Intelligent LED infusion alarm suitable for night infusion

The intelligent LED infusion alarm comprises a fixing clamp, the fixing clamp is provided with a clamping opening allowing an infusion tube to be clamped in, a circuit board is installed on the fixing clamp, and a power source, a switch, an alarm circuit, a night display circuit and a light source are installed on the circuit board. The positive electrode of the power supply passes through the light source and the switch and then returns to the negative electrode of the power supply to form a first loop, and the alarm circuit and the night display circuit are connected in parallel to form a parallel branch. The light source and the first photoresistor are respectively arranged at opposite positions on two sides of the infusion tube and are used for enabling the light source to irradiate the first photoresistor, a convex lens is arranged between the light source and the first photoresistor, and two ends of the convex lens are fixed on one side, close to the light source, of the fixing clamp.
