Abstract
A generally rigid molded plastic catheter hub attachment (16, 52, 74) includes one or more co-molded elastomeric gaskets (22, 58).
Claims27
A catheter hub attachment of a catheter insertion device comprising:
- a generally rigid molded plastic nose having an internal passageway therethrough and through which a catheter insertion needle can slidingly pass and having an exterior wall sized to fit within a catheter hub;
- an elastomeric first gasket integrally associated with the internal passageway whereby to create a seal around a catheter insertion needle passing through the internal passageway;
- and
- an elastomeric second gasket integrally associated with the exterior wall whereby to create a seal with a portion of an internal wall of a catheter hub into which the nose is fitted.
