The drive mechanism may include a housing having a pump chamber fluidly connected with a channel chamber, an inlet channel operable to deliver the liquid drug from the reservoir to the channel chamber, and an outlet channel operable to expel the liquid drug from the channel chamber. The drive mechanism may further include a resilient sealing member sealing the pump chamber, and a plunger adjacent the resilient sealing member, wherein the plunger is operable to enter the pump chamber to displace the liquid drug from the pump chamber.
