Oximeter yolondola kwambiri yomwe imakumana ndi kuyezetsa kwachipatala, "chopulumutsa moyo" panthawi yovuta

Uku ndikuwunika kowona kuchokera kwa kasitomala ku Amazon.

Tikudziwa kuti SpO2 ndi gawo lofunikira lomwe limawonetsa momwe thupi limagwirira ntchito komanso ngati mpweya wa okosijeni ndi wabwinobwino, ndipo oximeter ndi chipangizo chomwe chimayang'anira momwe magazi amakhalira m'thupi lathu.Oxygen ndiye maziko a ntchito za moyo, hypoxia ndiye gwero la matenda ambiri, ndipo matenda ambiri angayambitsenso kuperewera kwa oxygen.SpO2otsika kuposa 95% ndi chiwonetsero cha hypoxia yofatsa.Pansi pa 90% ndi hypoxia yoopsa ndipo iyenera kuthandizidwa mwamsanga.Sikuti ndi okalamba okha omwe ali ndi hypoxemia, koma anthu amakono ali ndi nkhawa zambiri zamaganizo ndi ntchito ndi nthawi yopuma.Zolakwika nthawi zambiri zimayambitsa hypoxemia.Kutsika kwanthawi yayitali kwa SpO2 kungayambitse vuto lalikulu m'thupi la munthu.Chifukwa chake, ndikofunikira kuyeza SpO2 m'thupi pafupipafupi, ngakhale njira zodzitetezera zitatengedwa.

Pankhani ya oximeter, kwa ogwiritsa ntchito kunyumba komanso akatswiri olimbitsa thupi, anthu ambiri amasankha ma oximeter onyamula chala, chifukwa ndi okongola, ophatikizika, osavuta kunyamula, komanso osawerengeka ndi nthawi ndi malo.Zothandiza kwambiri komanso zachangu.Ma oximeter a zala amagwiritsidwanso ntchito m'malo ambiri azachipatala, koma zolondola ndizokwera kwambiri.Chifukwa chake, kuchotsa zolakwika ndi chimodzi mwazinthu zofunikira pakuyezera kolimba kwa oximeter.

Kulondola kwa oximeter kumagwirizana kwambiri ndi mfundo yaukadaulo ya oximeter.Mfundo za mapangidwe a oximeter amakono opereka yankho pamsika ndizofanana: kugwiritsa ntchito ma LED ofiira, infuraredi ya LED ndi mawonekedwe a photodiode a sensa ya SpO2, Kuphatikizana ndi dera lagalimoto la LED.Pambuyo pa kuwala kofiira ndi kuwala kwa infrared kufalikira kudzera pa chala, zimadziwika ndi kayendedwe ka ma signal, kenaka amaperekedwa ku ADC module ya single-chip microcomputer kuti apitirize kuwerengera kuchuluka kwa SpO2.Zonse zimagwiritsa ntchito zinthu zopepuka zopepuka monga kuwala kofiyira, kuwala kwa infrared LED ndi photodiode kuyeza kufalikira kwa nsonga ndi makutu.Komabe, opereka mayankho a oximeter omwe ali ndi miyezo yapamwamba komanso zofunikira pa pulogalamuyi amakhala ndi zofunikira zoyeserera.Kuphatikiza pa njira zoyeserera zomwe zatchulidwa pamwambapa, ayenera kugwiritsa ntchito mapulogalamu awoawo komanso zoyeserera zaukadaulo za oximeter.Deta imayerekezedwa ndi oximeter yachipatala.

Oximeter yopangidwa ndi Medlinket yaphunziridwa mwachipatala m'zipatala zoyenerera.Mu kafukufuku wowongolera machulukitsidwe, SaO2 ya muyeso wamtundu wa 70% mpaka 100% watsimikiziridwa.Poyerekeza ndi mtengo wa SpO2 woyezedwa ndi CO-Oximeter, deta yolondola imapezedwa.Cholakwika cha SpO2 chimayang'aniridwa pa 2%, ndipo cholakwika cha kutentha chimayendetsedwa pa 0.1 ℃, chomwe chingathe kukwaniritsa muyeso wolondola wa SpO2, kutentha, ndi kugunda., Kukwaniritsa zosowa za kuyeza akatswiri.

Kusankha njira ya Medlinket yotsika mtengo komanso yolondola yoyezera oximeter pamsika, ndikukhulupirira kuti ipeza mwayi kwa ogwiritsa ntchito.
