DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Field of Industrial Application) The present invention relates to a low-frequency therapeutic device for applying a high-voltage stimulating pulse to a human body at a low frequency for treatment, and more particularly to a low-frequency therapeutic device. The present invention relates to a storage case in which a low-frequency treatment device body in which a child is integrated is stored.

(Prior Art) In a conventional low-frequency treatment device, a low-frequency treatment device main body having a power supply battery and a stimulation pulse generation circuit built-in, and a pair of conductors each having a treatment electrode are separate bodies. Then, a plug as a power receiving terminal is connected to the tip of each lead wire extending from each of these conductors, and a structure provided in the output jack low frequency treatment device main body as an external connection terminal to which this plug is detachably connected Was becoming.

However, such a low-frequency treatment device in which the main body of the low-frequency treatment device and the conductor are separate may be inconvenient to use, so that the conductor and the low-frequency treatment device can be easily treated. An ultra-small low-frequency treatment device that is integrated with the main body has come to be used. This microminiature low-frequency treatment device is one in which a pair of treatment electrodes are provided on the low-frequency treatment device main body itself, which incorporates a power supply battery such as a lithium battery and a stimulation pulse generation circuit.

However, such an ultra-compact low-frequency treatment device has a compact size, and accordingly, the area of the pair of treatment electrodes is reduced and the distance between the treatment electrodes is also reduced. When treating such as, the irritation feeling is weak and effective treatment cannot be performed.

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

However, even if such an auxiliary conductor is used, the distance between the pair of treatment electrodes is small, and the pair of treatment electrodes can be appropriately separated and attached to the human body like a low-frequency treatment device having a separate conductor. is not. In addition, it is disadvantageous in manufacturing and inconvenient for the user to prepare a dedicated auxiliary conductor.

In addition, the ultra-small low-frequency therapy device uses a lithium battery or the like that is small and has a small capacity as a power source.
The battery was exhausted quickly, and this battery had to be replaced frequently, which was troublesome.

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

Moreover, since the capacity of the power supply battery is small, there is a problem that the battery must be frequently replaced.

The present invention is intended to solve the above-mentioned problems, and in a microminiature low-frequency treatment device, it is possible to perform treatment with a plurality of treatment electrodes separated from each other, if necessary. The purpose of the present invention is to make it possible with a simple structure using existing parts.

It is also intended to extend the life of a power source such as a battery and reduce the time and effort required for battery replacement.

That is, the low frequency treatment device main body and the conductor are used in a conventional low frequency treatment device which is a separate body. Each of the treatment electrodes 33a and 33b is made of, for example, an adhesive pad or conductive rubber, but has a larger area than the treatment electrodes 14a and 14b of the low frequency treatment device main body 11. Also, each of the conductor covers 32a,

Next, the outline of the configuration of the electric circuit will be described with reference to FIG.

In the main body 11 of the low frequency treatment device, between the positive electrode and the negative electrode of the battery 41 made of, for example, a 3V lithium battery,
The diode 43, the boosting coil 45 of the stimulation pulse generating circuit 44, and the npn-type transistor 46 are connected in series. Further, a diode 47, a pnp type transistor 48 and a resistor 49 are connected in series between the connection point of the collector of the transistor 46 and the coil 45 and one of the treatment electrodes 14a. The connection point between the diode 47 and the emitter of the transistor 48 is connected to the negative electrode of the battery 41 via the capacitor 50. A resistor 51 and an npn-type transistor 52 are connected in series between the base of the transistor 48 and the negative electrode of the battery 41.

The other treatment electrode 14b is connected to the negative electrode of the battery 41 via a parallel circuit of the resistor 53 and the diode 54, and is also connected to the base of the npn-type transistor 55. The emitter of the transistor 55 is connected to the negative electrode of the battery 41.

Further, a power supply circuit 61 that can be opened and closed is provided from the one treatment electrode 14a to the stimulation pulse generation circuit 44. That is, the pnp-type transistor 62 is connected between the one treatment electrode 14a and the connection point of the diode 43 and the coil 45. The base of the transistor 62 is connected to the negative electrode of the battery 41 via the npn type transistor 64.

Although not shown, the stimulation pulse generation circuit 44
Has a microcomputer as a control means. 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 to the output port of the microcomputer. Further, the transistor is connected to an input port of the microcomputer.
55 collectors (point d) are connected. The transistor 55 is for detecting whether or not the treatment electrodes 14a and 14b are connected to the human body.

