Abstract:
1. A medical valve connector comprising: a tubular body having an inlet fitting of the male luer or luer-lock type which can be coupled by screwing with a complementary female luer or luer-lock fitting; an outlet fitting coaxial to said inlet fitting, said outlet fitting at a distal end and said inlet fitting at a proximal end of said body; and means defining a passage of flow between said inlet and outlet fittings, said male inlet fitting comprising an outer internally-threaded tubular element and an inner tubular element, said inlet fitting bounded at a distal end by a collar separating said inlet fitting from an internal chamber, said collar having an opening allowing said inner tubular element to extend from said inlet fitting into said chamber; said inner tubular element having an outer end and an inner end and being axially open at both said inner and said outer ends, said inner tubular element being axially displaceable but not rotationally displaceable with respect to said outer tubular element and to said body, following coupling with said complementary female fitting, from a retracted closing position to an advanced position for opening said passage of flow; said inner tubular element comprising a flange in said internal chamber, said flange extending radially from said opening to an inner surface of said tubular body and abutting said collar in said retracted position, said inner tubular element having a diameter smaller than said flange distal of said flange and proximal of said flange; sliding-seal means between said inner tubular element and said body, and elastic means tending to keep said inner tubular element in said retracted position, wherein said means defining the passage of flow, said sliding-seal means and said elastic means are integrated in a generally tubular unitary body of elastic material set axially in a sealed way between said inlet and outlet fittings and formed with a transverse diaphragm having a pre-cut which is opened elastically by said internal end of said inner tubular element when said inner tubular element is in said advanced opening position.
