The above-mentioned conventional apparatus discloses a structure for energizing multiple affected areas, but a special structure for flexing and extending a human body joint to effectively perform functional training is disclosed. Not disclosed. That is, the above-mentioned conventional device is not intended to perform bending and extension of a human body joint, and therefore, outputs of two channels are applied to the muscles that bend the joint and the muscles that extend, respectively. The two muscles are not energized alternately. Therefore, it is impossible to effectively perform functional training by flexing and extending the joint.

If both output regulators 19 are in the zero position, the embodiment is activated. Conversely, if either one of the output regulators 19 is not in the zero position, the embodiment is deactivated. When the output of the mechanism 41 and the output of the channel A1 is adjusted, the output controller 19 is turned to automatically bring the channel A1 into the output state and stop the output of the channel B2, the other stop function 21, the channel A1 and the channel A2.

Similarly to the case of the channel A1, the other stop function 21 puts the channel A2 into the output state and stops the output of the channel A1 when the output of the channel A2 is adjusted. The oscillation frequency of the clock generator section 24 is the fundamental frequency of the embodiment.

The setting unit 8 is a frequency setting device 27 for setting the frequency of the low frequency current applied to the affected area. Furthermore,
The energization time setter 28 for setting the energization time of the low frequency current, the quiescent time setter 29 for setting the quiescent time of the low frequency current, and the rise time of the low frequency pulse width, which are activated when the intermittent energization described later is performed.

Is output alternately.

FIG. 2 shows an appearance of the main body case 38 of the embodiment, 39 is a panel cover, and 40 is the setting section 8.
(See FIG. 1) and the switch section 9 (see FIG. 1) and the like. FIG. 3 is a flowchart of the embodiment.

In using the embodiment, the positive and negative electrodes 18a and 18b of the channel A1 are attached to the muscles that bend the joint, and the positive and negative electrodes 18c and 18d of the channel B2 are attached.
Is attached to the muscle that extends the joint. Both the output controllers 19 of channels A and B are set to zero, and the power switch 6 is turned on.

When the power switch 6 is turned on, the zero position start function 41 causes one or both of the output regulators 19 of channels A and B to not be set to zero. The output of the channel in which the device 19 has not returned to the zero position does not output from the channel until the output controller 19 is returned to zero.

In setting the output, first, the output adjuster 19 of the channel A 1 is rotated from the zero position to set the channel A 1
The energization is started, and the energization is started by rotating to an appropriate position where a suitable energizing current is obtained and stopped, and then the position is set. Next, the output controller 19 of the channel Otsu 2 is rotated from the zero position and set to an appropriate position where a suitable energization current can be obtained.

When the output controller 19 of the channel Otsu 2 is rotated upward, the other stop function 21 causes the channel Otsu 2 to move.
The output is continuously obtained from, and for the time of this output adjustment,
The output from Channel A1 is stopped. Channel Otsu 2
When the rotation of the output controller 19 is stopped, the above-mentioned set output automatically appears from the channel A 1.

That is, by the action of the other stop function 21, while the output adjuster 19 of one channel is being rotated, the output is continuously obtained from that channel, and only during that time, the output of the other channel is changed. Pulse generation circuit 1
No pulse is applied to 1 from the microcomputer unit 3, and no output is output from the other channel. When the rotation of the output controller 19 of one channel is stopped, the other channel is automatically restored, both channels are in the operating state, and the output is ready to be generated.

In the normal operating state after the output setting is completed, the alternate output function 22 causes the channel A 1 and the channel O 2 to be alternately activated, and two pairs of positive and negative electrodes 18a, 18b, 18c. A low frequency current is alternately applied to 18d. When channel 1 output, the joint bends,
When Channel Otsu 2 outputs, the joint extends. Alternately energize the robot to repeatedly flex and extend the human joint, and perform training to expand the range of motion of the joint.

Explaining the energization state, first, a low frequency current flows from the channel A 1 for a predetermined time and then pauses, then a low frequency current flows from the channel B 2 for a predetermined time and then pauses, then a low frequency from the channel A 1 A frequency current flows, and so on.

The output indicator flashes so that it lights up in synchronization with an arbitrarily set frequency when each of the channels A and B is outputting.
When 2 is inactive or not outputting, it goes out. Depending on the symptom of the affected area, the F
The ES mode or the TENS mode is selected, and the energization method selection switch 35 selects continuous energization. When the embodiment is used for the purpose of pain relief or massage other than the purpose of function training, the energization method selection switch 35 may select intermittent energization or sparse energization. In that case, alternate output function 2
It is also possible to deactivate channel 2 and activate channels A and B simultaneously to output.

The setting unit 8 presets the frequency of the low-frequency current. Since this setting member is rarely operated during the treatment, the operation panel 40 on which the setting member is arranged is covered with the panel cover 39 so that the setting member does not move unintentionally due to contact with a foreign object, and the set value does not change. I am trying. When the set energization time has elapsed, the operation of the microcomputer unit 3 is stopped and the low frequency output of the embodiment becomes zero.
Alternatively, when the output adjuster 6 is rotated down to the zero position, the operation of the microcomputer unit 3 is stopped and the low frequency output of the embodiment becomes zero. The power switch 6 is turned off to end the training or treatment.

[0026]

The present invention according to claim 1 has an alternate output function of alternately outputting a low frequency current from the two channels 1 and 2, so that the human body joint is bent and extended to expand the range of motion of the joint. It is convenient because the functional training of can be carried out efficiently.

According to the second aspect of the present invention, when the output of one channel is adjusted, it has the other stop function of stopping the output of the other channel. Therefore, the bending motion of the joint caused by the one output is extended by the other output. This is convenient because it can be prevented from being interfered with by the movement of, and the output of both channels can be easily adjusted.
