Fluid conveying conduit
A fluid-containing conduit ( 10,30,40,50 ) including at least one luminescent marker ( 14 ) whereby the fluid-containing conduit is visible in a low light condition. The marker may be in the form of one or more elongate ribs ( 16 ) containing luminescent material along interior wall surface ( 18 ), or may be elongate luminescent bands ( 52,54 ) adjacent the exterior wall ( 20 ) of the conduit, or may be indicia containing luminescent material such as ink ( 42 ).
1. A fluid conveying conduit comprising: a conduit body having at least one elongate rib integrally disposed adjacent an inner surface of said conduit body, said elongate rib projecting outwardly from said inner surface and continuously extending along the entire length of said conduit body, said elongate body having a translucent portion and said rib including a luminescent pigment sufficient to render the entire length of said conduit body visible in a low light condition.
2. The fluid conveying conduit according to claim 1 , wherein said conduit body further includes one or more dyes or secondary pigments which emit or reflect incident light in a predetermined range of wavelengths.
3. The fluid conveying conduit according to claim 1 , wherein said conduit body includes a transparent portion.
4. The fluid conveying conduit according to claim 1 , wherein said conduit body further includes a luminescent pigment.
5. The fluid conveying conduit according to claim 4 , wherein said luminescent pigment comprises a phosphorescent pigment.
6. The fluid conveying conduit according to claim 1 , wherein said luminescent pigment further includes one or more dyes or secondary pigments which emit light in a predetermined range of wavelengths.
7. The fluid conveying conduit medical tube according to claim 1 , wherein said conduit body further includes an antimicrobial additive.
8. A fluid conveying conduit, comprising: a conduit body having at least one elongate band lying embedded within said wall of said conduit body-and continuously extending along the entire length of said conduit body, said conduit body having a translucent portion and said at least one elongate band including a luminescent pigment sufficient to render the entire length of said conduit body visible in low light.
9. The fluid conveying conduit according to claim 8 , wherein said at least one elongate band has a portion coterminous with an outer surface of said conduit body.
10. The fluid conveying conduit according to claim 8 , wherein said conduit body further includes one or more dyes or secondary pigments which emit or reflect incident light in a predetermined range of wavelengths.
11. The fluid conveying conduit according to claim 8 , wherein said conduit body includes a transparent portion.
12. The fluid conveying conduit according to claim 8 , wherein said conduit body further includes a luminescent pigment.
13. The fluid conveying conduit according to claim 12 , wherein said luminescent pigment comprises a phosphorescent pigment.
14. The fluid conveying conduit according to claim 8 , wherein said conduit body further includes an antimicrobial additive.
