1. A base assembly for a fluid delivery system comprising a fluid reservoir with a fluid vent for expelling pressurized fluidic media from the fluid reservoir, the base assembly comprising:

  • a proximal portion;

    a distal portion formed with a fluid delivery port to accommodate transfer of fluidic media;

    a valve to cooperate with the fluid delivery port;

    a recess to accommodate the fluid reservoir in a first state of the base assembly, and to accommodate the valve in a second state of the base assembly; and

    a sealing arrangement that cooperates with the valve and the fluid reservoir;

    wherein, in the first state, the sealing arrangement cooperates with the fluid reservoir to form a fluid tight chamber in fluid communication with the fluid vent of the fluid reservoir; and

    wherein, in the second state, the sealing arrangement cooperates with the valve to inhibit access to the fluid delivery port.
