Abstract
This utility model relates to the cognition of a kind of brain and mental status checkout gear, be provided with acquiring brain waves sensor, brain wave collector, host computer, printer successively, described acquiring brain waves sensor adopts two crosslinking electrode connected mode, collection be the brain wave of frontal lobe.Adopt dry-type electrode, electrode adopts corrosion-resistant, resistance to oxidation and the fabulous alloy electrode of electric conductivity.Place between the eyebrows central electrode is zero potential electrode, respectively arranges the acquiring brain waves electrode that is detected left and right brain hemisphere above the eyebrow of left and right.This utility model, by gathering brain wave, and to brain wave patterns in addition analyzing and processing, then compares alternately the parameter of different crowd, thus analyzes brain wave feature corresponding to different people, find out its large brain cognitive function state and mental status value.
Description
Technical field
This utility model belongs to the test and assessment device of a kind of brain cognitive function and mental status, be the directly perceived effective new method for psychological assessment in brain electricity science, neuroscience and science of psychology field, it establishes contacting between the brain cognition of brain wave patterns and people and psychological health states effectively.
Background technology
The mankind, in the process of carrying out vital movement, can produce various bioelectrical signals (as: electrocardio, myoelectricity, brain electricity) and non-electrical biological signals (as: blood pressure, tension force, breathing) etc.These signals of effective seizure, can understand the meaning of the vital movement of representative conversely.
The mankind are the higher mammals with high-level thinking ability.He know of normal people, feelings, meaning, row are almost all by the control of human thinking activity.But the thinking activities process of brain is very complicated.Thus brain science research is referred to as last fort natural science applied.The scientists of countries in the world has all carried out a large amount of intensive research to the brain wave produced during human thinking in recent decades.At medical domain, by measuring various Biological indicators, particularly brain electricity index, the lesion type and the diseased region that disclose patient are very general.And cognitive function and the mental status of brain is evaluated as the difference by brain wave, also fewer comparatively speaking.
Utility model content
The purpose of this utility model is to solve. the problems referred to above, the cognition of a kind of brain and mental status checkout gear are proposed, this brain cognition and mental status checkout gear are by gathering brain wave, and to brain wave patterns analyzing and processing in addition, again the parameter of different crowd is compared alternately, thus analyze brain wave feature corresponding to different people, find out its large brain cognitive function state and mental status value.
The purpose of this utility model is achieved through the following technical solutions: brain cognition and mental status checkout gear, it is characterized in that: be provided with acquiring brain waves sensor, brain wave collector, host computer, printer successively, described acquiring brain waves sensor adopts two crosslinking electrode connected mode, collection be the brain wave of frontal lobe.Adopt dry-type electrode, electrode adopts corrosion-resistant, resistance to oxidation and the fabulous alloy electrode of electric conductivity.Place between the eyebrows central electrode is zero potential electrode, and respectively arrange the acquiring brain waves electrode that is detected left and right brain hemisphere above the eyebrow of left and right, left and right ear arranges a reference electrode respectively to eliminate the interference of electromyographic signal to eeg signal; Described brain wave collector accepts the instruction of host computer, for the treatment of the eeg signal gathered in good time, by amplifying, removing the method such as spurious signal, elimination distortion, eeg signal is processed, and by A/D converter, analogue signal is converted to digital signal, by RS232 communications protocol, test data is transferred to host computer; Described host computer is provided with the instruction repertorie controlling brain wave acquisition device and start to gather eeg signal and stop gathering, the program data show, record, stored, and having the statistical function of data automatically being compared, analyzing, host computer also line command printer will detect the function of comparison result printout.
The system of a set of acquiring brain waves of the present utility model and analysis, when people is under different physical and mental statuses, cerebral activity produces the brain wave patterns of different characteristic.By brain wave patterns nurse one's health, amplify, and and then to signal carry out mould/number (A/D) change, make it to enter host computer.Software mainly completes and to control system components and bio signal to digitized shows, records, stores, processes and printout.Collect the brain wave patterns of a large amount of different crowd, in conjunction with their virtual condition and performance, analyse and compare, the norm value that just can draw characteristic parameter and correspond.Different Individual compares the index that can analyze each individuality with norm good and bad.
During use, first acquiring brain waves sensor acquisition eeg signal, sends brain wave collector to, carries out the conditioning of Na electric wave signal, amplification, and and then to signal carry out mould/number (A/D) conversion, send data to host computer by RS232 communications protocol.Host computer by software system, mainly completes to control system components and bio signal to digitized shows, records, stores, processes and printout.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further described:
Embodiment: see accompanying drawing 1, brain cognition and mental status checkout gear, be provided with acquiring brain waves sensor 3, brain wave collector 2, host computer 1, printer 4 successively, described acquiring brain waves sensor adopts two crosslinking electrode connected mode, collection be the brain wave of frontal lobe.Adopt dry-type electrode, electrode adopt that resistance to brain loses, resistance to oxidation and the fabulous alloy electrode of electric conductivity.Place between the eyebrows central electrode is zero potential electrode, and respectively arrange the acquiring brain waves electrode that is detected left and right brain hemisphere above the eyebrow of left and right, left and right ear arranges a reference electrode respectively to eliminate the interference of electromyographic signal to eeg signal; Described brain wave collector accepts the instruction of host computer, for the treatment of the eeg signal gathered in good time, by amplifying, removing the method such as spurious signal, elimination distortion, eeg signal is processed, and by A/D converter, analogue signal is converted to digital signal, by RS232 communications protocol, test data is transferred to host computer; Described host computer is provided with the instruction repertorie controlling brain wave acquisition device and start to gather eeg signal and stop gathering, the program data show, record, stored, and having the statistical function of data automatically being compared, analyzing, host computer also has order printer to detect the function of comparison result printout.
Last it is noted that obviously, above-described embodiment is only for this utility model example is clearly described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of extending out or variation be still among protection domain of the present utility model.
