pipe groove is formed in the portion, coinciding with the first partition plate, of the bottom face of the first shell, and the first
pipe groove is used for being clamped on a pipeline, located above a Murphy type dropper, of an infusion
pipe; the second shell is of a directional structure with an opening in the upper end, a second partition plate is arranged in the second shell in the width direction, and a second pipe groove is formed in the portion, coinciding with the second partition plate, of the bottom face of the second shell. The
system is used for replacing manual operation to monitor the infusion condition, and can control the bedside calling bell to give an alarm at the first time after liquid in the infusion
