摘要

This paper introduces the structure and working principle of a new type of automatic medicine renewing and final alarming intravenous infusion device. The control system and the choosing of stepping motor are also discussed. Experiments show that this device can open and close the infusion tubes effectively so the medicine can be renewed automatically, and sound the alarm finally. With this device, the unattended infusion can be realized, the medical labor intensity can be effectively reduced, the clinical safety and work efficiency can be improved.
