Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. The following embodiments do not limit the invention according to the claims. Although a plurality of features are described in the embodiment, not all of the plurality of features are essential to the invention, and the plurality of features may be arbitrarily combined. Further, in the attached drawings, the same or similar configurations are designated by the same reference numbers, and duplicate description is omitted.

<First Embodiment>
FIG. 1 shows a sterilization workflow for a sterilization process according to this embodiment. In this embodiment, the sterilization workflow means a series of steps performed on a sterilization process on a sterilized object. The assembly process is the process of grouping one or more objects to be sterilized at the sterilization station. In addition, there may be one sterilization object included in one group. Grouping is performed, for example, based on the correspondence between the surgery in which the sterilized object is used and the sterilization processing device used for the sterilization process of the sterilized object. For example, sterilized objects used in the same surgery and sterilized by the same sterilizer can be grouped into the same group. The packaging step is a step of packaging one or more objects to be sterilized in one group and CI (first indicator) with one packaging member to form one set at the sterilization station. Usually, in hospitals and the like, a plurality of sterilization objects of the same type are used, and thus a plurality of sets containing the same sterilization object can be formed. Hereinafter, a plurality of sets containing the same sterilized object will be referred to as the same type of set. Conversely, different types of two sets mean that at least one of the sterilized objects contained in the two sets is different. The type of CI packaged in the set in the packaging process is determined according to the combination of the sterilized object in the set and the sterilization processing device that performs the sterilization process of the set. The sterilization step is a step of sterilizing the packaged set with a sterilization processing device.

The storage step is a step of moving the set that has been sterilized in the sterilization step to a storage and storing it. The payout process is a process of moving a set used in surgery or the like from a storage to a place of use such as an operating room. The opening process is a process of opening the packaging of the set that has been moved to the place of use. The surgical process is also a utilization process that utilizes a sterilized object. The achievement level of the sterilization process is determined by using the CI enclosed in the set before using the sterilized object in the opening step, the surgical step, or both. Then, the sterilized object is actually used only when it can be determined by CI that the sterilization process has been sufficiently achieved. The recovery step is a step of moving the sterilized object to the sterilization station after using the sterilized object. The cleaning step is a step of cleaning the object to be sterilized at the sterilization station. After cleaning the set in the cleaning process, the set is sent to the assembly process.

FIG. 2 is a configuration diagram of a management system 100 that manages the sterilization workflow. A server device 14, a plurality of personal computers (hereinafter, PCs) 15, and a sterilization processing device 13 are connected to the network. The server device 14, the PC 15, and the sterilization processing device 13 can communicate with each other via a network. The server device 14 manages management information (sterilization record information) related to the sterilization workflow. The PC 15 can add or modify information to the management information held by the server device 14 via the network. Further, the PC 15 and the server device 14 can present various information to the user of the management system 100 based on the management information held by the server device 14. The presentation of various information includes, for example, displaying the presented content on the display of the PC 15, outputting the presented content to a printer connected to the PC 15, and outputting information indicating the presented content to a PC used by the user (not shown). It is done by any method. As described above, there are various methods for presenting / displaying various information to the user, but in the following, these are collectively referred to as "the management system 100 presents / displays (information to the user)". In the present invention, the user means a person related to the sterilization workflow, such as a worker who actually works in each step of the sterilization workflow and a supervisor who supervises the worker.

The PC 15 is installed in a place where it is necessary to refer to the management information, add information to the management information, or modify the management information in the sterilization workflow. Further, as shown in FIG. 1, a part of the PC 15 is connected to the measuring device 1. The measuring device 1 is a device that measures a discolored region of CI. In the present embodiment, the measuring device 1 is configured to be able to function as a reading device for reading the identification information of the CI in addition to measuring the discolored region of the CI. Therefore, the measuring device 1 is installed not only in the place where the CI needs to be measured but also in the place where the CI identification information needs to be read, and is connected to the PC 15 installed in the same place. The network of FIG. 1 is not limited to the network closed in the hospital. For example, the sterilization station may be outside the hospital, in which case the network will connect the hospital with the sterilization station outside the hospital. Further, the network may be a closed network such as a local area network (LAN) that does not connect to another network, or may include a LAN and the Internet. For example, the network can be configured by the Internet and a LAN in the hospital connected to the Internet. In this case, the management system 100 is configured by installing the server device 14 outside the hospital and connecting to the Internet. can do.

Further, in the present embodiment, the sterilization processing device 13 is connected to the network, and the PC 15 and the server device 14 acquire information to be added to the management information and information for correcting the management information from the sterilization processing device 13. be able to. However, the sterilization processing apparatus 13 may be configured not to be connected to the network. In this case, the operator operates the PC 15 based on the information output by the sterilization processing apparatus 13, and adds / corrects the management information. In addition, in order for the worker to input / update / display the management information, it is necessary to operate the PC15, etc., but in the following, for the sake of simplification of the explanation, the description of operating the PC15 is omitted. .. For example, the fact that the worker operates the PC 15 to input information into the management system 100 is also expressed as the worker inputting information into the management system 100.

In the present embodiment, identification information is assigned to each set. The identification information can be, for example, in the form of a serial number or barcode printed on a sticker. Alternatively, the identification information can be recorded on the IC tag. The medium having the identification information is attached to, for example, the outer surface of the packaging member of the set or the sterilized object of the set. Alternatively, it can be attached to the CI enclosed in the set. When the serial number or the like is recorded in the CI itself, the serial number of the CI enclosed in the set can be used as the identification information of the set. In the present embodiment, the CI serial number enclosed in the set is used as the identification information of the set.

