FLOW SYSTEM FOR MEDICAL LINES

摘要

A flow system for medical lines includes a flow component having a main duct and at least one lateral tubular fitting with a female luer cone communicating with the main duct) through a valve. The valve includes a transverse diaphragm normally kept in fluid-tight contact against an annular valve seat of the lateral tubular fitting, which can be moved away from this into an opening position following upon insertion of a male luer-cone introducer of fluid into the lateral tubular fitting. The diaphragm is prearranged for being pushed into the opening position directly by the introducer, and the lateral tubular fitting is configured to couple in a fluid-tight way with the introducer before the latter comes into contact of thrust with the diaphragm.

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 (12) 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; and said diaphragm is 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.
