Abstract:
1. An adaptor for discriminating connection of an oral tip having a length greater than 0.50 in. (12.70 mm) to a feeding line and for preventing sealed connection with a standard semi-rigid luer tip having a length less than or equal to 0.50 in (12.70 mm), the adaptor comprising: a body having first and second open ends and a passage for flow of fluid from the first end to the second end; an oral tip connector defining a connection port in the passage adjacent the first end of the body, the connection port being sized and shaped to sealingly receive the oral tip and to prevent sealing connection with the standard semi-rigid luer tip having a length less than or equal to 0.50 in (12.70 mm); a duckbill valve in the passage between the first and second open ends of the body, said duckbill valve comprising valve flaps that are biased toward a closed position in which the flaps are in sealing contact with one another at an apex of the valve to substantially seal the second open end of the body from the connection port, the duckbill valve being spaced at least 0.50 in (12.70 mm) downstream from the first open end of the body such that when the oral tip is fully inserted into the connection port, the oral tip engages the valve flaps and opens the valve, and when the standard semi-rigid luer tip is fully inserted into the connection port, the standard semi-rigid luer tip does not contact the valve flaps and the valve flaps remain in said closed position.