Further, although not shown in the circuit diagram of FIG. 1, the power switch is connected, for example, between the battery 41 and the diode 43. This power switch is not always necessary, but in order to prevent minute power consumption and careless stimulation when not in use,
It should be there.

On the other hand, in the storage case 21, both case electrodes 24
The battery 71 and the diode 72 are connected in series between a and 24b. The battery 71 is, for example, four AA dry batteries connected in series, and has an electromotive force of, for example, 6V.
It is larger than the electromotive force of the battery 41 of the low frequency treatment device main body 11. The case electrodes 24a and 24b are connected to both electrodes of the output jack 25, respectively.

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

As shown in FIG. 2, when performing a treatment in which the area of the treatment electrode is small and the distance between the pair of treatment electrodes is small, the low frequency treatment device main body 11 removed from the storage recess 22 of the storage case 21 as shown in FIG. A pair of treatment electrodes consisting of adhesive pads 14
Treatment is performed by attaching a and 14b to the skin and directly mounting the low frequency treatment device main body 11 at a desired position on the human body.

Then, first, a high-frequency boosting oscillation signal is output at point a. As a result, the transistor 46 is repeatedly turned on and off, but the coil 45 generates a high voltage on the collector side when the transistor 46 is turned off. Thus the battery 41
Is boosted, and the generated high voltage is charged in the capacitor 50 via the diode 47 for preventing backflow. By repeating this, the charging voltage of the capacitor 50 is sufficiently increased. Even if the transistor 62 is turned on at this time, no current flows in the power feeding circuit 61 due to the directivity of the connection of the transistor 62.

Then, the signal to point c, which had been LOW until then, temporarily goes HIGH, and the transistors 52 and 48, which were previously OFF, are turned ON. This allows the condenser 5
The high voltage charged to 0 is applied as a stimulation pulse to the human body through the transistor 48, the resistors 49, 53 and the treatment electrodes 14a, 14b. That is, a current flows between the pair of treatment electrodes 14a and 14b through the human body. When the signal to the point c is HIGH, the signal to the point b is LOW and the transistors 62 and 64 are off.

This is repeated, and the stimulation pulse is repeatedly applied to the human body at a low frequency to treat muscle pain, stiff shoulder, and the like. By operating the adjustment button 15, the intensity of the stimulation pulse can be adjusted.

After the treatment, the treatment electrodes 14a and 14b 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 bottom of the low frequency treatment device main body 11 is a storage case 21.
The storage recess 22 is formed so as to face the inner bottom surface of the storage recess 22.
Insert inside and store. In this stored state, both treatment electrodes 14a, 14b of the low-frequency treatment device body 11 are directly attached to both case electrodes 24a, 24b in the storage case 21, respectively. By the way, when the low-frequency treatment device main body 11 is stored, the operator 13 of the power switch fits in the notch 23 of the storage case 21, which allows the low-frequency treatment device main body to be housed in the storage recess 22.
The directionality of the fitting of 11 is regulated, and the polarity of contact between both treatment electrodes 14a, 14b and both case electrodes 24a, 24b will not be wrong.

When the low-frequency treatment device main body 11 is stored and stored in the storage case 21 as described above, dust does not adhere to the treatment electrodes 14a and 14b formed of adhesive pads, and the treatment electrodes 14
It is possible to prevent a and 14b from accidentally sticking to something.

In addition, when the treatment electrode is to be enlarged or the distance between the pair of treatment electrodes is increased to perform the treatment, the low frequency treatment device main body 11 is stored in the storage case 21, and the output jack of the storage case 21 is stored. The plugs 35 of the separate conductors 31a and 31b are connected to 25, and the pair of separate conductors 31a and 31b are attached to appropriate positions on the human body to perform treatment. These separate conductors 31a, 31b are treatment electrodes 33a, 33b composed of the adhesive pads.
Is attached to the skin, or is attached to the human body by a band or a plaster. If the treatment electrodes 33a and 33b are adhesive pads, they can be easily attached to the human body. Even when the low-frequency treatment device main body 11 is stored, since the operator 13 and the adjustment button 15 of the power switch are exposed, they can be operated.

