Photostimulator for electrophysiological examinations
专利摘要:
An electrophysiological photostimulator, particularly to study evoked visual potentials, comprises a luminescent matrix source, its surface having unit sources arranged in order under a control unit. The control photostimulator in the control unit has function, shape and form programmers, which control the stimulation source that is the luminescence matrix through an adder with a steady luminance level unit and a system for switching over the y and y lines and lighting up systems. The shape and form programmers solve the problem of dynamic stimuli understood as successive alternations of shape during one stimulus T. The described photostimulator facilitates the examinations in the field of electroencephalography, electroretinography, electronstagmography and electroocculography. Owing to the application of the other kinds of stimuli instead of the light ones the described photostimulator can successively be used in an other branches of electrophysiology, where a collective stimulation of the respective physiological organs is necessary. 公开号:SU1039435A3 申请号:SU792786607 申请日:1979-07-10 公开日:1983-08-30 发明作者:Хэнрык Сяркевич Петр;Вацлав Захарски Богдан 申请人:Институт Псыхонэурольогичны (Инопредприятие); IPC主号:
专利说明:
The invention relates to medical instrumentation, in particular, to a photototumpe mount for eectrophysiological and environmental testing, and can be used with automatic systems for the analysis of eectrophysiological signals. A well-known photostimulator for electrophysiological studies, containing a source of stimulation and a control unit lj. However, the known stimulator does not provide a dynamic light pulse of variable spatial constant luminance. The purpose of the invention is to obtain more accurate results in the study of Baftittix's visual potentials of the brain, complicated by severe neurological diseases. The goal is achieved by the fact that in a photo-stimulator for electrophysiological studies containing a source of stimulation and a control unit, the source of stimulation is performed in a luminescent matrix with luminous elements placed on it sequentially connected to ignition systems, and the control unit contains an adder, a programmer functions, with the programmers of the type and form taken between each other and the manipulation system with two outputs, one of the outputs of which is connected to the CELLULAR elements and the ignition systems These are connected with the second output of the manipulation system and the adder, the latter being connected to the programmer of the function, and the programmer of the type is connected to the manipulation system. Fig, 1 shows a block diagram of the photos: 5tor; , 2 - view of the matrix. with light idimas elements at time P; in fig. 3 - the same, at time P + 1; in fig. 4 shows the time variation of the signals controlling the individual blocks. A photostimulator consists of a control unit including a constant level change system 1, a programmer of 2 functions, a generator of 3 intervals, a programmer of 4 types, a programmer of 5 forms, an adder b and a system of 7 manipulations with two outputs. as well as systems of 8-11 ignition and luminous elements 12-27. One of the outputs of the manipulation system 7 is connected to the luminous elements 12-27, ignition systems 8-11 are connected with the second control system 7 of the manipulation and sum ... the device 6, the latter being connected to the programmer 2 of the function and the system 1 changing the constant level, and the programmer 4 of the type is connected to the manipulation system 7. In addition, the programmer 5 of the form is associated with a programmer of 4 types, a generator of 3 time intervals and a programmer of 2 functions, and the generator of 3 time intervals is associated with a programmer of 4 types. Photo Stimulator I works as follows. The generator 3 time intervals works as a clock generator with a period of G, which has two outputs, where the signal frequency of one output is a multiple of (K) to the frequency of the other output. The programmer 2 of the function generates a single impulse of a given function, for example, trapezoidal with programmable parameters (duration, rise time and soldering of the fronts after each apparent impulse from generator 3 with periope T). The impulse-given function is summed in adder 6 with the value of the component, which is a constant change from the system 1 of the change in constant level. In sum, the signal passes into the ignition systems of §-11, igniting the light elements 12-27 of the matrix. The programmer 5 of the form, released by the pulse of the generator 3, emits to the programmer 4 of the signal about transferring this type to the luminescent matrix of the luminous elements 12-27 after each period of the pulse T. The programmer 4 vdda emits into the 7 manipulation system a signal that manipulates the X and Y lines, which causes the transmission of pulses along the X lines to the systems 8-11, which ignite the luminous elements, and on the Y lines. FIG. 2 and 3 illustrate the reversibility of the luminous luminescent elements for static pulses. To obtain a dynic impulse, it is necessary to programmer 4 types of excitement with the appropriate number of pulses P of the generator 3 time spans, frequency K times more than 1 / T pulses that suspend the programmer 2 functions and programmer 5 forms. Then the change of ida on the luminescent matrix will occur at intervals of K times or more than the period of the pulse T, in order for the dynamic pulses to be once 3 0394354 Tchaemye, it is necessary to satisfy the inequaline retinography, electronistagmus raffia, which provides more than , jg K ptochnyh results in the study of imaged visual potentials of the brain, The invention makes it possible to alleviate the complicated neurological advanced in the field of electroencephalography, diseases. // pshtezh T.zffT.T.T.2j L T: .T. l.fs Ji eight and uz.l About About About About About ° 0 ° 0 ° 0 ° 0 ° ° ° ° ° 0 ° 0 ° ° ° ° ° 0 ° 0 ° Ж ° 0 ° 0 ° Ж ° 0 ° 0 ° ig.2. oh oh oh oh oh oh oh oh oh oh oh oh ° Ж ° 0 ° 0 ° ° 0 ° 0 ° 0 ° 0 ° 0 ° w ° w Fig.Z 6
