  Patent Document 2 discloses a liquid medicine dispensing device that displays an inspection image. The inspection image is a composite of a plurality of dosing container images corresponding to a plurality of injection processes arranged in a horizontal direction, and represents an increase in the liquid level. An individual liquid medicine prescription amount (injection instruction amount) is numerically displayed adjacent to it, but it may not be easy to intuitively recognize each injection instruction amount on each medication container image.

  An object of the present invention is to enable accurate dispensing inspection. Alternatively, the injection instruction amount and the actual injection amount can be easily compared.

  The liquid medicine dispensing device according to the present invention is based on an injection mechanism that injects a plurality of liquid medicines into a medication container in stages, an imaging means that images the medication container, and an output signal from the imaging means. Monitoring image forming means for forming a monitoring image representing a change in liquid level in the dosing container caused by stepwise injection of liquid medicine, and a plurality of injection instruction amounts for the plurality of liquid medicines A reference image forming means for forming a reference image representing a plurality of prescribed levels to be compared with a liquid level in the medication container; a display means for displaying an inspection image including the monitoring image and the reference image; It is characterized by including.

  According to the above configuration, the reference image is displayed on the screen in addition to the monitoring image. The reference image represents a plurality of defined levels that are compared with the liquid level in the medication container. Desirably, each prescribed level is a liquid level in the dosing container that is assumed in calculation after execution of each liquid medicine injection step, and is obtained, for example, from the total value of the injection instruction amounts so far. By visually comparing the actual liquid level and the specified level after each liquid medicine injection step is completed, it can be easily and intuitively confirmed that the injection according to the calculation, that is, the instruction is proceeding smoothly. If the actual liquid level is deviated from the specified level, the amount of deviation can be recognized as inspection information. For example, the dispensing error may be visually determined or automatically determined based on the deviation amount.

  The monitoring image is preferably configured as a photographed single medication container image or as a composite image of a plurality of photographed medication container images. In that case, the entire captured image frame, that is, the entire medication container image may be used as it is, or a portion of the image frame (for example, a belt-like portion corresponding to the end portion of the medication container image) after trimming. May be used. The medication container image is a still image or a moving image. For example, a prescription container image as a still image is acquired after completion of each liquid medicine injection process, or a prescription container image as a moving image is acquired during the progress of each liquid medicine injection process. A moving image may be displayed during execution of liquid medicine injection, and a still image may be displayed from the completion of liquid medicine injection. Note that the liquid level in the medication container may be detected, and a graphic image showing the liquid level may be formed based on the detected liquid level. Such an image can also be used as a monitoring image.

  Since the reference image is an image representing a plurality of defined levels compared to the liquid level in the medication container, it is preferably configured as a graphic image. If the prescribed level is displayed on the displayed prescription container image in a superposed manner or at a position adjacent to it, it becomes easy to compare the prescribed level with the actual liquid level. The reference image is preferably composed of one or a plurality of graphs, and each graph has one or a plurality of sections arranged in the vertical direction. In that case, each section corresponds to the liquid level change width that occurs when each dispensing instruction amount is placed in the medication container. Note that only one specified level may be displayed, or it may be displaced (increased) step by step.

  Preferably, the reference image forming unit determines the plurality of prescribed levels based on a plurality of injection instruction amounts and injection orders for the plurality of liquid medicines. Preferably, the reference image forming unit further determines the plurality of specified levels based on a type of the medication container. Since the liquid level in the dosing container depends on the type of the dosing container, that is, the internal volume and the internal shape, it is desirable to calculate the height of each prescribed level in consideration of the type of the dosing container.

  Preferably, the reference image includes a plurality of sections arranged in a vertical direction representing the plurality of injection instruction amounts, and upper sides of the plurality of sections represent the plurality of specified levels. Preferably, the plurality of sections are colored with a plurality of hues. If the hues are different, it is easy to identify individual sections. Preferably, the display means displays a liquid medicine list in which a plurality of liquid medicine names are described together with the inspection image, and the liquid medicine list represents a plurality of hues associated with the plurality of liquid medicines. A hue correspondence table is included. According to this configuration, it is possible to easily specify the prescribed level for a specific liquid medicine in the liquid medicine list.

