Description

  The present invention relates to an automatic dispensing apparatus that supplies liquid medicine from a plurality of medicine bottles to a prescription bottle in accordance with prescription data and a medicine bottle management method in the automatic dispensing apparatus.

  In the dispensing of liquid medicine, it is common that a pharmacist searches for a corresponding medicine bottle according to a prescription and prepares a plurality of kinds of liquid medicine using a meter glass.

  However, the work of a pharmacist using a meter glass to mix multiple kinds of liquid medicine by eye measurement is very complicated, and the work efficiency is low and inefficient.

  In view of such points, for example, Patent Document 1 proposes a liquid medicine automatic dispensing machine in which liquid medicine is automatically prepared.

JP 2003-325639 A

  In the liquid medicine automatic dispensing machine disclosed in Patent Document 1, the user (pharmacist) places a plurality of medicine bottles on the index rotary base, but the user does not know the order of placing medicine bottles. It becomes the composition which does not become. Therefore, when the medicine bottle is placed at the wrong position, there is a possibility that desired dispensing will not be performed.

  In particular, in an automatic dispensing machine, since the pharmacist leaves the drug bottle after setting the drug bottle, the chance of visually checking the drug bottle is reduced compared to the pharmacist himself dispensing. Therefore, a function for automatically identifying the medicine bottle set in the automatic dispensing machine is required in order to prevent a mistake in the medicine bottle. In the future, even the process of setting a medicine bottle in an automatic dispensing machine may be automated, but in that case, a function for automatically identifying the medicine bottle is required.

  Furthermore, until now, the expiry date of the liquid medicine in the medicine bottle set in the automatic dispensing machine and the amount of remaining liquid had to be confirmed every time the pharmacist himself used the medicine bottle. For example, it is good to know that the amount of liquid remaining in the medicine bottle is seemingly small compared to the amount described in the prescription, but if it is subtle or not, it was still insufficient after the end of automatic dispensing It can also be.

  The present invention has been made in view of the above points, and can automatically identify a medicine bottle set in an automatic dispensing device, and whether or not the expiration date and the amount of remaining liquid are also suitable. The purpose is to enable automatic determination.

The automatic dispensing device according to the present invention is an automatic dispensing device that supplies liquid medicines from a plurality of medicine bottles to a medicine bottle according to prescription data, and is provided in each medicine bottle and has information specific to each medicine bottle. A recording medium for recording the information, an information acquisition means capable of acquiring information from the recording medium of each medicine bottle, and a medicine bottle set in the automatic dispensing device based on the information obtained by the information acquisition means It is characterized in that it is provided with information processing means for identifying.
A medicine bottle management method in an automatic dispensing apparatus according to the present invention is a medicine bottle management method in an automatic dispensing apparatus that supplies liquid medicine from a plurality of medicine bottles to a prescription bottle in accordance with prescription data. It is characterized in that, at the time of opening, a code in which information peculiar to each medicine bottle is coded is printed on a label, and the label is attached to the medicine bottle.

  According to the present invention, it is provided with a recording medium that is provided in each medicine bottle and records information specific to each medicine bottle, and an information acquisition unit that can obtain information from the recording medium of each medicine bottle. Therefore, the medicine bottle set in the automatic dispensing device can be automatically identified, and the mistake of the medicine bottle can be prevented.

  In addition, if the information on the expiration date is included in the information specific to each medicine bottle, or if the information processing means has information on the expiration date of each medicine bottle in advance, the water in the medicine bottle set in the automatic dispensing device It is also possible to automatically determine whether the expiration date of the medicine is appropriate.

  In addition, the information processing device manages the amount of used liquid in each medicine bottle and includes information on the amount of liquid at the time of opening in the information specific to each medicine bottle. If information on the amount of liquid is stored in advance, it is possible to automatically determine whether or not the remaining amount of liquid in the medicine bottle set in the automatic dispensing device is appropriate.

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.
(First embodiment)
As shown in FIG. 1, the automatic dispensing device 100 of the present embodiment supplies liquid medicine from a plurality of medicine bottles 300 to a prescription bottle 400 according to prescription data and prepares the information processing means referred to in the present invention. An information processing apparatus 200 such as a personal computer provided with an input device 201 and a display device 202 is connected.

