Publication number: 20170189667Abstract: 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.Type: ApplicationFiled: December 29, 2016Publication date: July 6, 2017Inventors: Robert VASKO, Stephen J. BOLLISH, Lawrence FARHAT, Daniel ABAL, Robert Dwaine BUTTERFIELD

Publication number: 20160040662Abstract: A pumping mechanism is disclosed that includes a plurality of peristaltic pumping actuators configured to selectively and sequentially compress adjacent portions of a first portion of an at least partially compressible pumping element having an inlet that is upstream of an outlet. The plurality of pumping actuators are further configured to reciprocate at a common drive frequency with a first phase offset between each adjacent pair of pumping actuators. The pumping mechanism also includes at least one compensation actuator arranged to selectively compress a second portion of the at least partially compressible pumping element that is disposed between the first portion and the outlet. The at least one compensation actuator is configured to reciprocate at an optimal displacement and at a modulation frequency that is an integer multiple of the fundamental drive frequency and with a second phase offset between the at least one compensation actuator and the adjacent pumping actuator.Type: ApplicationFiled: October 16, 2015Publication date: February 11, 2016Inventors: Robert D.
