off" button 160 is used to set the withdrawal of the drug with unknown expiration date to the "off" state, "the withdrawal of the drug with unknown expiration date is in the off state" is stored in the instruction terminal 4. Drugs related to records whose "expiration date" is unknown in the returned drug dispensing device inventory table 7a stored in the section (for example, the returned drug dispensing device shared setting table in the local database 3) are subject to the dispensing process. Must not be.

In addition, a screen for setting the handling in the dispensing process of the drug whose expiration date (expiration date) is unknown is further prepared. FIG. 17 is a “returned drug setting” screen, which is a screen for setting the handling of any drug having an unknown expiration date (expiration date) in the withdrawal process. In the setting screen button group (34a to 34e) for branching to various setting screens shown in FIG. 7 (b), the "maintenance" button 34e is touched (or clicked), and further, the "return chemical setting" button. When (not shown) is touched (or clicked), the return chemical setting screen shown in FIG. 17 is displayed. When an arbitrary drug is specified and the "Always payout permission" button 166 is selected in the "Expiration date (expiration date) invalid" section on the left side of the screen, the "Drug withdrawal of unknown expiration date" on the other setting screen shown in FIG. Regardless of the state of the "on / off" button 160 and regardless of the state of the "expiration date" of the returned drug dispensing device inventory table 7a, the drug related to the record in the returned drug dispensing device inventory table 7a is dispensed. Be the target.

On the other hand, when the "Payout permission setting support" button 164 is selected in the "Expiration date (expiration date) invalid" section on the left side of the screen, the "Drug withdrawal on / off of unknown expiration date" on the other setting screen shown in FIG. It is determined whether or not the drug related to the record in the returned drug dispensing device inventory table 7a is subject to the dispensing process according to the state of the button 160. Therefore, it is possible to set the returned drug as a collection target, although it is not a payout target.

In this way, it is possible to finely set how to handle a drug having an unknown expiration date in the payout process.

2.3.3. Return permission setting process When the various setting buttons 34 are touched (or clicked) on the main screen shown in FIG. 7 (a), the setting screen for branching to various setting screens as shown in FIG. 7 (b). Button groups (34a to 34e) are displayed. Here, when the "return permission setting" button 34b is touched (or clicked), the return permission setting screen shown in FIG. 18 is displayed. This screen is a screen for setting the medicines that may be returned to the returned medicine dispensing device 2. That is, by setting the conditions for non-returnable chemicals that must not be returned on the setting screen shown in FIG. 18, the user's desired return process can be executed. More specifically, this screen instructs the returned medicine dispensing device 2 in advance to perform the return work for the medicines other than the predetermined medicines (that is, the medicines that are not non-returnable medicines) at the predetermined time zone. It is a screen to give. The screen shown in FIG. 18 is configured to set a "predetermined time zone" at the bottom of the screen. Further, the screen shown in FIG. 18 is configured to set "non-returnable chemicals" at the upper part of the screen. For example, if the check box of "Chemicals exceeding the upper limit" is checked, the chemicals exceeding the "stock upper limit" in the (virtual) cassette are non-returnable chemicals. In addition, if the "Not eligible for withdrawal" check box is checked, among non-implemented drugs other than the mounted drug (that is, "cassette drug"), the drug that is not paid out by the returned drug payout device 2 is a non-returnable drug. Become.

When a time zone is set at the bottom of the screen, the returned drug payout device 2 is instructed to perform the return operation only in that time zone. Further, when the non-returnable medicine is set at the upper part of the screen, the returned medicine dispensing device 2 is instructed to move the non-returnable medicine in the return tray to the NG tray.

