Ua ntawv thov EEG elctrodes kom zoo yog qhov tseem ceeb kom tau txais cov txiaj ntsig zoo, muaj tseeb ntawm lub hlwb ua haujlwm. Ntawm no yog cov lus qhia ib qib zuj zus ntawm kev yuav ua li cas thov Eeg cov electrodes siv cov qauv {}} system:
1. Npaj tus neeg mob
Piav qhia cov txheej txheem: Nco ntsoov tias tus neeg mob nkag siab txog dab tsi yuav tshwm sim, lub hom phiaj ntawm kev sim, thiab nws tsis muaj qhov tsis pom zoo thiab tsis mob.
Ntxuav cov tawv taub hau: Siv cov cawv haus cawv lossis tawv nqaij npaj ua kom huv si rau saum tawv taub hau qhov hluav taws xob yuav muab tso rau. Qhov no tshem tawm cov roj thiab cov tawv nqaij tuag los txhim kho kev sib cuag hauv elottrode thiab txo cov impedance.
2. Ntsuas thiab Mark Electrode qhov chaw (10-20 system)
Txheeb xyuas cov kab ntawv tseem ceeb: Nrhiav qhov tshuaj xyuas (choj ntawm lub qhov ntswg) thiab cov inion (qhov tseem ceeb tshaj plaws tom qab lub pob txha taub hau). Cov no yog cov ntsiab lus tseem ceeb siv rau ntsuas cov haujlwm electrode.
Ntsuas cov taub hau ncig: Siv daim kab xev ntsuas kom ntsuas qhov kev ncua deb ntawm qhov chaw nyob nruab nrab thiab insion, thiab los ntawm pob ntseg rau pob ntseg, tshaj sab saum toj ntawm lub taub hau.
Mark Cov chaw nyob: Raws li {10-20 System, cim lub hau ntawm 10% thiab 20% sib nrug raws lub taub hau ib ncig ntawm lub taub hau thiab nruab nrab. Cov chaw hauv cov hluav taws xob suav nrog FP1, FP2, F4, C3, P3, P3, P3, P3, OTC, thiab lwm yam (saib cov duab kos rau qhov chaw muaj tseeb).
3. Thov siv cov gel lossis muab tshuaj txhuam
Conductive Gel / Muab Tshuaj Txhuam: Thov cov nyiaj tau me me los yog muab tshuaj txhuam hniav rau txhua qhov electrode lossis ncaj qha rau saum tawv taub hau ntawm cov cim me ntsis. Qhov no pab tswj cov hluav taws xob sib ze zoo ntawm cov tawv taub hau thiab cov electrode.
4. Muab cov electrodes tso
Khob Khob Khobes: Yog tias siv cov tshuab ntim khob, nias lawv maj mam mus rau cov cim me me rau saum tawv taub hau. Ua kom txhua txhua electrode nyob rau hauv qhov chaw zoo nyob rau hauv qhov chaw thiab ua rau kev sib cuag nrog tawv nqaij.
Cov nplaum lossis cov pob hluav taws xob: Rau cov roj hluav taws xob nplaum, tev tawm sab nraub qaum thiab lo rau saum tawv taub hau. Rau SNAP Electrodes, muab lawv siv cov kab txuas txuas.
5. Luag cov electrodes
Cap lossis Elastic Netting: Qee qhov kev teeb tsa EEG siv ib qho elastic cap lossis net los tuav cov electrodes nyob rau hauv qhov chaw, tshwj xeeb tshaj yog nyob rau hauv high-ceev eg teeb tsa. Xyuas kom meej lub hau tau ua raws li cov cim hluav taws xob.
Daim kab xev / Adhesive: Koj kuj tuaj yeem muaj hluav taws xob ntxiv nrog cov kab xev nplaum lossis cov tshuaj nplaum electrode.
6. Kos rau hauv hluav taws xob
Siv Eeg Tshuab: Txuas cov electrodes mus rau lub tshuab Eeg thiab tshawb xyuas lub impedance rau txhua electrode. Kev yuam yuav feem ntau yuav tsawg dua 5 kω (kilo-ohms) los xyuas kom lub teeb liab zoo.
Kho yog tias tsim nyog: Yog hais tias lub impedance yog dhau lawm, rov ntxuav cov tawv taub hau lossis ntxiv cov gel ntxiv.
7. Muab cov ntaub ntawv txuas nrog thiab hauv av
Kev Siv Hluav Taws Xob: Txuas cov ntaub ntawv siv electrode rau qhov chaw nruab nrab, xws li mastoids (tom qab pob ntseg) lossis eastobes.
Hauv av rau: Muab cov av electrode ntawm qhov chaw uas yuav tsis cuam tshuam nrog kev ntsuas kev ntsuas hlwb, xws li ntawm lub caj dab.
8. Txuas rau EEG CO TSHUAB
Ntsaws rau hauv electrodes: Txuas cov kev ua los ntawm cov electrodes rau Eeg Amplifier, tom qab cov haujlwm channel tsim nyog rau txhua txoj haujlwm electrode.
9. Saib Xyuas Teeb Liab Zoo
Kos teeb liab: Pib lub EEG kaw thiab saib xyuas lub teeb liab zoo. Xyuas kom muaj tsis muaj lub suab nrov lossis cov khoom cuav, thiab cov EEG WEBETFICS muaj tseeb thiab zoo ib yam.
Txhim Kho: Yog tias qee cov hluav taws xob tsis yog qhia cov teeb liab zoo, kho lawv, thov cov gel zoo dua, lossis rov muaj dua lawv.
10. Pib EEG Cov Ntaub Ntawv
Thaum cov hluav taws xob txhua qhov yog qhov chaw thiab teeb liab zoo yog txheeb xyuas, npaj nrog EEG kaw raws li kev kawm raws txoj kev kawm lossis kev tshawb fawb.
Lub ntsiab
Npaj tus neeg mob: Ntxuav lub taub hau thiab piav qhia cov txheej txheem.
Kos rau hauv electrode txoj haujlwm: Siv 10-20 system.
Thov Ua Yeeb Yam Gel / Paste: Los xyuas kom zoo rau kev tiv tauj zoo.
Qhov Chaw Hluav Taws Xob: Kev nyab xeeb lawv siv cov nplaum, lub kaus mom, lossis netting.
Txheeb xyuas kev quab yuam: Xyuas kom cov electrodes tau zoo sib txuas.
Saib Xyuas Teeb Liab: Txheeb xyuas lub teeb liab yog qhov tseeb ua ntej sau cia.
Yog qhov chaw nyob thiab kev sib cuag yog qhov tseem ceeb rau kev ntes cov kev ua lub hlwb thaum lub sijhawm kev soj ntsuam lub sijhawm Eeg saib xyuas.
