Embodiment Construction

[0022] Figure 1 to Figure 7 The first embodiment shown in includes a drug container holder 10 having a generally tubular elongated body 12, as figure 1 shown. In this regard, it is understood that the drug container holder may also or alternatively be part of the housing of the drug delivery device. The drug container holder 10 is arranged to receive a generally tubular elongated drug container 14 . The medicament container 14 is arranged with a stopper 16 which is movable within the medicament container 14, for example by a plunger rod acting from the distal direction. The proximal end of the drug container 14 is provided with an annular shoulder 18 which transforms into a neck 20, such as figure 2 shown. The neck 20 then transitions into a flange portion 22 surrounding a central channel 24 . A septum 26 is positioned to cover the central channel, the septum 26 being made of a material that can be pierced by the sharp distal end of an injection needle, such as a rubber...

Abstract

The invention relates to a medicament container holder (10) for securing a medicament container (14) comprising a generally tubular body provided with a proximally directed neck (20) and a flange part (22), the flange part (22) is provided with a pierceable septum (26); 22) interacting to prevent the drug container (14) from moving in the distal direction; the drug container holder (10) includes mechanical fixation elements (52, 54; 60, 64) configured to engage with the convex The flange portion (22) interacts for pushing the flange portion (22) against the holding element (48) in the distal direction; the drug container holder (10) includes a member for drug delivery (40) ), wherein the mechanical fixation element (52, 54; 60, 64) is configured to engage the drug delivery member (40) when attached to the attachment element (38), so that A force is exerted on said flange portion (22) in the distal direction.

Description

technical field [0001] The present invention relates to a device for a drug container, in particular to a drug container holder for use as part of a drug delivery device. Background technique [0002] Most drug delivery devices are arranged with some kind of drug container which holds the drug to be delivered to the patient. Usually, the drug container is releasably placed in the drug delivery device, especially if the drug delivery device is a so-called reusable device, which is used several times and where an empty drug container is replaced by a new full drug container. [0003] The drug container is usually held inside the drug delivery device to avoid rattling of the drug container, but also to handle forces exerted on the drug container, for example by a plunger rod that is energized during dose delivery. In many cases, the drug container is placed in a dedicated drug container holder within the drug delivery device. This may be the case, for example, if the drug del...
