  • Publication number: 20220152307
    Abstract: A medicament delivery device is disclosed having a housing, an actuation mechanism capable of delivering doses of medicament from a medicament container and arranged with a delivery member, a shield, a guard movable within the housing, wherein the guard is operably connected to the actuation mechanism. A protective cap is releasably arranged on the housing and having a shield remover. A blocking element on the guard is movable between a blocking position and a release position and has an engagement surface to engage a proximal area of the housing. The blocking element engages with a surface of the shield remover to retain the blocking element in the blocking position. The engagement surface causes a blocking of the guard from movement and removal of the protective cap enables a movement of the blocking element to a release position when the engagement surface engages the proximal area allowing the member guard to move.

  • Patent number: 11045609
    Abstract: The present invention relates to a needle shield assembly for a syringe (10), comprising an inner needle shield (16) which is flexible and designed to enclose a major part of a hollow injection needle (18) of said syringe; an outer needle shield (20) which is rigid and designed to enclose a major part of said inner needle shield (16), which outer needle shield (20) is arranged with a number of passages (22) for allowing sterilizing agents to reach said injection needle (18) during a sterilization process. The invention is characterised in that said needle shield assembly further comprises a cover element (24; 36; 46) arranged adjacent said passages (22) such as to prevent the interior of said injection needle (18) from being exposed to oxygen via said passages (22) of said outer needle shield (20) after said sterilization process.

  • Patent number: 11033686
    Abstract: An administration mechanism for a medicament delivery device is disclosed having a linearly displaceable medicament delivery member cover, an actuator sleeve, an actuator, wherein the medicament delivery member cover is configured to axially displace the actuator sleeve from an initial position to a distally displaced position thereby displacing the actuator sleeve relative to the actuator, a rotator having a guide structure, a plunger holder, and a plunger rod that is proximally biased. The actuator can engage with the plunger holder in the initial position of the actuator sleeve to prevent the plunger holder from proximal displacement relative to the actuator. The actuator can be released from engagement with the plunger holder by displacement of the actuator sleeve towards the distally displaced position to enable proximal displacement of the plunger holder, the plunger rod and the rotator relative to the actuator.