  In the information processing apparatus 200, as will be described in detail later, a medicine bottle identifying unit 200a for identifying the medicine bottle 300 set in the automatic dispensing apparatus 100 in combination with a CPU, a RAM, a ROM, and the like. It functions as an expiry date confirmation unit 200b for confirming the expiry date of the liquid medicine, a use history management unit 200c for managing the use history in the automatic dispensing device 100 including information on the used liquid amount of each medicine bottle 300, and the like.

  Here, as shown in FIG. 1, a label 500 on which a two-dimensional code (QR code) is printed is attached to the lower part of the side surface of each medicine bottle 300 set in the automatic dispensing device 100. This two-dimensional code includes the drug name, manufacturer name, lot information, opening date (may be included up to the hour and minute), liquid volume at the time of opening (bottle size), opened pharmacist name, expiration date (expiration date before opening) And / or expiration date after opening) is encoded.

  As shown in FIG. 2, when the pharmacist opens the medicine bottle 300, the pharmacist stores information on the medicine name, manufacturer name, lot information, opening date, amount of liquid at the time of opening, the name of the opened pharmacist, and the expiration date in the personal computer 600 input. The personal computer 600 encodes the input information and causes the printer 700 to output a label 500 on which the two-dimensional code is printed. The pharmacist attaches the label 500 output from the printer 700 to a previously designated location (in this example, the lower side of the side surface) of the opened medicine bottle 300. The personal computer 600 may be the information processing apparatus 200 shown in FIG. 1 or a personal computer different from the information processing apparatus 200.

  Of the information input to the personal computer 600, for example, the expiration date before opening may be specified mainly by the manufacturer, and that information may be used. The expiration date after opening may be specified by the user (pharmacist). Basically, the pharmacist only has to manually input each information into the personal computer 600. For example, the drug name and manufacturer name can be obtained by reading a barcode printed on the medicine bottle 300 or its package on the manufacturer side. You may make it input into the personal computer 600. FIG.

  With reference to FIG. 1, the automatic dispensing apparatus 100 of this embodiment is demonstrated. The automatic dispensing apparatus 100 contains a turntable 101 on which a plurality of medicine bottles 300 can be placed in a circumferential direction, an electronic balance 102 on which a prescription bottle 400 can be placed, and purified water. And a table 103 on which the diluted liquid container 800 can be placed. The turntable 101 can be rotated by a stepping motor (not shown) to place a desired medicine bottle 300 at the supply position.

  Each drug bottle 300 and diluent container 800 are covered with a lid 105 with a pipette tip 104. The lid 105 with the pipette tip 104 is connected to a pump 108 via a tube 106 and an on-off valve 107. In the figure, reference numeral 109 denotes a joint for collecting the tubes 106 together.

  A θ-Z drive mechanism 110 is disposed at a position surrounded by the turntable 101, the electronic balance 102, and the table 103. The θ-Z drive mechanism 110 includes a rotating shaft 110a and an arm 110b extending in the horizontal direction. The rotating shaft 110a is rotated together with the arm 110b (θ driving), and the arm 110b is moved up and down along the rotating shaft 110a. (Z drive). At the tip of the arm 110b, for example, a lid holding mechanism 110c configured to sandwich the lid 105 with a pair of claws is configured.

  As shown in FIG. 1A, the medicine bottle 300 on the turntable 101 in the supply position, the prescription bottle 400 on the electronic balance 102, and the diluent container 800 on the table 103 are the arms of the θ-Z drive mechanism 110. The relationship is located on the rotation locus R at the tip of 110b.

  Further, a two-dimensional code reader 111 composed of a CCD camera or the like is installed near the base of the θ-Z drive mechanism 110. The two-dimensional code reader 111 is configured to read the two-dimensional code of the label 500 attached to the medicine bottle 300 on the turntable 101 that has come to the supply position. This two-dimensional code reader 111 obtains information specific to each medicine bottle 300, that is, information on the medicine name, manufacturer name, lot information, opening date, amount of liquid at the time of opening, the name of the opened pharmacist, and the expiration date. can do.

