CA 2625159

The present invention relates to lancet device (1), by which a lancet (10) is displaceable along a piercing path to generate a piercing wound in a skin surface, in particular to obtain bodily fluid for diagnostic purposes. To achieve performance of a piercing movement which is low in noise and shock, it is suggested that the lancet drive (2) comprise a control unit for regulating the piercing depth of the lancet (10) and the lancet (10) preferably be implemented to oscillate freely out in the piercing direction without delimitation by a mechanical piercing depth stop.

La présente invention porte sur un dispositif à lancette (1), dans lequel la lancette (10) peut se déplacer le long d'une glissière afin de percer la peau en surface, en particulier dans le but d'obtenir un liquide biologique à des fins de diagnostic. Afin de réaliser un perçage peu bruyant et sans heurt, il est proposé que le mécanisme d'entraînement de la lancette (2) comprenne une unité de commande permettant de réguler la profondeur du perçage réalisé par la lancette (10) et que la lancette (10) puisse, de préférence, osciller librement dans l'axe du mouvement du perçage sans être restreint par un mécanisme d'arrêt définissant la profondeur du perçage.
