Description

  The present invention relates to a drug audit support device, and more particularly to a device that supports an audit of one or more solid drugs sealed in a drug package.

  In hospitals and pharmacies, pharmacists do dispensing according to prescriptions created by doctors. A pharmacist will audit the drug after dispensing. In many cases, prescriptions are instructed to take multiple drugs at once. In such a case, it is convenient if a batch is stored in a single bag, and mistakes in taking can be prevented or reduced. Therefore, a single-packaging device (packaging device) that automatically packs a plurality of solid medicines (tablets, capsules, etc.) to be taken at one time has been put into practical use. The exterior of a medicine package (packaging bag) corresponding to such a dosage unit is generally composed of a resin film having transparency.

  After being packaged as described above, an audit is required to confirm that one or a plurality of drugs enclosed in individual drug packages are configured as prescribed. This is because there is a possibility that an error has occurred in the medicine composition in each medicine package due to an error in the packaging command to the packaging apparatus, a wrong medicine, or the like. In view of this, an audit support apparatus has been proposed in which a medicine package is imaged, an image is acquired, and the medicine is automatically analyzed by analyzing the image (Patent Documents 1-4). Even if a pharmacist finally conducts a visual inspection, if automatic inspection is performed automatically prior to that, it can respond quickly when inappropriate packaging occurs, or the burden on the audit can be reduced. Because.

Japanese Patent No. 2879129 Japanese Patent No. 4300809 JP 2000-135268 A JP-A-9-299448 JP 2007-198802 A JP 2010-172672 A

  However, some drugs have similar sizes, shapes, colors, and the like, and there is a possibility that misperception may occur when an inspection is performed using only an image. Therefore, it is desirable to use another inspection (secondary inspection) in addition to the primary inspection using images. In that case, there is a request to conduct a secondary inspection promptly.

  For example, if a secondary test is performed on all drugs that have undergone a primary test, the overall test time may become unnecessarily long. For example, some drugs can obtain test results that are sufficiently reliable even with only a primary test. If the secondary inspection is performed up to such a medicine, the inspection time is unnecessarily prolonged, which is not desirable. Further, in the secondary examination, specifying the position of each drug anew also causes the examination time to be prolonged.

  Patent Document 5 discloses a medicine identification device that performs an inspection using an image and an inspection using a terahertz wave. The paragraph 0025 describes that a drug position is obtained by image analysis and a terahertz wave is irradiated there. The document describes only vaguely the device configuration and operation contents, and does not describe a configuration that increases the processing speed, including performing a secondary test only for drugs that have not been verified in the primary test. Also, it does not describe how to use location information specifically. Patent Document 6 discloses a technique for inspecting a drug using a near-infrared spectrum, but does not describe cooperation with an image inspection.

  Accordingly, an object of the present invention is to provide a drug audit support apparatus that can achieve both improvement in test accuracy and improvement in processing speed in drug audit support.

  The drug audit support device of the present invention is a drug audit support device that supports auditing of a solid drug sealed in a drug package, transports the drug package in the transport direction, and transports it to a specified inspection position. Based on the image obtained by imaging the medicine bag with the medicine package transporting means and the imaging means, the primary inspection is performed on the medicine in the medicine package, and the medicine to be subjected to the secondary inspection based on the image A characteristic of the drug is acquired by a primary inspection means for calculating a position and a probe close to the drug to be subjected to the secondary examination, and secondly for the drug to be subjected to the secondary examination based on the acquired characteristic. A secondary inspection means for performing a secondary inspection; and a transfer means for transporting the probe to a position close to the medicine to be subjected to the secondary inspection, based on the position calculated by the primary inspection means. Transfer position Characterized in that it comprises a transfer means for constant, the.

  In a preferred aspect, the primary examination means identifies a drug whose drug type could not be identified by analyzing the image as a drug to be subjected to a secondary examination. In another preferred aspect, the apparatus further comprises distance measuring means for measuring a distance to the medicine to be subjected to the secondary examination, and the transfer means is the position calculated by the primary examination means, and the measured Based on the distance, the transfer position of the probe is determined.

