Description
By using negative ion and Dual UVC + UVA technology, purify indoor and car air in just 6 minutes. Negative ions actively attract the polluted microparticles in the air which are always positively charged, thus making the invisible PM2.5 form into clusters and fall down. The negative ions can damage the bacterial protein to make them weak or dead, thus making air purified and deodorized. UV technology could stimulate the catalytic action of the photocatalyst, to generate more hydroxyl radicals and active oxygen ions. It is turning oxygen and water into a strong oxidizing active oxygen anion (. O2) and hydroxyl radicals (.OH), which is able to oxidize bacteria and viruses.

檢查項目:
心臟超聲波 + 報告 + 醫生分析
甚麼是心臟超聲波?
心臟超聲波 Echocardiogram
超聲波心動圖是用超聲波來顯示心臟結構的一種方法。
超聲波探頭首先可以產生人類耳朵無法聽見的高頻音波,經過胸壁進入身體, 探測心臟位置,反射後再被探頭接收,訊號經電腦重組後變成圖像,用以評估心臟機能以及是否運作正常。利用超聲波心動圖檢查可以獲得即時影像,清楚了解心臟整體收縮的情況是否正常,也可以知道心瓣膜病引起的狹窄或倒流的情況,以及心膜炎時,心包膜內是否有積水等等。同時也能測量肺動脈內的血壓,幫助診斷多種與心臟和肺部有關的疾病。
心臟超聲波檢查對病人無害、無痛苦、方便安全,但也有其局限性,例如超聲波心動圖只能顯示心臟的局部結構,冠狀動脈並無法顯示在電腦熒幕上,需要配合更多檢測進行診斷。
