Medical coupling site valve body

摘要

A medical coupling site (210) adapted to be directly coupled to a standard male luer includes a rigid housing (214) containing an elastomeric valve element (216) comprising a tubular body having a wall thickness which progressively increases in a direction away from an integral diaphragm (234) which closes the upper end of the body. The housing (214) includes an annular flange (229) having a locking edge (231) which frictionally engages the male luer when inserted through a slit (236) in the diaphragm, to lock the luer in position. A pair of reinforcing ribs (244, 246) are formed integrally with the diaphragm and extend radially inwardly toward each other from the tubular body wall to bias the slit closed. The ribs are reduced in thickness intermediate their ends to form hinge points to facilitate flexing of the diaphragm when the luer is inserted. <IMAGE>
