The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:

In accompanying drawing 1,2, fixed installation power supply indicator 2, signal output indicator 9 and panel 3 on the box body 1, battery main switch 5, signal output knob 6, power supply conversion knob 7 and signal frequency knob 8 are installed on panel 3, circuit board 13 is fixed in the box body 1, which is provided with branch voltage rectifier, pulse generating circuit and impulse output circuit, battery 11 is housed in box body 1, lid 10 is contained in the bottom of box body 1, and attaching plug 12, therapeutic electrode 4 are connected on respectively on binding post a, the b and e, f of circuit board 13.

In accompanying drawing 3, voltage rectifier was by transformator T in described minute ₂, commutation diode D ₂, D ₃, D ₄, D ₅Bridge rectifier of being formed and filter capacitor C ₁Form; This transformator T ₁Primary coil L _ATo be connected on binding post a, the b of circuit board 13 respectively last and be communicated with its secondary coil L with attaching plug 12 at two ends _BLink to each other above-mentioned filter capacitor C respectively with the brachium pontis of above-mentioned bridge circuit ₁Be connected on another brachium pontis of bridge circuit.Like this, AC signal has just become direct current signal after the rectification blood pressure lowering.Described pulse generating circuit is by large power triode BG ₁, adjustable resistance R ₂, capacitor C ₂And pulse transformer T ₂Primary coil L ₁, L ₂, L ₃Constitute; This adjustable resistance R ₂With above-mentioned primary coil L ₃, capacitor C ₂And primary coil L ₁Series connection, above-mentioned audion BG ₁Base stage be connected on capacitor C ₂With primary coil L ₃Between, its colelctor electrode and primary coil L ₂An end link to each other primary coil L ₁The other end and primary coil L ₂The other end be connected in parallel on adjustable resistance R ₂Left end, resistance R ₂Left end and audion BG ₁Emitter stage be connected on capacitor C respectively ₁Two ends with formation in parallel.Described impulse output circuit is by being connected in parallel on pulse transformer T ₂Secondary coil L ₄The adjustable resistance R at two ends ₃Constitute this secondary coil L ₄To be connected on binding post e, the f of circuit board 13 by lead fixed last and link to each other with therapeutic electrode 4 at two ends.In order under the situation of no civil power, to use, can a direct current power supply E in parallel between minute voltage rectifier and the pulse generating circuit, between above-mentioned two circuit tandem tap K ₂, K ₁In order to grasp the running status of instrument at any time, can be at bridge circuit and secondary coil L _BBetween running fire optical diode D ₁, at audion BG ₁Emitter stage, base stage between connect light emitting diode D ₂

Adjustable resistance R ₂Be connected adjustable resistance R accordingly with signal frequency knob 8 ₃Be connected light emitting diode D with signal output knob 6 accordingly ₁, D ₂Correspond respectively to power supply indicator 2, signal output indicator 9, dc source E is corresponding to battery 11, K switch ₂, K ₁Correspond respectively to power supply conversion knob 7, battery main switch 5.

During use with the docile and obedient place, acupuncture point in human body of therapeutic electrode 4 usefulness adhesive plasters, then energized, opening power main switch 5, power supply is changed knob 7 push and exchange shelves.At this moment, power supply indicator 2, output indicator 9 build-ups of luminance are luminous, and the expression instrument is working properly.Electric current is through becoming direct current to powering to pulse generating circuit behind the rectifying and wave-filtering, electric current is through primary coil L ₃Trigger triode BG ₁Conducting makes capacitor C ₂With primary coil L ₁Between be able to continually to dash electricity, discharge and form vibration, its frequency of oscillation is 10---120 time/minute; Electric current is through primary coil L simultaneously ₂, colelctor electrode, emitter stage form the closed-loop path and at primary coil L ₂Middle generation frequency is 10---120 time/minute variation magnetic field, thereby at secondary coil L ₄In induce two sharp wave pulse signals of same frequency, and directly act on human acupoint by therapeutic electrode 4.Conditioning signal frequency knob 8 can make adjustable resistance R ₂Resistance changes, primary coil L ₃Change in voltage is fed back to audion BG ₁Base stage, make primary coil L ₁And capacitor C ₂Frequency of oscillation change, thereby cause secondary coil L ₄The two sharp wave pulse signals that induce change in the scope of 0---40V thereupon.For example: during 0---10V, can in human body, produce acupoint in the similar acupuncture and moxibustion therapy process, and make meridians produce dancing sensation; During 10---40V, can in human body, produce the sensation that promotes meridians, blood vessels shuttling movement in the similar qigong and the massage treatment process.Conditioning signal output knob 6 can make adjustable resistance R ₃Resistance changes, and causes the electric current in the therapeutic electrode 4 to change, thereby changes the intensity of two sharp wave pulse signals.When power supply was changed knob 7 and pushed zero frequency span, power supply indicator 2 extinguished, output indicator 9 build-ups of luminance are luminous.
