Abstract
Sistema de punción para extraer un fluido corporal de la piel de un ser humano o un animal, que comprende unelemento de aguja (3) para pinchar en la piel, un aparato de punción (2) que incluye un accionamiento de punción(15a), por medio del cual se impulsa un movimiento de punción del elemento de aguja (3), que está acoplado alaccionamiento de punción mediante un mecanismo de acoplamiento (28), en dirección de punción, - presentando el aparato de punción (2) una carcasa (4) con una abertura de carcasa (5) en su extremo delantero endirección de punción, y estando la abertura de carcasa (5) rodeada por una superficie de contracto carcasa-piel (7),que en el uso del aparato de punción (2) se presiona contra la piel, - moviéndose el elemento de aguja (3) en una dirección de punción en una fase de avance del movimiento depunción en un recorrido de punción predeterminado hasta que su punta (3c) penetra en la piel para producir unaherida, y retrayéndoselo en una fase de retroceso del movimiento de punción después de alcanzarse un punto deinversión que se corresponde con la profundidad de punción (S) en la piel, - estando previsto para mejorar la reproducibilidad de la profundidad de punción (S), un elemento de referencia deprofundidad de punción (8) con una superficie de referencia de contacto de piel (11), el cual está conformado ydispuesto de tal modo, que la superficie de referencia de contacto de piel (11) se encuentra en contacto con la pielen el punto de inversión del movimiento de punción y el valor predeterminado de la profundidad de punción (S) sedetermina por medio de la distancia, en dirección de punción, que existe en el punto de inversión del movimiento depunción entre la superficie de referencia de contacto de piel (11) y la posición de la punta (3c) del elemento de aguja(3), estando al momento, en que la punta (3c) del elemento de aguja (3) pasa, en la fase de avance del movimientode punción, por la superficie de referencia de contacto de piel (11) y penetra en una superficie de piel que seencuentra en contacto con ésa, el elemento de referencia de profundidad de punción (8) con la superficie dereferencia de contacto de piel (11) en una posición estacionaria definida con respecto al punto de inversión delmovimiento de punción, - estando el elemento de referencia de profundidad de punción (8) conformado y dispuesto de tal modo, que la piel alapretar contra la superficie de referencia de contacto de piel (11) se estabiliza en lo referente a una deformación depiel incidente en la piel durante la punción, - presentando el elemento de aguja (3) un canal capilar (3b), a través del cual puede transportarse un fluido corporalhacia fuera de la piel, - retrayéndose el elemento de aguja, después del punto de inversión del movimiento de punción, en contra de ladirección de punción a una profundidad residual de punción, y - teniendo posteriormente lugar durante una fase colectora para recibir el fluido corporal, un movimiento en comúndel elemento de referencia de profundidad de punción (8) y del elemento de aguja (3) en contra de la dirección depunción antes de que la punta (3c) del elemento de aguja (3) esté completamente extraída de la piel.
