Hauv kev kuaj mob neurophysiological niaj hnub thiab kev tshawb fawb, qhov tseeb ntawm electroencephalography (EEG) kev kuaj xyuas tsis yog nyob ntawm qhov ua tau zoo ntawm lub tshuab hluav taws xob thiab cov kaw lus kaw, tab sis kuj nyob ntawm qhov zoo ntawm cov teeb liab tau txais pem hauv ntej kawg. EEG comb electrode lub cev, ua tus choj tseem ceeb txuas tus neeg mob cov tawv taub hau electrodes rau EEG tshuab, ncaj qha cuam tshuam rau kev ncaj ncees ntawm EEG teeb liab thiab kev ntseeg siab ntawm kev kuaj pom los ntawm nws cov qauv tsim, kev tsim khoom, thiab kev ntseeg tau. Rau EEG cov khoom lag luam wholesale, cov chaw muag khoom kho mob, thiab cov chaw yuav khoom ntawm cov tsev kho mob loj, xaiv lub siab - zoo EEG zuag hluav taws xob lub cev txhais tau tias muab qhov kawg- cov neeg siv nrog kev ruaj khov, ua tau zoo, thiab tus nqi- cov teeb liab kis tau zoo.
Ib qho EEG comb electrode pob tw tsis yog ib qho kev sau ntawm cov xov hlau. Nws yog ib qho kev tsim qauv zoo tsim los xa cov cim tsis muaj zog bioelectrical (feem ntau nyob rau theem microvolt) tau los ntawm kaum lossis ntau pua ntawm cov tawv taub hau electrodes rau cov cuab yeej kaw tsis muaj kev cuam tshuam thiab tsis muaj suab nrov. Ib qhov zoo- tsim EEG comb electrode lub cev muaj peev xwm daws tau cov teeb meem tshwm sim hauv chaw kho mob, xws li kev cuam tshuam hluav taws xob, kev ntxhov siab, kev ntxig thiab tshem tawm, thiab cov txheej txheem ua kom tsis muaj menyuam txhua hnub.
Rau cov neeg lag luam wholesale, ntsuas EEG comb electrode trunks feem ntau tsom rau ntau qhov loj me: cov teeb liab kev sib raug zoo thiab kev ruaj ntseg, lub cev muaj zog, kev siv yooj yim ntawm kev kho mob thiab kev ua haujlwm, thiab tag nrho cov nqi ntawm cov tswv cuab nyob rau lub sij hawm ntev. Peb yuav txheeb xyuas txhua yam ntawm cov no kom ntxaws qhia seb tus kws tshaj lij li cas -qib EEG comb electrode trunk tsim nws cov txiaj ntsig kev sib tw hauv cov cheeb tsam no.
Kev Ncaj Ncees: Kev Tiv Thaiv "Qhov Tseeb" ntawm EEG los ntawm Qhov Chaw
EEG cov teeb liab yog qhov tsis muaj zog thiab ua rau muaj kev kis kab mob los ntawm ib puag ncig hluav taws xob hluav taws xob (xws li 50/60Hz lub ntsiab cuam tshuam thiab hluav taws xob los ntawm lwm yam khoom siv kho mob). High- zoo EEG comb electrode trunks siv ob lossis ntau yam ntaub thaiv npog. Lub puab txheej ntawm nruj nreem woven tooj liab mesh, ua ke nrog cov txheej txheej ntawm tag nrho cov aluminium foil shielding, tsim ib tug zoo Faraday tawb, thaiv sab nraud electromagnetic cuam tshuam rau qhov loj tshaj plaws. Ib txhij, cov txheej txheem twisting ntawm txhua lub xov hlau sab hauv yuav pab tshem tawm ntau yam - hom kev cuam tshuam, kom ntseeg tau qhov purity ntawm cov teeb liab sib txawv (xws li, qhov sib txawv ntawm ob lub electrodes). Tag nrho cov txhuas txhuas yog ua los ntawm siab -purity oxygen- tooj liab dawb thiab ua ke nrog cov ntaub ntawv tshwj xeeb insulating kom ruaj khov thiab qis inter{12}} kab capacitance, uas yog ib qho tseem ceeb rau kev sib kis ntawm high{13}} zaus EEG Cheebtsam (xws li gamma nthwv dej). Qhov kev mob siab rau ntawm lub teeb liab kev ncaj ncees no ua kom ntseeg tau tias cov ntaub ntawv morphology, amplitude, thiab cov ntaub ntawv theem ntawm EEG teeb liab tau ua ncaj ncees rau txhua txoj hauv kev los ntawm tus neeg mob lub taub hau mus rau cov cuab yeej kaw.
