Description

  The present invention relates to a mobile terminal.

  Tests for confirming the effect of respiratory rehabilitation include an in-hour walking test and a shuttle walking test.

In-time walking test, for example, the subject walks back and forth as much as possible at a distance of 30 m for a certain time, and the walking distance, Borg scale (subject called maximum dyspnea or subjective exercise intensity) ), SpO ₂ (arterial oxygen saturation), and pulse. In the walking test in time, it is allowed to stop due to shortness of breath on the way or rest against the wall.

In the shuttle walking test, the subject walks back and forth between cones placed at both ends of a 10 m course, for example. The subject walks according to the dial tone output from the speaker. The interval between the beep sounds is shortened every minute so that the walking speed increases, for example, by 10 m / min. At this time, the walking distance, Borg scale, SpO ₂ and pulse are measured. The shuttle walking test is stopped when the subject is unable to keep pace or when clinical symptoms such as dyspnea appear. Note that the cone interval, the walking speed change amount, and the change interval are not limited to this, and are appropriately changed.

A pulse oximeter is used for the effect confirmation test of such respiratory rehabilitation. The pulse oximeter is attached to a predetermined living body part of a subject, outputs light toward the living body part, and measures a change in the amount of light transmitted or reflected through the living body part as a pulse signal, so that SpO _{2 is used.} Ask for. The pulse oximeter is generally capable of measuring a pulse in addition to SpO ₂ (see, for example, Patent Document 1).

JP 2007-289462 A

By the way, among the test items of the above gait test for confirming the effect of respiratory rehabilitation, SpO ₂ and pulse are measured by a pulse oximeter, but the Borg scale and gait distance (or the number of gait) are examined by a nurse or the like. It is necessary for an operator to measure it visually and to record it on a memo paper by handwriting.

The walking test report is created by taking the measurement data stored in the pulse oximeter into a personal computer after the walking test is completed, and executing the predetermined application software by the personal computer to create the SpO ₂ and pulse trend graph. Done in The walking test report is created by manually inputting the Borg scale, walking distance, etc., recorded by hand by the inspector, into the same report as the trend graph such as SpO ₂ and pulse. It is done by being incorporated.

  Thus, in conducting a walking test to confirm the effect of respiratory rehabilitation, the inspector needs to work to measure the Borg scale and walking distance (or the number of walking) and to input it to a personal computer. There was a drawback that it took a lot of time and effort.

  In addition, the gait test report is substantially created when the personal computer executes predetermined application software, but the conventional gait test report is still insufficient to confirm the effect of respiratory rehabilitation. For example, in the time walk test, the subject often became suffocating and unable to walk during walking, but this was not recorded in the report in the past or was difficult to see easily from the report. .

  The present invention has been made in consideration of the above points, and provides a portable terminal capable of displaying the confirmation of the effect of walking exercise in an easy-to-understand manner.

One aspect of the portable terminal of the present invention is:
An acquisition unit for acquiring measurement values of biological information and walking amount;
A display unit having a display screen capable of simultaneously displaying the acquired biological information and the measurement value of the walking amount;
On the display screen, an input unit that receives an input of a pedestrian's subjective exercise intensity and displays the input subjective exercise intensity on the display screen together with the acquired biological information and a measured value of the walking amount; ,
Equipped with,
The display unit displays the history of the measurement value of the biological information and the walking amount within the examination period on the same graph on the display screen,
The input unit displays the history of the subjective exercise intensity within the examination period on the same graph .

  According to the present invention, it is possible to display the confirmation of the effect of walking exercise in an easy-to-understand manner.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

<Overall configuration>
FIG. 1 is a schematic diagram showing the overall configuration of a walking test system according to an embodiment of the present invention. The walking test system 1 includes a pulse oximeter 100 and a tablet terminal 200. The pulse oximeter 100 and the tablet terminal 200 have a function capable of wireless communication with each other. In the case of the present embodiment, the pulse oximeter 100 and the tablet terminal 200 are capable of short-range communication based on the Bluetooth (registered trademark) standard. The pulse oximeter 100 transmits measurement data to the tablet terminal 200 wirelessly. The tablet terminal 200 collects the measurement data received from the pulse oximeter 100, displays the measurement result, and creates a walking test report.

  The pulse oximeter 100 includes a main body part 110 and a probe part 120. The main body part 110 and the probe part 120 are connected via a cable 130. The main body 110 can be mounted near the wrist of the subject using a belt (not shown), and the probe unit 120 can be mounted on the finger of the subject.

