Flow regulator for medical liquids and method for its fabrication

A flow regulator for medical liquids comprising a first body having a tubular inlet connector and a second body having a tubular outlet connector, said first and second bodies being made of moulded plastic material and being coupled to one another in a mutually rotatable way about an axis of rotation with the interposition of a gasket made of elastomeric material, at least one dosing passage being provided between said first and second bodies and through said gasket to open progressively the communication between said inlet connector and said outlet connector by means of the relative rotation of said first and second bodies;

• said second body having at least one graduated peripheral side scale and said first body having a pointer co-operating with said at least one graduated scale for visualizing the relative angular position between said first and second bodies corresponding to the regulation selectively set of the flow of liquid from said inlet connector to said outlet connector through said at least one dosing passage, wherein said at least one graduated scale includes at least one of impressions and reliefs formed integrally by moulding on said second body, and said gasket consists of an element overmoulded on said second body and having a side skirt formed with at least one of openings and inserts coupled in a complementary way with at least one of said reliefs and said impressions of said second body for completing said at least one graduated scale.
