The invention relates to a device for protecting a skin area against light when detecting and/or treating skin disorders, especially cancer and its preliminary stages, including application of compounds and/or compositions to the skin, in connection with which a photoreactive substance appears in the skin area. The device comprises an opaque foil (1) forming a cavity (4) relative to the skin and having edges (3) engaging the skin, the width of the edges (3) being determined by formula (I), wherein m = the width of the edge, .delta. = the penetration depth of the light in the skin, ln = the natural logarithm, t = the time of the effect of the light, I0 = the luminous intensity at the skin surface, and Ddiffused = the diffused energy dose which is allowed to reach the skin area concerned.
L'invention concerne un dispositif pour la protection d'une région de la peau contre la lumière lors de la détection et/ou du traitement de maladies de la peau, en particulier du cancer et de ses stades préliminaires, cette détection ou ce traitement se faisant par application de composés et/ou de compositions sur la peau entraînant l'apparition d'une substance photoréactive dans ladite région de la peau. Le dispositif comprend un film opaque (1) formant une cavité (4) par rapport à la peau et présentant des bords (3) venant en contact avec la peau, la largeur de ces bords (3) étant déterminée selon la formule (I). Dans ladite formule: m = la largeur du bord; .delta. = la profondeur de pénétration de la lumière dans la peau; ln = le logarithme naturel; t = le temps de l'effet de la lumière; I¿0? = l'intensité lumineuse à la surface de la peau; et D¿diffused? = la dose d'énergie diffusée admissible pour la région de peau concernée.