  FIG. 2 is a block diagram showing a main configuration of the pulse oximeter 100. The probe unit 120 of the pulse oximeter 100 is provided with a light emitting unit 121 and a light receiving unit 122. The light-emitting unit 121 includes a first light-emitting diode that emits red light (for example, wavelength 660 [nm]) that is highly sensitive to changes in arterial oxygen saturation, and infrared light that is less affected by arterial oxygen saturation (for example, And a second light emitting diode that emits light at a wavelength of 940 [nm]). The light receiving unit 122 includes a photodiode, and detects the light of the light emitting unit 121 that has passed through the finger. Note that the light receiving unit 122 may be arranged not in the light transmission path from the finger but in the light reflection path from the finger, and the light reception unit 122 may detect the reflected light from the finger.

The main body 110 obtains the subject's SpO ₂ and pulse based on the detection light obtained by the probe unit 120. This will be specifically described. The light emitting circuit 111 causes the first light emitting diode and the second light emitting diode of the light emitting unit 121 to emit light alternately at a predetermined interval. The transmitted light or reflected light from the finger at that time is detected by the light receiving unit 122, subjected to photoelectric conversion, and input to the light receiving circuit 112. The light receiving circuit 112 converts the current signal input from the light receiving unit 122 of the probe unit 120 into a voltage signal. In addition, the light receiving circuit 112 demodulates the two observation signals by separating the converted voltage signal into the components corresponding to the wavelengths of the red light and the infrared light described above. In addition, the light receiving circuit 112 performs processing such as amplification and analog-digital conversion on the demodulated observation signal, and outputs the processed observation signal to the CPU 113.

The CPU 113 calculates SpO ₂ and the pulse from the observation signal by executing a predetermined program. Since this calculation method is a known technique as described in Patent Document 1, for example, description thereof is omitted here. The CPU 113 controls each part of the pulse oximeter 100. Specifically, the CPU 113 performs various settings based on operation signals input from the operation unit 117. The CPU 113 performs operation control of the light emitting circuit 111, display control of the display unit 115, communication control of the communication unit 116, and the like.

  In addition to such a configuration, an acceleration sensor 118 is provided in the main body 110 of the pulse oximeter 100. The CPU 113 calculates the number of steps of the subject based on the output of the acceleration sensor 118.

The pulse oximeter 100 transmits the measured SpO ₂ , pulse, and number of steps to the tablet terminal 200 in real time by the communication unit 116.

  The tablet terminal 200 includes a display unit 210 formed of a liquid crystal display with a touch panel, and also has a wireless communication function for receiving measurement data transmitted from a pulse oximeter.

<Display of measurement results and creation of walking test report>
Next, display of measurement results and creation of a walking test report by the walking test system of the present embodiment will be described.

  In the case of the present embodiment, display of the measurement result of the walking test and creation of the walking test report are performed by the tablet terminal 200. That is, the tablet terminal 200 receives measurement data from the pulse oxystem meter 100, displays a measurement result on the display unit 210, and creates a report according to application software for performing a walking test.

  FIG. 3 shows a menu screen of the in-time walking test displayed on the display unit 210 of the tablet terminal 200. This menu screen is displayed when the application of the tablet terminal 200 is activated. In the case of the example in FIG. 3, the items “input”, “measurement”, “result”, and “setting” are displayed as menus, and the process of the item tapped by the user (inspector) is executed.

  When the user taps the “input” item, an input screen as shown in FIG. 4 is displayed. The subject information can be input using the input screen of FIG. As for the input of the subject information, the tablet terminal 200 communicates with the pulse oximeter 100 when the screen of FIG. 4 is displayed, and the subject information (subject ID, name) held in the storage unit 114 of the pulse oximeter 100 is displayed. , Date of birth, gender, height, weight) and setting information (walking time to test, recovery time, walking detection level (that is, sensitivity when calculating the number of steps from the output of the acceleration sensor)) Done. The tablet terminal 200 calculates the BMI from the height and weight. As described above, since the tablet terminal 200 acquires the subject information and the setting information from the pulse oximeter 100, the tablet terminal 200 is compared with a case where these information are input manually from the tablet terminal 200. The subject information and the setting information between the 200 and the pulse oximeter 100 can be reliably matched, and a mismatch due to an input error or the like can be avoided. However, the subject information and the setting information can be directly input from the tablet terminal 200. Further, the tablet terminal 200 obtains subject list information stored in the database of the external server by communicating with an external server (not shown), and is input by the user from the subject list information. The subject information can also be selected based on the subject ID. In addition, when the “registration” item is tapped on the input screen of FIG. 4, the tablet terminal 200 registers the currently displayed subject information and setting information. When the “return to menu” item is tapped, the menu screen of FIG. 3 is displayed. When the “OK” item is tapped, the screen shifts to the measurement preparation screen of FIG. However, when the preparation screen is set to OFF in the setting, the screen shifts to the resting screen of FIG.

