Abstract:
1. A valve connector for medical infusion lines consisting of a tubular body having an inlet for insertion of a fluid introducer and an outlet, a hollow spike set axially within the cavity of the tubular body and having a closed tip facing said inlet and set at an axial distance from the latter, said hollow spike being in communication with said outlet of the tubular body, and a sealing member including an elastic head with a pre-slit, said elastic head being normally set in an undeformed condition within said inlet, in which said pre-slit is closed, and being displaceable axially against said closed tip of the hollow spike, as a result of insertion of said fluid introducer within the inlet, to assume an elastically deformed condition of opening of said pre-slit, said sealing member moreover including a hollow elastic element joined to said head and defining an elastic thrust means tending to keep said head in said undeformed condition, wherein said outlet comprises a pierceable injection point coaxially facing said hollow spike and consisting of a terminal tubular appendage formed integrally with said hollow spike, and a diaphragm made of elastic material blocked within said terminal tubular appendage, wherein said outlet further includes at least one lateral tubular fitting set transverse to said terminal tubular appendage, wherein the valve connector comprises a pair of lateral tubular fittings set coaxially opposed to one another, wherein said pair of lateral tubular fittings are formed integrally with said hollow spike and said terminal tubular appendage, wherein a flange is formed integrally with said pair of lateral tubular fittings, said hollow spike, and said terminal tubular appendage, and wherein said flange radially extends beyond an outer surface of the tubular body and over a substantial axial portion of each lateral tubular fitting, and wherein said terminal tubular appendage comprises an inner annular shoulder and an outer turned-in edge defining therebetween a blocking seat for said diaphragm made of elastic material.
