Abstract
An automatic detecting and prewarning system for medicine instiller mainly includes a clamp for easily clamping on a flow-indicating cylinder of the medicine instiller, detecting means of an electronic sensor type mounted on the clamp, alarm means connected to the detecting means via a conductor, and a drop carrier pivotally connected to a lever to locate in the flow-indicating cylinder below a medicine dropper. After a fixed number of drops or flow per minute is set for the medicine instiller and input to the alarm means, medicine drops fallen from the medicine dropper one by one impact on and reciprocatingly sway the drop carrier to intermittently cut off the detecting means as a control signal to the alarm means. When an abnormal number of drops or flow per minute continues for a preset time, the alarm means is automatically enabled to emit warnings.
