ABSTRACT:
An automatic alarm device for dripping injection fluid bottle, which is installed in the bottle neck portion, and it comprises of a case body, a buoyant power switching device, a buzzer, and a flashing device. The buoyancy of injection fluid pulls a buoy, which is immersed in the injection fluid, upwardly, then the lower end of the buoy connecting rod is lifted up against a extension coil spring, thereby, the electric connection between contacts of power switching device is broken (power OFF position) by leaf spring force of the top contact of the power switching device; when the injection fluid in the bottle is almost completely utilized to a certain level, the buoy losts its buoyancy, and the extension coil spring pulls the lower end of the buoy connecting rod downwardly to push the top contact to be connected electrically to the button contact of the power switching device (power "ON" position), at this time, the power is ON and the buzzer will start to flash to alert the nurse or doctor to take immediate action for the patient.
