No. 295,760 Claims priority, application Italy, July 23, 1962, Patent 672,922 8 Claims. (Cl. 128-422) The present invention relates to method and apparatus for generating pulsating waves of particular characteristics, said waves permitting treatment of the deafness caused by diseases of the middle and internal ear and which produce a total or partial lack of sensitivity of the auditory nerve.
In a modification of the invention, the apparatus is associated with a low-frequency wave generator in order to permit completing or alternating the treatment based on the aforesaid pulsating waves, by a treatment carried out by using low frequency alternating current, more particularly adapted to cure neuroses or neuritides of the auditory nerve which often accompany or cause deafness.
It is well known that until now, no means were known for the treatment of such deafness when it results from an inactivity of the sensorial receptors or of the auditory nerve. A slight gain in auditory sensitivity has been attained by the application of medical treatment on the administration of vitamin preparations. In other forms of deafness, due to alterations of the middle ear, improvements were obtained through treatments, based on tubal insufilations, with air passages and, in the specific case of otosclerosis, through surgical operations, such as those of Lempert, of Rosen, etc.
On the contrary, in the case of diseases affecting the sensorial receptors and auditory nerve, no practical result has so far been obtained by other clinical procedures, nor has anyone thought of possible cures based on physical treatments. By a number of tests I have ascertained that pulsating currrents consisting in pulse type, syecial shape radio waves have a high therapeutic activity on the sensorial receptors and nerve terminals, wherefore, by applying such currents daily for a short time, the auditory sensitivity of the patient is improved and very often even a complete recovery reached.
The apparatus according to this invention permits obtaining said particular type of current.
The accompanying drawing represents merely by way of example, an embodiment of my invention.
In the drawing:
FIG. 1 shows a block diagram of the apparatus according to my invention;
FIG. 2 shows, on a larger scale, the detail of the radiofrequency oscillator forming the main part of the apparatus;
FIG. 3 shows the form of the radio waves at the output end of the apparatus;
FIG. 4 diagrammatically shows the circuit of the apparatus when associated with a device for generating low frequency waves; and
FIG. 5 is an enlarged fragmentary cross-sectional view of one of the electrodes in place in the ear.
Referring now to FIG. 1, the apparatus comprises an audio-frequency oscillator AF OSC., which could also consist in a common microphone MIC., capable of supplying in an equivalent manner an audio frequency modulation, the two-position switch I permitting connecting to.the modulation amplifier AMP. to either said microphone MIC. or the oscillator AF OSC., the latter not being further illustrated since it is of a conventional type. The amplifier AMP. is a known type power amplifier as- 3,384,090 Patented May 21, 1968 sociated with an impedance transformer T provided for the control of the impedance (FIG. 2).
Between the modulation amplifier A P, and an oscillator RF OSC. is arranged a variable resistor Rv, which permits modifying the output of the apparatus according to the sensory characteristics of the patient.
The device RF OSC. consists of a radio frequency oscillator comprising a radio frequency thermionic oscillator TO, whose anode is fed by an audio-frequency alternating current derived from the secondary winding of the transformer T, while into the feeding circuit a radio frequency or blocking impedance Im is inserted.
Another blocking impedance 11m and a resistor Rg are inserted into the grid circuit. At C and C are indicated two feedback coupling capacitors, at CV a variable balancing capacitor, and at L and L the coils of a second radio frequency transformer. Across the circuit connected to the secondary coil L2 is inserted a variable or tuning condenser CV2 and a cathode ray oscilloscope CRO Therefore, as the anode of the apparatus RE OSC. is fed with audio frequency alternating current, at the output electrodes E a pulse type wave is formed having the forrr indicated in FIG. 3. In this wave the positive half Wave: are equal and symmetric with respect to the negative hall waves and each wave is spaced apart from the successive wave by a value not surpassing the maximum breath 01 the wave, as measured along the horizontal, while the amplitude in the vertical direction is such as to yield at output power of say the order of 50 watts.
It is obvious that any other equivalent electronic de vice capable of producing waves of the aforesaid char acteristics may identically be used for the said purpose The present apparatus operates as follows: when switcl L is placed in the position indicated in FIG. 1, the ap paratus AF OSC. drives the amplifier AMP. which. in tun feeds the apparatus RF OSC. which produces at the elec trodes E pulsating waves of the above mentioned charac teristics.
These electrodes E are applied correspondingly to th external auditory canal, as shown in FIG. 5, or to sucl parts of the head that the electric field generated encom passes the cochlea. The wave form is displayed by tllt oscilloscope CRO which is of the conventional type.
The electrodes E consist in spherical metal heads 0 approximately 814 mm. diameter and may be placed di rectly in contact with the skin surface or may be insulatet therefrom by means of an electrically insulating sheet S In the embodiment shown in FIG. 4, the aforesaid ap paratus is associated with a conventional device adapter to produce low frequency alternating currents. Said sec ond apparatus comprises a low frequency oscillator Ll OSC. connected to an amplifier AMP.
Said second apparatus is controlled manually by th' operator in response to the readings which the operato. obtains visually from a voltmeter V and a milliam mete ma. The switch I1 permits connecting the electrodes I with either apparatus.
By means of this assembly, in addition to the treat ment based on the application of pulsating radio wave and forming the subject matter of the present invention also an auxiliary or collateral treatment may be carrier out using low frequency alternating current. In order t1 perform these auxiliary treatments, the electrodes E wil be applied to appropriate areas of the head, and thu cures of neuroses and neuritides of the auditory nerv can be effected. Since such forms of neuroses and near] tides are very frequent causes of deafness, it is advan tageous to be able to have a centralized assembly avail able, which permits carrying out both treatments.
