THREE-WAY STOPCOCK

Sterile · Single-Use · IV Flow-Control Device

Product Overview:

The Three-Way Stopcock is a sterile, single-use medical device designed to provide controlled fluid flow through intravenous and other medical tubing systems. It consists of a three-way body with a rotatable handle that allows the user to control and direct the flow of fluids between connected lines, providing three-way flow (from inlet to outlet, inlet to side-port, or side-port to outlet). Manufactured from medical-grade, biocompatible polycarbonate, polypropylene and high-density polyethylene, it is available with red, blue or white handles in lipid-resistant and non-lipid-resistant variants, and as a version with an integrated extension line. The device is designed to provide secure connections and reliable fluid flow control during infusion therapy and other medical procedures.

Intended Use
The Three-Way Stopcock is intended to be used as a flow-control device for directing, stopping or allowing the flow of fluids between connected medical tubing lines. It may be used in intravenous administration, infusion therapy, pressure monitoring, blood sampling, medication administration and other clinical applications where controlled fluid flow is required. The device can be used wherever infusion of intravenous fluids or medication is required — including the simultaneous infusion of two different IV fluids, bolus IV injections through an existing access site, and blood sampling through an existing IV access site without a second vein puncture. It is intended for all age groups and should be used by, or under the supervision of, a qualified healthcare professional.
