[0003] [Patent Document 1] JP 2000-341375 A Summary of the Invention [Problem to be solved by the invention]

[0004] Some human bad breath is caused by internal diseases such as periodontal disease and visceral disease, and specific substances are detected in the breath of patients suffering from periodontal disease, visceral disease, and other diseases. Therefore, it is expected that the degree of periodontal disease, for example, can be estimated by determining the components of human breath. However, the components of human breath may contain various odors such as odors caused by food residues (noise odors) in addition to odors caused by periodontal disease, and the composition of the components of human breath is complex. Therefore, for example, when the breath of a user is measured using the mobile phone disclosed in Patent Document 1, it is difficult to accurately estimate the degree of periodontal disease due to the influence of noise odors caused by food residues, and only the degree of bad breath can be determined.

[0014] Hereinafter, the embodiments will be described in detail with reference to the drawings. However, more detailed description than necessary may be omitted. For example, detailed description of already well-known matters or duplicate description of substantially the same configuration may be omitted. Note that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0015] (Schematic configuration of periodontal disease assessment system 1) The periodontal disease determination system 1 according to this embodiment cleans the inside of the user's mouth with an oral irrigator 10 equipped with a gas sensor 12, detects the exhaled breath after cleaning, and transmits frequency component information of the detected exhaled breath to a terminal 20 via a network 30. The terminal 20 then determines the frequency component of the exhaled breath and estimates periodontal disease. The periodontal disease determination system 1 will be described below with reference to several specific embodiments.

[0016] (First embodiment) 1 is a schematic diagram showing a configuration of a periodontal disease determination system 1 according to the first embodiment. The periodontal disease determination system 1 includes an oral irrigator 10 equipped with a gas sensor 12, and a terminal 20.

[0017] The oral irrigator 10 includes a cleaning unit 11, a gas sensor 12, a switch 13, a display unit 14, and a water tank 15. The oral irrigator 10 also includes a controller 100. The controller 100 will be described in detail later.

[0018] The cleaning unit 11 has a nozzle and discharges a water flow for oral cleaning through the nozzle. In addition, a discharge ON / OFF switch (not shown) that controls the on / off of the water flow discharge from the nozzle is provided on the nozzle grip of the cleaning unit 11. When the user presses the discharge ON / OFF switch, water stored in the water tank 15 is discharged through a hose connected to the oral irrigator 10 and the nozzle.

[0019] The nozzle of the cleaning unit 11 is also used to collect the breath of the user. Specifically, the user blows breath into the tip of the nozzle, so that the breath of the user is taken into the oral irrigator 10. The taken-in breath of the user reaches the gas sensor 12 provided inside the oral irrigator 10, where it is sensed.

[0020] The oral irrigator 10 has an oral cleaning mode in which a water flow is discharged from a nozzle, and an exhaled breath collection mode in which exhaled breath is collected from the nozzle. Note that switching between the oral cleaning mode and the exhaled breath collection mode is performed by a switch 13, and the mode is switched in response to the user pressing the switch 13.

[0021] The gas sensor 12 is a quartz crystal type gas sensor equipped with multiple sensitive films with different characteristics, and detects whether or not a predetermined frequency component is present in the user's breath collected through the nozzle of the cleaning unit 11. The gas sensor 12 can detect (sense) gases corresponding to multiple odors.

[0022] The oral irrigator 10 also includes a filter (not shown) capable of adjusting the humidity of the breath flowing between the nozzle of the cleaning unit 11 and the gas sensor 12. This filter has a function of removing moisture contained in the collected breath of the user. By using this filter, it is possible to reduce the effect of moisture contained in the breath on the gas sensor 12.

[0023] Generally, the main components of odor in the oral cavity (bad breath) are volatile sulfur compounds (VSCs). These volatile sulfur compounds mainly consist of three types of gases: hydrogen sulfide, methyl mercaptan, and dimethyl sulfide. Among these, methyl mercaptan is particularly detected in the breath of patients with periodontal disease. In this embodiment, the degree of periodontal disease is estimated based on the correlation between this methyl mercaptan and hydrogen sulfide used as reference data. In this specification, reference data has a specific relationship with the data (substance) to be measured. By examining the correlation between this reference data and the data to be measured, it becomes possible to recognize the characteristics of the data to be measured in more detail. In this embodiment, methyl mercaptan, which is the data to be measured, and hydrogen sulfide, which is the reference data, a certain amount of hydrogen sulfide is detected in the breath in which methyl mercaptan is detected. Therefore, by estimating the degree of periodontal disease based on the correlation between methyl mercaptan and hydrogen sulfide, it becomes possible to estimate the degree of periodontal disease more accurately than by simply estimating the degree using methyl mercaptan. Dimethyl sulfide is a substance that is often detected in the breath of patients with visceral diseases.

[0024] In addition, in this embodiment, the gas sensor 12 is a quartz crystal resonator gas sensor, but the configuration is not limited to this, and the gas sensor 12 may be an oxide semiconductor gas sensor or another gas sensor.

