Description

[Technical Field]

[0001] The present invention relates to a pharmaceutical work management system. [Background technology]

[0002] In product manufacturing sites, especially pharmaceutical manufacturing sites, workers must strictly adhere to the work content that is defined for each work procedure, but deviations such as skipping a work procedure or making mistakes in the work content may occur due to some factors.The causes of such deviations can be confirmed after the work by recording the screen image data at the time of the deviation along with the system log, but if the screen image data is tampered with, it will be impossible to accurately understand the situation at the time the deviation occurred.

[0003] Patent Document 1 discloses a work procedure management system that detects tampering with screen image data when deviations from work procedures occur during pharmaceutical manufacturing. Specifically, it discloses that the system records processing log information and screen hard copies along with a session ID assigned when logging in to the server, and when a deviation is determined, records the details of the deviation and information obtained by encoding part of the screen hard copy.

[0005] However, although Patent Document 1 can detect tampering with screen image data and determine deviations from work after the work has been completed, it does not take into consideration preventing deviations from work in advance.

[0006] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a pharmaceutical work management system that can prevent deviations from work. [Means for solving the problem]

[0010] Hereinafter, an embodiment of the pharmaceutical work management system according to the present invention will be described with reference to the accompanying drawings. In the following description and accompanying drawings, components having the same functional configuration are designated by the same reference numerals, and redundant explanations will be omitted. [Example]

[0011] FIG. 1 shows the overall configuration of a pharmaceutical work management system 100. The pharmaceutical work management system 100 is a system for managing work on pharmaceuticals, and includes a pharmaceutical work management device 101 and a camera 109. The pharmaceutical work management device 101 is configured by connecting a calculation unit 102, a memory 103, a storage unit 104, and an interface 105 via a system bus 106 so that signals can be transmitted and received. Here, "signals can be transmitted and received" refers to a state in which signals can be transmitted and received between each other or from one device to the other, whether electrically or optically, wired or wirelessly. A display device 107 and an input device 108 may be connected to the pharmaceutical work management device 101.

[0012] The calculation unit 102 is a device that controls the operation of each component, and is specifically a CPU (Central Processing Unit), MPU (Micro Processor Unit), etc. The calculation unit 102 loads programs stored in the storage unit 104 and data required for program execution into the memory 103 and executes them. The memory 103 stores programs executed by the calculation unit 102 and intermediate progress of calculation processing. The storage unit 104 is a device that stores programs executed by the calculation unit 102 and data required for program execution, and is specifically a HDD (Hard Disk Drive), SSD (Solid State Drive), etc. The interface 105 is for connecting the medical work management device 101 to the camera 109.

[0013] The display device 107 is a device that displays the processing results of the medical work management device 101, and is specifically a liquid crystal display, etc. The input device 108 is an operation device with which the operator issues operation instructions to the medical work management device 101, and is specifically a keyboard, mouse, touch panel, etc. The mouse may be another pointing device such as a trackpad or trackball.

[0014] The camera 109 is a device that captures images of work performed by a worker on a workbench using a work tool on pharmaceuticals. The captured images are still images or videos, and are stored in the memory unit 104 via the interface 105.

[0015] The work content for pharmaceuticals is strictly defined for each work procedure, and workers are required not to deviate from the defined work content. Therefore, in Example 1, based on the result of comparing a model image, which is an image of the defined work content taken in advance for each work procedure, with an actual work image, which is an image of the actual work performed by the worker, it is determined whether or not there is a deviation in the work, and if there is a deviation, a warning is given to the worker.

[0016] An example of the flow of processing for capturing a sample image will be described step by step with reference to FIG.

[0017] (S201) The calculation unit 102 acquires the work procedure manual. The work procedure manual indicates the work content for each work as shown in FIG.

[0018] (S202) The calculation unit 102 reads out the work content for each work from the work procedure manual acquired in S201. For example, the work content for dilution work is read out from the work procedure manual of Fig. 3. The dilution work is a work performed on a specimen sampled from, for example, received raw materials.

[0019] Using Figure 4, the details of the dilution work for work numbers 001-1 to 001-3 in the work procedure manual of Figure 3 will be explained. First, a fixed amount of sample is transferred from a 100 mL flask containing a sampled specimen to a 50 mL flask α using a 10 mL pipette. Since the amount of sample transferred to 50 mL flask α is 30 mL, the 10 mL pipette is used three times. Next, a fixed amount of diluent is poured into the 50 mL flask α to which 30 mL of sample has been transferred using a 20 mL pipette. Since the amount of diluent poured into 50 mL flask α is 20 mL, the 20 mL pipette is used once. This completes work number 001-1. Next, as the dilution work for work number 001-2, 30 mL of sample and 20 mL of diluent are poured into 50 mL flask β, and as the dilution work for work number 001-3, 30 mL of sample and 20 mL of diluent are poured into 50 mL flask γ.

[0020] (S203) The calculation unit 102 causes the camera 109 to capture the work content read out in S202 for each work procedure. For example, the work content of the dilution work for work number 001-1 in the work procedure manual of FIG. 3 is captured by the camera 109 for each work procedure.