  The liquid medicine dispensing device according to the present invention is based on an injection mechanism that injects a plurality of liquid medicines into a medication container in stages, an imaging means that images the medication container, and an output signal from the imaging means. Monitoring image forming means for forming a monitoring image composed of a plurality of medication container images representing a change in the liquid level in the medication container caused by the stepwise injection of a liquid medicine; and a plurality of the plurality of liquid medicines A reference image forming means for forming a reference image consisting of a plurality of graphs representing a plurality of prescribed levels to be compared with the liquid level in the dosing container based on the injection instruction amount of the monitoring container, the monitoring image, and the reference image Display means for displaying an inspection image including According to the above configuration, the monitoring image is configured by a plurality of medication container images. On the other hand, the reference image is composed of a plurality of graphs. If a graph is displayed for each prescription container image, inspection of each liquid medicine injection process can be performed more accurately. Each graph is, for example, a color bar graph.

  Preferably, the monitoring image is composed of medication container images from No. 1 to No. n corresponding to No. 1 to n (where n is an integer greater than or equal to 2) No. 1, and the reference image is It consists of graphs from No. 1 to No. n corresponding to the No. 1 to No. n liquid medicine injection processes, and the plurality of specified levels are No. 1 corresponding to the No. 1 to No. n liquid medicine injection processes. To the nth, and the i-th graph is displayed adjacent to or superimposed on the i (where i = 1, 2,..., N) -th dosing container image, At least one marker representing at least the i th defined level. The above n is generally the number of liquid medicines prescribed in a specific prescription, or the number of excipients (liquids having no medicinal effect for adjusting the liquid amount) added thereto. In addition, when dispensing a single liquid medicine, the above liquid medicine dispensing apparatus can be used.

  According to the liquid medicine dispensing apparatus according to the present invention, dispensing inspection can be performed accurately. Alternatively, the injection instruction amount and the actual injection amount can be easily compared.

  FIG. 2 shows a function of the liquid medicine dispensing device shown in FIG. 1 as a block diagram. The control unit 48 performs operation control and image processing of each component. The control unit 48 controls the three dispensing units 12, 14, and 16 described above. Specifically, the valves and rotation mechanisms provided in the dispensing units 12, 14, and 16 are controlled. As described above, the imaging unit 24 includes the camera 44 and the light source 46, and an output signal of the camera 44 is sent to the control unit 48. The control unit 48 controls the light source 46. Information such as prescription data from the host system is given to the control unit 48. Based on such data, the control unit 48 calculates and sets a dispensing amount in each dispensing step, that is, a dispensing instruction amount. The control unit 48 controls the transport mechanism 18 and controls the operation of each dispensing unit 12, 14, 16 while controlling the transport mechanism 18 when performing a plurality of dispensing processes. The touch panel 28 includes a display device 50 and an input device 52, and can perform user input by touching a predetermined button with a fingertip on a displayed screen.

  The control unit 48 has an image forming unit 54, which forms a display image, particularly an inspection image described in detail below. Specifically, the image forming unit 54 includes a monitoring image forming unit 56 and a reference image forming unit 58. Each function is described in detail below. Incidentally, the image forming unit 54 is realized by a software function.

  FIG. 3 shows a display example displayed on the screen 60. The display image includes an inspection image 64, a drug list 62, various data 66, and an input button group 68. The inspection image 64 is an image obtained by synthesizing the monitoring image and the reference image as described below. The medicine list 62 is a list describing a plurality of liquid medicine names to be dispensed in a plurality of dispensing steps executed based on a specific prescription.

  FIG. 4 shows the medicine list 62 shown in FIG. 3 alone. Reference numeral 70 indicates a medicine number, that is, a dispensing order. Reference numeral 72 indicates a drug name. Reference numeral 74 indicates a dispensing instruction amount. Reference numeral 76 denotes a color sample table, which is a sample of hues associated with each medicine, that is, each liquid medicine. A different hue is assigned to each liquid medicine. Reference numeral 78 indicates the total amount of liquid medicine to be injected into the medication bottle.

  FIG. 5 shows the inspection image 64 shown in FIG. 3 alone. This inspection image 64 is composed of a monitoring image 80 and a reference image 82. The monitoring image 80 is composed of a plurality of bottle images (medication container images) 84. For example, six bottle images 84 corresponding to six dispensing steps are acquired, and a monitoring image 80 is generated by connecting them in the horizontal direction.

  The reference image 82 assists in observing the liquid level in the monitoring image 80. In the present embodiment, the reference image 82 includes a plurality of reference images 82 formed based on the bottle type, the dispensing instruction amount, and the dispensing order. Bar graph 86. Individual bar graphs 86 constitute graphic image elements. In the present embodiment, six bar graphs 86 are formed corresponding to the six bottle images 84. Each bar graph 86 shows the liquid medicine instruction amount injected in each dispensing step and the total amount so far. Each bar graph 86 is displayed superimposed on or adjacent to each bottle image 84. By referring to each bar graph 86, it is possible to easily recognize the prescribed level of the liquid level in each dispensing step, and whether or not dispensing has been performed correctly based on a comparison between the actual liquid level and the prescribed level. It is possible to accurately determine whether or not.

