[0013] The background and problems of the prior art will now be described in more detail.

[0014] Biochemical analyzers are devices for measuring components of human body fluids such as blood and urine, and are widely used in hospital laboratories and testing centers. In recent years, changes in the medical environment have created strong demands for analytical devices such as biochemical analyzers to provide high-quality data, enable rapid testing, and improve testing efficiency. However, there has been a problem in that air bubbles mixed in reverse osmosis (RO) water used in analytical processing by the analyzers reduce the analytical accuracy of the processing.

[0015] An effective way to solve this problem is to remove dissolved gases from the RO water. One known method for efficiently removing dissolved gases is to incorporate a hollow fiber degassing module into an analytical device to perform continuous degassing. Requirements for incorporating a hollow fiber degassing module into an analytical device include a required degassing performance, a small size (compact size) that can be installed in the device, low pressure loss, and a long life.

[0016] Once installed in an analytical instrument, the degassing module is used continuously for a long period of time. Consequently, vaporized water accumulates in the vacuum section and vacuum path within the degassing module, causing performance degradation. The drainage container, which contains the liquid discharged from the outlet of the discharge pipe connected to the degassing module, is periodically discarded by a laboratory technician or other maintenance manager.

[0017] For example, a maintenance manager periodically visually checks the drain container, which serves as a liquid reservoir and is located inside the analyzer. The maintenance manager checks for any abnormalities using a pressure sensor of a vacuum unit located between the degassing module and the outlet of the discharge pipe inside the analyzer. The maintenance manager discards the wastewater when a predetermined amount of wastewater has accumulated in the drain container.

[0018] However, the maintenance manager was unable to accurately determine that the hollow fibers used in the degassing module had broken due to deterioration, causing a liquid leak. The maintenance manager was unable to accurately determine the deterioration of the hollow fibers. Repairs to the analyzer are handled by a medical device service engineer, who is a different type of maintenance manager than the laboratory technician. The service engineer checks the analyzer and replaces the degassing module, among other tasks. This service engineer was also unable to accurately determine the deterioration of the hollow fibers.

[0019] If liquid leaks from the hollow fibers into the reduced pressure space due to deterioration of the hollow fibers or other reasons, the discharge device will operate and the leaked liquid will be discharged from the discharge device into the analyzer through the vacuum piping. As a result, devices such as the discharge device installed in the analyzer may become wet and malfunction. To avoid such equipment malfunctions, maintenance personnel must personally monitor for liquid leaks from the degassing module of the analyzer, which requires a great deal of effort in maintaining and managing the analyzer equipped with a degassing module.

[0020] In order to solve the above-mentioned problems, an object of the present disclosure is to provide an information processing device, an information processing system, an information processing method, and a program that can improve the convenience of an analysis device.

[0021] An embodiment of the present disclosure will be mainly described below with reference to the accompanying drawings. The following description also applies to an information processing system 1 including an information processing device 10, to which the present disclosure is applied, and an information processing method and program executed by the information processing device 10.

[0022] (First embodiment) Fig. 1 is a block diagram showing an example of the configuration of an information processing device 10 according to a first embodiment of the present disclosure. An example of the configuration and functions of the information processing device 10 according to the first embodiment of the present disclosure will be mainly described with reference to Fig. 1. The information processing device 10 has a communication unit 11, a storage unit 12, a degassing unit 13, a sensor unit 14, an input unit 15, an output unit 16, a control unit 17, an exhaust unit 18a, an exhaust pipe unit 18b, and a container unit 19.

[0023] In the first embodiment, the information processing device 10 is configured as an analysis device, for example. In the present disclosure, the "analysis device" includes, for example, a biochemical analysis device for measuring components of human body fluids such as blood and urine. The biochemical analysis device includes, for example, a liquid chromatography device. The information processing device 10 is used to monitor liquid leakage from a degassing module included in the degassing unit 13.

[0024] The communication unit 11 includes one or more communication interfaces. The communication interfaces include, for example, one or more communication interfaces for connecting to a network. The communication interfaces are compatible with mobile communication standards such as 4th Generation (4G) and 5th Generation (5G), wired Local Area Network (LAN) standards, or wireless LAN standards, but are not limited to these and may be compatible with any communication standard. The information processing device 10 may be communicably connected to the network via the communication unit 11. The communication unit 11 may transmit and receive various information via the network.

