Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
162 words
A color-coded closure system for sealing and identifying fluid lines wherein the closure system comprises; a fluid line enclosure plug have a cylindrical configuration with a proximal end and a distal end, the proximal end of the plug having a substantially greater diameter than the distal end of the plug, the proximal end of the plug and the distal end of the plug having a juncture point defining a shoulder portion, a fluid line closure cap having a uniform cylindrical configuration with a proximal end and a distal end, the proximal end of the cap being closed, the distal end of the cap having an aperture therein, said aperture extending along the longitudinal center line of the closure cap to a predetermined distance short of the proximal end of the cap, the distal end of the plug adapted to be matingly engaged with the aperture of the cap for storage purposes, the plug and the cap being color coordinated in predetermined colors.
Claim 2
Dependent Claim
162 words
A color-coded closure system for sealing and identifying fluid lines wherein the closure system comprises; a fluid line enclosure plug have a cylindrical configuration with a proximal end and a distal end, the proximal end of the plug having a substantially greater diameter than the distal end of the plug, the proximal end of the plug and the distal end of the plug having a juncture point defining a shoulder portion, a fluid line closure cap having a uniform cylindrical configuration with a proximal end and a distal end, the proximal end of the cap being closed, the distal end of the cap having an aperture therein, said aperture extending along the longitudinal center line of the closure cap to a predetermined distance short of the proximal end of the cap, the distal end of the plug adapted to be matingly engaged with the aperture of the cap for storage purposes, the plug and the cap being color coordinated in predetermined colors.