FIG. 19 is a flowchart of a return process for a drug on a return tray based on the return permission setting set on the return permission setting screen shown in FIG. First, when the start time set on the return permission setting screen is reached, this process starts (ST81). The recognition unit 14 of the returned medicine dispensing device 2 performs an operation of recognizing the medicines on the return tray one by one (ST82). If the (conditional) setting for the non-returnable drug is not made (ST84 / NO) at the upper part of the return permission setting screen, the returned drug dispensing device 2 stores the drug in the storage unit 15. At the same time, the control unit of the instruction terminal 4 prepares for the subsequent processing (payout processing, collection processing, aggregation processing, etc.), the returned drug payout device inventory table 7a, the returned drug payout device payout table 7b, and the like. Then, a new record is created in each of the returned drug inventory table 9 (in the local database 3) (ST89). Further, the recognition unit 14 of the returned drug dispensing device 2 continues the drug recognition work (ST82).

If there is a (conditional) setting (ST84 / YES) for non-returnable medicines at the top of the return permission setting screen, the control unit of the instruction terminal 4 is a bar recognized by the recognition unit 14 of the returned medicine dispensing device 2. Read the drug master based on the drug code contained in the code (ST85). The control unit of the instruction terminal 4 determines that there is an item (field) data in the drug master that meets the non-returnable condition (ST86 / YES), or that there is another non-returnable condition (ST87 / YES). For example, the returned drug dispensing device 2 transfers the drug to the NG tray. At the same time, the control unit of the instruction terminal 4 sets the NG flag to "1" and writes an NG comment in order to prepare for the subsequent processing (payout processing, collection processing, aggregation processing, etc.), and then returns the product. Records are created in the drug dispensing device inventory table 7a and the returned drug inventory table 9 (in the local database 3), respectively (ST90).

On the other hand, the control unit of the instruction terminal 4 does not meet the non-returnable condition in the item (field) data in the drug master (ST86 / NO), and there is no other non-returnable condition (ST87 / NO). ), The returned drug dispensing device 2 stores the drug in the storage unit 15. At the same time, the control unit of the instruction terminal 4 prepares for the subsequent processing (payout processing, collection processing, aggregation processing, etc.), the returned drug payout device inventory table 7a, the returned drug payout device payout table 7b, and the like. Then, a new record is created in each of the returned drug inventory table 9 (in the local database 3) (ST89). Further, the recognition unit 14 of the returned drug dispensing device 2 continues the drug recognition work (ST82).

The process according to the flowchart shown in FIG. 19 ends when the drug to be recognized by the recognition unit 14 disappears (ST83 · YES) (ST91). Further, the process ends at the end time set in FIG. 18 (ST88 · YES) (ST91).

Due to the return permission setting process by the returned drug management system, there are other places (cold place, powerful drug management warehouse, etc.) for storage management of drugs that should not be stored in the returned drug dispensing device 2. Not only can you be alerted to this, but the medicines that are about to expire, have expired, or are unknown are stored in the returned medicine dispensing device 2, and the medicines that should be stored originally. There is no need to crush the space. As a result, more efficient and correct return processing can be carried out.

2.3.4. Ward registration process When the ward registration button 38 is touched (or clicked) on the main screen shown in FIG. 7 (a), the ward registration screen shown in FIG. 20 is displayed. This screen is a screen for registering the name of the ward of the return source for each return tray accepted in the receiving unit 12 of the returned drug payout device 2. As described above, the receiving unit 12 in the returned drug payout device 2 is configured to accept, for example, a maximum of seven return trays. That is, as shown in the ward registration screen of FIG. 20, the receiving unit 12 includes seven tray receiving shelves. When the return tray is actually installed on each tray receiving shelf, the return tray image is displayed on the left side of the ward registration screen of FIG. 20 correspondingly.

For each displayed return tray, the name of the ward from which the return tray is returned can be selected and registered on the right side of the ward registration screen. The data of the ward name can be combined with the data of each drug returned and stored in a database (for example, the returned drug dispensing device inventory table 7a).

By registering the ward name of the return tray with the returned drug management system, the status of the returned drug for each ward can be grasped quickly and clearly. In particular, the ward name data can be used as statistical data to create specific forms and the like.

