Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a low-frequency treatment device that performs treatment by applying high-voltage stimulation pulses at low frequency to the human body, and in particular, The present invention relates to a storage case in which a low-frequency treatment device main body with an integrated child is stored.

(Prior Art) In a conventional low-frequency treatment device, a low-frequency treatment device main body that includes a built-in power supply battery and a stimulation pulse generation circuit, and a pair of conductors each having a treatment electrode are separate bodies. Then, plugs as power receiving terminals are connected to the tips of the lead wires extending from these conductors, and an output jack as an external connection terminal to which these plugs are detachably connected is provided on the main body of the low frequency treatment device. It had become.

However, such low-frequency treatment devices, in which the main body of the low-frequency treatment device and the conductor are separate, are sometimes inconvenient to use. Ultra-compact low-frequency treatment devices that are integrated with the main body have come into use. This ultra-compact low-frequency treatment device has a pair of treatment electrodes installed in the low-frequency treatment device itself, which has a built-in power source battery such as a lithium battery and a stimulation pulse generation circuit.

However, such ultra-compact low-frequency treatment devices are compact in size, and as a result, the area of the pair of treatment electrodes is small, and the distance between these treatment electrodes is also narrow. When treating such things, the irritation is weak and the treatment cannot be performed effectively.

Therefore, an auxiliary conductor that is detachably attached to the treatment electrode of the main body of the low-frequency treatment device has been attached as an accessory. In this conventional auxiliary guide, a pair of openings are formed in a sheet body that has a larger area than the main body of the low-frequency treatment device, and a pair of large treatment electrodes are provided facing each of these openings. The treatment electrodes of the low frequency treatment device main body are attached to these treatment electrodes through the openings.

However, even when such an auxiliary conductor is used, the distance between the pair of treatment electrodes is narrow, and unlike low-frequency treatment devices with separate conductors,
It is not possible to appropriately attach a pair of treatment electrodes to a human body. Moreover, having to prepare a dedicated auxiliary conductor is disadvantageous in terms of manufacturing and is also inconvenient for the user.

In addition, ultra-compact low-frequency treatment devices use small and low-capacity lithium batteries as power sources, so conventionally,
The battery consumed quickly, and the battery had to be replaced frequently, which was a hassle.

(Problems to be Solved by the Invention) As mentioned above, in the conventional ultra-compact low-frequency treatment device, the distance between the pair of treatment electrodes is constant, so depending on the treatment area on the human body, sufficient treatment effect may not be achieved. There was a problem that I couldn't get it.

Furthermore, since the capacity of the power source battery is small, there is a problem in that the battery must be replaced frequently.

The present invention aims to solve the above-mentioned problems by providing an ultra-compact low-frequency treatment device that can perform treatment by separating multiple treatment electrodes as needed. The aim is to make this possible with a simple structure using existing parts.

The treatment electrodes 33r and 33b are each made of, for example, an adhesive pad or conductive rubber, but the treatment electrodes 14* of the low frequency treatment device main body 11 are

Next, the outline of the configuration of the electric circuit will be explained based on FIG. 1.

For example, if the hair is inside the low frequency treatment device main body 11,
A diode 43 and the stimulation pulse generation circuit 44 are connected between the positive and negative electrodes of the battery 41, which is a lithium battery of
A boosting coil 45 and an ape type transistor 46 are connected in series. Also, this transistor 46

A connection point between the diode 47 and the emitter of the transistor 48 is connected to the negative electrode of the battery 41 via a capacitor 50. Further, a resistor 5I is connected between the base of the transistor 48 and the negative electrode of the battery 41.
and an l1pIl type transistor 52 are connected in series.

Further, the other treatment electrode +4b is connected to the negative electrode of the battery 41 via a parallel circuit of a resistor 53 and a diode 5i, and an npn transistor 55.
connected to the base of. The emitter of this transistor 55 is connected to the negative electrode of the battery 41.

Furthermore, a power supply circuit 61 that can be opened and closed from the one treatment electrode 14i to the stimulation pulse generation circuit 44 is provided.

That is, a PIIP type transistor 62 is provided between the one treatment electrode 14s and the connection point of the diode 43 and coil 45.

The base of this transistor 62 is connected to the negative electrode of the battery 41 via an npn transistor 64.

