Description

The present invention relates to a medical device set management system.

Japanese Unexamined Patent Publication No. 2019-24609 discloses a management system for a medical device set. The publication proposes a system that facilitates the distribution of instruments constituting a medical device set, in particular, in the cleaning process.

Japanese Unexamined Patent Publication No. 2019-24609

Medical instruments are generally controlled in the order of, for example, a surgical process, a recovery process, a cleaning process, an assembly process, a sterilization process, and a storage process. After being collected, the medical device set is sorted by cleaning method and sent to the cleaning process. Next, in the assembly process, the medical devices are sorted by the medical device set, the medical devices are appropriately assembled, and the medical devices are packaged in a predetermined packaging form. In the sterilization step, each medical device set is sterilized by a predetermined sterilization method. After the sterilization process, it is determined whether or not sterilization has been properly performed through an indicator for each medical device set. If properly sterilized, it will be stored in a designated storage location until the next use. Then, the instruments stored after sterilization are used again in surgery and medical treatment.

Hospitals and the like own and use multiple types of medical devices and sets of medical devices. Further, in a large hospital having a plurality of clinical departments, a plurality of medical device sets are owned for each clinical department, but the facilities may be shared from the cleaning process to the sterilization process. Thus, in one hospital, there are many medical devices or sets of medical devices of the same type. Management is cumbersome when there are many medical devices or medical device sets of the same type. In particular, the cleaning method, packaging method, and sterilization method are predetermined for each device or medical device set.

The present inventor wants to realize that the warranty period of sterilization is properly managed for such a medical device or a medical device set.

The medical device set management system disclosed herein includes at least one storage device and at least one arithmetic unit that cooperates with the storage device. The system stores the device ID associated with the medical device on a one-to-one basis. The system stores a set ID that is one-to-one associated with a medical device set composed of a plurality of medical devices. The system stores the sterilization warranty period set for the medical device or medical device set in association with the writing device ID or set ID. The system remembers when the packaging operation was performed on the medical device or medical device set in association with the device ID or the set ID. The system obtains a sterilization warranty period based on when the packaging work is performed on the medical device or medical device set and the sterilization warranty period. The system is configured to extract an instrument ID or set ID under predetermined conditions based on the sterilization warranty period.

According to such a medical device set management system, the sterilization guarantee period is obtained based on the time when the packaging work is performed on the medical device or the medical device set and the sterilization guarantee period. The sterilization guarantee period is based on the time when the packaging work is performed, and the sterilization guarantee period is set to a time with a margin in terms of safety as compared with the time when the sterilization work is performed. Therefore, the sterilization guarantee period is more reliably managed on the safe side.

Hereinafter, a medical device set management system according to an embodiment of the present invention will be described with reference to the drawings. It should be noted that the embodiments described here are, of course, not intended to limit the present invention.

Here, a medical device set is a group of medical devices used in one operation, one step of surgery, or a medical examination. The medical device set is packaged in one bag or container, sterilized, and stored as one group. Such a medical device set is appropriately referred to as a "surgery set" or a "medical examination set". Here, medical devices are appropriately referred to as devices.

Instruments included in the medical device set include, for example, tracals, forceps, incision devices, cleaning and suction devices, shear blades (coopers), scalpels, scalpel holders, cannulas, syringes, syringes, scales, sondes, eleva, raspa, suction. Tubes, chest openers, chest closures, needle holders, syringes, metal balls, pus basins, cups, pins, mirrors, razors, mouth openers, scalpels, handpieces, fleas, sharpeners, strippers, mirrors, suture needles , Stanze, water receiver, needle, indenter, bougie, vent tube, bone fragment driving device, rewell, radio pliers, hammer, tweezers, dropper, enema, syringe, etc.

Medical devices include devices that are composed of a plurality of components. For example, a tracal, forceps, an incision device, a lavage suction device, and the like used in laparoscopic surgery are composed of a plurality of components, are collected after the operation, and are disassembled into a plurality of components. Here, the parts that make up a medical device are called component parts. Further, the component may be further composed of a plurality of components, and in such a case, all of them are referred to as components.

Cleaning work is determined for each of such a medical device and a component of the medical device. Therefore, the medical device and the component parts of the device are collected after the operation, sorted for each designated cleaning operation, and sent to the cleaning process. After cleaning, an instrument composed of a plurality of components is assembled, and is placed in a predetermined container and sealed for each medical device set or for each medical device. It is then sterilized by the specified sterilization method and stored until the next use. In this way, in the use of the medical device set, the steps of surgery (medical treatment) → collection (sorting) → cleaning → assembly (packaging) → sterilization → storage → surgery are repeated. In the assembly process, the work is performed from assembly to packaging (sealing). Therefore, the assembly process can also be appropriately referred to as a packaging process or a sealing process. It is important to ensure that each device and component of the medical device set is cleaned by an appropriate method and procedure in order to prevent nosocomial infections.

By the way, since medical device sets and medical devices go through the processes of collection, cleaning, assembly, packaging (sealing), sterilization, and storage after surgery, many hospitals use many types of medical device sets and devices. I have more than one of each, and I take out and use the stored medical equipment sets and equipment. In such a case, management becomes complicated. For example, even with the same type of medical device set or medical device, the frequency of use varies. In addition, it is difficult to determine how effectively a medical device set or medical device is being used. Also, even if there is a medical device set or medical device that is not used at all for a certain period of time, no one may notice it.

The medical device set management system disclosed herein can be used, for example, to properly manage the medical device set and the device.

FIG. 1 is a schematic diagram of a medical device set management system 10 (hereinafter, appropriately referred to as “system 10” in the present specification). In the form shown in FIG. 1, the system 10 includes a processing device 100 and a storage device 120 as a hardware configuration. Further, the system 10 includes a reader 11, a display device 12, a printing machine 13, and an operation terminal 14.

The reader 11 is a device that reads the device of the medical device set, the individual information incorporated in the component of the device, or the individual information attached to the bag or container that houses the device or the medical device set.

Individual information may be individually assigned so that the device or component can be identified. Here, the individual information can be a two-dimensional symbol of a predetermined form. For example, the individual information used for the device of the medical device set can be embodied by a two-dimensional bar code, a non-contact tag such as RFID, or a two-dimensional symbol such as an engraving formed on the surface of the device. Further, the engraving can be formed by laser engraving or engraving.

For the formation of the two-dimensional symbol by engraving, for example, a metal printer (for example, MPX-95 manufactured by Roland DG Co., Ltd.) can be used. According to such a metal printer, it is possible to form a data matrix with a fine size of, for example, about 1 mm to 4 mm square. The two-dimensional symbol by engraving is formed by denting the surface of the instrument. The plating film on the surface of the device is not easily scratched, and the two-dimensional symbol makes it difficult for the device to rust. In addition, with the development of metal printers and the like, it can be applied to existing appliances in which a two-dimensional symbol is not formed, and a two-dimensional symbol can be set and given by a user.

In assembly, sterilization or storage, for example, instruments that do not belong to the medical device set are appropriately individually wrapped. In addition, the medical device set is in a state of being collectively housed in a bag or a container. In this case, it is preferable that individual information such as a two-dimensional symbol is attached to the bag or container that houses the device or medical device set.

The reader 11 is a reading device that reads information. The reader 11 may include, for example, a detection unit for detecting individual information. For example, as a detection unit for detecting a two-dimensional symbol, a camera, a CCD image sensor, or the like can be mentioned. The detection unit of the reader 11 may be configured so that the individual information attached to an instrument, a component, a bag, or the like is directed so that the individual information can be read. Specifically, the reader 11 may have a function of replacing the information read from the individual information with the information that can be processed by the computer. The reader 11 may be configured so that its function is embodied in collaboration with the operation terminal 14.

The display device 12 is a device that functions as one of the output devices of the system 10. The display device 12 is a device that displays image, moving image, and character information. Further, as the display device 12, a device having a touch panel function can be used. In this case, the display device 12 can function as an input device for the system 10. The display device 12 may be a display attached to the operation terminal 14. For example, when the operation terminal 14 is a mobile terminal such as a tablet computer or a smartphone, the display can function as the display device 12.

The printing machine 13 is a device that functions as one of the output devices of the system 10. It is operated according to the instruction of the system 10 to print a predetermined printed matter. For example, a label attached to a medical device set, a medical device, or a packaging material thereof may be printed.

The operation terminal 14 is a terminal for operating various processes of the system 10. Further, the operation terminal 14 is provided with a processing device and a storage device, and may have a function of executing a part of the processing of the system 10.

The processing device 100 and the storage device 120 are illustrated as the processing device and storage device of the server 20 in FIG. The processing device 100 executes processing necessary for the system 10 to function. The storage device 120 stores information necessary for the system 10 to function. Information is appropriately written in the storage device 120 through the processing device 100, and the information written in the storage device is appropriately taken out through the processing device 100. The server 20 and the operation terminal 14 may be connected to each other through the communication network 15. The operation terminal 14 can function as a client computer of the system 10 in cooperation with the server 20. The operating terminal 14 can also function as part of the processing or storage device of the system 10.

Here, the processing device 100 is a device that processes a signal on a computer according to a predetermined program. The processing device 100 is also referred to as a processor, a CPU (Central Processing Unit), an MPU (Micro-processing unit), or the like. The storage device 120 is a device that stores information processed on a computer. The storage device 120 is referred to as a memory, a hard disk, or the like. Each function of the system 10 is embodied by processing in collaboration with the processing device 100, the storage device 120, and software. The software may be stored, for example, in a portion of the storage device 120 and may be incorporated into the system 10 so that it may be appropriately executed by the processing device 100. For example, each function of the system 10 can be embodied as a processing module that performs predetermined arithmetic processing, as data, or as a part thereof. Specifically, each processing module is a program. Information is input to the system 10 through the reader 11 and the operation terminal 14. Further, the system 10 outputs a predetermined output through the operation terminal 14.

