Compact spring inserter for drug delivery infusion set
Abstract:
An infusion set (101) includes a base (111) and an inserter (121) removably connected to the base (111). A catheter (134) is movable from a first catheter position disposed substantially entirely within the inserter (121) to a second catheter position' in which a free end of the catheter (134) is disposed externally of the base (111). An introducer needle (142) is located within the catheter (134) and is movable with the catheter (134) between a first introducer needle position disposed substantially entirely within the inserter (121) and a second introducer needle position in which a free end of the introducer needle (142) is disposed externally of the base (111). A spring member (171) moves the catheter (134) from the first to the second catheter position and the introducer needle (142) from the first to the second introducer needle position to facilitate insertion of the catheter (134). The spring member (171) is disposed substantially entirely within the base (111) when the catheter (134) is in the second catheter position.
Abstract(Chinese):

输液器（101）包括可移除地连接到基座（111）的基座（111）和插入件（121）。 导管（134）可从基本上完全设置在插入器（121）内的第一导管位置移动至第二导管位置，其中导管（134）的自由端设置在基座（111）的外部。 导引针（142）位于导管（134）内并且可以随着导管（134）在基本上完全设置在插入器（121）内的第一引导器针位置和第二引导器针位置之间移动 导引针（142）设置在基部（111）的外部。 弹簧构件（171）将导管（134）从第一导管位置和导引器针头（142）移动到第一导引器针位置到第二导引器针位置，以便于插入导管（134）。 当导管（134）处于第二导管位置时，弹簧构件（171）基本上全部设置在基座（111）内。
