Description

[Detailed Description of the Invention] The present invention relates to a low frequency treatment device having a timer function.

In general, low frequency treatment devices often have a configuration with a timer function, and this timer function makes it possible to ensure an optimal treatment time and prevent overuse. However, when treatment is interrupted due to receiving a phone call or visiting a customer,
If the treatment is restarted later without accumulating the previous treatment time, there is a high risk of overtreatment and skin pain. Conventionally, there has been no low-frequency treatment device that can prevent such overtreatment.

In view of these problems, the present invention aims to provide a low-frequency treatment device that integrates the treatment time from the beginning of treatment, and after restarting treatment, can perform treatment for the time that is calculated by subtracting the integrated value from the set time. It is something. The following will be described in detail based on examples.

FIG. 1 is a block diagram of an embodiment of the present invention.
1 is an output means for outputting a biological stimulation pulse, and 2 is an output control means consisting of a microprocessing unit.The output control means 2 controls the output waveform state of the biological stimulation pulse of the output means 1 and the presence or absence of the pulse output. It is something to control. Further, 3 is an operating means, 4 is a power supply means, and 5 is a human body.

In the above, in order to control the presence or absence of pulse output, the output control means 2 (a) sends a command signal to the output means 1 to temporarily stop or cancel the output by operating the operation means 3; (b) A first timer function that integrates the treatment time during which pulse output is generated for the output means 1; (c) A first timer function that integrates the treatment pause time during which pulse output is stopped for the output means 1. (iv) a function to turn off the power supply means 4 when the integrated value of either the first or second timer function exceeds the set time; It is something that exists. and,
The first and second timer functions can be initially set, and it is preferable that the second timer function is initially set semi-fixed.

In the processing program of the output control means 2, for example, as shown in the flowchart of FIG. 2, the timer times of the first and second timer functions are initially set in the first step (1). be.
When the power supply means 4 is turned on under this initial setting, the first and second timer functions are reset (step (2)). Thereafter, the stage (3) is that it is possible to receive a temporary stop operation signal (hereinafter referred to as a pause signal) from the operating means 3, and the stage (4) is to judge whether or not there is a pause signal at a high-speed repetition cycle.
Then, in step (4), when it is determined that there is no pause signal in step (3), the output control means 2 drives the output means 1 to send the low-frequency biological stimulation pulse to the human body. 5, during normal treatment, the first timer function accumulates the treatment time (5), and the first timer function determines whether the set time has exceeded the set time (6). ). If it is determined in step (6) that the set time has not been exceeded, the function processing step (7) is performed.
Feedback is given to (3), and the above operation is repeated.

Further, when it is determined that the pause signal of the operating means 3 is received in step (4), that is, the output control means 2
When the drive is stopped and the output means 1 temporarily stops outputting pulses, the second timer function accumulates the pause time (8), and the second timer function determines whether the set time has been exceeded or not. This is the step (9) of determining. If it is determined in step (9) that the set time has not been exceeded, step (10) is reached in which it is possible to receive an output stop release signal (hereinafter referred to as a pause release signal) from the operating means 3, and the pause is resumed. This is a step (11) in which it is determined at a high-speed repetition cycle whether or not there is a release signal. Stage in stage (11)
When it is determined that there is no pause release signal in (10), the
The feedback is fed back to step (8), and a loop is formed from step (8) to step (11). Therefore, when it is determined that a pause signal is received in step (4), step (5)
The integration of the treatment time by the first timer function will be stopped. Further, when it is determined in step (11) that there is a pause release signal in step (10), feedback is made to step (3) through step (12) of clearing the integrated value in the second timer function. Therefore, the integration of the treatment time by the first timer function in step (5) is restarted.

Further, in step (6) and step (9), when it is determined that the integrated values of the first timer function and the second timer function exceed the set time, respectively, a step (13) of turning off the power source means 4; It is what it is.

As described above, when the power supply means 4 is on, the output control means 2 controls the presence or absence of pulse output from the output circuit 1 in accordance with the pause signal or pause release signal from the operation means 3. At this time, the first
The timer function starts accumulating the treatment time at the same time as the treatment starts, stops the accumulation in response to a pause signal from the operating means 3, and restores the accumulation in response to a pause signal from the operating means 3. In addition, the output control means 2
When the pulse output of the output circuit 1 is stopped by the pause signal from the operating means 3, the timer function starts accumulating the treatment pause time, and clears the accumulation by the pause signal from the operating means 3. These,
When the integrated value of either the first or second timer function exceeds the set time, the power supply means 4 is turned off and the output circuit 1 is controlled to end the pulse output.

