Description

Pocket treatment equipment for tinnitus

Pocket tinnitus therapeutic apparatus is a kind of specific apparatus of treatment tinnitus.Belong to electronic medical instrument field.

Most scholars thinks that tinnitus is due to the spontaneity discharge activity of cochlea or acoustic nerve diseased region.The instrument of treatment tinnitus is called tinnitus masker at present.It is to stimulate with extraneous sound to suppress cochlea or the excited enhanced activity of acous spontaneity.The intensity of sonic stimulation is regulated according to the frequency spectrum of patient's tinnitus and loudness and is matched identical or surpass the pure sound and the noise of 10 decibels of tinnitus, and volume controls greatly between 40～85 decibels.Its shortcoming is that the frequency noise upper limit that instrument sends does not reach 7000HZ owing to the technical device index, therefore, can not treat high frequency tinnitus.In addition, the masking sound duration of a sound time stimulates, and itself can cause tinnitus or deafness, and is harmful.

This utility model purpose is to avoid weak point of the prior art and tinnitus therapeutic apparatus that a kind of positive pressure pulse is provided, thereby it is used rhythmic dull pulse signal and stimulates acoustic nerve and cochlea to suppress the spontaneity discharge activity that diseased region produces tinnitus is eliminated in the stimulation of maincenter.Dull electric-impulse stimulation scope can make the treatment in ear of curer hear the sound that a 500HZ is following below 500HZ, and dull and soft sound can make people's emotion loose, and tinnitus is had inhibitory action, plays the effect of biofeedback.

This utility model is made up of pulse generator and electrode probe.Pulse generator uses dual time-base ic, and this circuit can produce low frequency and intermediate-freuqncy signal, and makes it modulation, and sends the pulse signal below the 500HZ, through level adjustment and amplification output, its amplitude is changed more than zero level.In order to improve output amplitude, in amplification output circuit, added a high-voltage generator, so that enough strong output pulse to be provided.Its high-amplitude can reach more than the 100V.The positive pulse voltage of output makes medicine ion import in ear under enough electric field actions and treats like this.The signal that the pulse 500HZ that sends is following, it is best that human body is accepted, and dull pulse signal stimulates sound can play calm and regulates the effect of patient's emotion.500HZ is with interior electricity irritation, can suppress the excited caused tinnitus of cochlea and acoustic nerve spontaneity discharge and do not cause pain.

This utility model will further be known clearly in conjunction with the accompanying drawings and embodiments.It is low frequency 1HZ and intermediate frequency 400HZ generator that pulse generator uses dual time-base ic IC556 to produce two generators, formed wave group generator (modulation), the pin one of IC556 and foot 6 are connected to resistance R 1/500K, and R2/1M is in the series circuit of R3/500K and capacitor C 2/1 μ.Foot 5 meets power supply+6V by R4/1K, D1, and by D2/2CP and C3/0.1 μ ground connection.Foot 7 ground connection.Foot 4,14,10 meets positive supply+6V, and foot 13 connects power supply by R5/1K, is connected with foot 12, foot 8 by R6/15K, R7/150K serial connection back to connect C3/0.1 μ ground connection again.Outfan foot 9 connects potentiometer R8/4.7K ground connection after meeting capacitor C 4/4.7 μ.The variable outfan of R8 inserts amplifier tube Q3/3DA87C base stage by R9/10K and amplifies.Designed high-voltage generator in order to improve output amplitude.For gain performance and power, reduced volume is considered economic worth and prolongs battery service life that the cancellation transformator boosts, and uses step-up coil to improve voltage specially simultaneously.This circuit adopts step-up coil L10KF361, and the elementary conduct of coil is by two audion Q1Q2/3DG6 and resistance R 11/40K, R12/40K, R13/5.The load of the oscillating circuit that 1K and capacitor C 6, C7/6800PC8/0.02 μ form.Secondary voltage multiplying rectifier filter circuit C9/2000P C10/1 μ C11/1 μ and the diode D3D4 of connecing of coil.Its high direct voltage is made voltage by the colelctor electrode that R10/100K meets amplifier tube Q3/3DA87C as 2.The interchange of amplifier tube output is drawn by C5/1 μ, and its ceiling voltage can reach more than the 100V, and under human body can the tolerance situation, this higher voltage imports in ear made the medicine ionic weight bigger, and Pulse Electric to acous stimulation more effectively.Therefore the effect that suppresses the diseased region spontaneity discharge better.This utility model has also designed a special electrode probe that can make pharmaceutical liquid importing in ear in the auditory meatus, and electrode probe is the silver chloride electrode probe.

Accompanying drawing 1 is this utility model shape assumption diagram, and Figure 1A is the external form side view, and Figure 1B is the external form vertical view.1 is wiring board, and 2 is electrode probe, and 3 is battery case, and 4 is potentiometer, and 5 are the output seat, and 6 is shell.

Fig. 2 is the layout of this utility model pulse generator.

The utility model advantage is that this instrument is that available positive voltage is made again available Pulse Electric treatment disease of medicine importing, and its curative effect height is harmless to human body. With the decline of tinnitus, hearing all has in various degree raising simultaneously. This instrument volume is little, and is in light weight, easy to carry, and long service life is safe and reliable, is a kind of device for the treatment of tinnitus and ear disease.
