Phototherapy apparatus

A phototherapy apparatus comprising:

• a treatment site detection unit detecting a treatment site;
• a treatment unit comprising:
• a first moving unit movable in a first direction;
• a second moving unit movable in a second direction different from the first direction;
• a body mounted on the first moving unit;
• a light source unit comprising multiple light sources that emit therapeutic light;
• and
• a controller controlling operation of the first moving unit, the second moving unit, and the light source unit, the controller configured to control:
• upon detection of the treatment site with the treatment site detection unit, the first moving unit in the first direction to bring the light source unit into contact with the treatment site and the second moving unit in the second direction to position the treatment unit over the treatment site in response to the treatment site signal;
• upon determination that a distance between the light source unit and the treatment site is less than a predetermined threshold, the light source unit positioned at the treatment site to emit the therapeutic light;
• and,
• wherein the body of the treatment unit is deformable in response to pressure and upon release of the pressure, is returned to an original shape.

A phototherapy apparatus comprising:

• a treatment site detection unit comprising a first detection unit and a second detection unit, the first detection unit comprising a first measurement light source and a first light receiving source and configured to detect a location and an extent of a wound site, and
• the second detection unit comprising a second measurement light source and a second light receiving source and configured to detect an infectious agent present in the wound site by excitation of incident light;
• wherein the first light receiving source and the second light receiving source operate to receive light having different wavelengths;
• a treatment unit comprising a moving unit, a body and a light source unit including one or more light sources;
• a controller configured to control:
• the first detection unit to detect the wound site by controlling the moving unit;
• the second detection unit to detect an infected site in the wound site;
• and
• the light source unit such that the one or more light sources corresponding to location of the infected site emit light targeting the infected site.
