Abstract

The disclosure provides self-illuminating tubing that may be uncoupled from external power sources. The disclosed tubing is useful in a variety of low-light environments. Applications include medical devices and tubing for use in building construction and for industrial purposes. Embodiments in which the illuminating material indicates where tubing has been damaged are also disclosed.

Claims

1. A self-illuminated tubing, comprising:

an elongate wall defining an interior channel for transporting a substance, and defining an exterior surface of the tubing, the elongate wall comprising a first end, a second end, and a central portion between the first and second ends; and

a self-illuminating material that is disposed on or within the elongate wall.

2. The self-illuminating tubing according to claim 1, wherein the self-illuminating tubing is configured for use as medical tubing.

3. The self-illuminating tubing according to claim 1, wherein the self-illuminating material comprises a phosphorescent material.

4. The self-illuminating tubing according to claim 3, wherein the self-illuminating material comprises one or more of silica aluminate, strontium aluminate, aluminate with fluorescent pigment, alkaline earth silicate, and zinc sulfide.

5. The self-illuminating tubing according to claim 1, further comprising one or more concentric layers of tubing.

6. The self-illuminating tubing according to claim 1, wherein the self-illuminating tubing is configured for use as industrial tubing.

7. The self-illuminating tubing according to claim 1, wherein the self-illuminating tubing is configured for use as household tubing.

8. The self-illuminating tubing according to claim 1, wherein the self-illuminating material comprises a fluorescent material.

9. The self-illuminating tubing according to claim 8, wherein the illuminating material comprises one or more of calcite, amber, rubies, diamonds, emeralds, willemite, esperite, wollastonite, clinohedrite, hexavalent uranium, divalent manganese, trivalent chromium, trivalent lanthanides, divalent europium, tungsten-molybdenum in solid solution, sphalerite, crude oil, anthracene, stilbene, vitamin B2, tonic water, and fluorite.

10. The self-illuminating tubing according to claim 1, wherein the self-illuminating material comprises a chemiluminescent material.

11. The self-illuminating tubing according to claim 10, wherein the self-illuminating material comprises one or more of luminol in alkaline solution with hydrogen peroxide in presence of iron or copper, white phosphorous in moist air, and ozone mixed with nitric acid.

12. The self-illuminating tubing according to claim 1, wherein the self-illuminating material comprises a crystalloluminescent material.

13. The self-illuminating tubing according to claim 1, wherein the self-illuminating material comprises an electroluminescent material.

14. The self-illuminating tubing according to claim 13, wherein the self-illuminating material comprises one or more of zinc sulfide with copper or silver, zinc sulfide with manganese, natural blue diamond with boron, semiconductors with indium phosphide, gallium arsenide, and gallium nitride.

15. The self-illuminating tubing according to claim 1, wherein the self-illuminating material comprises a mechanoluminescent material.

16. The self-illuminating tubing according to claim 15, wherein the self-illuminating material comprises one or more of quartz, pressure sensitive tape, sugar crystals, cracking ice, sodium chloride, potassium chloride, potassium bromide, polycrystalline chips of lithium fluoride, and ferroelectric polymers.