The system 10 is not limited to the form shown in FIG. For example, the system 10 may include at least one processing device 100 and a storage device 120 as the entire system. The system 10 may be connected to a plurality of readers 11, a display device 12, a printing machine 13, and an operation terminal 14, respectively. Further, the system 10 may be connected to a reader 11, a display device 12, a printing machine 13, and an operation terminal 14 which are remote via a network 15.

FIG. 2 is a schematic view showing an application example of the system 10. In this system 10, for example, as shown in FIG. 2, in each process (each work area) of surgery → collection (sorting) → cleaning → assembly (sealing) → sterilization → storage → surgery, instruments or medical treatment The work history of the instrument set is recorded as appropriate. The display device 12, the printing machine 13, and the operation terminal 14 may be arranged in the work area as shown in FIG. In the form shown in FIG. 2, the operation terminals 14a to 14f and the readers 11a to 11f are placed in the operation areas A1, the collection area A2, the cleaning area A3, the assembly area A4, the sterilization area A5, and the storage area A6. The state in which is placed is shown.

The surgery area A1 is an area where medical devices and medical device sets are used by medical professionals such as doctors and nurses, and is an area where surgery and medical examinations are performed.
The collection area A2 is an area where the medical device set and the medical device are collected from the operation area A1. Here, the medical device set can be collected separately for each medical device.
The cleaning area A3 is an area for cleaning the medical device set and the medical device. Here, the medical device can be disassembled and cleaned for each part.
The assembly area A4 is an area for assembling a washed medical device set and medical device and packaging them in a predetermined container or bag.
The sterilization area A5 is an area for sterilizing the medical device set and the medical device. Medical device sets and medical devices are sterilized in a given container or bag.
The storage area A6 is an area for storing a sterilized medical device set and medical devices.

In this embodiment, the operation area A1, the collection area A2, the cleaning area A3, the assembly area A4, the sterilization area A5, and the storage area A6 are classified, but the present invention is not limited to such an embodiment. For example, medical device sets and medical devices may be sent for repair or maintenance. In such a case, the concept of a maintenance area may be provided, and the medical device set and the medical device may be divided into the areas when they are sent for repair or maintenance. In addition, cleaning, assembly, and sterilization work may be performed by a specialized contractor different from surgery. In such a case, the cleaning area A3, the assembly area A4, and the sterilization area A5 may be provided in a facility different from the operation area A1, the collection area A2, the storage area A6, and the like. The operation area A1, the collection area A2, and the storage area A6 can also be provided at different locations. Further, in this system 10, it is possible to collectively manage medical device sets and devices used in a plurality of hospitals. In such a case, the operation area A1 and the collection area A2 may be installed at a plurality of places.

In the system 10, the operation terminals 14g may be connected separately from the operation terminals 14a to 14f arranged in each work area. The operation terminal 14g is a so-called mobile terminal that can be carried, and is not limited depending on the location. The operation terminal 14g appropriately functions as an operation terminal of the system 10. The operation terminal 14g can be used in a place different from the work areas A1 to A6, such as a maintenance area.

The display devices 12a to 12g attached to the operation terminals 14a to 14g each function as display devices of the system 10. As shown in FIG. 2, the system 10 may include a server 20 that functions in cooperation with the operating terminals 14a to 14g. The server 20 may include a processing device 100 and a storage device 120, which are the cores for embodying the functions of the system 10. In this specification, the reference numerals are distinguished from the readers 11a to 11f, the display devices 12a to 12g, the operation terminals 14a to 14g, and the like according to each work area. The readers 11a to 11f, the display devices 12a to 12g, and the operation terminals 14a to 14g are simply referred to as "reader 11", "display device 12", and "operation terminal 14" when it is not necessary to distinguish them. Further, the printing machine 13 may be arranged in the assembly area A4, for example.

Each of the above-mentioned areas A1 to A6 can be defined as a place where a predetermined work is performed. However, on the system, it is preferable that the identification ID is assigned to each area A1 to A6 and stored in the master data. On the system, the readers 11a to 11f and the operation terminals 14a to 14f arranged in the areas A1 to A6 may be associated with the areas A1 to A6. For example, the information input by the readers 11a to 11f and the operation terminals 14a to 14f may be handled by the system 10 as the information input in each of the areas A1 to A6. In the present specification, "master data" refers to basic information common to this system. Multiple master data are prepared for each target.

Further, the actual locations of the areas A1 to A6 may overlap. For example, when the collection is performed at the same place where the surgery or medical treatment is performed, the places of the surgery area A1 and the collection area A2 may overlap. Further, the reader 11, the display device 12, and the operation terminal 14 may be common to the operation area A1 and the collection area A2. In this case, it is preferable that the functions and settings of the operation terminal 14 are configured to be switched according to each area A1 to A6 by, for example, processing on software. For example, the operation terminal 14 may be configured so as to be appropriately switched between a function and a setting corresponding to the operation area A1 and a function and a setting according to the collection area A2 by a predetermined operation.

In FIG. 2, a reader 11, a display device 12, and an operation terminal 14 are arranged in each of the areas A1 to A6, but the reader 11, the display device 12, and the operation terminal are arranged in each of the areas A1 to A6. A plurality of 14 may be arranged respectively. Further, in each of the areas A1 to A6, the reader 11, the display device 12, and the operation terminal 14 may be shared in different areas. Note that FIGS. 1 and 2 are schematic views of the system. The system 10 is not limited to such a form. The system 10 may include more readers 11, display devices 12, and operating terminals 14. The operation terminals 14a to 14g may be embodied by a single device, or a plurality of devices may cooperate to function as a processing device. That is, in FIG. 1, the processing device 100 is shown as one device, but is not limited to one device.

The readers 11a to 11f, the operation terminals 14a to 14g, and the server 20 may be connected in both directions so that data communication is possible. In the form shown in FIG. 2, the readers 11a to 11f, the operation terminals 14a to 14g, and the server 20 are linked with each other in a state where data communication is possible through the communication network 15. The operating terminals 14a to 14g, the readers 11a to 11f, and the processing device 100 are in a state in which information communication is possible with each other by, for example, a wireless communication network constructed through a router (not shown) or a wired communication network such as a LAN cable. It is good to be connected with.

The displays 12a to 12g of the operation terminals 14a to 14g shown in FIG. 2 function as the display devices 12 shown in FIG. 1, respectively. In the form shown in FIG. 2, the operation terminals 14a to 14g and the server 20 can function as a processing device 100 and a storage device 120 (see FIG. 1) of the system 10 in appropriate cooperation. Thus, in the embodiments shown in FIGS. 1 and 2, the system 10 is embodied by a plurality of devices. In the system 10, a plurality of computers such as operation terminals 14a to 14g and a server 20 are linked. The system 10 is used in parallel by a plurality of different users at a plurality of remote locations at the same time. Many medical device sets and devices are managed in parallel in a plurality of processes.

FIG. 2 shows one application example of the system 10. The configuration of the system 10 is not limited to the form shown in FIG. For example, in the example shown in FIG. 2, the operation terminal 14 is shown as a laptop type terminal, but is not limited to the form of the terminal, and is, for example, a tablet type terminal or a stationary type terminal. May be good. Further, although the system 10 includes a core server 20, the system 10 does not have to include the server 20. For example, the system 10 may include at least one storage device and at least one processing device that cooperates with the storage device. In the form shown in FIG. 2, the system 10 is embodied by the cooperation of the server 20 and the plurality of operation terminals 14. The server 20 and the plurality of operation terminals 14 each include a storage device and a processing device. The system 10 is not limited to the form shown in FIG. For example, the system 10 may be embodied by one terminal. For example, the server 20 may be configured to perform all the functions of the system 10. Further, the system 10 may be configured such that, for example, a plurality of devices connected by a network cooperate to store and process information. In this case, even if the system 10 is configured such that the plurality of processing devices 100 and the plurality of storage devices 120 connected by a network function as the processing device 100 and the storage device 120 of the system 10 in cooperation with each other. good. The system 10 can thus be embodied as a client-server type, stand-alone type, or distributed file system type system.

It is preferable that the medical device set is given a set ID for identifying the medical device set on a one-to-one basis. It is preferable that the medical device is given a device ID for identifying the medical device on a one-to-one basis. Further, it is preferable that the medical device that is disassembled in the work such as cleaning is given a part ID for identifying the part for each part.

In the system 10, for example, the set ID may be stored in association with information about the medical device set. The device ID may be stored in association with information about the medical device. The part ID may be stored in association with information about the part.

Further, the information about the affiliation may be stored in association with the device ID or the set ID. Here, the affiliation can be defined by a clinical department such as surgery or internal medicine in the case of a hospital, for example. In addition, in the case of managing equipment and medical equipment sets of a plurality of hospitals together, the affiliation includes information such as hospitals. In this way, the affiliation may include a plurality of pieces of information in several layers. For example, in this embodiment, affiliation 1 includes information on a hospital, and affiliation 2 includes information on a clinical department. The information regarding such affiliation may be included in the information regarding the medical device set or a part of the information regarding the medical device.

In this system 10, it is preferable that the set ID, the instrument ID, the component ID, and the individual information, image data, affiliation-related information, and the like associated with these are stored in advance in a database or the like as master data. In addition, information such as a cleaning method, a packaging material, and a sterilization method may be appropriately stored in advance as master data in the system 10.

3 and 4 are diagrams showing configuration examples of master data 400 and 410 of the medical device set, respectively. In the master data 400 shown in FIG. 3, a column 401 for storing the set ID, a column 402 for storing the medical device set name, a column 403 for storing the device ID, a field 404 for storing the device name, and a component ID are stored. A column 405, a column 406 for storing a GS1 code as individual information, and a column 407 for storing an image file of a medical device set or a device or a part are provided. In the master data 410 shown in FIG. 4, the column 411 for storing the set ID1, the column 421 for storing the number of instruments of the medical device set 12, the column 413, 414 for storing the information about the affiliation, and the column 415 for storing the packaging type. Column 416 for storing the sterilization type, column 417a for storing the storage shelf, column 417b for storing the shelf number, column for storing the necessity of the out-of-sterilization alert (in this embodiment, out of sterilization 418a, 1 week 418b, 1 month). 418c), a column 419b for storing the necessity of label printing is provided.

