Eyesight improving instrument to guide medicine liquid to human eye to treat eye diseases

Abstract

The eyesight improving instrument to guide medicine liquid to human eye to treat eye diseases includes a pulse generator and positive and negative electrode plates. The pulse generator includes a vibration pulse generating circuit, a vibration pulse amplifying and outputting circuit, and a timing control circuit. The vibration pulse generating circuit includes two pulse vibrators, each of which comprises a voltage compressor and resistors, capacitors and other electronic elements; and one third voltage comparator, which accepts two square wave signals of frequency of 3500-4500 Hz and 35-100 Hz separately from the two pulse vibrators to generate harmonics of 35-4500 Hz frequency. The harmonics is then amplified in the vibration pulse amplifying and outputting circuit to 100-1000 mV amplitude, and the amplified harmonics are coupled to the electrode plates. The timing control circuit controls the operation time of the vibration pulse generating circuit.

Description

technical field [0001] The utility model relates to a vision intensifying instrument for introducing medicinal liquid for treating ophthalmic visual impairment into human eyes, which comprises a pulse generator and a pair of positive and negative electrodes. Background technique [0002] Eye vision is very important to human health. However, with the improvement of the social environment and the prolongation of people's life expectancy, the incidence of senile cataract is increasing day by day. In addition, glaucoma and optic atrophy are also common eye diseases in the elderly. At present, the treatment of senile cataract at home and abroad mainly relies on surgery to restore sight after maturity, but for eye diseases such as immature senile cataract, glaucoma and optic atrophy, no effective treatment method has been found to prevent the development of the disease. [0003] In addition, at present, the target therapy of forced amblyopia eye fixation treatment for children w...

AI Technical Summary

Problems solved by technology

At present, the treatment of senile cataract at home and abroad mainly relies on surgery to restore vision after maturity, but for eye diseases such as immature senile cataract, glaucoma and optic atrophy, no effective treatment method has been found to prevent the development of the disease.

[0003] In addition, at present, the target therapy of forced amblyopia eye fixation treatment for children with amblyopia at home and abroad has the disadvantages of slow curative effect, long course of treatment (the average cure time is about 2.5 years), and low cure rate (the average cure rate of severe amblyopia is only 16.88%). Problem, in the 1990s foreign countries began to use drug treatment, but only 44% of them maintained the curative effect after stopping the drug, and the drug has side effects, so it cannot be used for a long time
