HARDWARE-SOFTWARE COMPLEX FOR HEARING RECOVERY
"CHAKRA-3H COMPUTER NEUROSTIMULATOR"


3h-web-1


The complex is destined for the treatment of hearing disturbances by means of transcutaneous electric stimulation of the acoustic nerve.


INDICATIONS FOR APPLICATION


Sensorineural deafness caused by:

  • pregnancy and childbirth pathologies leading to the child hypoxia or brain trauma (toxicoses, abortion threat, various gynecopathies during the pregnancy, birth traumata);
  • neuroinfections (meningitis, meningoencephalitises, influenza, etc.) and other infectious diseases;
  • application of ototoxic antibiotics (streptomycin, hentamicin, monomicin, kanamycin, etc.) and other drugs during various diseases treatment (narcotics, trichopol, etc.);
  • craniocerebral trauma or barotrauma;
  • brain vessels disorders (hypertension, cerebral atherosclerosis);
  • hereditary factors;
  • professional injurious effects (industrial noise and others).

A treatment course is carried out continuously for 10 - 15 days, with 10…30 minutes a day.

Considerable improvement of hearing can be observed not only during the treatment course, but in 3…4 months later also. Further improvements can be achieved by repeating the treatment courses in 5…6 months.


BASIC SPECIFICATIONS

  • Multichannel automatic transcutaneous stimulation by means of a multizone ear electrode.
  • Type of electric stimulus: periodic sequence of bipolar rectangular current pulses with controllable amplitude, frequency, and duration. The pulses are grouped into packets, series, and cycles.  
  • Ability for automatic frequency variation during the stimulation by periodic or random law (frequency swinging).
  • Mapping a diagram of actual stimulus parameters (current and voltage values) for each stimulated zone.
  • Complex body impedance measuring for each stimulated zone both in stimulus intensity setting and stimulation modes.
  • Mapping the dynamics of actual complex body impedance for each stimulated zone.
  • Use of preset (typical) stimulus parameters values or manual setting the desirable values.
  • The hardware module is powered by the computer accumulator.