In this way, information about the medical device set is stored in association with the set ID. Of these, the image file contains images of medical device sets, devices or components. The image file may be configured such that the image is appropriately displayed through the display devices 12a to 12g. The information input to the database 400 may be configured so that a predetermined registration screen on which information in each field can be input is prepared and the information input on the registration screen is registered as master data. ..

The data structure of the master data is not limited to the structure shown in FIGS. 3 and 4. Further, the master data registration screen is not particularly limited. The set ID, the instrument ID, the component ID, and the individual information, image data, and information related to the affiliation associated with these may be those in which a plurality of databases storing individual information are associated with each other. For example, a database that records information on a medical device set, a database that records information on medical devices, and a database that records information on parts are prepared. Each database may contain information that correlates the medical device set, the medical device, and the component. For example, it is preferable that one of the databases contains information for associating a medical device with a medical device set and information for associating a medical device with a part. This correlates the medical device set, the medical device, and the parts. Similarly, individual information, image data, information on affiliation, and the like may be individually prepared as a database so that the medical device set, the medical device, and the parts can be associated with each other. Similarly in the following, the data structure of the master data can be selected in various ways and is not particularly limited.

The packaging type specifies a packaging material and a packaging method. Here, the packaging material includes a non-woven fabric, a sterilization bag, a container, a tray, and the like. As a packaging method, it may be wrapped in a non-woven fabric, stored in a sterilization bag, or further wrapped in a non-woven fabric and stored in a sterilization bag. For example, the packaging container, the sealing method, and the like may be predetermined so as to be specified for each packaging type. The system 10 may store in advance information that identifies the packaging type of the medical device or medical device set. For example, for the packaging type, master data may be prepared in advance.

FIG. 5 is a diagram showing a configuration example of master data of the packaging type. The master data 420 shown in FIG. 5 includes a column 421 for storing the packaging type, a column 422 for storing the packaging material 1, a column 423 for storing the packaging material 2, and a column 424 for storing the packaging material 3. I have. According to the master data 420, the packaging material is configured to be identified from the packaging type. The packaging material 1 indicates, for example, an exterior material. The packaging material 2 indicates, for example, an interior material. The packaging material 3 may be added when a packaging method in which different packaging materials are used together is adopted. For example, the packaging type referred to as Pack2 is to wrap the target medical device or medical device set with a non-woven fabric and further put it in a container.

The sterilization type specifies the sterilization method. The sterilization type may be predetermined, for example, so that the sterilization method, sterilization conditions, and the like are specified for each sterilization type. The system 10 may pre-store information identifying the sterilization type of the medical device or medical device set. For example, for the sterilization type, master data may be prepared in advance. FIG. 6 is a diagram showing sterilization type master data 440. The master data 440 shown in FIG. 6 includes a column 441 for storing the sterilization type, a column 442 for storing the sterilization method, a column 443 for storing the sterilization condition 1, a column 444 for storing the sterilization condition 2, and sterilization. It is provided with a column 445 for storing the condition 3. According to such master data 440, the sterilization method and sterilization conditions are specified from the sterilization type. The sterilization type may include those for which only the sterilization method is specified.

Here, the sterilization methods include, for example, high-pressure steam sterilization (so-called autoclave), ethylene oxide gas sterilization (so-called EOG sterilization), plasma sterilization (also referred to as low-temperature plasma sterilization), dry heat sterilization, flame sterilization, and boiling sterilization. There are distribution steam sterilization, carbon dioxide gas sterilization, radiation sterilization, gamma ray sterilization, ultraviolet sterilization, formaldehyde sterilization, etc. Sterilization conditions mean the conditions adopted in these sterilization methods. For example, for temperature, time, pressure, radiation, gamma rays, ultraviolet rays, etc., it is preferable that the conditions can be set for each sterilization method such as the intensity thereof. Although the master data shown in FIG. 6 shows three conditions, it may be configured so that other conditions can be set.

As described above, the system 10 stores information for specifying the packaging type of the medical device or the medical device set in advance. Therefore, it becomes easy to specify the packaging material and the packaging method of the medical device or the medical device set on the computer. In addition, the system 10 stores information for identifying the sterilization type of the medical device or the medical device set in advance. It facilitates the process of identifying the sterilization method and sterilization conditions of medical devices and medical device sets on a computer.

The worker ID or the like is stored in advance as master data in the system 10, and may be assigned to a name tag or the like distributed to the worker. The worker ID assigned to the name tag may be readable by the reader 11b. In addition, individual information is also assigned to the readers 11a to 11f, the operation terminals 14a to 14g, and the server 20, and may be stored in advance as master data in the system 10.

Further, in the system 10, the cleaning method in the cleaning process, the more specific assembly method and packaging method in the assembly process, the more specific sterilization method in the sterilization process, and the like are also stored in association with the instrument ID or the set ID. It may have been done. Such information may be appropriately stored in advance as master data in the system 10. That is, when the instrument ID and the set ID are specified based on the master data stored in advance, the system 10 sterilizes the cleaning method in the cleaning process, the assembly method and packaging method in the assembly process, and the sterilization process. It may be configured so that information such as a method can be obtained. Although specific examples of these master data are omitted here, the data structure of the master data is not particularly limited.

In this embodiment, leaders 11a to 11f are arranged in each of the areas A1 to A6 as predetermined work spaces. Individual information is assigned to the device in the system 10. In the system 10, the individual information of the device, the device ID, and the set ID are stored in association with each other. When the individual information is detected by the readers 11a to 11f, the device ID and the set ID are specified by the individual information. It is configured to add information on the work performed on the device in association with the identified device ID to the work history of the device. Further, it is configured to add information on the work performed on the medical device set in association with the specified set ID to the work history of the medical device set.

In this system 10, when individual information is detected by the readers 11a to 11f arranged in each area A1 to A6, the instrument ID is specified by the individual information, and the work performed on the instrument in each area A1 to A6. Information is added to the work history of the equipment. Further, when the set ID is specified by the individual information, the information of the work performed on the medical device set in each of the areas A1 to A6 is added to the work history of the medical device set. In this way, since the instrument or the medical instrument set is specified via the readers 11a to 11f, the work history of the instrument or the medical instrument set can be input more reliably. For example, work information is unlikely to be entered by mistake for a device or medical device set. In the work history of the instrument or medical instrument set, for example, the time when the individual information is detected by the readers 11a to 11f is recorded in addition to the work information. In addition, information such as workers and equipment and materials used in the work may be added as appropriate.

Here, it is illustrated that when the individual information is detected, the instrument ID is specified by the individual information, and the information of the work performed on the instrument in each area A1 to A6 is added to the work history of the instrument. There is. However, unless otherwise specified, a specific means for storing the work history of the device specified by the device ID in association with the device ID, or a medical device set specified by the set ID in association with the set ID. The specific means for storing the work history is not limited to such a form. For example, in each of the areas A1 to A6, the worker may be configured to manually input the work information.

In the operation area A1, for example, when a stored instrument or medical instrument set is carried into the operation area A1, individual information is detected by the reader 11a, and the instrument ID or set ID is specified. Then, information on the date and time of delivery and the time of use are recorded in association with the device ID and set ID. Further, the work information stored in the operation area A1 may include, for example, a user (worker) such as a doctor, a patient, a medical record number of the patient, an operation or a medical treatment number, and the like. As a result, the work history of what kind of surgery the instrument or medical instrument set was used for is stored in the system 10. The amount of information that can be tracked in the work history of instruments and medical device sets increases. Further, the information of the existing electronic medical record may be incorporated into the system 10 as the work information in the operation area A1. Further, the instrument ID and the set ID may be written in the existing electronic medical record. In this way, the systems may be mutually constructed so that the existing electronic medical record and the system 10 cooperate with each other.

For example, the instruments and medical instrument sets used in the surgical area A1 are brought into the collection area A2. In the collection area A2, for example, the reader 11b detects individual information and identifies the instrument ID and the set ID. The work information stored in the collection area A2 may include, for example, information such as the date and time of collection and the worker ID.

In the collection area A2, for example, a list of instruments included in the medical device set may be displayed on the display device 12b. Then, it is preferable that the reader 11b collects the device while detecting the individual information of the device included in the medical device set. Then, it is preferable that the individual information of the device included in the medical device set is detected and the device is specified by the display device 12b. Further, when the operator specifies the device displayed on the display device 12b in the collection work, for example, the display of the device for which the individual information is detected is darkened from the list of devices included in the medical device set. You may be.

In this case, the display device 12b may be composed of, for example, a touch panel. Even if the operator touches the device to be collected from the list of displayed devices (in other words, the device specified by the individual information) on the screen of the display device 12b, the display of the device is changed. good. By such a process, the operator may be able to easily see that the device has been recovered. Then, when all the instruments included in the medical device set used in the surgical area A1 are collected in the collection area A2, the collection of the medical device set is completed. At this time, on the display device 12b, the display of the medical device set is displayed darkly, an icon indicating the end of collection is displayed, and the like, so that the operator can easily visually recognize that the device has been collected. It may be like this.

In the cleaning area A3, for example, when the reader 11c detects the individual information of the device included in the medical device set, the device ID is specified. It is preferable that the work information in the cleaning area A3 is stored in association with the specified instrument ID. The work information in the washing area A3 may include, for example, information on a washing method such as a washing machine and a detergent used for washing, and a worker ID.

Further, in this system 10, it is preferable that the instrument ID and the cleaning method are stored in association with each other in advance. In this case, when the reader 11c detects the individual information of the device included in the medical device set, the display device 12c in the cleaning area A3 performs the cleaning process required for the device based on the specified device ID. It may be configured to be displayed on the screen. Since the instrument ID is specified by the reader 11c, it is unlikely that the instrument is mistaken for cleaning processing or the instrument is mistaken for input of work information. The reader 11c may be provided in the washing machine, for example. In this case, the utensil may be put into the washing machine while reading the individual information of the utensil. In addition, information such as cleaning conditions set in the washing machine may be recorded as work information. Here, examples of the cleaning method include manual cleaning, single-layer automatic cleaning, multi-layer automatic cleaning, ultrasonic cleaning, chemical cleaning, and the like, and it is preferable that a predetermined cleaning machine or detergent is used by a predetermined method. ..

