Under normal conditions, the spring is in a pressure-free state, and the electromagnetic coil 44 is not energized. When the infusion channel needs to be blocked, the controller controls the electromagnetic coil 44 to be energized, and magnetic poles are formed at both ends of the blocking rod 42. The blocking rod 42 and the magnet 43 attract each other, so that the blocking head 41 moves toward the blocking groove, squeezes the infusion tube, and achieves the purpose of blocking the infusion. After the electromagnetic coil is powered off, the magnetism of the blocking rod disappears, and under the reaction of the spring, the blocking rod and the blocking head are pulled to reset. Of course, the infusion blocking mechanism is a mature prior art, as long as the structure that can realize the movement of the blocking rod and the blocking head toward the blocking groove is sufficient.
