Olu luvavanyo lokwenyani oluvela kumthengi waseAmazon.

Siyazi ukuba i-SpO₂ iyipharamitha ebalulekileyo ebonisa umsebenzi wokuphefumula womzimba kunye nokuba umxholo we-oksijini uyinto eqhelekileyo, kwaye i-oximeter sisixhobo esibeka iliso kwimo ye-oksijini yegazi emzimbeni wethu. I-oksijeni isisiseko semisebenzi yobomi, i-hypoxia yimbangela yezifo ezininzi, kunye nezifo ezininzi zingabangela ukunikezelwa kwe-oksijini eyaneleyo. I-SpO₂engaphantsi kwe-95% yimbonakaliso ye-hypoxia epholileyo. Ngaphantsi kwe-90% yi-hypoxia enzima kwaye kufuneka iphathwe ngokukhawuleza. Akunjalo kuphela abantu abadala abanomdla kwi-hypoxemia, kodwa abantu banamhlanje banoxinzelelo oluninzi lwengqondo kunye nomsebenzi kunye nexesha lokuphumla. Izitenxo zihlala zikhokelela kwi-hypoxemia. I-SpO₂ yexesha elide ephantsi iya kubangela ingozi enkulu kumzimba womntu. Ngoko ke, kuyimfuneko ukulinganisa i-SpO₂ emzimbeni rhoqo, nangona amanyathelo okukhusela athatyathwa.

Xa kuziwa kwii-oximeters, kubasebenzisi besitayela sasekhaya kunye neengcali zokuqina komzimba, abaninzi abantu baya kukhetha i-oximeters ephathekayo yeminwe, kuba i-exquisite, i-compact, ilula ukuyiphatha, kwaye ayinqunyelwe ixesha kunye nendawo. Iluncedo kakhulu kwaye iyakhawuleza. Ii-clip oximeters zeminwe zikwasetyenziswa kwiindawo ezininzi zonyango lobuchwephesha, kodwa iimfuno zokuchaneka ziphezulu. Ngoko ke, ukupheliswa kweempazamo ngenye yezinto eziphambili zokulinganisa okuqinileyo kwe-oximeter.

Ukuchaneka kwe-oximeter kuhambelana ngokusondeleyo nomgaqo wobugcisa obuchwephesha be-oximeter. Imigaqo yoyilo yababoneleli besisombululo se-oximeter yangoku kwimarike ngokusisiseko iyafana: ukusetyenziswa kwe-LED ebomvu, i-infrared LED kunye nokwakheka kwefotodiode ye-SpO₂ sensor circuit, kunye ne-LED drive circuit. Emva kokuba ukukhanya okubomvu kunye nokukhanya kwe-infrared kuhanjiswe ngomnwe, zichongwa yi-circuit processing circuit, kwaye zidluliselwe kwimodyuli ye-ADC ye-single-chip microcomputer ukubala ngakumbi ipesenti ye-SpO₂. Zonke zisebenzisa izinto ezibuthathaka ezikhanyayo ezifana nokukhanya okubomvu, ukukhanya kwe-infrared LED kunye nefotodiode ukulinganisa ukuhanjiswa kweminwe kunye neendlebe. Nangona kunjalo, ababoneleli besisombululo se-oximeter abanemigangatho ephezulu kunye neemfuno zeprogram baneemfuno ezingqongqo kunye nezifuna kakhulu uvavanyo. Ukongeza kwiindlela zovavanyo eziqhelekileyo ezikhankanywe ngasentla, kufuneka basebenzise iimveliso zabo zeprogram kunye nokulinganisa okusemgangathweni kwe-oximeter. Idatha ithelekiswa ne-oximeter ye-medical-grade.

I-oximeter ephuhliswe yi-MedLinket ifundwe ngeklinikhi kwizibhedlele ezifanelekileyo. Kuphononongo lwe-saturation olulawulwayo, i-SaO₂ yoluhlu lomlinganiselo wemveliso ye-70% ukuya kwi-100% iqinisekisiwe. Xa kuthelekiswa nexabiso le-SpO₂ ye-arterial elinganiswe yi-CO-Oximeter, idatha echanekileyo ifunyenwe. Iphutha le-SpO₂ lilawulwa kwi-2%, kwaye impazamo yeqondo lokushisa ilawulwa kwi-0.1 ℃, enokufikelela kumlinganiselo ochanekileyo we-SpO₂, ukushisa kunye ne-pulse. , Ukuhlangabezana neemfuno zomlinganiselo wobungcali.

Ukukhetha i-MedLinket enexabiso eliphantsi kunye nesisombululo esichanekileyo se-oximeter kwimarike, ndiyakholelwa ukuba iya kufumana ngokukhawuleza inkoliseko yabasebenzisi.
