Isixhobo esisetyenziselwa ukubonelela unyango lwe-oxygen olunokuthi lunikeze ngokuqhubekayo i-oxygen concentration ye-oxygen engaphezu kwe-90% kwinqanaba lokuhamba elilingana ne-1 ukuya kwi-5 L / min.
Ifana ne-oxygen concentrator yasekhaya (OC), kodwa encinci kunye neselula. Kwaye ngenxa yokuba incinci ngokwaneleyo / iyaphatheka, uninzi lweempawu ngoku ziqinisekisiwe yiFederal Aviation Administration (FAA) ukuze zisetyenziswe kwinqwelomoya.
01 Imbali emfutshane yoPhuhliso
Iiconcentrators zeoksijini yezonyango zaphuhliswa ekupheleni kweminyaka yoo-1970.
Abavelisi bokuqala baquka i-Union Carbide kunye ne-Bendix Corporation
Ekuqaleni, bachazwa njengomatshini onokuthatha indawo yeitanki ze-oksijini eninzi kwaye unikeze umthombo oqhubekayo we-oksijini yasekhaya ngaphandle kokuhamba rhoqo.
U-Jumao uye wavelisa imodeli ephathekayo (i-POC), ngoku inika isigulane i-oksijini elingana ne-1 ukuya kwi-5 ilitha ngomzuzu (LPM: iilitha ngomzuzu) kuxhomekeke kwisantya sokuphefumula kwesigulane.
Iimveliso zepulsed zamva nje zinobunzima phakathi kwe-1.3 kunye ne-4.5 kg, kwaye i-continuous (CF) inobunzima phakathi kwe-4.5 kunye ne-9.0 kg.
02 Imisebenzi ephambili
Indlela yokubonelela ngeoksijini: Njengoko igama lithetha, yindlela yokuhambisa i-oksijini kwizigulane
Iyaqhubeka (iyaqhubeka)
Indlela yendabuko yokubonelela nge-oksijeni kukuguqula i-oksijini kwaye ikhuphe i-oksijini ngokuqhubekayo kungakhathaliseki ukuba isigulane siyayikhupha okanye ikhuphe.
Iimpawu ze-oxygen concentrators eziqhubekayo:
Ukubonelela ngokuqhubekayo i-oxygen concentrators kufuna iisefu ezinkulu ze-molecular kunye ne-compressor components, kunye nezinye izixhobo ze-elektroniki. Oku kwandisa ubungakanani kunye nobunzima besixhobo malunga ne-9KG. (Qaphela: Ukuhanjiswa kweoksijini kukwi-LPM (ilitha ngomzuzu))
I-Pulse (kwimfuno)
I-oxygen concentrators ephathekayo yahlukile kuba inika i-oksijini kuphela xa ibona i-inhalation yesigulane.
Iimpawu ze-pulse oxygen concentrators:
I-Pulse (ekwabizwa ngokuba yi-intermittent flow or on-demand) Ii-POC zezona matshini zincinci, zihlala zinobunzima obumalunga ne-2.2 kg.
Ngenxa yokuba zincinci kwaye zilula, izigulane aziyi kuchitha amandla afunyenwe kunyango ngokuwuthwala.
Ukukwazi kwabo ukugcina ioksijini ngundoqo ekugcineni isixhobo sibambene ngaphandle kokuncama ixesha lokubonelela ngeoksijini.
Uninzi lweenkqubo ze-POC zangoku zibonelela nge-oksijini kwimodi yokuhambisa i-pulsed (on-demand) kwaye isetyenziswe nge-cannula ye-nasal ukuhambisa i-oksijini kwisigulane.
Ewe kunjalo, kukwakho nezinye izigxina zeoksijini ezineendlela zombini zokusebenza.
Amacandelo kunye nemithetho-siseko:
Umgaqo wokusebenza we-POC uyafana naleyo ye-oxygen concentrators yasekhaya, zombini zisebenzisa i-PSA pressure swing adsorption technology.
Amacandelo aphambili ziicompressors zomoya ezincinci/iitanki zesihluzo semolekyuli/iitanki zokugcina ioksijini kunye neevalvu zesolenoid kunye nemibhobho.
Ukuhamba komsebenzi: Umjikelo omnye, icompressor yangaphakathi icinezela umoya ngenkqubo yokucoca i-molecular sieve
Isihluzo senziwe ngamasuntswana e-silicate e-zeolite, anokuthi adsorbe iimolekyuli zenitrogen.