Further, the information of the existing electronic medical record may be taken in as the work information in the operation area A1. In this case, it is preferable that the cleaning method and the sterilization method of the instrument are stored in the master data in advance in association with the patient and surgery information. Based on the patient and surgery information included in the work information in the surgery area A1 and the master data, it may be constructed so as to appropriately specify the cleaning method required for the instrument. If a device or medical device set requires special cleaning based on the information in the electronic medical record, the system 10 may be constructed so that the cleaning method can be specified. Similarly, in the sterilization area A5, if a special sterilization of an instrument or medical device set is required based on the information of the electronic medical record, the system 10 may be constructed so that the sterilization method is specified. ..

In the assembly area A4, instruments are assembled from washed parts, and instruments included in a medical device set are collected and put together as a medical device set. When the equipment is assembled, necessary lubricating oil or the like is applied. At this time, for example, when the reader 11d detects the individual information of the device included in the medical device set, the device ID and the set ID of the medical device set are specified. Then, a list of instruments included in the medical device set is displayed. Further, at this time, it is preferable that the assembly work that needs to be performed in the assembly area A4 is displayed on the screen. For example, when the lubricating oil to be applied at the time of assembling the appliance is predetermined, it is preferable that the lubricating oil is displayed so as to be displayed. In the assembly area A4, the instrument or medical device set is housed in a predetermined bag or container. At that time, it is advisable to record the packaging material, packaging method, and the like.

In this system 10, as shown in FIG. 5, the master data of the packaging type is prepared. Therefore, the packaging material and the packaging method may be specified by the packaging type through the master data. Further, in the assembly area A4, when the packaging material and the packaging method are selectively registered, the packaging type recorded in the work information may be specified through the master data.

In this system 10, as shown in FIG. 3, the equipment ID and the set ID are associated with the information of the assembly method and the packaging method and stored in the master data. For example, when the reader 11d detects the individual information of the device included in the medical device set in the assembly area A4, the device ID and the set ID are specified, and further, the assembly method and the packaging method in the assembly process are specified from the master data. Information such as can be obtained. Therefore, it is difficult to perform erroneous work in the assembly method and the packaging method in the assembly process.

For example, in the assembly area A4, the medical device set may be packaged while checking that all the devices to be included in the medical device set are included. At this time, as shown in FIG. 2, a list of instruments included in the medical device set is displayed on the display device 12d, and the device is packaged while the reader 11d detects the individual information of the device when the device is packaged. It should be done. Then, it is advisable to change the display of the packaged device in the list of devices. By changing the display of the packaged appliance on the display device 12d, the operator can easily confirm the unwrapped appliance. This can prevent the device that should be included in the medical device set from being missing or accidentally entering another device into the medical device set.

The device or medical device set is, for example, packaged in a bag or container and sealed. The packaged bag or container may be accompanied by individual information for identifying the bag or container. In the assembly area A4, the individual information attached to the bag or container may be stored in association with the device ID for identifying the housed device or the set ID for specifying the medical device set. For example, in the packaging work, the reader 11d reads the individual information attached to the bag or container and the individual information of the device or medical device set to be stored in the bag or container, and reads the device or medical device set into the bag or container. To be housed in. At this time, the system 10 may store the individual information of the bag or container in association with the individual information of the stored device or medical device set. Thereby, in the post-process, the set ID of the stored medical device set and the device ID of the device can be specified based on the individual information attached to the bag or container. In addition, if the individual information attached to the bag or container and the set ID of the medical device set or the device ID of the device do not match the packaging method obtained from the master data, an alert will be issued. It may be configured in. This can prevent the medical device or medical device set from being packaged in a different way than the packaging method obtained from the master data.

In this way, in the assembly area A4, for example, the work information in the assembly area A4 is stored in association with the individual information of the bag or container read by the reader 11c. In the work information in the assembly area A4, the device ID of the device housed in the bag or container, the set ID of the medical device set, the date and time when the individual information was read by the reader 11c in the worker or the assembly work, and the worker are specified. It may include a worker ID and the like for doing so. In addition, it is preferable that the individual information of the bag or container and the individual information of the stored device or medical device set are stored in association with each other.

In the sterilization area A5, instruments and medical device sets are handled in a state of being housed in packaging materials such as bags and containers. In the sterilization area A5, for example, the reader 11e reads the individual information attached to the bag or container. Then, an instrument or a medical instrument set is specified based on the individual information. Then, a predetermined sterilization process is applied to the device or the medical device set.

In this embodiment, a database in which the sterilization process is stored in advance in association with the instrument ID and the set ID is prepared in advance. In the sterilization area A5, the reader 11e reads the individual information attached to the bag or container, and identifies the instrument ID of the instrument housed in the bag or container and the set ID of the medical device set. Then, it is preferable that the system 10 is configured so that the sterilization process in the sterilization area A5 is specified based on the instrument ID and the set ID and displayed on the display device 12e.

It is hoped that this will allow the operator to easily understand the sterilization process to be performed on the instruments and medical device sets contained in the bags and containers. Further, at this time, for example, in the sterilization area A5, it is preferable that the reader 11e is further provided in the sterilization processing machine such as an autoclave. In this case, it is preferable that the reader 11e is configured to read the individual information attached to the bag or container and then put it into the sterilization processing machine. As a result, it is preferable that the sterilization treatment is performed under predetermined sterilization treatment conditions (temperature and treatment time). Further, when the reader 11e reads the individual information attached to the bag or container, the system 10 determines that the sterilization processing machine to be loaded or the sterilization processing conditions set in the sterilization processing machine are not appropriate. May be configured to sound an alarm. in this case. By sounding the alarm, the operator's mistake is suppressed.

In the sterilization area A5, for example, the individual information attached to the bag or container is read by the reader 11d. Then, the instrument ID and the set ID are specified in association with the individual information attached to the bag or container. Then, the work information in the sterilization area A5 is stored in association with the individual information attached to the bag or container, the instrument ID, and the set ID. The work information in the sterilization area A5 may include, for example, sterilization methods and conditions for sterilization treatment. Specifically, it may further include information such as the sterilization machine used for the sterilization treatment, conditions such as sterilization temperature and treatment time, the end date and time of the sterilization treatment, and the operator.

In this system 10, as shown in FIG. 6, sterilization type master data is prepared. Therefore, the sterilization method, the conditions of the sterilization process, and the like may be specified by the sterilization type through the master data. Alternatively, in the sterilization area A5, when the sterilization method, the sterilization treatment conditions, and the like are selectively registered, the sterilization type recorded in the work information may be specified through the master data.

The storage area A6 is an area where sterilized instruments and medical instrument sets are stored. In the storage area A6, the individual information attached to the bag or container is read by the reader 11f. Then, the device ID and the set ID are specified in association with the individual information attached to the bag or container. After specifying the device ID of the housed device and the set ID of the medical device set, the bags and containers may be sorted and stored in an appropriate place. The work information recorded in the storage area A6 may include, for example, information such as a storage location for an instrument or a medical instrument set. By recording the storage location of the device or medical device set, it is easy to take out the device or medical device set.

As described above, the work information recorded by each of the areas A1 to A6 has different recorded items. The storage device 140 of the system 10 may be provided with, for example, a table in a predetermined format for storing work information of each area A1 to A6. The work information of each of the areas A1 to A6 may be stored in each field of the table prepared for each of the areas A1 to A6.

FIG. 7 is an example of the table 450 in which the work information in the collection area A2 is recorded. FIG. 8 is an example of a table 460 in which work information in the sterilization area A5 is recorded.

In the collection area A2, for example, the instruments of the medical instrument set are collected from the operation area A1 in a disjointed state. In the collection area A2, it is preferable to specify the collection place and the worker, and collect the information while reading the individual information attached to the device by the reader 11b. As a result, as in the table 450 shown in FIG. 7, information is input to each of the columns 451 to 456 regarding the set ID, the instrument ID, the part ID, the collection place, the worker, and the work date and time. The recording of work information recorded in the collection area A2 is not limited to the example of FIG. 7. The record of work information recorded in the collection area A2 may include more detailed information. Similarly, for the work information recorded in the assembly area A4, the information is input in each field such as the set ID, the instrument ID, the part ID, the packaging place, the worker, the individual information of the packaging material, and the packaging work date and time. ..

In the sterilization area A5, for example, the reader 11e reads the individual information given to the bag or container to specify the set ID of the medical device set or the device ID of the device housed in the bag or container. Then, in the sterilization area A5, the sterilization method and sterilization conditions necessary for the medical device set and the device specified by the set ID and the device ID are set in the sterilization processing machine. Then, while reading the individual information given to the bag or container with the reader 11e, it is preferable to set the medical device set or the device in the sterilization processing machine. For example, in a sterilization process, an indicator of proper sterilization may be attached to the packaging material that wraps the instrument or medical device set. In this case, the color of the indicator may change under predetermined conditions. In the sterilization area A5, indicators may be attached to instruments and medical device sets. The indicator may be attached in the assembly area A4. Also, when taken out from the sterilization processing machine, it is preferable that the individual information given to the bag or container is read by the reader 11e and the end time of the sterilization processing is recorded.

As a result, as shown in Table 460 shown in FIG. 8, the columns 461 to 469 regarding the set ID, the instrument ID, the part ID, the packaging type, the sterilization type, the sterilization guarantee period, the worker, the work date and time, and the quality of sterilization are displayed. Information is entered. The recording of work information recorded in the sterilization area A5 is not limited to the example of FIG. The recording of work information recorded in the sterilization area A5 may include more detailed information. As a record of work information in the sterilization area A5, for example, image data of an indicator after the sterilization process may be included. It is preferable that the result of the sterilization quality judgment is recorded, such as "○" for good in the sterilization quality column 469 and "x" for the defect in the sterilization quality column. The result of the quality determination of sterilization may be determined based on the determination by the indicator for each medical device set, for example. Further, the determination may be made based on the determination indicating that the sterilizer has operated normally.