[0025] Additionally, the communication interface of the communication unit 11 may be compatible with any wireless communication standard or wired communication standard for wireless or wired communication. The wireless communication standard includes Bluetooth (registered trademark), Wi-Fi (registered trademark), ZigBee (registered trademark), and any other short-range wireless communication standard. The wired communication standard includes a communication standard such as USB (Universal Serial Bus).

[0026] The storage unit 12 includes storage modules such as a hard disk drive (HDD), a solid state drive (SSD), an electrically erasable programmable read-only memory (EEPROM), a read-only memory (ROM), and a random access memory (RAM). The storage unit 12 stores information necessary to realize the operation of the information processing device 10. The storage unit 12 stores information obtained by the operation of the information processing device 10. The storage unit 12 stores system programs, application programs, and various data obtained by any means such as communication.

[0027] The storage unit 12 may function as a main storage module, an auxiliary storage module, or a cache memory. The storage unit 12 is not limited to being built into the information processing device 10, and may include an external storage module connected via a digital input / output port such as a USB.

[0028] The degassing unit 13 includes one or more degassing modules. The degassing modules include hollow fiber degassing modules. The hollow fiber degassing modules have a hollow fiber membrane bundle in which multiple hollow fiber membranes are bundled together in a bamboo blind shape with warp threads. The information processing device 10 as an analytical device performs chemical or biochemical analysis of a sample. The information processing device 10 as an analytical device reduces the pressure on the outside or inside of the hollow fiber membranes of the degassing module, thereby separating only gas in the liquid from the liquid via the wall surfaces of the hollow fibers as the liquid passes through the inside or outside of the hollow fiber membranes.

[0029] The degassing module may include, for example, an external perfusion type hollow fiber degassing module. The degassing module may degas the isothermal water by supplying constant temperature water to the outside of the hollow fiber membrane and reducing the pressure inside the hollow fiber membrane, thereby producing degassed isothermal water. Without being limited thereto, the degassing module may include, for example, an internal perfusion type hollow fiber degassing module. The degassing module may degas the isothermal water by supplying constant temperature water to the inside of the hollow fiber membrane and reducing the pressure outside the hollow fiber membrane, thereby producing degassed isothermal water.

[0030] The hollow fiber membrane of the degassing module is a hollow fiber membrane that allows gas to pass through but not liquid to pass through. The material, shape, and form of the hollow fiber membrane are not particularly limited. From the viewpoints of ease of manufacture, chemical resistance, and fouling resistance, examples of materials for the hollow fiber membrane include polyolefin resins such as polypropylene and poly(4-methylpentene-1, hereinafter also referred to as "PMP"), PTFE, amorphous fluoropolymers, tetrafluoroethylene-perfluoroalkyl vinyl ether copolymers, tetrafluoroethylene-hexafluoropropylene copolymers, tetrafluoroethylene-ethylene copolymers, polychlorotrifluoroethylene, and fluororesins such as polyvinylidene fluoride. More specifically, the amorphous fluoropolymer may be an amorphous fluororesin comprising a copolymer with tetrafluoroethylene and perfluoro-2,2-dimethyl-1,3-dioxole as comonomers.

[0031] Examples of the membrane shape (sidewall shape) of hollow fiber membranes include porous membranes, microporous membranes, and homogeneous membranes (non-porous membranes) that do not have porosity. Examples of the membrane form of hollow fiber membranes include symmetric membranes (homogeneous membranes) in which the chemical or physical structure of the entire membrane is homogeneous, and asymmetric membranes (heterogeneous membranes) in which the chemical or physical structure of the membrane varies depending on the membrane. An asymmetric membrane (heterogeneous membrane) is a membrane that has a non-porous dense layer and a porous layer. In this case, the dense layer may be formed anywhere in the membrane, such as the surface layer of the membrane or the inside of the porous membrane. Heterogeneous membranes also include composite membranes with different chemical structures and multilayer structure membranes such as a three-layer structure.

