Abstract

The utility model which is used to detect the cerebral function discloses an assaying instrument for the reaction time of the cerebrum. The visual and acoustic organs of the subject are respectively stimulated via four different color photo-signals at the back side of the instrument and acoustical signals coming out from four azimuths according to a certain procedure; the limbs of the subject respectively and flexibly control the completion key used to complete the instruction action; A digital display timer on the right side of the instrument accurately record the time from the emission of each signal to the exact completion of the instruction action. The utility model which can carry out the quantitative evaluation to the cerebral function can be used to diagnose, treat the brain function detriments such as the cerebral arteriosclerosis and the senile dementia and judge the cure effect in the clinical medicine; at the same time, the utility model can also act as the objective reference index of the departments of the traffic, the physical culture and the troop to single out the talent with special skills.

Description

Assaying instrument for reaction time of cerebrum

The invention belongs to a kind of medical diagnosis instrument, be mainly used in mensuration the human brain response time.

The functional system of brain is the functional activity of a kind of complexity of being finished by some part synergism of brain, after being reacted to brain by look, audition etc., make the corresponding instruction sexual act by brain, testing out brain stimulates the speed and the accuracy of the combined reaction of doing to external world, thereby the function of judging brain promptly is a purpose of the present invention.At present, the general employing read multiple IQ card, confirms the function of its brain thus.The inventor also once met two groups of light of a kind of usefulness and hand push button comes the report of the selective response of test subject, but because the mode of test is single, can not react the integrated function of brain.

The present invention has designed a kind of existing sound and optic signal, detects the instrument of brain response speed again by human limb.

The present invention is achieved in that the circuit that will form this instrument is installed in the housing (1), has on and off switch (2), power supply indicator (3), timing to show (4), four command signal control keys (5), registration card (6), command signal display lamp (7) and acousto-optic selector switch (8) on the front panel of housing (1); Command signal lamp (9), command signal sound source (10) are arranged on the reverse side panel of housing (1), lead (11), lead (12) are arranged simultaneously, be connected with two respectively and manually finish key (13) and two foot-operated keys (14) of finishing; In the side of housing (1) an external sound source socket (15) is arranged.Circuit part of the present invention has: power circuit (16), sprocket pulse circuit (17), digital control display circuit (18) and instruction, reaction control circuit (19), sound light control circuit (20) and reset key AN ₁Control key AN ₂, AN ₃, AN ₄, AN ₅The back meets NAND gate IC ₂Input, NAND gate IC ₂Outfan one tunnel meet NAND gate IC ₁Input, another road then meets four groups of multiple tube BG ₃-BG ₄, BG ₅-BG ₆, BG ₇-BG ₈, BG ₉-BG ₁₀, the colelctor electrode of these four groups of multiple tubes then connects signal lights and light emitting diode and speaker y ₁～y ₃On, finish key AN ₆, AN ₇, AN ₈, AN ₉Then control phase inverter F respectively ₅～F ₈Input, the outfan of phase inverter then inserts NAND gate IC ₃, IC ₄Input, NAND gate IC ₃, IC ₄Outfan insert NAND gate IC ₂Another road input, NAND gate IC ₁Outfan be connected to timer.

Connection by foregoing circuit and installation, the fixing brain response time detector of promptly making.

Accompanying drawing 1 is a shape assumption diagram of the present invention, and accompanying drawing 2 is structured flowcharts of the present invention, and accompanying drawing 3 is circuit theory diagrams of the present invention.

In the circuit theory diagrams of accompanying drawing 3, control key AN ₂～AN ₅Be operator's control, promptly command signal control key (5) is operator's control; Finish key AN ₆～AN ₉Be testee control, promptly manually finish key (13) and the foot-operated key (14) of finishing is that testee is controlled; Work as AN ₂～AN ₅In any one press then corresponding NAND gate IC ₂Outfan is a low level, corresponding phase inverter F _1～4Outfan is a high level, and through the current limliting of resistance, at this moment corresponding multiple tube conducting can utilize acousto-optic selector switch (8), i.e. K ₁To acousto-optic select to make command signal display lamp (7), command signal lamp (9) is luminous or make command signal sound source (10), i.e. y ₁～y ₈Sounding; Meanwhile, IC ₁Connect, and pass the signal along in the timing circuit, make timing show (4) work, timing.Accurately press when testee and to finish key AN accordingly ₆～AN ₉The time, make corresponding phase inverter F _5～8Input high level, NAND gate IC ₃, IC ₄Be output as low level, then IC ₂Close, multiple tube ends, thereby makes corresponding light extinguish or stop sounding.Timer also stops timing; Timing shows that (4) go up the time that shows just is a test data like this, it can be recorded on the registration card (6), uses reset key AN then ₁Zero clearing can begin to have tested so again once more.For the ease of some test in particular cases, be provided with external sound source socket (15) at this instrument, can the distant control test.

The present invention can adopt the bridge circuit rectification, makes AN with nine key switches open in usual ₁～AN ₉Timing shows uses LED ₁～LED ₄Molectron is formed, and command signal display lamp (7) is made of colored lights ZD of light emitting diode making, command signal lamp (9).

The present invention is by the optical signal of four kinds of different colours of instrument and the acoustical signal in four orientation, stimulate the looking of experimenter, listen organ according to certain program, four limbs by the experimenter are controlled the key work of finishing flexibly, the speed of experimenter's brain response accurately can be recorded, it can make quantitative evaluation to cerebral function, helps to provide the diagnosis of clinical medicine to patient's brain diseases and the objective quantitative target of curative effect judgement; A kind of testing tool of novel, science also can be provided when selecting the special talent for departments such as traffic, physical culture, armies simultaneously.