Here, in the sterilization guarantee period column 466, the period during which the effect of the sterilization treatment is effective is input. The sterilization guarantee period of the sterilization process may be configured so that the sterilization guarantee period is determined by the sterilization method and the sterilization conditions. In this case, the relationship between the sterilization method, the sterilization conditions, and the sterilization guarantee period may be recorded in advance as master data of the system 10. Further, the sterilization guarantee period of the sterilization process may be configured so that the sterilization guarantee period is determined by the packaging method, the sterilization method and the sterilization conditions. In this case, the relationship between the packaging method, the sterilization method, the sterilization condition, and the sterilization guarantee period may be recorded in advance as master data of the system 10. For example, when the packaging method, the sterilization method, and the sterilization conditions are input in the sterilization area A5, the sterilization guarantee period may be input based on the master data.

In column 468 regarding the work date and time, for example, it is preferable to record the time when the individual information given to the bag or container when the sterilization process is completed and taken out from the sterilization processing machine is read by the reader 11e.

It is preferable that the processing device 100 of the system 10 is configured to collect the individual information read by the readers 11a to 11f in each of the areas A1 to A6 and the work information stored in association with the individual information. As a result, information in each area A1 to A6 of the instrument or medical instrument set managed by the system 10 is collected and centrally managed. Then, for example, work information on when and what kind of work was performed on a specific instrument in which area can be extracted in chronological order.

For example, the system 10 may be configured to store the work history of the device specified by the device ID in association with the device ID. The system 10 may be configured to store the work history of the medical device set specified by the set ID in association with the set ID. The system 10 collects work information recorded in each of the areas A1 to A6 from the operation terminals 14a to 14f. As a result, the work history of the device specified by the device ID is stored in the system 10 in association with the device ID. Further, the work history of the medical device set specified by the set ID is stored in the system 10 in association with the set ID. For example, in the form shown in FIG. 2, such information may be configured to be centrally managed by being collected and stored in the server 20.

The system 10 extracts work information based on the instrument ID from the work information stored in the processing device 100 and arranges the work information in order based on the work time, whereby the work history of the instrument specified by the instrument ID can be appropriately obtained. .. Further, by extracting the work information based on the set ID from the work information stored in the processing device 100 and arranging the work information in order based on the work time, the work history of the medical device set specified by the set ID can be appropriately obtained. ..

FIG. 9 is a diagram showing a configuration example of a data table from which the work history of a certain instrument is extracted. In the table 470 shown in FIG. 9, items 471 to 477 of the instrument ID, area (area ID), worker (user ID), work date and time, packaging method, sterilization method, and sterilization guarantee period are extracted in order and listed. Is formed. For the medical device set, the work history can be extracted in the same manner as in FIG. The extraction items of the work history are not limited to the example of FIG. The work history may include all work times recorded in each of the areas A1 to A6. The work history may not include all the work times recorded in each of the areas A1 to A6. For example, from the work information recorded in each of the areas A1 to A6, a predetermined part of the work information may be extracted.

When a plurality of instruments of the same type are managed by this system 10, the work history of a plurality of instruments of the same type can be extracted based on the type of the instrument. FIG. 10 is a diagram showing a configuration example of a data table in which work histories of a plurality of instruments of the same type are extracted based on the type of instrument. In the table 480 shown in FIG. 10, for example, when a plurality of coopers as individual medical devices not included in the medical device set are managed by the system 10, the extraction result of extracting the work history of the plurality of coopers is extracted. Is. Here, three Coopers (instrument ID: BC1, BC2, BC3) are managed by the system 10. In FIG. 10, the work histories of the three Coopers (instrument ID: BC1, BC2, BC3) are extracted. In the table 480 shown in FIG. 10, items 481 to 488 of the instrument ID, the instrument type, the area (area ID), the worker (user ID), the work date and time, the packaging type, the sterilization type, and the sterilization guarantee period are extracted in order. The list is formed.

The work history of the medical device and the medical device set should include the sterilization method and sterilization conditions of the device. In this case, it is preferable that the sterilization method, the sterilization condition, and the sterilization guarantee period are stored in association with each other. The sterilization guarantee period is also referred to as the sterilization validity period. It may be configured to provide a sterilization warranty period applied to the instrument or medical device set, at least based on the sterilization method and sterilization conditions stored.

In addition, the sterilization guarantee period may differ depending on the packaging method. In this case, the packaging method may be further considered. Here, the packaging method is defined by, for example, a packaging material and a sealing method.

In the work history of the instrument, the packaging method, the sterilization method, and the sterilization condition of the instrument may be stored. In the work history of the medical device set, the packaging method, the sterilization method, and the sterilization condition of the medical device set may be stored. The packaging method, the sterilization method, the sterilization conditions, and the sterilization guarantee period may be stored in association with each other. It may be configured to obtain the sterilization warranty period applied to the instrument or medical device set based on the stored packaging method, sterilization method and sterilization conditions. In addition to the instrument packaging method, sterilization method, and sterilization conditions, if there are items that affect the sterilization guarantee period (for example, storage method), conditions will be added appropriately in the master data, and such items will also be added. In addition, it may be configured so that a sterilization guarantee period can be obtained.

It may be configured to calculate the remaining period of the sterilization warranty period for the instrument or medical device set. For example, the sterilization guarantee period may be obtained based on the end date and time of the sterilization process, and the remaining period may be calculated. An appropriate method may be adopted as the method for calculating the remaining period of the sterilization guarantee period. It may be further configured to display the residual period calculated for each device or medical device set on the display device 12. It may also be configured to extract instruments or medical device sets based on the remaining time period. In this case, the device or medical device set extracted based on the residual period may be further configured to be displayed on the display device 12. The remaining period can also be referred to as a remaining period, a remaining period, or the like.

In this case, the calculated residual period of the sterilization guarantee period allows the operator to easily know the remaining period of the sterilization guarantee period of the instrument or the medical device set. By displaying the remaining period calculated for each device or medical device set on the display device 12, the operator can confirm the remaining period of the sterilization guarantee period of the device or medical device set on the display device 12.

The system 10 may be configured such that, for example, the remaining period of the device or medical device set is displayed on the display device 12 as a list. The system 10 may be configured to display a pie chart or a bar graph for each remaining period for the instruments and medical device sets stored in the storage area A6. Further, the system 10 may be configured to display a list of instruments and medical device sets for each remaining period. The system 10 may be configured to have a residual period of 0 and to obtain a list of so-called out-of-sterilization instruments and medical device sets. At this time, the date when the instrument or the medical device set is out of sterilization may be displayed in the list. From this, the number of days elapsed since the sterilization expired can be known. It may also be configured to provide a list of instruments and medical device sets with a residual period of less than one month. Instruments and medical device sets with a residual period of less than one month have a high priority to be used. In addition, it is preferable that the instruments and medical instrument sets that have become 0 in the remaining period and have become so-called sterilized are sterilized again. In this case, the system 10 issues a sterilization out or out of sterilization alert, counts the number of times of resterilization for each resterilized equipment, and uses a predetermined form (also referred to as a dashboard) to display devices 12a to 12g. It may be displayed in. Here, when re-sterilization is performed a plurality of times, the flow is as follows: surgery-> recovery-> cleaning-> assembly-> sterilization-> storage-> re-sterilization-> storage-> re-sterilization->. In this case, the first sterilization after assembly does not correspond to re-sterilization and is not included in the "number of re-sterilization".

For example, the system 10 may include an eleventh processing unit 211 configured to extract a resterilized instrument based on the work history of the instrument stored in the third storage unit 103. In this case, the eleventh processing unit 211 may be configured to obtain the number of times of re-sterilization of the extracted instrument.

Further, even if the system 10 includes a twelfth processing unit 212 configured to extract a resterilized medical device set based on the work history of the medical device set stored in the fourth storage unit 104. good. In this case, the twelfth processing unit 212 may be configured to obtain the number of times of re-sterilization of the extracted instrument.

Here, the process of extracting the re-sterilized instrument or medical instrument set is, for example, sterilized a plurality of times after a predetermined period without being used in the surgical area A1 based on the work history of the instrument or the medical instrument set. It may be configured to extract the device or medical device set being treated. Further, when the number of times of re-sterilization of the extracted instrument or medical device set is obtained, the device or medical device set that has been re-sterilized more than the predetermined number of times is further extracted. May be good.

This further extracts instruments and medical device sets depending on the number of resterilizations. Since the instruments and medical device sets that are re-sterilized more frequently than the predetermined number of times are extracted, the trouble of searching for the instruments and medical device sets that are frequently re-sterilized is reduced. In this case, the work information recorded in the storage area A6 may include information on the storage location of the device or medical device set. In this case, the time and effort required to take out the instruments and medical instrument sets that are frequently resterilized is further reduced. Further, for instruments and medical device sets that are only being resterilized, the number of instruments and medical device sets may be reduced. For example, the proportion of instruments or medical device sets that are only being resterilized may be calculated for each type of instrument or medical device set. Further, it may be configured to calculate the optimum number of instruments or medical device sets for each type of instrument or medical device set based on the proportion of instruments or medical device sets that are only being resterilized. ..

Here, the ratio of instruments and medical device sets in which the number of times of re-sterilization is larger than a predetermined number is referred to as "re-sterilization ratio". Here, the predetermined number may be predetermined in the system 10 or may be configured to be arbitrarily set by the operator. By changing the predetermined number, the "resterilization rate" changes.

The system 10 may be configured to extract, for example, an instrument or medical device set having a high resterilization rate for each type of managed instrument or medical device set. In this case, the system 10 may extract instruments and medical device sets in descending order of resterilization rate. In addition, instruments or medical device sets having a re-sterilization ratio of a predetermined ratio or more may be extracted.

In addition, if the instruments and medical device sets are removed in descending order of the number of re-sterilizations, the re-sterilization rate decreases. In addition, the operating rate of instruments and medical instrument sets will be improved, and the man-hours for re-sterilization will be reduced.
Therefore, the system 10 may be configured to calculate the re-sterilization rate for each type of instrument or medical device set, for example, when the instrument or medical device set that is frequently re-sterilized is removed. .. As a result, the system 10 provides data simulating how the operating rate of the instrument or medical device set changes when the number of instruments or medical device sets is reduced in descending order of the number of resterilizations.

