摘要：
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.
