Standard For Medical Oxygen Concentrators

Oxygen purity: Cov pa oxygen uas tsim los ntawm kev kho mob oxygen concentrators yuav tsum ua tau raws li cov kev cai rau kev kho mob oxygen teev nyob rau hauv GB 8982-2009, thiab cov pa concentration yuav tsum siab tshaj los yog sib npaug rau 90% (V/V). Qhov no txhais tau hais tias nyob rau hauv cov xwm txheej ntawm qhov siab tshaj plaws ntawm 5L / min, cov pa oxygen concentration yuav tsum ncav cuag tus qauv no tom qab 30 feeb ntawm kev pib. 1
Airtightness ntawm pneumatic system: Tag nrho cov fasteners yuav tsum ruaj ntseg txuas yam tsis muaj looseness, thiab ntau cov kav dej thiab cov kav dej yuav tsum tau npaj kom zoo, tsis muaj cua nkag ntawm lawv cov kev sib txuas.
Kev txwv tsis pub muaj suab nrov: Cov suab nrov ntawm kev kho mob oxygen concentrators yuav tsum tsawg dua lossis sib npaug li 60dB (A) kom ntseeg tau tias muaj kev ntsiag to thaum siv.
Flow regulation: Flow regulation yuav tsum tsis tu ncua adjustable nyob rau hauv lub rated flow range, nrog ib tug kam rau siab ntawm ± 10%, kom tau raws li cov kev xav tau ntawm cov neeg siv sib txawv.
Kev nyab xeeb kev ua tau zoo: Kev nyab xeeb ntawm kev kho mob oxygen concentrators yuav tsum ua raws li cov cai ntawm GB9706.1-2007, YY0732-2009, thiab YY0709-2009 kom muaj kev nyab xeeb thaum siv.