FIG. 3 shows the CI according to the present embodiment. The CI is a sheet-shaped test paper, and has a discolored region 21 whose surface is chemically treated. The color of the discolored region 21 changes according to the degree of achievement of the sterilization process. In the present embodiment, the discolored region 21 of the CI has a color value C # 1 in the initial state, changes to a color value C # 2 to a color value C # 9 according to the degree of achievement of the sterilization process, and finally. Is configured to be constant at the color value C # 10. Hereinafter, the degree of achievement of the sterilization process when the color value C # k (k is an integer from 1 to 10) is defined as the degree of achievement #k. The color change region 21 does not become any of the color values C # 1 to C value # 10, but continuously changes from the color value C # 1 to the color value C # 10. That is, the color change region 21 can also take a color between the color value C # m (m is an integer from 1 to 9) and the color value C # m + 1. In this embodiment, the level of achievement of the sterilization process is evaluated on a 9-point scale. Specifically, when the color of the discolored region 21 is within the range of the color value C # m to the color value C # m + 1, the level of the sterilization process is determined to be the level # m. Then, for example, levels # 4 to # 9 are set to OK levels, and levels # 1 to # 3 are set to NG levels. Here, the level # m of the sterilization treatment means that the achievement level of the sterilization treatment is within the range of achievement degree # m to achievement degree # m + 1.

Further, the CI has an identification unit 22 having identification information. In FIG. 3, the identification unit 22 prints the serial number of the CI on the ground below the CI. As described above, the identification unit 22 may have a barcode printed on it or an IC tag (wireless tag) attached to the CI.

FIG. 4 is a cross-sectional view of the measuring device 1 according to the embodiment. Reference numeral 2 in FIG. 4 indicates the CI conveyed to the measurement position of the measuring device 1, and the dotted line indicates the CI before being inserted into the measuring device 1. The CI inserted into the insertion portion 4 of the measuring device 1 is conveyed to the measurement position by the transfer roller pair 6. The measuring unit 3 measures the color of the discolored region 21 of the CI. After the CI is measured, the transfer roller pair 6 is rotated in the reverse direction, so that the CI is discharged to the outside of the measuring device 1. The measuring unit 3 reads the optical measured value related to the color value of the discolored region 21 of the CI, for example, the spectral reflectance by the light 7. In the present embodiment, the measuring unit 3 is configured to read the identification information of the CI in addition to the color value of the discolored region 21 of the CI. When the identification unit 22 is a serial number or a barcode, the measurement unit 3 can optically read the identification unit 22 of the CI. If the identification unit 22 is an IC tag, the measurement unit 3 has an IC reader and communicates with the IC tag to read the identification information stored in the IC tag. Further, the measurement unit 3 can be configured to read the color value and the identification information of the color change region 21 by imaging the color change region 21 and the identification unit 22 with the image sensor. The control unit 8 controls the measuring device 1. Various information used for measurement is stored in the storage unit 9 of the control unit 8. Further, the arithmetic processing unit 10 of the control unit 8 determines the color value of the color change region 21 of the CI based on the measurement result by the measurement unit 3, for example, the spectral reflectance. The control unit 8 outputs the color information indicating the determined color value and the read CI identification information to the PC 15.

The measuring device 1 shown in FIG. 4 discharges the CI from the insertion unit 4, but as shown in FIG. 5, the discharging unit is discharged on the side opposite to the insertion unit 4 with respect to the measurement position of the CI. The configuration may be such that the CI is discharged from the discharge unit after being provided and measured. Further, the measuring device 1 shown in FIG. 4 measures the CI by the fixed measuring unit 3 after transporting the CI to the measuring position, but as shown in FIG. 6, the measuring unit 3 can be moved. It can be configured as follows. That is, the measuring unit 3 may be moved in a predetermined direction to read the discolored region 21 and the identification unit 22 of the CI. Further, as shown in FIG. 7, the operator may move the measuring device 1 on the CI to read the discolored region 21 and the identification unit 22 of the CI. Such a configuration is advantageous when utilizing CIs of various sizes.

When the CI identification information is not used as the identification information of the set, the identification information is read according to the medium on which the identification information is recorded and the format of the identification information and output to the PC 15. For example, if the identification information is a barcode, a barcode reader can be used to read the identification information. Further, when the identification information is a serial number, the operator may input the identification information into the management system 100.

FIG. 8 shows the inside of the sterilization processing apparatus 13. In the present embodiment, a plurality of sub-regions are defined by dividing the arrangement region in which the set is arranged in the sterilization processing apparatus 13. In the following description, each sub-region is expressed as a zone. In FIG. 8, the arrangement area of the set is divided into two in each of the vertical direction and the horizontal direction, and four zones A to D are defined. It should be noted that how to divide the arrangement area of the sterilization processing apparatus 13 is arbitrary, and the number of zones is not limited to four. For example, the arrangement area can be further divided in the front-rear direction. In addition, in order to make the boundary of the zone in the sterilization processing device 13 visible to the operator, a partition indicating the boundary of the zone may be provided in the sterilization processing device 13, or a mark may be provided with tape or the like.

