Abstract
The anti-back-flow devices and methods prevent fluid from leaking proximally from a catheter, but allow ready access to the catheter using any male luer device. The devices include proximal surfaces that urge open a valve in response to force from a male luer tip. The valves are associated a female luer hub and adapted to function with standard and typical non-standard male luer fittings.
Claims11
A device for adapting a male luer fitting to a catheter, the device comprising:
- a female luer hub having an inner central channel comprising a proximal tapered receiver for a male luer connector;
- an adaptor located in the inner central channel and comprising a proximal contact surface, an adaptor body, and a distal contact surface;
- and
- two or more struts each extending in a serpentine path between the female luer hub and the adaptor body wherein the two or more struts are configured to deflect upon advancement of the male luer fitting against the proximal tapered receiver to move the adaptor body distally, and wherein the two are more struts urge the adaptor body proximally upon removal of the male luer fitting.
