As shown in FIG. 1A, the power connector 2 is arranged on the back surface of the main body 15 and corresponds to the connector shape of the AC power cable. It has a shape.

  By connecting a connector of an AC power cable connected to an external AC power source (for example, 100 V) to the power connector 2, an AC voltage is input to a power supply board inside the main body. The power switch 3 is a switch for supplying a DC voltage to each electrical component inside the main body. As shown in FIG. 1 (d), the power switch 3 is arranged on the right side surface of the main body section 15, and is manually switched on / off. It is done. By turning this on, the DC voltage converted from the AC voltage in the power supply board is supplied to each electrical component inside the main body. At this time, a DC / DC converter is used to obtain a voltage value corresponding to the drive voltage of each electrical component.

  The operation key 4 is an example of an input unit, and is used to input subject information. In this example, as shown in FIG. 1 (c), when the subject's data is input to the subject information input screen arranged on the upper surface of the main body 15 and displayed on the display 7 as shown in FIG. 6. 10 numeric keys from 0 to 9, direction keys for selecting items for inputting values, and the like. Also included are an input completion key that is operated when input to the subject information input screen is completed, and a print key that is operated when data output to the display 7 is printed out.

  The operation key 4 is an example of a treatment method input means, and includes a menu of rehabilitation performed for the subject and / or a type of medicine used for the subject, a date of the rehabilitation, and / or The date of use of the drug is entered. In this example, it is used when selecting a rehabilitation menu or a medicine to be used on the treatment information input screen displayed on the display 7 as shown in FIG. Further, it is used when inputting a treatment date that is a date of implementation of a selected rehabilitation menu or a use date of a selected drug to be used. Specifically, a rehabilitation menu prepared as an option from a pull-down menu can be selected from the pull-down menu using the direction key, and similarly, a type of medicine prepared as an option can be selected from the pull-down menu. These pull-down menus also include the “None” option. By selecting “None” when rehabilitation is not performed or when no medicine is used, rehabilitation is performed in the treatment history DB described later. Menus and types of medicines are not remembered. This treatment information input screen displays a treatment date input field. When this screen is displayed, the date of the current day is entered as an initial value. This date can be changed by the operation key 4. For example, by selecting the rehabilitation menu performed three days ago and pressing the input completion key after entering the date three days ago, the date three days ago and the selected rehabilitation menu are stored in the treatment history DB described later. Will be.

  As shown in FIG. 1C, the flow sensor 5 is provided outside the main body, and one end of a differential pressure tube 16 composed of two tubes is connected and the other end is a differential pressure tube connection port of the main body 15. 6 and 6 are connected. The flow sensor 5 is detachable from the main body 15 and is housed in the holder of the main body 15 as shown in FIG. 1 (c) when not in use. Is done. In a state where the subject holds the flow sensor 5, the mouth includes a mouthpiece (not shown) attached to the blowing port 7 provided in the flow sensor 5, and breathes according to instructions from a doctor or a laboratory technician. As described later, various measurements are performed.

  A resistor is disposed in the flow tube of the flow sensor 5 (for example, a film-like resistor is disposed so as to block the gas flow in the flow tube), and when a gas flow is generated in the flow tube, A differential pressure is generated before and after the resistor. The pressure before and after the resistor is transmitted to the differential pressure tube connection ports 6 and 6 through the pressure ports arranged before and after the resistor and the differential pressure tube 16 connected to each of the pressure ports. It is the composition which becomes. That is, one of the two tubes constituting the differential pressure tube 16 transmits the pressure before the resistor to one tube connection port 6 connected to the tube, and the other connects the pressure after the resistor to the tube. Is transmitted to the other tube connection port 6. On the main body 15 side, the flow rate of the gas flowing through the flow tube (that is, the respiratory flow rate in this example) can be measured by detecting the differential pressure at the tube connection ports 6 and 6. Note that this type of flow sensor is a so-called differential pressure type and is widely used.

  The pressure sensor 10 outputs an analog signal (in this example, a voltage) proportional to the detected differential pressure. In this example, it is a semiconductor differential pressure sensor, which outputs a voltage proportional to the differential pressure detected by the differential pressure detection unit for detecting the differential pressure between the tube connection ports 6 and 6. An output terminal is provided. In this example, the voltage is output as an analog signal. However, the present invention is not limited to this, and a current proportional to the differential pressure detected as an analog signal may be output.

  The A / D converter 11 is for converting an analog electronic signal into a digital signal. In this example, it is a semiconductor A / D converter (ADC), and an analog signal output from the output terminal of the pressure sensor 10 (in this example, it may be a voltage but may be a current) can be processed by the CPU 12 described later. Is converted into a digital signal and output from the digital output terminal.

