Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a portable low-frequency treatment device that performs treatment by flowing a low-frequency stimulation pulse current through the human body, and in particular, A control mechanism controls the frequency and intensity of the stimulation pulse current.

(Prior art) Conventionally, a treatment device body worn on the human body has a battery as a small power source, an electronic circuit that generates a low-frequency stimulation pulse current, and a positive and negative electrode that is connected to this electronic circuit and comes into contact with the skin. A portable small-sized low-frequency treatment device is known that is integrally provided with a pair of output electrodes.

Conventional low-frequency treatment devices of this type have a structure in which the speed, ie, frequency, and intensity of the stimulation pulse current cannot be adjusted. However, if the frequency and intensity cannot be adjusted in this way, appropriate stimulation cannot be obtained, which is inconvenient.

Therefore, in the above-mentioned low-frequency treatment device, the frequency and intensity of the stimulation pulse current are set to Sl! Il equipped with a switch such as a tact switch for one section on the main body of the treatment device.
An L structure has also been adopted, but in the past, the switch for the frequency wA node and the switch for adjusting the strength were separate.
In addition, two or more switches were provided, with each having an increase switch and a decrease switch. However, if there are two or more adjustment switches like this, it will be complicated to operate, and there is also the risk of erroneous operation. I couldn't operate the switch from above.

(Problems to be Solved by the Invention) As mentioned above, in the conventional small portable low-frequency treatment device in which the frequency and intensity of the stimulation pulse current can be adjusted, there are two adjustment switches on the treatment device body. Because of the above-mentioned arrangement, there was a problem that the operation of the switch was complicated and that the switch could not be operated from above clothes.

The present invention aims to solve these problems, and is capable of adjusting the frequency and strength of the stimulation pulse current with a single switch, has a simple configuration, and has good switch operability. The object of the present invention is to provide a low-frequency treatment device whose switch can be operated even over clothes. Furthermore, in this low frequency treatment device,
The purpose is to make it possible to clearly know the adjustment status of frequency and intensity according to the operation of the switch.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, the low-frequency treatment device according to claim 1 of the present invention includes a power source such as a battery, an electronic circuit that generates a low-frequency stimulation pulse current, and an electronic circuit that generates a low-frequency stimulation pulse current. It comprises a treatment device main body provided with an output electrode connected to a circuit, and one operation switch provided on the treatment device main body to adjust the frequency and intensity of the stimulation pulse current, and the output electrode A human body detecting means for detecting whether or not the human body detecting means is attached to the human body, and when the output electrode is not attached to the human body 81, the frequency of the operation of the operation switch is adjusted according to the output signal from the human body detecting means. The device is equipped with a microphone [switching means consisting of a 1:1 viewer, etc.] that adjusts the strength of the operation of the operation switch when the output electrode is attached to the human body.

Furthermore, in the low frequency treatment device according to claim 2, when the output electrode is not attached to the human body, the display device such as a light emitting diode provided on the treatment device body and the output signal from the human body detection means are used. A display control means is added to display the display at a frequency corresponding to the frequency of the stimulation pulse current, for example, to blink the display, and to stop the display, for example, to turn off the display when the output electrode is attached to the human body.

(Function) In the low frequency treatment device according to claim 1 of the present invention, when the output electrode provided on the treatment device main body is not attached to the human body,
The human body detecting means detects that the human body detecting means is not worn, and the switching means adjusts the frequency of the operation of the operation switch based on the output signal from the human body detecting means. Therefore, if the operation switch on the treatment device main body is operated at this time, the frequency of the stimulation pulse current output from the output electrode will be adjusted. On the other hand, when the output electrode is attached to the human body along with the treatment device main body, the human body detection means detects that the output electrode is attached to the human body, and the switching means adjusts the strength of the operation of the operation switch based on the output signal from the human body detection means. shall be. Therefore, if the operation switch is operated at this time, the intensity of the stimulation pulse current will be adjusted. Then, a low-frequency stimulation pulse current generated by an electronic circuit using a battery as a power source flows into the human body at an appropriate frequency and intensity through an output electrode, thereby performing treatment.

Furthermore, in the low frequency treatment device of claim 2, when the output electrode is not attached to the human body, the display control means uses an output signal from the human body detection means to set the display control means at a frequency corresponding to the frequency of the stimulation pulse current output. A display device such as a light emitting diode on the main body of the treatment device is displayed, for example, by blinking. Therefore, the user can know the speed of the stimulation pulse current to be output based on the display on the display even if the treatment device itself is not attached to the human body, and can adjust the frequency by operating the operation switch. This allows for appropriate adjustment.

On the other hand, once the output electrode is attached to the human body, the display control means stops the display, for example turns off the light, in response to an output signal from the human body detection means, thereby preventing wasteful power consumption. In this case, since the stimulation pulse current flows through the human body, the user can know the strength of the stimulation pulse current by feeling the stimulation, and can appropriately adjust this strength by operating the operation switch.

