Abstract

A device for dispensing fluid to a patient and indicating a fluid flow condition. The device includes a reservoir configured to provide a source of fluid under pressure. A continuous flow path in fluid communication with the source of fluid provides a continuous and substantially constant flow rate of fluid from the source to a patient. The device further includes at least one flow detector in fluid communication with the continuous flow path. The flow detector is configured to provide a signal that the flow rate of the fluid in the continuous flow path is different from a predetermined flow rate, thereby indicating a fluid flow condition.
