The electrotherapy is matched with hot compress magnetic therapy at the same time. Clinical application shows that the utility model has satisfactory curative effects on a plurality of diseases such as arthritis, acute soft tissue contusion, etc.

Description

Multifunctional musical electrotherapy instrument

This utility model relates to a kind of electronic physiotherapeutic device that is used for body-care, treatment.

The acupuncture point of the electric pulse stimulation human body that produces with the electronics physical therapy device with reach treatment, the purpose that keeps healthy, clinical practice is confirmed this mechanism by Chinese and western medicine.Be the fidgety emotion of avoiding patient in the physical therapy process and the human body adaptation inertia to the treatment pulse current, the someone adopts the synthetic method of music VF, and the electric current that makes instrument output constantly changes with the rhythm and pace of moving things intensity of melody.The patient listens to the melody of liking when receiving treatment, can adjust brain function and mental status, reduces dull sense and adapts to inertia.But existing music electrotherapeutic instrument can only be exported the sine wave of density impulse wave, intermittent pulse ripple or the FMAM of simple modulating frequency.Sinusoidal wave energy is strong not as impulse wave, so zest is weak, curative effect is not remarkable; Too fierceness, weak patient are difficult to bear and through the synthetic density of music audio signal, intermittent pulse ripple, variation.

The purpose of this utility model is to overcome above-mentioned shortcoming, a kind of music electrotherapeutic instrument that can carry out variable electrotherapy, hot compress and magnetic therapy simultaneously is provided, the amplitude and the frequency of the rectangle treatment pulse of its output can choose at random a suitable datum quantity by patient, carry out FMAM control with music signal then.

For reaching this purpose, this utility model adopts voltage controlled oscillator, dutycycle initialization circuit to produce the less benchmark rectangular pulse of dutycycle, by fundamental frequency initialization circuit and output intensity regulating circuit frequency (fo) and amplitude (Vo), make the suitable quantity of stimulus of treatment electric current maintenance by the manual selection reference pulse of patient.Audio signal by audio frequency rectification circuit and amplification regulating circuit output is carried out Variable Control to the Frequency and Amplitude of reference pulse, producing frequency is fo ± △ f, amplitude be Vo ± △ V with the strong and weak treatment pulse current that changes of music rhythm, overcome the dullness sense in treating and the mutability of pulse energy.By the output signal control magneto-thermoelectric source of audio amplifier circuit, the heating current that changes, produce the magnetic field that changes with music signal by the magnetic therapy hot application device and in electrotherapy, carry out the hot compress magnetic therapy simultaneously.

Now in conjunction with the accompanying drawings this utility model is described in detail.

The audio signal that obtains from PA-system pickups such as radio cassette players is divided two-way output after becoming unidirectional pulsating current by audio frequency rectification circuit (1) rectification, difference control impuls power circuit (3) and voltage controlled oscillator (7) after one route audio frequency amplification regulating circuit (2) amplifies, the control signal that provides Frequency and Amplitude constantly to change. The centre frequency fo of voltage controlled oscillator (7) regulates by fundamental frequency initialization circuit (6) is manual, its pulse width is controlled by dutycycle initialization circuit (9), behind audio signal frequency modulation, exported by pulse-switching circuit (8), the amplitude-modulated signal of same pulse power supply circuit (3) output inputs to pulse boostering circuit (4) together, through output intensity regulating circuit (5), regulated voluntarily by the patient, obtain satisfied pulse current and enter human body by electrotherapy electrode (14). Another road output control magneto-thermoelectric source (11) after audio amplifier circuit (10) amplifies of audio frequency rectification circuit (1) is adjusted suitable heating current input hot compress Magnetotherapeutic apparatus (13) by magneto-thermoelectric stream adjusting (12) then and is made hot compression therapy. The heating wire of hot compress Magnetotherapeutic apparatus (13) turns to specific coil shape, therefore when the alternation heating current of music signal control passes through, with the magnetic fields that changes around in human body.

Characteristics of the present utility model be electrotherapy output be the smaller rectangular wave pulse of duty, can because of people due to illness frequency and the amplitude of selection reference pulse, make treatment injure remain that one relaxes Suitable stimulation energy is added on this basis music signal and is modulated, the sudden change in avoiding treating or energy excessively a little less than. In electrotherapy, also can carry out the hot compress magnetic therapy to the affected part, its magnetic field intensity also can change with the strong and weak rhythm and pace of moving things of music signal. In addition, the turn-off pulse circuit then can carry out the happy frequently electrotherapy of absolute music control, output frequency modulation sine wave; Do not add pickup signal and then can carry out the electrotherapy of low frequency constant amplitude pulse, the output weighing apparatus is pulse current frequently.
