Claim:
1. A flow system for medical lines comprising: a flow component having a main duct for a primary fluid and at least one lateral tubular fitting with a female luer cone communicating with the main duct through a valve; said valve comprising a transverse diaphragm formed by a bottom wall of a cup-shaped element made of elastically deformable material, and a male luer-cone introducer of secondary fluid: said cup-shaped element having an outer peripheral edge normally kept in fluid-tight contact against an annular valve seat of said at least one lateral tubular fitting: said male luer-cone introducer of secondary fluid, insertable into said at least one lateral tubular fitting with female luer cone to displace said transverse diaphragm into an opening position; said diaphragm prearranged for being pushed into said opening position as a result of a direct contact of thrust by said introducer, said lateral tubular fitting configured to couple in a fluid-tight way with said introducer before said introducer comes into the contact of thrust with said diaphragm; said lateral tubular fitting formed of a relatively yielding elastic material and expandable elastically in a radial direction following upon fluid-tight coupling with said introducer; a side wall of said lateral tubular fitting having two diametrically opposite axial portions which are thinner than remaining portions of said sidewall; and wherein said diaphragm is formed with a ring of axial projections radially facing a base of said female luer cone such that a contact of said introducer with said ring of axial projections allows a flow from the introducer into said main duct.