  The CPU 12 executes the processing program stored in the EEPROM 13 by using the RAM 14 as a work area, thereby controlling the operation of each connected component or receiving a signal from each component to perform various processes. Is what you do. In this example, a process for calculating a respiratory flow rate is performed based on a digital signal that is an output from the A / D converter 11 and indicates a value proportional to the differential pressure. This calculation is performed based on a relational expression between a differential pressure and a respiratory flow rate that are stored in advance. That is, the differential pressure is specified from the digital signal, and the specified differential pressure is input to the relational expression to calculate the respiratory flow rate. In this example, the respiratory volume is calculated by integrating the respiratory flow rate.

  The flow sensor 5, the differential pressure tube 16, the pressure sensor 10, the A / D converter 11, and the CPU 12, and the processing program executed by the CPU 12 are the measurement means for measuring the air flow velocity, pressure, flow rate, volume, and the like. It is an example, and other measurement methods may be used as long as they measure the respiratory flow rate and / or the respiratory volume. In this example, the breathing capacity (FVC), which is the amount of breath (air) that can be exhaled at a stretch by inhaling as much as possible by this measuring means, the breath exhaled during the first second of the forced vital capacity. (Air) volume per second (FEV1.0), breath capacity (VC) that is the amount of breath (air) that can be exhaled when inhaling slowly after breathing in slowly as much as possible Is measured. That is, the respiratory flow (FEV1.0) and the respiratory capacity (FVC, VC) are measured by the measuring means.

  The CPU 12 is an example of a calculation unit, and the measured value and / or input unit (operation key) measured by the measurement unit (flow sensor 5, differential pressure tube 16, pressure sensor 10, A / D converter 11, and CPU 12). Based on the information input in 4), the parameter value is calculated from a predetermined formula. In this example, FVC, FEV1.0, VC measured by measuring means (flow sensor 5, differential pressure tube 16, pressure sensor 10, A / D converter 11, and CPU 12) and input means (operation key 4) FEV1.0 / FVC, which is the first one-second rate, and FEV1.0 / FEV1.0, which is the second one-second rate, based on the gender, age, height, etc. of the subject input by Three of the predicted value and the VC / VC predicted value which is the vital capacity rate are calculated as parameter values. Note that the FEV1.0 predicted value and the VC predicted value are calculated based on a prediction formula stored in a prediction formula DB (database) described later.

  As shown in FIG. 3, the EEPROM 13 which is a non-volatile memory stores a prediction formula for calculating a predicted value of each item to be measured as prediction formula data. This prediction formula is used to calculate the predicted value of each item based on the gender, age, height, etc. of the subject input on the subject information input screen shown in FIG. 6 by the operation key 4 as the input means. In this example, as shown in FIG. 3, a VC predicted value that is a predicted value of VC, a formula for calculating a predicted value of FEV1.0 that is a predicted value of FEV1.0, and the like are stored. Has been.

  The EEPROM 13 is an example of staging classification storage means, and stores staging classification according to the parameter value. In this example, as shown in FIG. I remember it. This stage classification DB stores five categories of COPD stage classifications and ranges of parameter values corresponding to each of the sections. Parameter values calculated by the calculation means (CPU 12) (this book) In the example, the range of FEV1.0 / FVC, FEV1.0 / FEV1.0 predicted value) and the staging corresponding to each range (in this example, risk group, mild, moderate, severe, most severe) and Are stored in association with each other.

  The EEPROM 13 is an example of comment storage means, and stores comments according to parameter values. In this example, a comment DB is stored as shown in FIG. This comment DB stores a plurality of comments and a range of parameter values corresponding to each comment, and parameter values calculated by the CPU 12 as the calculation means (in this example, VC / VC prediction). Value, FEV1.0 / FVC) and a comment corresponding to each range (for example, “spirogram is normal”) are stored in association with each other.

  The EEPROM 13 is an example of a parameter value storage unit, and stores the parameter value calculated by the CPU 12 as the calculation unit in association with the measurement date of the measurement value used in calculating the parameter value. . In this example, as shown in FIG. 5, each subject is associated with a subject ID that can be specified individually, and the age, height, weight, sex, and smoking history that are subject information of the subject. (And the number of smokers), the measurement date of each measurement value, each measurement value (FVC, FEV1.0, VC), and the measurement value and subject information (gender, age, height) were calculated. Parameter values (FEV1.0 / FVC, FEV1.0 / FEV1.0 predicted value, VC / VC predicted value) are associated with each other and stored in the measurement history DB. That is, in the measurement history DB of FIG. 5, the subject information, the measurement date, the measurement value on the measurement date, and the parameter value on the measurement date are stored for each subject ID of each subject. .

  Further, the EEPROM 13 is an example of a treatment method storage means, and the rehabilitation menu and / or the kind of medicine input by the operation key 4 as the treatment method input means, the implementation date of the rehabilitation, and / or the use date of the medicine. Are stored in association with each other. In this example, as shown in FIG. 10, in the treatment history DB, the subject ID stored in the measurement history DB is stored, and is input on the treatment information input screen in association with the subject ID. The rehabilitation menu and / or the medicine to be used selected in the same screen are stored. In this treatment history DB and the above-described measurement history DB, information on the subject is stored in association with the subject ID of each subject, so which information is related to which subject. It can be identified.

