NP Medical Inc. products

The NP Medical Inline Check Valve is the valve of choice for market-leading infusion therapy OEMs. This normally closed valve is designed to open at low fluid pressures in the flow direction and prevent backflow into the primary IV line from secondary (piggyback) sets. With over a billion valves sold, this Inline Check Valve’s time proven design with uniform 360-degree seal provides maximum protection against retrograde flow even at low pressures, and thereby reduces the risk of medication not getting to the patient;¹ prevents dilution of drugs being administered to the patient, and secondary infusate from mixing with primary infusate;² and constrains backflow of blood from cannula to the IV tubing.²

The Pressure Activated Valve is used extensively as a "one-way" valve in critical drug delivery applications, and as an "anti-siphon" valve in pump applications. It targets patient applications requiring very specific performance characteristics such as high-pressure rating and narrow specification ranges for key attributes. The valve features a preloaded, normally closed silicone diaphragm that allows flow in one direction while checking flow in opposite direction and preventing retrograde flow. The valve`s clear housing facilitates visualization of the entire fluid path.