  Incidentally, reference numeral 90 indicates the number of the dispensing process, which is also an identifier of the bottle image 84 at the same time. The line row 88 is composed of a plurality of horizontal lines 88a, and these horizontal lines 88a represent the amount of liquid. Reference numeral 92 indicates character information representing the liquid amount. In the figure, a horizontal line 88a is drawn every 20 ml. Each horizontal line 88a coincides with the scale formed on the medication bottle in the present embodiment, that is, when the type of the medication bottle is specified, a horizontal line row 88 adapted to it is automatically generated. Reference numeral 96 indicates a dispensing amount, that is, a dispensing instruction amount in each dispensing step. The code | symbol 98 has shown the dispensing total amount calculated in each dispensing process. That is, it is cumulative.

  FIG. 6 schematically shows the trimming process. Reference numeral 100 indicates a bottle image (dose container image) before processing, and reference numeral 106 indicates a bottle image after processing. As shown in the drawing, in the bottle image 100 before processing, one side portion including the scale 102 is specified, and that portion is cut out as indicated by a line 104. The clipped result is an image denoted by reference numeral 106.

  As shown in FIG. 7, the monitoring image 80 can be configured by arranging the bottle images obtained after the respective dispensing steps in order in the horizontal direction and combining them. In this case, in the illustrated example, the monitoring image is composed of five bottle images 84A, 84B, 84C, 84D, and 84E. Among them, the leading bottle image 84A shows an empty state. Such a bottle image 84A is added as necessary. In synthesizing a plurality of bottle images, it is desirable to match the scales of the bottle images, and it is desirable to align the lower end levels of the bottle images. Such a combination process of a plurality of bottle images is disclosed in Patent Document 2.

  FIG. 8 shows the composition processing of the inspection image. The inspection image 64 is composed of the monitoring image 80 and the reference image 82 as described above. The monitoring image 80 is obtained by connecting a plurality of bottle images 84 in a horizontal direction. Specifically, in this example, a gap 107 is generated on the left side of the actual bottle portion in each bottle image 84. In this embodiment, the reference image 82 includes a plurality of bar graphs 86A, 86B, 86C, 86D, 86E, and 86F. That is, it is composed of the same number of bar graphs as the number of dispensing steps. The lower end levels 112 of the bar graphs 86A to 86F are aligned with each other, and the upper end levels thereof are also aligned with each other. That is, the vertical scales of the bar graphs 86A to 86F are the same. Each bar graph 86A to 86F has one or a plurality of cells. Each cell 108a, 108b, 108c, 108d, 108e, 108f represents the dispensing instruction amount (specified amount) in the 1st to nth liquid medicine dispensing, in other words, the liquid in each dispensing process. It represents the fluctuation range of the surface. In the present embodiment, different hues are assigned to the respective liquid medicines, and the cells 108a to 108f are colored by the hues assigned to the respective liquid medicines. In the case where there are dispensing processes from No. 1 to n, and i = 1, 2,..., N, the bar graph corresponding to the i-th dispensing process is the number of i graphs executed so far. Reflects the result of the dispensing process, i.e. has i cells. Therefore, the first bar graph 86A has one cell corresponding to the first dispensing process, and the last nth bar graph 86f has n cells corresponding to all dispensing processes, that is, n dispensing processes. In the illustrated example, six cells 108a to 108f are provided. The upper side of each cell represents the specified level compared with the actual liquid level.

  That is, in the inspection image 64, a bottle image captured after completion of each dispensing process is displayed, and a bar graph is displayed on the left side of the bottle image. The bar graph includes one or a plurality of cells corresponding to the dispensing process executed so far, and the upper side of the top cell represents the total dispensing amount (specified level) so far. By comparing with the actual liquid level, it is possible to visually determine whether the previous dispensing process has been performed properly, that is, whether the dispensing results are appropriate.

  In the above embodiment, a bar graph, that is, a graphic element extending in the vertical direction is used as an element of the reference image. However, it is also possible to display a specified level simply by a horizontal line. For example, in the display example shown in FIG. 3, the memory line row is displayed, but instead, a memory line row representing a plurality of specified levels may be displayed. In any case, it is desirable to display an auxiliary image so that the specified level and the actual liquid level can be compared after completion of each dispensing process or during execution of the dispensing process.