  Here, the CPU 12 is an example of stage classification specifying means, and the stage classification corresponding to the parameter value calculated by the CPU 12 which is the calculation means is obtained from the stored contents of the stage classification storage means (stage stage DB of the EEPROM 13). It is something to identify. In this example, the FEV1.0 / FVC calculated by the CPU 12 and the stage classification corresponding to the calculated FEV1.0 / FEV1.0 predicted value are specified from the stage classification DB.

  Further, as shown in FIGS. 7 and 8 to be described later, the CPU 12 which is the stage classification specifying means is calculated in a graph displaying the range (condition) of each stage classification stored in the stage classification DB. It also performs processing for determining coordinates corresponding to the parameter values. That is, as shown in FIG. 7 and FIG. 8, by determining the coordinates corresponding to the parameter value if the range of each stage classification stored in the stage classification DB is shown to be visible, Since the stage classification to which the parameter value belongs is naturally specified, this process is a process for specifying the stage classification corresponding to the parameter value from the stored contents of the stage classification storage means.

  As described above, both the process for specifying the stage classification from the stage classification DB and the process for determining the coordinates in the graph in which the range of each stage classification stored in the stage classification DB is displayed are calculated. In this process, the stage classification corresponding to the parameter value is specified from the stored contents of the stage classification storage means.

  For example, when the FEV1.0 / FVC calculated by the CPU 12 is 0.5 and the calculated FEV1.0 / FEV1.0 predicted value is 0.25, FIG. ) In the stage classification DB shown in FIG. 5), the condition that FEV1.0 / FVC <0.7 & FEV1.0 / FEV1.0 predicted value <0.3 is satisfied, and the COPD stage classification “most severe” corresponds. It is specified as a period classification. 7 and 8, the horizontal axis is FEV1.0 / FVC, the vertical axis is FEV1.0 / FEV1.0 predicted value, and the graph shows the range of each stage classification. (0.5, 0.25) is determined as the coordinates corresponding to. This coordinate is within the range of FEV1.0 / FVC <0.7 & FEV1.0 / FEV1.0 predicted value <0.3 in the staging DB (that is, the range indicated as “most severe” on the graph), The “most severe” COPD staging is identified as the corresponding staging.

  The CPU 12 is an example of a comment specifying unit, and specifies a comment corresponding to the parameter value calculated by the CPU 12 which is a calculating unit from the stored content of the comment storing unit (the comment DB of the EEPROM 13). In this example, a process of specifying the VC / VC predicted value calculated by the CPU 12 and the comment corresponding to the calculated FEV1.0 / FVC from the stored contents of the comment DB shown in FIG. 4B is performed.

  For example, when the VC / VC predicted value calculated by the CPU 12 is 0.7 and the calculated FEV1.0 / FVC is 0.8, 0.65 ≦ VC in the comment DB. / VC predicted value <0.8 & FEV1.0 / FVC ≧ 0.7 The condition will be met, and from the comments in the comment DB, “There is a mild restrictive arousal disorder on the spirogram” as the corresponding comment Identified.

  The display 7 is an LCD display, and is provided on the upper surface of the main body 15 as shown in FIG. 1C. Output data is controlled from the CPU 12 via an LCD driver circuit (not shown), and predetermined data is obtained. Is output to the screen so as to be visible. The printer 8 is, for example, a thermal type (thermal type) printer, and outputs predetermined data on paper so that the CPU 12 can perform printing control via a thermal head driver.

  The display 7 and the printer 8 are examples of parameter value output means. As shown in FIGS. 7 and 8, the parameter values calculated by the CPU 12 as calculation means (in this example, FEV1.0 / FVC, FEV1,. 0 / FEV1.0 predicted value, VC / VC predicted value).

  The display 7 and the printer 8 are examples of staging classification output means. As shown in FIG. 7 and FIG. 8, the aspect (this book) can visually recognize the staging classification specified by the CPU 12 as staging classification specifying means. In the example, characters and graphs are output. In the examples of FIGS. 7 and 8, the horizontal axis is FEV1.0 / FVC, the vertical axis is FEV1.0 / FEV1.0 predicted value, and each risk group, mild, moderate, severe, and most severe stage classification Is plotted in coordinates corresponding to the parameter value (coordinates determined by the CPU 12 as the stage classification specifying means (in this example, (0.6, 0.46)). .

