Embodiment Construction

[0038] As used herein to describe any relative position of the drive mechanism, drug delivery pump, or assembly of the present invention, the terms "axial" or "axially" generally refer to the drive mechanism around which it is disposed as a preferred longitudinal axis "A ”, however not necessarily symmetrical about the longitudinal axis “A”. The term "radial" generally refers to a direction perpendicular to the axis A. The terms "adjacent", "rearward", "rearward", "rearward" or "rearward" generally refer to an axial direction in the direction "P". The terms "distal", "anterior", "forward", "depressed" or "forward" generally refer to an axial direction in the "D" direction. As used herein, the term "glass" should be understood to include other similar non-reactive materials suitable for pharmaceutical grade applications where glass is often required, including but not limited to certain non-reactive polymers such as cyclic olefin copolymers (COC) and cyclic olefin polymer (CO...

Abstract

A drive mechanism (100) with integral status indication includes a drive housing (130), a status switching interconnect (132), a drive biasing member (122), a piston (110), and a punctureable Drug container (50) through seal (56), syringe (58) and plunger seal (60), wherein the drive bias member (122) is configured to press against the interface surface of piston (110) (110C) on. The drive mechanism (100) may comprise an incremental state rod (650) having a rod interconnect (652), wherein the rod (650) resides within the drive housing (630) and piston (610), and wherein the rod (650 ) has an interconnect that engages one or more contacts on the piston (610) to provide incremental feedback. The drug delivery pump (10) with integrated status indication includes a housing (12) and an assembly platform (20), on which an activation mechanism (14), an insertion mechanism (200), and a fluid channel can be installed A connecting piece (300), a power supply and a control system (400), and a driving mechanism (100) with a medicine container (50).

Description

[0001] Cross-reference to related applications [0002] This application claims priority to US Provisional Application No. 61 / 530,788, filed September 2, 2011, the contents of which are incorporated herein by reference in their entirety. technical field [0003] The present invention relates to drug delivery pumps. More particularly, the present invention relates to a drive mechanism with integrated status indication, a drug delivery pump with a status integrated drive mechanism, and methods of operating said devices, and methods of assembling said devices. Background technique [0004] Parenteral delivery (ie, delivery other than through the digestive tract) of various drugs has become the desired method of drug delivery for a number of reasons. This form of drug delivery via injection enhances the effect of the delivered substance and ensures that the unchanged drug reaches the desired site in effective concentrations. Likewise, undesired side effects associated with oth...
