Ikigo gishinzwe kugenzura ubuvuzi ECG
Ibisobanuro
Ikoranabuhanga rya PPG rishingiye ku kugenzura optique ni tekinoroji ya optique ishobora kubona amakuru yimikorere yumutima idapima ibimenyetso bya bioelectrical.Ihame shingiro nuko uko umutima utera, hazabaho imiraba yumuvuduko yandurira mumitsi yamaraso.Uyu muhengeri uzahindura gato diameter yimitsi yamaraso.Gukurikirana PPG ikoresha iyi mpinduka kugirango ubone impinduka z'umutima igihe cyose ikubise.PPG ikoreshwa cyane mugupima ubwinshi bwamaraso ya ogisijeni (SpO2), bityo irashobora kubona umuvuduko wumutima (ni ukuvuga umutima utera) amakuru yibintu muburyo bworoshye.
Ikoreshwa rya elegitoroniki ya ECG ikurikirana ikoreshwa na bioelectricity, kandi kwanduza umutima gushobora kumenyekana ukoresheje electrode ifatanye hejuru yuruhu rwumuntu.Muri buri cyiciro cyumutima, umutima ushimishwa bikurikiranye na pacemaker, atrium, na ventricle, biherekejwe nimpinduka mubushobozi bwibikorwa bya selile zitabarika za myocardial.Izi mpinduka za bioelectric zitwa ECG.Gufata ibimenyetso bya bioelectric hanyuma ukabitunganya muburyo bwa digitale, bihindurwa Nyuma yo gutunganya ibimenyetso bya digitale, birashobora gutanga amakuru yukuri kandi arambuye yubuzima bwumutima.
Mugereranije: tekinoroji ya PPG ishingiye kubikurikirana optique iroroshye kandi iri hasi kubiciro, ariko ukuri kwamakuru yabonetse ntabwo ari hejuru kandi haboneka agaciro k'umutima gusa.Nyamara, tekinoroji ya electrode ishingiye kuri electrode irakomeye cyane, kandi ibimenyetso byabonetse birasobanutse neza kandi birimo uruziga rwose rwumutima, harimo nitsinda rya PQRST, bityo igiciro nacyo kiri hejuru.Kugenzura ubwenge bworoshye kwambara ECG, niba ushaka kubona ibimenyetso-byuzuye bya ECG, chip-ikora cyane ECG yihariye ni ngombwa.Bitewe nubuhanga buhanitse, iyi chip-precision chip ikoreshwa cyane cyane muri TI yo mumahanga, Itangwa namasosiyete nka ADI, chip zo murugo zifite inzira ndende.
TI ya ECG yihariye ikubiyemo urutonde rwa ADS129X, harimo ADS1291 na ADS1292 kubishobora kwambara.Chip yuruhererekane rwa ADS129X ifite ibyubatswe muri 24-biti ya ADC, ifite ibimenyetso byerekana neza ukuri, ariko ibibi byo gukoresha mugihe cyambarwa ni: ingano yipaki yiyi chip ni nini, gukoresha ingufu ni nini, kandi haribenshi ugereranije Ibice bya periferi.Mubyongeyeho, imikorere yiyi chip mugukusanya ECG ukoresheje electrode yicyuma ni impuzandengo, kandi gukoresha electrode yicyuma mubishobora kwambara byanze bikunze.Ikindi kibazo gikomeye hamwe nuruhererekane rwa chipi ni uko igiciro cyibiciro kiri hejuru cyane, cyane cyane mubijyanye n’ibura ry’ibanze, itangwa rirahagije kandi igiciro gikomeza kuba kinini.
Chip yihariye ya ADS ya ADS irimo ADAS1000 na AD8232, muri zo AD8232 igenewe porogaramu zishobora kwambarwa, mugihe ADAS1000 ikoreshwa cyane mubikoresho byubuvuzi byo mu rwego rwo hejuru.ADAS1000 ifite ubuziranenge bwibimenyetso ugereranije nubwa ADS129X, ariko ibibazo byinshi birimo gukoresha ingufu nyinshi, periferique igoye hamwe nigiciro kinini cya chip.AD8232 irakwiriye cyane kubishobora kwambara mubijyanye no gukoresha ingufu nubunini.Ugereranije nuruhererekane rwa ADS129X, ubwiza bwibimenyetso buratandukanye cyane.Na none mubikorwa byo gukoresha ibyuma byumye electrode, algorithm nayo irakenewe.Gukoresha icyuma cya electrode yicyuma gishobora kwambarwa, ibimenyetso byerekana neza ni impuzandengo kandi hariho kugoreka, ariko niba gusa kubona ibimenyetso byerekana umuvuduko wumutima, iyi chip ntakindi kirenze kunyurwa rwose.
