Abstract

La présente invention concerne un ensemble siège d'aiguille pour un dispositif de collecte de sang sous vide de type à seringue qui comprend une aiguille de ponction vasculaire (11), un siège d'aiguille de ponction (13), une canule d'aiguille de collecte de sang (12), un siège d'aiguille de collecte de sang (14), et un tube de raccordement souple (15). Le siège d'aiguille de ponction (13) est positionné au niveau d'une extrémité avant d'une chambre dans une seringue (3) du dispositif de collecte de sang sous vide, le siège d'aiguille de collecte de sang (14) est fixement raccordé à la seringue (3), et une extrémité arrière de la canule d'aiguille de collecte de sang (12) et la plupart de la canule s'étendent vers l'arrière et sont interposées dans un bouchon de tube d'un tube de collecte d'échantillon de sang (2) de la seringue (3). Une extrémité du tube de raccordement souple (15) est fixement raccordée au siège d'aiguille de ponction (13), l'autre extrémité est fixement raccordée au siège d'aiguille de collecte de sang (14), et le cœur du tube de raccord souple (15), comme une chambre étanche, est en communication avec une cavité du siège d'aiguille de ponction (12) et une cavité (142) du siège d'aiguille de collecte de sang (14). Lors de la réalisation de l'opération d'insertion du tube de collecte d'échantillon de sang (2) dans la seringue, une force opérationnelle transférée du tube de collecte de sang (2) est transférée à la seringue (3) par le siège d'aiguille de collecte de sang (14) parce que le siège d'aiguille de collecte de sang (14) est fixement raccordée à la seringue (3). La flexibilité du tube de raccordement souple (15) assure que la force opérationnelle n'est pas transférée au siège d'aiguille de ponction (13) ou à l'aiguille de ponction vasculaire (11). En résultat, la force opérationnelle transférée du tube de collecte d'échantillon de sang (2) n'a pas d'impact sur l'aiguille de ponction vasculaire (11).
