Valved connector for medical lines

Valved male luer connector comprising:

• a casing, a tubular member having an inlet portion and an outlet portion with an open terminal end,
• an elastic hollow element secured to the casing and enclosing the tubular member, said elastic hollow element having a terminal wall, which normally seals closed said terminal end of the outlet portion of the tubular member and having a cut,
• a collar interposed between the casing and the elastic hollow element and axially displaceable, following thrust engagement by a female connector connectable to said male connector, causing a stretching deformation of said elastic hollow element and consequent opening of the flow passage between said inlet portion and said outlet portion of the tubular member, and
• a priming cap releasably connectable to the casing of the connector to provide stretching deformation of said elastic element and to keep said terminal end of the outlet portion of the tubular member in communication with the atmosphere through a liquid-impermeable barrier, said priming cap comprising a skirt arranged outside the casing and configured to engage said casing and a tubular part coaxial to said skirt, which carries said liquid-impermeable barrier and is arranged to interact with said collar interposed between the casing and the elastic hollow element.
