Chipangizo chomwe chimagwiritsidwa ntchito popereka chithandizo cha okosijeni chomwe chimatha kupereka mpweya wambiri wa okosijeni wopitilira 90% pamlingo wothamanga wofanana ndi 1 mpaka 5 L/min.
Ndizofanana ndi makina opangira oxygen kunyumba (OC), koma ang'onoang'ono komanso othamanga kwambiri. Ndipo chifukwa ndi yaying'ono mokwanira / yonyamula, mitundu yambiri tsopano yatsimikiziridwa ndi Federal Aviation Administration (FAA) kuti igwiritsidwe ntchito pa ndege.
01 Mbiri Yachidule Yachitukuko
Zopangira oxygen zachipatala zidapangidwa kumapeto kwa zaka za m'ma 1970.
Opanga oyambilira anali Union Carbide ndi Bendix Corporation
Poyambirira, iwo amatanthauzidwa ngati makina omwe angalowe m'malo mwa matanki ochuluka a okosijeni ndikupereka gwero losalekeza la mpweya wapanyumba popanda kuyenda pafupipafupi.
Jumao apanganso chitsanzo chonyamula (POC), chomwe tsopano chimapatsa wodwalayo mpweya wofanana ndi 1 mpaka 5 malita pamphindi (LPM: malita pamphindi) malingana ndi kupuma kwa wodwalayo.
Zogulitsa zaposachedwa zimalemera pakati pa 1.3 ndi 4.5 kg, ndipo mosalekeza (CF) zimalemera pakati pa 4.5 ndi 9.0 kg.
02 Ntchito zazikulu
Njira yoperekera mpweya: Monga momwe dzinalo likusonyezera, ndi njira yoperekera mpweya kwa odwala
Zopitilira (zopitilira)
Njira yachikhalidwe yoperekera okosijeni ndiyo kuyatsa mpweyawo ndikutulutsa mpweya mosalekeza mosasamala kanthu kuti wodwalayo akupuma kapena kutulutsa mpweya.
Makhalidwe a ma concentrators okosijeni osalekeza:
Kupereka ma concentrators okosijeni mosalekeza kumafuna masieve akuluakulu a ma molekyulu ndi zigawo za kompresa, komanso zida zina zamagetsi. Izi zimawonjezera kukula ndi kulemera kwa chipangizocho ndi pafupifupi 9KG. (Dziwani: Kutumiza kwake kwa okosijeni kuli mu LPM (malita pa mphindi)
Pulse (pakufunika)
Zonyamula mpweya wa okosijeni ndi zosiyana chifukwa zimangopereka mpweya pamene zimazindikira mpweya wa wodwalayo.
Ma pulse oxygen concentrators:
Pulse (yomwe imatchedwanso intermittent flow or on-demand) POCs ndi makina ang'onoang'ono, omwe nthawi zambiri amalemera pafupifupi 2.2 kg.
Chifukwa ndi ang'onoang'ono komanso opepuka, odwala sangawononge mphamvu zomwe amapeza kuchokera kumankhwala ponyamula.
Kuthekera kwawo kusunga okosijeni ndikofunikira kuti chipangizocho chizikhala cholimba popanda kuwononga nthawi yopereka okosijeni.
Makina ambiri amakono a POC amapereka okosijeni mu njira yoperekera (pofuna) ndipo amagwiritsidwa ntchito ndi cannula yamphuno kuti apereke mpweya kwa wodwalayo.
Zachidziwikire, palinso ma concentrators ena okosijeni omwe ali ndi njira zonse zogwirira ntchito.
Zigawo zazikulu ndi mfundo:
Mfundo yogwiritsira ntchito POC ndi yofanana ndi ya ma concentrators a oxygen kunyumba, omwe amagwiritsa ntchito teknoloji ya PSA pressure swing adsorption.
Zigawo zazikuluzikulu ndi ma compressor ang'onoang'ono a mpweya / matanki a sieve / matanki osungira okosijeni ndi ma valve solenoid ndi mapaipi.
Kayendedwe kantchito: Kuzungulira kumodzi, kompresa yamkati imakakamira mpweya kudzera mu sefa yama cell
Zosefera zimapangidwa ndi tinthu tating'ono ta silicate za zeolite, zomwe zimatha kutsitsa mamolekyu a nayitrogeni.
