Embodiment Construction

[0036] In this application, the term "distal portion / end" refers to the part / end of a device, or part / end of a member of a device, which is furthest away from the delivery site of the patient when the device is in use. far away. Correspondingly, the term "proximal portion / proximal end" refers to the portion / end of the device, or of a member of the device, which is at the closest position away from the delivery site of the patient when the device is in use .

[0037] A drug delivery device, such as the autoinjector seen in FIG. 1 , comprises a generally elongated tubular housing having opposed proximal 10 and distal 12 portions. The proximal end 10 of the housing is provided with an elongated opening 14 for viewing a syringe 16 containing a fluid medicament, such as figure 2 shown. The distal portion is provided, for example on its inner surface, with an annular recess adapted to interact with corresponding engagement means, eg on the proximal outer surface of the proximal ...

Abstract

The present invention relates to a medicament delivery device comprising a generally elongated tubular housing having opposite proximal (10) and distal (12) parts, a needle shield sleeve (20) slidably and coaxially arranged inside the housing and wherein a proximal part of said sleeve protrudes a distance outside the proximal part of the housing; a syringe carrier mechanism comprising a syringe carrier (36) slidably and coaxially arranged within the needle shield sleeve, a syringe (16) comprising a stopper (92), a medicament and a needle, wherein said syringe is coaxially arranged within said syringe carrier, and a holding member (46) connected to the syringe carrier; a first activator member (56) and a second activator member (66); a drive mechanism wherein said drive mechanism is adapted to accumulate a drive force for moving said syringe carrier mechanism in a first step and a second step and wherein said second activator member (66) is arranged with information means for producing audible, visual and / or tactile feedback to a user about a completed injection.

Description

technical field [0001] The present invention relates to drug delivery devices, and in particular to devices capable of providing information about completed drug delivery steps. Background technique [0002] There are several devices on the market which are capable of delivering doses of medicaments automatically or semi-automatically, wherein these devices comprise several interacting components for achieving the desired function. [0003] One type of such delivery device is a syringe capable of delivering doses of a medicament, with functions such as penetrating the skin of a patient and subsequently injecting the medicament. One such device is disclosed, for example, in document EP1349590, comprising an actuation member in the form of a button arranged on its distal end. The button may only actuate the mechanism if the front end of the device is pressed against the injection site. When this is done and the button is pressed, the penetration mechanism within the syringe ...
