Embodiment Construction

[0035] As should be noted, in this application, when the term "distal part / end" is used, this refers to the part / end of the delivery device or its components which is located furthest from the drug delivery site of the patient. Accordingly, when the term "proximal portion / proximal end" is used, this refers to the portion / end of the delivery device or a component thereof that is located closest to the drug delivery site of the patient.

[0036] The present invention relates to a drug delivery device comprising an elongated housing 150 extending along an axis 200 for containing a drug, a coaxially extending plunger rod 120; 220 mounted within the housing 150 to Axially displaceable for expelling successive doses of medicament, and rotatable about an axis 200, the plunger rod 120; 220 and the housing 150 comprise first guiding means 123; It is adapted to guide the plunger rod 120; 220 inside the housing 150, in order: from a ready-to-use position to a non-ready-to-use position, i...

Abstract

Provided is a medicament delivery device comprising an axially elongated housing, a coaxially extending plunger rod mounted with in the housing for expelling successive doses of medicament and rotatable about the axis. The plunger rod can be axially displaced from a ready-to-use position for expelling a dose of medicament to a non-ready-to-use position axially spaced from said ready-to-use position along the axis, and from said non-ready-to use position to a subsequent ready-to-use position angularly spaced from said non-ready-to use position about the axis The device further comprises an indicator member displaceably mounted onto the housing between a first angular position indicative of the ready-to-use positions and a second angular position indicative of the non-ready-to use positions.

Description

technical field [0001] The present invention relates to a medicament delivery device, and more particularly to a medicament delivery device comprising a support mechanism for conveniently indicating activation or deactivation of the device when a user intends to inject a predetermined amount of medicament. Background technique [0002] Traditionally with conventional hypodermic syringes, the practitioner or user must stop depressing the plunger based on visual feedback, usually from a scale on the hypodermic syringe. As a result, repeated dose injections with high accuracy and / or precision are difficult to perform. [0003] In US 5,318,544 a syringe for metering precise quantities of fluids without the use of visual volume scales is disclosed. This document discloses a syringe container adapted to receive a plunger comprising a plurality of stop surfaces which are angularly and linearly displaced about the plunger longitudinal axis. Translation of the plunger brings the fi...
