Abstract

La presente invencion se refiere a un dispositivo cortante de la piel para extraer de manera indolora cantidades pequeñas de sangre del tejido de un ser humano o de un animal. Una hoja (13) se hace vibrar por medio de un oscilador (14, 32), se baja lentamente hacia el tejido y es retirada nuevamente. En una primera modalidad, la hoja vibra substancialmente en una direccion paralela con respecto al borde cortante de la hoja y con respecto a la superficie del tejido. En la segunda modalidad, la hoja vibra substancialmente en la direccion perpendicular con respecto a la superficie del tejido. La ventaja de los dispositivos descritos es que el dolor provocado por la picadura es reducido.