[0025] The switch 13 is a switch for switching the oral irrigator 10 between an oral cleaning mode and an exhaled breath collection mode, and is pressed by the user. Pressing information of the switch 13 pressed by the user is notified to the controller 100 in the oral irrigator 10. The switch 13 may be composed of a plurality of switches corresponding to the oral cleaning mode and the exhaled breath collection mode, respectively. Alternatively, the switch 13 may be configured to switch among the standby mode, the oral cleaning mode, and the exhaled breath collection mode in the order in which the user presses the switch.

[0026] The display unit 14 is a lamp that indicates whether the mode switched (selected) by the switch 13 is the oral cleaning mode or the breath sampling mode. The display unit 14 may also have a function of lighting up in a standby state (standby mode).

[0027] (Functional configuration of oral irrigator 10) Next, the functions of the oral irrigator 10 and the controller 100 will be described with reference to the functional block diagram shown in FIG.

[0028] The controller 100 includes a control unit 110, a storage unit 120, a communication IF 130, and an input / output IF 140. The controller 100 may be configured as a general-purpose microcomputer including a CPU (control unit 110), a memory (storage unit 120), and an input / output unit (communication IF 130 and input / output IF 140). In this case, a computer program for causing the microcomputer to function as the oral irrigator 10 may be installed in the microcomputer. By executing the computer program, the microcomputer functions as a plurality of information processing circuits included in the oral irrigator 10. Note that in this embodiment, an example is shown in which a plurality of information processing circuits included in the oral irrigator 10 are realized by software, but it is of course possible to configure the information processing circuit by preparing dedicated hardware for executing each of the information processes shown below. Also, a plurality of information processing circuits may be configured by individual hardware.

[0029] The control unit 110 operates based on a program (not shown) stored in the storage unit 120, and executes the functions of the cleaning process control unit 111, the gas sensor control unit 112, the frequency component extraction unit 113, and the transmission unit 114, as shown in Fig. 3. The programs are not limited to being stored in the storage unit 120, and may be stored in, for example, a ROM (not shown) in the controller 100. The cleaning process control unit 111, the gas sensor control unit 112, the frequency component extraction unit 113, and the transmission unit 114 will be described in detail later.

[0030] The storage unit 120 temporarily stores detection data detected by the gas sensor 12 and extracted data of frequency components of the user's breath extracted by the frequency component extraction unit 113. The storage unit 120 may also store programs for each function executed by the control unit 110, as described above. The extracted data and programs stored in the storage unit 120 may be configured as areas physically or logically separated within one storage device. Alternatively, the storage units 120 for each data may be provided in multiple physically different storage devices.

[0031] The communication IF 130 is an interface for communicating with the terminal 20 via a wired and / or wireless network.

[0032] The input / output IF140 is an interface with the cleaning unit 11, the switch 13, the gas sensor 12, and the display unit 14, which are provided in the oral irrigator 10. The control unit 110 acquires the state of the discharge ON / OFF switch pressed by the user via the input / output IF140. The control unit 110 also acquires the state of the switch 13 pressed by the user via the input / output IF140. Furthermore, the control unit 110 controls the gas sensor 12 according to the state of the switch 13. Details of the control of the cleaning unit 11 and the gas sensor 12 by the control unit 110 will be described later. The control state of the oral irrigator 10 is displayed on the display unit 14 according to the control state of the control unit 110. Specifically, a lamp on the display unit 14 indicates whether the oral irrigator 10 is in a standby mode, an oral cleaning mode, or an exhaled breath collection mode.

[0033] Next, each function of the control unit 110 will be described in detail.

[0034] The cleaning process control unit 111 controls the on / off of the oral cavity cleaning mode by discharging a water flow from the nozzle of the cleaning unit 11. That is, the cleaning process control unit 111 controls the cleaning process of the oral cavity by the cleaning unit 11 for cleaning the oral cavity. Specifically, the cleaning process control unit 111 controls the discharge of the water flow from the nozzle of the cleaning unit 11 according to the state of the discharge ON / OFF switch. In this embodiment, when the user turns on the main power supply (not shown), the oral cavity cleaning mode is started in the ON state. Also, when the user turns on the discharge ON / OFF switch while the oral cavity cleaning mode is on, the discharge is turned on and the water flow is discharged from the nozzle. Also, when the user presses the discharge ON / OFF switch again, the discharge is turned off and the discharge of the water flow from the nozzle stops.