It has the function of a display control means that turns off the light when it is attached to the device.

Note that the correspondence with the block diagram in FIG. 2 is indicated by the chain line in FIG.

Next, the operation of the above embodiment will be explained.

First, how to use it will be explained. After operating the power switch 14 to turn it on and before attaching the treatment device main body 11 to the human body, the tactile switch 13 is suppressed to adjust the speed, that is, the frequency, of the stimulation pulse current. At this time, since the light emitting diode 71 blinks at the same frequency as this frequency, the adjustment is made with reference to this blinking. Next, the output electrode 12a.

12b is brought into contact with the skin, and the treatment device main body 11 is attached to a desired position such as an acupuncture point on the human body. Here, the intensity of the stimulation pulse current is adjusted by operating the tactile switch 13. Here, adjustments are made depending on the actual sensation of stimulation. and,
A pulse current is passed through the output electrodes 12a and 12b to provide stimulation to the human body, thereby treating stiff shoulders, muscle pain, and the like. After 1M of treatment, the treatment device main body 11 is removed from the human body and the power switch 14 is turned off.

Next, details of the operation will be explained with reference to the 7[1-chart in FIG. 3 as well.

When the power switch 14 is turned on, a reset signal is input to the port 0 of the microcomputer 21, and the microcombi 1-21 is reset. As a process on the software of the microphone [:I:1 viewer 21], after the reset 1-, initial setting is performed and A=O is set (step 2). Here, A is the tact switch 13
Indicates the presence or absence of input from switch A.
-1, and if there is none, it becomes A-0. Thereafter, the switch input timing state (step O) is entered, but when the tact switch 13 is pressed and input is made to the boat ■, a low voltage is applied to the output electrode 12a (step ◎).

This voltage is relatively low so that it is not felt by the human body even if the output electrodes 12a, 12b are attached to the human body. The process to output this weak output is as follows:
It is similar to that during treatment described below.

Then, while the weak output is being output, the microcomputer 21 determines the state of the input boat (2), and based on this state, determines whether the output electrodes 12a, 12b are attached to the human body (step O). . Output electrode 1
If 2a and 12b are not attached to the human body, the picture electrodes 12a and 12b are in a non-conductive state, so the transistor 72 is off and the input port ■ is in the 1"I G state.
H (P3=O). If Pa = 0, the frequency setting can be changed (step ◎). In this way, each time the tactile switch 13 is pressed while the device is not attached to the human body, the frequency setting is changed to, for example, 3 tlz->711z->
It changes cyclically in the order of 1011z->3 Hz.

At this time, there is an output from the output port (3) at the same frequency as the set frequency, and the light emitting diode 77 blinks.

On the other hand, if the output electrodes 12a, 12b are attached to the human body, the picture electrodes 12a, 12b become conductive through the human body, the voltage at the base of the transistor 72 increases, and this transistor 72 turns on, so that the input The state of boat ■ becomes LOW (P3'\0).

If it is P340, the boat ■ is always) (IQH), the light emitting diode 71 is turned off, and the setting of the strength of the stimulation pulse current, that is, the output voltage value to the human body is changed (step). Setting this output voltage value is
This is done by the combination of 1.0W1H11-IG of the output port 00o, and 23=8 voltage values can be set.

The timer is then turned on (step ■).

This timer interrupts after turning on the reciprocal of the set frequency, that is, the period, for example, 100 to 3 Q Q 1 sec. Then, at the same time as the timer turns on, the microphone [1] oscillating means 2 in the computer 21
2, a rectangular wave oscillation signal of about 10 kHz is output from the output port (Step O).

This oscillation signal turns the transistor 41 on and off, but immediately after the transistor 41 is turned off by the coil 42, a high voltage is generated on the collector side of the transistor 41 due to a back electromotive force. In this way, the low battery voltage Vo is boosted and a high voltage is generated as a boost pulse, but the generated high voltage is gradually accumulated in the capacitor 45.

Then, a comparison is made between the charging voltage value of the condenser 45 and the set voltage value set by the combination of 3-horn output cap@0@) (7) HI GHSLOW (
Step ■). In other words, the combination of output ports oO@) determines the on/off combination of transistors 6G and 61゜62, and resistors 56 and 57, 58, 59.
The voltage division ratio between these resistors 56 and 57.5 is determined.
While the voltage at the connection point a with 8.59 is lower than the zener voltage of the zener diode 66, the transistor 67 is off, and the input ports -1 to -2 are 1-II GH, so the microcomputer 21 maintains the set voltage value. It is judged as follows. In this case, it is determined whether or not the tact switch 13 has been operated (step O), and if there is a switch input, A=1
After that (step O), the process returns to step 0, and the capacitor 45 is further charged.

