Nekuderedzwa kwemitemo yekudzora, huwandu hwevanhu vane COVID-19 hwawedzera zvakanyanya. Kunyangwe hutachiona hwacho husina kupararira zvakanyanya, kuchine njodzi yekuoma kwechipfuva, kushaya mweya, uye kutadza kufema zvakanaka kune vakwegura neavo vane zvirwere zvakakomba. National Health Commission yakasimbisa mumusangano nevatori venhau kuti, "Kurapwa kweCOVID-19 kunofanirwa kuve kwakanyatsogadzirwa, kunyanya kune vakwegura vane zvirwere zvishoma izvo zvinofanira kubatsirwa nekukurumidza kudzivirira kuipa kwechirwere chavo, kusanganisira kurapwa kwakazara kwakadai sekurapa mavairasi, oxygen therapy, uye mishonga yechivanhu yeChinese."

Kurapa neokisijeni inzira inoshanda panguva yakakodzera inoderedza kusagadzikana kunokonzerwa nekushaya hope. Dunhu reKangbashiqiao muInner Mongolia rakapa majenareta eokisijeni kana zvimwe zvishandiso zveokisijeni zvinotakurika kuvanhu vakavharirwa mudzimba kuburikidza nenharaunda dzemumigwagwa, zvichiita kuti zvive nyore kuti vagamuchire oxygen therapy kumba. Mumamiriro ezvinhu aripo, mhuri dzakajairika dzinofanira kuzvigadzirira majenareta eokisijeni here? Beoka, ane ruzivo rwemakore anopfuura makumi maviri mubasa rekuvandudza, achapindura mibvunzo yako.

Kupatsanurwa kwevanogadzira okisijeni yemumba
Magadzirirwo eokisijeni anonyanya kushandiswa mudzimba akavakirwa pamagadzirirwo eokisijeni emolecular see, ayo anoshandisa masefa emolecular seabsorbents. Kuburikidza nekufamba kwemhepo kwe pressurized adsorption uye depressurized analysis, okisijeni inoparadzaniswa uye inobviswa mumhepo nenzira ine hutano uye isingakuvadzi, uye okisijeni yakawanda inobuda.

Zvichienderana nerudzi rwekupihwa kweokisijeni, majenareta eokisijeni emolecular sieve anogona kukamurwa kuita kupihwa kweokisijeni inoenderera mberi uye kupihwa kweokisijeni inotenderera. Yekutanga inogona kushandiswa chete kana yakavharwa kumba. Jenareta yeokisijeni inoramba ichiburitsa okisijeni, asi mwero wekushandiswa kweokisijeni wakaderera, uye kushandiswa kwenguva refu kunogona kutungamira mumhino dzakaoma. Kupihwa kweokisijeni inotenderera kunoshandisa sensor yekufema ine hunhu hwepamusoro kuti ipe okisijeni kana mushandisi apinza mweya, uye inomira kupa okisijeni kana mushandisi aburitsa mweya. Mwero wekushandiswa kweokisijeni wakakwira, uye kubuda kwayo kwakadzikama uye kunoshanda.

Mitemo yehunyanzvi yemagetsi ekugadzira okisijeni mudzimba

Mwero wekuyerera kweokisijeni
Mwero wekuyerera kweokisijeni unoreva mwero wekubuda kweokisijeni paminiti kubva kujenareta yeokisijeni. Kune majenareta eokisijeni anoenderera mberi, majenareta e1L, 3L, uye 5L akajairika. Jenareta ye5L zvinoreva kuti kuburitswa kweokisijeni paminiti i5 litres. Zvisinei, kutaura chokwadi, okisijeni inogadzirwa nejenareta yeokisijeni inorasika kana mushandisi achifema. Kusiyana neizvi, jenareta yeokisijeni inongopa okisijeni chete kana mushandisi achifema. Semuenzaniso, jenareta yeokisijeni inotenderera ine simba re0.8L/min yakaenzana nejenareta yeokisijeni inoenderera mberi inoburitsa marita matatu kusvika mashanu paminiti.

Kuwanda kweokisijeni
Kuwanda kweokisijeni ndiko huwandu hweokisijeni mumhepo inobuda mugetsi rinogadzira okisijeni. Pakusarudza muchina weokisijeni, zvakakosha kutarisisa huwandu hweokisijeni pahuwandu hwepamusoro hwemhepo inoyerera. Zvinokurudzirwa kushandisa muchina weokisijeni une huwandu hweokisijeni hunogara huripo hunopfuura 90%.

Zvishandiso zvepakati zvemajenareta eokisijeni emumba
Zvikamu zvikuru zvemuchina wekugadzira okisijeni wemolecular seeve ndiwo molecular seeve necompressor. Zvishandiso zvepakati zvinovimbika zvinogona kuona kuti muchina wekugadzira okisijeni unoshanda zvakanaka kwenguva yakareba, uye unodzikamisa huwandu hweokisijeni inobuda kwenguva yakareba. Inofanira kunge iine simba rakasimba uye ichigadzira kupisa kushoma nehupenyu hwakareba hwekushanda.

Pamusoro pezvinhu zvataurwa pamusoro apa, pakusarudza jenareta reokisijeni rekuchengetedza, vanhu vanofanirawo kutarisisa kuti rinoita sei, sevhisi yekutengeswa mushure mekutengesa, uye kuti rakareruka here uye rinotakurika, haritore nzvimbo, uye rinogona kushandiswa munzvimbo dzakasiyana siyana dzakadai sekunze, parwendo rwebhizinesi, kana parwendo. Majenareta eokisijeni echinyakare anowanzo kuve akakura uye haakwanise kutakurwa. Zvisinei, nekukura nekukurumidza kwetekinoroji,Jenareta yeokisijeni inotakurika yaBeokaKuhutano, saizi yemuchina wekugadzira okisijeni we5L wekare ndeye 5%, iyo iri diki uye inotakurika. Inoshandisa ma "molecular seeves" anobva kuFrance uye ma "miniature compressors" anoshanda zvakanyanya, ine "pulse output" yakaenzana ne3-5L, uye ine "constant oxygen concentration" ye93%±3% mumhando shanu.

Jenareta yeokisijeni inotakurika yaBeokaKuchengetedza hutano kwakakura semuchindwe, kunogona kutakurwa neruoko rumwe, fudzi rakasungirirwa, kana fudzi rakasungirirwa kaviri, uye kunogona kushandiswa pakufamba netsoka nekufamba munzvimbo dzakakwirira kusvika pamamita 5000, pamwe chete nevanhu vakwegura vari kumba kana kubuda. Nemuchina uyu wekugadzira okisijeni, vakwegura havachafaniri kugara mumba zuva rese uye vanogona kufamba-famba nevana vavo nevazukuru, vachinakidzwa nehupenyu hunofadza uye hwemhando yepamusoro pavanenge vakwegura.