[0035] The gas sensor control unit 112 controls the on / off of an exhaled breath collection mode in which the gas sensor 12 collects the user's exhaled breath. Specifically, the gas sensor control unit 112 turns on the exhaled breath collection mode when the collection of the user's exhaled breath by the gas sensor 12 is enabled according to the state of the switch 13. When the exhaled breath collection mode is on, the gas sensor 12 is enabled, and the collected user's exhaled breath from the nozzle of the cleaning unit 11 is sensed. In addition, the gas sensor control unit 112 turns off the exhaled breath collection mode when the collection of the user's exhaled breath by the gas sensor 12 is disabled. In this specification, data detected (sensed) by the gas sensor 12 is referred to as detection data. The detection data detected by the gas sensor 12 is stored in the storage unit 120. The detection data is stored in the storage unit 120 together with the time of detection. The gas sensor control unit 112 corresponds to an intraoral information acquisition unit.

[0036] The frequency component extraction unit 113 extracts frequency components (component information) of the detection data for the detected breath of the user, and stores the frequency components in the storage unit 120. Specifically, a component of a predetermined frequency is obtained as shown in FIG. 4. In the example shown in FIG. 4, it is shown that the frequencies of the first waveform 113a and the second waveform 113b increase for the breath exhaled by the user between time T1 and time T2. The frequency component extraction unit 113 extracts breath components showing a specific frequency in this manner. In this embodiment, for example, the first waveform 113a shows the time response characteristic of methyl mercaptan, and the second waveform 113b shows the time response characteristic of hydrogen sulfide. In this specification, data (component information) related to the frequency components extracted in the frequency component extraction unit 113 is called extracted data. The frequency component extraction unit 113 corresponds to a component information extraction unit.

[0037] The transmission unit 114 transmits the extracted data relating to the frequency components extracted by the frequency component extraction unit 113 to the terminal 20 via the communication IF .

[0038] (Functional configuration of terminal 20) Next, the functions of the terminal 20 will be described using the functional block diagram shown in Fig. 2. The terminal 20 is configured, for example, as a smartphone equipped with a general computer 200, and is usually operated by a user who operates the oral irrigator 10. The terminal 20 may be configured as a mobile device such as a tablet or a notebook computer. As shown in Fig. 2, the computer 200 of the terminal 20 is configured to include a control unit 210, a storage unit 220, a communication IF 230, and an input / output IF 240.

[0039] The terminal 20 displays an image for advice on cleaning the oral cavity on the display device 21. FIG. 5 shows an example of an image displayed on the terminal 20. The user cleans the oral cavity by following the screen (guide) shown in FIG. 5. In the example shown in FIG. 5, the image shows the teeth to which the water flow from the nozzle should be applied by moving the position of the shaded part (highlight) as shown by tooth 21b in the direction of the arrow 21a in sequence. In addition, the control unit 210 of the terminal 20 causes the display device 21 to display the location where the breath is to be collected in the breath collection mode. For example, the control unit 210 of the terminal 20 displays a message such as "Point the nozzle between the inside of the specified tooth and the gums and blow in," and the user points the nozzle at the specified location according to the displayed content and blows in the breath collection mode. The control unit 210 of the terminal 20 stores the time when the specified location in the breath collection mode was specified in the storage unit 220 for each specified location. In addition, the designation of the designated location (tooth) in the breath collection mode does not limit this embodiment, and the periodontal disease determination system 1 may be configured to collect breath from the entire oral cavity rather than collecting breath from each designated location (tooth) in the breath collection mode.

[0040] Furthermore, the terminal 20 may operate based on a program (not shown) stored in the storage unit 220 and execute a predetermined application. In this case, for example, the user may input or select a predetermined mode for the functions of the oral irrigator 10 displayed on the display device 21 via the display device 21 functioning as a touch panel. For example, the oral irrigator 10 may be configured to allow the user to select the strength of the water flow (water pressure), etc.

[0041] In addition, the control unit 210 of the terminal 20 receives, from the oral irrigator 10, extracted data of frequency components extracted from the detection data of the user's exhaled breath, and stores the same in the memory unit 220.

[0042] The control unit 210 of the terminal 20 includes an estimation unit 215 as a function. The estimation unit 215 estimates the degree of periodontal disease based on frequency components. In this embodiment, the estimation unit 215 performs estimation based on a graph in which the principal components are represented by two axes, principal component A and principal component B, as shown in FIG. 6. In this embodiment, principal component A indicates the value of the frequency component of methyl mercaptan, and principal component B indicates the value of the frequency component of hydrogen sulfide. For example, the estimation unit 215 plots the maximum value of the frequency of principal component A on the graph by applying the value on the horizontal axis and the maximum value of the frequency of principal component B on the vertical axis.

[0043] For example, when the value of the frequency component is included in the mild region 114a, the moderate region 114b, or the severe region 114c, the estimation unit 215 estimates that the periodontal disease is mild, moderate, or severe. The mild, moderate, and severe regions shown in FIG. 6 are grouped based on a clustering method such as the K-means method using frequency components of breath detection data collected in advance from multiple periodontal disease patients as samples. This makes it possible to estimate the degree of periodontal disease more accurately than, for example, estimating the degree of periodontal disease based on the concentration of a specific component contained in the breath of a patient with periodontal disease. Note that the clustering method such as the K-means method does not limit the configuration of this embodiment, and for example, a hierarchical method such as the shortest distance method or Ward's method may be used as a grouping method.