  In this graph, as shown in FIGS. 7 and 8, the range in which FEV1.0 / FVC is 0.7 or more is the risk group, FEV1.0 / FVC is less than 0.7, and FEV1. The range where 0 / FEV1.0 predicted value is 0.8 or more is mild, FEV1.0 / FVC is less than 0.7, and FEV1.0 / FEV1.0 predicted value is 0.5 or more and less than 0.8 Is moderate, FEV1.0 / FVC is less than 0.7, and FEV1.0 / FEV1.0 predicted value is 0.3 or more and less than 0.5, severe, FEV1.0 / FVC Is less than 0.7 and the FEV1.0 / FEV1.0 predicted value is less than 0.3 is displayed as the most severe range, and is determined by the CPU 12 as the staging classification specifying means. The coordinates (i.e. ★ coordinates) At a glance whether belonging to the class, it is possible to grasp. As shown in FIG. 7 and FIG. 8, “severe”, which is the stage classification identified by the CPU 12 as the stage classification specifying means, is output as characters at the bottom of this graph as the COPD stage classification. ing. This also makes it possible to grasp at a glance which stage classification the current parameter value belongs to.

  The display 7 and the printer 8 are examples of comment output means. As shown in FIGS. 7 and 8, the display 7 and the printer 8 output comments specified by the CPU 12 which is comment specifying means in a visible manner. In the example of FIGS. 7 and 8, “There is moderate mixed ventilation disorder on the spirogram” is displayed as a comment.

  Further, the display 7 and the printer 8 are examples of transition information output means, and the time-series transition of the parameter values stored in association with the measurement date in the measurement history DB (FIG. 5) of the EEPROM 13 as the parameter value storage means. Are output in a visually recognizable manner. In this example, as shown in FIG. 7B and FIG. 8, marks (□, ■, ☆, ★) corresponding to the parameter values of each measurement date are displayed on the graph, and each mark and each mark are displayed on the right side of the graph. The measurement date corresponding to the mark is displayed. Specifically, in the measurement history DB, □ is the place corresponding to the parameter value of 2003/4/8, and ■ is the place where the measurement date corresponds to the parameter value of 2003/5/2. ☆ is plotted at the location corresponding to the parameter value of 2003/6/5, and ★ is plotted at the location corresponding to the parameter value of 2003/7/1 on the same measurement date, so that the time-series transition of the parameter value can be grasped. It has become.

  Here, the transition information output means (display 7, printer 8) specifies the staging classification for each parameter value along with the time-series transition of the parameter values (FEV1.0 / FVC, FEV1.0 / FEV1.0 predicted value). The stage specified by the means (CPU 12) and / or the comment specified by the comment specifying means (CPU 12) is output in a visible manner. In this example, as described above, in the graph in which the risk group, mild, moderate, severe, and most severe stage classification ranges are displayed, each mark (in this example, □ , ■, ☆, ★) (FIGS. 7 and 8), the stage classification corresponding to each parameter value is output in a visually recognizable manner.

  Here, the display 7 and the printer 8 which are transition information output means include a rehabilitation menu and / or a kind of medicine stored in the treatment history DB in association with the implementation date and / or the use date that match the measurement date. And displayed in correspondence with the mark corresponding to the measurement date. Specifically, if a treatment date that matches the measurement date in the measurement history DB is stored in the treatment history DB, as shown in FIG. 11, the rehabilitation menu and / or the drug to be used corresponding to the treatment date is A mark corresponding to the measurement date is displayed next to the date of the measurement date. When there is no treatment date that matches the measurement date, it is determined whether there is a corresponding treatment date between the measurement date and the next measurement date. If there is a treatment date, the rehabilitation corresponding to the treatment date is performed. When the menu and / or the medicine to be used are displayed, the rehabilitation menu and / or the medicine to be used are not displayed when they do not exist. In addition, when the mark corresponding to each measurement date is displayed on the display 7, it is displayed one by one in order from the oldest corresponding measurement date at a predetermined interval (for example, 1 second). Therefore, marks are displayed in order of time series, and it is easy to grasp the transition of time series.

  The RS232C connector 9 is a terminal for transmitting and receiving data via an information terminal outside the respiratory function testing device 1 and a cable for RS232C. For example, when transmitting / receiving the stored contents of the measurement history DB to / from an external PC, the RS232C connector 9 and the RS232C connector on the PC side are connected by a cable for RS232C, and a predetermined operation (for example, the respiratory function test apparatus 1 side) is performed. The operation content of the measurement history DB is transmitted to the PC.

[2. Action of respiratory function test device)
Next, the effect | action of the said respiratory function test | inspection apparatus 1 is demonstrated using FIGS. When examining the respiratory function of the subject, if the subject is a new subject (that is, the subject who performs measurement for the first time), the doctor or laboratory technician can display the display as shown in D01 of FIG. Input age, height, weight, gender, and smoking history as subject information on the subject information input screen (hereinafter, simply referred to as input screen) shown in FIG. Let If the subject has a history of smoking, the number of smoking per day is also input and displayed on the input screen.

  Here, the date of the day is automatically displayed on the input screen as the measurement date, and the new subject ID is automatically displayed on the input screen as the subject ID. It has become. As shown in D02 of FIG. 6, after completing these input operations, by operating a predetermined key (for example, an input completion key) of the operation keys 4, each data displayed on the input screen is converted into a measurement history DB. Is stored in a waiting state for measurement.

