Abstract: A retrograde disposable intravenous (IV) set is disclosed. The IV set includes a diverter housing between upper and lower portions of a fluid line, the diverter housing including a lower end and an upper end extending away from the lower end and the fluid line to a syringe port located in the upper end, and a diverter member within the diverter housing and configured to move within the diverter housing from a first position, at which a first opening through the diverter member forms a first fluid pathway between the upper portion and the lower portion of the fluid line, to a second position, at which the first fluid pathway is blocked and a second fluid pathway is formed between the upper portion of the fluid line and a syringe port. Retrograde infusion may occur when the diverter member is in the second position.

Abstract: Systems and methods of micro-infusion of medical fluids are disclosed. Micro-infusion systems may include a pump, a patient interface, tubing between the pump and the interface, and a micro-infusion device along the tubing. A first portion of the tubing above the micro-infusion device is longer than a second portion of the tubing below the device. The micro-infusion device may include a chamber in-line with the tubing, a first valve between the chamber and the first portion of the tubing, a second valve between the chamber and the second portion of the tubing and a third valve between the chamber and a dump chamber. The second valve may be slidably disposed within the chamber. A medical fluid may be provided into the chamber that slides the second valve displacing another fluid in the chamber through the third valve into the dump chamber.