I-atmosfera iqulethe malunga ne-21% ye-oxygen kunye ne-78% ye-nitrogen; kunye ne-1% neminye imixube yerhasi
Ngoko inkqubo yokuhluza kukwahlula initrogen emoyeni ize igxininise ioksijini.
Xa ubunyulu obufunekayo bufikelelwe kwaye uxinzelelo lwetanki yokuqala ye-molecular sieve ifikelela malunga ne-139Kpa.
Ioksijeni kunye nenani elincinci lezinye iigesi zikhutshwa kwitanki yokugcina i-oxygen
Xa uxinzelelo lwehla kwi-cylinder yokuqala, i-nitrogen iyakhululwa
Ivalve ivaliwe kwaye igesi ikhutshwe emoyeni ojikelezayo.
Uninzi lweoksijini eveliswayo ihanjiswa kwisigulane, kwaye inxalenye ibuyiselwa kwisikrini.
Ukugungxula intsalela eshiywe kwinitrogen kwaye ulungiselele i-zeolite kumjikelo olandelayo.
Inkqubo ye-POC isebenzayo i-nitrogen scrubber ekwazi ukuvelisa ngokuqhubekayo ukuya kwi-90% ye-oxygen ye-medical-grade.
Iimpawu eziphambili zokusebenza:
Ngaba inokubonelela ngenkxaso yeoksijini eyaneleyo ngokomjikelezo wokuphefumla kwesigulana ngexesha lokusebenza kwayo okuqhelekileyo? Ukunciphisa ingozi ye-hypoxia kumzimba womntu.
Ngaba inokubonelela ngoxinaniso lweoksijini esemgangathweni ngelixa igcina ezona zixhobo zihamba phambili?
Ngaba inokuqinisekisa ukuhamba kweoksijini efunekayo kusetyenziso lwemihla ngemihla?
Ngaba inokuqinisekisa umthamo owaneleyo webhetri (okanye iibhetri ezininzi) kunye nokutshaja izincedisi zentambo zamandla kusetyenziso lwasekhaya okanye lwemoto?
03 Ukusetyenziswa
Unyango luvumela izigulane ukuba zisebenzise unyango lwe-oxygen 24/7,
ukunciphisa izinga lokufa malunga namaxesha angama-1.94 xa kuthelekiswa nokusetyenziswa ebusuku kuphela.
Inceda ukuphucula ukunyamezela komthambo ngokuvumela abasebenzisi ukuba benze umthambo ixesha elide.
Inceda ukwandisa ukunyamezela kwimisebenzi yemihla ngemihla.
Xa kuthelekiswa nokuthwala itanki yeoksijini,
I-POC lukhetho olukhuselekileyo kuba inokubonelela ngerhasi esulungekileyo xa ifunwa.
Izixhobo ze-POC zihlala zincinci kwaye zikhaphukhaphu kuneenkqubo ze-canister kwaye zinokubonelela ngonikezelo olude lwe-oxygen.

04 Ukusetyenziswa kweenqwelomoya
Imvume yeFAA
NgoMeyi 13, 2009, iSebe Lezothutho laseUnited States (DOT) lawisa isigwebo
ukuba abathwali bomoya abasebenzisa iinqwelomoya zabakhweli ezinezihlalo ezingaphezu kwe-19 kufuneka bavumele abakhweli abazifunayo ukuba basebenzise ii-POC ezivunywe yi-FAA.
Umgaqo we-DOT wamkelwe ziinqwelomoya ezininzi zamazwe ngamazwe
05 Ukusetyenziswa kwasebusuku
Izigulane ezine-oxygen desaturation ngenxa ye-apnea yokulala ayikhuthazwa ukuba isebenzise le mveliso, kwaye oomatshini be-CPAP badla ngokucetyiswa.
Kwizigulana ezinokuphelelwa ngamandla ngenxa yokuphefumla nzulu, ukusetyenziswa ebusuku kwee-POCs lunyango oluluncedo.
Ngokukodwa ngokufika kwee-alamu kunye nobuchwepheshe obunokubona xa isigulane siphefumula ngokukhawuleza ngexesha lokulala kwaye silungise ukuhamba okanye ivolumu ye-bolus ngokufanelekileyo.
