Current Sensing Amplifiers for Medical Infusion Pumps

An infusion pump delivers fluids, medication, or nutrients to a patient via the circulatory system, subcutaneously, or epidurally, via controlled pressure injecting. An infusion pump is used when it is otherwise impossible to treat a patient at the prescribed times and quantities, such as in minute quantities smaller than what a drip system can deliver.
