Ukusetshenziswa kwe-Portable Medical Oxygen Concentrators Ekwelapheni Oksijini Kwasekhaya Kweziguli
Ama-concentrator aphathekayo we-oxygen wezokwelapha asebaluleke kakhulu ekunikezeni ukwelashwa komoyampilo okusekelwe ekhaya ezigulini ezihlushwa izifo eziningi zokuphefumula, okuhlanganisa i-COVID-19, isifo esingamahlalakhona se-pulmonary, i-bronchitis engapheli kanye nenyumoniya.Lawa madivayisi asebenza umsebenzi obalulekile weukuhlinzeka nge-oksijini yezinga lezokwelaphaukunciphisa izinkinga ezihlobene ne-hypoxemia nokuthuthukisa umsebenzi wokuphefumula weziguli.
Ukufeza isidingo seukwelashwa nge-oxygen, ikakhulukazi kuzilungiselelo zasekhaya,ama-concentrators we-oxygen wezokwelapha aphathwayoikakhulukazi sebenzisa ubuchwepheshe be-pressure swing adsorption.Lobu buchwepheshe buncike kuma-adsorbent akhetha i-nitrogen ukuze kukhishwe umoya-mpilo emoyeni osendaweni, okuqinisekisa ukutholakala kwe-umoya-mpilo wokwelapha.Ngokuphawulekayo, i-World Health Organization ibeka ukuthi i-oksijini yezinga lezokwelapha kufanele ibe nokuhlushwa komoyampilo phakathi kuka-90% no-96% V/V, ne-nitrogen eyinsalela ne-argon.Ngokuvumelana nalawa mazinga, ama-concentrator aphathekayo we-oksijeni wezokwelapha asekelwe kwi-adsorption ngokuvamile akhiqiza ukugxila komoyampilo kusuka ku-90% kuya ku-93% ngezinga lokugeleza ngokuvamile elingaphansi kuka-10 L/min.
Ekusebenzeni kwama-concentrators we-oxygen wezokwelapha asuselwa ku-adsorption, i-adsorbent ivuselelwa ngezikhathi ezithile ukuze kugcinwe ukukhiqizwa komoyampilo okusebenzayo.Ukunikezwa komoyampilo okuqhubekayo kwenziwa lula ngamasu anjengokuqoqa umoya-mpilo womkhiqizo kukholamu yokuhlinza bese usakazwa ngesilinganiso esingaguquki ngokuhamba kwesikhathi noma kusetshenziswa imisebenzi enemibhede eminingi.Ukucushwa komjikelezo we-adsorption ye-pressure yohlobo lwe-Skarstrom, okuhlanganisa ukukhiqiza, ukucindezelwa, ukuhlanzwa, kanye nezinyathelo zokucindezela, kuvame ukusetshenziswa kuma-concentrator we-oxygen wezokwelapha aphathwayo.Lawa madivayisi athuthukisa ukuhamba kwamabhayisikili okusheshayo kwamakholomu e-adsorption ukuze kuthuthukiswe ukusetshenziswa kwe-adsorbent kanye nokunciphisa umkhondo wokusebenza.Ngaphezu kwalokho, ukusetshenziswa kosayizi bezinhlayiyana ezincane ze-adsorbent kusiza ukunciphisa ukumelana nokudluliselwa kobuningi futhi kuthuthukise i-adsorption kinetics, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kukonke.
Naphezu kokusebenza ngempumelelo kwezokwelapha eziphathwayo ezivamilei-oxygen concentratoramadizayini, ukucaciswa kwemikhiqizo engaguquki kubangela ukulinganiselwa, ikakhulukazi ekuhlangabezaneni nezidingo ezihlukahlukene ezivela ekushintshashintsheni kwezimo zezokwelapha zeziguli noma amazinga omsebenzi.Ukuze kubhekwane nalesi singqinamba, kunokugxila okukhulayo ekuthuthukiseni ezokwelapha ezithambile ezinombhede owodwaamasistimu we-oxygen concentratorekwazi ukujwayela ukucaciswa kwemikhiqizo ehlukahlukene.Lawa masistimu aguquguqukayo aklanyelwe ukuthuthukisa ukukhiqizwa komoyampilo ngokusebenzisa izinhlaka zokuthuthukisa ezisekelwe ekulingiseni, ikakhulukazi kumongo we-press swing adsorption- kanye nobuchwepheshe obusekelwe ku-pressure vacuum swing adsorption.
Ekuphishekeleni izixazululo eziguquguqukayo ze-oxygen concentrator yezokwelapha, izifundo zokuthuthukisa zenziwe ukuze kuhlolwe ukusebenza kwama-adsorbent ahlukene, okuhlanganisa i-LiX, i-LiLSX, ne-5A zeolite.Phakathi kwalokhu, i-LiLSX iqhamuke njengephambili, ikhombisa izici zokusebenza ezisezingeni eliphakeme.Ngokukhethekile, izinhlelo ze-LiLSX-based flexible vacuum vacuum adsorption adsorption systems zibonise amandla okukhiqiza umoya-mpilo ngamazinga ahlukahlukene okuhlanzeka nokugeleza, kusukela ku-93% kuya ku-95.7% kanye no-1 kuya ku-15 L/min, ngokulandelana.Lokhu okutholakele kugcizelela amandla obuchwepheshe obuphathekayo be-concentrator ye-oxygen yezokwelapha ukuze kuguqulwe izinguqukoukwelashwa kwe-oxygen ekhayangokuvumela ukuzivumelanisa kwesikhathi sangempela nezidingo eziguqukayo zeziguli.
Kafushane, ukusetshenziswa kwama-concentrators we-oksijini wezokwelapha aphathwayo ekwelapheni komoya-mpilo wasekhaya kumelela intuthuko ebalulekile ekunakekelweni kokuphefumula.Ngokusebenzisa izimiso ze-press swing adsorption kanye nokwamukela amasu okuklama avumelana nezimo, lezi zixhobo zimi ngomumo wokuthuthukisa inhlalakahle yesiguli kanye nokwenza lula ukulethwa kokunakekelwa kwezempilo kuzilungiselelo zasekhaya.
