    • A drive mechanism (100) having integrated status indication includes a drive housing (130), a status switch interconnect (132), a drive biasing member (122), a piston (110), and a drug container (50) having a cap (52), a pierceable seal (56), a barrel (58), and a plunger seal (60), wherein the drive biasing member (122) is configured to bear upon an interface surface (110C) of the piston (110). Drive mechanism (100) may include an incremental status stem (650) having a stem interconnect (652), wherein the stem (650) resides within the drive housing (630) and the piston (610), and wherein the stem (650) has an interconnect which engages one or more contacts on the piston (610) to provide incremental feedback. A drug delivery pump (10) with integrated status indication includes a housing (12) and an assembly platform (20), upon which an activation mechanism (14), an insertion mechanism (200), a fluid pathway connection (300), a power and control system (400), and the drive mechanism (100) having a drug container (50) may be mounted.
    • 具有集成状态指示的驱动机构(100)包括驱动外壳(130),状态开关互连(132),驱动偏置构件(122),活塞(110)和 (52),可刺穿的密封件(56),筒(58)和柱塞密封件(60)的药物容器(50),其中所述驱动偏置构件(122)构造成承载界面表面 110C)。 驱动机构100可以包括具有阀杆互连652的增量状态阀杆650,其中阀杆650位于驱动器壳体630和活塞610内, 具有接合活塞(610)上的一个或多个触点以提供增量反馈的互连。 具有集成状态指示的药物输送泵(10)包括壳体(12)和组装平台(20),在该组装平台上设置有激活机构(14),插入机构(200),流体路径连接(300), 动力和控制系统(400)以及具有药物容器(50)的驱动机构(100)可以被安装。

    • An insertion mechanism (200) for a drug pump (10) includes an insertion mechanism housing (202); a manifold guide (220); an insertion biasing member (210) initially held in an energized state; a retraction biasing member (216) and a hub (212) connected to a proximal end of a needle (214), wherein the retraction biasing member (216) is held initially in an energized state between the hub (212) and the manifold guide (220); and a manifold (240) having a septum (230) and a cannula (234), wherein the annular space between the septum (230) and the cannula (234) defines a manifold header (242). The needle (214) and cannula (234) are inserted into the body of a user by the insertion biasing member(s) (210), after which only the needle (214) is retracted. Retraction of the needle (214) may open a fluid pathway from the manifold header (242) to the body through the cannula (234). A drug delivery pump (10) includes an activation mechanism (12), a drive mechanism (100), a fluid pathway connection (300), and the insertion mechanism 200. Assembly and operation methods are provided.
    • 一种用于药物泵(10)的插入机构(200)包括插入机构壳体(202); 歧管引导件(220); 最初保持在通电状态的插入偏置构件(210) 回缩偏压构件(216)和连接到针(214)的近端的毂(212),其中回缩偏压构件(216)初始地保持在轮毂(212)和歧管引导件 (220); 和具有隔膜(230)和套管(234)的歧管(240),其中隔膜(230)和套管(234)之间的环形空间限定歧管集管(242)。 针(214)和套管(234)通过插入偏置构件(210)插入使用者的身体中,之后只有针(214)缩回。 针(214)的缩回可以打开通过套管(234)从歧管集管(242)到身体的流体路径。 药物输送泵(10)包括启动机构(12),驱动机构(100),流体通路连接(300)和插入机构200.提供了组装和操作方法。