  In the above embodiment, a unique hue is assigned to each liquid medicine, and each cell is colored with a unique hue corresponding to each liquid medicine when displaying the bar graph. The advantage is that it is possible to prevent liquid medicines from being mixed up. As a result, it is possible to correctly understand the correspondence between the inspection image and the medicine list, and it is possible to obtain an advantage of preventing the misidentification of the medicine.

  The setting or calculation of the specified level can be performed using the method shown in FIG. From the type of medication bottle, the relationship between the internal volume of the medication bottle and the liquid level is known, and for example, the height on the screen from 0 mL indicated by reference numeral 116 to 20 mL indicated by reference numeral 114 is automatically recognized. can do. On the screen, for example, when there are 40 pixels as indicated by reference numeral 118, it is possible to calculate the liquid amount per pixel as indicated by reference numeral 120. Here, the interval between two lines corresponds to 20 mL, which corresponds to the number of 40 pixels, so that 0.5 mL per pixel can be obtained. However, the shape of the lower part of the medication bottle may not be straight, and in this case, the correct liquid level cannot be calculated by simple calculation. It is possible to specify the relationship with the surface level in advance, and it is possible to automatically calculate the height of the specified level corresponding to the total amount dispensed, that is, the height on the screen, from such relationship It is.

  FIG. 10 shows another display example. A display screen is displayed on the screen 60, which includes an inspection image 124 and a medicine list 122.

  FIG. 11 shows a medicine list 122, in which reference numeral 126 indicates the number of the dispensing process, reference numeral 128 indicates the drug name, reference numeral 130 indicates the amount dispensed, Reference numeral 132 denotes a color sample list. In the medicine list 122, a line corresponding to the currently executed dispensing process is identified and displayed as indicated by reference numeral 136. The lines corresponding to the previous one or more dispensing processes are displayed in the normal manner as indicated by reference numeral 134, and the one or more lines corresponding to the dispensing process to be executed from now on are indicated by reference numeral 138. Expressed by halftone. That is, it is possible to easily recognize the contents of the dispensing process currently being executed by such an expression form.

  FIG. 12 shows the inspection image 124 shown in FIG. The inspection image 124 includes a monitoring image 140 and a reference image 142, and the monitoring image 140 is configured as a single bottle image. The reference image 142 is composed of a single bar graph 144. Incidentally, reference numeral 146 indicates a horizontal line row.

  The monitoring image 140 is configured as a moving image, that is, the dispensing process is imaged in real time, and the imaging result is displayed as a moving image. On the other hand, the bar graph 144 is configured by a plurality of cells corresponding to a plurality of dispensing steps as described above, and specifically, these cells are stacked from the bottom to the top. Each cell represents a dispensing instruction amount in each dispensing process, and specifically shows a change range of the liquid level expected in each dispensing process. Each cell, that is, the upper side of each section represents a specified level, and it is possible to confirm whether dispensing has been performed properly by comparing the liquid level that fluctuates in the bottle image with each specified level. it can. Also, if the liquid level is displayed as a moving image, it is possible to intuitively understand how much dispensing will be performed during the dispensing process. Also in the inspection image 124, for example, a specific cell may be highlighted on the bar graph 144 so that the current dispensing process can be specified.

  Incidentally, the bottle image may be frozen at the stage where each dispensing process is completed, that is, the moving image may be switched to the still image. For example, also in the embodiment shown in FIG. 3, individual bottle images can be displayed as moving images.

  When capturing a moving image, for example, a configuration as shown in FIG. 13 can be employed. In FIG. 13, the movable body 148 includes a medication bottle 22, which has a holder 144 and a camera 150. The holder 144 is provided on the base 42 and holds the prescription bottle 22 in a detachable manner. The camera 150 is attached to the support member 152 and images the bottle 22 from the side of the bottle 22. In this example, a light source may be provided on the camera 150 side. Since the camera 150 is provided at a position relatively close to the medication bottle 22 and imaging is performed there, the obtained image may be corrected so as to be a parallel projection image. Alternatively, parallel projection may be performed using an optical system. According to the above configuration, it is possible to observe the generation of bubbles and the mixing of foreign matters at the time of dispensing as an image. Incidentally, it is desirable to perform color imaging when imaging. That is, it is desirable to provide the user with the color of the liquid medicine.

  In forming the reference image shown in FIGS. 3 and 10, the type of bottle is referred to. The type of bottle may be automatically determined or manually input by the user. Moreover, you may make it discriminate | determine automatically from the content of a prescription. In forming the reference image, the dispensing instruction amount (prescription amount) and the dispensing order in each dispensing step are considered. Since the liquid level changes from the bottom to the top in the progress of each dispensing process, it is desirable that a plurality of specified levels are displayed corresponding to the liquid level.
