[0004] [Patent Document 1] JP 2017-148113 A Summary of the Invention [Problem to be solved by the invention]

[0005] In the storage process, the medical instruments are stored, for example, on a specified shelf. The shelf is divided, for example, into a plurality of areas, and each area is assigned a shelf number. It is preset which shelf and which shelf number the medical instruments should be stored in. However, since the medical instruments are stored manually by an operator, some operators may not store the medical instruments in the shelf and shelf number that is preset, resulting in a mistake in the storage location of the medical instruments.

[0006] The present invention has been made in consideration of the above points, and its object is to provide a medical instrument storage management device and a storage management system that can prevent workers from selecting the wrong storage location for medical instruments. [Means for solving the problem]

[0007] The medical instrument storage management device according to the present invention includes a memory and at least one processor. The storage management device stores storage destination information in which an identification ID for identifying an instrument set that includes one or more medical instruments is associated with a shelf ID attached to the shelf number of a shelf storing the instrument set. The storage management device is configured to be able to execute a shelf acquisition process, an instrument acquisition process, a shelf extraction process, a shelf determination process, and a shelf error notification process. In the shelf acquisition process, a target shelf ID attached to the shelf number of a shelf where the instrument set is to be stored is acquired. In the instrument acquisition process, a target identification ID for identifying the instrument set to be stored is acquired. In the shelf extraction process, the shelf ID associated with the identification ID that matches the target identification ID is extracted from the storage destination information and set as an extracted shelf ID. In the shelf determination process, it is determined whether the extracted shelf ID matches the target shelf ID. In the shelf error notification process, when it is determined in the shelf determination process that the extracted shelf ID does not match the target shelf ID, a shelf error notification is issued for the instrument set identified from the target identification ID.

[0008] According to the medical instrument sterilization management device of the present invention, the storage destination information includes a shelf ID assigned to the shelf number of a shelf that is an appropriate storage destination for the instrument set identified by the identification ID, and the shelf ID is associated with the identification ID. Here, when storing the instrument set, a shelf ID corresponding to the target identification ID of the instrument set that the operator is going to store is extracted from the storage destination information and set as the extracted shelf ID. Then, it is determined whether the target shelf ID assigned to the shelf number of the shelf where the operator is going to store the instrument set matches the extracted shelf ID. Here, if the target shelf ID and the extracted shelf ID do not match, it is determined that the shelf number of the shelf where the operator is going to store the instrument set is not appropriate, and a notice of a shelf error is issued. By being notified of the shelf error, the operator can notice the shelf error before storing the instrument set. This makes it possible to prevent the operator from storing the instrument set in a wrong storage destination in advance. Effect of the Invention

[0009] According to the present invention, it is possible to provide a medical instrument storage management device and a storage management system that can prevent an operator from selecting the wrong storage location for a medical instrument. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, a storage management system including a medical instrument storage management device (hereinafter, simply referred to as a storage management device) according to the present invention will be described with reference to the drawings. Note that the embodiment described here is not intended to limit the present invention in any particular way.

[0012] 1 is a schematic diagram showing a storage management system 100 according to this embodiment. The storage management system 100 is a system used when storing medical instruments 5 in a shelf number 3 on a predetermined shelf 2.

[0013] The medical instrument 5 is an instrument used in medical procedures performed in medical settings such as hospitals. A medical procedure refers to a medical procedure performed by a doctor on a patient. Medical procedures include, for example, surgery and medical examinations.

[0014] The medical instruments 5 include, for example, trocars, forceps, incision devices, irrigation and suction devices, scissors, scalpels (e.g., laser scalpels and electric scalpels), ultrasonic cutters, scalpel holders, cannulas, tweezers, retractors, scales, probes, elevators, raspers, suction tubes, chest retractors, chest closure devices, needle holders, syringes, metal balls, pus trays, cups, pins, mirrors, files, mouth openers, clamps, handpieces, elevators, chisels, sharp spoons, disseminators, mirrors, suture needles, stuns, water receivers, needles, indenters, bougies, ventilation tubes, bone fragment driving rods, reuels, radio pliers, hammers, goniometers, thermometers, perforators, droppers, metal cotton swabs, enema devices, syringes, and endoscopes. However, the above examples are merely a partial list of the medical instruments 5. The medical instruments 5 are not limited to the above examples.

[0015] The medical instrument 5 may be composed of one part or multiple parts. Examples of the medical instrument 5 composed of multiple parts include a trocar, forceps, incision device, and irrigation and suction device used in laparoscopic surgery. Such a medical instrument 5 includes multiple components, and is collected after surgery, for example, and disassembled into the multiple components. Here, the components that compose the medical instrument 5 are referred to as components. In addition, when a component is further composed of multiple components, all of them are referred to as components.

[0016] Fig. 2 is an explanatory diagram of the circulation cycle 10. As shown in Fig. 2, the medical instrument 5 can be repeatedly used in a predetermined circulation cycle 10. The number of repetitions of the circulation cycle 10 for one medical instrument 5 is not particularly limited, and is appropriately determined depending on the type of the medical instrument 5 and the types of components that make up the medical instrument 5. In this embodiment, the circulation cycle 10 has a surgery / examination process 11, a collection process 12, a cleaning process 13, an assembly process 14, a sterilization process 15, and a storage process 16.

[0017] The surgery / examination process 11 is a process for performing surgery or examination, which is an example of a medical procedure, using a medical instrument 5. In the surgery / examination process 11, the medical instrument 5 stored in the shelf number 3 (see FIG. 1) of a specific shelf 2 arranged in a specific storage location is dispensed (in other words, taken out), and the surgery or examination is performed using the dispensed medical instrument 5.

[0018] The recovery step 12 is a step performed after the surgery / examination step 11. The recovery step 12 is a step of recovering the medical instrument 5 used in the surgery or examination. When the medical instrument 5 is composed of multiple components, the recovery step 12 may include a task of disassembling the medical instrument 5 into the individual components.

[0019] The cleaning step 13 is a step performed after the collecting step 12. The cleaning step 13 is a step of cleaning the medical instruments 5 collected in the collecting step 12 or individual components of the medical instruments 5. In the cleaning step 13, the medical instruments 5 are cleaned using, for example, a cleaner not shown.

[0020] The assembly step 14 is a step carried out after the cleaning step 13. The assembly step 14 is a step of assembling the components of the medical instrument 5 cleaned in the cleaning step 13 to complete one medical instrument 5. The assembly step 14 is a step of assembling a medical instrument 5 made up of multiple components. For example, in the case of a medical instrument 5 made up of a single component or a medical instrument 5 that was not disassembled in the recovery step 12, the assembly step 14 may be omitted.

[0021] The sterilization process 15 is a process carried out after the assembly process 14. The sterilization process 15 is a process for sterilizing the medical instrument 5 assembled in the assembly process 14. In the sterilization process 15, the medical instrument 5 is sterilized using, for example, a sterilizer (not shown). Hereinafter, the sterilization process is also simply referred to as sterilization.

[0022] The storage step 16 is a step performed after the sterilization step 15. In the storage step 16, the sterilized medical instruments 5 are stored in the shelf number 3 of a specified shelf 2 arranged in a specified storage location (see FIG. 1). Herein, storing the medical instruments 5 in the shelf number 3 of the shelf 2 means placing the medical instruments 5 in an area of ​​the shelf 2 with the specified shelf number 3. Hereinafter, storing the medical instruments 5 in the shelf number 3 of the specified shelf 2 will be referred to as storing. After the storage step 16, the surgery / examination step 11 is performed.

[0023] In the circulation cycle 10 according to this embodiment, each process is performed in units of an instrument set 8 shown in FIG. 1. Here, an instrument set 8 is a collection of one or more medical instruments 5. There is no particular limitation on the method of dividing the multiple medical instruments 5 into one or more instrument sets 8. The number and types of medical instruments 5 included in an instrument set 8 are determined for each medical site, such as a hospital, and may be determined based on the experience of staff at the medical site, such as doctors, nurses, and operators of each process of the circulation cycle 10.

