Connector with protection valve for medical infusion/transfusion lines

摘要

A connector (1) for medical infusion/transfusion lines, catheters and the like, comprising a tubular body (2) with a protection valve (3) including an obturator formed by a resilient disk (15) having a circumferential sealing edge (15a) normally co-operating under closing contact with an annular valve seat (9) having a conical surface. On the side opposite to the annular valve seat (9), the obturator disk (15) bears against an annular reaction surface (14) of the body (2), and opening of the protection valve (3) is operated by axial displacement of a tubular push member (17) acting so as to press the central area of the obturator disk (15) into the annular reaction surface (14) thus elastically stretching it in the axial direction, whereby the circumferential sealing edge (15a) of the obturator disk (15) radially retracts, moving away from the annular valve seat (9).