  In another preferred aspect, the probe is a spectroscopic probe that irradiates a medicine to be subjected to a secondary examination with light supplied from a light source, receives reflected light from the medicine, and sends the reflected light to a spectrometer. The probe, the light source, and the spectroscope are fixedly installed on a single inspection head and move together with each other, and the light source is installed on the opposite side of the spectroscope with the probe interposed therebetween. In another preferred embodiment, the medicine package is supplied in a state of a medicine package sheet in which a plurality of medicine packages are connected in a row, and the medicine inspection support device further includes the medicine package when the medicine package is completely conveyed. A sheet pressing means is provided that prevents a further movement of the medicine package sheet by pressing a part of the packaging sheet, and releases the pressing when the medicine package is transported to allow movement of the medicine package sheet including the medicine package.

  In another preferred aspect, the imaging apparatus and the probe are fixed to a single inspection head, and the transfer means moves the inspection head to move the probe and the imaging means integrally. To do. In this case, the inspection head further includes holding means for holding the medicine package, and the transfer means transports the medicine package by moving the inspection head while holding the medicine package with the holding means. It is desirable to function as well.

  According to the present invention, since the primary inspection and the secondary inspection are executed at the same inspection position, the transfer position of the probe used in the secondary inspection can be determined based on the medicine position calculated by the primary inspection means. As a result, the time required for the secondary inspection can be greatly shortened, and both the inspection accuracy and the processing speed can be improved.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the overall configuration of a medicine inspection support apparatus according to an embodiment of the present invention. 2 is a perspective view of the medicine inspection support apparatus, FIG. 3 is a perspective view of the inspection head as viewed from above, and FIG. 4 is a perspective view of the inspection head as viewed from below. 3 and 4, the illustration of a cover 31 to be described later is omitted.

  This drug audit support device is a device for supporting a drug audit by a pharmacist, and is installed in a pharmacy or a hospital drug department. This medicine inspection support device is connected to a hospital network, for example.

  In FIG. 1, a medicine package sheet 12 is placed on the transport table 10. This medicine package sheet 12 is created by a packaging device and includes a plurality of medicine packages 14 arranged in the transport direction. Each medicine package 14 is a sachet in which one or more medicines are placed. The inside of the medicine package 14 is an airtight space, and each medicine package 14 has a medicine 20. They are tablets as tablets, capsules and the like. In addition, the medicine package sheet 12 may be provided as it is from the packaging device to the medicine inspection support device, or the medicine package sheet 12 may be fed onto the transport table 10 from the supply unit. Each medicine package 14 is made of a transparent resin film. FIG. 5 shows a top view of the medicine package sheet 12.

  The transport table 10 is a base on which the medicine package sheet 12 is placed. Here, in FIGS. 1 and 2, the left side is the upstream side, and the right side is the downstream side. The medicine package sheet 12 is stepped from the upstream side toward the downstream side. As shown in FIG. 2, the transport table 10 is provided with a rail 22 that guides the movement of the medicine package sheet 12, a retracting groove 23 that is a recess for retracting a suction pad 46 described later. In addition, a stocker 24 is provided at the downstream end of the rail 22 to receive the medicine package 14 that has finished the inspection and falls from the rail downstream end. The stocker 24 is a substantially L-shaped metal fitting, and the medicine package 14 that has fallen due to gravity is folded and stored. In addition, at the upstream end of the rail 22, a seat pressing bar 21 that can be raised and lowered is provided. The sheet presser bar 21 is a bar that inhibits further movement of the medicine pack sheet 12 by pressing the medicine pack sheet 12 stepped from the upstream side to the downstream side onto the transport table 10. That is, when the medicine pack 14 that has been inspected falls on the stocker 24 due to gravity, the subsequent medicine pack 14 may move downstream due to the momentum of the drop. In the present embodiment, in order to prevent the subsequent movement of the medicine pack 14, a sheet pressing bar 21 that presses a part of the medicine pack sheet 12 onto the transport table 10 is provided. The sheet pressing bar 21 rises and releases the pressing of the sheet 12 when the medicine package sheet 12 is stepped downstream.

