This invention relates to a safety liquid delivery connection device, comprising a casing and a plug block. The casing has a first end, a second end, and a central passage lying therebetween. The central passage has an upper annular surface, a lower annular surface, and a working surface lying therebetween. The upper and the lower surfaces are respectively communicated with the first and the second ends. The plug block is elastically deformable and disposed in the central passage and has a bottom surface and a non-penetrating slit. The plug block also can be switched between a leakage stopping position and a liquid conduction position. When the plug block is located at the leakage stopping position, the non-penetrating slit is sealed and the bottom surface is in contact with the lower annular surface to close the central passage when the plug block is located at the liquid conduction position, the non-penetrating slit is propped open and the bottom surface is retreated from the lower annular surface to open the central passage for the liquid to flow through. Accordingly, this invention has advantages of needle-free to reduce the risk of being stabbed and infected and convenience of synchronously completing connection and infusion.本發明係有關一種安全液體傳送連接裝置,其包括一殼體及一塞塊。殼體具有一第一端、一第二端及一介於其間之中央通道;中央通道具有一上環面、一下環面及一介於其間之工作表面;上、下環面分別連通第一、第二端。塞塊設於中央通道內,呈可彈性變形,並具有一底面及一未貫穿切縫;且可於一止漏位置及一導液位置間變換。當位於止漏位置時,未貫穿切縫呈密合狀,且底面接觸下環面而封閉中央通道;當位導液位置時,未貫穿切縫呈撐開狀,且底面退離下環面而開啟中央通道,以供液體流通。故,本案兼具無針體可減少刺傷感染的風險,與連結及輸液同步完成相當方便等優點。10‧‧‧殼體11‧‧‧第一端111‧‧‧第一連接部12‧‧‧第二端121‧‧‧第二連接部13‧‧‧中央通道131‧‧‧導入漸擴錐部132‧‧‧導出漸縮錐部13A‧‧‧上環面13B‧‧‧下環面13C‧‧‧工作表面20‧‧‧塞塊21‧‧‧頂面22‧‧‧底面23‧‧‧錐狀外表面24‧‧‧未貫穿切縫91‧‧‧供液連接端92‧‧‧輸液連接端921‧‧‧導液缺口93‧‧‧液體液位置P2‧‧‧導液位置HC‧‧‧塞塊位移間隙
