Medical Check Valves

Qosina offers an extensive line of medical check valves available in a variety of styles, in stock and ready for immediate delivery. High-flow valves feature low flow resistance, low opening pressure, and positive seal against backflow. In-line check valves feature low cracking pressure, which determines when the component starts to open; if back pressure is a concern, choose from our variety of duckbill check valves. Luer activated check valves are equipped with a needle-free design featuring a closed silicone plug that blocks flow until mechanically opened with a male luer connector. Dual check valves enable injection and aspiration from separate ports of a single connector. Qosina offers components from various check valve manufacturers with assorted flow rates, materials, cracking pressure and back pressure options. Single-use medical device check valve sample kits are also available for purchase and are ideal for testing.

In stock and available for immediate delivery, DEHP-free, acrylic in-line check valves feature latex-free silicone diaphragms that allow flow in one direction and will prevent retrograde flow (back pressure tested to various psi ratings). The in-line check valves have various cracking pressure ratings, and feature a versatile design making it a superior choice for inclusion by original equipment manufacturers as a component in various applications. Qosina also stocks a variety of check valves to complete your project including one-way duckbills, high flow and in-line, along with luer activated and dual check valves.

Hemostasis Valves from Qosina

Qosina offers an extensive line of Hemostasis Valves. Available in a variety of styles including Y-Connector, Double Valve, and One-Handed, they are designed to minimize fluid loss and backflow. The Y connector gives the valve an ergonomic design for comfortable handling and the female luer lock equipped side port can be used to check pressure, as well as helps with irrigation, and prevents thickening of fluid. Double Valves are designed with two hemostasis ports to accommodate multiple guide wires without tangling, which allows for easier manipulation and control. One-Handed Valves have a self-closing mechanism and can automatically move from open to close. The Qosina One Handed Hemostasis Valve Y Connector, with a rotating male luer lock connection and a female luer lock side port can accept multiple guide wires and features three positions; open, semi-open, and closed. Hemostasis Valves range from fully closed to 10 FR, and have a Polycarbonate body; allowing for enhanced visualization of fluids or guide wires moving through the housing. All valves have either a male luer slip or a rotating male luer lock which allows for simple connection to a mating luer.