  In the automatic dispensing by the automatic dispensing apparatus 100 as described above, the pharmacist inputs prescription data (which liquid medicine is used in what amount) from the input device 201 according to the prescription and is necessary on the turntable 101. The medicine bottle 300 is placed. In this case, as shown in FIG. 1 (b), the label 500 attached to each medicine bottle 300 faces the outside in the radial direction of the turntable 101.

  Thereafter, when an instruction to start automatic dispensing is given, the turntable 101 is rotated to place the medicine bottle 300 containing the liquid medicine to be prepared at the supply position. The lid 105 of the vial 300 is held by the lid holding mechanism 110c in a state where the vial containing the liquid medicine to be prepared has come to the supply position. Further, by opening the on-off valve 107 corresponding to the medicine bottle 300 that has come to the supply position, closing the other on-off valve 107 and driving the pump 108, the pipette tip 104 sucks the indicated amount of liquid medicine from the medicine bottle 300. To do.

  After sucking the liquid medicine, the arm 110b is raised, and the pipette tip 104 is completely retracted from the medicine bottle 300 as shown in FIG. Then, the rotating shaft 110a is rotated 90 degrees clockwise in FIG. 1A, and the pipette tip 104 is positioned above the prescription bottle 400, and then the arm 110b is lowered. When the tip of the pipette tip 104 is located in the prescription bottle 400, the liquid medicine is discharged from the pipette tip 104 to the prescription bottle 400 by driving the pump 108.

  When the liquid medicine is discharged from the pipette tip 104 to the prescription bottle 400, the amount of liquid medicine discharged to the prescription bottle 400 is measured by the electronic balance 102. In the present embodiment, the electronic balance 102 is used, but the prescription bottle 400 is imaged from the side by a CCD camera, and the change in the liquid level in the prescription bottle 400 is captured to discharge the prescription bottle 400. You may make it measure the quantity of the liquid medicine to be performed.

  After the liquid medicine is discharged, the arm 110b is raised again, and the pipette tip 104 is completely retracted from the prescription bottle 400. Then, after rotating the rotating shaft 110a by 90 degrees counterclockwise in FIG. 1A, the pipette tip 104 is positioned above the original medicine bottle 300, and then the arm 110b is lowered to cover the lid 105. .

  By repeating the above-described operation for each medicine bottle 300 and the diluent container 800 as required, automatic dispensing is completed.

  Hereinafter, with reference to the flowchart of FIG. 3, an example of the processing operation in the automatic dispensing apparatus 100 of the present embodiment will be described. As described above, when automatic dispensing is performed by the automatic dispensing apparatus 100, the pharmacist inputs prescription data (which liquid medicine is used in what amount) from the input device 201 according to the prescription and is necessary on the turntable 101. A suitable medicine bottle 300 is placed.

  Thereafter, when an instruction to start automatic dispensing is given, before actually starting automatic dispensing, the information processing apparatus 200 first rotates the turntable 101 to label all medicine bottles 300 on the turntable 101. The two-dimensional code reader 111 reads 500 two-dimensional codes (step S101). As a result, the information processing apparatus 200 acquires, for each medicine bottle 300, information on medicine name, manufacturer name, lot information, opening date, amount of liquid at the time of opening, the name of the opened pharmacist, and the expiration date. Can be identified (specified).

  In addition, information on the medicine name, manufacturer name, lot information, opening date, amount of liquid at the time of opening, the name of the opened pharmacist, and the expiration date for each medicine bottle 300 is displayed on the display device 202 (step S102). Thereby, the medicine bottle 300 set by the pharmacist can be confirmed.

  Furthermore, the information processing apparatus 200 determines whether or not all the medicine bottles 300 (liquid medicine) necessary for dispensing are prepared by comparing the medicine name acquired from the two-dimensional code with the prescription data (step S103). As a result, if all the medicine bottles 300 are prepared, the process proceeds to step S105 as it is, and if all the medicine bottles 300 are not prepared, the medicine bottle 300 necessary for the display device 202 is not placed on the turntable 101. Notification display is performed (step S104). After the pharmacist resets the medicine bottle 300 in accordance with the notification, the process starts again from step S101.

