DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a low-frequency therapeutic device effective for stiffness, paralysis and pain.

“Prior Art” By applying a low-frequency current to a human body using a low-frequency treatment device, treatments for relieving stiffness, paralysis and pain are performed. As a conventional low frequency treatment device of this kind, an operating means for changing the output intensity of the low frequency, a setting means for setting the treatment time to an arbitrary time, and various low-frequency devices prepared to obtain a stimulus with a change. It is known to have a selecting means for arbitrarily selecting a frequency waveform.

By using the low-frequency treatment device having such a configuration for the human body and arbitrarily setting the above-mentioned operation means, symptoms such as stiffness, paralysis and pain can be recovered.

[Problems to be solved by the invention] By the way, in the above-mentioned low frequency treatment device, as a procedure for starting the treatment, the treatment time is set, the low frequency output waveform is selected, and the low frequency output intensity is set. There is a problem that the operation cannot be easily performed because the operation must be performed in three steps.

The present invention has been made under such a background, and an object thereof is to provide a low-frequency treatment device capable of starting treatment with less operation.

"Means for Solving the Problem" The present invention is directed to a low frequency generating means for generating a plurality of low frequency currents having different waveforms, a timer for controlling the output time of the low frequency generating means, and an arbitrary treatment time for the timer. A first operating means for setting the above, a second operating means for selecting the output waveform of the low frequency generating means, a storage means for storing predetermined time data, and a case where the timer is not set for the time. The automatic setting means for reading the time data from the storage means and setting it in the timer when the second operation means is operated.

[Operation] According to the above configuration, when the time waveform is not set in the timer when the output waveform of the low frequency generating means is selected by the second operating means, the time data is supplied from the storing means to the timer, Time is set.

Therefore, when the treatment is started, even if the treatment time is not set, the treatment time can be automatically set by performing the operation of selecting the output waveform.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a low frequency treatment device L according to an embodiment of the present invention.
FIG. 3 is a diagram showing a configuration of an internal circuit of FIG.

In this figure, reference numeral 2 denotes a treatment time setting switch for arbitrarily setting the treatment time. By sequentially pressing the treatment time setting switch 2, the time set in the timer T can be changed and the treatment time can be set to an arbitrary time. Reference numeral 3 is a treatment time display for displaying the treatment time, and displays the time each time the timer T counts the time. 5a
Reference numerals 8a to 8a denote oscillators that output first to fourth low frequency waveforms having different low frequencies and different pulse widths. Reference numeral 4 is a low-frequency output waveform selection switch for selecting any of the first to fourth low-frequency waveforms. By sequentially pressing the low frequency output waveform selection switch 4, one of the oscillators 5a to 8a is selected via the control unit A, and a desired low frequency waveform can be selected. For example, when the switch 4 is first pushed, the oscillator 5a
Is selected to output the first low-frequency waveform, and when the switch 4 is pressed next, the oscillator 6a is selected and the second low-frequency waveform is output. Similarly, every time the switch 4 is pressed, the third, fourth, first, second, ... Low frequency waveforms are sequentially output. C is a comparator, which compares the signal Ts output from the timer T with the reference value "0" and outputs the signal Cs as the comparison result. Further, R is a read control unit, and
The read signal Rs is output by Cs and the signal 4s output from the switch 4. Reference numeral 10 is a ROM in which predetermined time data is stored. When the read signal Rs is input, the time data D is output to the timer T and the time set in the timer T is set. Reference numerals 5,6,7,8 are low frequency output waveform selection indicators for displaying the low frequency waveform selected by the low frequency output waveform selection switch 4 by a lamp. This low-frequency output waveform selection display 5 lights the lamp when the first low-frequency waveform is selected, and indicates that the first low-frequency waveform has been selected. Similarly, indicators 6, 7, 8
Lights up when the 2nd, 3rd, and 4th low-frequency waveforms are selected. 9
Is a low frequency output intensity controller that changes the low frequency output intensity output from each of the oscillators 5a to 8a via the control unit A.

Further, FIG. 2 is a plan view showing an external configuration of the low frequency treatment device L shown in FIG. 1, and in this figure, 1 is a power switch.

When the treatment is started by using the low frequency treatment device L having such a configuration for the human body, first, the power switch 1 is turned on. Next, the low frequency output waveform selection switch 4 is pressed to select the first to fourth low frequency waveforms suitable for the treatment. Here, for example, when the third low frequency waveform is selected, the low frequency output waveform selection display 7 is turned on. When the switch 4 is first pressed to select the low-frequency waveform, if the timer T has not been set, its output signal Ts becomes "0", and this signal "0" is output from the comparator C. It is compared with the reference value "0", and the output signal Cs of the comparator C becomes "1".
Then, the output signal Cs "1" and the signal 4s "1" from the switch 4 are input to the read control unit R, and the read control unit R outputs the read signal "1" to the ROM 10. As a result, the time data D stored in the ROM 10 is output to the timer T, and the time (treatment time) set in the timer T is automatically set. Next, the low frequency output intensity adjuster 9 is turned to adjust the output low frequency to an intensity suitable for the symptom. The treatment can be started by the above operation. In addition to the automatic setting described above, the treatment time can be set arbitrarily by the treatment operator or the operator operating the treatment time setting switch 2 during treatment.

[Advantages of the Invention] As described above, according to the present invention, the low frequency generating means for generating a plurality of low frequency currents having different waveforms, the timer for controlling the output time of the low frequency generating means, and the timer First operating means for setting an arbitrary treatment time, second operating means for selecting an output waveform of the low frequency generating means, storage means for storing predetermined time data, and time setting for the timer. When the second operation means is operated in the case where the treatment is not performed, since the automatic setting means for reading the time data from the storage means and setting the timer is provided, the operation for setting the treatment time is performed at the start of the treatment. Even if it is not necessary, the treatment time can be set automatically by performing the operation of selecting the output waveform, which has the effect that the treatment can be started with fewer operations. is there.
