Abstract
The present disclosure is directed to a phototherapeutic apparatus for focused UVB radiation and vitamin D synthesis and associated systems methods. In one embodiment a phototherapeutic apparatus can include a housing at least partially defining an irradiation zone, and an ultraviolet (UV) radiation source carried by the housing. The irradiation zone can be configured to accommodate at least a portion of a human patient. The phototherapeutic apparatus can further include a filter between the UV radiation source and the irradiation zone. The filter can be configured to at least substantially remove UV radiation outside of a predetermined spectrum centered at about 297 nm and having a bandwidth of at most 10 nm.
Claims20
A phototherapeutic apparatus, comprising:
- an ultraviolet (UV) radiation assembly comprising:
- a UV radiation source carried by a housing;
- and
- a reflector positioned forward of the UV radiation source to direct the UV energy emitted by the UV radiation source forward toward an irradiation zone, the UV energy contacting the reflector forward of the UV radiation source,
- wherein the UV radiation assembly is configured to emit UV radiation having wavelengths between 290 nm and 310 nm to stimulate vitamin D production in skin;
- and
- a controller communicatively coupled to the UV radiation assembly and configured to cause the phototherapeutic apparatus to limit UV radiation of the phototherapeutic apparatus to less than a user-specific minimum erythemal dose (“MED”) based on a skin tone associated with a user in the irradiation zone by adjusting a duration of an exposure period.
A phototherapeutic apparatus, comprising:
- a housing;
- an ultraviolet (UV) radiation assembly comprising:
- a plurality of light emitting diodes (LEDs) carried by the housing;
- and
- a plurality of reflectors forward of associated ones of the plurality of LEDs to direct UV energy emitted by the plurality of LEDs generally forward toward an irradiation zone;
- and
- a controller communicatively coupled to the UV radiation assembly and configured to cause the phototherapeutic apparatus to limit a duration of an exposure period of a user in the irradiation zone based on a skin type of the user.
A method of delivering ultraviolet (UV) radiation to stimulate vitamin D production via irradiation of skin, the method comprising:
- emitting UV energy with one or more light emitting diodes (LEDs) carried by a housing of a phototherapeutic apparatus;
- directing, via one or more reflectors, the UV energy forward from the one or more LEDs toward an irradiation zone, wherein the UV energy transmitted from the phototherapeutic apparatus to the irradiation zone is within a predefined spectrum between 290 nm and 310 nm;
- terminating the transmission of the UV energy after a user has been exposed to less than a user-specific minimum erythemal dose (“MED”) based on user-specific information.
