Description

  The present invention relates to a system that supports dispensing audits of packaging drugs, and more particularly, to a dispensing audit support system that can be expected to promote prevention of dispensing errors.

  Conventionally, insurance pharmacies, etc., have dispensed medicines based on prescriptions issued by doctors, and then conducted dispensing audits to confirm that the contents of the dispensing (such as the type and quantity of the dispensed medicine) are correct. ing.

  Here, a packaging form called a PTP (Press Through Package) is known as a medicine packaging form, in which a plastic film is molded into a dome shape so that the medicine can enter, and heat sealed with a laminate containing aluminum foil. .

  Dispensing audits for such PTP-packed drugs (hereinafter referred to as PTP-packed drugs) are performed by a pharmacist who conducts the dispensing audit visually confirming the drug name written on at least one of the front and back surfaces of the PTP package. Therefore, the current situation is that only the contents of the prescription are checked and no dispensing audit record is left.

  In this way, the conventional dispensing audit of PTP packaging drugs relies solely on the actual visual inspection of the PTP packaging drugs of the pharmacist who conducts the dispensing audit, and there is no record, so it is sufficient to prevent dispensing errors. Not only can it be said, there is a problem that the mental burden of the pharmacist is also great.

  The present invention has been made to solve such problems of the prior art, and can be expected to promote the prevention of dispensing errors with respect to packaged drugs, and thus dispensing audits that can reduce the burden on pharmacists who perform dispensing audits. The problem is to provide a support system.

In order to solve such a problem, the dispensing audit support system according to the present invention is a dispensing audit support system for supporting a dispensing audit after dispensing a packaged medicine, in which the drug name is described. The image pickup means for picking up at least one of the front and back surfaces of the packaging, the image recognition means for extracting the drug name from the image picked up by the image pickup means, and the control means for performing dispensing inspection, the control means, Dispensing audit is performed by comparing the medicine name extracted by the image recognition means with the prescription data relating to the prescription. In addition, the “drug name” in this specification refers to information that can identify one drug from another drug, such as a drug name, a drug code, a weight, and any combination thereof, in addition to the drug name itself. Used generically.

  In particular, the prescription data is preferably transmitted from a host computer via a communication line.

  Furthermore, the packaging is preferably PTP packaging.

  As described above, according to the dispensing audit support system according to the present invention, it is possible to reliably recognize each packaged medicine that has been dispensed and to collate the contents of the dispensing with the contents of the prescription, and dispense audit records. Therefore, it can be expected to promote the prevention of dispensing errors for packaged medicines, which in turn can reduce the burden on pharmacists who perform dispensing audits.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a block diagram showing a schematic configuration of a dispensing audit support system according to an embodiment of the present invention. As shown in FIG. 1, the dispensing inspection support system 100 according to the present embodiment includes an imaging unit 1, an image recognition unit 21, a display unit 22, a control unit 23, and a printing unit 3. More specifically, the dispensing support system 100 according to the present embodiment has a configuration in which the imaging unit 1, the personal computer 2 in which a predetermined program is installed, and the printing unit 3 are connected to each other by USB connection or the like. The personal computer 2 has functions as the image recognition means 21, display means 22, and control means 23 described above, and also functions as registration means 24 and input means 25.

  The imaging unit 1 is a unit that images at least one of the front and back surfaces of the PTP package in which the drug name is described (this embodiment will be described as imaging the back surface), and the schematic configuration is shown in FIG. In addition, a housing 11 having an optical window 111 provided on a part of the upper surface, an illumination 12 such as a halogen lamp built in the housing 11, and a CCD camera or the like that receives reflected light from the back surface of the PTP package P. Device 13. In such a configuration, the light emitted from the illumination 12 is irradiated onto the back surface of the PTP package P through the optical window 111, and the reflected light is received by the imaging device 13 through the optical window 111, thereby causing the PTP package P to be received. The back surface of is imaged. FIG. 3 shows an image example of the back side of the PTP package taken by the imaging means 1. The imaging means 1 is not limited to the configuration shown in FIG. 2, and various configurations can be adopted as long as the back side of the PTP package on which the drug name is described can be imaged.

  The display unit 22 displays an image captured by the imaging unit 1 and transmitted to the personal computer 2 (in this embodiment, enlarged display at a predetermined magnification). However, it is of course possible to apply a normal monitor.

The image recognition means 21 extracts the drug name from the image picked up by the image pickup means 1, and is a CPU of the personal computer 2 and an image recognition program installed in the personal computer 2 (since it is a known recognition program, its The detailed algorithm is omitted). In the example shown in FIG. 3, the predetermined region S in the image is cut out, and the medicine name (“Claritin 10 mg” in the example shown in FIG. 3) described in the region S is extracted.
In this embodiment, in order to increase the extraction accuracy of the drug name, drug names of various PTP-packed drugs are registered in advance in the registration unit 24 described later, and the image recognition unit 21 stores the drug described in the region S. When extracting the name, the drug name registered in the registration means 21 is used (the extracted drug name candidate and the pre-registered drug name are sequentially matched, and the degree of matching is the highest (the possibility of being applicable) The registered name is the extraction result).

