01. Isidingo samaconcentrator komoyampilo ngemva kokukhululwa kokuvimbela ubhubhane
I-concentrator ye-oxygen yezokwelapha yasekhaya yasungulwa ekuqaleni kwawo-1970.Ngaphambi kwalokhu, amasilinda e-oksijini anengcindezi ephezulu noma amasistimu oksijini oketshezi oketshezi olusezingeni eliphansi ayedingeka ekwelapheni komoyampilo wezokwelapha ekhaya, okwakudinga ukuthuthwa okuvamile okuvela kubahlinzeki ukuze kwengezelele ukuhlinzekwa komoyampilo wezokwelapha wasekhaya.
Ukuze kulawulwe izindleko, kwavela ama-concentrator komoyampilo e-United States, okwanciphisa kakhulu izithiyo zokuthi abakhiqizi bangene emakethe, futhi ukusungulwa kwezisefo zamangqamuzana ngeminyaka yawo-1950 nakho kwakhuthaza ukuba nokwenzeka kokugxilisa umoya-mpilo ukuze kusetshenziswe ekhaya.Kuze kube ngu-1985, kwaphuma umshini wokuqala wokungenisa umoya-mpilo wasendlini e-United States.
Ubhubhane lomhlaba wonke lwegciwane lomqhele olusha olwaqala ngo-2020, ikakhulukazi ukuqubuka okukhulu eNdiya, senyuse isidingo somhlaba wonke sama-concentrator komoyampilo.Ngesikhathi esifanayo, ama-oximeter angakwazi ukukala ukugcwala kwe-oksijini yegazi esigabeni sokuqala sokwelashwa nawo aheha ukunaka.
Isikhathi sokufika ku-2023, ngokukhululeka kokuvikela nokulawula ubhubhane eChina ekupheleni kuka-2022, ukuvimbela izifo ezinzima nokwelapha iziguli ezigula kakhulu sekuyinto ehamba phambili.
Ngemuva kokutheleleka ngomqhele omusha, uma kunezimpawu ezingakhululekile ezifana ne-dyspnea ne-hypoxemia, ingakhululeka ngokuhogela umoya-mpilo, futhi i-generator ye-oxygen ingasiza iziguli ezihlala zodwa ekhaya, njengabantu asebekhulile abanezifo ezingaphansi.
Ulwazi olufanele lubonisa ukuthi ukusetshenziswa kwe-oxygen concentrators ngabantu abaneminyaka ephakathi kanye nabantu asebekhulile, abesifazane abakhulelwe, iziguli ezikhethekile, njll., Abanamandla avela ku-1L-3L kuya ku-5L-10L.Abantu abanamazinga ahlukahlukene e-hypoxia bangazama ukusebenzisa ama-concentrator komoyampilo ngemva kokubonisana nodokotela.
Umthamo omncane we-1-2L ungowohlobo lokunakekelwa kwezempilo (uhlobo lwasekhaya).Ithuthukisa isimo sokunikezwa komoyampilo emzimbeni, iqede ukukhathala, futhi ibuyisele imisebenzi yomzimba ngokunikezwa komoya-mpilo.Ilungele abanye abantu abaneminyaka ephakathi kanye nabadala, abesifazane abakhulelwe, kanye nabantu abanempilo ebuthakathaka abanezimpawu ze-hypoxia., abasubathi, abasebenza kanzima ngokomzimba nabathengi bengqondo.Ukuze uhambe uye e-Qinghai-Tibet Plateau, amajeneretha omoya-mpilo aphathwayo angakwazi futhi ukukhulula ukungakhululeki okubangelwa ukumelana nokuphakama okuphezulu.
Ngokwezinyathelo Zokulawula Zokubhaliswa Nokufakwa Kwamadivayisi Ezokwelapha ezikhishwe ngo-oda No. 47 Wokulawulwa Kwezwe Lokulawulwa Kwemakethe ngomhla ka-Agasti 26, 2021, kudingeka ngokusobala ukuthi imishini yezokwelapha ye-Class I irekhodwe, kanye nomthamo we-oxygen ongu-1-2L. amajeneretha awe-Class I futhi kufanele aqoshwe.Imishini yezokwelapha ye-Class II, njengama-concentrator komoya-mpilo enamandla angu-3L nangaphezulu, kufanele afake isicelo sesitifiketi sokubhaliswa.
