Nkhani - Yoyamba Yonyamula Oxygen Concentrator kumapeto kwa 1970S.

Achotengera oxygen chonyamula(POC) ndi chipangizo chomwe chimagwiritsidwa ntchito popereka chithandizo cha okosijeni kwa anthu omwe amafunikira kuchuluka kwa okosijeni kuposa kuchuluka kwa mpweya wozungulira. Ndizofanana ndi cholumikizira mpweya wa okosijeni (OC), koma ndi yaying'ono kukula kwake komanso mafoni ambiri. Ndizochepa zokwanira kunyamula ndipo ambiri tsopano avomerezedwa ndi FAA kuti agwiritsidwe ntchito pandege.

Zopangira oxygen zachipatala zidapangidwa kumapeto kwa zaka za m'ma 1970. Opanga oyambilira anali Union Carbide ndi Bendix Corporation. Poyamba amaganiziridwa ngati njira yoperekera gwero losalekeza la okosijeni wapanyumba popanda kugwiritsa ntchito akasinja olemera komanso kuperekera pafupipafupi. Kuyambira m'zaka za m'ma 2000, opanga adapanga matembenuzidwe onyamula. Chiyambireni chitukuko chawo choyambirira, kudalirika kwakhala bwino, ndipo POCs tsopano imapanga pakati pa malita imodzi ndi asanu ndi limodzi pamphindi (LPM) ya okosijeni malingana ndi kupuma kwa wodwalayo.Zitsanzo zaposachedwa zakuyenda kwapakatikati kokha zopangidwa zolemera kuchokera ku 2.8 mpaka 9.9 mapaundi (1.3 mpaka 4.5 kg) ndi mayunitsi opitilira (CF) anali pakati pa 10 ndi 20 mapaundi (4.5 mpaka 9.0) kg).

Ndi magawo oyenda mosalekeza, kutumiza kwa okosijeni kumayesedwa mu LPM (malita pamphindi). Kupereka kuyenda kosalekeza kumafuna sieve yokulirapo ya ma molekyulu ndi msonkhano wa pampu/motor, ndi zina zamagetsi. Izi zimakulitsa kukula ndi kulemera kwa chipangizo (pafupifupi 18–20 lbs).

Ndi pakufunika kapena kuthamanga kwa mpweya, kubereka kumayesedwa ndi kukula (mu milliliters) ya "bolus" ya mpweya pa mpweya.

Magawo ena a Portable Oxygen Concentrator amapereka zonse kuyenda mosalekeza komanso mpweya wotuluka.

Zachipatala:

Amalola odwala kugwiritsa ntchito okosijeni 24/7 ndikuchepetsa kufa mochepera 1.94 kuposa kungogwiritsa ntchito usiku wonse.

Kafukufuku waku Canada mu 1999 adatsimikiza kuti kuyika kwa OC motsatira malamulo oyenera kumapereka malo otetezeka, odalirika, okwera mtengo a chipatala choyambirira a oxygen.

Imathandiza kupirira zolimbitsa thupi, polola wogwiritsa ntchito kuchita masewera olimbitsa thupi nthawi yayitali.

Amathandizira kukulitsa mphamvu pazochitika zatsiku ndi tsiku.

POC ndi njira yotetezeka kuposa kunyamula thanki ya okosijeni chifukwa imapanga mpweya wabwino kwambiri pakufunika.

Magawo a POC amakhala ang'onoang'ono komanso opepuka nthawi zonse kuposa ma tanki ndipo amatha kupereka mpweya wautali.

Zamalonda:

Makampani opanga magalasi

Chisamaliro chakhungu

Ndege zopanda mphamvu

Mipiringidzo ya okosijeni ya nightclub ngakhale madokotala ndi FDA awonetsa kukhudzidwa ndi izi.