  The printing means 3 prints the extracted medicine names in a unit of one prescription. In this embodiment, the printing means 3 is a journal printer connected to the personal computer 2, but a normal printer is applied. Of course, it is possible.

  As will be described later, the input unit 25 is used to input a medicine name. In this embodiment, the input unit 25 is a keyboard. However, the touch panel type display unit 22 may be used as the input unit 25.

  As described above, the registration unit 24 registers in advance the names of various PTP-packed drugs (names of all drugs handled by the insurance pharmacy in which the dispensing audit support system 100 is installed). An image obtained by imaging the back surface of the package is also registered (a configuration in which only a part of the captured image such as the predetermined region S described above is registered) may be registered. The drug name is registered in the registration unit 24 by key input using the input unit 25. The image is registered in association with the registered drug name (however, images corresponding to all drug names are not registered) and can be displayed on the display unit 22 as appropriate. The image to be displayed on the display means 22 can be searched using the drug name as a search key. In the present embodiment, the registration means 24 is a hard disk built in the personal computer 2, but is not limited to this, and in addition to an external hard disk, smart media, compact flash (registered trademark), It is also possible to use removable storage means such as a memory stick, a PC card, an MO disk, and a floppy (registered trademark) disk.

  In addition to the imaging unit 1, the image recognition unit 21, the display unit 22, and the printing unit 3 described above, the control unit 23 performs operations of the registration unit 24 and the input unit 25 (data input between the units). (Including output operation) and is embodied by a CPU of the personal computer 2 and a control program installed in the personal computer 2.

  Hereinafter, the operation of the dispensing inspection support system 100 having such a configuration will be described more specifically.

  FIG. 4 is a diagram schematically showing an initial screen displayed on the display means 22. When the dispensing inspection support system 100 is activated (the control program of the personal computer 2 is activated), an initial screen as shown in FIG. 4 is displayed, and the “PTP audit” button B1 is pressed to dispense the PTP packaging medicine. The audit control program is activated and a screen as shown in FIG. 5 is displayed. In addition to the “PTP audit” button B1, the initial screen shown in FIG. 4 includes a “master registration” button B2 for registering the drug name and the back side captured image of the PTP package in the registration means 24, and a dispensing audit support system. An “end” button B3 for ending the operation of 100 is displayed.

  FIG. 6 is a flowchart schematically showing the operation of the dispensing audit support system based on the dispensing audit control program. As shown in FIG. 6, by placing the PTP packaging medicine on the casing 11 (optical window 111) (FIG. 2) of the imaging unit 1, the back surface of the PTP packaging is imaged, and the captured image is displayed on the display unit 22. The enlarged image is displayed in the “read image display frame” 221 (FIG. 5) (S1). Therefore, the pharmacist who conducts the dispensing audit can easily check the drug name in the image displayed in the “read image display frame” 221 and can check the name of the PTP packaged drug. It is possible to reliably recognize the PTP packaging drug. In the present embodiment, the image captured by the imaging unit 11 (imaging device 13) is always transmitted to the personal computer 2, and the image displayed in the “read image display frame” 221 is also captured. It will change each time depending on the target.

  Next, the image recognition unit 21 determines whether or not the image captured by the imaging unit 11 is registered in the registration unit 24 (S2). Specifically, by pressing the “determine” button B4 (FIG. 5) displayed on the display unit 22, the captured image is fixed (the image to be determined is determined) and registered with the captured image. The images are registered in accordance with whether or not there is a registered image having a high degree of matching (the detailed description is omitted because a known matching method is applied). It is determined whether or not there is.

  When the image captured by the imaging unit 1 is already registered in the registration unit 24, the image recognition unit 21 extracts the drug name from the image by the method described above, and the extracted drug name is displayed on the display unit 22 “ This is displayed in the “reading drug name display frame” 222 (FIG. 5) (S3).

  Next, by pressing the “OK” button B4 (FIG. 5) of the display means 22 after elapse of 5 seconds or 5 seconds after the medicine name is displayed in the “reading medicine name display frame” 222 (S4). The drug name is additionally displayed in the “read drug name list” 223 (FIG. 5) (S5).

  When the imaging, image display, drug name extraction, and additional display operation to the list 223 for one PTP packaged drug are completed by the series of operations described above, and another PTP packaged drug is included in one prescription, By placing the other PTP packaging medicine on the imaging means 1, a series of operations are repeated ("Yes" in S6).

