Abstract

A phototherapy treatment apparatus and methods are provided. In particular, the present disclosure provides a phototherapy treatment apparatus configured to diffusely transmit light emitted from a light source to a patient.

Claims (16)

1. A phototherapy treatment method comprising:

placing a patient on a top surface of a bed having at least one of a translucent or transparent material; generating light from a light source;

directing the generated light at one of a plurality of side surfaces of the bed so that the generated light transmits through the material of the bed to produce total internal reflection of the generated light; and

transmitting the generated light through a plurality of microstructures located on the top surface of the bed such that the light exits the plurality of microstructures having a more diffusive distribution so as to enhance the treatment of an ailment of the patient placed on the bed.

2. The phototherapy treatment method of claim 1 , which includes transmitting the light generated by the light source through a transition device structured to at least one of (i) focus, (ii) scatter or (iii) diffuse the light rays.

3. The phototherapy treatment method of claim 1 , wherein the plurality of microstructures are arranged on the top surface of the bed.

4. The phototherapy treatment method of claim 1 , further comprising:

placing the light source in contact with a heat sink to dissipate heat generated by the light source.

5. The phototherapy treatment method of claim 1 , wherein the plurality of microstructures include at least one of voids, cracks, or char particles.

6. The phototherapy treatment method of claim 5 , further comprising:

forming the plurality of microstructures via one or more of CNC machining, laser engraving, sand blasting, and chemical engraving.

7. The phototherapy treatment method of claim 1 , wherein the plurality of microstructure include greater than approximately 1000 cracks per square inch.

8. The phototherapy treatment method of claim 1 , wherein the top surface of the bed defines inwardly sloped channel to intersect the light transmitted from the one of the plurality of side surfaces and through the material of the bed, and wherein the inwardly sloped channel is configured to concentrate the light that exits the plurality of microstructures and increase an area of the patient exposed to the light.

9. The phototherapy treatment method of claim 1 , further comprising:

covering the surface of the bed with a cover pad having at least one of a transparent or translucent material, the cover pad being sealingly engages to the surface of the bed to prevent liquid from contacting the light source and to provide a cushion to the patient.

10. The phototherapy treatment method of claim 1 , wherein the light source is configured to generate light having a wavelength between approximately 350 nanometers and 550 nanometers.