Mumlengalenga muli pafupifupi 21% mpweya ndi 78% nayitrogeni; ndi 1% zosakaniza zina za gasi
Choncho kusefa ndi kulekanitsa nayitrogeni ku mpweya ndi kuika mpweya.
Pamene chiyero chofunikira chikufikira ndipo kukakamizidwa kwa thanki yoyamba ya molekyulu kumafika pafupifupi 139Kpa.
Oxygen ndi mpweya wina wochepa umatulutsidwa mu thanki yosungiramo mpweya
Mphamvu ya silinda yoyamba ikatsika, nayitrogeni imatulutsidwa
Valavu imatsekedwa ndipo mpweya umatulutsidwa mumlengalenga wozungulira.
Mpweya wambiri wopangidwa umaperekedwa kwa wodwalayo, ndipo gawo lina limatumizidwanso pazenera.
Kutulutsa zotsalira zomwe zatsala mu nayitrogeni ndikukonzekeretsa zeolite kwa kuzungulira kotsatira.
Dongosolo la POC limagwira ntchito ngati scrubber ya nayitrogeni yomwe imatha kutulutsa mpweya wopitilira 90% wamankhwala.
Zizindikiro zazikulu zogwirira ntchito:
Kodi ingapereke zowonjezera zowonjezera okosijeni molingana ndi kayendedwe ka mpweya wa wodwalayo panthawi yomwe imagwira ntchito bwino? Kuchepetsa kuwonongeka kwa hypoxia m'thupi la munthu.
Kodi ingapereke ndende yokhazikika ya okosijeni ndikusunga zida zothamanga kwambiri?
Kodi zingatsimikize kuyenda kwa okosijeni wofunikira pakugwiritsa ntchito tsiku ndi tsiku?
Kodi ingakutsimikizireni kuchuluka kwa batire (kapena mabatire angapo) ndi zida zamagetsi zamagetsi zopangira nyumba kapena galimoto?
03 Zogwiritsa
Medical Imalola odwala kugwiritsa ntchito okosijeni 24/7,
kuchepetsa chiwopsezo cha kufa ndi nthawi pafupifupi 1.94 poyerekeza ndi kugwiritsa ntchito usiku wonse.
Zimathandizira kupirira zolimbitsa thupi polola ogwiritsa ntchito kuchita masewera olimbitsa thupi nthawi yayitali.
Imathandiza kuonjezera kupirira pazochitika za tsiku ndi tsiku.
Poyerekeza ndi kunyamula thanki ya oxygen,
POC ndi chisankho chotetezeka chifukwa imatha kupereka mpweya wabwino pakufunika.
Zipangizo za POC nthawi zonse zimakhala zazing'ono komanso zopepuka kuposa makina a canister ndipo zimatha kupereka mpweya wautali.

04 Kugwiritsa ntchito ndege
Chivomerezo cha FAA
Pa May 13, 2009, Dipatimenti Yoona za Maulendo ku United States (DOT) inagamulapo lamuloli
kuti zonyamula ndege zonyamula anthu okhala ndi mipando yopitilira 19 ziyenera kulola okwera omwe akuzifuna kugwiritsa ntchito ma POC ovomerezedwa ndi FAA.
Lamulo la DOT lavomerezedwa ndi ndege zambiri zapadziko lonse lapansi
05 Kugwiritsa ntchito usiku
Odwala omwe ali ndi oxygen desaturation chifukwa cha kukomoka kwa kugona sakulimbikitsidwa kugwiritsa ntchito mankhwalawa, ndipo makina a CPAP nthawi zambiri amalimbikitsidwa.
Kwa odwala omwe ali ndi vuto la kupuma chifukwa cha kupuma mozama, kugwiritsa ntchito POCs usiku ndi mankhwala othandiza.
Makamaka pakubwera ma alarm ndi teknoloji yomwe imatha kuzindikira pamene wodwala akupuma pang'onopang'ono panthawi ya tulo ndikusintha kuthamanga kapena bolus voliyumu moyenerera.