  In step S105, the expiration date acquired from the two-dimensional code is compared with the current date and time to determine whether or not the liquid medicine in each medicine bottle 300 is within the expiration date. As a result, if the liquid medicine in each medicine bottle 300 is within the expiration date, the display device 202 displays a notification indicating that the expiration date has passed if there is one that has passed the expiration date. This is performed (step S106). After the pharmacist replaces the medicine bottle 300 whose expiration date has passed in accordance with the notification with a medicine bottle 300 within the expiration date (for example, a new medicine bottle), the processing is started again from step S101.

  In step S107, it is determined whether or not there is a usage history for each medicine bottle 300. As described above, the automatic adjustment device 100 measures the amount of liquid medicine (that is, the supply amount (= used liquid amount) from the medicine bottle 300) discharged to the prescription bottle 400 by the electronic balance 102. Information on the used liquid amount is also transmitted to the information processing apparatus 200, and is stored and managed as a use history of the medicine bottle 300 in association with the information group acquired from the two-dimensional code. If a certain medicine bottle 300 is used several times, the used liquid amount at each time is stored.

  When there is no usage history of the medicine bottle 300, that is, when the medicine bottle 300 is set in the automatic dispensing device 100 for the first time after opening, the usage history of the medicine bottle 300 is newly set (step S108). The process proceeds to step S111.

  On the other hand, if there is a usage history of the medicine bottle 300, it is necessary for the dispensing described in the prescription data by comparing the amount of liquid at the time of opening obtained from the two-dimensional code with the amount of used liquid in the usage history It is determined whether or not a sufficient amount of liquid remains in the medicine bottle 300 (step S109). As a result, if the liquid amount necessary for the dispensing described in the prescription data remains in all the medicine bottles 300, the liquid amount necessary for the dispensing described in the prescription data is directly transferred to step S111. If there is something that does not remain, a notification indicating that the remaining liquid amount is insufficient is displayed on the display device 202 (step S110). According to the notification, the pharmacist replaces the medicine bottle 300 having a short remaining liquid amount with a medicine bottle 300 having a sufficient residual liquid amount (for example, a new medicine bottle), and then starts the process again from step S101.

  As described above, when steps S101, S105, S107, and S109 are cleared, automatic dispensing by the automatic dispensing apparatus 100 is actually started (step S111). Since the medicine bottle 300 on the turntable 101 is identified in step S101, the turntable 101 can be rotated so that the necessary medicine bottles 300 are sequentially positioned at the supply position according to the prescription data.

  As described above, the medicine name, manufacturer name, lot information, opening date, amount of liquid at the time of opening, the name of the opened pharmacist, and the expiration date for each medicine bottle 300 are displayed on the display device 202. The pharmacist is notified by automatically determining whether all the medicine bottles 300 necessary for dispensing are available, within the expiration date, or whether the amount of liquid necessary for dispensing remains in the medicine bottle 300. The desired formulation can be carried out.

(Second Embodiment)
In the first embodiment, an example of using a two-dimensional code that can encode a large amount of information has been described. However, for each medicine bottle 300, a label 500 attached to each medicine bottle 300 is used. You may make it print unique information, for example, the one-dimensional code which coded the number.

  In this case, the drug name, manufacturer name, lot information, date of opening, amount of liquid at the time of opening, name of the opened pharmacist, and expiration date are separately input to the information processing apparatus 200 and stored in advance in the information processing apparatus 200. Every database bottle 300 is associated with unique information (the same as the coded information) and stored in a database.

  As mentioned above, although this invention was demonstrated with embodiment, this invention is not limited only to embodiment, A change etc. are possible within the scope of the present invention. For example, the configuration of the automatic dispensing device 100 of the above embodiment is an example, and any configuration may be used as long as liquid medicine is supplied from a plurality of drug bottles to a prescription bottle according to prescription data. Good.

  In the above embodiment, an example in which the automatic dispensing device 100 and the information processing device 200 are separate bodies has been described. However, the automatic adjustment device 100 may be integrated with an information processing unit having the function of the information processing device 200. Absent.

  In the above embodiment, the two-dimensional code or the label 500 printed with the one-dimensional code is described as an example of the recording medium of the present invention. For example, information unique to each medicine bottle 300 is written in the RFID tag, A tag may be hung on each medicine bottle 300. In this case, the automatic dispensing device 100 is provided with a wireless receiving device instead of the code reader.

It is a figure which shows the structure of the automatic dispensing apparatus of this embodiment.