  In this way, when a series of operations for all the PTP packaging medicines for one prescription is completed (“No” in S6), the “audit complete” button B5 of the display means 22 is pressed (S7). The extracted medicine names are collectively printed in one prescription unit by the printing means 3 (S8). That is, all drug names displayed in the “read drug name list” 223 are printed together. As described above, since the medicine name is automatically extracted from the captured image by the image recognition means 21 and the extracted medicine name is collectively printed for each prescription unit by the printing means 3, the printed matter is checked against the prescription. Thus, it is easy to collate the contents of the dispensing with the contents of the prescription, and the printed matter can be used as a dispensing audit record. In the present embodiment, the printing unit 3 is configured to print a plurality of copies of the extracted medicine names in one prescription unit. Therefore, it is possible to store a part of the printed matter of multiple copies as a dispensing audit record at an insurance pharmacy, etc., while handing out the other part to the patient as a dispensing audit record. The advantage is that you can get a sense of security rather than

  After the medicine name is printed by the printing means 3, by pressing the “audit complete” button B5 again (S9), the display of the “read medicine name list” 223 is erased, and a series of PTP packaging medicines for the next prescription is displayed. Operation starts. When dispensing audits for all prescriptions are completed, an “end” button B6 of the display means 22 is pressed to return to the initial screen shown in FIG.

  Next, the operation when the image picked up by the image pickup means 11 is not registered as a result of determining whether or not the image picked up by the registration means 24 is registered (S2) will be described.

  In this case, first, an error notification is made, that is, a predetermined error message is displayed in the “message display frame” 223 (FIG. 5) of the display means 22 and an error sound is generated ( S10), thereby alerting the pharmacist who conducts the dispensing audit and can take all possible measures to prevent dispensing errors (if the captured image is not registered, the wrong PTP packaging drug is mixed) This may lead to prevention of dispensing errors by notifying this).

  Next, a message and selection buttons (three selection buttons in the present embodiment) for selecting the next operation are displayed in the “message display frame” 223 (S11). Here, when the first selection button is pressed ((1)), the operation starts again from the imaging of the PTP packaging medicine (for example, the position where the PTP packaging medicine is placed is poor and the accuracy of the captured image is good). If not, it is preferable to press the first selection button).

  When the second selection button is pressed ((2)), the screen shifts to a “master registration screen” (the same screen as that displayed when the “master registration” button B2 shown in FIG. 4 is pressed) (S12). On the screen (not shown), it is possible to register the captured image in the registration means 24 (for example, when there is a relatively long time and it is desired to register the image, the second selection is performed). It is preferable to press a button). When the registration operation is completed, the screen returns to the screen shown in FIG. 5. After extracting the medicine name from the captured image and displaying it in the “read image name display frame” 222, “confirm” When the button B4 is pressed (S4), the extracted drug name is additionally displayed in the “read drug name list” 223 (S5), and thereafter, the same operation as when the captured image is registered in the registration means 24 is performed. It becomes.

  When the third selection button is pressed ((3)), a message prompting the user to input the drug name is displayed in the “message display frame” 223 (FIG. 5), and the drug name is input by the input means 25 (S13), By pressing the “confirm” button B4 (S4), the inputted medicine name is additionally displayed in the “read medicine name list” 223 (S5), and thereafter, the captured image is registered in the registration means 24. The operation is the same as in the case (for example, since there is no time allowance, it is preferable to press the third selection button when it is desired to prioritize the dispensing audit over the image registration).

  As described above, since the dispensing inspection support system 100 according to the present embodiment is configured to be able to select an operation when the captured image is not registered, the pharmacist performing the dispensing audit can freely select according to the situation. It has the advantage of high degree of convenience and excellent convenience.

  In the present embodiment, the subject of the dispensing audit is limited to the PTP packaged drug, but the dispensing audit support system 100 can also be used in the dispensing audit of other drugs such as ointments and eye drops. is there. In the present embodiment, the extracted medicine name is collectively printed for each prescription unit by the printing unit 3 and only the example in which the printed matter is collated with the prescription and the dispensing audit is performed has been described. It is also possible to adopt a configuration in which the (personal computer 2) is connected to an appropriate prescription input host computer (not shown) via a communication line. That is, the prescription inputted by the host computer is transmitted to the dispensing inspection system 100 (personal computer 2) via a communication line, and the extracted medicine name (collected for each prescription unit) and the transmitted It is also possible to employ a configuration in which the prescription is automatically collated by the control means 23.

  The dispensing inspection support system includes an imaging unit that images at least one of the front and back surfaces of the PTP package on which a drug name is described, a display unit that displays an image captured by the imaging unit, and a drug from the image Image recognizing means for extracting names, printing means for printing the extracted medicine names in a unit of one prescription, control for controlling operations of the imaging means, the display means, the image recognizing means, and the printing means It can also comprise so that a means may be provided.