[0032] For example, a heterogeneous membrane using a PMP resin has a dense layer that blocks liquids, and is therefore particularly suitable for degassing liquids other than water, such as constant-temperature water. In the case of hollow fibers used in external perfusion systems, it is preferred that a dense layer be formed on the outer surface of the hollow fibers.

[0033] The hollow fiber membrane bundle can be formed, for example, into a sheet-like material in which a plurality of hollow fiber membranes are bundled together with warp threads in a bamboo blind shape. In this case, for example, the sheet-like material is wound to form a hollow fiber membrane bundle, and both ends of the hollow fiber membrane bundle are fixed with a sealing material to produce a hollow fiber degassing module. From the viewpoints of ease of manufacture, chemical resistance, and stain resistance, preferred materials for the warp threads include polyolefin resins such as polypropylene resin, the above-mentioned fluororesins, and aromatic polyester resins such as polycarbonate resin and polyethylene terephthalate.

[0034] The sensor unit 14 acquires liquid leakage information of the liquid discharged from the degassing module of the degassing unit 13. In the present disclosure, "liquid leakage information" includes, for example, liquid level information of the liquid in the container unit 19 and the pressure inside the discharge pipe unit 18b. "Liquid level information" includes, for example, the time when the liquid level of the liquid in the container unit 19 changes by a predetermined amount. In addition, the liquid level information may include any other parameter related to the liquid level, such as the height of the liquid level, as long as the information processing device 10 can determine whether or not there is an abnormality in the liquid leakage from the degassing module of the degassing unit 13.

[0035] The sensor unit 14 may include, for example, a liquid level sensor disposed in the container unit 19. The liquid level sensor acquires information about the liquid level of the liquid in the container unit 19 as liquid leakage information. The sensor unit 14 may include, for example, a pressure sensor disposed in the discharge pipe unit 18b between the outlet 18c of the discharge pipe unit 18b and the degassing unit 13. The pressure sensor acquires the pressure inside the discharge pipe unit 18b as liquid leakage information. The sensor unit 14 may include at least one of a liquid level sensor and a pressure sensor.

[0036] The input unit 15 includes one or more input interfaces that detect user input and acquire input information based on the user's operation. The input interfaces include physical keys, capacitive keys, a touch screen that is integrated with the display of the output unit 16, an imaging module such as a camera, and a microphone that accepts audio input.

[0037] The output unit 16 includes one or more output interfaces that output information to provide it to the user. The output interfaces include a display that outputs information visually as an image, a speaker that outputs information audibly as sound, and a vibrator that outputs information tactilely as vibration. The display includes an LCD (Liquid Crystal Display) and an organic EL (Electro Luminescence) display.

[0038] The control unit 17 includes one or more processors. The processors may be, but are not limited to, a general-purpose processor or a dedicated processor specialized for a specific process. The control unit 17 includes, for example, a CPU (Central Processing Unit). The control unit 17 is communicably connected to each component of the information processing device 10 and controls the operation of the information processing device 10 as a whole.

[0039] FIG. 2 is a schematic diagram showing a portion of the configuration of the information processing device 10 of FIG. 1 . FIG. 2 mainly shows a configuration arranged between the PMP degassing module of the degassing unit 13 and the outlet 18c of the exhaust pipe 18b, which is an example of an information processing device 10 as an analytical device. Pre-degassed liquid W1 flows into the PMP degassing module of the degassing unit 13. The liquid W1 includes, for example, RO water and constant temperature water. The inflowing liquid W1 is degassed by the PMP degassing module of the degassing unit 13 and flows out of the PMP degassing module as treated liquid W2. Gas extracted from the liquid W1 in the PMP degassing module of the degassing unit 13 passes through the exhaust pipe 18b and is exhausted from the outlet 18c of the exhaust pipe 18b.

[0040] The exhaust unit 18a exhausts air from the degassing unit 13 to the outlet 18c. The exhaust unit 18a includes, for example, a vacuum pump. The vacuum pump of the exhaust unit 18a sucks gas from a portion of the degassing unit 13 and the exhaust pipe unit 18b to achieve a vacuum state in the portion of the degassing unit 13 and the exhaust pipe unit 18b at a predetermined vacuum level. The exhaust pipe unit 18b is connected to the degassing unit 13. The exhaust pipe unit 18b includes, for example, any exhaust pipe whose interior is evacuated by the vacuum pump of the exhaust unit 18a. The degassing unit 13, the exhaust unit 18a, and the outlet 18c are arranged consecutively in order along the exhaust pipe unit 18b.

