Imikorere nihame ryamaraso ya ogisijeni

1. Imikorere n'ihame

Ukurikije ibimenyetso biranga oxyhemoglobine (HbO2) no kugabanya hemoglobine (Hb) mu mucyo utukura no mu turere tw’umucyo utagaragara, dushobora kubona ko kwinjiza HbO2 na Hb mu mucyo utukura (600-700nm) bitandukanye cyane, no kwinjiza urumuri no gukwirakwiza urumuri Amaraso Urwego rushingiye cyane ku kuzura kwa ogisijeni mu maraso;mugihe mukarere ka infragre (800 ～ 1000nm), kwinjiza biratandukanye cyane.Urwego rwo kwinjiza urumuri no gukwirakwiza urumuri rwamaraso ahanini bifitanye isano nibiri muri hemoglobine.Kubwibyo, ibiri muri HbO2 na Hb biratandukanye mukwinjira.Ikirangantego nacyo kiratandukanye, bityo amaraso ari muri catheter yamaraso ya oximeter arashobora kwerekana neza ubwuzure bwamaraso ya ogisijeni ukurikije ibikubiye muri HbO2 na Hb, yaba amaraso ya arterial cyangwa kuzura amaraso.Ikigereranyo cyerekana amaraso agera kuri 660nm na 900nm (ρ660 / 900) kigaragaza cyane impinduka zuzuye mu kuzura kwa ogisijeni mu maraso, hamwe na metero zuzuye zuzuye za ogisijeni mu maraso (nka metero zuzuye za Baxter) nazo zikoresha iri gereranya nkimpinduka.Mu nzira yo gukwirakwiza urumuri, usibye na hemoglobine ya arterial ikurura urumuri, izindi ngingo (nk'uruhu, inyama zoroshye, amaraso y'amaraso n'amaraso ya capillary) nazo zishobora gukuramo urumuri.Ariko iyo urumuri rwibyabaye runyuze mu rutoki cyangwa ku gutwi, urumuri rushobora kwinjizwa namaraso ya pulsatile hamwe nizindi ngingo icyarimwe, ariko ubukana bwurumuri bwakiriwe byombi buratandukanye.Imbaraga zumucyo (AC) zinjizwa namaraso ya pulsatile arterial ihinduka hamwe nimpinduka yumuvuduko wumuvuduko wa arterial Kandi ugahinduka.Imbaraga zumucyo (DC) zinjijwe nizindi ngingo ntizihinduka hamwe nimpiswi nigihe.Kuva aha, igipimo cyo kwinjiza urumuri R muburebure bwumurongo wa kabiri kirashobora kubarwa.R = (AC660 / DC660) / (AC940 / DC940).R na SPO2 bifitanye isano mbi.Ukurikije agaciro R, agaciro ka SPO2 gashobora kuboneka uhereye kumurongo usanzwe.

2. Ibiranga nibyiza bya anketi

Igikoresho cya SPO2 gikubiyemo ibintu bitatu byingenzi: iperereza, imikorere yimikorere nigice cyo kwerekana.Kubakurikirana benshi kumasoko, tekinoroji yo kumenya SPO2 yamaze gukura cyane.Ubusobanuro bwagaciro ka SPO2 bwagaragajwe na monite ahanini bufitanye isano nubushakashatsi.Hariho ibintu byinshi bigira ingaruka ku gutahura iperereza.Igikoresho cyo gutahura, insinga z'ubuvuzi, hamwe na tekinoroji yo guhuza ikoreshwa na probe bizagira ingaruka kubisubizo.

A · Igikoresho cyo kumenya

Diode itanga urumuri hamwe na fotodetekeri yerekana ibimenyetso nibintu byingenzi bigize iperereza.Ninurufunguzo rwo kumenya ukuri kwagaciro.Mubyigisho, uburebure bwumucyo wumutuku ni 660nm, kandi agaciro kabonetse mugihe urumuri rwa infragre ni 940nm nibyiza.Nyamara, bitewe nuburyo bugoye bwo gukora igikoresho, uburebure bwumucyo wumucyo utukura numucyo utagira urumuri byakozwe buri gihe biratandukana.Ubunini bwo gutandukana kwurumuri rwumucyo bizagira ingaruka kubigaragara.Kubwibyo, uburyo bwo gukora diode isohora urumuri nibikoresho byerekana amafoto ni ngombwa cyane.R-RUI ikoresha ibikoresho byo gupima FLUKE, ifite ibyiza haba mubyukuri kandi byizewe.

B · Umugozi wubuvuzi

Usibye gukoresha ibikoresho byatumijwe mu mahanga (byizewe ukurikije imbaraga za elastique nyinshi hamwe no kurwanya ruswa), byateguwe kandi hamwe no gukingira ibice bibiri, bishobora guhagarika urusaku kandi bigakomeza ibimenyetso bitagereranywa ugereranije n'umurongo umwe cyangwa nta gukingira.

Cushion

Iperereza ryakozwe na R-RUI rikoresha igikoresho cyoroshye cyabigenewe (urutoki), cyoroshye, cyizewe, kandi kitari allergeque gihuye nuruhu, kandi gishobora gukoreshwa kubarwayi bafite imiterere itandukanye.Kandi ikoresha igishushanyo cyuzuye cyuzuye kugirango wirinde kwivanga guterwa no kuva kumucyo bitewe no kugenda kwintoki.

D clip y'intoki

Igice cy'intoki z'umubiri gikozwe mu bikoresho birwanya umuriro bidafite ubumara bwa ABS, bukomeye kandi ntibyoroshye kwangiza.Isahani ikingira urumuri nayo yateguwe kuri clip yintoki, ishobora gukingira neza inkomoko yumucyo.

E · Isoko

Mubisanzwe, imwe mumpamvu nyamukuru zitera kwangirika kwa SPO2 nuko amasoko arekuye, kandi elastique ntabwo ihagije kugirango imbaraga zifatika zidahagije.R-RUI ikoresha amashanyarazi menshi ya karubone ibyuma, byizewe kandi biramba.

F terminal

Kugirango hamenyekane ihuza ryizewe kandi rirambye ryiperereza, kwiyegereza inzira yo kohereza ibimenyetso birasuzumwa kuri terefone ihuza na monitor, kandi hafashwe ingamba zidasanzwe zometseho zahabu.

G · Guhuza inzira

Guhuza inzira yubushakashatsi nabyo ni ngombwa cyane kubisubizo byikizamini.Imyanya ya padi yoroshye yarahinduwe kandi irageragezwa kugirango hamenyekane neza imyanya yohereza no kwakira ibikoresho byipimisha.

H · Kubijyanye nukuri

Menya neza ko iyo agaciro ka SPO2 ari 70% ~~ 100%, ikosa ntirenza plus cyangwa gukuramo 2%, kandi ubunyangamugayo buri hejuru, kugirango ibisubizo byerekana neza.