[0024] For example, an instrument set 8 is a collection of one or more medical instruments 5 used in one medical procedure (e.g., surgery or examination). The number of instrument sets 8 used in one surgery or examination may be one or more. The medical instruments 5 included in one instrument set 8 are stored in a storage step 16 (see FIG. 2) in a sealed state in a predetermined packaging material, for example, contained in a tray (not shown).

[0025] In this embodiment, when one or more medical instruments 5 constituting an instrument set 8 are sterilized in the sterilization step 15 shown in FIG. 2, a sterilization label 20 as shown in FIG. 1 is issued. When the one or more medical instruments 5 constituting the instrument set 8 are sterilized in a state where they are placed in a predetermined packaging material, the sterilization label 20 is attached to, for example, the above-mentioned predetermined packaging material after the sterilization. As shown in FIG. 1, a sterilization identification mark 21 is attached to the sterilization label 20. The sterilization identification mark 21 is read by a reading device 30 described later. The type of the sterilization identification mark 21 is not particularly limited. For example, the sterilization identification mark 21 may be a one-dimensional code, a two-dimensional code, or an IC tag.

[0026] The sterilization identification label 21 records, for example, a target sterilization ID 22. The target sterilization ID 22 is an ID that is assigned to the sterilized instrument set 8 when the instrument set 8 is sterilized. Therefore, by assigning the target sterilization ID 22, it is possible to know that the instrument set 8 has been sterilized. This target sterilization ID 22 is a unique ID that is assigned to the instrument set 8 each time it is sterilized. Therefore, the instrument set 8 can be identified from the target sterilization ID 22. In this embodiment, a new target sterilization ID 22 is assigned to one instrument set 8 each time it is sterilized. The target sterilization ID 22 assigned to the instrument set 8 is changed each time it is used in surgery or examination and is sterilized. In this embodiment, the target sterilization ID 22 is an example of a target identification ID of the present invention.

[0027] In this embodiment, in the storage step 16 in FIG. 2, the instrument sets 8 are stored in units of instrument sets 8. For example, as shown in FIG. 1, a plurality of shelves 2 are arranged in a storage location for storing the instrument sets 8. Each shelf 2 has a plurality of shelf numbers 3. For example, each shelf 2 is divided into a plurality of areas, and a different shelf number 3 is assigned to each area. In this embodiment, it is preset which type of instrument set 8 is stored in the shelf number 3 of each shelf 2. Which type of instrument set 8 is stored in which shelf number 3 of which shelf 2 is not particularly limited, and is determined for each medical site, such as a hospital, and may be determined based on the experience of staff at the medical site, such as doctors, nurses, and operators of the storage step 16.

[0028] In this embodiment, a shelf identification sign 25 is affixed to each shelf number 3 of each shelf 2. The shelf identification sign 25 is read by a reading device 30. The type of shelf identification sign 25 is not particularly limited. For example, the shelf identification sign 25 is read by a reading device 30. The type of shelf identification sign 25 is not particularly limited, but is, for example, the same type as the sterilization identification sign 21. The shelf identification sign 25 may be a one-dimensional code, a two-dimensional code, or an IC tag.

[0029] A target shelf ID 26 is recorded in the shelf identification label 25. The target shelf ID 26 is a unique ID assigned to each shelf number 3 on the shelf 2. The target shelf ID 26 assigned to the shelf number 3 on the shelf 2 is immutable. By reading this target shelf ID 26, the shelf number 3 on the shelf 2 can be identified from the target shelf ID 26.

[0030] As described above, the instrument set 8 is repeatedly subjected to each step of the circulation cycle 10 in FIG. 2 in sequence. However, depending on the instrument set 8, the sterilization step 15 and the storage step 16 may be interchanged. An instrument set 8 in which the sterilization step 15 and the storage step 16 are interchanged and the steps of the circulation cycle are repeatedly performed in sequence is called a post-sterilization instrument set 8a as shown in FIG. 1. For the post-sterilization instrument set 8a, the storage step 16 is performed after the assembly step 14, and then the sterilization step 15 is performed. After being sterilized in the sterilization step 15, the post-sterilization instrument set 8a is used in the operation / examination step 11. That is, after being used in a medical procedure such as an operation or examination, the post-sterilization instrument set 8a is stored in the storage step 16 without being sterilized. After being removed from the storage location, the post-sterilization instrument set 8a is sterilized and used in a medical procedure such as an operation or examination.

[0031] In this embodiment, it is preset that the post-sterilization instrument set 8a is stored in the shelf number 3 of the dedicated shelf 2. Hereinafter, the shelf number 3 of the shelf 2 that stores an instrument set 8, such as the post-sterilization instrument set 8a, that is sterilized after storage and used in surgery or examination, is referred to as the shelf number 3a of the post-sterilization shelf 2a. Also, the target shelf ID 26 assigned to the shelf number 3 of the post-sterilization shelf 2a is referred to as the post-sterilization shelf ID 26a.

[0032] 2, the instrument set 8 is stored in a predetermined shelf 2 at shelf number 3. However, since the instrument set 8 is stored manually by an operator, some operators may not store the instrument set 8 in the predetermined shelf 2 at shelf number 3, and may store the instrument set 8 in a wrong location. Hereinafter, storing the instrument set 8 in a wrong location is referred to as a "shelf mistake."

[0033] Furthermore, in this embodiment, the instrument sets 8 other than the post-sterilization instrument set 8a are stored after being sterilized. An expiration date is set for the sterilization, and it is preferable that an instrument set 8 whose sterilization expiration date has expired is not stored. Conventionally, an operator must know whether or not each instrument set 8 has been sterilized, and some operators may mistakenly store an instrument set 8 that has not been sterilized. Conventionally, an operator must know the expiration date of the sterilization of each instrument set 8, and some operators may mistakenly store an instrument set 8 whose sterilization expiration date has expired.

[0034] In this embodiment, the storage management system 100 shown in Fig. 1 manages the entry of the instrument set 8 in the storage process 16 (see Fig. 2), and also judges whether the instrument set 8 is on the wrong shelf, whether it has been sterilized, and the expiration date of the sterilization. If the instrument set 8 is on the wrong shelf, if sterilization has not been performed, or if the expiration date of the sterilization has expired, a notification is given before the instrument set 8 is actually stored.

[0035] In this embodiment, the storage management system 100 includes a reading device 30, a display device 50, an operation device 55, and a storage management device 60.

[0036] The reading device 30 is operated by an operator, and reads the sterilization identification mark 21 on the sterilization label 20 attached to the instrument set 8, thereby reading the target sterilization ID 22. Furthermore, the reading device 30 is also capable of reading the target shelf ID 26 by reading the shelf identification mark 25 attached to the shelf number 3 of the shelf 2. Although not shown in the figure, the reading device 30 is provided with a handle that can be held by the operator's hand.

[0037] The type of the reading device 30 is not particularly limited, and may be any type capable of reading the target sterilization ID 22 of the sterilization identification mark 21 and the target shelf ID 26 of the shelf identification mark 25. For example, when the sterilization identification mark 21 and the shelf identification mark 25 are two-dimensional codes, the reading device 30 may be a two-dimensional code reader capable of reading two-dimensional codes. For example, when the sterilization identification mark 21 and the shelf identification mark 25 are IC tags, the reading device 30 may be an IC tag reader. In this embodiment, the reading device 30 is a non-contact type device. However, the reading device 30 may be a contact type device. The number of reading devices 30 used in the storage process 16 may be one or more. The installation location of the reading device 30 is, for example, a storage location where the shelf 2 on which the instrument set 8 is stored in the storage process 16 is arranged.

[0038] The display device 50 displays a screen used when storing the instrument set 8 in the storage process 16. The type of the display device 50 is not particularly limited. For example, the display device 50 may be a display of a mobile terminal. The display device 50 may be a display of a desktop or notebook type (in other words, laptop type) personal computer.

[0039] The operation device 55 is used when an operator operates a screen displayed on the display device 50. For example, the operator can switch the screen displayed on the display device 50 by operating the operation device 55. In addition, the operator can register in the storage management device 60 which shelf 2 and shelf number 3 the tool set 8 is to be stored in by operating the operation device 55. The type of the operation device 55 is not particularly limited. For example, the operation device 55 is a keyboard and mouse of a personal computer. However, the operation device 55 may be a touch panel provided on the display device 50. In this embodiment, the number of the display device 50 and the operation device 55 is one each, but each may be multiple.

