    • A retractable needle assembly, as shown in Figure 1, for use with a catheter (25), featuring a cylindrical hub (2) having a hollow needle (1) extending through the hub (2). The hub (2) has a flash chamber (3) connected thereto where the interior of the needle (1) is in fluid communication with the interior of the flash chamber (3). The hub (2) is slidably positioned in a housing (15) as shown in Figure 7a, having a wall with a longitudinal slot (20) therein. A stem (7) having a thumbrest (8) rigidly affixed thereto is connected to the hub (2) and passes through the slot (20) of the housing, where the thumbrest (8) may be used to manually move the stem (7) from a first locking position (20b) where the needle (1) is exposed, to a second locking position (20d) where the needle (1) is retracted within the housing (15). Also disclosed are blood-drawing needles, as shown in Figure 3, comprising a similar cylindrical hub (2) with a stem (7) affixed thereto and having a hollow needle (1) extending from one end of the hub (2). The hub (2) has a cavity (9) adapted to frictionally engage the tip of a syringe barrel on its other end. These blood-drawing needles are longitudinally reciprocable in a manner identical to the needle assembly above.
    • 如图1所示的可伸缩针组件,用于与导管(25)一起使用,其特征在于具有延伸穿过毂(2)的中空针(1)的圆柱形毂(2)。 轮毂(2)具有连接到其上的闪光室(3),其中针(1)的内部与闪光室(3)的内部流体连通。 轮毂(2)可滑动地定位在如图7a所示的壳体(15)中,其具有在其中的纵向狭槽(20)的壁。 具有刚性地附接到其上的拇指托架(8)的杆(7)连接到轮毂(2)并穿过壳体的狭槽(20),其中拇指(8)可用于手动地移动杆(7 )从针(1)暴露的第一锁定位置(20b)移动到针(1)在壳体(15)内缩回的第二锁定位置(20d)。 还公开了如图3所示的抽血针,其包括类似的圆柱形轮毂(2),其具有固定到其上的杆(7)并且具有从轮毂(2)的一端延伸的中空针(1)。 轮毂(2)具有适于在其另一端摩擦地接合注射器筒的尖端的空腔(9)。 这些抽血针可以以与上述针组件相同的方式纵向往复运动。
