A blood sampling device is provided with a housing (12), a lancet assembly (30), a lancet holder (36) disposed in the housing for supporting the lancet assembly (30), the lancet holder (36) being movable in a lancing direction between a cocked position and a puncture position, a drive spring (42) for forcing the lancet holder (36) from the cocked position to the puncture position, and a mechanism for damping movement of the lancet holder (36) during travel of the lancet holder (36) from the puncture position to an intermediate position between the puncture position and the cocked position. The damping mechanism may be provided in the form of a non-planar surface, such as a corrugated surface (70), disposed on the lancet holder (36) and a damping member which makes contact with the non-planar surface during movement of the lancet holder (36).
Dispositif pour ponction veineuse comportant un boîtier (12), un ensemble lancette (30), un porte-lancette (36) situé dans la boîtier pour supporter la lancette (30), le porte-lancette (36) pouvant être déplacé axialement entre une position retirée et une position avancée, un ressort moteur (42) servant à forcer le porte-lancette de la position retirée à la position avancée et un mécanisme pour amortir le mouvement du porte-lancette (36) pendant le déplacement du porte-lancette de la position retirée à une position intermédiaire entre la position avancée et la position retirée. Le mécanisme amortisseur peut prendre la forme d'une surface non plane, comme une surface ondulée (70), placée sur le porte-lancette (36) et un élément amortisseur qui entre en contact avec la surface non plane pendant le déplacement du porte-lancette (36)