[0021] Using Figure 5, the procedure for the dilution operation for operation number 001-1 will be explained. First, the procedure for transferring 30 mL of sample from a 100 mL flask to 50 mL flask α using a 10 mL pipette will be explained. In operation procedure (A), the 10 mL pipette approaches the 100 mL flask containing the sampled sample. In operation procedure (B), the 10 mL pipette aspirates 10 mL of sample from the 100 mL flask. In operation procedure (C), the 10 mL pipette that has aspirated the sample approaches 50 mL flask α. In operation procedure (D), the 10 mL pipette dispenses 10 mL of sample into 50 mL flask α. By repeating the above operation procedures (A) to (D) three times, 30 mL of sample is transferred to 50 mL flask α.

[0022] Next, we will explain the procedure for adding a fixed amount of diluent using a 20mL pipette to 50mL flask α, which has already contained 30mL of sample. In procedure (E), the 20mL pipette that has aspirated the diluent approaches 50mL flask α. In procedure (F), the 20mL pipette dispenses 20mL of diluent into 50mL flask α.

[0023] After the work procedures (A) to (D) are repeated three times, the work procedures (E) and (F) are performed, thereby completing the dilution work for work number 001-1. The camera 109 captures each of the work procedures (A) to (F) as a sample image for each work procedure of the dilution work for work number 001-1.

[0024] (S204) The calculation unit 102 associates the model image acquired by photographing in S203 with the work procedure and stores it in the storage unit 104. For example, a model image of a 10 mL pipette approaching a 100 mL flask is stored in association with work procedure (A) with work number 001-1.

[0025] (S205) The calculation unit 102 determines whether there is a next task. If there is a next task, the process returns to S202, and if there is not, the process flow ends.

[0026] A model image is stored in association with each work procedure of a predetermined work content according to the processing flow described using Fig. 2. The model image associated with each work procedure in the work procedure manual is used to determine whether the actual work performed by the worker deviates from the predetermined work content.

[0027] An example of the flow of processing for determining deviations in work will be described step by step with reference to FIG.

[0028] (S601) The calculation unit 102 acquires the work procedure manual. In the work procedure manual acquired in S601, a model image is associated with each work procedure of a predetermined work content.

[0029] (S602) The calculation unit 102 reads out the work procedure and the model image from the work procedure manual acquired in S601. The read-out model image may be displayed on the display device 107 so that the worker can refer to it for the work.

[0030] (S603) The camera 109 captures images of actual work performed by workers. The captured images of actual work are stored in the storage unit 104 for each work procedure. Storing the images of actual work for each work procedure allows the images of actual work to be searched for using the work number and work procedure as keys, thereby reducing the amount of work required to investigate the work content. The actual work images stored for each work procedure may also be associated with the time of work and the name of the worker. Associating the actual work images for each work procedure with the time of work and the name of the worker reduces the effort required to interview workers about the work content.

[0031] (S604) The calculation unit 102 determines whether or not there is a deviation in the work based on the result of comparing the model image read out in S602 with the actual work image captured in S603. If there is a deviation, the process returns to S603 via S605, and if there is no deviation, the process proceeds to S606.

[0032] The presence or absence of deviation in work is determined, for example, based on the amount of deviation between the position of the work tool extracted from the model image and the actual work image. That is, if the amount of deviation between the position of the work tool in the model image and the position of the work tool in the actual work image is equal to or greater than a predetermined threshold, it is determined that there is a deviation. Note that the work tools in the model image and the actual work image are extracted based on, for example, a two-dimensional barcode or color previously attached to the work tool. The work tools may also be extracted based on the shape of the work tool or text attached to the work tool.

[0033] Furthermore, if the work involves dilution, deviations in the work may be determined based on the distance between the pipette and flask used as work tools. For example, the distance between the 10 mL pipette and the 100 mL flask extracted from the model image of work procedure (A) and the actual work image is compared, and if the difference in distance between the two images is greater than or equal to a threshold, a deviation is determined. Note that if a 20 mL pipette is extracted from the actual work image of work procedure (A) instead of the 10 mL pipette, the distance between the 10 mL pipette and the 100 mL flask cannot be determined in the actual work image, and the distance between the two images cannot be compared, so a deviation is determined.

[0034] Furthermore, since the dilution process requires a certain amount of time to aspirate and dispense the sample, the presence or absence of deviations in the process may be determined based on the approach time, which is the time it takes for the pipette and flask to approach each other. For example, the approach times calculated from the model image and the actual work image of the work procedure (B) are compared, and if the difference in approach time between the two images is equal to or greater than a threshold, it is determined that a deviation has occurred. Note that whether the pipette and flask are close to each other is determined based on the distance between the pipette and flask extracted from the model image and the actual work image. In other words, if the distance between the pipette and flask is equal to or less than a threshold, it is determined that the pipette and flask are close to each other.

[0035] (S605) The calculation unit 102 displays an alert on the display device 107 to indicate that a deviation has occurred in the work. The alert display may be text indicating that a deviation has occurred, or the entire screen or part of it may blink or change color. By displaying the alert, the worker becomes aware of the deviation and can redo the work. In other words, deviations in the work can be prevented before they occur.

[0036] (S606) The calculation unit 102 determines whether or not there is a next work procedure. If there is a next work procedure, the process returns to S602, and if there is not, the process flow ends.

[0037] The process flow explained using Figure 6 makes it possible to determine whether or not there has been a deviation in the actual work performed by the worker. If there is a deviation, an alert is immediately displayed, making it possible to prevent deviations in work before they occur.