The system 10 may be configured to calculate how many instruments or medical device sets that are frequently resterilized should be excluded in order to make the resterilization rate equal to or higher than a predetermined value. As a result, the system 10 provides data indicating how many instruments or medical device sets should be reduced in order to increase the resterilization rate to a predetermined rate or more.

As described above, according to the system 10, the optimum number of instruments and medical device sets can be obtained for each type of instrument and medical device set. The system 10 extracts instruments and medical device sets that have more resterilization times than a predetermined number, and calculates the proportion of instruments and medical device sets that have more resterilization times than a predetermined number. It is good that it is configured to do. And, in fact, by reducing the number of instruments and medical device sets that are frequently sterilized, the operating rate of the instruments and medical device sets is improved, and by only sterilization, the instruments and medical device sets are deteriorated. Is prevented and the number of re-sterilization steps is reduced.

Further, by configuring the device or medical device set to be extracted based on the residual period, for example, in the storage area A6, the device or medical device set having a residual period of 0 can be extracted. .. Further, in the storage area A6, when selecting an instrument or a medical instrument set to be used in the operation area A1, it is possible to take out the instrument or the medical instrument set whose remaining period is not 0 in order from the one having the shortest remaining period. can. By displaying the instrument or medical device set extracted based on the remaining period on the display device 12, the operator can take out the device or the medical device set while checking the screen of the display device 12. .. This prevents the operator from confusing the device or medical device set. Further, in the storage area A6, the system 10 reads the individual information of the bag or container containing the device or medical device set with the reader 11f to determine whether the device or medical device set taken out by the worker is appropriate. It may be configured in.

The system 10 may be composed of only one computer, and the system can be constructed on a stand-alone computer. For example, in a small hospital or the like, the operation area A1 to the storage area A6 may be combined in a space-saving manner. In such a case, the system 10 may be built on one computer.

Further, in this system 10, it is possible to collectively manage information on medical device sets and devices used in a plurality of hospitals by collecting them in a processing device 100. In this case, the surgery area A1 and the collection area A2 are set up in each hospital. In the system 10, it is preferable that the operation terminals 14a to 14f and the processing device 100 of the areas A1 to A6 are connected to each other through the communication network 15 so as to be capable of bidirectional communication. Further, it is preferable that the work history of the instrument or the medical instrument set, the operating rate of the instrument or the medical instrument set, and the like can be provided by the external terminal 21 connected to the system 10 by the cloud computing technology.

The system 10 may be configured such that the sterilization warranty period applied to the instrument or medical device set is displayed on the external terminal 21 in response to a request from the external terminal 21 connected via the communication network 15. .. As a result, the sterilization guarantee period applied to the instrument or medical instrument set managed by the system 10 can be confirmed on the external terminal 21.

The system 10 may be configured such that the remaining period of the sterilization guarantee period of the instrument or medical device set is displayed on the external terminal 21 in response to a request from the external terminal 21 connected via the communication network 15. .. As a result, the remaining period of the sterilization guarantee period of the instrument or medical instrument set managed by the system 10 can be confirmed on the external terminal 21.

Even if the system 10 is configured so that the device or medical device set extracted based on the residual period is displayed on the external terminal 21 in response to a request from the external terminal 21 connected via the communication network 15. good. Thereby, among the instruments or medical device sets managed by the system 10, the instruments or medical device sets extracted based on the remaining period can be confirmed on the external terminal 21.

In this case, a list including the device or medical device set and the remaining period of the device or medical device set may be created and displayed on the external terminal 21. For example, a list of instruments and medical device sets with a residual period of 0, a list of instruments and medical device sets with a residual period of one week or less, and a list of instruments and medical device sets with a residual period of one month or less are created. May be done. In addition, the number and ratio of instruments and medical equipment sets with a residual period of 0, the number and ratio of instruments and medical equipment sets with a residual period of one week or less, and the number and ratio of instruments and medical equipment sets with a residual period of one month or less. However, a graph represented by a bar graph or a pie chart may be created. Further, these lists and graphs may be configured to be created for each affiliation of the device or medical device set, or for each type of device or medical device set, for example. Further, it may be configured to create a graph showing the transition of the number and ratio of instruments and medical device sets having a residual period of 0.

By the way, in the sterilization area A5, a plurality of sterilizers may be prepared for each sterilization method. The sterilization process may take several hours per sterilization. In addition, the high-pressure steam sterilizer may be equipped with a dedicated tray in which a plurality of medical device sets can be set. In addition, a plurality of high-pressure steam sterilizers may be used in parallel at different times in order. As a result, a plurality of medical device sets can be sterilized at the same time by one sterilization process. On the other hand, there are cases where the sterilization process of the medical device set is urgent in response to emergency surgery. At that time, it may occur that the desired sterilizer cannot be used. Therefore, sterilization may not be possible by the predetermined sterilization method specified in the master data.

On the other hand, depending on the medical device set, it may be permitted to sterilize by a method other than the predetermined sterilization method predetermined in the master data. For example, for a particular medical device set, EOG sterilization may be allowed even when the pressure steam sterilizer is set to 120 ° C. for 3 hours. However, in this case, the sterilization guarantee period may differ depending on whether the sterilization is performed in a high-pressure steam sterilizer for 3 hours or EOG sterilization. The present inventor wants to provide a system capable of flexible response in view of such a situation in the medical field.

In the system 10 disclosed here, information for specifying the packaging type is stored in advance. Information that identifies the sterilization type is stored in advance. Furthermore, the relationship between the packaging type, the sterilization type, and the sterilization guarantee period is stored in advance. The system 10 acquires information that identifies the packaging type and information that identifies the sterilization type. The system 10 is configured to obtain a sterilization guarantee period based on the relationship between the packaging type, the sterilization type, and the sterilization guarantee period.

Here, the packaging type specifies the type of packaging material for packaging the medical device or the medical device set, the sealing method, and the like. The sterilization type specifies the sterilization method and sterilization conditions. The packaging type and the sterilization type may be stored in the system 10 in advance. For example, the packaging type and sterilization type may be stored in a database such as master data, as shown in FIG. 4 or 6. Even if the sterilization method is high-pressure steam sterilization (autoclave), the master data may be stored as a different sterilization type for each condition such as temperature and time. In addition to high-pressure steam sterilization (autoclave), ethylene oxide gas sterilization and plasma sterilization may also be stored as different sterilization types depending on conditions such as temperature and time.

FIG. 11 is a diagram showing a configuration example of master data in which the relationship between the packaging type, the sterilization type, and the sterilization guarantee period is stored. The master data 500 in which the relationship between the packaging type, the sterilization type, and the sterilization guarantee period is stored includes, for example, a column 501 for storing the packaging type and a column 502 for storing the sterilization type, as shown in FIG. , A column 503 for storing the sterilization guarantee period is provided. Information for specifying the packaging type is stored in the column 501 for storing the packaging type. Information for identifying the sterilization type is stored in the column 502 for storing the sterilization type. In the column 503 for storing the sterilization guarantee period, information for specifying a predetermined sterilization guarantee period based on the packaging type and the sterilization type is stored.

In this system 10, as shown in FIG. 11, a sterilization guarantee period is obtained based on the relationship between the packaging type, the sterilization type, and the sterilization guarantee period. Therefore, even if the medical device or medical device set is not processed by the sterilization type predetermined by the master data of the medical device or medical device set, an appropriate sterilization guarantee period can be obtained from the packaging type and the sterilization type. can. For example, the packaging type and the sterilization type can be specified based on the master data of the medical device or the medical device set, and an appropriate sterilization guarantee period can be obtained. Further, an appropriate sterilization guarantee period can be obtained from the package type and the sterilization type based on the sterilization type actually processed. As described above, the system 10 can flexibly respond in consideration of the situation in the medical field.

The system 10 may store the device ID associated with the device on a one-to-one basis. Further, a set ID associated with a medical device set composed of a plurality of devices on a one-to-one basis may be stored. Further, the information for specifying the packaging type and the information for specifying the sterilization type may be stored in association with the instrument ID or the set ID. In this case, the information for specifying the packaging type and the information for specifying the sterilization type are acquired in association with the instrument ID or the set ID, and the sterilization guarantee period is based on the relationship between the packaging type, the sterilization type, and the sterilization guarantee period. Is obtained. That is, a sterilization guarantee period based on the packaging type and the sterilization type can be obtained based on the instrument ID or the set ID. In system 10, for example, as shown in FIGS. 3 and 4, master data 400,410 stored in association with an instrument ID or set ID, a predetermined packaging type, and a predetermined sterilization type. May be remembered. Information for identifying the packaging type and information for identifying the sterilization type may be obtained based on the master data, and the sterilization guarantee period may be obtained based on the relationship between the packaging type, the sterilization type, and the sterilization guarantee period.

In this case, the sterilization warranty period is obtained based on the packaging type and sterilization type specified based on the master data. The medical device or medical device set may then be stored and managed based on such sterilization warranty period. In this case, a convenient sterilization guarantee period can be set for the medical device or the medical device set before the sterilization process is performed, for example, in the assembly area A4. The system 10 may include a process of rewriting the packaging type or the sterilization type with respect to the master data stored in association with the instrument ID or the set ID, the packaging type, and the sterilization type. In this case, when the packaging type or sterilization type registered in the master data is rewritten, the standard packaging type or sterilization type of the medical device or medical device set specified by the device ID or set ID is changed. For this reason, the standard sterilization warranty period for medical devices and medical device sets obtained from the packaging type and sterilization type is changed. Since the sterilization warranty period is changed by changing the standard packaging type or sterilization type of the medical device or medical device set specified by the device ID or set ID, the medical treatment specified by the device ID or set ID It is no longer necessary to individually change the sterilization warranty period for instruments and medical device sets.