At this time, the stimulation pulse generated by the stimulation pulse generation circuit 44 in the low frequency treatment device main body 11 is the same as the low frequency treatment device main body 11
Treatment electrodes 14a, 14b, case electrodes 24a, 2 contacted therewith
4b, output jack 25, plug 35 and leads 34a, 34b
Via the treatment electrodes 33a, 33b of the separate conductors 31a, 31b, to the human body.

At that time, during the period in which the boosting oscillation signal is output to the point a and the capacitor 50 is charged, the signal to the point b becomes HIGH, the transistors 62 and 64 are turned on, and the power feeding circuit 61 is turned on.
Closes. Therefore, from the battery 71 in the storage case 21 outside the low frequency treatment device main body 11 to the low frequency treatment device main body 11 via the case electrodes 24a and 24b, the treatment electrodes 14a and 14b of the low frequency treatment device main body 11 and the power supply circuit 61. Power is supplied to the stimulation pulse generation circuit 44 therein. Moreover, the battery 71 of the storage case 21 has a higher voltage than the battery 41 of the main body 11 of the low frequency treatment device, and the diode 43 for preventing backflow is provided.
A battery is supplied to the stimulation pulse generation circuit 44 only from 71, and no power is supplied from the battery 41 of the low frequency treatment device main body 11.

Further, when the signal to the point c becomes HIGH and the capacitor 50 is discharged, the signal to the point b falls to LOW, the transistors 62 and 64 are turned off, and the power feeding circuit 61
Opens. Therefore, the stimulation pulse current does not flow to the power feeding circuit 61, but flows from the treatment electrodes 33a and 33b of the separate conductors 31a and 31b to the human body. At that time, the diode 72 in the storage case 21 prevents the stimulation pulse from being applied to the battery 71.

After the 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 and the separate conductors 31a and 31b are stored separately so as not to get in the way when not in use. You can also

According to the above configuration, not only can the low-frequency treatment device main body 11 in which the treatment electrodes 14a and 14b are integrally provided be used to perform a simple low-frequency treatment, but also the separate conductor 31a as necessary. , 31
b can be used appropriately to enhance the therapeutic effect. That is, by using the separate conductor 31a, 31b, which has a large area of the treatment electrodes 33a, 33b and can freely increase the distance between the treatment electrodes 33a, 33b, it is possible to expand the treatment site in the human body. As a result, effective stimulation can be obtained even when treating a site where it is difficult to obtain a stimulating sensation such as a foot. In this way, various treatment targets can be dealt with.

By the way, conventionally, in a microminiature low-frequency treatment device, since the treatment electrode is generally made of an adhesive pad, a storage case for storing the treatment device body or a storage plate detachably attached to the treatment electrode, etc. It was an accessory that required some kind of storage. However, according to the above configuration,
Treatment using only the low-frequency treatment device main body 11 and separate conductor 31
In order to enable both treatments using a and 31b, we used the storage case 21, which is a necessary component of the ultra-small low-frequency treatment device, so it is sufficient to make a slight design change to this storage case 21. , The whole structure is simple and can be cheap. At the same time, the existing separate conductors 31a and 31b can be used as they are, which is advantageous in manufacturing and highly convenient for the user. Also, the low-frequency treatment device main body 11 can be a conventional one with almost no design change.
Of course, when using the separate conductors 31a and 31b, the main body of the low frequency treatment device separate from the conventional conductor is not required.

Also, the battery 41 of the low frequency treatment device main body 11 has a small capacity,
When performing treatment using the separate conductors 31a and 31b, the storage case 2
Power is supplied from the battery 71 of 1 to the stimulation pulse generation circuit 44 of the low frequency treatment device main body 11, so by backing up this power supply, the consumption of the battery 41 of the low frequency treatment device main body 11 can be saved, and the battery 41 The life is extended, and the labor for replacing the battery 41 is reduced.

Although the diode 43 is not always necessary,
Due to the presence of this diode 43, the separate conductors 31a, 31b
During treatment using, the power can be supplied only from the battery 71 of the storage case 21.
The consumption of the battery 41 can be saved more effectively.

By using a separate conductor, it is possible to perform treatment by appropriately separating a plurality of treatment electrodes, and it is possible to improve the treatment effect even when treating a site where it is difficult to obtain a stimulating sensation such as a foot. Moreover, it is possible to use the conventional low-frequency treatment device main body and the separate conductor as they are, and since the stimulation pulse generation circuit is common to both treatment forms, the structure can be simplified and it is advantageous in manufacturing.
