Description

Middle frequency unidirectional intermittent pulse therapy apparatus

This utility model relates to the unidirectional intermittent pulse therapeutic instrument of a kind of intermediate frequency, is applicable to diseases such as treatment bromhidrosis, acrohyperhidrosis.

In recent years, have the iontophoretic treatment device production of specially controlling bromhidrosis and hyperidrosis of hand and foot external the sixth of the twelve Earthly Branches, and the electric osmose therapy adopts tap water as conducting solution exactly, and under electric field action, ion enters skin through the sweat gland opening, changes through a series of electrophysiology, suppresses to perspire.Its mechanism that suppresses to perspire is: there is electric potential gradient in (1) along sudoriferous duct, and perspiration is outwards motion successively, and electric osmose may have been destroyed supravasal electric potential gradient, perspiration is discharged be obstructed; (2) it is influenced that iontophoresis may make pore place keratinization process, makes it produce keratotic plug, obstruction, and perspiration can not be discharged, and in (3) iontophoresis process, electric current can produce the neural or local acupuncture point of domination sweat gland to stimulate, and sweat gland secretion is reduced.The part but present iontophoretic treatment instrument also comes with some shortcomings, (1) current forms that adopts at present, be mainly direct current and low frequency pulse current, and according to skin electrophysiology character, should be higher with the curative effect of the unidirectional intermittent pulse electric current of intermediate frequency, side effect such as electricity irritation and electric injury are little, (2) electrode adopts the metal manufacturing, and placing both hands or oxter respectively, electric current passes through from trunk, has potential danger.The metal electrode damage that gets rusty easily in addition; (3) volume is bigger, carries inconvenience, and the individual uses trouble.

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and provides a kind of to utilize the unidirectional intermittent pulse electric current of intermediate frequency to treat and adopt conductive rubber as the unidirectional intermittent pulse therapeutic instrument of the intermediate frequency of electrode.

The purpose of this utility model can reach by following measure: this utility model is made up of power circuit, electrode, shell, it is characterized in that also having the unidirectional intermittent pulse generation of intermediate frequency circuit, adjusting and indicating circuit, the unidirectional intermittent pulse generation of intermediate frequency circuit can produce rectangular wave pulse, this waveform is by electrode 3 outputs, and adjusting and indicating circuit link to each other with the unidirectional intermittent pulse generation of intermediate frequency circuit.The frequency of output waveform can be regulated by the potentiometer W1 in adjusting and the indicating circuit.(2) of the colelctor electrode of BG1 and pulse transformer B secondary coil end links to each other in the unidirectional intermittent pulse generation of the intermediate frequency circuit, and exports pulse thus, and (2) end of base stage and B secondary coil links to each other emitter grounding.Electrode 3 is made up of conductive rubber, sponge, gauze, is lined with one deck sponge on the conductive rubber, is covered with one deck gauze on the sponge, and electrode is installed on the cabinet of complete machine.

Figure (1) is a functional-block diagram of the present utility model;

Figure (2) is an electrical schematic diagram of the present utility model;

Figure (3) is the internal structure sketch map of electrode;

Figure (4) is an outline drawing of the present utility model.

With reference to figure (1), this utility model is made up of power circuit 1, the unidirectional intermittent pulse generation of intermediate frequency circuit 2, electrode 3, adjusting and indicating circuit 4 etc.

With reference to figure (2), power circuit adopts 2 joint 1.5V aneroid battery, and in the unidirectional intermittent pulse generation of the intermediate frequency circuit, B is a pulse transformer, changes its turn ratio and the mode of connection, can raise or reduce pulse amplitude and change pulse polarity.This process utilizes positive feedback to reach.When faint signal increases the BG1 collector current, produce positive feedback by B, the B secondary induction to voltage be added on emitter junction by Cb, the BG1 base flow is strengthened, the afflux of BG1 increases more like this, and this chain reaction is carried out very soon, up to the BG1 saturation conduction, B primary coil both end voltage U1 is near dc source voltage Ec, secondary induction voltage U 2=(N ₂)/(N ₁) Ec, this voltage charges rapidly to capacitor C b by emitter junction.Because the saturated back of BG1 afflux changes and reduces the also very fast disappearance of B secondary induction voltage.Because the polarity of voltage after the Cb charging is a reverse biased to BG1, thereby makes that BG1 is very fast and end that this moment, circuit was in temporary transient steady statue.After this, Cb is determined by R2, W1, emitter junction resistance through base stage equivalent resistance Rb() and the Ec discharge, Ec is to the Cb reverse charge simultaneously.When the discharge of Cb and reverse charge made voltage on the Cb be zero, BG1 produced base flow again, the beginning conducting, and whole process repeats once again.BG1 conducting and the result who ends, outfan just obtains rectangular wave pulse.Output frequency is by Cb, Rb and the decision of transformator character.Adopted a LED as relay indicating light in adjusting and the indicating circuit 4.Regulate W1 and can change defeated frequency, because of skin conductivity amount and electric current sensation relevant with frequency, thereby indirect regulation current intensity.

With reference to figure (3), electrode is made up of conductive rubber 4, sponge 5, gauze 6, and it is contained on the cabinet 2 of complete machine.

With reference to figure (4), 1 is that electrode, 2 is that cabinet, 3 is plastic casing, and circuit board etc. are contained in the plastic casing.Plastic casing causes collapsible shape, when treatment palm or vola, it is spread out, keeps flat, soak electrode with tap water after, hands or foot are put thereon; During the treatment bromhidrosis,, be sandwiched under the axillary fossa 360 ° of its opisthotonos.

This instrument output frequency is 2.4～8KHZ, effective pulse width 3US, intermission 125～420US, peak impulse voltage 65V.

The utility model has following advantage compared to existing technology:

1. output current characteristic meets skin electrophysiology character, and site of action is dark, and curative effect height, side effect are little.

2. volume is little, and is collapsible, is easy to carry, and cost is low, and electrode can not get rusty, not fragile.