Umthamo omkhulu we-3L nangaphezulu uyibanga lezokwelapha, elikhulula izifo ze-hypoxic acute kanye nezifo zokuphefumula ezingapheli, izifo zenhliziyo nemithambo yegazi kanye nezinye izifo ze-hypoxic ngokunikeza iziguli umoya-mpilo.Kunabathengi abadukisayo emakethe, futhi i-1-2L ichazwa njenge-concentrator ye-oxygen yezokwelapha, edinga ukuthi sigcine amehlo ethu evulekile lapho sithenga.
Ama-concentrators e-oxygen ebangeni lezokwelapha ayingxenye yekilasi lesibili lemishini yezokwelapha enobungozi obulinganiselwe obubalulwe ku-Regulations on the Supervision and Administration of Medical Devices futhi idinga ukulawulwa nokuphathwa okuqinile ukuze kuqinisekiswe ukuphepha nokusebenza kwayo, ezifanele ukukhiqizwa kokunothisa umoya-mpilo. umoya, ukwelashwa komoyampilo noma ukukhululeka kokuphatheka kabi okubangelwa ukuntuleka komoyampilo.
I-oxygen concentrator futhi iyinsiza yokwelapha eshiwo ngokucacile "Kusu Lonke Lokusetshenzwa Kwe-"Class B kanye ne-B Tube" Ye-Novel Coronavirus Infection".
Njengamanje, iningi lamajeneretha komoya-mpilo asendlini emakethe amajeneretha omoya-mpilo we-molecular sieve, abonakala ngezindleko ezishibhile, kulula ukuwasebenzisa, ukunyakaza okuvumelana nezimo, kanye nokuthwala okuphephile.
Isimiso sokusebenza se-molecular sieve oxygen generator ubuchwepheshe be-press swing adsorption (PSA) kanye nobuchwepheshe bokukhipha umoya.Ngesikhathi somsebenzi, i-nitrogen emoyeni iyakhanyiswa bese kuqoqwa umoya-mpilo osele emoyeni, ohlanjululwayo bese uguqulwa ube umoya-mpilo ophezulu, bese kunikezwa umoya-mpilo ezigulini ezinamashubhu oksijini.Yonke inqubo ijikeleziswa ngezikhathi ezithile futhi iguquguqukayo, futhi isisefo se-molecular asidliwe.
Nakuba i-oxygen generator ibizwa ngokuthi "ukukhiqizwa kwe-oxygen", empeleni ayikhiqizi umoya-mpilo, kodwa idlala indima yokukhipha, ukuhlunga, ukuhlanza nokuqoqa umoya-mpilo emoyeni.Amaconcentrator komoya-mpilo nawo awawusizi umzimba womuntu ukuba ubambe umoya-mpilo, okudinga ukuthi iziguli ezithatha umoya-mpilo zibe nekhono lokuphefumula ngokuzenzakalelayo.
Eminyakeni emithathu yalolu bhubhane, siye sahlangana ngokuhlanganyela ukuqhuma nokuphuma esitokweni kusuka kumathemometha asebunzini, ama-thermometers kuye kuma-oximeter, ama-ventilators, amajeneretha omoya-mpilo, njll., kusukela ekutholakaleni okulula kuya ekwelashweni kwe-adjuvant, futhi izindlela zokuphendula sezandile futhi. okuphelele.
Uma kuqhathaniswa nesixwayiso sakuqala se-oximeter, ijeneretha yomoya-mpilo idlala indima ethile yokuvikela abantu abayidinga ngempela.Ngokukhula okusheshayo kwenani labantu abangenwe yileli gciwane, isimo samanje sivivinya ukuzethemba kwabantu ngokushoda kwezinsiza zezokwelapha, kanye ne-concentrator ye-oxygen yasendlini yabantu asebekhulile, iziguli ezinezifo ezingaphansi, abesifazane abakhulelwe, njll. .