FIG. 9 shows a management information table (sterilization record table) which is management information held by the server device 14 in the present embodiment. The number field indicates the number of each record. The identification information field of the record stores the identification information of the set. In the present embodiment, the identification information of the set is the identification information of the CI enclosed in the set. Each record records sterilization-related information related to the sterilization process for the set of identification information stored in the identification information field. The sterilization-related information will be described below. First, the set field stores information that identifies the type of corresponding set. The sterilizer field stores information that identifies the sterilizer 13 that sterilizes the set. The worker field stores information that identifies the worker performing the sterilization process for the set. The sterilization date and time field stores information indicating the date and time when the set was sterilized. The result information field has two subfields, pre-sterilization and post-sterilization. In the present embodiment, the discolored region 21 of the CI is measured by the measuring device 1 before the CI is enclosed in the set, and it is determined whether or not the CI has an initial defect based on the measurement result. Then, the determination result is stored in the pre-sterilization subfield. Further, after the sterilization treatment of the set, the discolored region 21 of the CI enclosed in the set is measured by the measuring device 1, and the level of achievement of the sterilization treatment is determined based on the measurement result. Then, the determined achievement level is stored in the subfield after sterilization. When the set is sterilized, the arrangement position field stores information indicating a zone in the sterilization apparatus 13 in which the set is arranged.

For example, in the packaging process, a CI whose identification information shown in FIG. 3 is 12345678 is enclosed. The operator operates the PC 15 to add a new record (number 101 in FIG. 9) to the management information table as a record to be recorded. Then, the worker inputs into the management system 100 information for specifying the type of the target set of the packaging process, information for specifying the sterilization processing device to be used, and information for specifying the worker. As a result, this information is recorded in the set field, the sterilizer field, and the worker field of the record to be recorded. The operator causes the measuring device 1 to read the CI whose enclosed identification information is 12345678. As a result, the measuring device 1 outputs the color value (hereinafter, measured color value) Ct of the discolored region 21 and the identification information to the PC 15 as the measurement result. After confirming that the record corresponding to the identification information 12345678 does not exist in the management information table, the PC 15 records the identification information 12345678 in the identification information field of the record target record.

Further, the PC 15 determines whether or not the color difference between the color value C # 1 of the initial color and the measured color value Ct in the color change region 21 of the CI exceeds the threshold value. The PC 15 records OK in the pre-sterilization subfield if the color difference between the color value C # 1 and the measured color value Ct does not exceed the threshold value. FIG. 9A shows this state. If the color difference between the color value C # 1 and the measured color value Ct exceeds the threshold value, the PC 15 records NG in the pre-sterilization subfield. At the same time, the PC 15 displays on the display unit whether or not the color difference between the color value C # 1 and the measured color value Ct exceeds the threshold value. Further, when the color difference between the color value C # 1 and the measured color value Ct of the CI exceeds the threshold value, it can be displayed on the display unit that the CI cannot be used in a later step. Based on the information displayed on the display unit of the PC 15, the operator encloses the measured CI in the set or discards it to measure a different CI.

Subsequently, the operator places the set in the sterilization processing apparatus 13 in the sterilization step. At that time, the operator inputs the zone of the sterilization processing apparatus 13 in which the set is arranged into the management system 100. As a result, the management system 100 records the information in the arrangement position field of the record corresponding to the set. After that, the operator operates the sterilization processing device 13 to sterilize the set. The management system 100 acquires the completion date and time of the sterilization process from the sterilization process device 13 and records it in the sterilization date and time field of the record corresponding to the set. FIG. 9B shows this state. After that, when the set is used in the surgical step, the discolored region 21 of the CI enclosed in the set is measured by the measuring device 1. As a result, the measuring device 1 outputs the measured color value Ct of the discolored region 21 and the identification information 12345678 to the PC 15 as the measurement result. The PC 15 determines the level of achievement of the sterilization process based on the measured color value Ct, and records the determined level in the post-sterilization subfield of the record corresponding to the identification information 12345678. FIG. 9C shows this state.

The zone in which the set is arranged is not limited to the configuration in which the operator confirms and inputs the set to the management system 100. For example, the sensor provided in the sterilization processing device 13 may be configured to detect the zone in which the set is arranged in the sterilization processing device 13 and notify the management system 100. Alternatively, after arranging the set in the sterilization processing apparatus 13, the arrangement state may be imaged by an image sensor such as a camera, the image captured by the PC 15 may be read, and the PC 15 may be determined by the image recognition technique.

FIG. 10 shows an example of a graph created based on management information. The management system 100 can present, for example, the graph shown in FIG. 10 to the user. FIG. 10 shows the transition of the level indicated by the post-sterilization field of the record in which the values of the set field and the sterilization apparatus field are X1 and Y1, respectively, for each zone in which the set is arranged. The horizontal axis is the value of the sterilization date and time field. The straight line of the alternate long and short dash line in FIG. 10 shows the average of the levels indicated by the points of Zone A to Zone C excluding Zone D. Further, the broken straight line in FIG. 10 indicates a level that is smaller than the average by three times the standard deviation of the level indicated by the points of Zone A to Zone C excluding Zone D. In FIG. 10, it can be seen that the degree of achievement of the sterilization process when the set of type X1 is placed in zone D is far from the standard data distribution. From FIG. 10, it can be seen that when the set of type X1 is sterilized by the sterilization processing apparatus 13, it should be arranged in any of zones A, B and C instead of being arranged in zone D.

Therefore, when the operator inputs to the management system 100 that the set of the type X1 is arranged in the zone D of the sterilization processing apparatus 13 specified by Y1 in the sterilization process, the management system 100 may issue a warning. it can. The warning may include a message that the set of type X1 cannot be placed in zone D. Further, the management system 100 can replace the set of the type X1 in the zone D, or in addition, present the user with a zone in which the set of the type X1 can be placed. The method of determining the combination of the set type and the zone that cannot be used is determined according to a predetermined standard. For example, the management system 100 obtains the average value, the minimum value, and other statistical values of the achievement level for the combination of the set type and the zone, and uses the combination in which the average value, the minimum value, and the statistical value are smaller than the threshold value. It can be determined that the combination cannot be performed. The record used to determine the combination that cannot be used may be a predetermined period in the past or a predetermined number in the past.