[0041] For example, the pressure sensor 141 of the sensor unit 14 is disposed relative to the discharge pipe 18b between the outlet 18c of the discharge pipe 18b and the degassing unit 13. The pressure sensor 141 acquires, as liquid leakage information, the pressure inside the discharge pipe 18b, where a vacuum state is realized by the vacuum pump of the exhaust unit 18a.

[0042] Fig. 3 is a schematic diagram showing another part of the configuration of the information processing device 10 shown in Fig. 1. Fig. 3 shows a schematic diagram of the configuration arranged around the outlet 18c of the discharge pipe 18b of the information processing device 10 as an analysis device.

[0043] The container 19 contains the liquid discharged from the outlet 18c of the discharge pipe 18b. The container 19 includes, for example, a drain container. The drain container of the container 19 functions as a liquid reservoir for receiving the liquid discharged due to liquid leakage from the degassing module of the degassing unit 13.

[0044] For example, the liquid level sensor 142 of the sensor unit 14 is disposed in the drain container of the container unit 19. The liquid level sensor 142 acquires information about the liquid level in the container unit 19 as liquid leakage information.

[0045] Fig. 4 is a flowchart for explaining an example of an information processing method executed by the information processing device 10 of Fig. 1. With reference to Fig. 4, an example of the information processing method executed by the control unit 17 of the information processing device 10 of Fig. 1 will be mainly explained. The information processing method is used for monitoring liquid leakage from the degassing module of the degassing unit 13.

[0046] In step S101, the control unit 17 of the information processing device 10 acquires reference information in advance. In the present disclosure, "reference information" includes, for example, any information that is compared with the liquid leakage information when the information processing device 10 executes a process for determining whether or not liquid leakage from the degassing module of the degassing unit 13 is abnormal. The reference information includes, for example, a first threshold value for the time it takes for the liquid level in the container unit 19 to change by a predetermined amount, and a second threshold value for the pressure inside the discharge pipe unit 18b. The control unit 17 stores the acquired reference information in the memory unit 12.

[0047] In step S102 , the control unit 17 of the information processing device 10 uses the sensor unit 14 to acquire liquid leakage information of the liquid discharged from the degassing module of the degassing unit 13 .

[0048] In step S103, the control unit 17 of the information processing device 10 compares the liquid leakage information acquired in step S102 with the reference information acquired in advance in step S101. The control unit 17 reads out the reference information stored in the storage unit 12 in step S101 from the storage unit 12 and uses it for comparison with the liquid leakage information.

[0049] In step S104, the control unit 17 of the information processing device 10 determines whether or not there is an abnormality in the liquid leakage from the degassing module of the degassing unit 13 based on the comparison process of step S103. For example, the control unit 17 acquires, as liquid level information, the time required for the liquid level in the container unit 19 to change by a predetermined amount using the liquid level sensor 142, and determines that there is an abnormality in the liquid leakage if the acquired time is shorter than a first threshold value as reference information. For example, the control unit 17 determines that there is an abnormality in the liquid leakage if the pressure inside the discharge pipe unit 18b acquired by the pressure sensor 141 is greater than a second threshold value as reference information. If the control unit 17 determines that there is an abnormality in the liquid leakage, it executes the process of step S106. If the control unit 17 determines that there is normality in the liquid leakage, it executes the process of step S105.

[0050] In step S105, if the control unit 17 of the information processing device 10 determines in step S104 that the liquid leakage is normal, the control unit 17 executes an analysis process of the analysis target using the processing liquid W2 degassed by the degassing unit 13.

[0051] In step S106, if the control unit 17 of the information processing device 10 determines in step S104 that the liquid leakage is abnormal, it generates notification information indicating the determination result of step S104. In the present disclosure, "notification information" includes visual information, auditory information, tactile information, etc. for warning the notification target that the liquid leakage is abnormal. The "notification target" includes, for example, a maintenance manager who performs maintenance management of the information processing device 10 as an analytical device, and other users who use the information processing device 10 but are different from the maintenance manager. The "maintenance manager" includes, for example, a laboratory technician who performs maintenance management on a daily basis, and a medical device service engineer who is different from the laboratory technician.

