Abstract
A circuitry for counting drips and monitoring a rate of infusion is incorporated into an IV administration set. The circuitry includes a pair of leads that are positioned in the pathway of fluid droplets, such that each droplet simultaneously contacts both leads. As such, the leads act as a virtual switch that is closed by the presence of a droplet. This event is then displayed on a drip signaling device to aid a user in adjusting the infusion rate of the IV administration set.
