Description

  The present invention is an invention related to a technique for estimating information related to a user's blood components from gas components that are generated at the time of defecation.

  In recent years, lifestyle-related diseases caused by meals and lifestyle habits are increasing. Western lifestyles such as high calories and fat in particular are the cause of the development of hyperlipidemia, and are known to be risk factors for arteriosclerotic diseases, one of the three major lifestyle diseases. In order to prevent lifestyle-related diseases, it is necessary to review diet and lifestyle habits and link them to health behavior. In reviewing meals and lifestyle habits, information on lipid metabolism in blood components, that is, information on total cholesterol, LDL cholesterol, HDL cholesterol, neutral fat and the like in blood is useful information.

Blood sampling is one of the conventional methods for obtaining information on lipid metabolism in blood components. The user can obtain information on lipid metabolism in blood components by receiving a group medical examination or collecting blood in a hospital.
Although blood collection is an invasive technique, non-invasive techniques for collecting information about lipid metabolism in blood components are to irradiate the living body with light, receive transmitted light and reflected light, and analyze it. There is something to do. (For example, refer to Patent Document 1).

  Blood collection is an invasive technique that involves mental and physical pain. In addition, since blood can be collected only by qualified persons having specialized knowledge and skills, the user needs to undergo mass screening or examination at a hospital and cannot frequently obtain information on lipid metabolism in blood components. On the other hand, the non-invasive technique for collecting information on lipid metabolism in blood components described in Patent Document 1 requires expensive and large devices for measurement and data processing, and is easily used by users on a daily basis. It is not possible.

  Patent Document 2 is a method for calculating and displaying information related to lipid metabolism in blood components from user biometric information that has been input and stored in advance and measured bioimpedance information. It is the information guessed. The concentration of lipids in blood components is affected not only by the amount of meals, but also by the quality of the diet and the ability of individuals to digest and absorb, so it is wrong for people who are not obese but have a high amount of lipids in the blood May provide information.

  The present invention has been made to solve the above problems, and an object of the present invention is to obtain and provide information on lipid metabolism in blood easily and non-invasively.

  In order to solve the above-described problems, the health condition measuring apparatus of the present invention includes a gas sensor that measures the concentration of a predetermined component in a gas that is present in the toilet bowl of a toilet bowl, and the aforementioned predetermined component concentration and the user's blood. A storage unit storing correspondence data with information on lipid metabolism in the component, and a predetermined component concentration measured by the gas sensor is applied to the correspondence data, and information on lipid metabolism in the blood component of the user is And a control unit that selects from corresponding data.

  The health condition measuring method of the present invention measures the concentration of a predetermined component in a gas that is coexisting during defecation present in a toilet bowl of a toilet using a gas sensor, and then, in advance, the concentration of the predetermined component and the blood component of the user The correspondence data is called from the storage unit storing the correspondence data with the lipid metabolism information in the storage unit, and the control unit applies the predetermined component concentration measured by the gas sensor to the correspondence data, and the blood component of the user It is characterized in that information on lipid metabolism in the medium is selected from the correspondence data.

  According to the present invention, information on lipid metabolism in blood components can be easily obtained on a daily basis without depending on group medical examinations. Moreover, since the components in the gas that are generated at the time of defecation are used, it can be provided as information reflecting the daily eating habits of the user.

(A)-(c) is a figure which shows the procedure for estimating the information regarding the lipid metabolism of blood from the detected gas concentration which concerns on this invention. It is an external view (partial fluoroscopy) which shows an example of the health condition measuring apparatus and alerting | reporting apparatus (mounted in the sanitary washing toilet seat apparatus) of this invention. The figure which shows the procedure of the health condition measuring method using the health condition measuring apparatus and alerting device (installed in the sanitary washing toilet seat apparatus) of this invention.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the accompanying drawings. FIGS. 1A to 1C are examples showing a procedure for obtaining information on lipid metabolism in blood from detected gas concentrations, and FIG. 1A shows the concentration of carbon dioxide in gas generated during defecation. It is a graph which shows the example which measured V with the gas sensor. The horizontal axis represents the time required for defecation, t1 is when defecation starts, and t2 is when defecation ends. The defecation time here is the time when the signal value of the output of the gas sensor is stored. The vertical axis represents the carbon dioxide concentration (signal value of sensor output). The gas sensor may be anything as long as it can detect at least the highest concentration (peak value: Vp value). Here, the maximum concentration (peak value: Vp value) is a value obtained by subtracting the minimum value Vb of the carbon dioxide concentration from the maximum value Vmax of the carbon dioxide concentration. Since the Vp value appears when the amount of defecation is the largest, if the gas concentration at this time is adopted, a more accurate carbon dioxide concentration (signal value of sensor output) can be estimated. Data on carbon dioxide concentration (signal value of sensor output) can be prevented by erasing the concentration before this device is used next time or by transferring to another storage unit. can do.