Rugged thiab Durable: Nrog rau qhov kev sim hnyav ntawm siab -Kev siv tshuaj kho ntau zaus
Ib puag ncig ntawm tsev kho mob EEG chav lossis cov tsev kho mob hauv lub paj hlwb xav tau tshwj xeeb ua haujlwm ntev los ntawm cov khoom. Tus qauv tsim ntawm EEG comb electrode trunk kab yuav tsum tiv taus ntau yam tangling txhua hnub, rub, ntxig / tshem tawm, thiab ua kom tsis muaj menyuam. Cov ntsiab lus tseem ceeb ntawm kev txhawb nqa muaj xws li:
Lub cev lub cev thiab cov ntsiab lus bifurcation: Cov cheeb tsam no yog cov cheeb tsam ntawm cov neeg kho tshuab kev nyuaj siab. Ib qho elasticity heev, qaug zog-kev kho mob tiv taus- qib PVC lossis TPU txheej txheej, ua ke nrog cov fibers sab hauv, zoo tiv thaiv rov qab khoov. Cov ntsiab lus bifurcation siv ib qho -thov txhaj tshuaj-moulded stress-buffered qauv los tiv thaiv cov xov hlau sab hauv vim kev khoov ntev.
Electrode kev sib txuas cov ntsiab lus: Kev sib txuas rau kub -plated koob electrode los yog khob- zoo li tus electrode siv cov txheej txheem siab -precision crimping, kaw nrog kev kho mob- qib silicone thiab tiv thaiv los ntawm lub plhaub. Qhov no ua kom muaj kev sib txuas hluav taws xob ruaj khov thiab txhim khu kev qha thiab tiv thaiv cov dej nkag thaum lub sijhawm ntxuav thiab tua kab mob.
Khoom siv interface: Lub ntsaws siv lub siab - lub zog engineering yas plhaub, nrog tuab kub plating ntawm cov hlau sab hauv. Qhov no tsis tsuas yog guarantees zoo heev conductivity thiab oxidation tsis kam, tab sis kuj withstands kaum tawm txhiab ntawm insertion thiab tshem tawm mus, deb tshaj qhov yuav tsum tau ntawm niaj hnub kho mob siv. Clear xim coding thiab cov lej cim kom ceev thiab raug kev sib txuas txawm nyob rau hauv ib puag ncig tsis khoom.
Clinical efficiency thiab cov neeg siv kev paub: Optimized workflow.
Lub sij hawm yog efficiency. Tus kws tshaj lij EEG comb electrode lub cev txhim kho kev khiav hauj lwm nrawm los ntawm cov neeg siv - tus qauv tsim tus phooj ywg. Cov txheej txheem xim thiab tus lej (feem ntau ua raws li thoob ntiaj teb 10-20 qhov system lossis nws qhov txuas ntxiv) ua rau cov kws tshaj lij txhawm rau txheeb xyuas thiab txheeb xyuas txhua qhov electrode channel. Cov kab hluav taws xob hloov tau yooj yim thiab tsim qhov ntev tsim tau yooj yim rau kev tso chaw rau cov neeg mob thiab kev tswj xyuas yooj yim los ntawm cov kws tshaj lij, txo cov tangling. Lub teeb yuag yuav txo tau lub taub hau, ua rau nws tshwj xeeb tshaj yog haum rau ntev -lub sij hawm yees duab EEG xyuas. Tsis tas li ntawd, tag nrho cov qauv tsim txhawb kev tu thiab tshuaj tua kab mob kom zoo (xws li kev sib raug zoo nrog cov ntshav plasma lossis cov tshuaj tua kab mob tshwj xeeb), ua kom muaj kev tiv thaiv kab mob thaum ua kom muaj kev hloov pauv sai.
Hauv kev xaus, EEG zuag hluav taws xob lub cev yog ib qho tseem ceeb tshaj plaws hauv kev kuaj EEG. Nws tus nqi yog nyob rau hauv kev nkag siab tob txog cov teeb liab kev tshawb fawb, kev nkag siab meej ntawm cov kev xav tau ntawm kev kho mob, thiab kev tswj xyuas nruj ntawm cov txheej txheem tsim khoom. Peb tau cog lus los muab cov khoom tsim kho thiab txhim khu kev qha rau kev kuaj mob neuroscience thoob ntiaj teb thiab kev tshawb fawb los ntawm kev txuas ntxiv thev naus laus zis tshiab thiab kev ua haujlwm zoo.