  If the subject is not a new subject (that is, if the subject has a measurement history), the doctor or the laboratory technician can examine the subject's subject recorded in the medical record or the like. The ID is input by the operation key 4 (or the subject ID of the subject is selected from the subject ID stored in the measurement history DB) and displayed on the input screen. At this time, the age, height, weight, sex, and smoking history (and the number of smoking) stored in the measurement history DB in association with the subject ID are displayed on the input screen. Here, as the measurement date, the date of the current day is automatically displayed on the input screen. In this state, by operating a predetermined key (for example, the input completion key) of the operation key 4, the measurement date displayed on the input screen is associated with the displayed subject ID in the measurement history DB. It is memorized and enters a measurement waiting state.

  When the subject holds the flow sensor 5 in this state of waiting for measurement, includes the mouthpiece provided in the flow sensor 5 in his mouth, and breathes in accordance with the instructions of the doctor or laboratory technician, the above-described measurement means ( FVC, FEV1.0, VC are measured by the flow sensor 5, differential pressure tube 16, pressure sensor 10, A / D converter 11, CPU12), and FEV1.0 / FVC, FEV1.0 / are calculated by the calculation means (CPU12). The FEV1.0 predicted value and the VC / VC predicted value are calculated as parameter values. These measurement values and parameter values are stored in association with the subject ID and measurement date (date of the day) stored in the measurement history DB.

  After completion of the measurement, the CPU 12 as the staging classification specifying means selects the staging corresponding to the calculated parameter value (in this example, FEV1.0 / FVC, FEV1.0 / FEV1.0 predicted value). In addition to specifying from the classification DB, the coordinates of the parameter values in the graph showing the risk group, mild, moderate, severe, and most severe stage classification ranges are determined. Further, the CPU 12 as the comment specifying means specifies the comment corresponding to the calculated parameter value (in this example, FEV1.0 / FVC, VC / VC predicted value) from the stored content of the comment DB.

  Then, as shown in FIG. 7A, the display 7 displays a graph indicating the risk group, mild, moderate, severe, and most severe stage classification ranges. In this graph, ★ is displayed at the coordinates corresponding to the parameter values calculated this time (FEV1.0 / FVC, FEV1.0 / FEV1.0 predicted value). Also, below the graph, FEV1.0 / FVC, FEV1.0 / FEV1.0 predicted value, and VC / VC predicted value, which are parameter values calculated this time, are displayed. The stage classification ("severe" in this example) specified from the stored contents of the DB is displayed, and further below that, the comment specified from the stored contents of the comment DB ("moderate on the spirogram in this example" There is a mixed ventilation disorder ")" is displayed.

  In this way, the parameter value is calculated based on the measured respiratory flow and respiratory volume of the subject, and the stage classification of the subject is specified and output in a form that can be visually recognized by characters and graphs. Doctors and laboratory technicians can determine the staging classification at a glance, which reduces the determination load and helps prevent medical errors due to misunderstanding or oversight. In addition, since a comment about the subject is specified and output in a form that can be visually recognized by a character, a doctor or a laboratory technician can perform medical treatment with reference to the comment, and the burden of determination is reduced. It helps to prevent medical errors due to misunderstanding or oversight.

  If the subject is measuring before the current measurement, that is, if the subject is not a new subject, as shown in FIG. 7B, the measurement history DB A predetermined mark (in this example, □, ■, ☆ in the order of oldest measurement date) is further displayed at the coordinates corresponding to the past parameter values stored in, and each mark and the measurement date corresponding to each mark (respectively, 2003/4/8, 2003/5/2, 2003/6/5, and 2003/7/1) corresponding to the current ★ are displayed in the upper right of the graph. Here, each mark is displayed with a predetermined interval (in this example, 1 second) in order from the oldest corresponding measurement date. First, □ with a measurement date of 2003/4/8 is displayed. One second later, ■ is displayed with a measurement date of 2003/5/2, and one second later, the measurement date is 2003/6/5. ☆ is displayed, and after 1 second, ★ whose measurement date is 2003/7/1 is displayed. At this time, the date corresponding to each mark is also displayed in order from the oldest in synchronization with the mark.

  As described above, since the time-series transition of the parameter value is output in a form that can be visually recognized by the graph, it is useful for the doctor or the laboratory technician to grasp the transition of the parameter value and understand the course of the medical condition. In addition, the time-series transition of parameter values (□, ■, ☆, ★) is displayed on the graph showing the range of each staging category, so doctors and laboratory technicians can change It helps to understand the transition and understand the course of the disease. For example, in the example of Fig. 7 (b), it is understood that the staging is gradually changing from moderate (□, ■, ☆) to severe (★), and the disease state is getting worse. it can. Further, since each mark is displayed one by one in order from the oldest measurement date, there is an effect that it is possible to more easily grasp the time-series transition of parameter values.

  In order to print the data displayed on the display 7, the data displayed on the display 7 is displayed as shown in FIG. 8 by operating a predetermined key (for example, a print key) of the operation keys 4. Is output together with the subject information stored in the measurement history DB.