[0044] In the first embodiment, the estimation unit 215 estimates the degree of periodontal disease for each designated location specified in the breath collection mode. That is, the control unit 210 of the terminal 20 compares the time when the designated location was specified in the breath collection mode with the time stored in the storage unit 220 for each designated location and the time provided in correspondence with the extracted data for each designated location, and associates the extracted data with the designated location.

[0045] The terminal 20 displays the estimated result of the degree of periodontal disease on the display device 21. FIG. 7 shows an example of a screen displaying the estimated result of the degree of periodontal disease. As shown in the designated positions 21a to 21g in FIG. 7, the places with a high risk of periodontal disease are displayed in a color such as red. The estimated result of the degree of periodontal disease displayed on the display device 21 may have a different color density depending on the degree of mild, moderate, and severe. Alternatively, the estimated result may be displayed in a different pattern depending on the degree of mild, moderate, and severe. In the first embodiment, as shown in FIG. 7, the estimated result is displayed for each designated position (tooth) designated in the breath collection mode. In the first embodiment, when measurement for each tooth is not performed in the breath collection mode, for example, a display such as "Your risk of periodontal disease is high" may be displayed on the display device 21.

[0046] (Outline of the processing flow of the oral irrigator 10) Next, the process for determining periodontal disease (periodontal disease determination method) in the oral irrigator 10 equipped with the gas sensor 12 will be described based on the flowchart in Figure 8. The series of operations of the oral irrigator 10 shown in the flowchart in Figure 8 begins when the oral irrigator 10 is started, and ends when the power is turned off. In addition to being turned off, the process in the flowchart shown in Figure 8 also ends when an interrupt is issued to end the process. In the following description of the flowchart, the same content as that described above in the description of the oral irrigator 10 will be omitted or simplified.

[0047] In step S801, the cleaning process control unit 111 turns on the cleaning unit 11 to start cleaning the oral cavity. Specifically, the user presses the start switch (not shown) of the cleaning unit 11, and then the user presses the discharge ON / OFF switch of the nozzle. Then, the control unit 110 detects the pressing of the discharge ON / OFF switch and sends a control instruction to the cleaning process control unit 111, and oral cavity cleaning is started.

[0048] In step S802, the control unit 110 determines whether the oral cleaning has been completed. Specifically, the control unit 110 determines whether the oral cleaning has been completed by detecting whether the discharge ON / OFF switch has been pressed again by the user's operation to terminate the discharge. In step S802, if the control unit 110 determines that the oral cleaning has been completed (step S802: YES), the control unit 110 proceeds to step S803. On the other hand, in step S802, if the control unit 110 determines that the oral cleaning has not been completed (step S802: NO), the control unit 110 returns to step S802 and repeats the process of step S802. That is, the process of step S802 is repeated until the oral cleaning is completed, and the oral cavity is cleaned.

[0049] In step S803, the gas sensor control unit 112 controls the gas sensor 12 to obtain the breath detection data and store it in the storage unit 120. That is, the gas sensor control unit 112 controls the on / off of the breath collection mode in which the breath of the user is collected by the gas sensor 12. Specifically, the gas sensor control unit 112 turns on the breath collection mode when the gas sensor 12 is to enable the acquisition of the breath detection data of the user. When the breath collection mode is on, the gas sensor 12 is enabled and the collected breath of the user from the nozzle of the cleaning unit 11 is detected. In the breath collection mode, the user points the tip of the nozzle at a specified location and blows breath, following the guide displayed on the display unit 21 of the terminal 20. In addition, the gas sensor control unit 112 turns off the breath collection mode when the collection of the breath of the user by the gas sensor 12 is to be disabled. The on / off control of the breath collection mode is performed by the gas sensor control unit 112 depending on the state of the switch 13 pressed by the user.

[0050] The gas sensor control unit 112 controls the acquisition of detection data by acquiring detection data for each designated location in the breath sampling mode displayed on the display device 21 of the terminal 20. For example, in this embodiment, the user blows breath into each designated location designated on the display device 21 of the terminal 20, and detection data for each designated location is acquired. Alternatively, if the switch 13 can independently control the breath sampling mode, the user may press the switch 13 for each designated location designated on the display device 21 of the terminal 20 to acquire detection data for each designated location. The detection data for each designated location is stored in the storage unit 120 together with the detection time.

[0051] In step S804, the frequency component extraction unit 113 extracts extracted data of frequency components from the detection data of the collected breath of the user, and stores the extracted data in the storage unit 120. Specifically, the frequency component extraction unit 113 extracts a component of a predetermined frequency as shown in Fig. 4. In this embodiment, in the example shown in Fig. 4, for example, the frequency component of methyl mercaptan in the first waveform 113a is acquired, and the frequency component of hydrogen sulfide in the second waveform 113b is acquired. The extracted data is stored in the storage unit 120 in association with the time acquired at the time of detection of the detection data.