2.3.5. Various display processes Various information can be displayed on the main screen shown in FIG. 7 (a). For example, on the left side of the screen, the number of empty tray receiving shelves in the receiving unit 12 of the returned medicine dispensing device 2 (that is, the return tray is not actually installed) is displayed (in FIG. 7A). , As an example, "empty 5" is displayed.). In addition, it is displayed whether or not the medicine has been transferred to the NG tray at the bottom (in the figure, "no medicine" is displayed as an example).

Further, on the right side of the screen, the composition ratio of the medicines stored in the storage unit 15 of the returned medicine dispensing device 2 by size (that is, by S, M, L) is displayed in real tom by a graph. Here, the "composition ratio by size" is the rate occupied by the drug having the corresponding size on the shelf corresponding to each size (S, M, L).

Further, on the main screen shown in FIG. 7A, a suction pad replacement message may be displayed. For example, the date when the rubber suction pad (first suction pad, second suction pad) is attached or replaced in the storage unit of the drug return control device (drug storage control device) 6 is the suction pad. It is remembered as the start date of each use. When a predetermined period (for example, 2 months and 20 days) has elapsed from the start date of use of the adsorption pad, the returned drug management system (drug sorting device) displays the "first adsorption pad (or first adsorption pad (or)" on the main screen of the instruction terminal 4. , The second suction pad) is approaching three months to be replaced. " Further, the returned drug management system (drug sorting device) displays the "first adsorption pad (or first adsorption pad (or)" on the main screen of the instruction terminal 4 after a predetermined period (for example, 3 months) has elapsed from the start date of use of the adsorption pad. Three months have passed to replace the second suction pad). Please replace it immediately. "

Further, in the storage unit of the drug return control device (drug storage control device) 6, the suction nozzle and the suction pad (first suction pad) after the replacement date of the suction pads (first suction pad, second suction pad) are stored. The number of times the nozzle, the first suction pad, the second suction nozzle, and the second suction pad are operated (that is, the number of times the suction pad is sucked) is stored. If the number of operations of the returned drug management system (drug sorting device) exceeds a predetermined number of times (for example, 27,000 times) from the start date of use of the adsorption pad, the "first adsorption pad (or the first adsorption pad (or)" is displayed on the main screen of the instruction terminal 4. , The second suction pad) is approaching 30,000 uses to be replaced. " Further, if the number of operations of the returned drug management system (drug sorting device) exceeds a predetermined number of times (for example, 30,000 times) from the start date of use of the adsorption pad, the "first adsorption pad" is displayed on the main screen of the instruction terminal 4. (Or, the second suction pad) has been used more than 30,000 times to be replaced. Please replace it immediately. "

Further, the recognition unit 14 of the returned drug dispensing device (accommodated drug dispensing device) 2 may include a suction pressure monitor that periodically monitors the suction pressure of the suction pad. Then, when a situation occurs in which the suction pressure of the suction pads (first suction pad, second suction pad) monitored by the suction pressure monitor falls below a predetermined value, the main screen of the instruction terminal 4 displays the "first suction pad (first suction pad). Alternatively, the returned drug management system (drug sorting device) may be configured to display "The suction pressure of the second suction pad) has decreased. Please replace it."

It is preferable that a screen for setting whether or not to display the adsorption pad replacement message on the main screen as described above is constructed by the returned drug management system (drug sorting device) and can be used by the instruction terminal 4. .. Similarly, a screen for setting a predetermined period of use in which the suction pad should be replaced, a predetermined number of operations in which the suction pad should be replaced, and a predetermined minimum suction pressure value in which the suction pad should be replaced is also a returned drug management system. It is preferable that it is constructed by (drug sorting device) and can be used by the instruction terminal 4.

