Abstract

Systems and methods are provided for intermittent microinfusion. A system may include a pump and an IV set that includes a y-port valve disposed below a pump interface portion of the IV tubing. The y-port valve may include an internal valve member that allows fluid to flow from the pump to a patient when no syringe is attached to the y-port. The internal valve member may be moved by the attachment of a syringe containing the medication to be infused to the y-port such that the fluid pathway from the pump to the patient is blocked and fluid from the syringe can be injected into the IV tubing between the y-port valve and the pump. The pump may retrograde pump the medication into the tubing via the y-port valve and then forward pump the medication to the patient when the syringe is removed from the y-port.