Although not shown, the stimulation pulse generation circuit 44
has a microcomputer as a control means. And on the output boat of this microcomputer,
The base of the transistor 46 (point a), the base of the transistor 64 (point b), and the base of the transistor 52 (point C) are connected, respectively. Furthermore, the collector of the transistor 55 (point d) is connected to the input port of the microcomputer. In addition,

Furthermore, although not shown in the circuit diagram of FIG.
It is connected between. Although this power switch is not necessarily necessary, it is good to have it in order to prevent minute power consumption when not in use and to prevent inadvertent stimulation.

On the other hand, in the storage case 21, the battery 71 and the diode 7 are connected between the case electrodes 24j and 24b.
2 are connected in series. The battery 71 is, for example, four AA batteries connected in series, and has an electromotive force of, for example, 6V, which is larger than the electromotive force of the battery 41 of the low frequency treatment device main body 11. Further, each of the case electrodes 24s and 24b is connected to both poles of the output jack 25, respectively.

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

When performing a treatment in which the area of the treatment electrode is small and the distance between a pair of treatment electrodes is small, as shown in FIG. A pair of treatment electrodes 14 made of adhesive pads! , 14b are attached to the skin, and the low-frequency treatment device main body 11 is directly attached to a desired position on the human body, thereby performing treatment.

First, a high-frequency boosting oscillation signal is output to point a. As a result, the transistor 46 is repeatedly turned on and off, and a high voltage is generated on the collector side of the transistor 46 by the coil 45 when the transistor 46 is turned off. In this way, the voltage of the battery 41 is boosted, and the generated high voltage is charged to the capacitor 50 via the diode 47 for preventing backflow. This is repeated until the charging voltage of the capacitor 50 is sufficiently increased. Note that even if the transistor 62 is turned on at this time, no current flows through the power supply circuit 61 due to the directionality of the connection of the transistor 62.

Then, the signal to point C, which had been LOW until then, temporarily rises to HIGH, and transistors 52 and 48, which had been off until then, turn on.

As a result, the high voltage charged in the capacitor 50 is transferred to the transistor 48, the resistor 49, 53, and the treatment electrode 1.
4+, which is applied as a stimulation pulse to the human body via 14b. That is, a current flows between the pair of treatment electrodes 1b and 14b through the human body. Note that the signal to point C is H.
When it is IGH, the signal to point b is LOW, and the transistors 62 and 64 are turned off.

This is repeated, and stimulation pulses are repeatedly applied to the human body at low frequencies to treat muscle pain, stiff shoulders, etc. Note that the strength of the stimulation pulse and the like can be adjusted by operating the adjustment button 15.

After the treatment, the treatment electrode 141 and Hb are peeled off from the skin, and the low frequency treatment device main body 11 is removed from the human body. Then, as shown in FIG. 3, the low-frequency treatment device main body 11 is inserted and stored in the storage recess 22 of the storage case 21 so that its bottom surface faces the inner bottom surface of the storage recess 22. In this stored state, both treatment electrodes 14 of the low frequency treatment device main body 11
1 and 14b are both case electrodes 241 inside the storage case 21.
, 24b, respectively. By the way, when the low-frequency treatment device main body 11 is stored, the power switch operator 13 fits into the notch 23 of the storage case 21.
The direction of fitting of both treatment electrodes 14s, 1 is regulated.
4b and both case electrodes Us, 24b, the polarity of contact cannot be mistaken.

If the low frequency treatment device main body 11 is stored in the storage case 21 in this way, the treatment electrode 14I made of an adhesive pad
, 14b, and prevents these treatment electrodes 14r, 14b from inadvertently sticking to something.

In addition, when it is desired to perform treatment by increasing the area of the treatment electrodes or by increasing the distance between a pair of treatment electrodes, it is possible to use the output jack of the storage case 21 while the low frequency treatment device main body 11 is stored in the storage case 21. 25 separate conductor 31g
, connect the plug 35 of 31b, and connect the pair of separate conductors 3.
1g and 31b are attached to appropriate positions on the human body for treatment. These separate conductors 31M and 31b are
Treatment electrode 33g +' 33b consisting of the adhesive pad
It is attached to the human body by pasting it on the skin, or by using a band or bandage.

If the treatment electrodes 33z, 33b are adhesive pads, they can be easily attached to the human body. In addition, the low frequency treatment device main body 11
Even if the power switch is retracted,
3 and adjustment button 15 are exposed and can be operated.

At this time, the stimulation pulses generated by the stimulation pulse generation circuit 44 in the low-frequency treatment device main body 11 are transmitted to the treatment electrodes 141, Nb of the same low-frequency treatment device main body 11, the case electrodes 24z, 24b that are in contact with these, and the output. Jack! 5
, the treatment electrodes 33g, 33b of the separate conductors 3h, 31b via the plug 35 and lead wires 34M, 34b.
is applied to the human body.