  An inspection station 36 is set on the carriage 10, and a primary inspection and a secondary inspection described later are performed at the inspection station 36. The inspection station 36 is provided with a backlight 28 below the medicine pack 14 positioned there. The backlight 28 is an illumination member that is turned on when a silhouette image is taken, and is embedded in the transport base 10.

  An inspection head 29 is provided above the inspection station 36. The inspection head 29 is a part on which various devices used for inspection such as the camera unit 32, the suction pad 46, the distance sensor 48, and the probe 40 are mounted. The inspection head 29 is attached to an XYZ moving mechanism 50 that can move in three directions of XYZ, and is movable in three dimensions. This XYZ moving mechanism 50 is for transferring the inspection head 29, and consequently the camera unit 32 and the like mounted on the inspection head 29 in accordance with an instruction from the main controller 68. And it functions as a transfer means for transferring the probe 40.

  The inspection head 29 includes a base plate 30 and a cover 31 that covers the base plate 30. A vent 31a is provided in the vicinity of the light source 42 described later in the cover 31. A fan (not shown) is provided in the vicinity of the vent 31a so that heat generated from the light source 42 can be efficiently released to the outside.

  As shown in FIG. 4, the camera unit 32, the distance sensor 48, and the probe 40 are arranged in a line in the transport direction, and the suction pad 46 is installed on the back side of the camera unit 32 and the like. Yes. More specifically, the suction pad 46 is positioned so as to be positioned directly above the retraction groove 23 when the camera unit 32, the distance sensor 48, and the probe 40 are positioned directly above the medicine package sheet 12. Is provided. Further, the protruding amount of the suction pad 46 from the base plate 30 is a protruding amount that can be accommodated in the retreat groove 23 when the probe 40 is brought close to the medicine.

  The camera unit 32 includes a camera 33 and a lighting fixture 34 installed side by side in the Z-axis direction. When performing color imaging, the luminaire 34 irradiates the medicine package 14 with light from above. The camera 33 is an imaging unit having an imaging area that covers the entire medicine package 14. Image data output from the camera 33 is output to the image analysis unit 64. As will be described later, in the primary examination, individual drugs are identified in the data by image analysis, the shape and color are recognized for each individual drug, and matching with the management information on the database is performed. The drug name is identified. However, since there are some drugs that cannot be identified unless a more detailed examination is performed, or because there are cases where identification cannot be performed due to some deficiencies, such drugs are regarded as secondary examination target drugs. In the primary examination, the center point coordinates (drug position) of the secondary examination target medicine are also calculated.

  The suction pad 46 sucks and holds the medicine package 14. By moving the inspection head 29 in the transport direction while the medicine package 14 is sucked and held by the suction pad 46, step feeding of the medicine package 14 is realized. As will be described in detail later, in the secondary examination, the suction pad 46 is also lowered together with the examination head 29 in order to bring the probe 40 close to the medicine to be examined. At this time, in order to prevent interference between the suction pad 46 and the transport table 10, the retreat groove 23 is formed in the transport table 10.

  The probe 40 irradiates the medicine 20 to be inspected with light and receives the reflected light for the secondary inspection. In the present embodiment, the probe 40 irradiates near infrared light, for example, near infrared light having a band of 900 to 1700 nm. However, as a matter of course, other light or visible light may be used. In addition, other measurement waves such as microwaves may be used as long as individual scrutiny can be performed.

  Mounted on the upper surface of the base plate 30 are a light source 42 that supplies light to the probe 40 and a spectroscope 44 that separates reflected light received by the probe 40 and obtains a spectrum. The spectroscope 44 generates a spectrum of diffuse reflected light and outputs the spectrum to the spectrum analysis unit 66. The spectrum analysis unit 66 generates a profile by repeating the differential processing twice for the obtained spectrum and outputs the data to the main control unit 68.

  Both the light source 42 and the spectroscope 44 are optically connected to the probe 40 via an optical fiber. Here, if the shape of the optical fiber, in particular, the optical fiber that transmits the received light signal of the reflected light, or the routing route is fluctuated, the spectral result may be affected. Therefore, in the present embodiment, the positions of the probe 40 and the spectroscope 44 are fixedly set on the base plate, in other words, consideration is given so that the shape of the optical fiber does not change carelessly.

