Description

Phototherapy device

Technical Field

The present utility model relates to a device for delivering light-based therapy treatment using light emitting diode ("LED") phototherapy.

Background

Certain spectra are known to be effective in treating various diseases and/or conditions including depression, skin conditions and diseases, cancer, wound healing, retinal disorders, sleep disorders, circadian sleep disorders, and jaundice. Such therapy may be provided in a clinical setting or in a convenient home phototherapy delivery device for use in a subject's home.

Recently, red and near infrared light therapies have become increasingly popular in the treatment of skin conditions and diseases, slow wound healing, muscle atrophy and bone density disorders. Without being bound by theory, red and near infrared light are believed to mimic natural dawn and dusk light, and operate by powering "power plants" in body cells called mitochondria. Like plants, red and near infrared light is thought to be absorbed through the skin and tissues of a subject and converted into cellular energy. By causing the cell energy to surge, the cell can then work more effectively and efficiently.

Red and near infrared light therapy delivery devices are known. However, such devices typically provide only red or near infrared light of a single wavelength or at most two wavelengths (i.e., one red wavelength and one near infrared wavelength).

It should be clearly understood that if a prior art publication is referred to herein, this reference does not constitute an admission that: the publication forms a part of the common general knowledge in the art in australia or in any other country.

The test was performed in two subjects (i.e., subject a and subject B), who tested each device configuration periodically over a period of one week. Both subjects were previously experienced with prior art devices configured to emit red light with a peak wavelength of 630 nm.

The screening results are presented in the table below.

TABLE 2 screening results

A subject	Configuration 2	Configuration 2	Configuration 3	Configuration 4	Configuration 5
						A	5	4	3	2	1
B	5	4	3	1	2

In the table above, each subject has indicated their personal preferences for the device configuration by numbering the configurations in descending order of personal preferences.
