一、醫用制氧機氧氣濃度是多少
《醫用分子篩制氧(yang)(yang)設備通用技術(shu)規范(fan)》:以空(kong)氣為(wei)原料(liao),利用分子篩變(bian)壓吸(xi)附(fu)工藝生產(chan)的氧(yang)(yang)氣。這種(zhong)氧(yang)(yang)氣的氧(yang)(yang)濃度(du)為(wei)90%~96%(V/V),剩(sheng)余的組分主要(yao)是氬和氮。一般來說(shuo),會規定醫用氧(yang)(yang)氣必須達到93%才算標準,才能在臨床(chuang)救治中投入(ru)使(shi)用。
二、家用制氧機氧氣濃度是多少
家用制氧(yang)機(ji)氧(yang)氣濃(nong)度跨度范圍(wei)較(jiao)大,一般(ban)是在(zai)30%~90%±3%這個(ge)范圍(wei)中。與平均氧(yang)氣濃(nong)度約35%一樣,它適合上班(ban)族和(he)學生。它可(ke)(ke)以消除(chu)疲勞,恢復和(he)改善睡眠;一般(ban)60%氧(yang)氣濃(nong)度適合老年人,長期使用。老年人可(ke)(ke)以延(yan)長壽命;對于患者,90%的氧(yang)氣濃(nong)度符合醫用氧(yang)氣標(biao)準。
三、醫用制氧機氧氣濃度的標準為什么是93%±3%
根據國家(jia)食(shi)藥監(jian)部(bu)(bu)分(fen)(fen)有關規定醫(yi)用(yong)(yong)氧(yang)(yang)(yang)(yang)(yang)(yang)氣(qi)(qi)必須(xu)達到93%才(cai)算標(biao)(biao)準,才(cai)能(neng)在臨床(chuang)救治(zhi)中(zhong)投入使用(yong)(yong)。那醫(yi)用(yong)(yong)制氧(yang)(yang)(yang)(yang)(yang)(yang)機氧(yang)(yang)(yang)(yang)(yang)(yang)氣(qi)(qi)濃(nong)度(du)(du)的標(biao)(biao)準為什么是93%±3%?主要是因(yin)為人(ren)體在借助醫(yi)用(yong)(yong)制氧(yang)(yang)(yang)(yang)(yang)(yang)機吸(xi)氧(yang)(yang)(yang)(yang)(yang)(yang)時,同時還會(hui)吸(xi)入部(bu)(bu)分(fen)(fen)含有20.98%氧(yang)(yang)(yang)(yang)(yang)(yang)氣(qi)(qi)純度(du)(du)的空氣(qi)(qi),這(zhe)樣就真正吸(xi)入的氧(yang)(yang)(yang)(yang)(yang)(yang)氣(qi)(qi)濃(nong)度(du)(du)也(ye)會(hui)隨之被(bei)稀釋。據測試一般吸(xi)入喉部(bu)(bu)的氧(yang)(yang)(yang)(yang)(yang)(yang)氣(qi)(qi)濃(nong)度(du)(du)也(ye)就在45%左右。在根據人(ren)體結構(gou)特征,吸(xi)入氧(yang)(yang)(yang)(yang)(yang)(yang)氣(qi)(qi)要經過(guo)(guo)32級的衰減(jian)過(guo)(guo)程,其實真正下來,93%左右的氧(yang)(yang)(yang)(yang)(yang)(yang)氣(qi)(qi)濃(nong)度(du)(du),人(ren)體吸(xi)氧(yang)(yang)(yang)(yang)(yang)(yang)后(hou)被(bei)利(li)用(yong)(yong)的氧(yang)(yang)(yang)(yang)(yang)(yang)氣(qi)(qi)濃(nong)度(du)(du)也(ye)就約為30%。因(yin)此為了(le)保證患者能(neng)夠正常(chang)接(jie)受氧(yang)(yang)(yang)(yang)(yang)(yang)氣(qi)(qi)輔助救治(zhi),氧(yang)(yang)(yang)(yang)(yang)(yang)氣(qi)(qi)濃(nong)度(du)(du)必須(xu)達到93%左右,才(cai)能(neng)保證患者的用(yong)(yong)氧(yang)(yang)(yang)(yang)(yang)(yang)需求。
同樣在1988年國家醫藥管理局制定了并頒發了《醫用分子篩制氧設備通用技術規范》中,提到醫用制氧機的氧氣濃度(du)要大(da)于90%,也就是(shi)(shi)咱們(men)統稱的93%的氧濃度(du)。醫用制(zhi)氧設備按照規定屬于二類醫療(liao)器(qi)械管(guan)理(li),是(shi)(shi)由(you)省(sheng)級食品(pin)(pin)藥(yao)品(pin)(pin)監管(guan)部門進型審批、注冊(ce)。制(zhi)氧機(ji)都(dou)是(shi)(shi)在食品(pin)(pin)藥(yao)監監管(guan)部門的管(guan)理(li)范疇之內,既適用于醫院患者輔助治療(liao)和(he)特殊(shu)行(xing)業的用氧需求,也能為(wei)需要家(jia)庭氧療(liao)的患者提供有效的醫用氧氣。
