Abstract
The utility model provides a miniature tinnitus therapeutic instrument which is simple, convenient, practical and advanced and is convenient for carrying and consists of a battery of 1.5 voltages, a convertor of 12 voltages, a signal generator, a frequency selector, a frequency adjuster, a low-frequency signal amplifier, a sound intensity controller and witch, a frequency indicator and a crust. The utility model is characterized by small size, light weight and being easily for carrying and in favor of the patient application to improve the treatment effect.
Description
This utility model relates to the sound stimulating method that utilizes miniature tinnitus therapeutic apparatus, to suffering from the patient of tinnitus, goes disease controlling, makes tinnitus be eased, cure down to complete obiteration with the method.
Utilization sound stimulating method treatment begins as far back as the nineties owing to the tinnitus that the disorder of audition produces.Because it is a kind of common otology clinical symptoms, the cause of disease is various, often is the simultaneous phenomenon of some disease.Though unlikely threat to life is very painful.Those whole bodies or ear there are organic disease and with the patient of tinnitus, can be by etiological treatment or operation method disease controlling, tinnitus is eased even complete obiteration.But this is the part in a large amount of tinnitus patients, can cure and quite a few patient still is in no medicine at present, can not control.Under this situation,,, all obtained satisfied effect through the participation and the clinical practice of Chinese people's militia hospital general, Beijing Tongren Hospital by the GJDS-I type tinnitus therapeutic apparatus that Chinese Medical Association, Henan Hua Kai Scientific and Technical Industry Co., Ltd develop.And by the Ministry of Public Health expert testimony, obtained certainly, think to have solved both at home and abroad for a long time to a clinical treatment tinnitus difficult problem, particularly to the tinnitus due to the multiple reason, auditory hallucination psychotic has unique curative effect.This instrument has been declared patent and has been promoted all parts of the country at present, obtains curative effect preferably, receives an acclaim.But through expert testimony think and practice need the proof, as reduced volume, weight reduction then is more convenient for the patient, its effect is better.
Task of the present utility model will solve reduced volume, weight reduction exactly, makes miniaturely, makes things convenient for the patient, simultaneously to reach the purpose that improves curative effect.
Task of the present utility model is finished as follows: utilize modern electronics and microelectric technique, the method that has adopted small-sized Resistor-Capacitor Unit, integrated circuit and transistor to combine makes volume-diminished, weight saving.Owing to adopted microelectric technique and advanced electronic circuit, can export triangular wave, square wave, sinusoidal wave three kinds of waveforms, make the volume of instrument little to being put in the coat pocket.
Below with reference to accompanying drawing utility model is described in further detail.
Fig. 1 is a circuit structure block diagram of the present utility model
Fig. 2 is the frequency indication and the shell sketch map of utility model
After energized, 1.5 volts of batteries (1) begin power supply, and 12 volts changer AH812 (2) work, conversion go out 12 volts voltages exports, for the usefulness of signal generator ICL8338 (3), while low-frequency signal amplifier (6) also electric and work.After signal generator ICL8338 (3) work, export the low frequency signal of optional triangular wave, square wave, sinusoidal wave three kinds of waveforms, through the resistance value of signal occurrence frequency selector (4) change capacitance and signal occurrence frequency actuator (5), promptly the RC time constant changes frequency frequency range and fine setting.It is five grades that frequency modulation is divided into, and frequency is 50 to 160000Hz, and is adjustable continuously.Through low-frequency signal amplifier (6), amplify the hold concurrently current potential of switch (7) of sound intensity controller and regulate sound intensity size, to reach the purpose of needs of patients.
Concrete work process: the switch (7) of at first sound intensity controller being held concurrently is opened, again the sound intensity knob is transferred to minimum, select signal occurrence frequency selector (4) Mid Frequency earlier, allow the good electroacoustic transducer of patient wear (8) (earphone) wear then into the trouble ear, the slowly light again tuning amount controller switch (7) of holding concurrently, make electroacoustic transducer (8) (earphone) sound sound be lower than patient's tinnitus sound slightly, slowly adjust fine setting frequency knob, the similarities and differences (the low-frequency range of careful simultaneously inquiry patient's acoustical signal tone and tinnitus tone, high band is adjusted the same), until stimulus frequency and tinnitus voice frequency are matched, both couplings are good more, its therapeutic effect is also more for satisfied, read concrete numerical value from frequency-indicating device this moment, charge to the patient medical record card or inform the patient, in order to the usefulness of next time treatment reference and observe the curative effect.At last volume is adjusted to and is higher than the tinnitus sound, continued stimulus 15 minutes to 30 minutes (looking the state of an illness is decided by the doctor).
The maximum characteristics of the utility model are that the patient can carry, and can be contained in the coat pocket, immediately go out Existing tinnitus can be treated at any time, improving curative effect, concrete treatment time and number of times, by the doctor according to the patient The state of an illness and deciding. Owing to selected battery No. one, can improve service time greatly in addition.
