Dziwani zambiri za Zosefera za HME

A Heat Moisture Exchanger (HME)ndi njira imodzi yoperekera chinyezi kwa odwala akuluakulu a tracheostomy. Kusunga mpweya wonyowa ndikofunikira chifukwa kumathandizira katulutsidwe kakang'ono kuti akosokere. Njira zina zoperekera chinyezi kunjira yopita kumlengalenga ziyenera kugwiritsidwa ntchito pomwe HME palibe.

Zigawo zaZosefera za HEM

Zigawo za zosefera za HME zimapangidwa mosamala kuti zitsimikizire kuti zikuyenda bwino. Nthawi zambiri, zoseferazi zimakhala ndi nyumba, media media, ndi chosanjikiza cha bakiteriya / ma virus. Nyumbayo idapangidwa kuti iteteze bwino fyuluta mkati mwa wodwalakupuma dera. Ma media a Hygroscopic nthawi zambiri amapangidwa kuchokera ku zida za hydrophobic zomwe zimagwira bwino ndikusunga chinyezi chotuluka. Pa nthawi yomweyo, bakiteriya / mavairasi fyuluta wosanjikiza amachita ngati chotchinga, kuteteza ndimeyi wa zoipa tizilombo ndi particles.

Zaukadaulo Zazosefera za HME:

HME fyuluta imagwiritsidwa ntchito pamayendedwe opumira odwala kuti apewe kuipitsidwa kulikonse.

Zoyenera kwa odwala kupuma modzidzimutsa ndi tracheostomy chubu.

Malo osefa bwino: 27.3cm3

Luer Port ya zitsanzo zosavuta za gasi zokhala ndi kapu yotsekeredwa kuti muchepetse chiopsezo chosokonekera.

Mawonekedwe ozungulira a ergonomic opanda m'mphepete akuthwa amachepetsa kuyika chizindikiro.

Mapangidwe apakatikati amachepetsa kulemera kwa dera.

Kutsika kukana kuyenda kumachepetsa ntchito ya kupuma

Nthawi zambiri imakhala ndi chithovu kapena pepala lokhala ndi mchere wa hydroscopic monga calcium chloride

Zosefera za mabakiteriya ndi ma virus zimakhala ndi kusefera kwa> 99.9%

HME yokhala ndi chinyezi chokwanira >30mg.H2O/L

Imalumikizana ndi cholumikizira chokhazikika cha 15mm pa chubu cha endotracheal

Njira yowotchera ndi chinyezi

Muli wosanjikiza wa thovu kapena pepala lokhala ndi mchere wa hygroscopic monga calcium chloride

Mpweya wotha ntchito umazizira pamene ukuwoloka nembanemba, zomwe zimapangitsa kuti pakhale condensation ndi kutulutsidwa kwa enthalpy ya vaporisation ku HME wosanjikiza.

Pa kudzoza kutentha komwe kumalowa kumatulutsa mpweya wa condensate ndikutenthetsa mpweya, mchere wa hygroscopic umatulutsa mamolekyu amadzi pamene mpweya wa mpweya uli wotsika.

Kutentha ndi chinyezi kumayendetsedwa ndi chinyezi cha gasi yomwe yatha komanso kutentha kwapakati kwa wodwala.

Chosanjikiza chosefera chiliponso, chopangidwa ndi electrostatically charged kapena pleated hydrophobic layer, chotsiriziracho chimathandizira kubwezera chinyezi ku gasi chifukwa kukhazikika komanso kuphulika kumachitika pakati pa ma pleats.

Njira yosefera

Kusefera kumatheka pa tinthu tating'onoting'ono tokulirapo (> 0.3 µm) mwa kugunda kwamphamvu ndi kutsekeka.

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

Kugwiritsa ntchito Zosefera za HME

Amagwiritsidwa ntchito kwambiri m'zipatala, zipatala, ndi malo osamalira kunyumba. Zosefera izi nthawi zambiri zimaphatikizidwa mumayendedwe olowera mpweya, makina opumira a anesthesia, ndi machubu a tracheostomy. Kusinthasintha kwawo komanso kuyanjana ndi zida zosiyanasiyana zopumira kumawapangitsa kukhala gawo lofunikira la chisamaliro cha kupuma.

Monga ogulitsa otsogola komanso opangamankhwala ophera mankhwala, Shanghai Teamstand Corporation yadzipereka kupereka zosefera zapamwamba za HME zomwe zimakwaniritsa zofunikira za akatswiri azaumoyo. Zogulitsa zawo zimapangidwa ndi cholinga cha chitonthozo cha odwala, mphamvu zachipatala komanso kuwongolera matenda, kuwapanga kukhala chisankho chodalirika chazipatala padziko lonse lapansi.

Timapereka kusankha kwakukulu komanso kokwanira kwa ma HMEF okhala ndi magwiridwe antchito, makulidwe ndi mawonekedwe osiyanasiyana kuti tiwonetsetse kusankha kwamakasitomala kwambiri ndikukwaniritsa zofunikira zonse zachipatala.
