摘要： A phototherapy device 1 includes a laser light source 8 for emitting laser light at a target portion T, a limit switch 10 for detecting an approach of the laser light source 8 to a target portion T up to a predetermined distance and outputting a proximity signal, and an optical sensors 7 for detecting a distance to the target portion T and outputting a distance signal S corresponding to the distance and is configured so that a reference value L0 is set based on the distance signal S detected after the proximity signal is detected and emission of laser light by the laser light source 8 is permitted in accordance with an amount of fluctuation of the distance signal S with respect to the reference value L0.

摘要： An object of the present invention is to provide a chair-type phototherapy device that enables a patient to perform light irradiation accurately targeted at a treatment site in a seated position on a chair and consequently achieves effective phototherapy even when the treatment site is in the back region that the patient is unable to see, for example, as in light irradiation for dysuria patients and patients with pain, and the patient performs light irradiation by himself/herself at home. The present invention provides a chair-type phototherapy device having a seat on which a patient is seated. The chair-type phototherapy device includes a radiation module configured to emit radiation light toward a living body, a drive module positioned behind the patient for moving the radiation module, and a fixing module fixing the drive module to the seat.
