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 tubular housing; a needle shield sleeve (20); a syringe carrier mechanism comprising a syringe carrier (36), a syringe (16), a holding member (46), a first activator member (56) , a second activator member (66), a drive mechanism comprising a plunger rod (90) wherein the second activator member (66) comprises flexible tongues (70) having annular inwardly directed ledges (74), wherein the holding member (46) comprises flexible tongues (52) having ledges (54), and wherein the plunger rod (90) comprises a circumferential groove (96) having a mutual shape as that of the ledges (74) of the second activator member (66) and as that of the ledges (54) of the holding member (46) so that the annular inwardly directed ledges (74) of the second activator member (66) and the radial inwardly directed ledges (54) of the holding member fit into the groove (96).

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 ...
