Abstract
A catheter connector includes an inner wall that defines an interior of the catheter connector and is transmissive to ultraviolet (UV) light. An outer wall defines an exterior of the catheter connector. One or a plurality of UV light sources is disposed between the inner wall and the outer wall or on the outer wall positioned to emit UV light into the interior of the catheter connector. A flow sensor is provided for sensing a flow of fluid in the interior of the catheter connector, and circuitry electrically connects the UV light sources, the flow sensor and a power source, such that electrical power is supplied to the UV light sources when a fluid flows through the interior of the catheter connector.