The system 10 may be configured to obtain a sterilization guarantee period for the medical device set specified by the set ID based on the set ID. In this case, for example, the reader 11 acquires the set ID from the individual information of the medical device set, and obtains the sterilization guarantee period of the medical device set specified by the set ID. Further, it may be configured so that the sterilization guarantee period of the instrument specified by the instrument ID can be obtained based on the instrument ID. In this case, for example, the reader 11 acquires the instrument ID from the individual information of the medical device, and obtains the sterilization guarantee period of the medical device specified by the instrument ID.

The system 10 may store information that identifies a predetermined work to be managed in advance. Further, the system 10 may store a work history including work information of a predetermined work to be managed in association with a set ID for specifying a medical device set or a device ID for specifying a device. Here, the work to be managed may include operations such as surgery, collection, cleaning, assembly (packaging), sterilization, and storage. The work to be managed may be predetermined. The work included in the work to be managed is arbitrarily determined. For example, only assembly (packaging), sterilization, and storage may be controlled.

Although not shown, the system 10 may prepare master data recording the work to be managed. Here, the work to be managed is the work performed on the medical device set or the medical device. The master data may be provided with a column for storing the work name and a column for storing the work ID for identifying the work. In the column for storing the work name, for example, surgery, collection, cleaning, assembly (packaging), sterilization, storage, etc. may be stored. It is preferable that an ID for specifying each work is assigned to the column for storing the work ID for specifying the work. The work ID for identifying the work may be the same as the ID for specifying each work area of surgery, collection, cleaning, assembly (packaging), sterilization, and storage. Further, the work to be managed may be a "controlled process". Further, the work ID for specifying the work may be a process ID for specifying the process.

The work to be managed may include at least packaging work. In this case, the work information of the packaging work included in the work history may include information that identifies when the packaging work is performed. When the latest packaging work included in the work history is performed, the system 10 may add the sterilization guarantee period to obtain the sterilization guarantee period of the medical device or medical device set associated with the packaging work. .. In this case, for example, when the latest packaging work is performed, the sterilization guarantee period is added to obtain the sterilization guarantee period. Since the sterilization work is performed after the packaging work is performed, a sterilization guarantee period with a margin more than the actual time can be obtained. The sterilization guarantee period of the medical device or the medical device set may be acquired when the work information regarding the packaging work is stored in the work history. In this embodiment, the packaging work is a part of the assembly process performed in the assembly area A4, and may be managed as the assembly work. Therefore, the "packaging work" referred to here can be appropriately replaced with the "assembly work".

The work information of the packaging work included in the work history may further include information that identifies the packaging type. The system 10 may acquire information for identifying the packaging type from the work information of the latest packaging operation included in the work history when obtaining the sterilization guarantee period of the medical device or the medical device set. In this case, the packaging type can be obtained from the work information of the latest packaging operation in the work history. Then, a sterilization guarantee period is obtained based on the packaging type. Therefore, when the packaging work is packaged in a packaging type different from the packaging type specified in the master data of the medical device or the medical device set, an appropriate sterilization guarantee period can be obtained according to the packaging operation. Therefore, the system 10 can flexibly respond to the actual packaging work.

The system 10 obtains, for example, a medical device set or a sterilization warranty period for medical devices when the packaging work is completed. In this case, the packaging type may be specified based on work information regarding the packaging operation. The sterilization type may be identified, for example, based on master data. Then, from the specified packaging type and sterilization type, it is preferable that the sterilization guarantee period can be obtained based on the relationship between the packaging type and the sterilization type recorded in the master data and the sterilization guarantee period. The system 10 may obtain the sterilization guarantee period by adding the sterilization guarantee period to the date and time when the packaging work is completed. The medical device set or medical device is then sterilized. Actually, the sterilization guarantee period should be set from the time when the sterilization process is completed, but here, the sterilization guarantee period is intentionally added from the time when the packaging work is completed to obtain the sterilization guarantee period. .. Since the time when the packaging work is completed is before the time when the sterilization process is completed, the sterilization guarantee period obtained here has a margin more than the actual sterilization guarantee period, and the safety is guaranteed more reliably. Can be done. In this way, the system 10 can dare to set the sterilization guarantee period obtained by adding the sterilization guarantee period from the time when the packaging work is completed.

In the system 10, the predetermined work to be managed may include the sterilization work. The work information of the sterilization work included in the work history may include information that identifies when the sterilization work was performed. The system 10 is configured to add the sterilization guarantee period to obtain the sterilization guarantee period of the medical device or medical device set associated with the sterilization work when the latest sterilization work included in the work history is performed. It may have been done. In this case, a medical device or medical device set can be obtained with an appropriate sterilization warranty period according to the actual work. In this case, in addition to the sterilization guarantee period obtained by adding the sterilization guarantee period when the latest packaging work included in the work history is performed, the latest sterilization guarantee period included in the work history is set as the second sterilization guarantee period. When the sterilization work is carried out, the sterilization guarantee period including the sterilization guarantee period may be obtained.

In addition, the work information of the sterilization work included in the work history may further include information for specifying the sterilization type. The system 10 may acquire information for identifying the sterilization type from the work information of the latest sterilization work included in the work history when obtaining the sterilization guarantee period of the medical device or the medical device set. This system 10 can obtain an appropriate sterilization guarantee period according to the actual sterilization work. Therefore, it can be flexibly adapted to the actual sterilization work.

Further, the system 10 may be connectable to a printing machine. The system 10 may be configured such that the printing press prints information A including the sterilization warranty period. For example, as shown in FIG. 2, the printing machine 13 may be arranged in the assembly area A4. In this case, the information A including the sterilization guarantee period is printed in the assembly area A4. For example, in the assembly area A4, the medical device set is packaged in a predetermined packaging material. The system 10 disclosed here can dare to set a sterilization guarantee period obtained by adding a sterilization guarantee period from the time when the packaging work is completed. Then, the information A including the sterilization guarantee period obtained by adding the sterilization guarantee period from the time when the packaging work is completed is printed. The information A including the sterilization guarantee period may be printed, for example, on a label that can be attached to the packaging material. Then, a label on which information A including the sterilization guarantee period is printed may be attached to the packaged medical device set. As a result, the sterilization guarantee period of the packaged medical device set is obtained based on the information A printed on the label. Here, the information printed by the printing machine is particularly referred to as "information A" in order to distinguish it from other information. Such information A may include the "sterilization warranty period" of the packaged medical device or medical device set, as described above. The printed information A may include information for specifying the sterilization guarantee period. For example, characters that can read the "sterilization guarantee period" may be printed. Further, the "sterilization guarantee period" may be printed with a two-dimensional symbol that can be read by the reader 11.

For example, the information A may include information identifying the medical device or medical device set for which the sterilization warranty period has been set. In this case, the medical device or medical device set packaged with the packaging material is specified based on the information A. Further, the information A may include information for specifying the packaging type. In this case, the packaging type can be specified based on the information A. Further, the information A may include information identifying the sterilization type. In this case, the sterilization type can be specified based on the information A. In addition, the information A may include individual information that identifies the packaging material that packages the medical device or the medical device set. For example, "Information A printed on the label includes items that specify the name of the medical device set," "sterilization type," "sterilization warranty period," "individual information that identifies the packaging material," "storage location," and so on. May be included. The "medical device set name", "sterilization type" and "sterilization warranty period" may be, for example, readable characters. The "individual information that identifies the packaging material" may be a two-dimensional symbol that can be read by the reader 11.

In the form shown in FIG. 2, the printing machine 13 is arranged in the assembly area A4. In this case, the sterilization type printed by the printing machine 13 may be the sterilization type stored in the master data in association with the set ID or the instrument ID. Therefore, for example, the sterilization type stored in the master data can be grasped based on the information A printed by the printing machine 13. In this case, it becomes easy for the user working in the sterilization area A5 to grasp the sterilization type stored in the master data.

The system 10 may be configured to obtain information that identifies today's date and obtain the remaining period of the sterilization guarantee based on the information that identifies today's date and the sterilization guarantee expiration date. As the information for identifying today's date, a known method of obtaining the date and time by a computer can be adopted. As for the sterilization guarantee period, the sterilization guarantee period obtained by adding the sterilization guarantee period from the time when the packaging work is completed may be adopted. In this case, the remaining period of the sterilization guarantee is obtained based on the sterilization guarantee period obtained from the time when the packaging work is completed. Since the remaining period is based on the sterilization guarantee period obtained from the time when the packaging work is completed, it is possible to actually set a sufficient period. Further, as for the sterilization guarantee period, the sterilization guarantee period obtained by adding the sterilization guarantee period from the time when the sterilization work is completed may be adopted. In this case, since the residual period of the sterilization guarantee is obtained based on the sterilization guarantee period obtained from the time when the sterilization work is completed, a more accurate residual period of the sterilization guarantee can be set.

The system 10 may be configured to obtain a residual period of sterilization guarantee for the instrument specified by the instrument ID, based on the instrument ID. Further, the system 10 may be configured to obtain the remaining period of the sterilization guarantee of the medical device set specified by the set ID based on the set ID. In this case, the system 10 obtains the remaining period of the sterilization guarantee of the medical device or the medical device set, for example, when the device ID or the set ID is acquired by the reader 11.

The system 10 may extract the instrument ID or set ID based on the residual period of the sterilization guarantee. In this case, the medical device or the medical device set is specified based on the remaining period of the sterilization guarantee, such as the remaining period expired or the remaining period of one week.

The display device 12 can be connected to the system 10. The system 10 may be configured such that the connected display device 12 displays an instrument or medical device set extracted based on the residual period of the sterilization guarantee. The system 10 may also be configured such that the connected display device 12 displays the remaining period of sterilization guarantee for the instrument or medical device set.

The system 10 obtains a sterilization guarantee period based on the time when the packaging work is performed on the medical device or the medical device set and the sterilization guarantee period, and the device ID under predetermined conditions based on the sterilization guarantee period. Alternatively, it may be configured to extract the set ID. That is, the idea is to set the sterilization guarantee period based on the time when the packaging work is carried out and the sterilization guarantee period.

