Infusion pumps are devices used to administer intermittent or continuous delivery of fluids, medication, nutrients, and blood or blood products directly into a patient's circulatory system via an IV. These pumps offer practical administration of small amounts of fluids which may vary in volume throughout different times of the day. There are several types of infusion pumps, the most common being the peristaltic pump which uses a tubing set to pump fluids from a drip bag to the patient. The other most common form of infusion pump is a syringe pump, which replaces the drip bag with a syringe containing medication. In addition to these models, other specialized pumps are used in healthcare settings such as a Patient Controlled Analgesia (or PCA) pump that allows a patient to control the amount of pain medication being infused. IV pumps can either be stationary or ambulatory and can run on AC or battery power. Some IV pumps have advanced features, such as an optional software that counter-checks dosage amount for safety, and a log feature that generates reports. IV pumps can meet various clinical needs and provide safe, accurate, and efficient administration of intravenous fluids.