Regardless of the type of set, if the level of achievement in the sterilization process in a specific zone such as zone D is low, the management system 100 determines that there is a problem in the sterilization process device 13 specified by Y1. Then, the user can be urged to adjust / repair the sterilization processing apparatus 13 specified by Y1. The straight line of the broken line in FIG. 10 is set to 3 times the standard deviation, but how many times the standard deviation should be set is arbitrarily determined according to the probability to be obtained.

FIG. 11 shows a graph similar to that of FIG. The management system 100 can present, for example, the graph shown in FIG. 11 to the user. The approximate straight line shown by the alternate long and short dash line in FIG. 11 is a straight line that linearly approximates each point indicating the transition of the level of zone C. The approximate straight line can be obtained by various statistical methods such as the least squares method. In the present embodiment, the transition of the level of the zone C is approximated by a linear function, but any relational expression can be used, and therefore, an approximate curve can be used instead of an approximate straight line. From the approximate straight line shown in FIG. 11, it can be seen that the degree of achievement of the sterilization treatment for the set arranged in the zone C decreases with the passage of time. In addition, by extending the approximate straight line from the present time to a future time point, it is possible to determine what the level of sterilization treatment will be in the future if the current tendency continues. For example, in FIG. 11, level # 3 is set as a threshold value, and the level of sterilization treatment for the set arranged in zone C is averaged around the date and time corresponding to the intersection of the straight line (threshold value) corresponding to the threshold value and the approximate straight line. It can be predicted that it will reach level # 3. In this case, the management system 100 can present the predicted date and time to the user. Therefore, although the NG level has not been reached at this time, if it is predicted that the NG level may occur in the future, the user should take measures such as adjusting / repairing the sterilization processing apparatus 13 before the NG level is obtained. Can be done.

In the present embodiment, the arrangement area of the sterilization processing apparatus 13 is divided to define a plurality of zones, and the information indicating the zones is recorded in the management information table. However, more generally, the position information indicating the arrangement position where the set is arranged in the arrangement area can be recorded in the management table. For example, it is possible to define the coordinates of a predetermined resolution in the arrangement area and record the coordinates of the predetermined position of the arranged set in the management table as the position information. It should be noted that this also corresponds to the fact that the size of the zone is made smaller than the size of the set.

As described above, during the sterilization process, the position information indicating the arrangement position where the sterilized object is arranged is recorded. For example, as described with reference to FIG. 8, the position information can indicate a zone. As a result, the management system 100 can generate information for determining the relationship between the placement position and the degree of achievement of the sterilization process. In addition, by recording the information on the date and time of sterilization, it is possible to generate information for determining the transition of the achievement level of the sterilization process for each of the arrangement positions. Further, by recording the information indicating the type of the set, it is possible to generate the determination information for determining the relationship between the arrangement position and the degree of achievement of the sterilization process for each type of the set. Furthermore, by recording the information that identifies the sterilization treatment device that has been sterilized, the judgment information for determining the relationship between the placement position and the achievement level of the sterilization treatment for each set type and combination of sterilization treatment devices. Can be generated.

In the above embodiment, the information for specifying the sterilization processing device 13 is recorded in the management information table, but instead or additionally, the information for specifying the type of the sterilization processing device 13 may be recorded. it can. As a result, it is possible to generate determination information for determining the relationship between the arrangement position and the degree of achievement of the sterilization process for each combination of the set type and the type of the sterilization process device. Therefore, for example, it is possible to take measures such as avoiding placement at a placement position where the degree of achievement of sterilization treatment for the set is low. It is also possible to determine whether the sterilization apparatus 13 needs to be adjusted / repaired.

Further, the management system 100 can determine the unused combination of the set type and the arrangement position based on the determination information. The combination may be a combination of the set type, the sterilization treatment device and the placement position, or a combination in which the set type, the sterilization treatment device type and the placement position are not used. The management system 100 can warn the user when a combination determined not to be used is input to the management information. The warning may include a message telling the user that the combination entered is not available or that the combination is available. With the above configuration, it is possible to maintain high quality of sterilization treatment.

<Second embodiment>
Subsequently, the second embodiment will be described focusing on the differences from the first embodiment. In this embodiment, a floor area ratio field is provided instead of the arrangement position field of FIG. The floor area ratio is the ratio (ratio) of the total volume of the entire set arranged in the sterilization treatment device 13 for the sterilization treatment to the volume of the arrangement area of the sterilization treatment device 13. For example, by obtaining the volume of each type of set in advance, the total volume of the set arranged in the sterilization processing apparatus 13 can be calculated based on the number of each type of set arranged in the sterilization processing apparatus 13. .. The management system records in the floor area ratio field of the record the floor area ratio when the set corresponding to the record is sterilized by the sterilization processing apparatus 13.

FIG. 12 shows an example of a graph created based on the management information of the present embodiment. The management system 100 can present, for example, the graph shown in FIG. 12 to the user. FIG. 12 shows the transition of the level indicated by the post-sterilization field of the record in which the values of the set field and the sterilization apparatus field are X1 and Y1, respectively, for each range of the floor area ratio. The horizontal axis is the value of the sterilization date and time field. The straight line of the alternate long and short dash line in FIG. 12 shows the average of the levels indicated by the points having a floor area ratio of 0 to 75%. Further, the broken line in FIG. 12 indicates a level that is smaller than the average by three times the standard deviation of the level indicated by the points having a floor area ratio of 0 to 75%. In FIG. 12, it can be seen that the degree of achievement of the sterilization treatment performed at a floor area ratio of 75% or more is far from the standard data distribution. From FIG. 12, it can be seen that when the set of type X1 is sterilized by the sterilization processing apparatus 13 specified by Y1, the volume ratio should be less than 75%. Further, when the operator sterilizes the set of type X1 with the sterilization apparatus 13 specified by Y1, if a value of 75% or more is entered in the floor area ratio field, the management system 100 warns the user. Can be presented. The warning may include a message to the user that the set of type X1 should have a volume ratio of less than 75% when sterilized by the sterilization apparatus 13 specified by Y1. The straight line of the broken line in FIG. 12 is set to 3 times the standard deviation, but how many times the standard deviation should be set is arbitrarily determined according to the probability to be obtained.