In this case, the system 10 may store the sterilization warranty period set for the medical device or medical device set in association with the device ID or set ID. For example, the sterilization guarantee period may be stored as derived from the packaging type and the sterilization type as described above. If the relationship between the packaging type, the sterilization type, and the sterilization guarantee period is not predetermined, the sterilization guarantee period is predetermined for each medical device or medical device set in association with the device ID or set ID. It is good to be there. Master data that defines the sterilization guarantee period may be prepared in association with the instrument ID or set ID. Further, the time when the packaging work is performed on the medical device or the medical device set may be stored in association with the device ID or the set ID. When the packaging work is carried out, it may be acquired from, for example, the work history of the medical device or the medical device set.

The system 10 may be configured to extract an instrument ID or set ID whose sterilization guarantee period has expired. The system 10 may be configured to extract an instrument ID or set ID for which the remaining period up to the sterilization guarantee period is within a predetermined period. The system 10 may be configured such that the display device 12 is connectable and the display device 12 displays the medical device or medical device set specified by the extracted device ID or set ID. In this case, the display device 12 may display the image of the medical device or the medical device set and the information such as the affiliation of the medical device or the medical device set on the display device 12.

The system 10 extracts an instrument ID or set ID whose sterilization guarantee period has expired, and alerts a predetermined re-sterilization process to the medical device or medical device set specified by the extracted instrument ID or set ID. May be configured to be displayed by the display device 12. The resterilization alert may be configured to indicate the need for resterilization by combining an image of the medical device or medical device set with information such as the affiliation of the medical device or medical device set. Further, for example, the system 10 is configured to determine whether the medical device or the medical device set has passed the sterilization guarantee period when the medical device or the medical device set is specified by the device ID or the set ID. It may have been done. In addition, the system 10 may be configured to display a resterilization alert by the display device 12 if the medical device or medical device set has expired its sterilization warranty period. The medical device or medical device set may also be configured to be added to the list of medical devices or medical device sets that require resterilization if the sterilization warranty period has expired. The resterilization alert includes an indication that the user can recognize that the medical device or medical device set has expired. The method of alerting the resterilization process is not limited unless otherwise specified.

The system 10 may store the work history of a predetermined controlled process performed on the medical device or the medical device set in association with the set ID that identifies the medical device set or the device ID that identifies the device. .. Here, master data for determining the controlled process may be prepared. As the master data for determining the process to be managed, as described above, the master data recording the work to be managed may be used. The master data for determining the process to be controlled should be stored in association with each process such as surgery, collection, cleaning, assembly (packaging), sterilization, and storage, and an ID for specifying the process. ..

The controlled process may include at least a cleaning process, an assembly process, and a sterilization process. Then, the system 10 advances the medical device or the medical device set specified by the extracted device ID or the set ID based on the work history to the storage step after the sterilization step, and then assembles without going through the cleaning step. It may be configured to count the number of steps taken to the steps and sterilization steps. In this case, the number of times that the sterilization step is followed by the storage step and then the assembly step and the sterilization step without going through the cleaning step is synonymous with the number of re-sterilization steps. In this case, the number of times that the sterilization step is followed by the storage step and then the assembly step and the sterilization step without the cleaning step is the number of times that the sterilization step is followed by the storage step but is assembled without the cleaning step. It is the number of times the process and the sterilization process have proceeded, and means the number of times that the process has been continuously re-sterilized. In the re-sterilization process, the medical device or the medical device set is transferred from the storage area A6 to the assembly area A4 (see FIG. 2) and sterilized in the sterilization area A5 without going through the surgical step to the cleaning step. Here, the number of such resterilization treatments is counted. By counting the number of resterilization treatments, it is possible to extract a medical device or a medical device set having a large number of resterilization treatments.

However, in the sterilization process, if the result of the pass / fail judgment of sterilization is "poor", the re-sterilization process is performed. It is not counted in the "number of resterilization processes". In the system 10, the fact that the result of the sterilization quality determination is "poor" means that, for example, the result of the sterilization quality determination is recorded as a record of work information in the sterilization area A5. In the sterilization process, if the result of the sterilization quality judgment is "defective", it is forwarded to the assembly process. Therefore, after the sterilization process, the storage process does not proceed. In the system 10, it is determined whether or not "after the sterilization step, the storage step is proceeded, and then the assembly step and the sterilization step are proceeded without going through the cleaning step". The number of times of the re-sterilization process is determined by whether or not "after the sterilization process, the storage process is performed, and then the assembly process and the sterilization process are performed without going through the cleaning process", and it is determined that the process is "advanced". Is counted by. Therefore, for example, when the result of the quality determination of sterilization is "poor", that is, the sterilization process is redone, the sterilization process proceeds to the assembly process without going through the storage process. Therefore, the re-sterilization process is not counted in the number of re-sterilization processes. Various methods are adopted based on the work history of the medical device or the medical device set to determine whether or not the sterilization step is followed by the storage step and then the assembly step and the sterilization step without going through the cleaning step. sell. Here, for example, it is determined whether or not the storage step is substantially performed after the sterilization step, and then the assembly step and the sterilization step are performed without going through the cleaning step, and the number of resterilization treatments is based on this. It should be counted. Thereby, a process of counting the number of times the medical device or the medical device set proceeds to the storage step after the sterilization step and then to the packaging step and the sterilization step without going through the cleaning step can be realized.

Further, the system 10 "the number of times that the system 10 proceeded to the storage step after the sterilization step and then to the assembly step and the sterilization step without going through the cleaning step" was, for example, proceeded to the assembly step through the cleaning step after the storage step. In some cases, it may be reset to 0. Whether or not the process proceeds to the assembly process through the cleaning process after the storage process may be determined based on the work history of the medical device or the medical device set. For example, the system 10 may determine whether or not the assembly process has proceeded through a surgical process or a cleaning process. Then, when it is determined that the assembly process has proceeded through the surgical process or the cleaning process, the number of re-sterilization processes may be reset to 0. After the sterilization step, the number of re-sterilization treatments is set to 0 when the process proceeds to the storage step and then the washing step is performed. As a result, the number of times the re-sterilization process is repeated is counted as the number of times the re-sterilization process is performed.

The system 10 is configured to extract a medical device or a medical device set in which the number of resterilization processes exceeds a predetermined number of times, and execute a predetermined alert process for the medical device or the medical device set. It may have been done. Here, the predetermined alert process may be, for example, a process of displaying a list of extracted medical devices or medical device sets on the display device 12. Further, for example, in the system 10, when the extracted medical device or medical device set is selected by the user, the display device 12 displays that the number of resterilization treatments exceeds a predetermined number of times. It may be configured as follows. The alert processing may be to sound a predetermined warning sound when the extracted medical device or medical device set is selected by the user. Note that alert processing is not limited to those mentioned here.

FIG. 15 is a diagram showing a configuration example of master data for recording the number of times of re-sterilization. As shown in FIG. 15, the master data 600 includes an instrument ID or set ID, individual information of the packaging material, the number of times of continuous re-sterilization, a sterilization guarantee period 1, and a sterilization guarantee period 2. It is provided with columns 601 to 605 for recording and. In the field 601 for storing the device ID or set ID, the device ID or set ID of the medical device or medical device set registered in the system 10 is recorded. In the column 602 for storing the individual information of the packaging material, the individual information of the packaging material packaged in the latest assembly process is stored. The value in this column 602 is updated when the work information of the assembly process is recorded. In the sterilization guarantee period 1, the date when the sterilization guarantee period is added to the work end date and time of the latest assembly process is stored. In the sterilization guarantee period 2, the date in which the sterilization guarantee period is added to the work end date and time when the sterilization is judged to be "good" is stored in the latest sterilization process.

According to the master data 600, for a medical device or a medical device set, the sterilization guarantee period is added to the individual information of the packaging material packaged in the latest assembly process, the number of times of re-sterilization, and the work end date and time of the latest assembly process. It becomes easy to manage the first sterilization guarantee period and the second sterilization guarantee period, which is obtained by adding the sterilization guarantee period to the work end date and time when the sterilization is judged to be "good" among the latest sterilization steps. It should be noted that such information may be derived each time by quoting necessary information from other master data or work history without preparing dedicated master data.

The system 10 can be connected to the printing machine 13 as described above, and the printing machine 13 may be configured to print information including the sterilization guarantee period. Further, the system 10 may be set whether or not the printing machine 13 prints information including the sterilization guarantee period in association with the instrument ID or the set ID. For example, as shown in FIG. 4, in the master data registered in association with the medical device set, a column 419 for setting whether or not the printing machine 13 prints may be provided. The system 10 may refer to the master data registered in association with the medical device set and determine whether or not the printing machine 13 needs to print the medical device set. In this case, the system 10 may be configured so that information including the sterilization guarantee period is appropriately printed by the printing machine 13 for the medical device set for which printing by the printing machine 13 is set to "○: required". ..

In the system 10, the extracted device ID or the medical device or the medical device set specified by the set ID proceeds to the storage step after the sterilization step based on the work history, and then the assembly step without going through the cleaning step.

It also reduces the management cost of medical devices or sets of medical devices.

Further, in the system 10, the medical device or the medical device set specified by the device ID or the set ID extracted based on the work history proceeds to the storage step after the sterilization step, and then does not go through the cleaning step. For an instrument or medical device set in which the number of times the assembly process and the sterilization process have been performed exceeds a predetermined number of times, the printing machine 13 may be set not to print information including the sterilization guarantee period. In this case, if the number of times of continuous re-sterilization exceeds a predetermined number of times, it is set that the information including the sterilization guarantee period is not printed. Therefore, the medical device or the medical device set is excluded from the objects to be continuously resterilized without requiring artificial judgment. This can reduce the number of medical devices or medical device sets that are continuously resterilized, reducing the number of resterilization processes. Reduced management costs for medical devices or sets of medical devices. The medical device or medical device set can be managed by the system 10 even if it is excluded from the subject to be resterilized. The system 10 maintains the sterilization warranty period of these medical devices or medical device sets as they are. These medical devices or sets of medical devices can be identified in System 10 as out of sterilization.