  FIG. 1B is a diagram showing the relationship between the maximum concentration of carbon dioxide (Vp value) and information on lipid metabolism in blood. For 12 healthy adults (subjects) who do not have a disease requiring treatment, blood lipid metabolism items, that is, neutral fat, LDL cholesterol, and HDL cholesterol levels are examined. However, the maximum concentration of carbon dioxide generated at the time of defecation is divided into the test subject group (x) whose test values are outside the standard value and the test subject group (y) whose test values are within the standard values for all items. It is the figure which plotted the measured value (individual average value) measured with the gas sensor.

  FIG.1 (c) is the figure which matched the information regarding the lipid metabolism in blood which adapts according to the highest concentration (Vp value) of the carbon dioxide shown by FIG.1 (b). For example, the maximum concentration (Vp1 value) of carbon dioxide obtained by a certain measurement is equal to or less than a certain concentration (Vd) (region (A): 300 ppm or less in the figure) or more than a certain concentration (Vu) (in the figure). In the case of the region (C): 600 ppm or more), the information that “one or more items relating to lipid metabolism in the blood deviate from the standard value” is associated, and the maximum concentration of carbon dioxide (Vp1 value) ) Falls within a certain concentration range (region B in the figure: range from Vd to Vu, a range greater than 300 ppm and less than 600 ppm), it is said that “all items related to lipid metabolism in the blood are within the standard value”. Information is associated.

  1 (a) to 1 (c), information on lipid metabolism in blood corresponding to the maximum concentration (Vp value) of carbon dioxide can be obtained. By displaying information on lipid metabolism in the obtained blood, the user can easily obtain information on blood lipid metabolism in a non-invasive manner simply by defecation. Furthermore, by storing the maximum concentration (Vp value) of carbon dioxide in the storage unit and calling it up appropriately to perform data processing over time, it is possible to provide information that takes into account the food quality information for a certain period. Yes, you can manage your daily health.

  The health condition measuring device and the notification device of the present invention can be built in, for example, a sanitary washing toilet seat device attached to a Western-style toilet, can be built into a toilet seat of a Western-style toilet, or can be retrofitted to an existing Western-style toilet. It is also possible to make it portable so that information on lipid metabolism in blood components can be easily obtained regardless of where the toilet enters.

  FIG. 2 is an external view (partial perspective) showing an example of a sanitary washing toilet seat device attached to a Western-style toilet equipped with the health condition notifying device M of the present invention. A deodorizing fan exhaust passage 4 is installed using a space provided between a sanitary washing toilet seat device 2 having a built-in health condition measuring device L attached to the toilet 1 and the top of the toilet bowl 3 periphery. A carbon dioxide sensor 5 is attached in the exhaust passage 4 for the deodorizing fan. In addition, the storage unit 6 and the control unit 7 are integrated and incorporated in the rear portion of the sanitary washing toilet seat device 2, and further, information on blood lipid metabolism associated with the highest carbon dioxide concentration (Vp value) is reported. The notification unit 8 is incorporated in the operation unit 9 of the sanitary washing toilet seat device.

  That is, the configuration of the health condition measurement device L includes the carbon dioxide sensor 5, the storage unit 6, and the control unit 7, and the configuration of the health condition notification device M includes the health condition measurement device L and the notification unit 8. Data exchange between the carbon dioxide sensor 5 and the control unit 7 is performed by connection, and data exchange between the control unit 7 and the notification unit 8 is performed by infrared rays.

  FIG. 3 is an example showing a procedure of a health condition measuring method using the health condition measuring device and the notification device (mounted on the sanitary washing toilet seat device) of the present invention. The operation of the user (hereinafter referred to as “user”) is displayed on the left side, and the processing performed by the sanitary washing toilet seat device (including the processing of the health condition measuring device and the notification device) is displayed on the right side.