[0040] Next, the storage management device 60 according to this embodiment will be described. The storage management device 60 manages the storage of the instrument set 8 in the storage process 16 (see FIG. 2), that is, the history of storage. This makes it possible to manage when the instrument set 8 was stored in the shelf number 3 of a specific shelf 2. The storage management device 60 also notifies of the instrument set 8 being stored on a wrong shelf or the expiration of the sterilization treatment. The storage management device 60 is a computer control device. FIG. 3 is a block diagram of the storage management device 60. As shown in FIG. 3, the storage management device 60 includes a memory 60a and at least one processor 60b. The processor 60b may be one or more. For example, the processor 60b uses a program stored in the memory 60a to execute processing. The storage management device 60 may be realized by a dedicated computer or a general-purpose computer.

[0041] In this embodiment, the storage management device 60 is communicatively connected to the reading device 30 as shown in Fig. 1. The storage management device 60 may be connected to the reading device 30 by wire or wirelessly. The storage management device 60 is communicatively connected to the display device 50 and the operation device 55. The storage management device 60, the display device 50, and the operation device 55 may be realized by one personal computer.

[0042] Here, the storage management system 100 may be realized by a so-called client-server system, or may be realized by cloud computing. Also, the storage management system 100 may be realized by a so-called stand-alone system.

[0043] 3, the storage management device 60 includes a memory unit 61, a display unit 63, a sterilization acquisition unit 65, a shelf acquisition unit 67, a judgment unit 69, a notification unit 71, a list addition unit 73, and a history addition unit 75. The storage management device 60 further includes a shelf extraction unit 81, a shelf judgment unit 82, a wrong shelf notification unit 83, a sterilization judgment unit 84, a non-sterilization notification unit 85, a deadline extraction unit 86, a date acquisition unit 87, a deadline judgment unit 88, an expiration notification unit 89, and a post-sterilization judgment unit 90.

[0044] The storage unit 61 is stored in the memory 60a. The display unit 63, the sterilization acquisition unit 65, the shelf acquisition unit 67, the judgment unit 69, the notification unit 71, the list addition unit 73, the history addition unit 75, the shelf extraction unit 81, the shelf judgment unit 82, the wrong shelf notification unit 83, the sterilization judgment unit 84, the non-sterilization notification unit 85, the deadline extraction unit 86, the date acquisition unit 87, the deadline judgment unit 88, the expiration notification unit 89, and the post-sterilization judgment unit 90 are executable by the processor 60b.

[0045] In this embodiment, the memory unit 61 realized by the memory 60a pre-stores an instrument set master table TB10 (see Figure 4), a shelf master table TB20 (see Figure 5), a sterilization table TB30 (see Figure 6), and a storage history table TB40 (see Figure 7).

[0046] 4, the tool set master table TB10 is a table in which tool set information 110 is stored. The tool set information 110 is information in which at least a set ID 111 and a set name 112 are associated with each other. In other words, the tool set information 110 includes at least items such as the set ID 111 and the set name 112.

[0047] Here, "associated" refers to items that are written in the same row of the table. "Associated" can be rephrased as "corresponding."

[0048] As shown in FIG. 4, the set ID 111 is a unique ID given to each tool set 8. The set ID 111 is a character string composed of numbers, alphabets, etc., and is different for each tool set 8. The set name 112 is the name of the tool set 8. The set name 112 may be arbitrarily given to the tool set 8 by, for example, an operator. In this embodiment, the set name 112 is uniquely determined from the set ID 111.

[0049] 5, shelf master table TB20 is a table in which shelf information 120 is stored. The shelf information 120 is information in which at least a shelf ID 121, a shelf name 122, a shelf number 123, a display order 124, and an update date and time 125 are associated with each other, for example. Here, the shelf information 120 includes at least items such as the shelf ID 121, the shelf name 122, the shelf number 123, the display order 124, and the update date and time 125.

[0050] The shelf ID 121 is a unique ID given to each shelf number 3 (see FIG. 1) of the shelf 2 storing the instrument set 8. The shelf ID 121 is a character string composed of numbers, letters, etc., and is different for each shelf number 3 of the shelf 2. The shelf name 122 is the name of the shelf 2. The shelf name 122 is arbitrarily given to the shelf 2 by, for example, an operator. The shelf number 123 is the shelf number given to the shelf 2, and is the shelf number 3 of the shelf 2 (see FIG. 1). In this embodiment, the shelf number 3 of the shelf 2 shown in FIG. 1, or the shelf number 3a of the post-sterilization shelf 2a, is identified from the shelf ID 121.

[0051] 1. For example, the list of shelves 2 and shelf numbers 3 is displayed in ascending or descending order of the display order 124. The update date and time 125 is the date and time when the shelf information 120 was updated. Here, when any of the items of the shelf ID 121, shelf name 122, shelf number 123, and display order 124 associated with the update date and time 125 is changed, the date and time of the change is recorded in the update date and time 125.

[0052] As shown in Fig. 6, the sterilization table TB30 is a table in which sterilization information 130 for an instrument set 8 is stored. The sterilization information 130 is information in which at least a sterilization ID 131, a set ID 132, a set name 133, a shelf ID 134, a user ID 135, a user name 136, and a sterilization expiration date 137 are associated with each other. Here, the sterilization information 130 includes at least items such as the sterilization ID 131, the set ID 132, the set name 133, the shelf ID 134, the user ID 135, the user name 136, and the sterilization expiration date 137. In this embodiment, the sterilization information 130 is an example of the storage location information and sterilization information of the present invention, and is information combining the storage location information and sterilization information of the present invention.

[0053] The sterilization ID 131 is a unique ID given to the instrument set 8 sterilized in the sterilization process 15 shown in FIG. 2. Here, the instrument set 8 given the sterilization ID 131 is determined to have been sterilized. The instrument set 8 can be identified from the sterilization ID 131. The sterilization ID 131 is an example of an identification ID of the present invention. The set ID 132 is a set ID given to the instrument set 8 given the sterilization ID 131. The set ID 132 corresponds to the set ID 111 (see FIG. 4) in the instrument set information 110. The set name 133 shown in FIG. 6 is a set name of the instrument set 8 given the sterilization ID 131. The set name 133 corresponds to the set name 112 (see FIG. 4) in the instrument set information 110. Either the set ID 132 or the set name 133 may be omitted.

[0054] The shelf ID 134 shown in FIG. 6 is an ID given to the shelf number 3 of the shelf 2 on which the instrument set 8 with the sterilization ID 131 is stored. The shelf ID 134 corresponds to the shelf ID 121 (see FIG. 5) in the shelf information 120. The user ID 135 shown in FIG. 6 is an ID of the operator who sterilized the instrument set 8 with the sterilization ID 131. The user name 136 is a name (appellation) of the operator who sterilized the instrument set 8 with the sterilization ID 131. Here, the user ID 135 and the user name 136 correspond to the user information (not shown) stored in the user master table (not shown). The user name 136 can be uniquely determined from the user ID 135. Therefore, either the user ID 135 or the user name 136 may be omitted.

[0055] The sterilization expiration date 137 is the expiration date of the sterilization process performed on the instrument set 8 to which the sterilization ID 131 is attached. The sterilization expiration date 137 is set to a date a predetermined period of time after the issuance of the sterilization label 20 (see FIG. 1). This predetermined period is set based on the type of sterilization process and the type of one or more medical instruments 5 that make up the sterilized instrument set 8.

[0056] As shown in Fig. 7, storage history table TB40 is a table in which storage history information 140, which is history information of instrument sets 8 stored in storage process 16 shown in Fig. 2, is stored. Storage history information 140 is information in which at least a storage ID 141, a shelf ID 142, a shelf name / shelf number 143, a set ID 144, a sterilization ID 145, restocking information 146, stocking date / time 147, a user ID 148, and a user name 149 are associated with each other, for example. Storage history information 140 includes at least items such as storage ID 141, shelf ID 142, shelf name / shelf number 143, set ID 144, sterilization ID 145, restocking information 146, stocking date / time 147, user ID 148, and user name 149.

