Amblyopia of the present invention detection with the working mechanism of apparatus for correcting is:
What microprocessor was mainly used in realizing liquid crystal lens blocks the continuous control with transparency.Microprocessor can be sent out modulated pulse signal by its digital output port, this signal can produce the change of high and low level after being sent to the both positive and negative polarity of liquid crystal lens, driving liquid crystal lens to realize continuously adjusting the transparency of liquid crystal lens, the Heibei provincial opera being realized double vision road by the light transmittance regulating left and right liquid crystal lens respectively is saved.Additionally, microprocessor is additionally operable to realization and the communication of optical sensor, the reception of wireless command signals and process, stores calling of information；Memory card module, it is achieved the record of the information such as amblyopia rectification device wear time and training program and the storage of software；Wireless receiver, for receiving from the wireless command signals of remote controller and signal is passed to microprocessor processing；Real-time clock, in order to provide system current time, provides clock foundation for controlling covering time and record treatment time；Two optical sensors, distribution is fixed on two liquid crystal lens nasal side ends, left and right, the inner surface side that it is arranged between liquid crystal lens and eye, to measure ambient brightness after liquid crystal lens, i.e. illumination brightness received by wearer's eyes, optical sensor is connected with microcontroller by circuit, and the illumination luminance signal tested is fed back to microcontroller, to realize the closed loop regulation control of two liquid crystal lens each light transmittance；Mode selection switch, for switching different mode of operations (such as detection pattern, Therapeutic mode, training mode etc.).Whether indicator lamp, start shooting for display system, the display alarm information when battery electric quantity deficiency.
Remote controller realizes the controlled in wireless to amblyopia rectification device and function setting, the instruction of user passes through wireless signal transmission to amblyopia rectification device after remote controller inputs, on it, the instruction received is passed to microprocessor by wireless receiver, sends control signal to liquid crystal lens and realize the control of liquid crystal lens after microprocessor processes.Button microswitch on remote controller, for realizing being manually entered the light transmittance of instruction adjustable liquid crystal display eyeglass, button microswitch signal passes to single-chip microcomputer via circuit, single-chip microcomputer receives this instruction, it is sent to display module after being processed to show, and by wireless sending module, control instruction is delivered to amblyopia rectification device further, it is achieved the light transmittance regulation of liquid crystal lens.
Microprocessor can be connected with computer by data communication interface, it is achieved is transmitted more new procedures by computer to microcontroller.And then the treatment procedure in computer and training software are transmitted in the memory card module copying to amblyopia rectification device.
Amblyopia rectification device of the present invention has following 2 kinds of mode of operations:
1) detection pattern.It is mainly used in the check in amblyopia treatment initial period and therapeutic process.It is set as detection pattern by mode selection switch is optional.Microprocessor may recognize that, by the level state of detection mode selection switch, the detection pattern that is currently at after the power-up, and performs the control program under detection pattern.Set by the parameters of remote controller Non-follow control amblyopia rectification device by doctor in this mode, patient wears amblyopia rectification device, and watch the either statically or dynamically image that doctor specifies attentively, doctor changes the light transmittance of two liquid crystal lens, Part-time occlusion frequency etc. by manual control, by patient, the feedback of test image is determined the binocular vision of patient, by the light transmittance of regulation Dominant eye side liquid crystal lens, find the optimal balance point of patient's eyes, record this point in case successive treatment reference.
2) daily Therapeutic mode.It is mainly used in the daily treatment stage in amblyopia treatment mid-term.It is set as daily Therapeutic mode by mode selection switch is optional.Microprocessor be may recognize that by the level state of detection mode selection switch after the power-up and is currently at Therapeutic mode, and performs the control program under mould treatment formula.In this mode, patient is worn amblyopia treatment device by household or patient oneself in the period suitably carrying out amblyopia rectification in daily life and switches to daily Therapeutic mode, and this device will carry out the covering of liquid crystal lens according to the daily Therapeutic mode determined by doctor in advance and control.Wherein light transmittance and the covering mode of two liquid crystal lens is determined according to the testing result of patient's early stage and three-dimensional training effect by doctor, concrete daily Therapeutic mode passes through program record in storage card, under daily Therapeutic mode, arranging in microcomputer reads storage card dynamically controls light transmittance and the covering mode of liquid crystal lens.After daily treatment after a while, patient needs hospital to check, and the daily Therapeutic mode parameter in the degree amendment storage card recovered according to patient by doctor sets, and more new procedures also carries out next step treatment.
Applying amblyopia rectification device proposed by the invention, can realize following amblyopia antidote, it comprises the following steps:
Step 1: correction of refractive errors is treated.First correction of refractive errors treatment is carried out for the patient that clinical definite is amblyopia, tests and join correction of refractive errors glasses；
Step 2: amblyopia rectification device is matched.Patient through step 1 is carried out the apolegamy of amblyopia rectification device, the correction of refractive errors glasses of applying step 1 apolegamy, the amblyopia rectification device that the apolegamy present invention proposes, secures the device on correction of refractive errors glasses；
Step 3: stereopsis detects with binocular balance.The amblyopia rectification device that applying step 2 is matched, by doctor, patient is carried out stereopsis detection, doctor in a detection mode, is determined patient's stereopsis level by patient to stereopsis target feedback, and is determined patient's optimal binocular equalization point by the manually regulation of Dominant eye side liquid crystal lens light transmittance；
Step 4: daily amblyopia treatment.Patient was arranged to carry out daily amblyopia treatment after carrying out concentrating three-dimensional training.The amblyopia rectification device of patient is switched to daily Therapeutic mode, doctor is that patient determines daily therapeutic scheme according to early stage detection and the situation of concentration training, and by therapeutic scheme by program record in the storage card of amblyopia rectification device.Arrange patient to carry out paying a return visit check after specifying the daily treatment of time, repeat step 2, step 3, step 4, update therapeutic scheme according to patient's recovery situation, update the treatment procedure in storage card.If patient has been achieved for satisfied rectification effect through above step, terminate daily Therapeutic mode.