[0052] In step S107, the control unit 17 of the information processing device 10 outputs the notification information generated in step S106 to the notification target via the output unit 16. For example, the control unit 17 displays the visual information generated as the notification information in step S106 on the display of the output unit 16. For example, the control unit 17 outputs the auditory information generated as the notification information in step S106 from the speaker of the output unit 16. For example, the control unit 17 outputs the tactile information generated as the notification information in step S106 from the vibrator of the output unit 16.

[0053] In step S108, the control unit 17 of the information processing device 10 provides accuracy information indicating that the accuracy of the analytical data of the analytical processing has decreased in accordance with the determination result of step S104, along with the analytical data. For example, the control unit 17 outputs the accuracy information and analytical data to the notification recipient via the output unit 16, similar to the notification information in step S107. For example, the control unit 17 displays the accuracy information and analytical data on the display of the output unit 16.

[0054] The information processing device 10 according to the first embodiment described above can improve the convenience of an analytical device. When the information processing device 10 determines that a liquid leak is abnormal by comparing acquired liquid leakage information with previously acquired reference information, it generates notification information indicating the determination result. By acquiring the liquid leakage information and comparing it with the reference information, the information processing device 10 can automatically monitor for liquid leakage from the degassing module. Therefore, a maintenance manager does not need to monitor for liquid leakage by visual inspection or the like, as in the past, and the labor required for maintaining and managing an analytical device having a degassing module can be reduced.

[0055] By automatically monitoring for liquid leakage, the information processing device 10 can prevent device failure due to leakage of liquid discharged from the degassing module. For example, a maintenance manager can utilize the automatic monitoring of liquid leakage by the information processing device 10 to reduce the likelihood of overlooking abnormal liquid leakage. For example, the maintenance manager can more reliably discard the drained liquid accumulated in the container unit 19 before the container unit 19 becomes full of liquid and overflows. As a result, device failure due to liquid leakage is avoided.

[0056] The information processing device 10 has, for example, a sensor unit 14, and by acquiring liquid leakage information using the sensor unit 14, it is possible to estimate deterioration of the hollow fibers in the degassing module of the degassing unit 13 in the information processing device 10 as an analytical device based on the liquid leakage information. For example, if the information processing device 10 determines based on the liquid leakage information that a large amount of liquid is being discharged from the degassing module of the degassing unit 13 and that there is abnormal liquid leakage, it can also mechanically estimate that the hollow fibers in the degassing module have broken. Therefore, for example, a testing engineer can determine deterioration of the degassing module himself / herself without relying on a service engineer.

[0057] By generating notification information, the information processing device 10 can accurately notify a maintenance manager or the like of the status of the analytical device via the output unit 16. For example, the information processing device 10 can accurately notify a maintenance manager via the output unit 16 of deterioration of the hollow fibers in the degassing module of the degassing unit 13 included in the analytical device.

[0058] The sensor unit 14 is disposed in the container unit 19 and includes a liquid level sensor 142 that acquires information about the liquid level in the container unit 19 as liquid leakage information. This allows the information processing device 10 to directly monitor the amount of liquid being discharged from the degassing module of the degassing unit 13. This allows the information processing device 10 to more accurately determine whether there is an abnormality in the liquid leakage from the degassing module.

[0059] The information processing device 10 acquires the time when the liquid level in the container 19 changes by a predetermined amount as liquid level information using the liquid level sensor 142, and determines that a liquid leak is abnormal if the time is shorter than a first threshold value serving as reference information. This allows the information processing device 10 to more accurately determine whether a liquid leak is abnormal, based on the speed at which the liquid discharged from the degassing module of the degassing unit 13 accumulates in the container 19.

