Embodiment Construction

[0103] When terms such as "up" and "down", "right" and "left", "horizontal" and "vertical", "clockwise" and "counterclockwise" or similar relative expressions are used hereinafter, these are only Refers to drawings rather than actual usage. The figures shown are schematic representations, therefore, the configuration of the various structures and their relative dimensions are for illustrative purposes only.

[0104] In this context, it is convenient to define the term "distal end" in the figures to refer to the end of the injection device that holds the needle cannula during injection and is directed towards the user, while the term "proximal end" refers to the opposite end, as in Figure 2A -B shown. Distal and Proximal mean along the axial orientation extending along the longitudinal axis (X) of the injection device, also as Figures 2A-2B published in.

[0105] When referring to clockwise and counter- or counter-clockwise in the following examples, it is understood that ...

Abstract

The present invention relates to a preloaded injection device having a non-removable cartridge embedded in a housing structure, and wherein a piston rod drive mechanism comprises a threaded piston rod that moves helically in a nut fixed to the housing structure. During assembly of the injection device, the air gap between the plunger and the piston rod arrangement in the cartridge may be eliminated by axially moving a nut element of the drive mechanism during assembly. In an alternative solution, the piston rod includes a telescoping element that is axially slidable relative to the piston rod to achieve a zero position.

Description

technical field [0001] The present invention relates to a prefilled injection device for delivering a liquid drug, preferably in the form of one or more doses of the liquid drug. The invention particularly relates to injection devices in which the distance between the piston rod, which moves the plunger forward inside the container, and the plunger itself, has been minimized during assembly of the injection device. [0002] In a second aspect, the present invention relates to a method for assembling such an injection device. [0003] Furthermore, the present invention relates to an alternative solution and a method for implementing the alternative solution. Background technique [0004] Injection devices are well known and used to treat many different diseases, especially in the field of diabetes. A very popular type of injection device is the so-called disposable or prefilled injection device. Injection devices of this type generally comprise a cartridge containing a pre...
