ULWAZI LWE-ODOLAKutheni Sifanele Sisebenzise ii-Electrodes ze-Offset ECG?
Xa izigulana zichongwa nge-holter ECG kunye ne-telemetric ECG monitor, ngenxa yokuvela kokungqubana kweempahla, ukuxhuzula okuleleyo, kunye nokutsala, kubangela ukuphazamiseka okwenziwayo [1] kwisignali ye-ECG, okwenza kube nzima ngakumbi koogqirha ukuyixilonga.
Ukusebenzisa ii-electrode ze-ECG ezingasebenziyo kunokunciphisa kakhulu ukuphazamiseka kwezinto ezisetyenzisiweyo kwaye kuphucule umgangatho wokufunyanwa kwesignali ye-ECG eluhlaza, ngaloo ndlela kunciphisa izinga lokuxilongwa kwesifo sentliziyo okungaphoswanga kuvavanyo lwe-holter kunye nee-alamu zobuxoki ekubekweni kweliso kwe-ECG ye-telemetric ngoogqirha [2].
Umzobo woLwakhiwo lwe-Electrode ye-Offset ECG
Iingenelo zeMveliso
Ithembekile:Uyilo lokufakela i-offset, indawo ephumelelayo yokutsala i-buffer, ithintela kakhulu ukuphazamiseka kwezinto ezishukumayo, iqinisekisa ukuba isignali izinzile kwaye ithembekile.
Isitali：Inkqubo yokuprinta i-Ag/AgCL enelungelo lobunikazi, ekhawulezayo ngokufumanisa ukuxhathisa, iqinisekisa uzinzo lokudluliselwa kwedatha ixesha elide.
Ikhululekile:Ukuthamba ngokubanzi: umqolo ongalukwanga ngonyango, othambileyo nophefumlayo, uluncedo ngakumbi ekukhupheni umphunga kwaye uphucule inqanaba lokuthuthuzela kwesigulana.
Uvavanyo lokuthelekisa: I-Offset ECG Electrode kunye ne-Center ECG Electrode
Uvavanyo lokuThepha:
| I-Electrode ye-ECG yeZiko | I-Electrode ye-ECG ye-Offset |
 |  |
| Xa isigulana silele tyaba, siqhagamshelwe kwintambo ye-ECG, senza uxinzelelo kwi-hydrogel eqhubayo, emva koko kukho utshintsho ekuchaseni koqhagamshelwano olujikeleze i-hydrogel eqhubayo. | Xa isigulana silele tyaba, kwaye siqhagamshelwe kwintambo ye-ECG, asiyicinezeli i-hydrogel eqhubayo, engayichaphazeli kangako impembelelo yokumelana noqhagamshelwano olujikeleze i-hydrogel eqhubayo. |
| Ukusebenzisa isilinganisi ngokwahlukeneyo cofa kwiikhonkco ze-offset ECG electrodes kunye ne-Center fitting ECG electrodes rhoqo emva kwemizuzwana emi-4, kwaye ii-ECG ezifunyenweyo zezi zilandelayo: | |
 | |
| Iziphumo:Isignali ye-ECG itshintshe kakhulu, isantya sokujikeleza kwesiseko saya kwi-7000uV. | Iziphumo:Isignali ye-ECG ayichaphazeleki, iqhubeka nokuvelisa idatha ethembekileyo ye-ECG. |
Uvavanyo lokutsala

| Xa intambo ye-ECG itsalwa, i-force Fa1 isebenza kwi-skin-gel interface kunye ne-AgCLelectrode-gel interface, xa i-sensor ye-AgCL kunye ne-conductive hydrogel zisuswa kukutsalwa, zombini ziphazamisana noqhagamshelwano lombane nolusu, zize zivelise izinto zesignali ze-ECG. | Xa kutsalwa ucingo lwe-ECG, i-force Fa2 isebenza kwi-interface ye-gel enamathelayo kwisikhumba, ayinyamalali kummandla we-hydrogel oqhubayo, ngoko ke ivelisa izinto ezimbalwa eziveliswayo. |
Kwicala elithe nkqo kwi-skin sensor plane, ngamandla e-F=1N, i-leadwire ye-ECG kwi-electrode esembindini kunye ne-electrode engaqhelekanga zitsalwa ngokwahlukeneyo malunga nemizuzwana emi-3, kwaye ii-ECG ezifunyenweyo zezi zilandelayo: | |
| Imiqondiso ye-ECG eveliswa zii-electrode ezimbini yayibonakala ifana nqwa ngaphambi kokuba kutsalwe iintambo ze-lead. | |
| Iziphumo:Emva kokutsalwa kwesibini kwe-ECGleadwire, isignali ye-ECG ibonise ngoko nangoko ukushukuma kwesiseko ukuya kwi-7000uV. Ukushukuma kwesiseko okunokwenzeka ukuya kwi-±1000uV kwaye ii-boes azikwazi ukuphinda zibuyele kwisimo sokungazinzi kwesignali. | Iziphumo:Emva kokutsalwa kwesibini kwe-ECGleadwire, isignali ye-ECG ibonise ukuhla okwethutyana kwe-1000uV, kodwa isignali yabuya ngokukhawuleza kwimizuzwana eyi-0.1. |

2. Iwebhusayithi ingabhekisa kwiinkampani zangaphandle kunye neebhrendi ezinganxulumananga nathi nangayiphi na indlela. Imifanekiso yemveliso yenzelwe iinjongo zokubonisa kuphela kwaye inokwahluka kwizinto zokwenyani (umz., umahluko kwimbonakalo okanye umbala wesixhumi). Kwimeko apho kukho nakuphi na ukungangqinelani, imveliso yokwenyani iya kuphumelela.
