隨著電(dian)(dian)子醫(yi)用(yong)(yong)設備在(zai)醫(yi)院(yuan)的(de)廣泛(fan)應用(yong)(yong)，我們(men)發(fa)現患(huan)(huan)者和(he)醫(yi)生已經深(shen)陷電(dian)(dian)子儀器(qi)和(he)設備的(de)包圍之(zhi)中，漏電(dian)(dian)流(liu)(liu)對(dui)患(huan)(huan)者構成的(de)潛在(zai)威脅也(ye)遠(yuan)遠(yuan)大于(yu)以前，尤其(qi)是患(huan)(huan)者在(zai)手術中或(huo)麻藥下，各種(zhong)電(dian)(dian)極。傳感(gan)器(qi)直接插患(huan)(huan)者其(qi)微弱的(de)漏電(dian)(dian)流(liu)(liu)直接流(liu)(liu)過患(huan)(huan)者的(de)心(xin)臟，就會導致觸(chu)電(dian)(dian)身亡。目前，我國(guo)大多數醫(yi)院(yuan)配(pei)電(dian)(dian)系統為了(le)滿足醫(yi)院(yuan)中一些重要(yao)場所對(dui)不間斷供(gong)電(dian)(dian)的(de)實用(yong)(yong)要(yao)求。故醫(yi)院(yuan)2類場所：如中心(xin)手術部的(de)所有手術室，所有CU病房（包括(kuo)ICU，cCU，NICU，PICU，SICU等）和(he)心(xin)臟導管介人室等都采(cai)用(yong)(yong)了(le)醫(yi)用(yong)(yong)隔離(li)電(dian)(dian)源（IT）系統供(gong)電(dian)(dian)。

隨著電(dian)(dian)(dian)子(zi)醫(yi)用設(she)備在(zai)(zai)醫(yi)院的(de)廣泛應用，我們發現患者(zhe)和(he)醫(yi)生(sheng)已經深陷電(dian)(dian)(dian)子(zi)儀(yi)器(qi)和(he)設(she)備的(de)包圍之中，漏電(dian)(dian)(dian)流(liu)對患者(zhe)構成的(de)潛在(zai)(zai)威(wei)脅也遠遠大于以前，尤其是(shi)患者(zhe)在(zai)(zai)手(shou)術(shu)中或(huo)麻藥下，直流(liu)隔離電(dian)(dian)(dian)源(yuan)(yuan)，各種電(dian)(dian)(dian)極。醫(yi)用隔離電(dian)(dian)(dian)源(yuan)(yuan)系統(IT系統)目(mu)的(de)就(jiu)是(shi)保證為該場所內的(de)電(dian)(dian)(dian)器(qi)提供一個(ge)的(de)電(dian)(dian)(dian)源(yuan)(yuan)，以確(que)保的(de)安全。 當電(dian)(dian)(dian)網負(fu)載端出現個(ge)絕緣故障點時，不(bu)會(hui)引起電(dian)(dian)(dian)源(yuan)(yuan)空開動(dong)作(zuo)（跳閘(zha)），保證了(le)供電(dian)(dian)(dian)的(de)連續(xu)性(xing)。