[0057] The storage ID 141 is a unique ID that is assigned to the stored instrument set 8 when the instrument set 8 is stored in the storage process 16. The storage ID 141 is a character string composed of numbers, letters, etc., and is an ID that is issued every time an instrument set 8 is stored. Therefore, a different storage ID 141 is issued every time one instrument set 8 circulates through the circulation cycle 10 and is stored in the storage process 16. Therefore, multiple storage IDs 141 may be assigned to one instrument set 8.

[0058] The shelf ID 142 is the shelf ID of the shelf number 3 (see FIG. 1) of the shelf 2 where the instrument set 8 to which the storage ID 141 is assigned is stored. The shelf ID 142 corresponds to the shelf ID 121 (see FIG. 5) of the shelf information 120. The shelf name and shelf number 143 shown in FIG. 7 are the shelf name and shelf number where the instrument set 8 to which the storage ID 141 is assigned is stored. Here, the shelf name and shelf number 143 are expressed as shelf name [shelf number]. The shelf name and shelf number 143 correspond to the shelf name 122 (see FIG. 5) and shelf number 123 (see FIG. 5) of the shelf information 120. The set ID 144 shown in FIG. 7 is the set ID assigned to the instrument set 8 to which the storage ID 141 is assigned. The set ID 144 corresponds to the set ID 111 (see FIG. 4) of the instrument set information 110. 7 is a sterilization ID that was assigned when the instrument set 8 with the storage ID 141 was sterilized. The sterilization ID 145 corresponds to the sterilization ID 131 of the sterilization information 130 (see FIG. 6).

[0059] The restocking information 146 shown in FIG. 7 is information on whether the instrument set 8 with the storage ID 141 is restocked. Restocking here means that an instrument set 8 that was not used in the surgery / examination process 11 is restocked in the storage process 16 without being sterilized in the sterilization process 15. For example, if the associated instrument set 8 is not restocked but is the first time it is stocked (first stocking in this case), the restocking information 146 is set to "1". On the other hand, if the associated instrument set 8 is restocked and is the second or subsequent time it is stocked, the restocking information 146 is set to "2". However, the specific numerical values ​​and characters of the restocking information 146 can be set appropriately for each medical site, and the first stocking is not limited to "1", and the restocking is not limited to "2".

[0060] The storage date and time 147 is the date and time when the tool set 8 with the storage ID 141 is stored, that is, the date and time when the tool set 8 is stored in the shelf number 3 of the shelf 2. The user ID 148 is the ID of the worker who stored the tool set 8 with the storage ID 141. The user name 136 is the name (name) of the worker who stored the tool set 8 with the storage ID 141. Here, the user ID 148 and the user name 149 correspond to the user information (not shown) stored in the above-mentioned user master table (not shown). Since the user name 149 can be uniquely determined from the user ID 148, either the user ID 148 or the user name 149 may be omitted.

[0061] Next, the processing procedure of the storage management device 60 when the instrument set 8 is stored in the storage process 16 in FIG. 2 will be described with reference to the flowcharts in FIG. 8A and FIG. 8B.

[0062] In this embodiment, first, in step S101 in Fig. 8A, in order to register one or more tool sets 8 to be stored in the shelf number 3 of a specified shelf 2 (see Fig. 1) in the storage management device 60, the display unit 63 in Fig. 3 displays a storage registration screen DP10 on the display device 50 as shown in Fig. 9. The storage registration screen DP10 is a screen used when storing the tool sets 8 in the shelf number 3 of a specified shelf 2 in the storage process 16, and is a screen for registering the storage destination of the tool sets 8 in the storage management device 60.

[0063] After the storage registration screen DP10 is displayed on the display device 50 in this manner, in step S103 of FIG. 8A, the shelf acquisition unit 67 of FIG. 3 acquires the target shelf ID 26 (see FIG. 1) attached to the shelf number 3 of the shelf 2 to which the tool set 8 is to be stored. Here, as shown in FIG. 1, the target shelf ID 26 is read by the reading device 30. The worker holds a reading unit (not shown) of the reading device 30 over the shelf identification label 25 attached to the shelf number 3 of the shelf 2 to which the tool set 8 is to be stored when storing the tool set 8. This causes the target shelf ID 26 recorded in the shelf identification label 25 to be read by the reading device 30. This allows the shelf acquisition unit 67 to acquire the target shelf ID 26. The target shelf ID 26 acquired by the shelf acquisition unit 67 is stored in the memory unit 61.

[0064] In this embodiment, after the target shelf ID 26 is acquired, the shelf ID 121 that matches the target shelf ID 26 is extracted from the shelf master table TB20 in Fig. 5, and the shelf name 122 and shelf number 123 associated with the extracted shelf ID 121 are extracted. Then, the display unit 63 displays the extracted shelf name 122 and shelf number 123 on the inventory registration screen DP10, as shown in Fig. 9.

[0065] Next, in step S105 in FIG. 8A, the operator registers the instrument set 8 to be stored in the shelf number 3 of the shelf 2 to which the target shelf ID 26 is attached. Here, the sterilization acquisition unit 65 in FIG. 3 first acquires the target sterilization ID 22 (see FIG. 1) of the instrument set 8 to be stored. As shown in FIG. 1, the target sterilization ID 22 is read by the reading device 30. The operator holds the reading unit of the reading device 30 over the sterilization identification mark 21 of the sterilization label 20 attached to the instrument set 8 to be stored. As a result, the target sterilization ID 22 recorded in the sterilization identification mark 21 is read by the reading device 30. As a result, the sterilization acquisition unit 65 can acquire the target sterilization ID 22. The target sterilization ID 22 acquired by the sterilization acquisition unit 65 is stored in the memory unit 61.

[0066] After the sterilization acquisition unit 65 has acquired the target sterilization ID 22 in this manner, in step S107 in Fig. 8B, it is determined whether the storage destination of the instrument set 8 bearing the target sterilization ID 22 is appropriate. In this embodiment, the storage destination, i.e., which shelf 2 and which shelf number 3 the instrument set 8 will be stored in, is preset for each instrument set 8. Here, as shown in Fig. 6, the shelf ID 134 in the sterilization information 130 on the sterilization table TB30 is the ID of the shelf number 3 of the shelf 2 that is the appropriate storage destination for the instrument set 8 bearing the sterilization ID 131.

[0067] In this embodiment, the determination as to whether the storage destination of the instrument set 8 is appropriate is performed in the order of steps S1071 and S1073. First, in step S1071, the shelf extraction unit 81 in Fig. 3 extracts the shelf ID 134 associated with the sterilization ID 131 that matches the target sterilization ID 22 from the sterilization information 130 in the sterilization table TB30 shown in Fig. 6, and sets the extracted shelf ID 134 as the extracted shelf ID 134a.

[0068] Next, in step S1073 in Fig. 8B, the shelf determination unit 82 in Fig. 3 determines whether the extraction shelf ID 134a matches the target shelf ID 26 read by the reading device 30 and acquired by the shelf acquisition unit 67 in step S103. If the extraction shelf ID 134a matches the target shelf ID 26, it is determined that the storage destination of the instrument set 8 labeled with the target sterilization ID 22 is appropriate. In this case, the process proceeds to step S111.

[0069] On the other hand, if the shelf determination unit 82 determines in step S1073 that the extraction shelf ID 134a and the target shelf ID 26 do not match, it determines that the storage destination of the instrument set 8 with the target sterilization ID 22 is inappropriate and that the instrument set 8 is on the wrong shelf. In this case, the process proceeds to step S109. In step S109, the wrong shelf notification unit 83 in Fig. 3 notifies the operator of the wrong shelf. There are no particular limitations on the method of notifying the operator of the wrong shelf.

