Chishandiso chinoshandiswa kupa okisijeni therapy iyo inogona kuramba ichipa iyo oxygen concentration inopfuura 90% pachiyero chekuyerera chakaenzana ne1 kusvika 5 L/min.
Iyo yakafanana neyeimba okisijeni concentrator (OC), asi idiki uye yakawanda mobile. Uye nekuti idiki zvakakwana / inotakurika, mhando zhinji dzave kubvumidzwa neFederal Aviation Administration (FAA) kuti ishandiswe mundege.
01 Pfupi Nhoroondo Yebudiriro
Medical oxygen concentrators yakagadzirwa mukupera kwema1970.
Vagadziri vekutanga vaisanganisira Union Carbide uye Bendix Corporation
Pakutanga, vakatsanangurwa semuchina unogona kutsiva matangi eokisijeni akawanda uye kupa chitubu cheokisijeni yepamba pasina nguva zhinji yekufambisa.
Jumao akagadzirawo modhi inotakurika (POC), iyo zvino inopa murwere oxygen yakaenzana ne1 kusvika ku5 litres paminiti (LPM: marita paminiti) zvichienderana nekufema kwemurwere.
Zvigadzirwa zvemazuva ano zvepulsed zvinorema pakati pe1.3 ne4.5 kg, uye inoenderera (CF) inorema pakati pe4.5 ne9.0 kg.
02 Mabasa makuru
Oxygen supply method: Sezvinoreva zita, inzira yekuendesa okisijeni kuvarwere
Inoenderera (inoenderera)
Iyo yechinyakare nzira yekupa okisijeni ndeyekubatidza iyo okisijeni uye inoramba ichiburitsa okisijeni zvisinei nekuti murwere anofema kana kuburitsa.
Zvimiro zvekuenderera okisijeni concentrators:
Kupa anoenderera okisijeni concentrators kunoda akakura masieve mamorekuru uye compressor zvikamu, pamwe nemimwe michina yemagetsi. Izvi zvinowedzera saizi uye huremu hwechishandiso neinenge 9KG. (Cherechedza: Kuburitsa kwayo okisijeni kuri muLPM (marita paminiti)
Pulse (pane-inoda)
Anotakurika okisijeni concentrators akasiyana pakuti anongopa okisijeni kana yaona kufema kwemurwere.
Zvimiro zvepulse oxygen concentrators:
Pulse (inonziwo intermittent flow or on-demand) maPOC ndiwo makina madiki, anowanzo kurema 2.2 kg.
Nemhaka yekuti idiki uye yakareruka, varwere havazotambisi simba rinowanikwa kubva mukurapwa nekuritakura.
Kugona kwavo kuchengetedza okisijeni kwakakosha kuchengetedza mudziyo compact pasina kupa nguva yekupa oxygen.
Mazhinji emazuva ano maPOC masisitimu anopa okisijeni mune inopuruzirwa (pa-inoda) nzira yekuendesa uye inoshandiswa nemhino cannula kuendesa oksijeni kumurwere.
Ehe, kune zvakare mamwe maokisijeni concentrators ane ese ari maviri maitiro ekushandisa.
Zvikamu zvikuru uye nheyo:
Iyo inoshanda sisitimu yePOC yakafanana neyeiyo yemba yeokisijeni concentrators, ese anoshandisa PSA pressure swing adsorption tekinoroji.
Zvikamu zvikuru madiki emhepo compressors / molecular sieve matangi / okisijeni ekuchengetedza matangi uye solenoid mavharuvhu uye mapaipi.
Kuyerera kwekushanda: Kutenderera kumwechete, iyo yemukati compressor inomanikidza mweya kuburikidza ne molecular sieve filter system
Iyo sefa inoumbwa ne silicate zvimedu zve zeolite, izvo zvinogona adsorb nitrogen mamorekuru.
Mhepo ine 21% oksijeni uye 78% nitrogen; uye 1% mamwe gasi musanganiswa
Saka nzira yekusefa ndeyekuparadzanisa nitrogen kubva kumhepo uye kuisa oxygen.
Kana kuchena kunodiwa kwasvika uye kudzvanywa kwekutanga molecular sieve tank kunosvika 139Kpa.
Okisijeni uye shoma shoma yemamwe magasi anoburitswa mutangi rekuchengetedza okisijeni
Apo dzvinyiriro muhumburumbira yokutanga inodonha, nitrogen inosunungurwa
Ivhavha yakavharwa uye gasi rinobudiswa mumhepo yakapoteredza.
Yakawanda yeokisijeni inogadzirwa inounzwa kumurwere, uye chikamu chinodzoserwa kuchiratidziro.
Kuburitsa zvakasara zvakasara munitrogen uye kugadzirira zeolite kutenderera kunotevera.
Iyo POC sisitimu inoshanda senitrogen scrubber iyo inogona kugara ichiburitsa kusvika 90% yekurapa-giredhi okisijeni.
Key performance zviratidzo:
Inogona here kupa yakakwana oxygen yekuwedzera zvinoenderana nekufema kwemurwere panguva yekuvhiya kwayo? Kuderedza kukuvadza kwe hypoxia kumuviri wemunhu.
Inogona here kupa yakajairwa okisijeni kusungirirwa uku uchichengetedza yakanyanya kuyerera giya?
Inogona here kuvimbisa kuyerera kweokisijeni inodiwa pakushandiswa kwemazuva ese?
Inogona here kuvimbisa kukwana kwebhatiri huwandu (kana akawanda mabhatiri) uye kuchaja tambo dzemagetsi zvishandiso zvekushandisa pamba kana mota?
03 Zvishandiso
Medical Inobvumira varwere kushandisa oxygen therapy 24/7,
kuderedza huwandu hwevanhu vanofa nenguva dzinosvika 1.94 zvichienzaniswa nekushandiswa kwehusiku chete.
Inobatsira kuvandudza kurovedza muviri kutsungirira nekubvumira vashandisi kurovedza muviri kwenguva yakareba.
Inobatsira kuwedzera kutsungirira mumabasa ezuva nezuva.
Kuenzaniswa nekutakura tangi yeokisijeni,
POC isarudzo yakachengeteka nekuti inogona kupa rakachena gasi painodiwa.
POC zvishandiso zvinogara zvidiki uye zvakareruka pane canister masisitimu uye zvinogona kupa hurefu hweokisijeni.

04 Kushandiswa kwendege
FAA mvumo
Musi waMay 13, 2009, Dhipatimendi Rezvekutakurwa reUnited States (DOT) rakatonga
kuti vatakuri vendege vanofamba nendege dzine zvigaro zvinopfuura gumi nepfumbamwe vanofanira kubvumira vafambi vanodzida kushandisa maPOC akatenderwa neFAA.
Mutemo weDOT wakagamuchirwa nendege dzakawanda dzepasi rose
05 Kushandiswa kwehusiku
Varwere vane oxygen desaturation nekuda kwehope yekurara havakurudzirwe kushandisa chigadzirwa ichi, uye michina yeCPAP inowanzokurudzirwa.
Kune varwere vane desaturation nekuda kwekufema kwakadzika, kushandiswa kwehusiku kwePOCs kurapa kunobatsira.
Kunyanya nekuuya kwemaalarm uye teknolojia inogona kuona kana murwere achifema zvishoma panguva yekurara uye kugadzirisa kuyerera kana bolus volume maererano.
