1. A method for operating a wearable medical device, wherein said wearable medical device has a unitary disposable assembly and a unitary reusable assembly releasably engageable to the disposable assembly; the disposable assembly having a reservoir with a fluid and the reservoir fluidly connected to a pump section with a fluid channel defining a volume and having an inlet portion, an exit portion and a flexible membrane between the inlet and exit portions; the reusable assembly having a control assembly with an actuation member, the method comprising:
engaging the disposable assembly to the reusable assembly;
flexing the flexible membrane by contact with the actuation member of the control assembly to change the volume of the fluid channel to thereby move fluid from the inlet portion to the exit portion to pump the fluid from the reservoir; and
maintaining the fluid in the disposable assembly so that the fluid is not in contact with the reusable assembly.
