Abstract
Procédé et appareil de perçage au laser d'un orifice de distribution (37) dans un distributeur (30) d'un agent pharmaceutique. Un distributeur (30) possède un compartiment (32) formé par une paroi (31) et destiné à contenir un agent pharmaceutique (33) à distribuer. Un faisceau laser est employé pour brûler au moins en partie la paroi (31). Ledit faisceau laser et le distributeur (30) sont placés l'un par rapport à l'autre de telle manière que le faisceau laser soit orienté vers un site (35) d'orifice prédéterminé sur le distributeur (30). Ledit faisceau laser est éteint (désexcité) pendant la période de positionnement. Le faisceau laser est ensuite excité et déplacé par rapport au distributeur (30) pour tracer un orifice de distribution (37) à proximité du site (35) de l'orifice. Pendant le mouvement de traçage, le faisceau laser se déplace depuis le site (35) d'orifice le long d'une trajectoire (37). De préférence, la trajectoire (37) est fermée. Le mouvement de traçage permet au faisceau laser de brûler la paroi (31) en décrivant l'orifice de distribution (37). Le mouvement de positionnement et le mouvement de traçage sont commandés par un système de balayage (16). La source laser (13) est excitée pendant le mouvement de traçage afin de brûler la paroi (31) et d'y former un orifice de distribution (37) en vue de la distribution ultérieure de l'agent pharmaceutique (33) par ledit orifice.
