Abstract:
1. A flow component for medical infusion/transfusion lines, comprising: a tubular body having a side inlet connector configured to allow a fluid introducer to be inserted therein, said inlet connector housing in a fluid-tight way an elastic sealing element having a generally cylindrical shape, axially blocked at its ends between two annular arrests, one of said annular arrests axially internal of said inlet connector and another of said annular arrests axially external of said inlet connector; said elastic sealing element having an axial cavity on a side of the external annular arrest of the inlet connector, said axial cavity defining a diaphragm of small thickness for traversal by said fluid introducer; said cavity of said elastic sealing element having a conical side surface converging toward said diaphragm of small thickness; said elastic sealing element having a second axial cavity on a side of said internal annular arrest of the inlet connector, said second axial cavity having a conical side surface converging toward said diaphragm of small thickness; said diaphragm situated in a median position of said elastic element between said cavity and said second cavity; and wherein said axially external annular arrest is formed by an annular end edge of said inlet connector formed monolithically relative to a remainder of said inlet connector, said inlet connector having an interior surface extending along an outer surface of said sealing element, said interior surface curving upwardly away from said tubular body over a top of said sealing element and downwardly to said external annular arrest to form a space between said interior surface and a top side of said sealing element, and said external annular arrest located in an immediate radial proximity of said cavity of the elastic sealing element and having an outer surface flush with an interior surface of said sealing element bounding said axial cavity to facilitate a centering of the fluid introducer in said diaphragm.
