Idivayisi esetshenziselwa ukuhlinzeka ngokwelashwa komoyampilo okungahlinzeka ngokuqhubekayo ukugcwala komoyampilo okungaphezu kuka-90% ngenani lokugeleza elilingana no-1 kuya ku-5 L/min.
Ifana ne-cocentrator ye-oxygen yasekhaya (OC), kodwa encane futhi ehamba phambili. Futhi ngenxa yokuthi incane ngokwanele/iyaphatheka, izinhlobo eziningi manje sezigunyazwe yi-Federal Aviation Administration (FAA) ukuze zisetshenziswe ezindizeni.
01 Umlando Omfishane Wentuthuko
Ama-concentrator komoyampilo wezokwelapha athuthukiswa ngasekupheleni kwawo-1970.
Abakhiqizi bokuqala bahlanganisa i-Union Carbide ne-Bendix Corporation
Ekuqaleni, bachazwa njengomshini ongashintsha amathangi e-oksijini amakhulu futhi unikeze umthombo oqhubekayo womoya-mpilo wasekhaya ngaphandle kokuhamba njalo.
U-Jumao uphinde wasungula imodeli ephathekayo (i-POC), manje enikeza isiguli umoya-mpilo olingana namalitha angu-1 kuya kwangu-5 ngomzuzu (LPM: amalitha ngomzuzu) kuye ngezinga lokuphefumula lesiguli.
Imikhiqizo yakamuva ye-pulsed inesisindo esiphakathi kuka-1.3 no-4.5 kg, kanti i-continuous (CF) inesisindo esiphakathi kuka-4.5 no-9.0 kg.
02 Imisebenzi esemqoka
Indlela yokukhipha umoya-mpilo: Njengoba igama lisho, kuyindlela yokuletha umoya-mpilo ezigulini
Okuqhubekayo (okuqhubekayo)
Indlela evamile yokuhlinzeka komoyampilo iwukuvula umoya-mpilo futhi ukhiphe umoya-mpilo ngokuqhubekayo kungakhathaliseki ukuthi isiguli siyahogela noma siyawukhipha yini.
Izici ze-oxygen concentrators eqhubekayo:
Ukuhlinzeka ngokugxila kwe-oksijeni okuqhubekayo kudinga ama-sieve amangqamuzana amakhulu kanye nezingxenye ze-compressor, kanye nezinye izinto zokusebenza ze-elekthronikhi. Lokhu kwandisa usayizi nesisindo sedivayisi cishe ngo-9KG. (Qaphela: Ukulethwa komoyampilo wayo ku-LPM (amalitha ngomzuzu))
I-Pulse (ifuneka kakhulu)
Ama-concentrator komoyampilo aphathwayo ahlukile ngoba anikeza umoya-mpilo kuphela lapho ethola ukuhogela kwesiguli.
Izici ze-pulse oxygen concentrators:
I-Pulse (ebuye ibizwe ngokuthi ukugeleza okuphakathi noma okufunwa kakhulu) Ama-POC ayimishini emincane kakhulu, ngokuvamile enesisindo esingu-2.2 kg.
Ngenxa yokuthi mancane futhi alula, iziguli ngeke ziwachithe amandla atholakala ekwelashweni ngokuwuthwala.
Ikhono labo lokulondoloza umoya-mpilo liyisihluthulelo sokugcina idivayisi ihlangene ngaphandle kokudela isikhathi sokunikezwa komoyampilo.
Izinhlelo eziningi zamanje ze-POC zinikeza umoya-mpilo kumodi yokulethwa kwe-pulsed (on-demand) futhi asetshenziswa ne-cannula yamakhala ukuletha umoya-mpilo esigulini.
Vele, akhona futhi amanye ama-oxygen concentrator anazo zombili izindlela zokusebenza.
Izingxenye nezimiso eziyinhloko:
Umgomo wokusebenza we-POC uyafana naleyo yezigxivizo komoyampilo wasekhaya, zombili ezisebenzisa ubuchwepheshe be-PSA be-press swing adsorption.
Izingxenye eziyinhloko ama-compressor komoya amancane/ amathangi esisefo se-molecular/ amathangi okugcina umoya-mpilo namavalvu e-solenoid namapayipi.