When the preparation screen of FIG. 5 is displayed (measurement preparation stage), the tablet terminal 200 calculates and sets the subject's stride, walking speed, and the like. Moreover, the tablet terminal 200 displays the waveform (the step count waveform 11, the pulse waveform 12) for a user confirming the state of the apparatus currently used for the walk test. This will be specifically described. Based on the measurement data received from the pulse oximeter 100, the tablet terminal 200 displays SpO ₂ , pulse (PR), and the number of steps. When the item “test walking” is tapped, the tablet terminal 200 displays the number of steps (22 steps in the example in the figure) and the walking time (8 seconds in the example in the figure), and further, based on these, the stride ( 45 cm in the example in the figure) and walking speed (1.25 m / s in the example in the figure) are calculated and displayed, and the stride and walking speed are stored. Furthermore, the tablet terminal 200 displays the step count waveform 11 and the photoelectric pulse waveform 12 indicating the pulse. The step count waveform 11 is a waveform in which the position where the number of steps is counted is indicated by a mountain shape. A photoelectric pulse waveform 12 indicating a pulse is a photoelectric pulse waveform measured by the pulse oximeter 100. By displaying the step count waveform 11, the user can determine whether or not the setting of the walking detection level (sensitivity) is appropriate based on the step count waveform 11, and the communication between the pulse oximeter 100 and the tablet terminal 200. It will be possible to check if there is no break. That is, if the interval between the peaks appearing in the walking waveform 11 is extremely large or small, for example, or if a mountain does not appear in the first place, it is considered that the setting of the walking detection level is not appropriate. The user can see this and set the walking detection level appropriately. Further, by displaying the photoelectric pulse waveform 12 indicating the pulse, the user can determine whether or not the probe unit 120 of the pulse oximeter 100 is correctly attached to the subject based on the photoelectric pulse waveform 12. It becomes possible to confirm whether or not communication between the pulse oximeter 100 and the tablet terminal 200 is interrupted. In the preparation screen of FIG. 5, it is possible to input the “drug treatment before the test” and the presence / absence of “oxygen inhalation during the test”. In addition, you may enable it to input treatment time, the kind of medicine, etc. In addition, the “test time” can be changed. When the “return to menu” item is tapped, the menu screen of FIG. 3 is restored. When the “OK” item is tapped, the screen shifts to the resting screen of FIG.

When the resting screen of FIG. 6 is displayed (resting stage), the tablet terminal 200 collects and displays resting data before the walking test. Specifically, the tablet terminal 200 displays SpO ₂ , pulse, and step count values based on the measurement data received from the pulse oximeter 100. In practice, the number of steps is “0” because the subject does not walk at rest. In addition, the tablet terminal 200 displays SpO ₂ , the pulse rate, and the number of steps on the same graph in which the horizontal axis is time and the vertical axis is frequency. A mark (triangular mark in the figure) is displayed at a position corresponding to the current time in the graph. A pulse (PR) photoelectric pulse waveform 24 is also displayed. In addition, the user can input blood pressure on the resting screen. The blood pressure can be input a plurality of times, and the last input blood pressure is displayed. The blood pressure may be input by wirelessly receiving data from the sphygmomanometer in addition to manual input by the user. In addition, the “test time” can be changed on the resting screen. When the “Start” item is tapped, the screen shifts to the in-test screen of FIG. 7 and inspection is started. When the “preparation” item is tapped, the screen returns to the preparation screen of FIG. When the “return to menu” item is tapped, the menu screen of FIG. 3 is restored.

  Further, a Borg scale image 13 is displayed on the resting screen, and the user can input a Borg scale by tapping any Borg scale from the displayed Borg scale image 13. Incidentally, although the Borg scale is used in the present embodiment, it is of course possible to use a modified Borg scale. The tablet terminal 200 can switch according to the setting whether to use a Borg scale or a modified Borg scale. When the “Borg scale” item is tapped, the screen shifts to a Borg scale selection screen shown in FIG. That is, the Borg scale can be input from the screen of FIG. 6, but can also be input from the dedicated screen for inputting the Borg scale as shown in FIG. Since the description of the Borg scale is also displayed on the Borg scale selection screen in FIG. 9, even an inspector and a subject who are unfamiliar with the walking test can easily select the Borg scale.