  Here, when the graph is output, for each measurement date stored in the measurement history DB in association with the subject ID, refer to the treatment date of the subject ID in the treatment history DB. If there is a treatment date that coincides with the measurement date, as shown in FIG. 11, the rehabilitation menu and / or the drug to be used stored in association with the treatment date is displayed on the measurement date (that is, the treatment date). A corresponding mark and a measurement date corresponding to the mark are displayed. In this example, for each measurement date 2003/8/8, 2003/9/8, 2003/10/3, 2003/11/1 of the subject ID 987654321 in the measurement history DB shown in FIG. Since the date corresponding to each measurement date is stored as the treatment date of the examiner ID, each mark □, ■, ☆, ★ and the measurement date corresponding to each mark 2003/8/8, 2003/9 / Corresponding to 8, 2003/10/3, 2003/11/1, a rehabilitation menu (for example, PEP therapy) and / or a medicine to be used (for example, spiriva) stored in association with each treatment day is displayed. In addition, when the treatment date corresponding to the measurement date is not stored, it is determined whether or not the treatment date corresponding to the date between the measurement date and the next measurement date is stored. The rehabilitation menu and / or the medicine to be used stored in association with the treatment date are displayed. Here, since the rehabilitation menu and / or the medicine to be used corresponding to the date of the day are not yet stored in the treatment information DB in the state where the input on the treatment information input screen has not been performed yet, the date of the day The rehabilitation menu and / or the drug used corresponding to is not displayed.

  Thus, in the graph in which a predetermined mark is shown in each of the coordinates corresponding to the predicted values of FEV1.0 / FVC and FEV1.0 / FEV1.0 stored in association with the measurement date, it further corresponds to each measurement date. The menu of rehabilitation to be performed and / or the type of drug is displayed, so that the doctor can change the predicted value of FEV1.0 / FVC, FEV1.0 / FEV1.0 depending on the implementation of the rehabilitation and the use of the drug. The treatment method for the subject can be examined by grasping whether or not the treatment has been performed.

  Here, when the graph is displayed, a predetermined operation, for example, an operation of the treatment information input button included in the operation key 4 is performed, so that the display 7 shows D11 in FIG. 9 instead of the graph. In addition, a treatment information input screen is displayed in which the date of the current day is input as the treatment date and the same ID as the subject ID input on the input screen is input as the subject ID. Here, as shown in D12, the rehabilitation menu to be performed on the subject is selected from the pull-down menu, and similarly, in the state where the drug to be used for the subject is selected from the pull-down menu, By operating the input completion button, the selected rehabilitation menu and / or medicine to be used are stored in the treatment history DB in association with the inputted subject ID and treatment date.

  As a result, the rehabilitation menu and / or the drug used corresponding to the date of the day is stored in the treatment information DB. Next, the graph is displayed again on the display 7 instead of the treatment information input screen. At this time, if the rehabilitation menu and / or the medicine to be used are stored in the treatment history DB in association with the treatment date corresponding to the measurement date, the rehabilitation menu and / or the medicine to be used corresponding to the date of the day is displayed.

[3. (Functions related to forced vital capacity measurement)
As described above, the respiratory function test apparatus 1 of the present invention measures the forced vital capacity, which is the amount of breath that can be inhaled and exhaled at once. This effort vital capacity is an amount that can be trusted only when the subject makes the best effort and exhales to the full. If the value of this effort vital capacity cannot be measured accurately, the above-mentioned first one-second rate is not a reliable value. Therefore, in order to make the value of the effort vital capacity accurate, the respiratory function testing apparatus 1 of the present invention has a function as described below.

  The flow rate of the subject is measured by the flow sensor 5, the differential pressure tube 16, the pressure sensor 10, the A / D converter 11, and the CPU 12, which are the measurement means described above. As shown in FIG. 12 (a), the sample is sampled and shown as a flow volume curve on a graph with the horizontal axis representing time and the vertical axis representing respiratory flow. Here, the respiratory flow rate is shown with positive exhalation and negative inspiration.

  This flow volume curve will be described with reference to FIG. First, in measuring the forced vital capacity, the subject exhales, and the exhalation at that time is indicated by a curve indicated by A. Next, the subject inhales greatly, and the inhalation at that time is shown in the curve shown in B. Further, after the inhalation of B, the subject exhales at a stretch, and the exhalation at that time is indicated by a curve indicated by C.

  Here, the CPU 12 is an example of a start time specifying means, and specifies the start time of expiration when measuring the value of the forced vital capacity, which is the respiratory capacity. In this example, the start point of expiration is specified by either one of the following two specifying methods or a combination of both methods.

  First, the first method is a method of specifying the start time of expiration by detecting the time when the positive and negative of the respiratory flow rate is changed. Specifically, a time point when the respiratory flow rate changes from negative to positive, that is, a time point when the inspiration of B changes to C exhalation is detected, and this time point is specified as the start time of expiration. By this method, it is possible to accurately specify the start point of expiration and obtain an accurate measured value of forced vital capacity.