As described above, the information indicating the floor area ratio during the sterilization process is recorded. This makes it possible to generate information for determining the relationship between the floor area ratio and the degree of achievement of the sterilization process. As in the first embodiment, the relationship between the floor area ratio and the achievement level of the sterilization treatment is determined for each change in the achievement level for each range of the floor area ratio, the type of the set, and the individual or type of the sterilization treatment device 13. Judgment information can also be generated. Therefore, for example, it is possible to determine a set in which the achievement level of the sterilization treatment is not affected even if the floor area ratio is high, a set in which the achievement level of the sterilization treatment is low when the floor area ratio is high, and the like.

Further, as in the first embodiment, the management system 100 can determine the combination of the set type and the floor area ratio that is not used, based on the determination information. The combination may be a combination of a set type, a floor area ratio, and a sterilization treatment device, or a combination of a set type, a floor area ratio, and a sterilization treatment device type. The management system 100 can warn the user when a combination determined not to be used is input to the management information. The warning may include a message telling the user that the combination entered is not available or that the combination is available. In this way, in order to maintain a high degree of achievement of the sterilization process, it is possible to select a set to be sterilized at once by the sterilization process device 13 according to the type of the set, and it is possible to maintain a high quality of the sterilization process. become. The upper limit of the floor area ratio may be input to the management system 100 by the user. The upper limit value can be, for example, a value recommended by the manufacturer of the sterilization processing apparatus. Then, the management system 100 can warn the user when the floor area ratio exceeding the upper limit value is input to the floor area ratio field. The warning may include a message telling the user that the floor area ratio entered has exceeded the upper limit.

<Third Embodiment>
Next, the third embodiment will be described focusing on the differences between the first embodiment and the second embodiment. FIG. 13 shows a management information table of this embodiment. In this embodiment, the management information table has both a placement position field and a floor area ratio field, and records both the zone in which the set is placed and the floor area ratio in the sterilization process.

14 and 15 show an example of a graph created based on the management information of this embodiment. The management system 100 can present, for example, the graphs shown in FIGS. 14 and 15 to the user. The horizontal axis of FIGS. 14 and 15 is the floor area ratio, and the vertical axis shows the level of achievement of the sterilization process. Note that FIG. 14 shows the relationship between the floor area ratio of the set arranged in the zone A and the level of achievement for each type of set. FIG. 15 shows the relationship between the floor area ratio of the set arranged in the zone B and the level of achievement for each type of set. From FIG. 15, it can be seen that in Zone B, the achievement level of the sterilization treatment is maintained at a high level regardless of the floor area ratio. On the other hand, in Zone A, it can be seen that the degree of achievement of the sterilization treatment for the set of type X2 decreases significantly as the floor area ratio increases. From the graphs of FIGS. 14 and 15, when the sets of types X1 and X2 are simultaneously sterilized by the sterilization processing apparatus 13, the set of type X1 should be arranged in zone A and the set of type X2 should be arranged in zone B. I understand. Further, from FIG. 15, when the floor area ratio is a predetermined value, for example, 50% or more, and the user inputs that the set of the type X2 is arranged in the zone A, the management system 100 zone the set of the type X2. It is possible to show the user that it should be placed in B or that the set of type X2 cannot be placed in zone A.

As described above, both the placement position where the sterilized object is placed and the floor area ratio are recorded. As a result, it is possible to generate determination information for determining the relationship between the combination of the arrangement position and the volume ratio and the degree of achievement of the sterilization process. Further, as in the above embodiment, information for determining the relationship between the combination of the arrangement position and the floor area ratio and the achievement level of the sterilization treatment is generated for each type of the set and the individual or type of the sterilization treatment apparatus 13. be able to.

Further, as in the first embodiment and the second embodiment, the management system 100 can determine the unused combination of the set type, the arrangement position, and the floor area ratio based on the determination information. The combination may further include a sterilization treatment device and a type of sterilization treatment device. The management system 100 can warn the user when a combination determined not to be used is input to the management information. The warning may include a message telling the user that the combination entered is not available or that the combination is available. With the above configuration, it is possible to avoid combinations that can lower the quality of the sterilization treatment and maintain the quality of the sterilization treatment high.

<Fourth Embodiment>
Subsequently, the fourth embodiment will be described focusing on the differences from the above-described embodiments. Normally, in order to confirm whether the sterilization process has been performed normally in the sterilization processing device 13, in addition to the CI enclosed in the set, the part inside the sterilization processing device 13 where sterilization is most difficult to be performed (hereinafter, cold spot). Also place a CI. Hereinafter, the CI that is not enclosed in the set and is arranged inside the sterilization processing apparatus 13 will be referred to as a PCD CI. When the sterilization process by the sterilization processing device 13 is completed, the CI for PCD is measured by the measuring device 1, and the degree of achievement of the sterilization process is determined based on the measured color value Ct of the discolored region 21 of the CI for PCD. In addition, the initial failure of the PCD CI is also determined.