[0060] The sensor unit 14 is disposed on the discharge pipe 18b between the outlet 18c of the discharge pipe 18b and the degassing unit 13, and includes a pressure sensor 141 that acquires the pressure inside the discharge pipe 18b as liquid leakage information. This allows the information processing device 10 to indirectly monitor the amount of liquid being discharged from the degassing module of the degassing unit 13 based on the pressure inside the discharge pipe 18b. The information processing device 10 can also determine an abnormality in liquid leakage from the degassing module using the pressure sensor 141 alone, without additionally disposing a liquid level sensor 142 on the container 19. The information processing device 10 can also simplify its configuration by omitting the liquid level sensor 142 on the container 19.

[0061] The information processing device 10 determines that a liquid leak is abnormal if the pressure acquired by the pressure sensor 141 is greater than a second threshold value serving as reference information. This allows the information processing device 10 to more accurately determine whether a liquid leak is abnormal, based on the increase in pressure inside the discharge pipe portion 18b caused by the liquid being discharged from the degassing module of the degassing unit 13.

[0062] In the information processing device 10, the degassing unit 13, the exhaust unit 18a, and the outlet 18c of the exhaust pipe unit 18b are arranged in sequence and continuously along the exhaust pipe unit 18b. This allows the information processing device 10 to omit components such as a vacuum unit and a drain pot that conventional analytical devices have between the degassing module and the outlet of the exhaust pipe, thereby making the entire device smaller. By simplifying the configuration from the degassing unit 13 to the outlet 18c, the information processing device 10 can be configured as a small analytical device that can be placed on a table, for example.

[0063] Such miniaturization can be achieved, for example, by using the above-mentioned preferred materials in the degassing module of the degassing unit 13. By including such a degassing module in the degassing unit 13, the information processing device 10 can further reduce the amount of liquid leakage compared to conventional large degassing modules, for example, those using silicone hollow fibers. In addition to miniaturizing the degassing module itself, the information processing device 10 can also reduce the overall size of the device by eliminating components such as a vacuum unit and a drain pot due to the reduced amount of liquid leakage. The information processing device 10 can achieve a device structure that is less likely to degrade the performance of the degassing module of the degassing unit 13, even when used as an analytical device for a long period of time. The degassing module of the degassing unit 13 can maintain its original excellent degassing performance even during long-term continuous use.

[0064] The information processing device 10 provides, together with the analytical data, accuracy information indicating that the accuracy of the analytical data from the analytical process has decreased according to the determination result. As a result, for example, a notification recipient who receives the accuracy information and analytical data via the output unit 16 or the like can easily determine that the analytical data is unreliable as data and discard it without using it in the analysis of the analysis target.

[0065] In the first embodiment, the information processing device 10 is described as being configured as an analyzer, but is not limited thereto. The information processing device 10 may be configured as any other device having a degassing module. For example, the information processing device 10 may be configured as an inkjet printer having a degassing module for degassing ink.

[0066] In the first embodiment, the analyzer is described as including a biochemical analyzer such as a liquid chromatography device, but is not limited thereto. The analyzer may also include other devices that analyze analytes other than components of human body fluids such as blood and urine.

[0067] In the first embodiment, the sensor unit 14 is described as including at least one of the liquid level sensor 142 and the pressure sensor 141, but is not limited to this. The sensor unit 14 may also include any other sensor capable of acquiring liquid leakage information used in the process of determining whether or not liquid leakage from the degassing module is abnormal.

[0068] In the first embodiment, the degassing unit 13, the exhaust unit 18a, and the outlet 18c are described as being arranged in sequence along the discharge pipe 18b, but this is not limiting.

With reference to Fig. 6, an example of an information processing method executed by the information processing system 1 of Fig. 1 will be mainly explained.

[0091] In step S201, the control unit 43 of the information processing device 10 acquires reference information in advance, similarly to step S101 in Fig. 4. The control unit 43 stores the acquired reference information in the storage unit 42.

[0093] In step S203, the control unit 27 of the analysis device 20 provides the liquid leakage information acquired in step S202 to the information processing device 10. For example, the control unit 27 transmits the liquid leakage information to the information processing device 10 via the communication unit 21 and the network 40.

[0095] In step S205, the control unit 43 of the information processing device 10 determines that the liquid leakage is abnormal based on the same determination process as in step S104 of FIG.

[0096] In step S206, if the control unit 43 of the information processing device 10 determines in step S205 that the liquid leakage is abnormal, it generates notification information indicating the determination result in step S205, similar to step S106 in FIG.
