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.
Claims36
A phototherapeutic apparatus, comprising:
- a housing at least partially defining an irradiation zone, wherein the irradiation zone is configured to accommodate at least a portion of a human patient;
- an ultraviolet (UV) radiation source carried by the housing;
- and
- a filter between the UV radiation source and the irradiation zone, the filter being configured to at least substantially remove UV radiation outside of a predetermined spectrum, wherein the predetermined spectrum has a bandwidth of at most 10 nm and is centered at about 297 nm.
The phototherapeutic apparatus of 1 wherein the filter comprises a coated glass substrate.
The phototherapeutic apparatus of 1, further comprising a user interface configured to receive user inputs related to parameters that affect vitamin D synthesis in the human patient.
The phototherapeutic apparatus of 14 wherein the user interface is configured to receive feedback from a user regarding a previous phototherapy session provided by the phototherapeutic apparatus or a remote phototherapeutic apparatus communicatively coupled thereto.
A phototherapeutic apparatus, comprising:
- a housing at least partially enclosing a space, wherein the space is configured to accommodate at least a portion of a human body;
- and
- a focused ultraviolet-B (UVB) radiation assembly directed generally toward the space, wherein the focused UVB radiation assembly is configured to deliver UVB radiation focused generally at about 297 nm, and wherein the UVB radiation assembly is configured to stimulate at least 20,000 IU of vitamin D production in human skin during an exposure period of less than 2 minutes.
A method of delivering focused ultraviolet radiation with a phototherapeutic apparatus, the method comprising:
- transmitting ultraviolet rays generally toward an irradiation zone defined by a housing;
- at least substantially filtering the ultraviolet rays outside of a predetermined spectrum, wherein the predetermined spectrum is centered at about 297 nm;
- and
- terminating the transmission of the ultraviolet rays after 5 minutes or less.
A method of providing vitamin D phototherapy, the method comprising:
- providing a phototherapeutic apparatus having an irradiation zone with a focused ultraviolet-B (UVB) radiation assembly directed toward irradiation zone;
- generating UV rays focused at least substantially within a predetermined spectrum via the focused UVB radiation assembly, wherein the predetermined spectrum is within about 290-306 nm;
- and
- delivering a dose of vitamin D to a human patient in the irradiation zone within a predetermined exposure time, wherein the vitamin D is produced in portions of skin of the human patient.
A computer readable medium for controlling a phototherapeutic apparatus, the computer readable medium having instructions for causing the phototherapeutic apparatus to perform a method comprising:
- generating ultraviolet (UV) rays focused at least substantially within a predetermined spectrum via a UV radiation source directed toward an irradiation zone of the phototherapeutic apparatus, wherein the predetermined spectrum is generally focused at about 297 nm;
- and
- delivering a dose of vitamin D to a user in the chamber within a predetermined time period.