In the present embodiment, in addition to the cold spot, a CI for PCD is arranged in each zone. Then, as shown in FIG. 16, the management information also records the determination result of the initial failure of the PCD CIs arranged in the same zone and the determination result of the achievement level determined based on the PCD CIs. In FIG. 16, the achievement level is not recorded, but whether the achievement level is OK or NG is recorded. For example, if both the achievement degree determination result determined from the PCD CI arranged in a certain zone and the achievement degree determination result determined from the set CI arranged in the zone are OK, the sterilization process is performed. Can be determined that there is no problem. On the other hand, if the judgment result based on the CI for PCD is OK, but the judgment result based on the CI of the set is NG, the sterilization condition outside the packaging member is satisfied, but the sterilization condition inside the packaging member is satisfied. You can see that it is not. In this case, it can be estimated that there is a problem in how to assemble the set. Further, if both the determination result based on the CI for PCD and the determination result determined from the CI of the set are NG, it can be seen that the sterilization condition outside the packaging member is not satisfied. In this case, it can be estimated that there is a problem such as a failure of the sterilization processing device 13 or an overload of the set.

In the present embodiment, the PCD CI is arranged in each zone, but the PCD CI may be arranged in at least one of the plurality of zones. In this case, among the zones in which the PCD CIs are arranged, the determination result of the PCD CIs in the zone closest to the zone in which the set corresponding to the record is arranged is recorded in the record corresponding to the set. .. More generally, the determination result of the PCD CI arranged at the position closest to the arrangement position of the set is recorded in the record corresponding to the set.

As described above, one or more PCD CIs are arranged in the arrangement area, and the achievement level determined by the PCD CIs is recorded. The management system 100 compares the achievement level based on the CI and the achievement level based on the CI for PCD of the same record, and presents the comparison result to the user. As a result, it is possible to determine whether or not there is a problem in the way the set is assembled or the packaging, and it is possible to take necessary measures. Therefore, the quality of the sterilization process can be maintained high.

<Fifth Embodiment>
Subsequently, the fifth embodiment will be described focusing on the differences from the first embodiment. Also in the present embodiment, as in the first embodiment, a plurality of sub-regions (zones) are defined by dividing the arrangement region in which the set is arranged in the sterilization processing apparatus 13. The size of each zone is set so that a plurality of sets do not fit in one zone. FIG. 17 shows a state in which the upper and lower arrangement areas are each divided into 6 zones, that is, a total of 12 zones P1 to P12.

FIG. 18 shows a management information table (sterilization record table) which is management information held by the server device 14 in the present embodiment. When the set is sterilized, the arrangement position field stores information indicating a zone in the sterilization apparatus 13 in which the set is arranged. For a set that is arranged across a plurality of zones, all the zones that are straddled are recorded. The records of numbers 300 to 306 in FIG. 18 correspond to the seven sets of records of FIG. 17, respectively. For example, the set of type X1 on the upper left side is arranged in zones P1 and P2 and corresponds to the record of number 300. Further, the set of the type X3 on the lower left side is arranged in the zones P7 and P8, and corresponds to the record of the number 303.

Further, in the present embodiment, the sterilization job number field is provided in the management information table. Then, the same value is stored in the sterilization job number field of the set that is sterilized by one and the same sterilization apparatus 13 at the same time. The management system 100 can identify sets that have been sterilized simultaneously by the same sterilization apparatus 13 by the value in the sterilization job number field.

The management system 100 can specify which set and which set were adjacent to each other for a plurality of sets sterilized at the same time from the value of the placement position field. Specifically, from the value of the arrangement position field in FIG. 18, the management system 100 has a set of types X1 arranged across zones P1 and P2 and a set of types X2 arranged across zones P3 and P4. Can be identified as being adjacent. The same applies to other adjacencies.

The management system 100 determines the level of two sets of pairs arranged adjacently. In this embodiment, the level of this pair is defined as the lesser achievement level of the sterilization process of the two sets of the pair. For example, it is assumed that level # 8 is stored in the post-sterilization subfield of the record number 300 in FIG. 18 and level # 6 is stored in the post-sterilization subfield of the record number 301. In this case, the level of the pair of the set of the type X1 arranged across the zones P1 and P2 and the set of the type X2 arranged across the zones P3 and P4 is # 6.

The management system 100 can present the user with the same graphs as described in FIGS. 10 and 11 of the first embodiment for each pair. In addition, the management system 100 can obtain the average value of the paired levels. The record used to obtain the average value may be a predetermined period in the past or a predetermined number in the past. FIG. 19 shows the average value of each pair of levels. As shown in FIG. 19, it can be seen that the average value of the levels of the pair X1 and the type X3 is lower than the average value of the levels of the other pairs. For example, the management system 100 can determine that a pair whose average value is smaller than a predetermined value (threshold value) is not used. Then, the management system 100 can warn the operator when an unused pair is input to the management information. For example, assuming that the threshold value is 4, the management system 100 determines that the set of the type X1 and the type X3 cannot be arranged adjacent to each other. The management system 100 determines the adjacency relationship in the sterilization processing apparatus 13 based on the values input in the set field and the placement position field when the operator inputs the record having the same sterilization job number. Then, when the set of the type X1 and the type X3 are arranged adjacent to each other, the management system 100 presents a warning to the user indicating that the set of the type X1 and the type X3 cannot be arranged adjacent to each other.

