Infusion apparatus toppling closure device

The utility model discloses an infusion apparatus toppling intercepting device which comprises an induction end and an intercepting end. The sensing end comprises an inclination sensor, and the inclination sensor is arranged on the infusion tube or the infusion bag through a fixing mechanism; the cut-off end comprises an extrusion mechanism arranged on the outer side of the infusion tube body in asleeving manner, and a motor for providing power for the extrusion mechanism; and the inclination sensor and a power supply of the motor form a loop. According to the utility model, the inclination sensor for sensing the inclination change of the angle is arranged on the infusion tube, and the inclination sensor senses the inclination change of the angle so as to control the extrusion mechanism at the interception end to extrude and intercept the infusion tube through the motor, so that the corresponding speed is high, and the interception effect is obvious; and accidents such as bubble mixing into liquid and blood b
