ULTRAVIOLET PHOTOTHERAPY DEVICE AND ULTRAVIOLET IRRADIATION METHOD FOR ULTRAVIOLET PHOTOTHERAPY DEVICE

WIPO Patent Application WO/2023/181488

A1

The present invention is an ultraviolet phototherapy device (1) comprising: a plurality of LEDs that emit light including ultraviolet light; a light-emitting surface that emits the light from the LEDs; a control unit (45) that divides the LEDs into a plurality of blocks and controls the lighting of each of the LEDs for each block; an input unit (41) for inputting a set irradiation dose which is the irradiation dose of therapeutic light with which a patient is to be irradiated when reference light emitted from a reference light source is used as therapeutic light; and a recording unit (43) that records a parameter for correcting the set irradiation dose for each block. The control unit (45) comprises a correction unit (53) for correcting the set irradiation dose input by the input unit (41) for each block on the basis of the parameters recorded by the recording unit (43), and a lighting control unit (54) whereby the LEDs are lit in each block so that the irradiation doses of light become the set irradiation doses after correction thereof by the correction unit. The corrected set irradiation doses are irradiation doses derived on the basis of the impact of the reference light on the human body and the impact of the light emitted from the light-emitting surface on the human body.