In this embodiment, there is no distinction between the case where the set of type X1 is on the right side of the set of type X2 and the case where the set of type X1 is on the left side of the set of type X2, and the set of type X1 and type X2 It was a pair. However, the case where the set of the type X1 is on the right side of the set of the type X2 and the case where the set of the type X1 is on the left side of the set of the type X2 can be made into different pairs. Further, although the level of the pair is the smaller of the levels of the two sets included in the pair, it can be the average value of the two levels. Further, the management system 100 determines the adjacency relationship based on the value of the placement position field. That is, the information of the arrangement position field of the present embodiment was the information for specifying the adjacency relationship. However, the adjacency relationship may be specified by recording the identification information of adjacent sets in a record. Further, the present invention is not limited to determining unused pairs based on the average value of the levels of each pair, and can be determined using arbitrary statistical values.

As described above, in the present embodiment, it is possible to generate determination information for determining the relationship between the adjacency relationship of the set type and the level relationship and present it to the user. As in the first embodiment, it is also possible to generate determination information for determining the relationship between the adjacency relationship and the degree of achievement of the sterilization process for each individual or type of the sterilization process device 13. Further, as in the first embodiment, the management system 100 can determine the unused adjacency relationship based on the determination information. Adjacent relationships that are not used can also be determined for each sterilization device or for each type of sterilization device. The management system 100 can warn the operator when the operator arranges the set in an unused adjacency. This configuration makes it possible to maintain high quality of sterilization.

<Sixth Embodiment>
Subsequently, the sixth embodiment will be described focusing on the differences from the fifth embodiment. In the present embodiment, as in the fifth embodiment, the sterilization job number field is provided in the management information table (sterilization record table). The placement position field may not be provided.

The management system 100 can identify the combination of types of sets that have been sterilized at the same time from the values in the sterilization job number field. Specifically, from the value of the sterilization job number field in FIG. 18, it can be specified that the management system 100 has sterilized the combinations of the types X1, X2 and X3 at the same time. That is, the information stored in the sterilization job number field is information for identifying a set that has been sterilized at the same time by the same sterilization processing apparatus 13.

Management system 100 determines the level of combinations that have been sterilized at the same time. In this embodiment, the level of combination is defined as the lowest level of each set that has been sterilized at the same time. For example, if the minimum value of the post-sterilized subfields of the records numbers 300 to 306 of FIG. 18 is level # 3, the level of the set combination shown in FIG. 17 is level # 3.

The management system 100 can present the user with the same graphs as described in FIGS. 10 and 11 of the first embodiment for each combination. In addition, the management system 100 can obtain the average value of the levels for each combination. The record used to obtain the average value may be a predetermined period in the past or a predetermined number in the past. FIG. 20 shows the average value of the levels of each combination. From FIG. 20, it can be seen that when the type X1 and the type X3 are included in the combination, the average value of the levels becomes low. For example, the management system 100 can determine a combination whose average value is smaller than a predetermined value (threshold value), and can determine a combination that does not use such a combination. Then, when the information is input to the record, the management system 100 determines the combination of sets to be sterilized based on the value stored in the sterilization job number field. Then, when this combination is included in the unused combination, the operator can be warned. Specifically, in the case of FIG. 20, the management system 100 can warn the user that a set of types X1 and type X3 is included in the combination.

In this embodiment, even if there are a plurality of sets of the same type, the number is not considered. However, it is also possible to make a combination in consideration of the number of sets. In this case, for example, the combination of FIG. 17 is a combination of 2 for X1, 3 for X2, and 2 for X3. This corresponds to determining a set combination rather than a set type combination. Further, the management system 100 has determined the combination of sets to be sterilized at the same time based on the value of the sterilization job number field. That is, the information in the sterilization job number field of this embodiment was information for identifying the combination. However, the combination may be specified by recording the identification information of the set to be sterilized at the same time in a record. Furthermore, the present invention is not limited to determining unused combinations based on the average value of the levels of each combination, and can be determined using arbitrary statistical values.

As described above, in the present embodiment, the relationship between the combination and the level of the set to be sterilized at the same time can be presented to the user. In addition, when a combination that lowers the level is determined and the worker arranges the set in such a combination, the worker can be warned. The combination may further include a sterilization treatment device and a type of sterilization treatment device. This configuration makes it possible to maintain high quality of sterilization.

<Seventh Embodiment>
Subsequently, the seventh embodiment will be described focusing on the differences from the first to sixth embodiments. In this embodiment, the CI shown in FIG. 21 is used. The CI shown in FIG. 21 has a temperature detection region 23 to 25 that changes color depending on the temperature, in addition to the color change region 21 and the identification unit 22. For example, the temperature detection region 23 is a region that changes color when the temperature reaches 125 degrees or higher, the temperature detection region 24 is a region that changes color when the temperature reaches 130 degrees or higher, and the temperature detection region 25 is a region that changes color when the temperature reaches 135 degrees or higher. This is a region that changes color when it reaches temperature. Therefore, if the temperature inside the sterilization apparatus 13 does not reach 125 degrees, the colors of the temperature detection regions 23 to 25 do not change. Further, when the temperature in the sterilization processing apparatus 13 is 125 degrees or more and less than 130 degrees, only the color of the temperature detection region 23 changes. Further, when the temperature in the sterilization processing apparatus 13 is 130 degrees or more and less than 135 degrees, the colors of the temperature detection regions 23 and 24 change, and the colors of the temperature detection regions 25 do not change. Further, when the temperature in the sterilization processing apparatus 13 becomes 135 degrees or higher, the colors of all the temperature detection regions 23 to 25 change. That is, by using the CI shown in FIG. 21, the maximum temperature in the sterilization process by the sterilization process device 13 can be detected. The number of temperature detection regions is not limited to three.

