Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a low frequency therapy device structure that can be used by directly attaching it to the human body.

Conventionally, transcutaneous electrical stimulation devices, that is, so-called low-frequency treatment devices, have been provided and used in sizes that are portable enough to be used; However, as with bandages, poultices, etc., no one has yet been proposed that has a structure that allows it to be attached integrally to the skin.

Therefore, the main object of the present invention is to overcome the difficulties of these known techniques and to provide a novel low-frequency treatment device structure that is extremely easy to fabricate and light in weight, and can be directly attached to the skin of the human body.

Hereinafter, specific examples of the low frequency treatment device structure of the present invention will be described in detail.

(Frequency Power Supply Uni, 7) The low-frequency power supply unit of the present invention (hereinafter abbreviated as power supply unit) is a combination of a small and lightweight battery and a low-frequency pulse output means driven by the battery, either integrally or separately. As the low-frequency pulse output means, a conventional low-frequency treatment device that is made smaller and lighter by hybridization, IC, etc. is sufficient, but particularly preferred circuit configurations are as follows. .

FIG. 1 is a block diagram showing an embodiment of a power supply unit suitably used in the low frequency treatment device structure of the present invention, and FIG. 2 is a waveform diagram of each part in FIG. 1. Here, the unit includes a boost pulse generating means A constituted by an oscillating section 11 and a boosting section 12;
The M ridge part (storage means) 13, the output means B constituted by the switch control part 16 and the switch part 14, the depolarization part (depolarization means) 15, the small power source and the output terminal,
The waveform of the output terminal a of the boost pulse generating means A is as shown in FIG.
(1), the output end C of the output means B corresponds to FIG. 2(c), and the output between the output terminals K and F corresponds to FIG. 2(d). The output of the oscillation f311 that oscillates pulses in a free-running manner generates a boosted pulse in which the amplitude value of the pulse is boosted several times in the boosting section 12. As shown in Fig. 2(a), the boost pulse has a pulse width of, for example, 1 (μsec), approximately 2, S (kllz
) is output as a pulse wave-like pulse and input to the storage section 13. The storage section stores pulse wave-like pulses as shown in FIG. 2(b). When the predetermined potential is reached, the switch control section 16 outputs a control signal to the switch section 14 to discharge the accumulated charge in the accumulation section 13. When the potential reaches a certain level, the switch control section 16 stops outputting the control signal, so the switch section becomes OFF, and the output of the output means B has a pulse width of, for example, 0.3 as shown in FIG. 2(c). (msec)
, outputs a low frequency pulse of approximately 5 (llz). This 1 degree frequency pulse is applied to the tissue of the living body 11 through the Kan conductor, but at the falling edge of the low frequency pulse, the polarized charge generated in the living tissue is discharged through the depolarization section 15, as shown in FIG. (
The waveform diagram is shown in C).

Incidentally, the pulse width and frequency of the oscillation pulse oscillated by the boost pulse generation means in the present invention can be appropriately selected depending on the output frequency and pulse width of the switch control section (output means) installed at the subsequent stage, but usually 1. ~ several hundred (kllz).

Next, each technical element of this example will be explained in detail.

1. Small power source The small power source shown in this example uses one or more button-type batteries, sheet-type batteries, coin-type batteries, cylindrical batteries, pin-type batteries, etc. Although the shape is not particularly limited, a small, thin, and lightweight battery is preferred. Further, a small rechargeable button-shaped secondary battery or the like may be used.

Boosting pulse generating means The boosting pulse generating means is a combination of an oscillator such as an astable multi-by-break and boosting means such as an inductor, a transformer, or a charge pump type boosting circuit.
Alternatively, it may be constituted by an oscillator that integrally has an external pressure function, such as a pronking oscillator. That is, the free-running bronking oscillator is formed by three coils provided in the circuit as shown in FIG. 3, and the turn ratio of the output fill 1 and the intermediate coil L2 is as follows.
The peak voltage of the pulse on the output side is I with respect to the power supply voltage E1
yields El. Therefore, it is possible to easily change the boost amount by changing the number of turns of the output side coil.

Furthermore, since the pulse peak of the output of the free-running blocking oscillator is not constant, it is possible to output a pulse with a constant peak amplitude by setting a constant voltage element at the output terminal. The amount of boost can be adjusted by changing the number of turns as described above. The pulse period T oscillated by the blocking oscillator is determined by the resistor Rb and capacitor C1.
is approximately equal to the product of On the other hand, a boost pulse can also be oscillated by a blocking oscillator as shown in FIG.
2 is a more preferred embodiment of a boost pulse generating means in which a boost pulse is oscillated by the back electromotive force generated by the switching operation of a transistor, and the number of elements can be reduced. It is shown in figure (c).