When the in-test screen of FIG. 7 is displayed (the stage during walking), the tablet terminal 200 receives the measurement data during the walking test from the pulse oximeter 100 and displays it in real time. Specifically, the tablet terminal 200 displays the numerical values of SpO ₂ , pulse, and step count in real time based on the measurement data received from the pulse oximeter 100. In addition, the tablet terminal 200 displays SpO ₂ , the pulse rate, and the number of steps on the same graph with the horizontal axis representing time and the vertical axis representing frequency. Specifically, an SpO ₂ trend graph 21, a pulse trend graph 22, and a step count bar graph 23 are displayed on the same graph. A mark (triangular mark in the figure) is displayed at a position corresponding to the current time in the graph. A pulse (PR) photoelectric pulse waveform 24 is also displayed. In addition, the “test time” can be changed. In addition, when the “interrupt” or “rest” item is tapped, the walking test can be interrupted or rested. In addition, when the item “Cancel inspection” is tapped, the inspection is terminated. The inspection may be interrupted, rested, or terminated after displaying a confirmation message for interrupting, resting, or canceling and / or outputting sound. Further, the Borg scale image 13 is displayed on the screen during the test, and as described above, the Borg scale can be input using the Borg scale image 13 or the dedicated screen shown in FIG. The tablet terminal 200 automatically displays the Borg scale input screen (FIG. 9) at a predetermined walking test time (for example, every 1 minute) after displaying the image under test of FIG. You may prompt at regular time intervals. In addition, a message prompting the user to input a Borg scale may be displayed at regular intervals.

  When the recovery screen of FIG. 8 is displayed (recovery stage), the tablet terminal 200 receives and displays measurement data during recovery of the subject from the pulse oximeter 100. The recovery stage is a state where the subject has finished walking. On the recovery screen, an image similar to the screen under test is displayed. Borg scale input is also possible. When the “end” item is tapped or a predetermined recovery time has elapsed, the tablet terminal 200 automatically switches the screen to the measurement result screen of FIG. 11 or FIG.

  Incidentally, when the input screen of FIG. 4, the resting screen of FIG. 6, the in-test screen of FIG. 7, and the recovery screen of FIG. 8 are displayed, the shutter button (not shown) of the camera of the tablet terminal 200 is pressed. When operated, the tablet terminal 200 displays the image input screen shown in FIG. 10 so that the subject image can be captured. The photographed image of the subject is recorded in association with the subject ID.

  As shown in FIGS. 11 and 12, the measurement result screen covers two screens (two pages). Switching between the screen of FIG. 11 and the screen of FIG. 12 can be performed by flicking or dragging by the user.

FIG. 11 is a diagram showing a measurement history display screen among the measurement result screens. The history of measurement results before the start of walking (at rest), during walking, and after the end of walking (during recovery) is displayed in a graph. The representative value is displayed as a numerical value. Actually, the SpO ₂ trend graph 21, the pulse trend graph 22, the bar graph 23 indicating the number of steps, and the Borg scale history (circled numbers in the figure) are displayed on the same bluff. . The bar graph 23 of the number of steps in the case of FIG. 11 shows the accumulated number of steps divided every 30 seconds. That is, when the number of steps in the current 30-second period is 0, the bar graph for the current 30-second period is displayed at the same height as the bar graph for the previous 30-second period. In the present embodiment, in addition to the bar graph 23 indicating the number of steps, a mark indicating whether it is a walking period or a non-walking period is displayed. In the case of the embodiment, a band-shaped mark along the time axis is displayed. In the example of FIG. 11, since no mark is displayed in the period of 2 minutes 30 seconds to 3 minutes, it can be seen that this period was a non-walking period. Thus, SpO ₂ and with trend graph of the pulse, by displaying the graph showing the history of the number of steps, can recognize at a glance the change of SpO ₂ and pulse rate, the relationship between the walking. Furthermore, since the Borg scale history is also displayed on the same graph, the relationship between the change in SpO ₂ and the pulse and the breathing difficulty of the subject can be recognized at a glance.

