A low power circuit for medical drip infusion monitoring system
We developed a low power monitor for medical drip infusion monitoring system, it can operate for a year, and longer than other designs. The monitoring system consists of many drip infusion monitoring nodes and a monitoring center, and transmits the message by the Zigbee wireless sensor network. The capacitive sensor in the monitor node differentiates that air and water are different dielectric material, and has a feature of low power consumption. The status of the drip infusion tube is detected by the capacitive sensor, the monitor transmits the alarm message to the monitoring center when there is no water in the drip infusion tube, the nurses can handle quickly the drip infusion task.