3. U means and output means The storage means and output means in the present invention consist of two means: means for accumulating electrical energy such as external pressure pulses output from the boost pulse generating means, and means for outputting M-product charges. The pulse width of the pulse drawn by the discharged charge is set depending on the accumulated amount. The above means includes a switch control section that compares the amount of charge in the storage means with a predetermined threshold voltage and outputs a signal when the predetermined threshold voltage is exceeded; The output means is formed by the configuration with the switch part that discharges the electric charge, but as a circuit with fewer elements, the negative resistance element N connected in parallel with the capacitor C is used as shown in the figure. can be shown. The boost pulse charged by the capacitor C1 and the resistor R2 with the C and R time constants gradually increases the voltage between the terminals of the negative resistance element, which is determined by the unique value of the negative resistance element or by the resistor R1. When the voltage reaches the specified voltage, the capacitor C becomes conductive, and the voltage stored in the capacitor C is discharged through the negative resistance element i4, and becomes non-conductive at the lower limit value specific to the negative resistance element.

More specifically, if the pulse width is 1 from the input part IN in FIG.
When a boost pulse with an amplitude of 24 (~゛) in (μsec) is input at a frequency of 1 to several hundred (kllz), the capacitor C is set to 1 (μF) and the M product is increased until the negative resistance element N becomes conductive. The conduction time of the negative resistance element N is approximately 0,3
By outputting one low frequency pulse with an amplitude of 24 (\・') at (+n5ec) and repeating this, a frequency of 5
(llz), a pulse width of 0.3 (1rlsec), and an amplitude of 24 (V).

As described above, the configuration of the negative resistance element, capacitor C1, and resistor R constitutes a relaxation wave oscillator, and since the oscillation pulse discharges the charging type and load of the capacitor C, a high-energy pulse can be obtained. This negative resistance element is also an electric current limiting resistance element, and is a UJT (unijunction transistor), Cybook, PUT (programmable unijunction transistor Lll type 5
Since CR (Cyrisk) etc. are preferably used, it is not particularly limited to one. In addition, using a relaxation wave oscillator using a negative resistance element as a switching means to control the charging/discharging voltage of the storage means is an extremely suitable implementation, as it can generate periodically stable low-frequency pulses. 8, and its specific configuration is shown in the circuit of FIG.

It should be noted that whether a sufficient accumulation amount is required to generate a stimulation current or not can be freely adjusted depending on the capacity of the accumulation means, etc., and the discharge start voltage and discharge stop voltage are determined by the characteristic value of the negative resistance element or the negative resistance. Resistance element (determined by the time constant of the relaxation wave oscillator configured thereby).

In addition, in the case of PUT, the conduction start voltage of PUT can be determined by the resistance value attached to the 7-made side.
Preferably used.

The storage means may be anything that has the function of multiplying electrical energy by M, such as a capacitor, a storage diode,
The pulse to be applied using an inductor etc. is shown in Figure 6 (
As shown in Figure 6(b), when there is a rectangular pulse wave, the residual charge (polarized charge) in one living tissue appears in the state shown in Figure 6(b), and when the period is made small, the residual charge Electricity is blocked and the sensation of stimulation is minimal. Moreover, when the voltage value of the applied pulse is low, the influence of polarization is large.

Therefore, the depolarization means in the present invention can be constructed by providing means for short-circuiting the related inductor and the indifferent inductor at a predetermined time in the interval of applied pulses, or by arranging a resistor having a predetermined resistance value. Can be r&. The short-circuiting means may be set to operate only at a predetermined time interval; for example, the switching operation of a transistor may be used to set the state in which fJl1mON is turned on at a predetermined time. With the above configuration, the 6th
An output as shown in Figure (c) can be generated. Furthermore, if the resistor is set to a value that takes skin resistance into consideration, it will operate satisfactorily even if it is always placed, and this is a preferred embodiment in terms of miniaturization. This resistor is approximately 100 (
(kΩ) or less is suitable. Further, the pulse interval indicates the period from the falling edge of a pulse to the rising edge of the next pulse, and the depolarization operation is preferably performed at the falling edge of the pulse.

Furthermore, as an example of a pond as a depolarizing means, a resistor and a short-circuit condition may be set, and instead of discharging on the circuit side, the polarized charge may be recovered and used as part of the power supply voltage. This will reduce power consumption and enable longer usage times.

The seventh embodiment describes the embodiment for recovering the polarization voltage as described above.

R is a load indicating skin impedance.

The low-frequency pulses outputted via 71, 72, and 73 pass through the switching means 75, the primary side of the transformer, and the inductor K, and are applied to the load. When the pulse falls, the second switching means 75 is turned OFF and the first switching means is turned ON, and the polarized charge generated by the pulse applied to the load R is discharged via the first switching means. A voltage is induced on the secondary side of the diode 76, and a current flowing due to the induced voltage flows through the diode 7.
7 and is recovered to the power supply 71.

In addition, in the case where the polarization voltage becomes higher than the power supply voltage, the polarization voltage recovery means in the present invention may include connecting separate batteries in parallel to the power supply side, changing the number of turns of the transformer, or using a voltage drop means using a resistor in the middle. may be selected as appropriate.

One end of the secondary fill of the transistor 84 is grounded, and one end of the pond is connected to the base via the capacitor 81. Furthermore, a resistor 82 is connected between one end of the power supply 80 and the bottom part to constitute a blocking oscillator (boost pulse oscillation section). The collector side of the transistor 83 serves as an output terminal, which is connected to one end of a capacitor 86 via a diode S5, and further connected to an output terminal K. Further, one end of the capacitor 86 is connected to a PUT (programmable unijunction).

