The real time monitoring of infusion without artificial chaperone can create a ringless ward for hospitals, improve the level and efficiency of nursing service and enhance patients' satisfaction.

The intelligent infusion tube and control system can automatically distinguish the types and specifications of the infusion apparatus, the residual dosage of the infusion, the estimated residual time, the discrimination of the plugging needle, the leakage needle, the empty bottle and the drop stop. The system can transmit the information of the infusion state of each bed to the nursing station, the two level nursing station and the nurse's handheld PDA through the net work. In every area of the ward, we can see the infusion process of each bed. Meanwhile, the system can mind the nurses to change the liquid by pictures and voice hints.