At this time, during the period when the boost oscillation signal is output to point a and the capacitor 50 is charged, the signal to point b is HIGH.
, the transistors 62 and 64 are turned on, and the power supply circuit 61 is closed. Therefore, the low frequency treatment device main body 1
1 from the battery 71 in the storage case 21 outside the case electrode 24
t, 24b, treatment electrode + of the low frequency treatment device main body 11
Power is supplied to the stimulation pulse generation circuit 44 in the low frequency treatment device main body 11 via the power supply circuit 41 , 14 b and the power supply circuit 61 . Moreover, since the battery 71 in the storage case 21 has a higher voltage than the battery 41 in the low-frequency treatment device main body 11 and has a diode 43 for backflow prevention, the stimulation pulse generation circuit 44 can be connected only from the battery 71 in the storage case 21. Power is supplied, but power is not supplied from the battery 41 of the low frequency treatment device main body 11.

Furthermore, when the signal to point C becomes HIGH and the capacitor 50 is discharged, the signal to point b becomes LO.
When the voltage drops to W, transistors 62 and 64 are turned off, and the power supply circuit 61 is opened. Therefore, the stimulation pulse current does not flow through the power supply circuit 61, but through the separate conductor 311.3.
It flows from the treatment electrodes 33s and 33b of 1b to the human body.

Moreover, at that time, the diode 72 in the storage case 21 is
Preventing stimulation pulses from being applied to battery 71.

After treatment, the separate conductor is removed from the human body, but the plug 35 is removed from the output jack 25 of the storage case 21 so that it does not get in the way when not in use.
b can also be stored separately.

According to the above configuration, not only can simple low frequency treatment be performed using only the low frequency treatment device main body 11 in which the treatment electrodes 14r and 14b are integrally provided, but also the separate conductor 31 can be used as needed. *, 31b can also be used appropriately to increase the therapeutic effect. That is, the treatment electrode 33z,
33b has a large area and these treatment electrodes 331.33
Separate conductor 31 that can freely increase the distance b
! , 31b, it is possible to expand the treatment area in the human body, and it is possible to obtain effective stimulation even when treating areas where stimulation is difficult to obtain, such as the feet. In this way, it is possible to respond to various treatment targets.

By the way, conventionally, in ultra-compact low-frequency therapy devices, the treatment electrodes are generally made of adhesive pads, so a storage case in which the treatment device itself is stored or a storage plate that is removably attached to the treatment electrodes, etc. Some kind of storage body was a necessary accessory. However, according to the above configuration,
Treatment using only the low frequency treatment device main body 11 and the separate conductor 311.

In order to enable both treatment using Hb, we used the storage case 21, which is a necessary part of the ultra-compact low-frequency treatment device, so we only need to make some design changes to this storage case 21, and the overall The structure is simple and the price can be lowered. At the same time, the existing separate conductors 31* and '31b can be used as they are, which is advantageous in manufacturing and highly convenient for the user. Moreover, the conventional low frequency treatment device main body 11 can be used without any design changes.

Of course, when using the separate conductors 31s and 31b, there is no need for a separate low-frequency treatment device body from the conventional conductors.

Although the battery 41 of the low-frequency treatment device main body 11 has a small capacity, during treatment using the separate conductors 311 and 31b, the battery 71 of the storage case 21 is transferred to the low-frequency treatment device main body 11.
Since power is supplied to the stimulation pulse generation circuit 44 of the main body 11, this power supply backup saves the consumption of the battery 41 of the low frequency treatment device main body 11, extends the life of the battery 41, and reduces the trouble of replacing the battery 41. decrease.

Note that although the diode 43 is not necessarily required, the presence of the diode 43 makes it possible to separate the separate conductor 31.
During treatment using the Hatake 31b, power can be supplied only from the battery 71 of the storage case 21, so that the consumption of the battery 41 of the low frequency treatment device main body 11 can be more effectively saved.

Using separate conductors, it is also possible to perform treatment with multiple treatment electrodes separated as appropriate, such as on the feet.

The therapeutic effect can be improved even when treating areas where stimulation is difficult to obtain. Moreover, this is possible by using the conventional low-frequency treatment device main body and separate conductor as is, and since the stimulation pulse generation circuit is common to both treatment types, the structure can be simplified, which is advantageous in terms of manufacturing.
