1. A medicament delivery device comprising:
a main body;
a cartridge arranged in the main body, wherein the cartridge comprises a medicament;
a delivery member shield unit slidably arranged in the main body;
a removable cap directly abutting the delivery member shield unit;
a plunger rod operatively arranged to eject the medicament through a delivery member attached to the cartridge; and
a tubular member arranged inside the delivery member shield unit, where the tubular member comprises a track and is coupled to the plunger rod,
wherein the delivery member shield unit comprises a pin configured to interact with the track of the tubular member, and
wherein, during removal of the removable cap, the pin on the delivery member shield unit travels in the track on the tubular member so as to cause rotation of the tubular member that releases the plunger rod thereby allowing the plunger rod to travel a predetermined distance so as to automatically prime the medicament delivery device.