  This figure will be described below. The user enters the toilet, defecates, and then leaves, but the toilet is equipped with the health condition measuring device and the notification device of the present invention, so before leaving the room, it relates to lipid metabolism in his blood. By displaying the information, it is possible to know the physical condition of the day, or to know the change in physical condition over time when continuously measuring.

  When the user enters the room, the entry is detected by the human body detection sensor. Then the gas sensor is turned on. When the human body detection sensor is not used, the user may manually turn on the health measuring device and the leaving device. When the user is seated, the seating sensor detects the seating, and the gas sensor starts recording and storage. The user may press the start switch of each sensor without using the seating sensor.

  The time at the start of gas sensor operation is t1, and the signal value (carbon dioxide concentration) of the gas sensor output corresponding to that time is called V1. The signal value (carbon dioxide concentration) of the gas sensor output is stored in the storage unit simultaneously with the gas sensor operation. Until the user starts and finishes defecation, the data Vx is detected at regular time intervals tx and written in the storage unit.

  After the defecation is completed, the user starts the buttocks cleaning. At this time, the sensor recording is terminated in conjunction with the washing button. The time t2 at the end of the defecation and the detection data V2 at that time of each sensor are stored. When considering that the washing button may be used before or during defecation, the user may manually terminate the storage without interlocking with the washing button.

  After the storage, the control unit searches for the maximum value Vmax of the carbon dioxide concentration in the range of t1 to t2. A value obtained by subtracting the minimum value Vb of the carbon dioxide concentration from the value of Vmax or Vmax is recorded in the storage unit as a measured value (peak value Vp).

  The control unit associates information related to lipid metabolism in blood corresponding to the peak value Vp based on the correspondence data as shown in FIG. 1C and writes the information in the storage unit. The notification unit notifies the user of the correspondence result written in the storage unit by display or the like.

  When the user leaves the seat, the seating sensor senses it. When the user leaves the room, the human body detection sensor detects the exit. The switch of the health condition measuring device is turned off when a sitting or leaving room is detected.

  In the present invention, there are the following reasons for using the predetermined component in the gas that is generated at the time of defecation. Dietary habits that increase neutral fat and cholesterol in blood components include high fat dietary habits and high calorie dietary habits. High-fat dietary habits tend to increase blood cholesterol, and high-calorie dietary habits tend to increase blood neutral fat. On the other hand, it is known that the type and amount of gas generated during defecation are affected by the amount and quality of the ingested meal, that is, the dietary habits. Among gases, hydrogen and carbon dioxide are produced in the process of digestion of indigestible polysaccharides such as dietary fiber and undigested carbohydrates by intestinal bacteria. It is said that the greater the amount of polysaccharides and undigested carbohydrates, the greater the amount produced.

  High-fat dietary habits are appropriate for the amount of food consumed, but they tend to occur at the time of defecation compared to non-high-fat dietary habits because they tend to consume less dietary fiber and carbohydrates There is a tendency for the amount of hydrogen and carbon dioxide in the gas to be small. On the other hand, the nutritional balance is appropriate in high-calorie dietary habits, but the amount of food consumed exceeds the appropriate amount, and the amount of undigested carbohydrates and indigestible polysaccharides used for intestinal bacteria is high. There is a relatively large tendency. That is, it is presumed that the amount of hydrogen or carbon dioxide in the gas that is generated at the time of defecation is larger than that in the case of taking an appropriate amount of meal. In this way, the concentration of neutral fat and cholesterol in blood components varies due to the influence of dietary habits, and at the same time, the amount of hydrogen and carbon dioxide in the gas that accompanies defecation also fluctuates. It is considered possible to associate the amount of hydrogen and carbon dioxide with information on the state of neutral fat and cholesterol in blood components, that is, information on lipid metabolism in blood components.

  As described above, information on lipid metabolism in blood components is useful information when reviewing diet and lifestyle habits, but information on lipid metabolism in blood components is regularly checked in daily life. It is very difficult to do. Therefore, a health condition measurement device and a notification device that can easily and easily know information on lipid metabolism in blood components reflecting dietary habits without any load during daily defecation are useful.

  According to this example, information on lipid metabolism in blood components can be easily obtained on a daily basis without relying on group medical examinations. Moreover, since the components in the gas that are generated at the time of defecation are used, it can be provided as information reflecting the daily eating habits of the user.