[0052] In step S805, the transmission unit 114 transmits the extracted data of the frequency components to the terminal 20 via the communication IF 130. After that, the process proceeds to step S806.

[0053] In step S806, the gas sensor control unit 112 turns off the gas sensor 12, ends the breath collection mode, and the processing in the oral irrigator 10 ends.

[0054] In step S807, the terminal 20 receives the extracted data from the oral irrigator 10 via the communication IF 230.

[0055] In step S808, the estimation unit 215 of the terminal 20 estimates the degree of periodontal disease. Specifically, the degree of periodontal disease is estimated based on the extracted data of frequency components. In this embodiment, the estimation unit 215 estimates the degree of periodontal disease based on a graph in which the principal components are represented by two axes, principal component A and principal component B, as shown in Fig. 6. In the first embodiment, the estimation unit 215 estimates the degree of periodontal disease for each designated location designated in the breath sampling mode.

[0056] In step S809, the control unit 210 of the terminal 20 causes the display device 21 to display the estimation result of the degree of periodontal disease via the input / output IF 240. For example, in the first embodiment, the estimation result of the degree of periodontal disease as shown in Fig. 7 is displayed. In the first embodiment, as shown in Fig. 7, it is possible to display the estimation result for each designated location designated in the breath sampling mode.

[0057] As described above, the periodontal disease determination system 1 according to the first embodiment includes the gas sensor 12 in the oral irrigator 10, and enables the user to detect the breath of the user immediately after performing oral irrigation using the gas sensor 12. This reduces the influence of noise odors caused by food residues, and makes it possible to appropriately determine odors caused by periodontal disease.

[0058] Moreover, the periodontal disease determination system 1 according to the first embodiment includes a frequency component extraction unit 113 that extracts frequency components of exhaled breath based on components of detection data detected by the gas sensor 12, and a transmission unit 114 that transmits extracted data relating to the frequency components to the terminal 20. As a result, the periodontal disease determination system 1 transmits extracted data in which only necessary frequency components are extracted from the detection data detected by the gas sensor 12 to the terminal 20, thereby reducing the amount of data transmitted to the terminal 20 and the amount of data in the estimation process at the terminal 20.

[0059] Furthermore, the periodontal disease determination system 1 according to the first embodiment estimates the degree of periodontal disease based on correlations of extracted data extracted from frequency components based on data that has been clustered (grouped) in advance. For example, it is possible to estimate the degree of periodontal disease more accurately than estimating the degree of periodontal disease based on the concentration of a specific component contained in the breath of a patient with periodontal disease.

[0060] Moreover, the gas sensor 12 of the oral irrigator 10 according to the first embodiment is composed of a quartz crystal resonator gas sensor. A quartz crystal resonator gas sensor can be realized with lower power consumption than a semiconductor gas sensor. This enables the oral irrigator 10 to collect breath from the oral cavity with lower power consumption. Furthermore, since a quartz crystal resonator gas sensor is smaller than a semiconductor gas sensor, the oral irrigator 10 can be made smaller.

[0061] Moreover, the oral irrigator 10 according to the first embodiment further includes a filter for adjusting the humidity of the gas flowing into the gas sensor 12. This filter makes it possible to remove moisture contained in the collected breath of the user, thereby reducing the effect of the moisture contained in the breath on the gas sensor 12.

[0062] Second Embodiment As described above, one specific embodiment has been described, but the above-mentioned embodiment is merely an example and is not intended to limit the embodiments. For example, in the above-mentioned embodiment, a configuration is shown in which the main components of the user's breath extracted by the oral irrigator 10 are used to estimate the degree of periodontal disease in the terminal 20. Here, a configuration different from that of the first embodiment is described for a periodontal disease determination device 2 according to a second embodiment that estimates periodontal disease in the oral irrigator 10.

[0063] 9 is a schematic diagram showing an outline of a periodontal disease determination device 2 in the second embodiment. As shown in FIG. 9, the periodontal disease determination device 2 includes a cleaning unit 11, a gas sensor 12, an air inlet 16, and a display device 21.

[0064] Fig. 10 shows a block diagram of the periodontal disease determination device 2 in the second embodiment. Fig. 11 is a block diagram showing the functional configuration of a control unit 110 of the periodontal disease determination device 2. As shown in Fig. 11, the control unit 110 of the periodontal disease determination device 2 differs from the configuration of the oral irrigator 10 in the first embodiment in that it includes an estimation unit 115.

[0065] In other words, the periodontal disease assessment device 2 in the second embodiment is configured to include an estimation unit 115, thereby enabling the periodontal disease assessment device 2 to perform oral cleaning, collection of exhaled breath, extraction of frequency components of the exhaled breath, and estimation of the degree of periodontal disease.

[0066] In the periodontal disease assessment device 2, a user cleans the inside of the oral cavity using the cleaning unit 11. In the second embodiment, the cleaning unit 11 is configured with a toothbrush, that is, the oral irrigator 10 functions as an electric toothbrush.

