Abstract

La présente invention concerne un dispositif de photothérapie. Le dispositif de photothérapie selon un mode de réalisation comprend : une unité d'irradiation de lumière comprenant une unité source de lumière ; une unité capteur pour capter si l'unité source de lumière est fixée à un corps d'utilisateur ; et une unité corps comprenant une unité de commande pour commander l'unité source de lumière par un signal reçu depuis l'unité capteur. L'unité d'irradiation de lumière comprend : l'unité source de lumière comprenant au moins une source de lumière pour émettre de la lumière pour la photothérapie ; une unité substrat sur laquelle l'unité source de lumière est montée ; et une unité de transmission de lumière recouvrant l'unité source de lumière. Lorsque l'unité d'irradiation de lumière est fixée à un corps d'utilisateur, l'unité de commande peut commander l'unité source de lumière de sorte qu'un site chirurgical est exposé au rayonnement avec une lumière thérapeutique. De plus, lorsque l'unité d'irradiation de lumière est détachée du corps d'utilisateur, l'unité de commande peut commander l'unité source de lumière de sorte que la lumière thérapeutique émise depuis cette dernière soit interrompue.