[0070] In this embodiment, the shelf mistake notification unit 83 displays a shelf mistake warning screen DP20 on the display device 50 to notify the user of a shelf mistake, as shown in FIG. 10. The shelf mistake warning screen DP20 is displayed, for example, so as to be superimposed on the inventory registration screen DP10. The shelf mistake warning screen DP20 displays a shelf mistake message M20 such as "The shelf numbers of the shelves do not match. Please check the shelf name and shelf number.", and also displays an OK button BT20. By looking at the shelf mistake message M20, the operator can know that the shelf number 3 of the shelf 2 to which the instrument set 8 with the target sterilization ID 22 read by the reading device 30 is stored is not appropriate. In addition, the shelf mistake warning screen DP20 is closed when the operator presses the OK button BT20 via the operating device 55. Note that, although the display of the shelf mistake warning screen DP20 has been given as an example of a shelf mistake notification method, the shelf mistake warning unit 83 may notify the user of a shelf mistake by, for example, emitting a warning sound such as a buzzer from a speaker (not shown).

[0071] In this embodiment, when it is determined in step S107 of FIG. 8B that the instrument set 8 with the target sterilization ID 22 is on the wrong shelf, the instrument set 8 is not added to the inventory list LS10 (see FIG. 13) described below, and the flow charts of FIGS. 8A and 8B are terminated.

[0072] In this embodiment, in step S111 in FIG. 8B, the post-sterilization determination unit 90 in FIG. 3 determines whether the instrument set 8 to which the target sterilization ID 22 is assigned is a post-sterilization instrument set 8a. As described above, the post-sterilization instrument set 8a is preset to be stored in the shelf number 3a of the post-sterilization shelf 2a. Information on the post-sterilization shelf ID 26a (see FIG. 1) assigned to the shelf number 3a of the post-sterilization shelf 2a is pre-stored in the storage unit 61 of the memory 60a. Therefore, in this embodiment, the post-sterilization determination unit 90 determines whether the shelf ID 134 (see FIG. 6) of the sterilization information 130 corresponding to the target sterilization ID 22 is the post-sterilization shelf ID 26a. Here, the shelf ID 134 corresponding to the target sterilization ID 22 is the extracted shelf ID 134a extracted by the shelf extraction unit 81 in the above-mentioned step S1071. Therefore, the post-sterilization determination unit 90 determines whether the extracted shelf ID 134a matches the post-sterilization shelf ID 26a.

[0073] Here, if the post-sterilization determination unit 90 determines that the extraction shelf ID 134a matches the post-sterilization shelf ID 26a, it determines that the storage destination of the instrument set 8 with the target sterilization ID 22 is the shelf number 3a (see FIG. 1) of the post-sterilization shelf 2a. In this case, it is determined that the instrument set 8 with the target sterilization ID 22 is the post-sterilization instrument set 8a. In this way, if the instrument set 8 with the target sterilization ID 22 is the post-sterilization instrument set 8a, the instrument set 8 to be stored is the post-sterilization instrument set 8a to be sterilized after storage, so the process proceeds to step S117 in FIG. 8B without determining whether or not sterilization has been performed in step S112 in FIG. 8B and without determining the sterilization expiration date in step S113. Note that if it is determined that the instrument set 8 with the target sterilization ID 22 is the post-sterilization instrument set 8a, a post-sterilization instrument set notification screen (not shown) including a message indicating that the instrument set is the post-sterilization instrument set 8a may be displayed on the display device 50.

[0074] On the other hand, if the post-sterilization determination unit 90 determines in step S111 that the extraction shelf ID 134a does not match the post-sterilization shelf ID 26a, it determines that the storage destination of the instrument set 8 labeled with the target sterilization ID 22 is not shelf number 3a (see FIG. 1) on the post-sterilization shelf 2a. In this case, it is determined that the instrument set 8 labeled with the target sterilization ID 22 is not the post-sterilization instrument set 8a. In this way, if the instrument set 8 labeled with the target sterilization ID 22 is not the post-sterilization instrument set 8a, sterilization has been performed before storage, so the process proceeds to step S112 in FIG. 8B.

[0075] In step S112, it is determined whether or not sterilization has been performed on the instrument set 8 labeled with the target sterilization ID 22. In this embodiment, if the instrument set 8 has been sterilized, a sterilization ID 131 matching the target sterilization ID 22 exists in the sterilization information 130 of the sterilization table TB30. Therefore, the sterilization determination unit 84 in Fig. 3 determines whether or not a sterilization ID 131 matching the target sterilization ID 22 exists in the sterilization information 130.

[0076] If it is determined that the sterilization information 130 does not contain a sterilization ID 131 that matches the target sterilization ID 22, it is determined that the instrument set 8 bearing the target sterilization ID 22 has not been sterilized. In this case, the process proceeds to step S112A. In step S112A, the non-sterilization notification unit 85 in Fig. 3 notifies the operator that the instrument is not sterilized (that the instrument has not been sterilized). There is no particular limitation on the method of notifying the operator that the instrument is not sterilized.

[0077] In this embodiment, the non-sterilization notification unit 85 displays a non-sterilization warning screen DP22 on the display device 50 to notify the user that the instrument is not sterilized, as shown in FIG. 11A. The non-sterilization warning screen DP22 is displayed, for example, so as to be superimposed on the inventory registration screen DP10. The non-sterilization warning screen DP22 displays a non-sterilization message M22 such as "This is a non-sterilized instrument set." and also displays an OK button BT22. By looking at the non-sterilization message M22, the operator can know that the instrument set 8 with the target sterilization ID 22 read by the reading device 30 has not been sterilized. The non-sterilization warning screen DP22 is closed when the operator presses the OK button BT22 via the operating device 55. Here, the display of the non-sterilization warning screen DP22 has been given as an example of a method for notifying the user that the instrument is not sterilized. However, the non-sterilization notification unit 85 may notify the user that the instrument is not sterilized by, for example, emitting a warning sound such as a buzzer from a speaker (not shown).

[0078] On the other hand, if it is determined in step S112 that a sterilization ID 131 matching the target sterilization ID 22 is present in the sterilization information 130, it is determined that the instrument set 8 bearing the target sterilization ID 22 has been sterilized. In this case, the process proceeds to step S113.

[0079] In step S113, it is determined whether the sterilization treatment performed on the instrument set 8 bearing the target sterilization ID 22 is within the sterilization expiration date. In this embodiment, as described above, when the instrument set 8 is sterilized and the sterilization label 20 (see FIG. 1) is issued, the sterilization expiration date for the sterilization treatment of the instrument set 8 is set. This sterilization expiration date is set depending on the type of sterilization treatment and the type of one or more medical instruments 5 constituting the instrument set 8. In this embodiment, as shown in FIG. 6, the expiration date of the sterilization treatment for the instrument set 8 bearing the sterilization ID 131 is set in the sterilization expiration date 137 of the sterilization information 130 on the sterilization table TB30.

[0080] In this embodiment, the determination of whether the expiration date of the sterilization process has expired is performed in the order of steps S1131, S1133, and S1135. First, in step S1131, the expiration date extraction unit 86 in FIG. 3 extracts the sterilization expiration date 137 associated with the sterilization ID 131 that matches the target sterilization ID 22 from the sterilization table TB30 in FIG. 6, and sets the extracted sterilization expiration date 137 as the extracted sterilization expiration date 137a. Next, in step S1133, the date acquisition unit 87 in FIG. 3 acquires the current date 139, which is the current date. In this embodiment, date and time information related to the current date and time is set in the storage management device 60. The date acquisition unit 87 acquires the current date 139 based on the date and time information.

[0081] Next, in step S1135, the expiration date determination unit 88 in Fig. 3 determines whether the extraction sterilization expiration date 137a is earlier than the current date 139. If the expiration date determination unit 88 determines that the extraction sterilization expiration date 137a is the same as or later than the current date 139, it determines that the expiration date of the sterilization treatment for the instrument set 8 bearing the target sterilization ID 22 has not passed. In this case, the process proceeds to step S117 in Fig. 8B.

[0082] On the other hand, if the expiration date determining unit 88 determines in step S1135 of Fig. 8B that the extraction sterilization expiration date 137a is earlier than the current date 139, the expiration date of the sterilization process for the instrument set 8 with the target sterilization ID 22 has passed, and it is determined that the sterilization expiration date has passed. In this case, the process proceeds to step S115. In step S115, the expiration notification unit 89 of Fig. 3 notifies the operator that the sterilization expiration date has passed. There is no particular limitation on the method of notifying the operator that the sterilization expiration date has passed.