  The second method is a method of specifying the start time of expiration by detecting the time when the positive / negative of the value obtained by differentiating the respiratory flow rate with respect to time changes. Specifically, the time point at which the time differential value of respiratory flow (ie, respiratory acceleration) changes from positive to negative is detected, and this time point is specified as the start point of expiration. Here, the time differential value of the respiratory flow changes from positive to negative within a relatively short time from the start of exhalation, so the time required to measure the forced vital capacity (for example, 6 seconds) Therefore, it is possible to specify the time when the time differential value of the respiratory flow changes from positive to negative as the start time of expiration. By this method, it is possible to accurately specify the start point of expiration and obtain an accurate measured value of forced vital capacity. In addition, when there are a plurality of time points at which the time differential value of the respiratory flow changes from positive to negative, the later time point may be specified as the start time of expiration. By doing so, it is possible to accurately specify the start point of expiration in the curve of C, excluding the time point when the first time differential value in the curve of A changes from positive to negative.

  Here, the exhalation start time specified by the first method may not be the time itself when the respiratory flow rate changes from negative to positive, and the time before and after this time may be determined as the exhalation start time. That is, it is only necessary to specify the start point of expiration by detecting the time point when the positive and negative respiration flows are changed.

  Similarly, the exhalation start time specified by the second method may not be the time when the time differential value of the respiratory flow changes from positive to negative, and the time before and after this time may be determined as the exhalation start time. . That is, it is only necessary to specify the start point of expiration by detecting the time point when the time differential value of the respiratory flow rate changes from positive to negative.

  Furthermore, both the first method and the second method are applied to detect the time point when the positive and negative respiratory flow rates change and the time point when the positive and negative respiratory flow time differential values change, respectively. Or before and after that, you may make it identify as an expiration start time.

  Next, the CPU 12 is an example of a counting means, and counts the expiration duration based on the expiration start time specified by the start time specifying means, specifically, the first method, the first method, The elapsed time from the expiration start point specified by the method 2 or the third method is counted.

  The display 7 is an example of an informing means for informing the expiration duration time counted by the counting means, and displays the elapsed time from the specified expiration start time on the display. In this example, as shown in FIG. 12B, the elapsed time is displayed at the upper right of the graph, for example, “3 seconds have elapsed”. Therefore, it is possible to grasp whether the expiration duration has reached a predetermined time required for measuring the forced vital capacity, and an accurate measured value of the forced vital capacity can be obtained.

  The display 7 serving as a notification means notifies the remaining time until the expiration time counted by the counting means reaches a predetermined time (in this example, the time required for measuring the forced vital capacity). The difference between the elapsed time from the specified exhalation start time and a predetermined time (for example, 6 seconds) determined in advance is displayed. In this example, as shown in FIG. 12B, the remaining time up to a predetermined time is displayed at the upper right of the graph, for example, “3 seconds remaining” is displayed. This predetermined time is a time required to measure the forced vital capacity, that is, a time sufficient for the subject to make the best effort to exhale to the full extent, for example, 6 seconds. The forced vital capacity here is calculated as the time integral value of the respiratory flow from the expiration start point to the expiration end point. For example, by defining the expiration end point as 6 seconds after the expiration start point, The integrated value of the respiratory flow for 6 seconds is calculated as the forced vital capacity. Accordingly, the forced vital capacity may be indicated as, for example, a 6-second amount that is the amount of breath exhaled during the first 6 seconds after the start of expiration.

  Further, the display 7 serving as the notification means keeps the expiration until the expiration duration time counted by the counting means reaches a predetermined time (in this example, the time required for measuring the forced vital capacity). In this example, until the elapsed time from the start of expiration reaches the predetermined time (for example, 6 seconds), as shown in FIG. Message “Please take a breath”. The subject who sees this message tries to exhale as much as possible. Therefore, an accurate measured value of forced vital capacity can be obtained. When the respiratory function testing device has a voice output function such as a speaker, a voice “please take a breath” may be output to encourage the subject to exhale. . That is, the notification means may be a speaker.

  As described above, the respiratory function test apparatus 1 according to the present example measures the respiratory flow rate by measuring the respiratory flow rate and time-integrating the respiratory flow rate. Therefore, it is possible to obtain time series data of the respiratory volume, specify the expiration start point based on the obtained respiratory volume, and perform the expiration time counting and notification as described above. . Hereinafter, a method for specifying the expiration start time based on the time series data of the respiratory capacity will be described. It should be noted that a respiratory function test apparatus of a type that measures respiratory volume and obtains a respiratory flow rate by time-differentiating the measured respiratory volume (for example, a cylinder-shaped internal piston moves in response to exhalation / inspiration, and the amount of movement The following method can also be applied to a type in which respiratory volume is measured by detecting the volume by a volume detector.

  In this case, the measured respiratory volume, so-called volume, is sampled as time-series data, and is shown as a volume curve on a graph with the horizontal axis representing time and the vertical axis representing respiratory volume, as shown in FIG. . Here, the respiratory capacity is shown with the expiratory volume as positive and the inspiratory volume as negative.