On the other hand, when charging of the capacitor 45 progresses and the voltage at point a becomes higher than the Zener voltage, the Zener diode 66 becomes conductive, the transistor 67 is turned on, and the input port
Since the voltage becomes LOW, the microcomputer 21 determines that the voltage is higher than the set voltage value. In this case, the oscillation signal is no longer output from the boat ■, and the capacitor 45 is no longer output.
Accumulation of charge does not proceed, and the switch input timing becomes *<step. Here, if there is a switch input, A,
= 1 (step 0).

In this way, a high voltage is stored in the condenser 45 in response to the boat O@e(7) HIGH, LOW combination.

Then, after the timer is turned on and one cycle of the stimulation pulse current has elapsed, a timer interrupt occurs.
The output boat ■, which was LOW until then, becomes HIGH (
step 0). Then, the transistor 49 is turned on, the transistor 47 is turned on, and the electric charge accumulated in the capacitor 45 is transferred to the output electrode 12a,
The energy is released into the human body as a resistor connected to 12b. At this time, the human body feels it as a stimulus. Note that the time for the output port (2) to become HIGH, that is, the pulse width of the stimulation pulse, is about 0.1++ seconds. At this time, the strength of the stimulation changes depending on the charging voltage of the capacitor 45. Note that even if the charging voltage of the capacitor 45 does not reach the predetermined voltage value determined by 0 (lit) (7) HI GH, LOW combination t) IcJ:, the period of the stimulation pulse current When a timer interrupt occurs, the output port becomes HIGHl.

Also, when a stimulating pulse current is output to the human body,
Depending on the state of the input boat ■, the output electrodes 12a, 12
It is determined whether or not b is applied to the human body (step ◎). Then, if it is attached to the human body, it is determined whether there has been a switch input within the time of one cycle so far (step ◎), and if A=O, the process returns to step ■; if A'lFO, then As A=O (step ◎
), return to step ■ and change the output voltage value setting. −・If it is not attached to the human body, that is,
If the treatment device main body 11 has been removed from the human body, the microcomputer 21 enters the 5TOP mode (step O).

Although not shown in the flowchart, a timer different from the above-mentioned timer is used, for example, at 30 minutes after the power is turned on.
Even though the treatment device main body 11 is attached to the human body, the system automatically enters the 5Tor' mode. If you press the tact switch 13 in this state, the input boat ■ will go high.
By becoming H, the signal returns from the 5TOP mode.

According to the above configuration, both the frequency and the intensity of the stimulating pulse current can be adjusted to m with one tact switch 13, so the configuration is simple, and the tact switch 13 has good operability. This switch 13 can be operated even over clothes.

Furthermore, since the tact switch 13 is provided on the surface of the treatment device main body 11 opposite to the output electrodes 12a and 12b that come into contact with the skin, it is easier to operate.

Furthermore, the frequency is adjusted by the output electrode 12a.

12b must be attached to the human body, but in this case, the light emitting diode 77 blinks at the same frequency as the set frequency, so the user can use the blinking to actually apply the light to the human body. Even if no current is applied, the frequency of the stimulation pulse current can be known and this frequency can be adjusted appropriately. On the other hand, the stimulation pulse current strength of 111 m is carried out with the output electrodes 12a and 12b attached to the human body, but at this time, since the human body is actually energized, the user feels a sense of stimulation. The strength can be known and this strength can be adjusted appropriately.

Then, after the output electrodes 12a, 12b are attached to the human body, unnecessary light emitting diodes 71 are turned off, so current consumption can be reduced and wasteful power consumption can be prevented.

Note that after the treatment time is over, for example, after the treatment device main body 11 is removed from the human body, or after 30 minutes have passed after the power is turned on,
The light emitting diode 71 may be made to blink for a certain period of time to notify the user that the treatment has ended.

Further, in the above embodiment, the display device is the light emitting diode 71, but the display device may be a piezoelectric buzzer or the like.

Next, another embodiment of the present invention will be described based on FIG. 6.

In this embodiment, a touch switch 81 is used as an operation switch for adjusting the frequency and intensity of the stimulation pulse current. One of the pair of contacts of this touch switch 81 is connected to the positive electrode of the battery 31 via a resistor 82, and the other is connected to the base of an NPN transistor 83. The collector of this transistor 83 is a resistor 84.
It is connected to the positive electrode of the battery 31 via the emitter, and its emitter is connected to the negative electrode of the battery 31. Also,
The collector is connected to the input port ■■ of the microcomputer 21, and is also connected to the negative electrode of the battery 31 via a capacitor 85.

Then, if the touch switch 81 is open, the boat ■■ is I-11G 11, but the touch switch 81 is open.
If you touch both contacts with your fingers and make these contacts conductive, the transistor 83 will turn on and the switch input will be turned on.
■ becomes t-OW.

According to the above configuration, even if something accidentally hits the switch 81, the switch 81 will not be turned on, so the setting of the frequency or intensity of the stimulation pulse current will not be changed inadvertently. can be prevented.
