Abstract

L'invention concerne un dispositif stimulateur de croissance capillaire (10, 11, 12, 13, 14) utilisant de la lumière, ledit dispositif stimulateur de croissance capillaire comportant une unité (20) d'irradiation servant à irradier la peau à l'aide d'une lumière en proche infrarouge et une unité (90, 100) de mesure du débit sanguin servant à mesurer la quantité de sang circulant sous la peau irradiée par la lumière en proche infrarouge. Au moyen du présent dispositif stimulateur de croissance capillaire utilisant de la lumière, l'irradiation par la lumière en proche infrarouge est réalisée simultanément à la mesure du débit sanguin en tirant parti du phénomène selon lequel l'irradiation par la lumière en proche infrarouge provoque une augmentation du débit sanguin dans la peau ainsi irradiée. Il est ainsi possible de percevoir si le site d'irradiation est ou non irradié de façon adéquate par la lumière en proche infrarouge. De ce fait, le site d'irradiation peut être efficacement irradié par la lumière en proche infrarouge et, par conséquent, la croissance capillaire peut être stimulée.
