Ukukhiqizwa kwe-PCB Yokurekhoda ye-ECG Egqokwayo Yama-Patches Ahamba Ngomuntu Oyedwa, Amadivayisi e-Holter kanye Namarekhodi Emicimbi

I-PCB yerekhoda ye-ECG egqokwayo ilinganisa izimpawu ezincane ze-biopotential zenhliziyo ngama-electrode omzimba ngenkathi isebenza kusuka ebhethri elincane amahora noma izinsuku. Kuye ngomkhiqizo, izinto zikagesi zingaba yi-patch yokunamathisela ene-lead eyodwa, irekhoda ye-Holter enama-electrode amaningi, i-monitor egqokwa esifubeni noma i-event recorder ene-Bluetooth kanye nememori yendawo. Umklamo kumele ulinganisele umsindo wokufaka ophansi, ukutholwa kwe-lead-off, ukubekezelela ukunyakaza kwezinto ezinyakazayo, i-interface ye-electrode ephephile esigulini, isikhathi eside sokusebenza kanye nendawo encane egqokwayo.

I-Highleap Electronics ikhiqiza amabhodi okurekhoda e-ECG aklanywe ngamakhasimende kanye nama-PCBA, okuhlanganisa iziphetho zangaphambili ze-analog ezinomsindo ophansi, ukuxhumana kwe-electrode okuguquguqukayo, amasekethe e-BLE/MCU, inkumbulo kanye nokuphathwa kwebhethri. Ukukhiqiza kungasekela i-prototype ngokukhiqiza okuphindaphindiwe ngemibhalo yekhwalithi yezokwelapha echazwe ngamakhasimende lapho kudingeka khona. Ukuxilongwa kwe-ECG, ukutholwa kwe-arrhythmia, ukunemba kwezokwelapha, ukuhambisana kwezinto eziphilayo kanye nokuvunyelwa kwedivayisi yezokwelapha kuhlala ohlelweni oluphelele lwe-OEM kanye nohlelo lokulawula.

Izinhlobo Zomkhiqizo Werekhoda Ye-ECG Egqokwayo kanye Nokucushwa Kwe-Electrode

Imikhiqizo ye-ECG egqokwayo isebenzisa ukubalwa kwama-electrode ahlukene, ubude bokurekhoda kanye nezindlela zedatha. Ukwakheka kwe-PCBA kufanele kuchazwe ngendlela yokuqopha ehlosiwe kunokuphathwa njengebhodi elilodwa elijwayelekile le-heart-monitor.

• Ipheshi le-ECG elihamba ngomthofu owodwa: Isebenzisa izindawo ezimbili noma ezintathu zokuthintana komzimba, i-AFE encane, i-MCU, inkumbulo kanye nebhethri elincane elisesinamathiselweni esigqokwayo esinamathelayo.
