Dziwani zambiri za HME Fyuluta

A Chosinthira chinyezi cha kutentha (HME)ndi njira imodzi yoperekera chinyezi kwa odwala akuluakulu a tracheostomy. Kusunga chinyezi m'njira yolowera mpweya ndikofunikira chifukwa kumathandiza kuti madzi atuluke pang'ono kuti atuluke. Njira zina zoperekera chinyezi m'njira yolowera mpweya ziyenera kugwiritsidwa ntchito pamene HME palibe.

Zigawo zaZosefera za HEM

Zigawo za zosefera za HME zimapangidwa mosamala kuti zitsimikizire kuti zikugwira ntchito bwino. Nthawi zambiri, zoseferazi zimakhala ndi chipinda chosungiramo zinthu, malo osungiramo zinthu zoyera, ndi chipinda chosungiramo zinthu zoyera/zoyera. Chipindacho chimapangidwa kuti chiteteze bwino fyuluta mkati mwa wodwalayo.dera lopumiraZipangizo zoyezera mpweya (Hygroscopic media) nthawi zambiri zimapangidwa kuchokera ku zinthu zosagwirizana ndi madzi zomwe zimagwira bwino ndikusunga chinyezi chomwe chimatuluka. Nthawi yomweyo, fyuluta ya bakiteriya/mavairasi imagwira ntchito ngati chotchinga, kuteteza kuti tizilombo toyambitsa matenda ndi tinthu toopsa tisadutse.

Zinthu Zaukadaulo za Zosefera za HME:

Fyuluta ya HME imagwiritsidwa ntchito pa ma circuits opumira odwala kuti apewe kuipitsidwa kulikonse.

Yoyenera odwala omwe ali ndi tracheostomy chubu omwe amapuma modzidzimutsa.

Malo osefera ogwira ntchito: 27.3cm3

Luer Port kuti mupeze mosavuta kusanthula mpweya pogwiritsa ntchito chivundikiro chomangiriridwa kuti muchepetse chiopsezo chotayika.

Kapangidwe kozungulira koyenera kopanda m'mbali zakuthwa kumachepetsa zizindikiro za kupanikizika.

Kapangidwe kakang'ono kamachepetsa kulemera kwa seti.

Kukana kuyenda bwino kwa madzi kumachepetsa kupuma

Kawirikawiri imakhala ndi thovu kapena pepala lokhala ndi mchere wa hydroscopic monga calcium chloride

Zosefera za mabakiteriya ndi mavairasi zimakhala ndi mphamvu yosefera ya >99.9%

HME yokhala ndi mphamvu yonyowetsa chinyezi >30mg.H2O/L

Imalumikizidwa ku cholumikizira cha 15mm chokhazikika pa chubu cha endotracheal

Njira yotenthetsera ndi chinyezi

Muli thovu kapena pepala lokhala ndi mchere wofanana ndi calcium chloride

Mpweya wotha ntchito umazizira pamene ukudutsa nembanemba, zomwe zimapangitsa kuti mpweya wambiri wa nthunzi utuluke ndi kutuluka kwa mpweya wochuluka wa nthunzi kupita ku HME layer.

Pakupumira, kutentha komwe kumayamwa kumasanduka nthunzi ya condensate ndikutenthetsa mpweya, mchere wa hygroscopic umatulutsa mamolekyu amadzi pamene mphamvu ya nthunzi ili yochepa.

Kutentha ndi chinyezi zimayendetsedwa ndi kuchuluka kwa mpweya womwe watha ntchito komanso kutentha kwa wodwalayo.

Palinso fyuluta, yomwe imakhala ndi mphamvu zamagetsi kapena yokhala ndi ma pleated hydrophobic layer, yomwe imathandiza kubweza chinyezi ku mpweya pamene mpweya umalowa ndi kutuluka madzi pakati pa ma pleats.

Njira yosefera

Kusefa kumachitika pa tinthu tating'onoting'ono tating'onoting'ono (> 0.3 µm) pogwiritsa ntchito inertial impaction ndi interception.

Tinthu tating'onoting'ono (<0.3 µm) timagwidwa ndi kufalikira kwa Brownian

Kugwiritsa Ntchito Zosefera za HME

Amagwiritsidwa ntchito kwambiri m'zipatala, m'zipatala, komanso m'malo osamalira odwala kunyumba. Zoseferazi nthawi zambiri zimaphatikizidwa mu ma circuits a ventilator, ma anesthesia breathing systems, ndi ma tracheostomy tubes. Kusinthasintha kwawo komanso kugwirizana kwawo ndi zida zosiyanasiyana zopumira kumapangitsa kuti zikhale gawo lofunikira kwambiri pa chisamaliro cha kupuma.

Monga wogulitsa wamkulu komanso wopangazinthu zogwiritsidwa ntchito zachipatalaShanghai Teamstand Corporation yadzipereka kupereka zosefera za HME zapamwamba kwambiri zomwe zimakwaniritsa zofunikira za akatswiri azaumoyo. Zogulitsa zawo zimapangidwa ndi cholinga chofuna kuti odwala azikhala omasuka, ogwira ntchito bwino kuchipatala komanso kupewa matenda, zomwe zimapangitsa kuti zikhale chisankho chodalirika cha zipatala padziko lonse lapansi.

Timapereka mitundu yosiyanasiyana ya ma HMEF okhala ndi magwiridwe antchito osiyanasiyana, kukula ndi mawonekedwe kuti titsimikizire kuti makasitomala athu amasankha bwino kwambiri pamene tikukwaniritsa zofunikira zonse zachipatala.
