And an electromagnetic brake 68 operatively connected via a chain 66. The electromagnetic brake 68 controls the rotational resistance by, for example, adjusting the magnitude of the eddy current generated in the rotating disk, or controls the rotational resistance by adjusting the magnitude of the generated current induced in the rotating coil. Control. The electromagnetic brake 68 functions as an exercise load adjusting unit that changes an operation state of the exercise mechanism, thereby changing a load imposed on the living body during exercise.

FIG. 3 shows an electronic control unit 28 for controlling the load of the ergometer 6 and displaying and controlling the recovery curve after exercise.
FIG. 3 is a functional block diagram illustrating a main part of the control function of FIG.
In the figure, the cuff pressure control means 70 is a reference blood pressure measurement means which is activated prior to continuous blood pressure measurement, that is, prior to use of the ergometer 6, for example, for determination of the pressure pulse wave blood pressure correspondence shown in FIG. During the 72 measurement periods, the compression pressure of the cuff 10 is varied according to well-known measurement procedures. For example, after the cuff pressure control means 70 rapidly increases the compression pressure of the cuff 10 to a preset target pressure increase value of about 180 mmHg higher than the systolic blood pressure of the living body, the cuff pressure control means 70 measures 3 mmHg in the measurement section where the blood pressure determination algorithm is executed. When the blood pressure measurement is completed, the pressure of the cuff 10 is released.

The reference blood pressure measuring means 72 generates a cuff pulse wave generated as pressure oscillation of the cuff 10 in the process of gradually lowering the compression pressure of the cuff 10 in the above-described measurement section prior to the exercise load control by the exercise load adjusting means 90. BP _SYS , mean blood pressure BP _MEAN ,
The diastolic blood pressure BP _DIA is measured and displayed on the display 36.

When the blood pressure value is measured by the reference blood pressure measuring means 72 prior to the exercise load control by the exercise load adjusting means 90, the pressure pulse wave blood pressure correspondence determining means 74 is detected by the pressure pulse wave sensor 38. pressure pulse wave magnitude P _M (t) and the lower peak value P _Mmin and the upper peak value P _Mmax of the reference blood pressure measured by the measuring means 72 blood pressure values BP (systolic blood pressure value BP _SYS, diastolic blood pressure BP _DIA Is determined in advance for a predetermined living body. This correspondence is, for example, as shown in FIG.
α · P _M (t) + β. Here, α is a constant indicating a slope, β is a constant indicating an intercept, and EBP is an estimated blood pressure value determined continuously.

The estimated blood pressure value determining means 76 determines the correspondence EB determined by the pressure pulse wave blood pressure correspondence determining means 74.
From P = f (P _M ), based on the magnitude P _M (t) of the pressure pulse wave sequentially detected by the pressure pulse wave sensor 38, the estimated blood pressure value EBP (systolic blood pressure value EBP _{SY S} , diastolic blood pressure value EB)
P _DIA ) are sequentially determined, and the determined estimated blood pressure value EBP is determined.
Is continuously displayed on the display unit 36 as a trend. The cuff pressure control means 70, the reference blood pressure measurement means 72, the pressure pulse wave sensor 38, the pressure pulse wave blood pressure correspondence relation determination means 74, and the estimated blood pressure value determination means 76 synchronize the blood pressure value of the living body with the pulse in a non-invasive manner. As a continuous blood pressure measuring means (biological information detecting means) 78 for continuously measuring the blood pressure.

The pulse rate determination means 80 calculates the pulse rate PR (1 / min) of the living body based on, for example, the cycle of the pressure pulse wave output from the pressure pulse wave sensor 38, thereby synchronizing with the pulse cycle. To continuously determine the pulse rate PR. The exercise intensity calculating means 82 calculates the exercise intensity PRP (= PR × EBP) which is the product of the pulse rate PR calculated by the pulse rate determining means 80 and the systolic blood pressure value EBP _SYS estimated by the estimated blood pressure value determining means 76. _SYS : Pressure Rate Produ
ct) is sequentially calculated in synchronization with the pulse cycle. This exercise intensity PRP indicates the actual exercise intensity of the living body,
It may also be referred to as exercise load, exertion intensity, or exertion load.

The target value determining means 84 is based on a set input signal or a turning point generated in a process of increasing the exercise intensity PRP when an increasing load is applied in a predetermined pattern prior to the movement of the living body. , The target value PRP _M of the exercise intensity PRP is determined. For example, a rising exercise intensity P
When the target value PRP _M is determined based on the break point of the RP, when the load of the ergometer 6 is sequentially increased with the passage of time, the break point of the exercise intensity PRP that increases with the load is detected, and the break point is detected. Based on the exercise intensity PRP at the time of occurrence or a correction value taking into account the response delay of the living body, exercise ability, gender, etc., a value lower than the exercise intensity PRP at the time of occurrence of the breakpoint by a predetermined value is determined as the target value PRP _M.

[0025] Exercise adjusting means 90 adjusts the load of said ergometer 6 so that the actual exercise intensity PRP target exercise intensity value PRP _M determined by the target value determining means 84 so That matches to follow When the elapsed time from the start of the exercise reaches the preset exercise time,
The movement of the living body is terminated by setting the load on the ergometer 6 to zero. The exercise end determining means 92 determines that the load on the ergometer 6 is zero by the exercise load adjusting means 90 when the elapsed time from the start of exercise of the living body reaches, for example, a target exercise time set in advance based on the exercise prescription. It is determined whether or not it has been performed.