[0067] After cleaning the inside of the oral cavity with the periodontal disease assessment device 2, the user blows into the blowing port 16, so that the periodontal disease assessment device 2 collects the breath of the user. Components of the collected breath of the user are detected by the gas sensor 12.

[0068] In the second embodiment, similarly to the first embodiment, the frequency components of the detected breath of the user are extracted by the frequency component extraction unit 113. Then, in the second embodiment, the estimation unit 115 estimates the degree of periodontal disease based on the extracted frequency components.

[0069] Moreover, in the periodontal disease determination device 2 in the second embodiment, the estimated degree of periodontal disease is displayed via a display device 21. For example, the display device 21 of the periodontal disease determination device 2 is composed of a liquid crystal panel, an LED lamp, or the like. The user can recognize the degree of periodontal disease based on the periodontal disease estimation result displayed on the display device 21.

[0070] Next, the process for periodontal disease judgment by the periodontal disease judgment device 2 in the second embodiment (periodontal disease judgment method) will be described based on the flowchart in Fig. 12. The series of operations of the periodontal disease judgment device 2 shown in the flowchart in Fig. 12 starts when the periodontal disease judgment device 2 is started, and ends when the power is turned off. The process in the flowchart shown in Fig. 12 also ends when the power is turned off or when an interrupt is issued to end the process. In the following description of the flowchart, the same content as that described in the description of the periodontal disease judgment device 2 will be omitted or simplified.

[0071] In step S1201, the cleaning process control unit 111 turns on the cleaning unit 11 to start cleaning the oral cavity. Specifically, the user presses the start switch (not shown) of the cleaning unit 11, and then the user presses the discharge ON / OFF switch of the nozzle. Then, the control unit 110 detects the pressing of the discharge ON / OFF switch and sends a control instruction to the cleaning process control unit 111, and the oral cavity cleaning mode is started.

[0072] In step S1202, the control unit 110 determines whether the oral cleaning has been completed. Specifically, the control unit 110 determines whether the oral cleaning has been completed by detecting whether the discharge ON / OFF switch has been pressed again by the user's operation to terminate the discharge. In step S1202, if the control unit 110 determines that the oral cleaning has been completed (step S1202: YES), the control unit 110 proceeds to step S1203. On the other hand, in step S1202, if the control unit 110 determines that the oral cleaning has not been completed (step S1202: NO), the control unit 110 returns to step S1202 and repeats the process of step S1202. That is, the process of step S1202 is repeated until the oral cleaning is completed, and the oral cavity is cleaned.

[0073] In step S1203, the gas sensor control unit 112 controls the gas sensor 12 to obtain the breath detection data and store it in the storage unit 120. That is, the gas sensor control unit 112 controls the on / off of the breath collection mode in which the breath of the user is collected by the gas sensor 12. Specifically, the gas sensor control unit 112 turns on the breath collection mode when the collection of the breath of the user by the gas sensor 12 is enabled. When the breath collection mode is on, the gas sensor 12 is enabled and the collected breath of the user from the air inlet 16 is detected. Moreover, when the gas sensor control unit 112 disables the collection of the breath of the user by the gas sensor 12, the gas sensor control unit 112 turns off the breath collection mode. The on / off control of the breath collection mode is performed by the gas sensor control unit 112 depending on the state of the switch 13 pressed by the user.

[0074] In step S1204, the frequency component extraction unit 113 extracts frequency component extraction data from the collected breath detection data of the user, and stores the extracted data in the storage unit 120. Specifically, a component of a predetermined frequency as shown in FIG.

[0075] In step S1205, the gas sensor control unit 112 turns off the gas sensor 12, and the breath sampling mode ends.

[0076] In step S1206, the estimation unit 115 estimates the degree of periodontal disease. Specifically, the estimation unit 115 estimates the degree of periodontal disease based on the extracted data of the frequency components. In this embodiment, the estimation unit 115 estimates the degree of periodontal disease based on a graph in which the principal components are represented by two axes, principal component A and principal component B, as shown in FIG.

[0077] In step S1207, the control unit 110 causes the display device 21 via the input / output IF 140 to display the estimation result of the degree of periodontal disease.

[0078] The periodontal disease determination device 2 in the second embodiment may be capable of communicating with an external terminal via the communication IF 130. For example, the device may be provided with the terminal 20 in the first embodiment, and may perform oral cleaning and breath sampling according to a guide image in the oral cleaning mode or a guide image in the breath sampling mode shown in Fig. 5. In addition, the estimation result of the degree of periodontal disease estimated by the estimation unit 115 may be transmitted to the terminal 20 via the communication IF 130, and the estimation result may be displayed on the display device 21 of the terminal 20.

