A drug delivery device for dispensing of a liquid medicament, the drug delivery device comprising:
- a housing to accommodate a cartridge filled with the liquid medicament and having a piston slidably displaced inside the cartridge and sealing the cartridge;
- a resilient member having a first end arranged at an inside facing side wall portion of the housing and having a second end opposite to the first end to abut the piston of the cartridge;
- and
- an electronic suction pump to connect to a distal end of the cartridge for a suction-based extraction of the liquid medicament from the cartridge.
A method of assembling a drug delivery device, the drug delivery device comprising a housing to accommodate a cartridge filled with the liquid medicament and having a piston slidably displaced inside the cartridge and sealing the cartridge, a resilient member having a first end arranged at an inside facing side wall portion of the housing and having a second end opposite to the first end to abut the piston of the cartridge, and an electronic suction pump to connect to a distal end of the cartridge for a suction-based extraction of the liquid medicament from the cartridge, the method comprising:
- inserting the cartridge into an opening of the housing of the drug delivery device;
- and
- placing a sidewall portion of the housing into a closed configuration to cover the opening and cause the second end of the resilient member of the drug delivery device to abut the piston of the cartridge.
