Abstract

The utility model discloses an electrotherapeutic instrument for pseudo myopia, comprising a pulsed triggering circuit, a pulsed oscillation device, a display device, an amplifier, a clipping circuit, an amplitude control component, a frequency control component, a direct current power supply, and an output electrode. Pulsed square wave with certain frequency, scope, and width can be output, and the frequency is consistent with the bioelectric current frequency of the human body. The output pulse is added between the back side of the shank of the human body and the both eyes, so that the eye region can generate flutter and the brain can generate sleepiness to improve the microcirculation of the eye region, eliminate the fatigue and spasm of the ciliary muscle, and relieve the excitement and stress of the brain; the adjusting function of the eye region is gradually restored, the purposes of treating eye and quieting spirit are achieved, and good effects are received through the clinical applications.

Description

Electrotherapeutic instrument for pseudomyopia

This utility model relates to a kind of pseudomyopia electronics control instrument, belongs to ophthalmology physiotherapeutic instruments technical field.

Pseudomyopia is meant the adventitious myopia day after tomorrow, claims student's property myopia again, and is quite general in teenager, and sickness rate is up to more than 60% of students, and has the trend that increases year by year, this problem to cause the concern and the attention of various circles of society.

In the prior art there be the pseudomyopia Therapeutic Method: dripping eyedrop, and the massage eye, acupuncture is worn glasses, operation etc., treatment mechanism there is no and elaborates, and curative effect is also undesirable, be unable to undergo the test of time, even side effect is big, the patient is difficult gives acceptance, can't penetration and promotion.The patent No. 87207490 A61F 9/00 therapeutic instrument for shortsightedness is with simulation of optical systems visual field environment, intra-ocular lens, ciliary muscle are enhanced and recover; The patent No. 87210479 myopia speed treat device be the action of a magnetic field with high magnetic flux density on eyelash flesh to reach therapeutic purposes; The patent No. 862052785 myopia machines are to treat with the method for mechanical shock massage Jingming acupoint.In a word, the treatment mechanism imperfection of these instrument and equipments, cogency is not strong, lacks enough clinical statistics data.

The purpose of this utility model is, a kind of basis pseudomyopia electronics that new treatment mechanism is manufactured control instrument is provided, it adopts low frequency pulse current to improve the eye microcirculation and eliminates fatigue of ciliary muscle and contracture, simultaneously can further recover the regulatory function of brain again to optic nerve, thereby receive and control eye, calm the nerves, treat soon, the effect that curative effect is high.This instrument is small and exquisite, is convenient to household person and uses.

This utility model is achieved in that Fig. 1 is the principle block chart, and pseudomyopia electronics control instrument is shaken by pulsed triggering circuit, pulse Device, display, pulse amplifier, clipping circuit, spoke degree controller, frequency controller, dc source, output electrode are formed.Figure two is a schematic circuit, produces triggering signal with RC circuit repeated charge, and from the input of 555 time-base integrated circuits, 2 feet, generation is shaken , from the 3rd foot output square wave, the maximum output current of 3 feet is 200mA, in order to the speed of driven for emitting lights diode display frequency.Shake

Signal amplifies by the base stage that Resistor-Capacitor Unit is coupled to low noise power tube 9013, and transformator boosts, and diode 1N4007 carries out slicing, treats to human body by the suitable pulse of electric resistance partial pressure output.Instrument power source uses 9 volts of aneroid battery.The frequency of output pulse is 3～12HZ, and pulse width 0.3～0.5ms, spoke degree are 0～120V, and the output electrode positive pole connects the human body posterior leg, and negative pole is close to the exterior angle of eyes, makes it hide 1/2 above palpebral fissure.For guaranteeing good convenient use of conduction, electrode is wrapped up in lining cloth with lead flake and is made.

Treatment principle of the present utility model is such, and the pathogenic factor more complicated of pseudomyopia has direct important relationship with long-term near-distance reading.Students ' reading textbook, data, to do the exercises be complicated vision and mental activity.Long-term continue closely to read singly to cause eyes ciliary muscle anxiety, fatigue easily, so the ciliary muscle contracture, and crystal becomes the protruding eye variation that waits, and also easily causes the regulatory function " malfunctioning " of brain and visual organ.In other words, continue closely to read not only " labor " eye, also " trouble " simultaneously.So when the treatment pseudomyopia, not only will control eye, also must calm the nerves simultaneously, adjust cerebral neural function.With this instrument treatment pseudomyopia, taken into account the effect of above-mentioned two aspects, this is maximum characteristics and the superiority of this instrument on Therapeutic Method.Until now, domestic also nobody is familiar with like this and put into practice.

This instrument is exported the low-frequency pulse square wave of certain spoke degree and width, and this frequency is consistent with the bioelectric current frequency of human body.When pulse current passes through eye; can make eye produce significantly vibration; not only to improving eye circulation and metabolism; eliminate and alleviate the pointed therapeutical effect of the tired spasm of ciliary muscle, and after pulse current influences brain by eye, make patient's whole body comfortable; produce serious sleepiness; according to " sleep " is that brain " shutdown self check " carries out the theory of selfrepair, so can alleviate excitement, the anxiety of brain, progressively recovers the regulative mechanism to eye.The brain headquarter of for a long time closely reading to overwork is had certain regulating action, control eye and calm the nerves, prevent and treat the purpose of pseudomyopia thereby reach.Any untoward reaction and side effect are not seen in the research, test, the clinical practice that come 5 years more.There is the half patient can go into the sleep state very soon in the treatment.

This instrument volume is small and exquisite, and is easy to use, and low price is suitable for the household person oneself and treats.Good during use for guaranteeing the output electrode conduction, need that electrode is put into warm water earlier and soak into, do not drip with lining cloth and be advisable in the taking-up back.During treatment 1～2 time/day, 20～30 minutes/time, 15～30 times was a course of treatment, finished the back course of treatment and had a rest 7～10 days, can continue next course of treatment.