  According to such a dispensing audit support system, an image obtained by imaging at least one of the front and back surfaces of the PTP package is displayed on the display means (the display can be enlarged depending on the configuration of the display means). It is easy for the pharmacist to visually check the drug name in the image, and the pharmacist can collate with the actual product of the PTP packaged drug, and can surely recognize each dispensed PTP packaged drug. Further, since the medicine name is automatically extracted from the image by the image recognition means, and the extracted medicine name is collectively printed for each prescription unit, the contents of the dispensing and the prescription can be checked by comparing the printed matter with the prescription. It is easy to check the contents, and the printed matter can be used as a dispensing audit record. As described above, according to the dispensing audit support system, it is possible to reliably recognize each dispensed PTP packaging drug and to compare the dispensing contents with the prescription contents, and to obtain a dispensing audit record. Therefore, it can be expected to promote prevention of dispensing errors with respect to PTP-packed drugs, and as a result, it is possible to reduce the burden on pharmacists who perform dispensing audits.

  Preferably, the apparatus further includes a registration unit in which drug names of various PTP packaging drugs are registered in advance, and the image recognition unit is based on an image captured by the imaging unit and a drug name registered in the registration unit. The medicine name is extracted from the image.

  According to such a dispensing audit support system, drug names of various PTP-packed drugs (for example, all drug names handled by an insurance pharmacy where the dispensing audit support system is installed) are registered in the registration means, and drugs are taken from the captured images. In extracting the name, the drug name registered in the registration means is used. In other words, a drug name registered in advance is used instead of extracting a drug name based only on a captured image (for example, a candidate for an extracted drug name and a pre-registered drug name are sequentially matched). In addition, since the degree of matching is the highest (the registered name having the highest possibility of matching is used as the extraction result), the drug name extraction accuracy can be increased.

  More preferably, an image obtained by imaging at least one of the front and back surfaces of the PTP package is further registered in the registration unit, and the image recognition unit obtains a medicine name from the image captured by the imaging unit. Before extracting, it is determined whether or not the image is registered in the registration unit, and the control unit determines that the image is not registered by the image recognition unit and registers the image. After registering with the means, whether the image recognition means extracts the drug name from the image, or allows the drug name to be input unregistered and handle the input drug name in the same manner as the extracted drug name , At least one of them can be selected.

  According to such a dispensing audit support system, an image obtained by imaging at least one of the front and back surfaces of the PTP package is registered in the registration unit in advance, and whether or not an image captured by the imaging unit is registered (E.g., matching between a captured image and a registered image and determining whether there is a registered image with a high degree of matching). If it is registered, it is possible to adopt a configuration in which an error is displayed on the display means or the like to alert the pharmacist, and it is possible to take all possible measures to prevent dispensing errors. Further, when it is determined that the captured image is unregistered, the drug name is extracted from the image after registering the image in the registration unit, or the drug name is input without registration, It is possible to select at least one of handling the input medicine name in the same manner as the extracted medicine name. That is, after registering an unregistered image in the registration means, normal processing (extracting the drug name) is performed, or when there is no time allowance, the image is not registered and remains unregistered. It is possible to select whether to give priority to the dispensing audit (without extracting the drug name) (if another option is set, the other option can be selected). Provides a highly flexible and convenient system.

  Preferably, the printing unit is configured to print a plurality of copies of the extracted medicine names in a unit of one prescription.

  According to such a dispensing audit support system, since a plurality of copies of the drug name collected in one prescription unit are printed, a part of the printed matter of the plurality of copies is stored as a dispensing audit record at an insurance pharmacy or the like, The department can be handed over to the patient as a dispensing audit record, and the patient can have an advantage that a sense of security can be obtained rather than simply being dispensed and dispensed.

  According to the above dispensing inspection support system, an image obtained by imaging the back surface of the PTP package is displayed on the display means. Therefore, a pharmacist who performs the dispensing audit can easily see the drug name in the image and It is also possible to collate with the actual product, and it is possible to reliably recognize each dispensed PTP packaging drug. Further, since the medicine name is automatically extracted from the image by the image recognition means, and the extracted medicine name is collectively printed for each prescription unit, the contents of the dispensing and the prescription can be checked by comparing the printed matter with the prescription. It is easy to check the contents, and the printed matter can be used as a dispensing audit record. As described above, according to the present invention, since it is possible to reliably recognize each dispensed PTP packaging drug and to compare the dispensing contents with the prescription contents, it is also possible to obtain a dispensing audit record. It can be expected to promote the prevention of dispensing errors with respect to packaged drugs, which in turn can reduce the burden on pharmacists who perform dispensing audits.