Regarding the output control means 2, although the explanation has been omitted regarding the control of the output waveform state of the biological stimulation pulse of the output means 1, as is often done in ordinary low frequency treatment devices, the control of the biological stimulation pulse output It is also possible to perform control such as gradually increasing the amplitude or changing the pulse polarity as appropriate.

In the above description, a case has been exemplified in which a microcomputer is applied to the output control means, but the present invention can also be achieved with a circuit configuration as shown in the block diagram of FIG.

In FIG. 3, 10 is an oscillation means, 11 is an output means, 12 is an output control means, 13 is an operation means, 1
4 is a power supply means, 15 is a human body, and 16 is a pose motion indicator. Further, in the output control means 12,
12a is a drive pulse interface, 12
b is a flip-flop, 12c is a first timer oscillator, 12d is a first counter, 12e is a second
12f is a second counter.

In this case, the flip-flop 12b acts as a command source to temporarily stop or cancel the output to the output means 11, and the combination of the first timer oscillator 12c and the first counter 12d generates a pulse output to the output means 11. It acts as a first timer function that accumulates the treatment time, and also
The combination of the second timer oscillator 12e and the second counter 12f accumulates the treatment pause time during which the output means 11 stops outputting pulses.
Also, a circuit formed by connecting the output sides of the first counter 12d and the second counter 12f to the power supply means 14 acts as a timer function of the power supply means 1.
This functions as a function to turn off the switch 4.

When the power supply means 14 is turned on, the flip-flop 12b, the first counter 12d, and the second counter 12f are reset. flipflop 1
2b outputs a high level signal (hereinafter referred to as H signal) when reset, and this H signal causes
The oscillation means 10 and the first timer oscillator 12c start operating. Thereby, the basic pulse of the oscillation means 11 is transmitted to the drive pulse interface 1.
2a becomes a drive pulse, and according to this drive pulse, a biological stimulation pulse is output from the output circuit 11 to the human body 15.

Now, when the flip-flop 12b outputs a low-bell signal (hereinafter referred to as L signal) in response to the pause signal from the operating means 13, the oscillation means 10 and the first timer oscillator 12c stop operating, and the output means 11 stops outputting. Further, the L signal causes the second timer oscillator 12e to start operating. At this time, the first counter 12d finishes counting the time from when the power supply means 14 is turned on to when the first timer oscillator 12c stops operating, that is, the treatment time, and stops counting. The second counter 12f starts accumulating the treatment pause time from the time the second timer oscillator 12e starts operating.

Then, when the integrated value of either the first counter 12d or the second counter 12f does not exceed the corresponding set time, when the flip-flop 12b receives a pause release signal from the operating means 13, the flip-flop 12b goes high. output a signal,
This H signal causes the oscillation means 10 and the first timer oscillator 12c to start operating, and the output means 11
will resume output. Also, the H signal causes the second
The counter 12e clears the integrated value and recovers.

Furthermore, when the integrated value of either the first counter 12d or the second counter 12f exceeds the corresponding set time, the power supply means 14 is turned off.

For this reason, the embodiment of the present invention shown in FIG. 3 operates in accordance with the present invention explained in FIGS. 1 and 2.

As is clear from the above explanation, according to the present invention, the treatment time and treatment stop time can be set, and as long as the set time is not exceeded,
The output of biostimulation pulses can be temporarily stopped at will. When restarting treatment after the output is temporarily stopped, the treatment time from the start of the treatment to the point in time when the treatment is temporarily stopped is accumulated, so the remaining treatment time is calculated by subtracting the accumulated value from the treatment setting time. Therefore, overtreatment can be prevented. Of course, the output temporary stop operation can be performed multiple times as long as it is within the above-mentioned set time.

Then, when the set time is exceeded, the power is turned off, so this is extremely suitable from the viewpoint of low power consumption, especially in the case of a small low frequency treatment device that uses batteries.
