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 (20)

1. A phototherapy treatment apparatus comprising:

a bed including (i) at least one of a transparent or a translucent material, (ii) a surface having a plurality of microstructures, and (iii) a plurality of side surfaces;

a housing holding the bed;

a light source supported by the housing, the light source being positioned in the housing so that the light generated by the light source is directed at one of the plurality of the side surfaces and is transmitted through the transparent or translucent material of the bed and through the plurality of microstructures such that the light exits the plurality of microstructures having a more diffusive distribution;

a control unit configured to control the light source to perform a treatment of an ailment when a patient is lying on the bed; and

a plurality of sensors each in communication with the control unit to provide feedback to the control unit at least during performance of the treatment.

2. The phototherapy treatment apparatus of claim 1 , wherein the plurality of sensors are configured to monitor at least one of temperature, air flow, voltage, humidity, or current.

3. The phototherapy treatment apparatus of claim 1 , wherein the light source includes a plurality of light emitting diodes (LEDs) and the control unit is configured to monitor and adjust output characteristics of the plurality of LEDs during performance of the treatment.

4. The phototherapy treatment apparatus of claim 1 , wherein the light source is configured to deliver wavelength capable of treating at least one of psoriasis, bipolar disorder, eczema, or seasonal affective disorder.

5. The phototherapy treatment apparatus of claim 1 , further comprising a heat source configured to be controlled by the control unit to control a temperature of the apparatus.

6. The phototherapy treatment apparatus of claim 1 , further comprising a gooseneck light configured to be used in conjunction with the light source.

7. The phototherapy treatment apparatus of claim 6 , wherein the gooseneck light is configured to output infrared heat.

8. The phototherapy treatment apparatus of claim 1 , wherein the surface is a top surface, and the bed includes an incident surface, and wherein the light source and the incident surface are positioned in the housing such that the light generated by the light source is directed at the incident surface at an angle so as to produce total internal reflection of the light transmitted through the bed.

9. The phototherapy treatment apparatus of claim 1 , which includes a heat sink supported by the housing, the heat sink contacting the light source so as to dissipate heat generated by the light source.

10. The phototherapy treatment apparatus of claim 1 , wherein the bed includes a reflective material constructed and arranged to enhance reflection of the light transmitted through the material of the bed.

11. The phototherapy treatment apparatus of claim 1 , wherein the surface of the bed defines channel that concentrates the light that exits the plurality of microstructures to increase an area of a patient body exposed to the light when the patient is lying on the bed.

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

13. The phototherapy treatment apparatus of claim 1 , wherein the control unit includes a display for displaying one or more of (i) temperature, (ii), treatment time, (iii) pulse rate, (iv) respiratory rate, or (v) intensity of the of light output by the light source.

14. The phototherapy treatment apparatus of claim 1 , wherein the control unit is in wired or wireless communication with the phototherapy treatment apparatus and configured to communicate via a cloud connection to effectuate remote monitoring or control of the phototherapy treatment apparatus.

15. The phototherapy treatment apparatus of claim 1 , wherein the surface having the plurality of microstructures defines an average roughness between approximately 1 micrometer and approximately 20 micrometers.
