An alert device for use with an intravenous drip, comprises two induction ends and a control unit. The control unit further comprises a circuit module, an alarm module and a power module. The two induction ends are located on a pipe of the intravenous drip and are contacting with an injection solution inside the pipe. The two induction ends are electrically connected to the control unit by wires. The circuit module detects the induction ends to determine whether the induction ends are in an open circuit status or not. The circuit module connects to the alarm module. The power module supplies power for the control unit. The induction ends uses the injection solution as an conducting means to form a electrically closed loop, as a result, when the induction ends do not contact with the injection solution, the induction ends become an open loop, and thus the circuit module informs the alarm module to generate alarm signals.一種點滴器警示裝置,係結合於點滴裝置之一藥管上,其包括:兩感應端、以及一控制端。該控制端更包括:一電路模組、一警示模組、以及一電源模組。兩感應端係分別設置於該藥管之上,並與該藥管內之一注射液接觸。該控制端係透過兩纜線分別與兩感應端電性連接。電路模組係用以連接偵測該感應端並判斷是否為斷路狀態,且與該警示模組電性連接,而該電源模組則提供該控制端之電力來源。兩感應端透過接觸該注射液作為導電媒介,並藉由該纜線與該控制端形成一電性迴路狀態。當兩感應端無法接觸到該注射液時,該兩感應端之間遂形成一電性斷路狀態,且該控制端之電路模組將透過該警示模組對外予以警示。1‧‧‧點滴器警示裝置11‧‧‧感應端111‧‧‧偵測端112‧‧‧導電端12‧‧‧控制端121‧‧‧電路模組1211‧‧‧訊號輸出埠122‧‧‧警示模組123‧‧‧電源模組124‧‧‧節電模組13‧‧‧彈性夾體131‧‧‧夾合端132‧‧‧導線133‧‧‧尾端3‧‧‧纜線4‧‧‧訊號輸出線8‧‧‧護理站9‧‧‧點滴裝置91‧‧‧藥管92‧‧‧注射液