Further, on the main screen shown in FIG. 7A, the inventory status of the cassette drug in the storage unit 15 of the cassette type injection drug dispenser and the returned drug dispenser 2 is displayed by the "cassette drug inventory" button 21b. There is. First, if there is at least one cassette in which the number of stocks is zero, "out of stock" is displayed. Even if there is no cassette corresponding to "out of stock", if there is at least one cassette whose inventory quantity is less than the filling standard amount (stock lower limit) and is 1 or more, "remaining quantity" is displayed. If there is no cassette that corresponds to "out of stock" or "remaining shortage", and the number of stocks is between the maximum mounting amount (stock constant) and the filling standard amount (stock lower limit) for all cassettes. , "Appropriate" is displayed. The inventory information of the cassette in the payout line system 101 may be displayed on the main screen.

2.3.6. Entry / exit history display process On the main screen shown in FIG. 7 (a), the inquiry button 32 is touched (or clicked), and further, the “warehousing / delivery inquiry” button (not shown) is touched (or clicked). Then, the warehousing / delivery inquiry screen (receipt / delivery history screen) shown in FIG. 21 is displayed. If you enter the "extraction condition" on the left side of the screen here, the warehousing data that meets the extraction condition, that is, the list of returned drug data or the warehousing data, based on the data stored in the database 5 and the local database 3 That is, a list of payout data and collection data is displayed. At this time, the number of data included in the list (list of returned drug data conforming to the extraction conditions or list of payout data and collection data conforming to the extraction conditions) is displayed at the lower right of the screen.

On the right side of the warehousing / delivery inquiry screen (receipt / delivery history screen) shown in FIG. 21, a list of warehousing data is displayed. In the list of shipping data, the item of "reason for withdrawal" is displayed. Reasons for withdrawal include "payout" and "instruction collection". The display of the reason for withdrawal is performed based on the data stored in the field of "reason for withdrawal" in the returned drug inventory table 9 of the local database 3. At the time of the payout process, the payout instruction data 87 is generated from the return drug payout device payout table 7b (see FIG. 5 (1)). Data indicating "payout" is stored in the "payout reason" field in the inventory table 9. On the other hand, at the time of collection processing, collection data (dummy prescription data) 90 is generated from the return drug dispensing device collection table 7c (see FIG. 5 (2)), and in response to this, the returned drug management system is a local database. Data indicating "instruction collection" is stored in the field of "reason for withdrawal" in the returned drug inventory table 9 of 3.

As described above, a list of warehousing data is displayed on the right side of the warehousing / delivery inquiry screen (receipt / delivery history screen) shown in FIG. In the displayed list, when one line related to the data of any drug is touched (or clicked), the touched (or clicked) line acquired by the recognition unit 14 of the returned drug dispensing device 2 is displayed. The screen (expiration date registration check) in which the image data including the "expiration date (expiration date)" of the related drug and the "expiration date (expiration date)" data in the returned drug dispensing device inventory table 7a are displayed. The screen) may be displayed. By using this expiration date registration check screen, it is possible to check whether the expiration date data read by the returned drug dispensing device 2 is accurate.

In the list to be displayed, data on drugs that are not in the returned drug dispensing device 2 that has already been paid out or collected is displayed. Therefore, the expiration date read by the returned drug dispensing device 2 for those drugs as well. You can check if the data is accurate. In addition, since such an expiration date registration check screen also displays data on drugs that have already been withdrawn or collected and are not in the returned drug dispensing device 2, in order to prevent the expiration date data from being changed illegally. It is desirable that the expiration date data cannot be changed from this screen for at least the medicines that have already been paid out and are not in the returned medicine dispensing device 2.

2.3.7. Labeling and drug selection for barcodes to which multiple chemicals are assigned Multiple chemicals may be assigned to a single chemical barcode. In that case, the returned drug management system can display a screen indicating that a plurality of drugs are assigned on the instruction terminal 4. Further, on the screen of the instruction terminal 4, one of a plurality of chemicals can be selected. After selection, the returned drug management system will use the selected drug as the drug corresponding to the drug barcode.

2.3.8. Output of drug summary table The payout line system 101 including the returned drug management system can output a form from a printer connected to the network. FIG. 22 shows a drug summary table 70 by ward, which is one of the forms. The drug summary table 70 by ward is a form that aggregates and outputs the drugs paid out from the payout line system 101 for each ward for each payout date. In the table, the number of bottles paid out for each drug is displayed.