  In general, a relatively large amount of heat is generated from the light source 42. When the optical system of the spectroscope 44 is affected by such heat, it causes instability of the baseline. Therefore, in the present embodiment, the light source 42 is installed on the opposite side of the spectroscope 44 with the probe 40 interposed therebetween, and the spectroscope 44 and the light source 42 are separated as much as possible. Further, as described above, the fan and the vent 31a are provided in the vicinity of the light source 42 so that heat generated from the light source 42 can be efficiently discharged to the outside.

  The distance sensor 48 is a sensor that measures the distance to the medicine 20 that is the subject of the secondary inspection in a non-contact manner. The distance detected by the distance sensor 48 is sent to the main control unit 68 and used for position control of the probe 40 in the secondary inspection. In other words, it is desired that the probe 40 be brought close to the target medicine 20 in the secondary examination. In order to appropriately bring the probe 40 close to the medicine 20, it is necessary to acquire not only the horizontal position of the medicine 20 but also the thickness (vertical position) of the medicine 20. Therefore, in the present embodiment, prior to the secondary examination, the distance between the examination head 29 and the medicine 20 to be subjected to the secondary examination (and hence the thickness of the medicine 20) is acquired, and the obtained distance information is included in the obtained distance information. Based on this, the amount of movement of the probe 40 (inspection head 29) in the Z direction is determined.

  The main control unit 68 performs operation control of each component shown in FIG. 1, and the main control unit 68 performs a substantial part of the primary inspection and the secondary inspection. A database 70 as a storage unit is connected to the main control unit 68, which stores a list of medicines to be prescribed. The type, shape (including thickness), size, and color of each medicine. Various types of information such as ingredients are managed. It is used in the verification described later. Prescription data given from the main system is input to the main control unit 68, and when a medicine is specified as a collation result, the medicine and the medicine described in the prescription data are compared. If it does not match, an error will be certified. In other words, the audit support consists of an audit for identifying the medicine itself in the medicine package and an audit for checking the match with the prescription data. A display unit 72 is connected to the main control unit 68, and when an error or the like occurs, a predetermined display is made on the display unit 72. In addition, it may be recorded as an audit record on a database.

  When performing the primary examination, the main control unit 68 performs collation with the database 70 based on the analysis result by the image analysis unit 64, and performs the position calculation of the medicine 20 as described above. In the secondary inspection, the main control unit 68 executes a calculation for comparing the profile with the profile on the database 70. The main control unit 68 is preferably composed of a CPU, a hard disk, a memory, etc. storing an operation program.

  Next, the principle of the primary inspection and the secondary inspection will be briefly described. The primary inspection is an inspection performed by analyzing an image obtained by imaging with the camera 33 as described above. FIG. 6 is a conceptual diagram of this primary inspection. Reference numeral 90 indicates a silhouette image, which is an image acquired in a state where the above-described backlight is turned on to enhance contrast. Although the image itself may be a color image, a monochrome image is sufficient because the property as a binarized image is used here. The outline of each medicine is extracted based on such a silhouette image. From such an outline, the shape and size of each medicine can be specified. However, when a plurality of drugs are observed in a row on the image, a labeling process for separating them may be applied.

  On the other hand, in FIG. 6, the code | symbol 92 has shown the color image. This is an image obtained by irradiating light from above the target medicine package and imaging the state of one or a plurality of medicines present in the medicine package, including their colors.

  The shape, size, and color of each medicine can be specified from the information of the silhouette image 90 and the color image 92, and the medicine type (tablet / capsule) and the medicine position (center coordinates) can be determined from the outline of each medicine. ) Can be specified. This is represented as an image diagram indicated by reference numeral 94. The code | symbol 96 represents the information specified about the chemical | medical agent A, the code | symbol 98 and the code | symbol 100 represent the information specified about the chemical | medical agent B and the chemical | medical agent C, respectively.

