    Abstract: A needle assembly includes a transparent or translucent housing with a fluid inlet and outlet end, a flashback chamber, and a venting mechanism therebetween. The venting mechanism includes a blocking member to control the fluid flow in the venting mechanism so that it flows along the longest path through the vent. Substantially axially aligned inlet and outlet cannulas extend from the housing and communicate with the chamber. A sealable sleeve covers the external end of the outlet cannula. Relative volumes of the cannulas, the chamber, and the sleeve are selected to provide rapid reliable flashback indicative of venous entry with an internal vent positioned within the housing to divide the interior into first and second chambers, with the second chamber being adapted to maintain a negative pressure therein relative to the external environment so as to inhibit leakage of blood from the needle tip on withdrawal from the patient.

    Abstract translation: 针组件包括具有流体入口和出口端的透明或半透明壳体，闪回室以及它们之间的排气机构。 排气机构包括阻挡构件以控制通气机构中的流体流动，使得其沿着最长路径流过通气孔。 基本上轴向对准的入口和出口插管从壳体延伸并与腔室连通。 可密封套筒覆盖出口插管的外端。 插管，腔室和套管的相对体积被选择以提供指示静脉入口的快速可靠闪回，其中位于壳体内的内部通气口将内部分隔成第一和第二腔室，第二腔室适于维持 相对于外部环境的负压，以便在从患者身体拔出时抑制血液从针尖泄漏。

    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。
