Patent ID: 7927317

Claim:
An injection device comprising: a needle support; an injection needle joined to the needle support, the injection needle having a main portion with a free end, the free end being spaced from the needle support; and an extraction mechanism for extracting the injection needle, the extraction mechanism including: a base permanently articulated with the needle support, the base being movable between an inactive position of the extraction mechanism and an active position of the extraction mechanism; a pushing member movable relative to the base between a first position in which the needle is extended and a second position in which the needle is retracted with the free end received in the pushing member; and an engagement member configured to releasably hold the extraction mechanism in the active position, wherein the pushing member lies along an axis of the main portion of the injection needle when the extraction mechanism is in the active position, wherein a hollow portion is defined in the base, the hollow portion constituting a passage for allowing movement of the pushing member, wherein the pushing member is disposed in the passage such that the pushing member is slidably movable between the first position and the second position, and wherein the base is connected to the needle support by a joint such that the base is rotatable relative to the needle support about an articulation axis, the articulation axis being perpendicular to the injection needle.