  In the measurement result screen of FIG. 11, the tablet terminal 200 has a predicted walking distance (242.1 m in the figure), an actual walking distance (blank in the figure and input by an inspector), and an ideal prediction. The walking distance (250 m in the figure) and the ratio are displayed. The predicted walking distance is obtained by multiplying the actual number of steps counted during the test (539 steps in the figure) by the step length (45 cm in the figure) obtained by the previous test walking. The actually measured walking distance is a walking distance actually measured by the inspector and input by the inspector. The ideal predicted walking distance (predicted value in the figure) is obtained by multiplying the walking speed obtained by the test walking and the test time. The ratio is a value obtained by dividing the ideal predicted walking distance (250 m in the figure) by the predicted walking distance (242.1 m in the figure). The value of the ratio is almost 100% if there is no period in which the subject stops walking during the test, and increases as the period in which the subject stops walking exceeds 100%. This ratio can be used as an index for confirming the effect of respiratory rehabilitation.

  Furthermore, on the measurement result screen of FIG. 11, an oxygen flow rate image 25 showing the history of the oxygen flow rate of the oxygen concentrator is displayed. This assumes that the subject performs a walking test using an oxygen concentrator. The oxygen flow rate image 25 is a display in which the oxygen flow rate for each time is color-coded over the time direction. When the item “return to menu” is tapped on the screen of FIG. 11, the screen shifts to the menu screen of FIG. 3.

FIG. 12 is a diagram showing a comparison screen among the measurement result screens, and is displayed so that the previous and current measurement results can be compared. Specifically, the number of steps, the minimum SpO ₂ , the maximum PR, the Borg scale, the maximum blood pressure, and the total walking distance of the previous time and the current time are displayed as numerical values. Further, the number of steps is displayed as a line graph on the graph 26 with the horizontal axis as time. In the example of FIG. 12, the upper line graph shows the current measurement result, and the lower line graph shows the previous measurement result. In this line graph, the occurrence positions of the minimum SpO ₂ and the maximum PR are indicated by arrows. The upper two arrows indicate the position where the minimum SpO ₂ is generated in the previous time and the current time, and the lower two arrows indicate the position where the maximum PR is generated in the previous time and the current time. In addition, the number of steps, the minimum SpO ₂ , the maximum PR, the Borg scale, the maximum blood pressure, and the total walking distance of the previous time and the current time are displayed on the radar chart 27. The outer line is the current radar chart, and the inner line is the previous radar chart. As described above, the previous measurement result and the current measurement result are displayed using the radar chart 27, so that the effect of the rehabilitation can be comprehensively confirmed. In the numerical value, line graph, arrow, and radar chart, the previous measurement result and the current measurement result are color-coded. Thereby, the user can grasp at a glance whether each numerical value, each line graph, each arrow, and each radar chart indicates the previous measurement result or the current measurement result. The previous data can be changed by tapping the display area of the previous measurement result. That is, when the display area of the previous measurement result is tapped, the tablet terminal 200 displays a list of measurement results of the same subject ID among the past measurement results recorded, and the user can Desired measurement results can be selected as past data to be compared. When the item “return to menu” is tapped on the screen of FIG. 12, the screen shifts to the menu screen of FIG. 3.

  When the user taps the “Result” item on the menu screen of FIG. 3, the tablet terminal 200 displays the list screen shown in FIG. 13. On the list screen, a list of results stored in the tablet terminal 200 is displayed. The user can select a report mode, an import mode, or a delete mode. FIG. 13 is a list screen in the report mode. In the report mode, when the user selects and taps any item number “1” to “12”, a report screen (FIGS. 14 and 15) is displayed. In the import mode, when the user selects and taps the item number, the tablet terminal 200 communicates with the oxygen concentrator corresponding to the subject indicated by the item, so that the oxygen from resting to the end of recovery can be obtained. The operation log of the concentrator can be acquired. This assumes that the subject performs a walking test using the oxygen concentrator, and the import result is reflected in the oxygen flow image 25 shown in FIG. In the delete mode, when the user selects and taps an item number, the measurement result data of the subject indicated by the item can be deleted.