FIG. 22 shows a management information table (sterilization record table) which is management information held by the server device 14 in the present embodiment. According to FIG. 22, a "temperature" field is added to the management information table of the first embodiment shown in FIG. In the temperature field, the temperature detection result in the temperature detection areas 23 to 25 of CI is recorded. The temperature can be determined by the measuring device 1 measuring the colors of the temperature detection regions 23 to 25. According to FIG. 22, the record number 400 shows that the temperature is 125 degrees or higher and lower than 130 degrees. Also, the record number 402 shows that the temperature is less than 125 degrees.

The management system 100 can generate information for determining the temperature transition for each zone based on the management information table of FIG. Further, since the sterilization process is affected when the temperature is below the threshold value, the management system 100 can be configured to present a warning to the user when the temperature is below the threshold value. Further, similarly to FIG. 11, it is possible to predict the date and time when the temperature becomes equal to or lower than the threshold value and present the predicted date and time to the user.

In this embodiment, the temperature transition for each zone is determined, but in combination with the second embodiment, the temperature transition for each floor area ratio range can be determined. Further, in combination with the third embodiment, the temperature transition for each combination of the floor area ratio range and the zone can be determined. Further, in combination with the fifth embodiment and the sixth embodiment, the adjacency relationship of the set and the temperature of each combination can be determined. Further, each temperature detection region of CI can be configured so that the color changes when a predetermined temperature continues for a predetermined time or longer.

Further, instead of or in addition to the temperature detection region 25, a concentration detection region for detecting the concentration of the sterilizing agent may be provided. More generally, a detection region for detecting one or more predetermined physical quantities may be provided in the CI to determine the relationship between the zone or the like and one or more predetermined physical quantities.

<Eighth Embodiment>
Subsequently, the eighth embodiment will be described focusing on the differences from the first to seventh embodiments. The discoloration of the discolored region 21 of the CI may be affected by the position of the sterilized object and the CI in the packaging member and the relative positional relationship between the sterilized object and the CI. Therefore, in the present embodiment, the sterilized object and the arrangement area of the CI in the packaging member are also recorded in the management information table (arrangement area information). Similar to the zone in the sterilization processing apparatus, the inside of the packaging member is divided into a plurality of regions, and the region in the packaging member in which the CI is arranged and the region in the packaging member in which one or more sterilization objects are arranged are divided. Record. For one or more sterilized objects, record all areas where the sterilized objects are located.

With the above configuration, the management system 100 is for determining the relationship between the arrangement position of the set in the sterilization processing apparatus, the combination of the arrangement area of the CI and / or the object to be sterilized in the packaging member, and the achievement level of the sterilization processing. Information can be generated. In addition, by recording the information on the date and time of sterilization, it is possible to generate information for determining the transition of the achievement level of the sterilization process for each of the above combinations. Further, by recording the information indicating the type of the set, it is possible to generate the determination information for determining the relationship between the combination and the degree of achievement of the sterilization process for each type of the set. Furthermore, by recording the information that identifies the sterilization treatment device that has been sterilized, the judgment information for determining the relationship between the above combination and the achievement level of the sterilization treatment for each set type and combination of the sterilization treatment devices. Can be generated. By presenting the determination information to the user, it is possible to maintain high quality of the sterilization process.

<Ninth Embodiment>
Subsequently, the ninth embodiment will be described focusing on the differences from the eighth embodiment. Also in the present embodiment, as in the eighth embodiment, the arrangement area of the CI and / or the sterilization target in the packaging member is recorded in the management information table. Then, in the present embodiment, information for determining the relationship between the CI arrangement area in the packaging member and the achievement level is generated. Alternatively, information for determining the relationship between the combination of the CI placement area and the sterilization object placement area in the packaging member and the degree of achievement is generated. Further, as in the first embodiment, the arrangement area and achievement level of the CI and the sterilization object are determined for each of the set type, the sterilization treatment device, and the sterilization treatment device type, or any combination. Information for determining the relationship can be generated. The information to be generated can be, for example, the same as the one in which the zone in which the set is arranged in the first embodiment is replaced with the arrangement area of CI or the combination of the arrangement area of CI and the sterilization object.

When the type of packaging member is different for each type of set, the type of set corresponds to the type of packaging member. However, the same type of packaging member may be used for different types of sets. In this case, by recording the type of the packaging member in the management information table, it is possible to generate information for determining the relationship between the arrangement area of the CI or the sterilized object and the degree of achievement for each type of the packaging member. ..

Further, the management system 100 can determine, for example, an area in which the CI should be arranged in the packaging member based on the relationship between the CI arrangement area in the packaging member and the achievement level. The area to be arranged can be determined for each set type, any of the sterilization treatment apparatus and the sterilization treatment apparatus type, or any combination thereof. Further, the type of packaging member may be used instead of the type of set. The area to be arranged can be determined in the same manner as the determination of the unused arrangement position in the first embodiment. In addition, unlike the first embodiment, in the present embodiment, the degree of achievement determined is the smallest, or the inside of the packaging member is smaller than the threshold value determined based on the relationship between the CI arrangement area and the degree of achievement. Decide that CI should be placed in the area. This is to avoid overestimating the achievement of sterilization for the set. Further, the management system 100 can determine, for example, an area in the packaging member to which the sterilization object should be arranged based on the relationship between the arrangement area of the sterilization object and the degree of achievement in the packaging member. The area in the packaging member where the object to be sterilized should be placed is the area in the packaging member where the degree of achievement to be determined is high.

Further, the management system 100 warns the user that the arrangement area in the packaging member of the CI or the sterilization object input in the management information is a different area from the area to be arranged, as in the above embodiment. be able to. The warning may include a message telling the user which area to place. With the above configuration, it is possible to maintain high quality of sterilization treatment.
