Hauv lub neej niaj hnub no, cov pa oxygen concentrators tau nce zuj zus. Txawm nyob hauv tsev kho mob, tsev, lossis chaw ua kis las,oxygen concentratorsua lub luag haujlwm tseem ceeb: lawv tsis tsuas yog pab cov neeg mob txhim kho txoj kev ua pa, tab sis kuj muab cov pa oxygen rau cov tib neeg xav tau cov pa ntxiv.
Txoj Cai Ua Haujlwm ntawm Oxygen Concentrators
Yog li, cov pa oxygen concentrators ua haujlwm li cas? Cias muab, lawv rho tawm oxygen los ntawm huab cua ambient siv lub cev (thiab qee zaum tshuaj) txoj kev. Lawv cov thev naus laus zis tseem ceeb feem ntau suav nrogkev sib cais membranethiabadsorption sib cais-ob txoj kev siv lub cev siv dav.
Membrane Separation Technology
Membrane sib cais cia siab rau cov khoom siv semipermeable. Thaum huab cua dhau los ntawm daim nyias nyias, oxygen thiab nitrogen raug cais raws li qhov sib txawv ntawm qhov loj me me:
- Oxygen molecules (me me hauv txoj kab uas hla) permeate los ntawm daim nyias nyias;
- Nitrogen molecules (loj nyob rau hauv txoj kab uas hla) yog khaws cia nyob rau sab pub ntawm daim nyias nyias.
- Txoj kev no yog qhov ua tau zoo thiab yooj yim rau kev khiav lag luam, ua rau nws yog thawj thev naus laus zis siv hauvtsev neeg oxygen concentrators.
Cov membrane siv hauv cov txheej txheem no feem ntau yog cov khoom siv polymer (piv txwv li, polyimide) nrog micro- qhov loj me. Cua yog thawj zaug compressed thiab lim kom tshem tawm impurities, ces dhau los ntawm cov membrane module. Kev xaiv permeability ntawm daim nyias nyias yog txiav txim siab los ntawm ob qho tib si molecular loj thiab roj solubility nyob rau hauv cov ntaub ntawv membrane: oxygen muaj ntau dua solubility thiab sai diffusion tus nqi nyob rau hauv lub polymer, yog li nws dhau los ntawm daim nyias nyias sai, ua rau cov pa oxygen -enriched kwj (feem ntau 30-50% oxygen concentration) nyob rau sab permeate.
Adsorption Sib cais Technology
Lwm txoj kev tsim cov pa oxygen ntau yog kev sib cais adsorption (feem ntau yog Pressure Swing Adsorption, PSA).
Hauv cov txheej txheem no:
- Compressed, lim cua yog qhia los ntawm lub txaj ntawm cov khoom tshwj xeeb adsorbent (feem ntau zeolite molecular sieves);
- Lub adsorbent xaiv adsorbs nitrogen (thiab lwm cov kab hluav taws xob) ntawm lub siab tshwj xeeb, thaum cov pa oxygen hla lub txaj;
- Tom qab lub adsorbent tau saturated nrog nitrogen, lub siab yog txo kom desorb nitrogen (regenerating lub adsorbent), thiab lub voj voog rov ua dua.
- Cov khoom kawg ntawm cov txheej txheem no yog concentrated oxygen. Txoj kev no feem ntau yog siv rau hauvloj -scale oxygen concentrators, haum rau cov xwm txheej uas xav tau siab - ntim cov pa oxygen (piv txwv li, tsev kho mob).
Zeolite molecular sieves muaj cov qauv ntxeem tau uas ntxiab nitrogen molecules (vim muaj zog van der Waals rog ntawm nitrogen thiab zeolite nto) thaum tso cai rau oxygen molecules dhau. PSA systems feem ntau siv ob lub txaj adsorbent thaum sib piv: ib lub txaj yog nyob rau theem adsorption (ua pa oxygen), thaum lwm qhov yog nyob rau theem rov tsim dua tshiab (tso tawm adsorbed nitrogen mus rau qhov chaw). Lub voj voog hloov pauv no ua kom muaj cov pa oxygen tsis tu ncua, nrog rau cov pa oxygen ib txwm ncav cuag 90-95% (kev kho mob- qib purity).
Hom Oxygen Concentrators
Oxygen concentrators tuaj nyob rau hauv ntau hom kom tau raws li cov kev xav tau sib txawv:
Portable oxygen concentrators: Tsim los rau ntawm - - mus siv - hnyav thiab nqa tau yooj yim.
Cov pa oxygen hauv tsev: Feem ntau loj dua, tsim rau kev siv txuas ntxiv.
Portable Oxygen Concentrators
Portable oxygen concentrators tau coj kev yooj yim rau ntau tus neeg mob. Txawm hais tias mus ncig lossis koom nrog kev ua si sab nraum zoov, lawv muab cov pa oxygen raws sijhawm, tso cai rau cov neeg siv nyob ntawm nws tus kheej.
Tsev neeg Oxygen Concentrators
Tsev neeg cov pa oxygen concentrators yog tsim los rau cov neeg mob uas xav tau kev kho pa ntev ntev -. Lawv feem ntau muaj peev xwm tso zis ntau dua thiab tuaj yeem ua haujlwm tsis tu ncua 24/7. Rau cov neeg mob nrogChronic obstructive pulmonary disease (COPD), cov cuab yeej no ho txhim kho lawv lub neej zoo.
Daim ntawv thov Scenario ntawm Oxygen Concentrators
Cov pa oxygen concentrators muaj cov ntawv thov dav heev-los ntawm cov tsev kho mob hnyav (ICUs) mus rau cov chav pw hauv tsev, lawv nyob txhua qhov chaw. Thaum muaj kev sib kis, tshwj xeeb,oxygen concentratorstau los ua "cov cuab yeej cawm txoj sia" rau ntau tsev neeg.
Oxygen Concentrators hauv Tsev Kho Mob
Hauv tsev kho mob, cov pa oxygen concentrators muab cov pa oxygen tseem ceeb rau cov neeg mob hnyav. Txawm hais tias ua pa tsis ua haujlwm lossis lwm yam mob uas xav tau kev kho mob oxygen, lawv ua lub luag haujlwm tseem ceeb.
Kev siv tsev
Hauv tsev, cov pa oxygen concentrators pab cov neeg laus thiab cov neeg mob uas muaj mob ntev zoo tswj lawv txoj kev noj qab haus huv. Nrog kev nce qib ntawm kev siv technology, niaj hnuboxygen concentratorsyog cov neeg siv ntau dua - tus phooj ywg thiab yooj yim rau kev khiav lag luam, ua kom yooj yim rau cov neeg siv.
Xaus
Hauv kev xaus, raws li cov cuab yeej kho mob tseem ceeb,oxygen concentratorsembody thev naus laus zis kev nce qib thiab kev saib xyuas tib neeg los ntawm lawv cov qauv kev ua haujlwm thiab kev siv. Txawm hais tias koj xav tau lawv los txhim kho kev noj qab haus huv lossis txhim kho kev yooj yim txhua hnub, nkag siab txog kev ua haujlwm thiab kev ua haujlwm ntawmoxygen concentratorsyog qhov tseem ceeb heev.