Ukugeleza komsebenzi: Umjikelezo owodwa, i-compressor yangaphakathi icindezela umoya ngohlelo lwesihlungi se-molecular sieve
Isihlungi sakhiwe izinhlayiya ze-silicate ze-zeolite, ezingakha ama-molecule e-nitrogen.
Umkhathi uqukethe cishe u-21% we-oxygen kanye nama-78% we-nitrogen; kanye no-1% wezinye izingxube zegesi
Ngakho inqubo yokuhlunga iwukuhlukanisa i-nitrogen emoyeni futhi kugxiliswe umoya-mpilo.
Lapho ubumsulwa obudingekayo bufinyelelwa futhi ukucindezela kwethangi le-molecular sieve yokuqala kufinyelela cishe ku-139Kpa.
Umoya-mpilo kanye nenani elincane lamanye amagesi kukhishwa ethangini lokugcina umoya-mpilo
Lapho ukucindezela kusilinda sokuqala kwehla, i-nitrogen iyakhululwa
I-valve ivaliwe futhi igesi ikhishelwa emoyeni ozungezile.
Iningi lomoya-mpilo okhiqizwayo lilethwa esigulini, futhi ingxenye ibuyiselwa esikrinini.
Ukuze ukhiphe insalela esele ku-nitrogen bese ulungiselela i-zeolite yomjikelezo olandelayo.
Uhlelo lwe-POC lusebenza njengesihluzi se-nitrogen esingahlala sikhiqiza umoya-mpilo ofinyelela ku-90% webanga lezokwelapha.
Izinkomba zokusebenza ezibalulekile:
Ingabe inganikeza isithasiselo somoya-mpilo esanele ngokomjikelezo wokuphefumula kwesiguli phakathi nokusebenza kwaso okuvamile? Ukunciphisa ukulimala kwe-hypoxia emzimbeni womuntu.
Ingabe inganikeza ukugxiliswa komoyampilo okujwayelekile kuyilapho igcina igiya lokugeleza eliphezulu?
Ingabe ingaqinisekisa ukugeleza komoyampilo odingekayo ukuze usetshenziswe nsuku zonke?
Ingabe ingaqinisekisa umthamo owanele webhethri (noma amabhethri amaningi) kanye nezinsiza zokushaja izintambo zamandla okusetshenziswa ekhaya noma kwemoto?
03 Sebenzisa
Medical Ivumela iziguli ukuthi zisebenzise i-oxygen therapy 24/7,
ukunciphisa izinga lokufa izikhathi ezingaba ngu-1.94 uma kuqhathaniswa nokusetshenziswa ebusuku kuphela.
Isiza ukuthuthukisa ukukhuthazela kokuzivocavoca ngokuvumela abasebenzisi ukuthi bazivocavoce isikhathi eside.
Isiza ukwandisa ukukhuthazela emisebenzini yansuku zonke.
Uma kuqhathaniswa nokuthwala ithangi le-oxygen,
I-POC iyinketho ephephile ngoba inganikeza igesi ehlanzekile uma idingeka.
Amadivayisi e-POC ahlala emancane futhi elula kunezinhlelo ze-canister futhi anganikeza ukuhlinzekwa komoya okude.

Ukunakekelwa kwesikhumba
04 Ukusetshenziswa kwendiza
Ukugunyazwa kwe-FAA
Ngo-May 13, 2009, uMnyango Wezokuthutha wase-US (DOT) wakhipha isinqumo
ukuthi izinkampani zezindiza ezisebenzisa izindiza zabagibeli ezinezihlalo ezingaphezu kuka-19 kufanele zivumele abagibeli abazidingayo ukuthi basebenzise ama-POC agunyazwe yi-FAA.
Umthetho we-DOT wamukelwe izindiza eziningi zamazwe ngamazwe
05 Ukusetshenziswa kwasebusuku
Iziguli ezinokuphelelwa umoya komoyampilo ngenxa ye-apnea yokulala azinconywa ukuthi zisebenzise lo mkhiqizo, futhi imishini ye-CPAP ngokuvamile iyanconywa.
Ezigulini ezinokuphelelwa umoya ngenxa yokuphefumula okungajulile, ukusebenzisa ama-POC ebusuku kuwukwelapha okuwusizo.
Ikakhulukazi ngokufika kwama-alamu nobuchwepheshe obukwazi ukubona lapho isiguli siphefumula kancane ngesikhathi sokulala futhi silungise ukugeleza noma ivolumu ye-bolus ngokufanele.