  In the report mode, for example, when the item number “1” is selected and tapped, the report screens of FIGS. 14 and 15 are displayed. 14 and 15 cover two screens (two pages) as described with reference to FIGS. 11 and 12, and can be switched by flicking or dragging by the user. The display contents on the report screens of FIGS. 14 and 15 are the same as the display contents of the measurement result screens of FIGS. 11 and 12. However, in the report screens of FIGS. 14 and 15, an item “Preview” is displayed, and when the item “Preview” is tapped by the user, a print preview screen shown in FIGS. 16 and 17 is displayed. On the print preview screen, an item “print execution” is displayed. When this “print execution” item is tapped, the in-hour walking test report is printed by a printer connected to the tablet terminal 200 by wire or wirelessly. The

  Incidentally, as shown in FIG. 18, the tablet terminal 200 can also display a blood pressure list screen input from the rest screen (FIG. 6) and the recovery screen (FIG. 8). Further, as shown in FIG. 19, the tablet terminal 200 displays an image of the subject captured by the camera of the tablet terminal 200 while being at rest, during a walking test, during recovery, etc. in association with the subject ID. You can also do that.

As described above, according to the walking test system of the present embodiment, the pulse oximeter 100 measures the walking amount in addition to SpO ₂ and the pulse, and the tablet terminal 200 measures SpO ₂ , the pulse and the walking amount. By receiving information and displaying the history of SpO ₂ , pulse, and walking amount within the examination period on the same graph, it is possible to reduce the time and effort required for the in-hour walking test and to breathe in association with walking. Rehabilitation effect confirmation can be displayed more clearly.

In addition, as shown in FIGS. 7, 8, 11, 14, and 15, the Borg scale history is displayed on the same graph as SpO ₂ , pulse, and walking volume, so that breathing during the walking test is suppressed. It is possible to express the correlation between the rise of the Borg scale due to the height and the patient's stoppage due to shortness of breath.

Also, as shown in FIGS. 7, 8, 11, 14, and 15, the Borg scale history is the height corresponding to the value of the Borg scale on the same graph as SpO ₂ , pulse, and walking amount. By displaying the position together with a number indicating the value of the Borg scale, it becomes possible to recognize at a glance how many Borg scales were.

  Further, the tablet terminal 200 displays a Borg scale selection screen (FIG. 9) within the inspection period, and the Borg scale selected by the user is input and recorded within the inspection period using the Borg scale selection screen. The scale can be easily recorded in real time.

  As described above, according to the present embodiment, all the information on the walking test is collected in real time on the tablet terminal 200, and the report is automatically created immediately after the test is completed, so that convenience for the inspector is improved and labor is saved. Therefore, there is an advantage that the inspector can perform the test while looking at the condition of the patient.

  Further, since the measurement data that must be manually input is remarkably reduced, it is possible to suppress a decrease in the reliability of the test due to an input error or falsification of the data, and it is possible to improve the reliability of the test.

  In addition, although the case where the number of steps was used as the walking amount displayed on the graph was described, the walking amount to be displayed is not limited to the number of steps, and a walking speed or the like may be displayed as the walking amount. In addition, the walking amount is not necessarily limited to the actual walking amount, and for example, walking by treadmill or step-up / down can be used as the walking amount.

Further, SpO _2, the display form of the pulse and the amount of walking is 7, 8, 11, 14 is not limited to the display mode shown in FIG. 15, in short, SpO _2, a history of the pulse and the amount of walking And display them on the same graph.

Furthermore, in the above-described embodiment, the communication terminal that receives information on SpO ₂ , pulse, and walking amount from the pulse oximeter 100 and displays the history of SpO ₂ , pulse, and walking amount within the examination period on the same graph. As mentioned above, although the case where the tablet terminal 200 was used was described, it replaces with the tablet terminal 200 and this invention can also be implemented with other communication terminals, such as a mobile phone and a personal computer with a wireless communication function. Further, in the above embodiment, SpO _2, has dealt with the case of using a pulse oximeter 100 as a device for measuring the information of the pulse and the amount of walking, not limited to the pulse oximeter 100, short, SpO _2, What is necessary is just to use the biological information measuring device which can measure the information of a pulse and the amount of walking. Furthermore, only the original data for SpO ₂ , pulse and walking amount may be measured by the biological information measuring device, and the final values of SpO ₂ , pulse and walking amount may be obtained by calculation using the communication terminal.

Furthermore, in addition to the parameters of the embodiment, the subject's respiratory rate may be measured and the history thereof may be displayed on the same graph as the history of SpO ₂ , pulse and walking amount. In this way, the state of respiratory rehabilitation can be confirmed more clearly.

  The above-described embodiments are merely examples of implementation in carrying out the present invention, and the technical scope of the present invention should not be construed as being limited thereto. That is, the present invention can be implemented in various forms without departing from the gist or the main features thereof.

  The present invention can be used for a test for confirming the effect of respiratory rehabilitation.