[0083] In this embodiment, the expiration notification unit 89 displays a sterilization expiration warning screen DP21 on the display device 50 to notify that the sterilization expiration has occurred, as shown in FIG. 11B. The sterilization expiration warning screen DP21 is displayed, for example, so as to be superimposed on the inventory registration screen DP10. The sterilization expiration warning screen DP21 displays a sterilization expiration message M21 such as "The sterilization expiration of this instrument set has expired," and also displays an OK button BT21. By looking at the sterilization expiration message M21, the operator can know that the expiration date of the sterilization process of the instrument set 8 with the target sterilization ID 22 read by the reading device 30 has passed. In addition, the sterilization expiration warning screen DP21 is closed when the operator presses the OK button BT21 via the operating device 55. Note that, although the display of the sterilization expiration warning screen DP21 has been given as an example of a method of notifying that the sterilization expiration has occurred, the expiration notification unit 89 may notify that the sterilization expiration has occurred by, for example, emitting a warning sound such as a buzzer from a speaker (not shown).

[0084] In this embodiment, if it is determined in step S113 of Fig. 8B that the sterilization deadline has passed, the instrument set 8 with the target sterilization ID 22 is not added to the inventory list LS10, and the flow charts of Fig. 8A and 8B are terminated. If it is determined that the sterilization deadline has passed, the process returns to the sterilization step 15 of Fig. 2, where the instrument set 8 is sterilized and a new sterilization label 20 is issued. After the new sterilization label 20 has been issued, the storage step 16 is performed again.

[0085] In this embodiment, after the target sterilization ID 22 is acquired by the sterilization acquisition unit 65, in step S117 of Fig. 8B, the determination unit 69 of Fig. 3 determines whether the instrument set 8 with the target sterilization ID 22 is a restocked item. To determine whether the instrument set 8 is a restocked item, the determination unit 69 determines whether a sterilization ID 145 matching the target sterilization ID 22 exists in the storage history information 140 (see Fig. 7). Here, the determination unit 69 determines whether an ID matching the target sterilization ID 22 exists in the sterilization IDs 145 of the storage history information 140 stored in the storage history table TB40 shown in Fig. 7.

[0086] In this embodiment, if a sterilization ID 145 matching the target sterilization ID 22 exists in the storage history information 140, it means that the instrument set 8 with the target sterilization ID 22 has already been stored at least once after the sterilization process when the sterilization label 20 (see FIG. 1) of the sterilization identification tag 21 with the target sterilization ID 22 recorded was issued. In other words, it means that the instrument set 8 with the target sterilization ID 22 has been once removed, but is re-stored without being used in the surgery / examination process 11 and without being subjected to a new sterilization process. In this way, if a sterilization ID 145 matching the target sterilization ID 22 exists in the storage history information 140, the judgment unit 69 judges that the instrument set 8 with the target sterilization ID 22 has been re-stored. If it is judged that the instrument set 8 has been re-stored, the process proceeds to step S119 in FIG. 8B.

[0087] In step S119, the notification unit 71 in FIG. 3 notifies the user that the instrument set 8 with the target sterilization ID 22 is restocked. The method of notifying the user that the instrument set 8 is restocked is not particularly limited. In this embodiment, the notification unit 71 displays a restock warning screen DP30 on the display device 50 as shown in FIG. 12, which notifies the user that the instrument set 8 is restocked. The restock warning screen DP30 is displayed, for example, so as to be superimposed on the stock registration screen DP10. The restock warning screen DP30 displays a restock message M30 such as "Restocked" and an OK button BT30. By looking at the restock message M30, the operator can know that the instrument set 8 with the target sterilization ID 22 read by the reading device 30 is restocked. The operator can close the restock warning screen DP30 by pressing the OK button BT30 via the operating device 55. In this embodiment, the process proceeds to step S121 after step S119 as shown in FIG. 8B.

[0088] On the other hand, if the judgment unit 69 judges in step S117 that the sterilization ID 145 matching the target sterilization ID 22 does not exist in the storage history information 140 (see FIG. 7), this means that the instrument set 8 bearing the target sterilization ID 22 is being stored for the first time after the sterilization process when the sterilization label 20 (see FIG. 1) of the sterilization identification tag 21 in which the target sterilization ID 22 is recorded was issued (in other words, it is being stored for the first time). In other words, this means that the instrument set 8 bearing the target sterilization ID 22 was sterilized in the sterilization process 15 after being used in the surgery / examination process 11. In this way, if the sterilization ID 145 matching the target sterilization ID 22 does not exist in the storage history information 140, the judgment unit 69 judges that the instrument set 8 bearing the target sterilization ID 22 is being stored for the first time, not re-stored.

[0089] If the determination unit 69 determines that the instrument set 8 is not to be restocked, the notification unit 71 does not notify the restocking of the instrument set 8 bearing the target sterilization ID 22. That is, the restocking warning screen DP30 as shown in Fig. 12 is not displayed on the display device 50, and the process proceeds to step S121 without performing the process of step S119 in Fig. 8B.

[0090] In this embodiment, in step S121, the list addition unit 73 in Fig. 3 adds the instrument set 8 with the target sterilization ID 22 to the inventory list LS10 shown in Fig. 13. Here, the instrument set 8 with the target sterilization ID 22 is added to the inventory list LS10 regardless of whether the instrument set 8 with the target sterilization ID 22 is a re-entry or not. The inventory list LS10 is a list displayed on the inventory registration screen DP10 by the display unit 63, and is a list of the instrument sets 8 to be stored in the shelf number 3 of the shelf 2 with the target shelf ID 26 acquired via the reading device 30.

[0091] The receiving list LS10 includes items of set name 151 and re-receiving information 152. The set name 151 is the set name of the instrument set 8 to which the target sterilization ID 22 is assigned. In this embodiment, the sterilization ID 131 that matches the target sterilization ID 22 is extracted from the sterilization information 130 of the sterilization table TB30 shown in FIG. 6, and the set name 133 associated with the extracted sterilization ID 131 is extracted. This extracted set name 133 is the set name corresponding to the target sterilization ID 22. Here, when the instrument set 8 to which the target sterilization ID 22 is assigned is added to the receiving list LS10, the list adding unit 73 adds and displays the extracted set name 133 in the set name 151 item of the receiving list LS10 displayed on the receiving registration screen DP10.

[0092] In this embodiment, the restocking information 152 of the receiving list LS10 is an item indicating whether the instrument set 8 added to the receiving list LS10 is restocked or not. For example, if the instrument set 8 added to the receiving list LS10 is restocked, the list adding unit 73 checks the restocking information 152 to add the fact that the instrument set 8 is restocked to the receiving list LS10. In this embodiment, if a sterilization ID 145 matching the target sterilization ID 22 exists in the storage history information 140 (see FIG. 7) and it is determined that the instrument set 8 with the target sterilization ID 22 is restocked, the restocking information 152 is checked. The process of checking the restocking information 152 may be performed by the notification unit 71.

[0093] In this embodiment, the receiving list LS10 is provided with a delete button BT11 corresponding to each row of the receiving list LS10. Here, when the operator presses the delete button BT11 via the operation device 55, the tool set 8 in the row corresponding to the delete button BT11 is deleted from the receiving list LS10.

[0094] In this embodiment, when multiple instrument sets 8 are stored in the shelf number 3 of the shelf 2 assigned to the target shelf ID 26, the target sterilization IDs 22 assigned to the multiple instrument sets 8 can be successively read by the reading device 30. In this case, the processes of steps S105 to S121 in Fig. 8A and Fig. 8B are executed in order every time the target sterilization ID 22 assigned to the multiple instrument sets 8 is read by the reading device 30. Then, every time the target sterilization ID 22 is read by the reading device 30 and acquired by the sterilization acquisition unit 65, the instrument set 8 assigned with the target sterilization ID 22 is added to the storage list LS10.