[0079] As described above, the periodontal disease determination device 2 in the second embodiment includes a frequency component extraction unit 113 inside the oral irrigator 10 that extracts frequency components of the exhaled breath based on components of detection data detected by the gas sensor 12. The periodontal disease determination device 2 also includes an estimation unit 115 inside the oral irrigator 10 that estimates the degree of periodontal disease of the user by determining components of the exhaled breath based on the frequency components. This makes it possible to estimate the degree of periodontal disease only by the periodontal disease determination device 2, without the need to transmit the extracted data to the terminal 20 in periodontal disease determination.

[0080] (Third embodiment) Next, a third embodiment will be described. In the following description, when the same reference numerals as those in the first and / or second embodiment are used, they indicate the same configuration as those in the first and / or second embodiment, and the preceding description will be referred to unless otherwise specified. Here, a configuration different from that of the first and / or second embodiment will be described for a periodontal disease determination system 3 according to a third embodiment, which estimates the degree of periodontal disease based on detection data of exhaled breath detected by a gas sensor 12. In the third embodiment, the server 40 corresponds to a terminal.

[0081] Fig. 13 is a diagram showing an overview of a periodontal disease determination system 3 in the third embodiment. As shown in Fig. 13, the periodontal disease determination system 3 in the third embodiment includes a server 40, and is configured so that an oral irrigator 10, a terminal 20, and the server 40 can communicate with each other via a network 30. Note that the configurations of the oral irrigator 10 and the terminal 20 are similar to those of the oral irrigator 10 and the terminal 20 in the first embodiment, and therefore a description thereof will be omitted here.

[0082] Fig. 14 is a block diagram showing the configuration of the server 40. The server 40 is configured with, for example, a general computer 400, and is operated by a user who operates the oral irrigator 10 or an administrator who comprehensively manages the user's health. The server 40 may be configured with a calculator such as a personal computer. As shown in Fig. 14, the computer 400 of the server 40 includes a control unit 410, a storage unit 420, a communication IF 430, and an input / output IF 440.

[0083] The server 40 may operate based on a program (not shown) stored in the storage unit 420 and execute a predetermined application.

[0084] Furthermore, the control unit 410 of the server 40 receives the detection data of the breath of the user transmitted from the oral irrigator 10 and stores it in the memory unit 420. The control unit 410 also includes an estimation unit 415 as a function, which estimates the degree of periodontal disease based on the detection data. In the third embodiment, the estimation unit 415 estimates the degree of periodontal disease by pattern recognition of the frequency tendency indicated by the detection data and the frequency tendency of the breath collected from the periodontal disease patient. In this embodiment, the frequency tendency of the breath collected from the periodontal disease patient is stored in advance in the memory unit 420 as a medical history DB (database) of the periodontal disease patient (not shown).

[0085] Next, the process related to periodontal disease determination (periodontal disease determination method) of the periodontal disease determination system 3 in the third embodiment will be described based on the flowchart in Fig. 15. The series of operations of the periodontal disease determination system 3 shown in the flowchart in Fig. 15 starts when the oral irrigator 10 is started, and ends when the power is turned off. The process in the flowchart shown in Fig. 15 also ends when an interrupt is issued to end the process, in addition to when the power is turned off. In the following description of the flowchart, the same content as that described in the description of the periodontal disease determination system 3 will be omitted or simplified.

[0086] In step S1501, the cleaning process control unit 111 turns on the cleaning unit 11 to start cleaning the oral cavity. Specifically, the user presses the start switch (not shown) of the cleaning unit 11, and then the user presses the discharge ON / OFF switch of the nozzle. Then, the control unit 110 detects the pressing of the discharge ON / OFF switch and sends a control instruction to the cleaning process control unit 111, and the oral cavity cleaning mode is started.

[0087] In step S1502, the control unit 110 determines whether the oral cleaning has been completed. Specifically, the control unit 110 determines whether the oral cleaning has been completed by detecting whether the discharge ON / OFF switch has been pressed again by the user's operation to terminate the discharge. In step S1502, if the control unit 110 determines that the oral cleaning has been completed (step S1502: YES), the control unit 110 proceeds to step S1503. On the other hand, in step S1502, if the control unit 110 determines that the oral cleaning has not been completed (step S1502: NO), the control unit 110 returns to step S1502 and repeats the process of step S1502. That is, the process of step S1502 is repeated until the oral cleaning is completed, and the oral cavity is cleaned.

[0088] In step S1503, the gas sensor control unit 112 controls the gas sensor 12 to obtain the breath detection data and store it in the storage unit 120. That is, the gas sensor control unit 112 controls the on / off of the breath collection mode in which the breath of the user is collected by the gas sensor 12. Specifically, the gas sensor control unit 112 turns on the breath collection mode when the gas sensor 12 is to enable the acquisition of the breath detection data of the user. When the breath collection mode is on, the gas sensor 12 is enabled and the collected breath of the user from the nozzle of the cleaning unit 11 is detected. In the breath collection mode, the user points the tip of the nozzle at a specified location and blows breath, following the guide displayed on the display unit 21 of the terminal 20. In addition, the gas sensor control unit 112 turns off the breath collection mode when the collection of the breath of the user by the gas sensor 12 is to be disabled. The on / off control of the breath collection mode is performed by the gas sensor control unit 112 depending on the state of the switch 13 pressed by the user.

