Description

Can control the strong and weak treatment contact of therapeutic instrument output

This utility model relates to a kind of when carrying out health therapy to oneself, can the oneself control the treatment contact of exporting signal of telecommunication power, is the accessory of electronic therapeutic instrument.

Electronic therapeutic instrument is as one and the health therapy apparatus, enter huge numbers of families, played the effect of " family health care doctor ", convenient, quick-acting, liked by the masses, but because the treatment head hand-helds that adopt, both hands must be held the operation of attacking a vital point of treatment head during treatment, and can't oneself's control treat signal of telecommunication power more, therefore, oneself can not carry out health therapy to oneself, needs to rely on other people to help, and uses inconvenience.Haihua Applied Technology Development Co., Ltd., Dandong discloses a kind of adhesive treatment contact that is composited by conductive viscose layer, conductive substrate and insulating barrier in ZL93229269.0; during use; stick on the human body therapy acupuncture point fixing by the conductive viscose layer; thereby both hands have been liberated; can carry out Heal Thyself; its weak point is, it is strong and operation is not nimble that contact sticks on the acupuncture point pressure sensitivity, is difficult for obtaining optimum therapeuticing effect.

The purpose of this utility model is to provide one and simple in structure, and is easy to use, can control the strong and weak treatment contact of therapeutic instrument output when carrying out health therapy to oneself

Technical solution of the present utility model is: comprise handle, be fixed on handle end electrode slice, be welded on the hand-held contact that the lead on the electrode slice is formed, it is characterized in that also comprising and to be connected between therapeutic instrument signal source and the effect level, well can substitute the keying formula electronic sound volume potentiometer of former potentiometer work, and key switch is installed on the handle.

When this utility model uses, as long as keying formula electronic sound volume potentiometer being connected between the input of the outfan of therapeutic instrument signal source and effect level is alternative former potentiometer work, and by being installed in the power of the key switch control therapeutic instrument output signal on the handle.When both hands are held treatment contact are carried out acupuncture therapeutic, can the oneself adjust the therapeutic instrument output signal, it is nimble not only to have kept the operation of hand-held treatment contact, can adjust the advantage of acupuncture point and pressure sensitivity at any time, can also adjust the signal of telecommunication according to the personal experiences oneself who stimulates, make power reach optimum, thereby can improve the therapeutic effect of therapeutic instrument, obtain optimum curative effect.In a word, the utlity model has simple in structure, can improve curative effect, advantage easy to use.

Following accompanying drawing has been described embodiment of the present utility model.

Fig. 1 is a structural representation of the present utility model;

Fig. 2, Fig. 3, Fig. 4 are electrical schematic diagram of the present utility model.

Below in conjunction with accompanying drawing this utility model is described in detail.

This utility model is on the basis of existing hand-held treatment contact, be provided with the keying formula electronic sound volume potentiometer that can be connected between therapeutic instrument signal source and the effect level and can replace the former potentiometer work of gas, Fig. 2, Fig. 3, shown in Figure 4 be the electrical schematic diagram of electronics chapter amount potentiometer.

Keying formula electronic sound volume potentiometer is by field effect transistor BG among the embodiment shown in Figure 2 ₁, key switch K ₁, K ₂And Resistor-Capacitor Unit is formed field effect transistor BG ₁Source S pass through resistance R ₄Connect ground terminal d, drain D is passed through resistance R ₃Connect positive terminal a; Capacitor C ₁Be connected between grid G and the ground terminal d key switch K ₂With resistance R ₂Series connection also is connected between grid G and the ground terminal d; Key switch K ₁With resistance R ₁Series connection also is connected between grid G and the positive terminal a; Pass through capacitor C from drain D ₂Draw terminals b, draw terminals c from source S; Key switch K ₁, K ₂Be installed on respectively on the handle of two contacts, wherein field effect transistor BG ₁Adopt 3DJ ₆When present embodiment uses, positive terminal a and ground terminal d are connected the both positive and negative polarity of therapeutic instrument power supply respectively, terminals b connects the outfan of therapeutic instrument signal source, terminals c connects the input of therapeutic instrument power amplifier level, make it to substitute former potentiometer W work, the signal of telecommunication that the therapeutic instrument signal source produces is through field effect transistor BG ₁Be transported to the power amplifier level.Field effect transistor belongs to voltage-controlled component, and when it works in the adjustable resistance district, its drain-source interpolar electricity sun will be subjected to the i.e. capacitor C among the figure of gate-source voltage ₁Both end voltage control is equivalent to voltage-controlled variable resistance.Make key switch K when pressing the control button ₁During conducting, power supply will pass through resistance R ₁To capacitor C ₁Charging makes it both end voltage and raises field effect transistor BG ₁Internal resistance reduce, signal strengthens, the therapeutic instrument output intensity increases, if push button K switch ₂Make it conducting, then capacitor C ₁To pass through resistance R ₂Discharge makes it both end voltage and descends field effect transistor BG ₁Internal resistance increase, signal weakening, the therapeutic instrument output intensity reduces.Like this can be by being installed on the key switch K on the handle ₁, K ₂, indiscriminately ad. as one wishes control the power of therapeutic instrument output signal.

Among the embodiment shown in Figure 3, keying formula electronic sound volume potentiometer is by field effect transistor BG ₂, key switch K ₁, K ₂And resistor-capacitor unit is formed field effect transistor BG ₂Drain D pass through resistance R ₈Draw terminals b, pass through capacitor C ₃Draw terminals c; Key switch K ₂With resistance R ₆Series connection also is connected between grid G and the positive terminal a; Draw ground terminal d, capacitor C from source S ₂Be connected between grid G and the ground terminal d key switch K ₁And resistance R ₇Series connection also is connected between grid G and the ground terminal d; Key switch K ₁, K ₂Be installed on respectively on the handle of two contacts.Field effect transistor BG wherein ₂Adopt V20AT.When present embodiment used, positive terminal a was connected the therapeutic instrument power positive cathode respectively with ground terminal d, and terminals b connects the outfan of therapeutic instrument signal source, and terminals c connects the input of therapeutic instrument power amplifier level.As previously mentioned, field effect transistor BG here ₂Be equivalent to pressure-controlled variable resistance, it and resistance R ₃Formed the electric resistance partial pressure type attenuator circuit, the signal that the therapeutic instrument signal source is produced is transported to the power amplifier level, can substitute former potentiometer W work.When the K switch that pushes button ₂When making it conducting, power supply is to capacitor C ₂Charging makes it both end voltage and raises, and the internal resistance of field effect transistor drain-source interpolar diminishes, signal weakening, and the therapeutic instrument output intensity reduces, and K switch pushes button ₁The time, make capacitor C ₂Discharge makes it both end voltage and descends, and the field effect transistor internal resistance increases, and signal strengthens, and the therapeutic instrument output intensity increases.Thereby can pass through key switch K ₁, K ₂The output of oneself's control therapeutic instrument is strong and weak.
