Imitha ye-SpO2 ihlanganisa izingxenye ezintathu eziyinhloko: i-probe, imojula yokusebenza kanye nengxenye yokubonisa.Kwabaqaphi abaningi emakethe, ubuchwepheshe bokubona i-SpO2 sebuvuthwe kakhulu.Ukunemba kwe-I-SpO2inani elitholwe imonitha lihlobene kakhulu nophenyo.
(1) Idivayisi yokutholwa: I-diode ekhipha ukukhanya kanye nedivayisi ye-photodetector ethola isignali izingxenye eziyinhloko ze-probe.Kuphinde kube ukhiye wokunquma ukunemba kwevelu yokuthola.Ngokombono, ubude begagasi bokukhanya okubomvu bungu-660nm, futhi inani elitholwa lapho ukukhanya kwe-infrared kungu-940nm lilungile.Nokho, ngenxa yobunkimbinkimbi benqubo yokukhiqiza idivayisi, ubude beza beza lokukhanya okubomvu nokukhanya kwe-infrared okukhiqizwayo buhlala buchezukile.Ubukhulu bokuchezuka kobude begagasi lokukhanya buzothinta inani elitholiwe.Ngakho-ke, inqubo yokukhiqiza ama-diode akhipha ukukhanya kanye namadivayisi okubona i-photoelectric ibaluleke kakhulu.I-R-RUI isebenzisa imishini yokuhlola ye-Fulco, enezinzuzo kokubili ngokunemba nokwethembeka.
(2) Intambo yezokwelapha: Ngaphezu kokusebenzisa izinto ezingenisiwe (ethembekile ngokwamandla anwebekayo aphezulu kanye nokumelana nokugqwala), iphinde yakhelwe ngokuvikela okukabili, okungacindezela ukuphazamiseka komsindo futhi igcine isignali iqinile uma iqhathaniswa nongqimba olulodwa. noma kungekho isivikelo.
(3) Iphedi ethambile: I-probe ekhiqizwe yi-R-RUI isebenzisa iphedi ethambile eklanywe ngokukhethekile (iphedi yeminwe), enethezekile, ethembekile, futhi engeyona i-allergenic lapho ithinta isikhumba, futhi ifanele iziguli ezinemimo ehlukene.Futhi isebenzisa idizayini egoqwe ngokugcwele ukugwema ukuphazamiseka okubangelwa ukuvuza kokukhanya ngenxa yokunyakaza kweminwe.
(4) Isiqeshana somunwe: Isiqeshana somunwe senziwa ngento ye-ABS engashi, eqinile futhi akulula ukuyilimaza.Ipuleti elivikela ukukhanya liphinde laklanywa kusiqeshana somunwe, esingavikela kangcono umthombo wokukhanya okuzungezile.
(5) Ngokuvamile, esinye sezizathu eziyinhloko zeI-SpO2umonakalo wukuthi intwasahlobo ikhululekile, futhi ukunwebeka akwanele ukwenza amandla okubamba anganele.I-R-RUI isebenzisa i-high-tension electroplated carbon steel spring, ethembekile futhi ehlala isikhathi eside.
(6)Itheminali: Ukuze uqinisekise ukuxhumeka okuthembekile nokuqina kwe-probe, cabangela ukuncishiswa kwenqubo yokudlulisa isignali kutheminali yokuxhuma nemonitha, futhi wamukele inqubo ekhethekile itheminali egqitshwe ngegolide.
(7) Inqubo yokuxhuma: Inqubo yokuxhuma ye-probe nayo ibaluleke kakhulu emiphumeleni yokuhlolwa.Ukuma kwamaphedi athambile kuye kwalinganiswa futhi kwahlolwa ukuze kuqinisekiswe izindawo ezifanele zesidlulisi kanye nomamukeli wedivayisi yokuhlola.
(8) Ngokwemibandela yokunemba, qinisekisa ukuthi lapho i-I-SpO2inani lingu-70% -100%, iphutha alidluli ukuhlanganisa noma ukususa u-2%, futhi ukunemba kuphezulu, ukuze umphumela wokutholwa uthembeke kakhulu.
