A skin cutter is disclosed for painlessly extracting small blood amounts from human or animal tissue. A blade (13) is made to vibrate by means of an oscillator (14, 32), is slowly lowered into the tissue and withdrawn again. In a first embodiment, the blade vibrates substantially in a parallel direction to the cutting edge of the blade and to the surface of the tissue. In the second embodiment, the blade vibrates substantially in the perpendicular direction to the surface of the tissue. The advantage of the disclosed devices is that the pain caused by pricking is reduced.
L'invention concerne un dispositif pour l'incision de la peau, permettant le prélèvement de petites quantités de sang dans du tissu humain ou animal. Un oscillateur (14, 32) fait vibrer une lame (13), laquelle pénètre avec un mouvement relativement lent dans le tissu puis est retirée de celui-ci. Dans un premier mode de réalisation, la vibration de la lame s'effectue sensiblement parallèlement à l'arête de coupe de la lame et à la surface du tissu. Dans un deuxième mode de réalisation, la vibration de la lame s'effectue sensiblement perpendiculairement à la surface du tissu. Le dispositif selon l'invention est avantageux en ce qu'il permet de réduire la douleur due à la piqûre.
