Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
187 words
An injection site device for a parenteral fluid administration system, comprising a generally tubular injection port having an outlet, an inlet end and a bore; an elastomeric plug, a portion of which extends within the bore of the inlet conforming generally to the bore, the plug having an annular outwardly extending flange which generally covers the end of the inlet; and a cap member having a top portion having a central aperture and a skirt portion having an inner wall fitting around and generally conforming to a portion of the outer wall of the port inlet, the cap skirt including a plurality of longitudinal projections beginning at about the top portion of the inner wall of the skirt and tapering in a downwardly direction, the cap member compressingly engaging the flange of the plug by means of a bond between at least a portion of the longitudinal projections on inner wall of the skirt of the cap and the outer wall of the port, the engagement resulting in projection of at least a portion of the top of the plug through the aperture of the cap member.
Claim 2
Dependent Claim
187 words
An injection site device for a parenteral fluid administration system, comprising a generally tubular injection port having an outlet, an inlet end and a bore; an elastomeric plug, a portion of which extends within the bore of the inlet conforming generally to the bore, the plug having an annular outwardly extending flange which generally covers the end of the inlet; and a cap member having a top portion having a central aperture and a skirt portion having an inner wall fitting around and generally conforming to a portion of the outer wall of the port inlet, the cap skirt including a plurality of longitudinal projections beginning at about the top portion of the inner wall of the skirt and tapering in a downwardly direction, the cap member compressingly engaging the flange of the plug by means of a bond between at least a portion of the longitudinal projections on inner wall of the skirt of the cap and the outer wall of the port, the engagement resulting in projection of at least a portion of the top of the plug through the aperture of the cap member.
