Abstract: A safety blood collection device including holder housing adapted to maintain a needle cannula with a puncture tip extending from a forward end thereof and to receive a sample collection tube through a rearward end thereof. A retainer coacts with the holder housing to maintain the needle in a first position with the puncture tip of the needle extending from the forward end of the holder housing. The retainer is adapted for activation so as to release the needle from this first position, thereby permitting the needle to move based on the force of gravity and the weight of the needle to a second position in which the puncture tip of the needle cannula is contained within the interior chamber of the holder housing. As such, upright placement of the holder housing upon activation of the retainer will permit the needle to drop within the holder housing, thereby containing the needle cannula therein as a self-contained assembly.

Abstract translation: 一种安全采血装置，包括保持器壳体，该保持器壳体适于维持具有从其前端延伸的穿刺末端的针插管，并且通过其后端接收样品收集管。 保持器与保持器壳体共同作用以将针保持在第一位置，其中针的穿刺尖端从保持器壳体的前端延伸。 保持器适于致动以便从该第一位置释放针，由此允许针基于重力和针的重量移动到其中包含针插管的穿刺尖端的第二位置 在保持器壳体的内部腔室内。 因此，保持器壳体在保持器启动时的直立放置将允许针头落入保持器壳体内，从而将针管插入其中作为独立组件。