When the end of exercise of the living body is judged by the end-of-exercise judging means 92, the recovery curve determining means 94 sets the continuous blood pressure measuring means 7 after the end of the exercise of the organism.
8 sequentially stores the systolic blood pressure value EBP _SYS sequentially measured and the measurement time, and based on the stored values,
A recovery curve that changes toward the resting value of the systolic blood pressure value EBP _SYS , that is, the systolic blood pressure value EBP after the end of exercise
A recovery curve showing the time change of _SYS is determined. Preferably,
In order to facilitate comparison of the recovery curves on the screen of the display 36, which will be described later, the recovery curve deciding means 94 sets each of the peaks constituting the recovery curve based on the systolic blood pressure value EBP _SYS at the end of the exercise of the living body. A normalized recovery curve is determined by representing the hypertensive value EBP _SYS in a normalized manner.

The recovery curve storage means 96 stores a predetermined number of recovery curves determined by the recovery curve determination means 94 each time the movement of the living body ends. As the recovery curve storage means 96, the non-volatile storage device 63 of a type in which storage of information is not impaired even when the device power is turned off is suitably used. Further, the recovery curve stored in the recovery curve storage means 96 may be a recovery curve for each time or a recovery curve composed of an average value within a predetermined period of about one week or one month. Good.

The display control means 98 can compare the recovery curve newly determined by the recovery curve determination means 94 with the recovery curves stored so far in the recovery curve storage means 96 along a common time axis. Is displayed on the screen of the display 36. For example, as illustrated in FIG. 5, the display control unit 98 may display a first time indicating the lapse of time after the end of the movement of the living body.
A time axis X, a second time axis Y indicating when the recovery curve is determined by the recovery curve determining means 94, and a normalized systolic blood pressure value E
In three-dimensional coordinates consisting of a biological information axis Z indicating the size of BP _SYS , recovery curves RC _n , RC _n−1 , R
C _n−2 , RC _n−3 , and RC _n−4 are displayed in parallel along the first time axis X, and are sequentially displayed along the second time axis Y so as to form a new recovery curve. In FIG. 5, RC _n is a newly determined recovery curve, and RC _n−1 , RC _n−2 , RC _n
n-3 and RC _n-4 are recovery curves determined at the end of the previous biological exercise.

FIG. 6 is a flowchart for explaining a main part of the control operation of the electronic control unit 28. In step S1 in the figure (hereinafter, the steps are omitted), it is determined whether or not the exercise load device has been activated by operating an operation button (not shown). If the determination in S1 is denied, the process is made to wait. If the determination is affirmed, the target value PRP _M is read in S2 corresponding to the target value determination means 84. Next, in S3, the actual exercise intensity P
Ergometer 6 so that RP matches target value PRP _M
Is controlled. That is, the pulse rate PR and the systolic blood pressure value EBP _{SYS of} the living body are read, and the actual exercise intensity PRP (= PR × EBP _SYS ), which is the product thereof, is calculated, and the actual exercise intensity PRP and the target value PRP _M are calculated. Thus, the load of the ergometer 6 is adjusted so that the difference between the two is eliminated.

Then, in S4 corresponding to the exercise completion determining means 92, it is determined whether or not the elapsed time from the start of the exercise of the living body, that is, whether the exercise time of the organism has reached the preset target exercise time. You. Initially, this S4
Is denied, the above-mentioned S3 and subsequent steps are repeatedly executed. However, when the exercise time of the living body reaches the target exercise time,
Since the determination in S4 is affirmative, the load on the ergometer 6 is reduced to zero in S5. In this embodiment, this S
5 and S3 correspond to the exercise load adjusting means 90.

Next, at S6, the systolic blood pressure value EBP
_SYS is read with the current time, and S
In 7, after "1" is added to the contents T _EL of the timer counter for counting an elapsed time T _EL after exercise completion,
In S8, whether the elapsed time T _EL has reached the preset recovery curve display period setting T _O is determined. The recovery curve display period set value T _O is set to a period sufficient for determining the motor function or the cardiopulmonary function of the living body, for example, a time of about 3 minutes.

Initially, since the determination in S8 is negative, the steps from S5 are repeatedly executed, and the systolic blood pressure value EBP _SYS which decreases toward the value at rest after the end of the exercise is sequentially read together with the time at that time. And stored in a predetermined storage area in the RAM 34. However, when the elapsed time _TEL after the end of the exercise reaches the recovery curve display period set value T _O and the judgment in S8 is affirmed, the reading is performed by then in S9 corresponding to the recovery curve determination means 94. from systolic EBP _{SY S} and the time at that time after the end of the exercise was, current recovery curve is determined.
This recovery curve is not an absolute value representing the systolic blood pressure value EBP _SYS , but the systolic blood pressure value EBP read immediately after the end of exercise.
It is normalized by being expressed in a ratio based on _SYS . For example, the systolic blood pressure value EBP _SYS read immediately after the end of exercise is set as the reference value “1”, and the size of the subsequent systolic blood pressure value EBP _SYS is displayed as a ratio to the reference value “1”.

Subsequently, in S10, the data is obtained when the movement of the living body has been performed and stored in a predetermined storage medium such as an internal storage means such as a hard disk storage device or an external storage means such as a memory card. The past recovery curve is read from the storage medium. And
Step S11 corresponds to the display control unit 98, the screen of the display 36, for example, as shown in FIG. 5, the newly determined recovery curve RC _n is recovery curves up to and stored in the storage medium RC _n-1 , RC _n-2 , RC
