Medicament delivery device

A medicament delivery device comprising:

• a housing having a proximal end and a distal end;
• a multi-chamber container arranged in the housing;
• a container holder axially and rotationally fixed to the housing and in which the multi-chamber container is accommodated;
• a needle shield sleeve slidably arranged in the housing;
• a power assembly having accumulated energy, arranged in the housing and configured to act on the multi-chamber container for obtaining and delivering a blended compound inside the multi-chamber container, wherein a portion of the power assembly is axially fixed in the housing;
• and
• a manually operable assembly extending from the distal end of the housing and being connected with the power assembly,
• wherein the manually operable assembly is connected with the portion of the power assembly that is axially fixed in the housing by a threaded connection,
• wherein a rotational movement of the manually operable assembly by a user of the medicament delivery device causes linear movement of the power assembly towards the proximal end to pressurize the multi-chamber container, and
• wherein the needle shield sleeve is configured to interact with the power assembly to release the accumulated energy after the power assembly has moved towards the proximal end.