In the drug summary table 70 by ward, if the number of drugs paid out by drug includes those paid out from the returned drug payout device 2, a mark (star mark in FIG. 22) 72 indicates that fact. Is shown on the right side of the number of medicines display.

FIG. 23 is a flowchart of a process in which the payout line system 101 including the returned drug management system outputs the drug summary table 70 for each ward based on the payout instruction data 87 output by the drug return control device 6. The returned drug management system sequentially retrieves the withdrawal instruction data 87 after the withdrawal is executed (ST102). With respect to the payout instruction data 87 after the payouts are sequentially taken out, the returned medicine management system aggregates the number of medicines to be paid out for each payout date and ward. At this time, if the medicines to be paid out are included in the medicines to be paid out from the returned medicines paying out device 2, the returned medicines management system stores the "returned medicines available" flag for the medicines to be returned (ST104). When the withdrawal instruction data 87 after the withdrawal is executed is completed (ST103 / YES), the returned drug management system ends the processing related to the aggregation.

Subsequently, the payout line system 101 including the returned medicine management system prints the number of medicines to be paid out for each payout date and ward (ST105). At this time, if the medicines paid out from the returned medicines payout device 2 are included in the number of medicines to be paid out, that is, if the "returned medicines available" flag is stored for the medicines to be printed out. The payout line system 101 including the returned medicine management system prints a mark in the vicinity of the number of medicines to be paid out data (ST107). When the aggregated data of the dispensed chemicals is completed (ST108 · YES), the processing related to printing is completed (ST109).

In this way, in the drug summary table 70 by ward, when the number of drugs paid out by drug includes the one paid out from the returned drug payout device 2, the mark indicating that fact is on the right side of the number display. If indicated in, it becomes clear that the dispensed drug contains the returned drug.

Further, a stick (paper piece) called an "injection slip" showing information on the dispensed medicine may be added to the tray for collecting the medicines dispensed from the payout line system 101. Similar to the above-mentioned ward-specific drug summary table 70, the drug information displayed on this injection sheet can also be marked to indicate that the returned drug is included.

2.3.9. Output of collection rewrite card When the returned drug management system performs a collection operation, the collection rewrite card 74 is attached to the return tray. The rewrite card here is a card in which the display of information such as character information, graphic information, and barcode can be changed by a rewriting device, and a leuco system or a cloudy system can be used. As the recovery rewrite card, electronic paper or a liquid crystal display may be used instead of these types of rewrite cards.

The collection conditions are displayed on the "collection rewrite card" 74 given to the return tray by the payout line system 101 including the returned drug management system. FIG. 24A is a display example of the collection conditions in the collection rewrite card 74.

The returned drug management system grasps the collection conditions with reference to the returned drug dispensing device collection table 7c. For example, fields such as the long-term retention flag and the near-expiration flag are referenced. That is, the extraction conditions input on the chemical recovery screen shown in FIG. 8 (or FIG. 12) are displayed on the recovery rewrite card 74. The recovery rewrite card 74 can be created, for example, in the discharge lifter (with rewrite) 117 in the payout line system 101.

FIG. 24B is a flowchart of the process of outputting the recovery rewrite card shown in FIG. 24A. First, by the collection work of the returned drug dispensing device 2, the control unit of the drug return control device 6 creates a new record in the returned drug dispensing device collection table 7c (ST122). The returned drug management system obtains the reason for collection from the record (ST123). The discharge lifter (with rewrite) 117 prints the reason for the collection on the rewrite card and outputs it together with the tray for collection (ST124).

By clearly displaying the recovery conditions on the recovery rewrite card 74 in this way, the treatment for the drug to be recovered can be immediately grasped. Not only that, mistakes in taking the tray can be prevented, so that mistakes in work after collection are reduced, and at the same time work efficiency is improved.
