弹簧夹针护套
摘要：
本发明提供了一种安装在静脉内导管组件(1000)的导管毂中的弹簧夹针尖屏蔽装置(100)。该弹簧夹针尖屏蔽装置(100)包括有一孔(102)从中延伸穿过的一基板(101)、以及在所述基板(101)上在一连接点(104)处延伸的至少一个弹性臂(103)。所述至少一个弹性臂(103)具有一静止状态，它可由该状态被促使沿处于拉伸状态的所述基板(101)的轴向产生穿过所述孔(102)的自由通道；所述至少一个弹性臂(103)适于当所述弹性臂(103)处于所述静止状态时，夹持针(301)的针尖(304)延伸穿过所述孔(102)。当所述弹性臂(103)处于所述主体的所述静止状态(107)时，任何沿所述基板(101)的所述轴向而纵向延伸穿过所述孔(102)的直虚线，都与所述至少一个弹性臂(103)一致。该弹簧夹针尖屏蔽装置(100)是由一种刚性材料制成的，且其至少一部分被涂有固体润滑剂(106)。本发明也提供安装有这样的屏蔽装置的一导管组件(1000)。
摘要（英）：

A spring clip needle tip shielding device (100) for arrangement in a catheter hub of an intravenous catheter assembly (1000) is provided. The spring clip needle tip shielding device (100) comprises a base plate (101) with a hole (102) extending there through and at least one resilient arm (103) extending at an attachment point (104) at said base plate (101). The at least one resilient arm (103) has a resting state, from which it may be urged to yield free passage through said hole (102) in an axial direction of said base plate (101) in a tension state, said at least one resilient arm (103) being adapted for clamping a needle tip (304) of a needle (301) extending through said hole (102) when said resilient arm (103) is in said resting state. Any straight imaginary line extending longitudinally through said hole (102) in the axial direction of said base plate (101) coincides with said at least one resilient arm (103) when said resilient arm (103) is in said resting state (107) of said body. The spring clip needle tip shielding device (100) is of a rigid material, and at least a part thereof is coated with a solid lubricant (106). A catheter assembly (1000) including such shielding device is also provided.
