Abstract

L'invention concerne un ensemble aiguille (10, 110, 210, 210', 310, 410, 610) qui peut prélever un échantillon de matière biologique dans une aiguille (14, 114, 214, 214', 314, 414, 614, 766, 820, 840, 850) de l'ensemble. L'ensemble aiguille comprend un écran de sûreté (16, 116, 216, 216', 316, 416, 516, 616, 769, 801, 821, 832, 832', 916) pouvant être déplacé sur l'ensemble aiguille afin de couvrir une pointe acérée (28, 428, 628) de l'ensemble aiguille. L'écran peut être bloqué au-dessus de la pointe acérée au moyen d'un mécanisme de verrouillage (52, 152, 252, 252', 352, 452, 552, 652, 760, 814, 952). L'ensemble comprend également un obturateur (26, 126, 226, 226', 326, 426, 526, 626, 761, 791, 803, 813, 823, 831, 831') qui peut être inséré dans l'aiguille afin de retirer l'échantillon de l'aiguille. Un élément de réarmement (72, 172, 272, 272', 372, 482, 582, 672, 762, 817, 847, 861, 972), qui, dans certains modes de réalisation est associé à l'obturateur, est capable d'entrer en contact de manière fonctionnelle avec le mécanisme de verrouillage afin de libérer le mécanisme de verrouillage et de permettre à ce dernier de s'éloigner de la pointe acérée.
