PPG tekinoroji yakavakirwa pakutarisisa yekuona tekinoroji inokwanisa kuwana ruzivo rwebasa remoyo pasina kuyera masaini ebioelectrical.Nheyo inokosha ndeyokuti sezvo mwoyo unorova, pachava nemasaisai ekumanikidza anopfuudzwa kuburikidza netsinga dzeropa.Iyi wave inoshandura zvishoma dhayamita yetsinga dzeropa.PPG yekutarisa inoshandisa shanduko iyi kuwana shanduko yemoyo pese painorova.PPG inonyanya kushandiswa kuyera kuzara kweokisijeni muropa (SpO2), saka inokwanisa kuwana kurova kwemoyo (kureva kurova kwemoyo) data yenyaya nenzira iri nyore.
Electrode-based ECG monitoring tekinoroji inoonekwa nebioelectricity, uye iyo inogona kutapurirana yemoyo inogona kuwonekwa nekushandisa maelectrodes akabatanidzwa pamusoro peganda remunhu.Mukutenderera kwemoyo wega wega, moyo unofadzwa zvakatevedzana ne pacemaker, atrium, uye ventricle, zvichiperekedzwa nekuchinja kwekuita kwekuita kwemasero asingaverengeki emyocardial.Idzi shanduko dzebioelectric dzinonzi ECG.Nekutora zvikwangwani zvebioelectric uye wozozvigadzirisa nedigital, zvinoshandurwa kuita Mushure medhijitari chiratidzo chekugadzirisa, inogona kuburitsa ruzivo rwakakwana uye rwakadzama rwehutano hwemoyo.
Mukuenzanisa: teknolojia yePPG yakavakirwa pakutarisa kwemaziso iri nyore uye yakaderera mumutengo, asi kururamisa kwedheta yakawanikwa haisi yakakwirira uye chete kukosha kwemoyo kunowanikwa.Nekudaro, iyo electrode-based ECG monitoring tekinoroji yakanyanya kuomarara, uye chiratidzo chakawanikwa chakanyatso uye chinosanganisira kutenderera kwemoyo wese, kusanganisira PQRST wave boka, saka mutengo wakakwira zvakare.Kune yakangwara inopfeka ECG yekutarisa, kana iwe uchida kuwana yakakwirira-chaiyo ECG masaini, yepamusoro-inoshanda ECG yakatsaurirwa chip yakakosha.Nekuda kwehupamhi hwehunyanzvi pachikumbaridzo, iyi yepamusoro-chaiyo chip parizvino inonyanya kushandiswa neTI yekune dzimwe nyika, Inopihwa nemakambani akadai seADI, machipisi epamba ane nzira refu yekuenda.
TI's ECG-chaiyo machipisi anosanganisira ADS129X akatevedzana, anosanganisira ADS1291 uye ADS1292 yezvishandiso zvinopfekwa.Iyo ADS129X yakatevedzana chip ine yakavakirwa-mukati 24-bit ADC, ine yakakwirira chiratidzo chechokwadi, asi iyo yakashata yekushandisa muzviitiko zvinopfekeka ndeiyi: saizi yepasuru yechip ichi yakakura, mashandisiro emagetsi akakura, uye kune akawanda. peripheral components.Pamusoro pezvo, kuita kwechip ichi muECG muunganidzwa uchishandisa masimbi emagetsi avhareji, uye kushandiswa kwesimbi electrode mune zvinopfekwa zvikumbiro hazvidzivisiki.Rimwe dambudziko rakakura neiyi nhevedzano yemachipisi nderekuti mutengo weyuniti mutengo wakakwira, kunyanya mumamiriro ekushomeka kwepakati, kuwanikwa kuri kushomeka uye mutengo unoramba wakakwira.
ADS's ECG-specific chips inosanganisira ADAS1000 uye AD8232, iyo AD8232 inotariswa kune zvinopfekwa zvikumbiro, nepo ADAS1000 ichinyanya kushandiswa kune yepamusoro-yekupedzisira michina yekurapa.ADAS1000 ine chiratidzo chemhando inofananidzwa neiyo ADS129X, asi mamwe matambudziko anosanganisira yakakwira mashandisiro emagetsi, mamwe maperipherals akaomarara uye yakakwira chip mitengo.AD8232 inonyanya kukodzera kune zvinopfekwa zvikumbiro maererano nekushandiswa kwesimba uye saizi.Kuenzaniswa neiyo ADS129X yakatevedzana, iyo chiratidzo chemhando yakasiyana.Zvakare mukuita kwekushandisa kwesimbi yakaoma electrode, iri nani algorithm inodiwa zvakare.Kushandisa maelectrode esimbi mune zvinopfekwa zvekushandisa, iko kurongeka kwechiratidzo kuri pakati uye pane kukanganisa, asi kana kungowana masaini emoyo chaiwo, iyi chip haina chimwe chinhu kunze kwekunyatsogutsa.