[0095] Here, after adding all of the tool sets 8 to be stored in the shelf number 3 of the shelf 2 assigned to the target shelf ID 26 to the storage list LS10, the worker presses the end button BT10 displayed on the storage registration screen DP10 via the operation device 55 as shown in Fig. 13. When the end button BT10 is pressed, it is confirmed that the tool sets 8 added to the storage list LS10 have been stored in the shelf number 3 of the shelf 2 assigned to the target shelf ID 26. Here, the storage history information 140 regarding the tool sets 8 added to the storage list LS10 is added to the storage history table TB40 shown in Fig. 7, so that it is confirmed that the tool set 8 has been stored in the shelf number 3 of the shelf 2 assigned to the target shelf ID 26.

[0096] When the end button BT10 is pressed, the history adding unit 75 in Fig. 3 adds storage history information 140 for each instrument set 8 added to the receiving list LS10 to the storage history table TB40. Here, the history adding unit 75 automatically issues a unique storage ID 141 for each instrument set 8 in the receiving list LS10. The history adding unit 75 adds the target shelf ID 26 to the shelf ID 142. The history adding unit 75 extracts the shelf name 122 and shelf number 123 associated with the target shelf ID 26 from the shelf information 120 (see Fig. 5) in the shelf master table TB20, and adds the extracted shelf name 122 and shelf number 123 to the shelf name / shelf number 143. The history adding unit 75 extracts the set ID 132 associated with the target sterilization ID 22 from the sterilization information 130 (see Fig. 6) in the sterilization table TB30, and adds the extracted set ID 132 to the set ID 144 of the storage history information 140.

[0097] The history adding unit 75 adds the target sterilization ID 22 to the sterilization ID 145. Information as to whether the instrument set 8 with the target sterilization ID 22 has been restocked is added to the restocking information 146. For example, if the restocking information 152 item is not checked in the stocking list LS10, the history adding unit 75 assumes that this is the first stocking and adds "1" to the restocking information 146. On the other hand, if the restocking information 152 item is checked in the stocking list LS10, the history adding unit 75 assumes that this is a restocking, in other words, the second or more times that the instrument set 8 has been restocked, and adds "2" to the restocking information 146.

[0098] The history adding unit 75 adds the date and time when the end button BT10 is pressed to the storage date and time 147. The history adding unit 75 adds the user ID and user name of the worker who stored the tool set 8 to the user ID 148 and user name 149, respectively. In this embodiment, when the storage registration screen DP10 is displayed on the display device 50, the user ID of the worker is input. The user ID input by the worker at this time is added to the user ID 148 of the storage history information 140, and the user name corresponding to the user ID input by the worker is added to the user name 149 of the storage history information 140.

[0099] As described above, after adding the storage history information 140 regarding the tool set 8 added to the receiving list LS10 to the storage history table TB40 shown in Fig. 7, the worker receives, i.e., stores, the tool set 8 added to the receiving list LS10 in the shelf number 3 of the shelf 2 to which the target shelf ID 26 is assigned. In this way, the receiving of the tool set 8 in the storage process 16 is completed.

[0100] As described above, in this embodiment, as shown in FIG. 3, the storage management device 60 for the medical instruments 5 includes a memory 60a and at least one processor 60b. The memory 60a stores sterilization information 130 (see FIG. 6), which is an example of storage destination information of the present invention. The sterilization information 130 is information in which at least a sterilization ID 131, which is an example of an identification ID for identifying the instrument set 8, and a shelf ID 134 assigned to the shelf number 3 of the shelf 2 storing the instrument set 8 are associated with each other. The at least one processor 60b is configured to be able to execute shelf acquisition processing, instrument acquisition processing, shelf extraction processing, shelf determination processing, and wrong shelf notification processing. The shelf acquisition processing is executed by the shelf acquisition unit 67 in FIG. 3. In the shelf acquisition processing, as in step S103 in FIG. 8A, the target shelf ID 26 assigned to the shelf number 3 of the shelf 2 where the instrument set 8 is to be stored is acquired. The instrument acquisition processing is executed by the sterilization acquisition unit 65 in FIG. 3. In the instrument acquisition process, as in step S105 of FIG. 8A, a target sterilization ID 22, which is an example of a target identification ID for identifying an instrument set 8 to be stored, is acquired. The shelf extraction process is executed by the shelf extraction unit 81 of FIG. 3. In the shelf extraction process, as in step S1071 of FIG. 8B, a shelf ID 134 associated with a sterilization ID 131 that matches the target sterilization ID 22, which is an example of a target identification ID, is extracted from the sterilization information 130 (see FIG. 6) and set as an extracted shelf ID 134a. The shelf determination process is executed by the shelf determination unit 82 of FIG. 3. In the shelf determination process, as in step S1073 of FIG. 8B, it is determined whether or not the extracted shelf ID 134a matches the target shelf ID 26. The wrong shelf notification process is executed by the wrong shelf notification unit 83 of FIG. 3. In the wrong shelf notification process, when the shelf determination process determines that the extraction shelf ID 134a and the target shelf ID 26 do not match, as in step S109 of Figure 8B, a wrong shelf for the instrument set 8 identified from the target sterilization ID 22 is notified.

[0101] In this embodiment, as shown in Fig. 6, in the sterilization information 130, the shelf ID 134 assigned to the shelf number 3 of the shelf 2 that is the appropriate storage destination for the instrument set 8 identified from the sterilization ID 131 is associated with the sterilization ID 131. Here, when storing the instrument set 8 in the storage process 16 of Fig. 2, the shelf ID 134 corresponding to the target sterilization ID 22 of the instrument set 8 that the operator is going to store is extracted from the sterilization information 130 as in step S1071 of Fig. 8B, and is set as the extraction shelf ID 134a. Then, as in step S1073, it is determined whether the target shelf ID 26 assigned to the shelf number 3 of the shelf 2 where the operator is going to store the instrument set 8 matches the extraction shelf ID 134a. Here, if the target shelf ID 26 does not match the extraction shelf ID 134a, it is determined that the shelf number 3 of the shelf 2 where the operator is going to store the instrument set 8 is not appropriate, and a notice of a shelf error is issued as in step S109. By being notified of the shelf mistake, the worker can notice the shelf mistake before actually storing the tool set 8. Therefore, it is possible to prevent the worker from misplacing the tool set 8 in the storage location in advance.

[0102] In this embodiment, the shelf mistake notification process executed by the shelf mistake notification unit 83 displays on the display device 50 a shelf mistake warning screen DP20 (see FIG. 10) including a shelf mistake message M20 indicating that the instrument set 8 identified from the target sterilization ID 22 is on a wrong shelf. This allows the operator to know in advance that the shelf number 3 of the shelf 2 on which the instrument set 8 bearing the target sterilization ID 22 is to be stored is wrong, by looking at the shelf mistake warning screen DP20 displayed on the display device 50 as shown in FIG. 10. This makes it easy for the operator to visually understand that the instrument set 8 bearing the target sterilization ID 22 is on a wrong shelf.

[0103] In this embodiment, as shown in FIG. 6, the sterilization information 130 is associated with at least a sterilization ID 131 indicating that the instrument set 8 has been sterilized, and a sterilization expiration date 137 of the sterilization performed on the instrument set 8. At least one processor 60b (see FIG. 3) is configured to be able to execute an instrument acquisition process, an expiration date extraction process, a date acquisition process, an expiration date determination process, and an expiration date notification process. In the instrument acquisition process executed by the sterilization acquisition unit 65 in FIG. 3, the target sterilization ID 22 attached to the instrument set 8 is acquired as in step S105 in FIG. 8A. The expiration date extraction process is executed by the expiration date extraction unit 86 in FIG. 3. In the expiration date extraction process, as in step S1131 in FIG. 8B, the sterilization expiration date 137 associated with the sterilization ID 131 that matches the target sterilization ID 22 is extracted from the sterilization information 130 (see FIG. 6) and set as the extracted sterilization expiration date 137a. The date acquisition process is executed by the date acquisition unit 87 in FIG. 3. In the date acquisition process, the current date 139 is acquired as shown in step S1133 of Fig. 8B. The deadline determination process is executed by the deadline determination unit 88 of Fig. 3. In the deadline determination process, it is determined whether the extraction sterilization expiration date 137a is earlier than the current date 139 as shown in step S1135 of Fig. 8B. The expiration notification process is executed by the expiration notification unit 89 of Fig. 3. In the expiration notification process, when it is determined in the deadline determination process that the extraction sterilization expiration date 137a is earlier than the current date 139 as shown in step S115 of Fig. 8B, the expiration notification process notifies the user that the sterilization expiration date of the instrument set 8 bearing the target sterilization ID 22 has expired.

