摘要:
Instrument for producing a sample of body fluid for analysis by piercing the skin with a lancet cutting element (12) that has a skin piercing tip (7), said instrument (11) having - a housing (13), - a lancet cutting drive (14) inside said housing (13) for driving a lancet cutting element (12) connected thereto in a puncture movement in which the lancet cutting element (12 ) moves, after triggering the puncture movement, in a direction 10 of the puncture until it reaches a point (P) of maximum displacement and in an inverse direction after it has reached the point (P) of maximum displacement, - a pressure ring (1) that surrounds a skin contact hole (4) and that is adapted to be pressed against the skin such that the skin (3) bulges inside the hole (4) to promote the extraction of fluid from the body, characterized p The skin contact opening has an opening area corresponding to a circle with a diameter of at least 3 mm and at most 8 mm, and the instrument comprises a pressure force control device (37) for controlling the pressure force between the pressure ring (1) and the skin (3) at the time of firing the puncture movement so that it is at least 3 N and at most 8 N.Instrumento par producir una muestra de líquido corporal para análisis perforando la piel con un elemento de corte con lanceta (12) que tiene una punta de perforación de la piel (7), teniendo dicho instrumento (11) - un alojamiento (13), - un accionamiento de corte con lanceta (14) en el interior de dicho alojamiento (13) para el accionamiento de un elemento de corte con lanceta (12) conectado al mismo en un movimiento de pinchazo en el cual el elemento de corte con lanceta (12) se mueve, después del disparo del movimiento de pinchazo, en una dirección 10 del pinchazo hasta que llega a un punto (P) de desplazamiento máximo y en un sentido inverso después de que haya llegado al punto (P) de desplazamiento máximo, - un anillo de presión (1) que rodea un orificio de contacto con la piel (4) y que está adapta