[0089] In step S1504, the transmission unit 114 transmits the detection data detected by the gas sensor 12 to the server 40 via the communication IF 130. After that, the process proceeds to step S1505.

[0090] In step S1505, the gas sensor control unit 112 turns off the gas sensor 12, ends the breath collection mode, and the processing in the oral irrigator 10 ends.

[0091] In step S1506, the control unit 410 of the server 40 receives the detection data from the oral irrigator 10 via the communication IF 430.

[0092] In step S1507, the estimation unit 415 of the server 40 estimates the degree of periodontal disease based on the received detection data. Specifically, the estimation unit 415 estimates the degree of periodontal disease by pattern recognition of the frequency tendency indicated by the detection data and the frequency tendency of the breath collected from the periodontal disease patient.

[0093] In step S1508, the control unit 410 of the server 40 causes a display connected to the server 40 to display the estimation result of the degree of periodontal disease via the input / output IF 440. The control unit 410 of the server 40 may also send the estimation result of the degree of periodontal disease to the terminal 20 via the communication IF 430, and cause the display device 21 of the terminal 20 to display the estimation result of the degree of periodontal disease.

[0094] As described above, the periodontal disease determination system 3 according to the third embodiment transmits detection data of the breath detected by the gas sensor 12 to the server 40, and the estimation unit 415 of the server 40 estimates the degree of periodontal disease based on the detection data. This makes it possible to determine the components of the breath based on detection data that is not limited to a specific component, and makes it possible to more accurately estimate the degree of periodontal disease.

[0095] (Other embodiments) Although the present embodiment has been described above, the embodiment is not limited to these, and various modifications are possible within the scope of the gist of the embodiment. It is also possible to combine a part or all of the various embodiments to form a new embodiment. In other words, since the above-mentioned embodiment is intended to illustrate the technology in this disclosure, various modifications, substitutions, additions, omissions, etc. can be made within the scope of the claims or their equivalents.

[0096] In the above-described third embodiment, the estimation unit 415 is configured to estimate the degree of periodontal disease by pattern recognition of the frequency tendency indicated by the detection data and the frequency tendency of the breath collected from the periodontal disease patient, but the embodiment is not limited thereto. For example, as shown in FIG. 16, the server 40 may include a learning unit 450 including a machine learning unit 453. The machine learning unit 453 learns the relationship between the learning detection data 421 and the degree of periodontal disease based on the learning detection data 421, which is the breath detection data of the user stored in advance in the storage unit 420, and the periodontal disease history DB 422, which stores the periodontal disease history data of the periodontal disease patient. By using the trained model trained by the machine learning unit 453 as the estimation unit 415, the estimation unit 415 functions as a classifier that outputs an estimation result of the degree of periodontal disease for the breath detection data. This enables the estimation unit 415 to more accurately estimate the degree of periodontal disease for the breath detection data of the user.

[0097] In the above-mentioned first and second embodiments, the frequency component extraction unit 113 extracts methyl mercaptan as one of the main components, and the estimation unit 215 or the estimation unit 115 estimates the degree of periodontal disease. However, the embodiment is not limited to this. For example, the frequency component extraction unit 113 may extract dimethyl sulfide as one of the main components, extract hydrogen sulfide as reference data, and determine the components of the breath based on the correlation between them. This makes it possible to estimate the degree of a visceral disease, for example.

[0098] Moreover, the periodontal disease determination system 1 in the above embodiment has been shown to have a configuration including, as the intraoral information acquisition unit, the gas sensor control unit 112 that controls the on / off of the gas sensor 12 that detects the user's breath. Moreover, the periodontal disease determination system 1 has been shown to have, as the component information extraction unit, the frequency component extraction unit 113 that extracts the frequency component of the breath based on the component of the detection data detected by the gas sensor 12. However, the periodontal disease determination system 1 in the above embodiment is not limited to these configurations. For example, the intraoral information acquisition unit may be configured to acquire an image of the oral cavity by a camera. Furthermore, the component information extraction unit may be configured to extract a main component (principal component) of the image of the oral cavity. This makes it possible for the estimation unit to determine the component of the image based on the extraction data extracted from the component of the image of the oral cavity transmitted from the oral irrigator 10, and estimate the degree of the user's periodontal disease.

[0099] The scope of this embodiment includes a computer program (periodontal disease determination program) for causing a computer to execute the above-mentioned periodontal disease determination method and a computer-readable recording medium on which the program is recorded. Any type of computer-readable recording medium may be used. The above-mentioned computer program is not limited to one recorded on the above-mentioned recording medium, and may be one transmitted via a telecommunication line, a wireless or wired communication line, a network such as the Internet, or the like.