[0104] In this embodiment, as shown in FIG. 6, the sterilization information 130 associates the sterilization expiration date 137 of the sterilization treatment for the instrument set 8 to which the sterilization ID 131 is attached with the sterilization ID 131. Here, when the instrument set 8 is stored in the storage step 16 in FIG. 2, the sterilization expiration date 137 corresponding to the target sterilization ID 22 of the instrument set 8 that the operator is about to store is extracted from the sterilization information 130 (see FIG. 6) as step S1131 in FIG. 8B, and is set as the extracted sterilization expiration date 137a. If the extracted sterilization expiration date 137a is earlier than the current date 139, it is determined that the sterilization treatment of the instrument set 8 that the operator is about to store has expired, and the sterilization expiration is notified to the operator as in step S115 in FIG. 8B. By being notified of the sterilization expiration, the operator can realize that the sterilization treatment has expired before actually storing the instrument set 8. This makes it possible to prevent the operator from storing the instrument set 8 whose sterilization treatment has expired.

[0105] In this embodiment, the expiration notification process executed by the expiration notification unit 89 in Fig. 3 displays on the display device 50 a sterilization expiration warning screen DP21 (see Fig. 11B) containing a sterilization expiration message M21 indicating that the sterilization expiration date of the instrument set 8 bearing the target sterilization ID 22 has expired. This allows the operator to know in advance that the sterilization expiration date of the instrument set 8 bearing the target sterilization ID 22 has expired by looking at the sterilization expiration warning screen DP21 displayed on the display device 50 as shown in Fig. 11B. This makes it easy for the operator to visually understand that the sterilization expiration date of the instrument set 8 bearing the target sterilization ID 22 has expired.

[0106] In this embodiment, the storage destination information of the present invention is included in sterilization information 130 (see FIG. 6). The identification ID of the present invention is the same as sterilization ID 131 in FIG. 6 and is realized by sterilization ID 131. The target identification ID of the present invention is the same as target sterilization ID 22 in FIG. 1 and is realized by target sterilization ID 22. As a result, by executing the process of obtaining target sterilization ID 22 in step S105 of FIG. 8A once, it is possible to successively execute the shelf determination process in step S1073 of FIG. 8B, the wrong shelf notification process in step S109, the expiration determination process in step S1135, and the expiration notification process in step S115.

[0107] In this embodiment, as shown in Fig. 1, the instrument set 8 includes a post-sterilization instrument set 8a that is sterilized after being removed from the storage location. The ID assigned to the shelf number 3a of the post-sterilization shelf 2a where the post-sterilization instrument set 8a is stored is set as a post-sterilization shelf ID 26a. At least one processor 60b of the storage management device 60 is configured to be able to execute a post-sterilization determination process. The post-sterilization determination process is executed by the post-sterilization determination unit 90 of Fig. 3. In the post-sterilization determination process, as in step S111 of Fig. 8B, it is determined whether or not the extraction shelf ID 134a matches the post-sterilization shelf ID 26a. When the post-sterilization determination process determines that the extraction shelf ID 134a matches the post-sterilization shelf ID 26a, the sterilization determination process, non-sterilization notification process, expiration date extraction process, date acquisition process, expiration date determination process, and expiration date notification process are not executed, i.e., steps S112, S112A, S1131, S1133, S1135, and S115 in Fig. 8B are not executed. Since the post-sterilization instrument set 8a is sterilized after storage and before surgery or examination, there is no sterilization expiration date at the time of storage. Therefore, when the post-sterilization instrument set 8a is stored, steps S112, S112A, S1131, S1133, S1135, and S115 in Fig. 8B are omitted, and processing can be performed efficiently.

[0108] In this embodiment, at least one processor 60b (see FIG. 3) is configured to be able to execute a sterilization judgment process and a non-sterilization notification process. The sterilization judgment process is executed by the sterilization judgment unit 84 of FIG. 3. In the sterilization judgment process, as in step S112 of FIG. 8B, it is determined whether or not a sterilization ID 131 that matches the target sterilization ID 22 exists in the sterilization information 130 (see FIG. 6). The non-sterilization notification process is executed by the non-sterilization notification unit 85 of FIG. 3. In the non-sterilization notification process, as in step S112A of FIG. 8B, when it is determined in the sterilization judgment process that a sterilization ID 131 that matches the target sterilization ID 22 does not exist in the sterilization information 130, a notification is issued that the instrument set 8 with the target sterilization ID 22 has not been sterilized. In this way, by being notified that the instrument set 8 has not been sterilized, the operator can realize that the instrument set 8 has not been sterilized before actually storing it. This makes it possible to prevent the operator from storing the instrument set 8 that has not been sterilized.

[0109] In this embodiment, the non-sterilization notification process executed by the non-sterilization notification unit 85 in Fig. 3 displays on the display device 50 a non-sterilization warning screen DP22 (see Fig. 11A) containing a non-sterilization message M22 indicating that the instrument set 8 bearing the target sterilization ID 22 has not been sterilized. This allows the operator to know in advance that the instrument set 8 bearing the target sterilization ID 22 has not been sterilized by looking at the non-sterilization warning screen DP22 displayed on the display device 50 as shown in Fig. 11A. This makes it easy for the operator to visually understand that the instrument set 8 bearing the target sterilization ID 22 has not been sterilized.

[0110] In this embodiment, as shown in FIG. 1, the storage management system 100 includes a storage management device 60 for medical instruments 5, a display device 50, an operation device 55, and a reading device 30. The instrument set 8 is provided with a sterilization identification label 21 in which a target sterilization ID 22, which is an example of a target identification ID, is recorded. The shelf number 3 of the shelf 2 storing the instrument set 8 is provided with a shelf identification label 25 in which a target shelf ID 26 is recorded. The reading device 30 is operated by an operator and can read the sterilization identification label 21 and the shelf identification label 25. In the shelf acquisition process performed by the shelf acquisition unit 67 in FIG. 3, the shelf identification label 25 is read by the reading device 30 to acquire the target shelf ID 26. In the instrument acquisition process performed by the sterilization acquisition unit 65 in FIG. 3, the sterilization identification label 21 is read by the reading device 30 to acquire the target sterilization ID 22. This allows the storage management device 60 to obtain the target sterilization ID 22 by the simple method of the worker reading the sterilization identification label 21 of the instrument set 8 to be stored with the reading device 30. Also, the storage management device 60 can obtain the target shelf ID 26 by the simple method of the worker reading with the reading device 30 the shelf identification label 25 attached to the shelf number 3 of the shelf 2 where the instrument set 8 is to be stored.

[0111] In this embodiment, as shown in Fig. 8B, step S107, which is a process for determining whether the instrument is on the wrong shelf, step S111, which is a process for determining whether the instrument is a post-sterilization instrument set 8a, step S112, which is a process for determining whether the instrument has been sterilized (in other words, whether the instrument is non-sterilized), step S113, which is a process for determining whether the sterilization expiration date has passed, and step S117, which is a process for determining whether the instrument has been restocked, are executed in this order. However, the order in which steps S107, S111, S112, S113, and S117 are executed is not particularly limited, and the order of the processes may be changed as appropriate. For example, the processes may be executed in the order of steps S111, S112, S113, S107, and S117.

[0112] In this embodiment, the identification ID of the present invention is the sterilization ID 131 of the sterilization information 130. However, the identification ID of the present invention may be a set ID 132 capable of identifying the instrument set 8. In this case, the object identification ID of the present invention may be an object set ID attached to the instrument set 8.

[0113] In this embodiment, the storage location information and sterilization information of the present invention are realized by sterilization information 130 and are stored in sterilization table TB30. However, the storage location information and sterilization information of the present invention may be separate information and stored in separate tables. [Explanation of symbols]
