An in-line backflow valve is a single-use device inserted into medical or lab tubing to block unwanted reverse flow of fluids or gases. Clinically, it protects patient circuits, infusion lines, or lab systems from contamination or pressure surges by automatically sealing when backflow is detected.
These valves are typically classified as single-use medical devices and must comply with relevant regulations for their intended use. They are often supplied sterile and pre-connected to tubing, requiring no additional assembly before use.