  Next, the principle of the secondary inspection will be briefly described. FIG. 7 is an example of a spectrum obtained by the secondary inspection. The horizontal axis represents the wavelength, and the vertical axis represents the light intensity. In FIG. 7, reference numeral 86 represents, for example, five measurement results for a certain medicine A, and reference numeral 88 represents, for example, five measurement results for another medicine B. For each drug, the spectral spectrum has a unique shape. However, when comparing the spectrum registered on the database with the actually measured spectrum, there is a possibility that accurate matching cannot be performed due to various factors. The second derivative has been performed.

  FIG. 8 shows the spectrum after the second derivative has been performed. Reference numeral 86A shows a profile after applying the second derivative to the spectral spectrum 86 shown in FIG. 3, and similarly, reference numeral 88A shows the result after applying the second derivative to the spectral spectrum 88 shown in FIG. Represents the profile. According to such processing, it is possible to cancel the offset amount and to recognize only the feature of the change remarkably, so that it is possible to further improve the drug discrimination.

  If the profile after the second derivative application is obtained, the main control unit 68 compares the acquired profile with the profiles of various drugs recorded in the database 70 to identify the type of drug to be examined.

  Here, in the present embodiment, in view of the fact that in the secondary examination, the drug must be individually measured using the probe 40, and therefore it takes time to position and move the probe 40, Only drugs that have been determined to require scrutiny in the primary test are included in the secondary test. Therefore, if collation is completed for all drugs in the primary examination, the secondary examination target is zero, and in this case, the secondary examination is not performed. On the other hand, when one or a plurality of secondary examination target drugs are determined as a result of the primary examination, the secondary examination is individually performed for them. Even in that case, it is possible to improve the time efficiency as compared with the case where the secondary examination is always performed for all drugs. However, the user may be allowed to select from a plurality of modes as to under what conditions the secondary inspection is performed. For example, it is also possible to condition the capsule to always apply the secondary inspection.

  In the present embodiment, the primary inspection and the secondary inspection are performed at the same place (inspection station 36) in order to shorten the time required for positioning the probe 40 in the secondary inspection. With such a configuration, it is not necessary to move the medicine package 14 during the primary examination and the secondary examination, and the movement of the medicine 20 can be prevented almost certainly. As a result, the position of the medicine calculated in the primary examination can be used as it is for positioning the probe 40 in the secondary examination, and the probe 40 can be brought close to the medicine 20 quickly.

  Next, operation examples of the audit support apparatus will be described with reference to FIGS. 9, 10, and 11 </ b> A to 11 </ b> D. FIG. 9 is a flowchart showing a flow of inspection by the audit support apparatus, and FIG. 10 is a flowchart showing a flow of primary inspection. Moreover, FIG. 11A-FIG. 11D is an image figure which shows the flow of a test | inspection.

  When inspecting whether a medicine package is configured according to a prescription, first, the inspection head 29 is moved so that the suction pad 46 is positioned directly above the target medicine package 14, and the medicine is used with the suction pad 46. The package 14 is sucked (S10). At this time, the sheet pressing bar 21 is raised as shown in FIG. 11A. Then, the suction pad 46 is moved together with the inspection head 29 while holding the medicine package 14 with the suction pad 46, and the medicine package 14 is transferred to the inspection station 36 (S12). When the medicine package 14 reaches the inspection station 36, as shown in FIG. 11B, the sheet pressing bar 21 is lowered to press the medicine package sheet 12 onto the transport table 10.

  If it will be in this state, this time, the camera unit 32 moves the test | inspection head 29 to the primary test | inspection execution position located right above the test | inspection station 36 (S14). If it will be in that state, a primary inspection will be performed (S16).

  Specifically, the primary inspection is executed according to the following flow. First, silhouette imaging is performed in which the medicine pack 14 is imaged by the camera 33 with the backlight 28 turned on (S30). Thereby, a silhouette image is acquired. The image analysis unit 64 extracts a contour in each image based on the image obtained by the silhouette imaging (S32). Next, the backlight 28 is turned off, and color imaging is performed in which the medicine bag 14 is imaged by the camera 33 while the illumination 34 installed above is turned on (S34). The image analysis unit 64 specifies the color of each medicine 20 based on the image obtained by this color imaging. Of course, the order of silhouette imaging and color imaging may be reversed. Further, the calculation may be performed while imaging.

