A primary secondary infusion continuity device is a medical device that is used to continuously infuse medications or fluids to keep a patient's body balanced with medication or hydration.
A primary infusion device is usually an infusion pump that is able to infuse medications precisely as prescribed. A secondary infusion device, on the other hand, is an ancillary device, usually a simple dropper or gravity feeder, that is used to simultaneously infuse saline or other fluids.
