Description
(54) УСТРОЙСТВО ДЛЯ ЭЛЕКТРООКУЛОГРАФИИ(54) DEVICE FOR ELECTROOCULOGRAPHY
Изобретение относитс к медицинской технике, а именно к устройствам дл иссле аовани биоэлектрических процессов в зрительном аппарате.The invention relates to medical technology, namely, devices for the study of bioelectric processes in a visual apparatus.
Известно устройство дл электроокулографии , содержащее последовательно соединенн1 1е электроды, усилитель, интегратор, схему выпр млени , коммутатор программного блока и регистрирующий прибор ц1A device for electrooculography is known, which comprises series-connected electrodes, an amplifier, an integrator, a rectifier, a switch for the program block, and a recording device t1.
Однако в известном устройстве исследование обменных процессов в сетчатке глаза производитс при фиксировании взора в двух положени х меток, расположенных под заданным углом, что не позвол ет адекватно судить об исследуемых процессах у еле пых или слабовид щих людей.However, in the known device, the study of metabolic processes in the retina is carried out by fixing the gaze in two positions of the marks located at a given angle, which does not allow to adequately judge the processes under investigation in people who are weak or visually impaired.
Цель изобретени - исследование обменных процессов в сетчатке глаза путем регистрации переходных процессов движени глазного блока в случа х, исключаюших точную фиксацию взора.The purpose of the invention is to study the metabolic processes in the retina of the eye by registering transient processes of movement of the eye block in cases precluding precise fixation of the eye.
Указанна цель достигаетс тем, что предлагаемое устройство снабжено последовательно соединенными дифференциатором амплитудным детектором, BTOPJ.IM коммута- This goal is achieved by the fact that the proposed device is equipped with a series-connected differentiator amplitude detector, BTOPJ.IM switch
тором программного блока, делительной цепочкой и схемой сравнени , причем вход дифференциатора включен параллельно входу интегратора, целительна цепочка соединена с регистрирующим прибором, а второй вход схемы сравнени соединен с выходом интегратора .The torus of the program block, the pitch chain and the comparison circuit, the differentiator input is connected parallel to the integrator input, the healing circuit is connected to the recording device, and the second input of the comparison circuit is connected to the integrator output.
На чертеже изображена принципиальна схема устройства дл электроокулографии.The drawing shows a schematic diagram of an apparatus for electrooculography.
Устройство содержит последовательно соединенные электроды 1, усилитель 2, схему 3 выпр млени , первый коммутатор 4 программного блока, интегратор 5, регистрирующий прибор 6, дифференциатор 7, амплитудный детектор 8, второй коммутатор 9 программного блока, делительную цепочку 10 и схему 11 сравнени . Причем вход дифферевшиатора 7 включен параллельно входу интегратора 5, делительна цепочка соединена с регистрирующим прибором 6, аThe device contains series-connected electrodes 1, amplifier 2, rectifying circuit 3, first switch 4 of the program block, integrator 5, recording device 6, differentiator 7, amplitude detector 8, second switch 9 of the program block, dividing chain 10 and comparison circuit 11. Moreover, the input of the differential switch 7 is connected in parallel with the input of the integrator 5, the dividing chain is connected to the recording device 6, and
второй вход схемы 11 сравнени соединен с выходом интегратора 5,the second input of the comparison circuit 11 is connected to the output of the integrator 5,