  If the outline and color of each medicine 20 are specified, the main control unit 68 performs collation between information recognized for each medicine and information managed on the database (S36). As a result, if a match is recognized, the drug name can be specified for each target drug. If the drug names can be specified for all the drugs 20 included in the medicine package 14 to be inspected, in other words, if no collation failure occurs (No in S38), the primary inspection ends.

  On the other hand, if a collation failure drug is generated (Yes in S38), the center coordinates of the drug for which the collation has failed are calculated (S40). The position-calculated drug is primarily stored as a target drug for the secondary examination (S42).

  When the primary examination is completed, the main control unit 68 confirms the presence or absence of the medicine to be subjected to the secondary examination (S18). If there is no medicine to be subjected to the secondary examination, the examination for the medicine package 14 is completed. In this case, the main control unit 68 confirms whether there are other medicine packages 14 to be inspected (S28), and if there are, returns to step S10 and repeats the same procedure again. On the other hand, when the inspection for all the medicine packages 14 is completed, the inspection is terminated.

  In addition, after the primary test is completed, when there is a drug to be subjected to the secondary test (Yes in S18), the distance of the drug to be subjected to the secondary test is subsequently measured (S20, S22). Specifically, as shown in FIG. 11C, the test head 29 is moved so that the distance sensor 48 is positioned directly above the target drug. The movement amount at this time is calculated based on the center coordinates of the medicine calculated in the primary examination. If the distance sensor 48 is positioned immediately above the target drug, the distance sensor 48 is driven to measure the distance to the target drug. The distance information obtained by the measurement is sent to the main control unit 68.

  If the distance can be measured, then the secondary inspection is executed (S24, S26). That is, the inspection head 29 is moved to the secondary inspection execution position where the probe 40 is positioned immediately above the target medicine for the secondary inspection. At this time, as shown in FIG. 11D, not only the horizontal position of the test head but also the height is controlled so that the tip of the probe 40 is brought close to the upper surface of the target drug. For the position control of the probe 40 at this time, the center coordinate value of the medicine calculated in the primary examination and the distance to the medicine obtained by the distance measurement are used.

  If the probe 40 can be brought close to the target drug, the target drug is irradiated with near-infrared light, and a spectrum of diffuse reflected light is generated based on the reflected light obtained at that time. The spectrum analysis unit 66 generates a profile by repeating the differential processing twice for the obtained spectrum and outputs the data to the main control unit 68. The main control unit 68 identifies the drug name of the target drug based on comparison and matching between the obtained profile and the profile stored in the database 70.

  In addition, when there are a plurality of secondary target drugs in one medicine package, the secondary inspection may be performed after measuring the distances of all the target drugs, or the distance of one target drug is measured. A secondary examination of the target drug may be performed whenever possible.

  In any case, if all drug names can be specified by the primary examination and the secondary examination, the drug names are displayed on the display unit 72 as the audit results. The audit result may be displayed on the display unit 72 and stored in the database 70 or printed on paper. In addition, if there is a drug whose drug name cannot be specified even after the primary test and the secondary test, an error is output as an audit result.

  As is clear from the above description, according to the present embodiment, since the medicine package is not moved between the primary examination and the secondary examination, the position of the medicine is unchanged. As a result, the position information calculated in the primary inspection can be used for the secondary inspection as it is, and the time required for the secondary inspection can be greatly shortened. Moreover, in this embodiment, since the secondary examination is performed only about the chemical | medical agent in which the chemical | medical agent name was not able to be specified by the primary examination, the time which the whole examination requires can be reduced significantly.

  In the present embodiment, the medicine pack 14 is transferred by the suction pad 46 that sucks and holds the medicine pack 14. However, a mechanism for sending the medicine pack sheet 12 from the upstream side to the downstream side is provided on the transport table 10 side. May be. For example, the medicine pack sheet 12 may be transported downstream by a transport mechanism including a transport belt on which the medicine pack sheet 12 is placed and a transport roller that sends the transport belt downstream. In such a configuration, the suction pad 46 may be omitted.