  This volume curve will be described with reference to FIG. First, in measuring the forced vital capacity, the subject exhales, and the exhalation volume at that time is indicated by a curve indicated by A. Next, the subject inhales a large amount of air, and the amount of inspiration at that time is shown in the curve shown in B. Furthermore, after inhaling in B, the subject exhales at a stretch, and the exhalation volume at that time is indicated by a curve shown in C. The forced vital capacity here is calculated as an increase in the respiratory capacity from the start of expiration to the end of expiration. For example, by defining the end of expiration as 6 seconds after the start of expiration, The increase in respiratory capacity for 6 seconds is calculated as the forced vital capacity. Accordingly, the forced vital capacity may be indicated as, for example, a 6-second amount that is the amount of breath exhaled during the first 6 seconds after the start of expiration. The one second amount is calculated as an increase value of the respiratory capacity for one second from the expiration start time.

  Here, the CPU 12 of the respiratory function test apparatus 1 is an example of a start time specifying means, and specifies the start time of expiration when measuring the value of the forced vital capacity, which is the respiratory capacity. In this example, the start point of expiration is specified by either one of the following two specifying methods or a combination of both methods.

  First, the first method is a method of identifying the start time of expiration by detecting the time when the positive / negative value of the value obtained by differentiating the respiratory capacity with time is changed. Specifically, the time point when the value obtained by differentiating the respiratory capacity with respect to time (ie, the respiratory flow rate) changes from negative to positive, that is, the time point when the inspiration of B changes to the expiration of C is detected. As specified. By this method, it is possible to accurately specify the start point of expiration and obtain an accurate measured value of forced vital capacity.

  The second method is a method of identifying the start point of expiration by detecting the time when the value obtained by differentiating the respiratory capacity with respect to time and the sign of the value obtained by differentiating with time are changed. Specifically, the time point when the second derivative value of the respiratory capacity (that is, the acceleration of breathing), which is a value obtained by further differentiating the time derivative value of the respiratory volume with time, is changed from positive to negative. Identified as the start of expiration. Here, the second derivative value of the respiratory capacity changes from positive to negative within a relatively short time after the start of exhalation, and therefore, the time required to measure the forced vital capacity (for example, 6 seconds) On the other hand, there is no problem even if the time point at which the second derivative of the respiratory volume changes from positive to negative is specified as the start point of expiration. By this method, it is possible to accurately specify the start point of expiration and obtain an accurate measured value of forced vital capacity. In addition, when there are a plurality of time points at which the second derivative value of the respiratory capacity changes from positive to negative, it is preferable to specify the later time point as the start time of expiration. By doing so, it is possible to accurately specify the start point of expiration in the curve of C, excluding the time point when the first secondary differential value in the curve of A changes from positive to negative.

  Here, the expiration start time specified by the first method does not have to be the time when the time differential value of the respiratory capacity changes from negative to positive, and the time before and after this time may be determined as the expiration start time. That is, it is only necessary to identify the start point of expiration by detecting the time point at which the positive / negative of the time differential value of the respiratory capacity changes.

  Similarly, the expiration start time specified by the second method does not have to be the time when the secondary differential value of the respiratory capacity changes from positive to negative, and the time before and after this time may be determined as the expiration start time. good. In other words, it is only necessary to specify the start point of expiration by detecting the time when the sign of the second derivative value of the respiratory capacity changes.

  Further, by applying both the first method and the second method, the time point when the positive / negative sign of the time differential value of the respiratory capacity changes and the time point when the positive / negative sign of the second derivative value of the respiratory capacity change, respectively, You may make it specify the intermediate | middle time of both time points, or its front and back as an expiration start time.

[4. Information providing system)
Finally, FIG. 14 shows an information providing system 100 including a PC 110 that is a client machine connected to the respiratory function testing device 1 described above and a server 120 that is a server machine connected to the PC 110 via a communication line.

The A hospital, B hospital, and C hospital PC 110 are connected to the Internet via a modem, while the university hospital PC 110 is connected to a server in the university hospital via a hub.

  The server 120 is connected to the PC 110 in the university hospital via a hub, acquires data stored in the hard disk of the PC 110, and stores it in the hard disk of the server 120.

However, when the subject ID matches the subject ID included in the data request, information corresponding to the subject ID is not returned. The PC 110 that has received the information returned from the server 120 displays the received information on a display and presents it to a doctor or a laboratory technician.

  Here, regarding the determination of whether or not the data stored in the server 120 matches the data included in the data request, it may not be a complete match. For example, if the age included in the data request is 55 years, the age may be matched in the range of 50 to 59. Similarly, the predicted values of FEV1.0 / FVC and FEV1.0 / FEV1.0 are not completely matched but may be matched within a range of ± 0.1 with respect to the values. Further, the information of the subject included in the data request is not limited to age and sex, but may be other information such as weight and smoking history.