The back electromotive force of the transformer 84 generated at this time is applied to the external voltage 25 (\') and input to the capacitor 86 via the diode D. Since the diode D prevents the discharge of the accumulated charge to the boost pulse oscillator, the accumulated charge of the capacitor 86 increases and at the same time, the potential of the capacitor 8C in the relaxation oscillator including the PUT rises, and the PUT becomes conductive. At this time, the charge in the capacitor 8C is discharged and transferred to the base side of the transistor 88, and the transistor 88

Further, by outputting such a deformed wave aperiodically, it may be adapted to various forms of stimulation felt by the human body, and the amplitude, period, waveform, etc. of the output pulse may be selected as appropriate.

First, the conductor structure of the present invention will be explained in detail based on one embodiment shown in the attached FIGS. 14 and 15.

In the figure, the conductor 302 is made of paper material such as water-absorbing paper, cloth material such as gauze, etc.
A conductive member layer 305 for current dispersion made of a fiber material such as absorbent cotton, a sponge or porous material such as an open synthetic resin foam or a water-absorbing resin, etc., and a skin formed around the water-absorbing member 304. It consists of a hydrophilic adhesive or gel layer 3011 having adhesive properties and a backing layer 3010 such as a synthetic resin film laminated integrally thereon.

Here, the conductive member layer 305 may be a backing layer formed by vapor-depositing metal such as aluminum, and appropriate terminals may be provided as required. Furthermore, a barrier layer 3012 made of a synthetic resin material or the like may be provided between the hydrophilic gel layer 304 and the water-absorbing member 304 in order to prevent a chemical solution from penetrating the gel.

The conductor of the present invention having the above-mentioned configuration has its water absorbing member 30
4 is impregnated with an ionic solution or the like, or the member that has been impregnated in advance is placed in a predetermined position, inserted, and directly adhered to the skin for use. Therefore, when in use, the structure in which the electrolyte holding part is surrounded by a skin-adhesive and hydrophilic gel layer increases the appropriate water absorbency of the gel layer.
According to the conductor of the present invention, an ideal electrolyte holding portion that does not require complicated fixing means such as a band and effectively prevents the solution from flowing out can be achieved at the same time.

Note that FIG. 14 is a plan view of the conductor of the present invention, and FIG. 15 is a sectional view thereof.

Hereinafter, embodiments of the structure of the present invention that also utilize the above conductor structure will be described in detail with reference to FIGS. 16 to 18. In the figure, reference numeral 301 denotes a structure according to the present invention, which has an inductor 302 and an inductor 303. The Seki Doko 302 is
Paper materials such as water-absorbing paper, cloth materials such as gauze, fiber materials such as absorbent cotton,
A water-absorbing member 304 for impregnating and retaining an electrolyte solution made of a sponge or porous material such as a synthetic resin continuous foam or a water-absorbing resin, a hydrophilic del layer 3011, a metal foil such as sia aluminum foil, or a conductive rubber or resin. It consists of a current dispersion conductive member layer 305 formed of a film or the like.

Further, the insensitive conductor 303 includes a skin-adhesive conductive gel layer 306 formed in the form of a flexible sheet or film, and is made of aluminum as described above. A low frequency power supply 308 is installed on the upper surface of the conductor 302 so that one of its poles, for example, the (-) pole, contacts the current dispersion conductive member layer 305 . Further, the (+) pole of this power supply 308 is connected to the current dispersion conductive material layer 307 of the indifferent conductor 303 by a lead wire 309 made of aluminum foil, for example, whose lower surface except near both ends is coated with an insulator. . 3010 is an insulating backing layer. This insulating backing layer 3010 is made of, for example, a non-conductive synthetic resin formed in the form of a flexible sheet or film.
They are arranged and fixed at 10 intervals. That is, Deiko Seki 302. The insulating conductor 303 and the power supply 308 are integrally supported and connected by the insulating backing layer 3o10. Further, in this example, an insulating synthetic resin barrier layer 30
12 are provided.

Next, the operation and usage of the structure of the present invention constructed as described above will be explained. First, the water-absorbing member layer 304 of the Kando inductor 302 is impregnated with a desired electrolyte or sherry, and then the Kando inductor 302 is attached to a desired position on the human body so as to come into contact with it. At the same time, the inductor 302 and inductor 303 form a closed circuit, and a predetermined energization is achieved.

Although a detailed description has been given of an example in which both conductors are integrally arranged close to each other, there may be cases where it is more convenient to separate the conductor and the conductor from each other depending on the attachment site. Therefore, in the present invention, "integral molding" or "
"Connected in one piece" generally includes not only the case where they are simply arranged in the same packing, but also the case where they are electrically connected.

As is clear from the above, the structure of the present invention has the remarkable effect of allowing effective treatment to be performed with extremely simple operations and safely and reliably without requiring complicated and large equipment. It is.
