- the condition for starting evaluation control may be that a specified operation has been performed on an operation unit (not shown) provided on the monitoring device 10, or that another condition has been met (for example, the power has been turned on, a predetermined reservation time has arrived, etc.).
- the control unit 30 executes the control of FIG. 7 and performs the first evaluation control in step S11.
- the first evaluation control is a control that performs the above-mentioned distance measurement control shown in FIG. 4, and then analyzes the waveform obtained by the distance measurement control to calculate an evaluation value.
- the control unit 30 first performs the above-mentioned distance measurement control and obtains waveform data that indicates the correspondence between the elapsed time since the start of the distance measurement control and the "value indicating the distance from the monitoring device 10 to the bladder bottom 112".
- This waveform data can be expressed as a value indicating the distance to the bladder bottom for each time, as shown in FIG. 8.
- the horizontal axis indicates the elapsed time
- the vertical axis indicates the value indicating the distance to the bladder bottom.
- the control unit 30 When performing distance measurement control in the first evaluation control, the control unit 30 preferably cooperates with the notification unit 34 to give the user an instruction for measuring the maximum lift.
- This instruction for measuring the maximum lift is an instruction to convey the action to be performed by the user in step S11, and is an instruction to convey the action to be performed by the user when performing distance measurement to calculate the maximum lift.
- the control unit 30 performs a first voice instruction during the period from starting distance measurement control in response to the start of the first evaluation control until the end of the distance measurement control.
- the first voice instruction is, for example, an instruction to perform repeated voice output after performing voice output instructing normal breathing.
- the voice output instructing normal breathing is, for example, a voice output by the notification unit 34 issuing a message saying "Please breathe normally".
- the repeated voice output is, for example, a voice output in which the notification unit 34 outputs a voice saying "Inhale” and then waits for a certain time (for example, 5 seconds), and the notification unit 34 outputs a voice saying "Exhale” and then waits for a certain time (for example, 5 seconds), alternately repeated a predetermined number of times (for example, 3 times).
- the control unit 30 After issuing such a first voice instruction, the control unit 30 issues a second voice instruction.
- the second voice instruction is, for example, a voice instruction to contract the pelvic floor muscles by outputting a voice of "Contract while exhaling" by the notification unit 34, and then a voice instruction to wait for a certain period of time (e.g., 5 seconds).
- the control unit 30 issues a third voice instruction after such a second voice instruction.
- the third voice instruction is, for example, a voice instruction to relax the pelvic floor muscles by outputting a voice of "Take a breath and relax" by the notification unit 34, and then a voice instruction to wait for a certain period of time (e.g., 5 seconds).
- the control unit 30 alternately repeats the second and third voice instructions a predetermined number of times (e.g., 5 times) to give the user instructions for measuring the maximum lift amount.
- a waveform such as that shown in FIG. 8 or FIG. 9 is obtained during the period when the instruction to measure the maximum lift amount is given.
- the "convex waveforms" indicated as lifts 1 to 5 are convex waveforms obtained upon each second voice instruction, and the "waveforms with reduced values” following each convex waveform are reduced waveforms obtained upon each third voice instruction.
- control unit 30 when the control unit 30 performs evaluation value calculation processing after distance measurement control, it finds the maximum value Y1 in the "convex waveform" during the period of the second voice instruction, finds the minimum value Y2 in the "waveforms with reduced values” obtained upon the third voice instruction immediately after this second voice instruction, and finds the value ⁇ Y1 of Y1-Y2, which is the difference between the maximum value Y1 and the minimum value Y2. Note that when finding the maximum value Y1 of the "convex waveform", the maximum value during the period from the start of the second voice instruction until the first predetermined time has elapsed or until the start of the next third voice instruction may be set to Y1.
- the minimum value during the period from the start of the third voice instruction until the second predetermined time has elapsed or until the start of the next second voice instruction may be set as Y2.
- the ⁇ Y1 obtained in this way is set as the lift amount in the contraction operation that caused the maximum value Y1 and the minimum value Y2 for calculating the ⁇ Y1.
- the control unit 30 obtains such a value ⁇ Y1 (lift amount) for each contraction operation (each second voice instruction), and sets the maximum value of the multiple values ⁇ Y1 (lift amount) obtained by each contraction operation (each second voice instruction) as the maximum lift amount Ym.
- the lift amount ⁇ Y1 corresponds to an example of a parameter and corresponds to an example of "the movement distance between the position of the bladder base in the relaxed state and the position of the bladder base in the contracted state in the operation in which the pelvic floor muscle switches between the relaxed state and the contracted state".
- the maximum lift amount Ym corresponds to an example of an evaluation value and corresponds to an example of "the maximum value of the multiple movement distances measured in the above operation that is determined in advance". Note that FIG. 8 shows an example in which contraction and relaxation movements are performed normally, and FIG. 9 shows an example in which relaxation is insufficient due to hypertonia.
- the maximum lift amount can be calculated as described above, but it is also possible to obtain, for example, the lift amount in each contraction movement, and the maximum and minimum values in each contraction movement. Furthermore, the control unit 30 can also calculate the average value Ya of each ⁇ Y1 (each lift amount) obtained for each contraction movement.
