Abstract
An ambulatory device for use in a therapeutic and/or cosmetic treatment, the device comprises an organic light-emitting semiconductor which, in use, covers an area to be treated and emits electromagnetic radiation to cause said therapeutic and/or cosmetic treatment of the area. The light source may be extensive to provide uniform irradiation of the area to be treated and may be pulsed. The device may also include a photopharmaceutical.
Claims15
An ambulatory device for use in photodynamic therapy, the device comprising an electromagnetic radiation source, attachment means for attaching the electromagnetic radiation source to a patient and control means for activating and deactivating the source to cause the latter to emit a succession of light pulses for activating a photodynamic chemical, whilst reducing the effects of photobleaching on the chemical, wherein the succession of light pulses has a period in the range of 20 ms to 2000 s and wherein the electromagnetic radiation source is a single organic light-emitting semiconductor, and wherein the ambulatory device is operated from a battery pack weighing less than 200 g, and wherein the photodynamic chemical is in the form of a photopharmaceutical in a translucent base or a cream which scatters light and which is absorbed into the skin.
