1. A connecting structure for connecting a first member in fluid flow connection with a second member, the connecting structure comprising:
- a receptacle structure provided on the first member and having an interior chamber and an opening into the interior chamber;
a first septum provided within the interior chamber, adjacent the opening of the receptacle structure;
a hollow needle supported within the interior chamber of the receptacle structure, the hollow needle having a sharp end with a first opening into which fluid may flow, the sharp end facing the first septum, the hollow needle having a second opening out of which fluid may flow;
a connection portion provided on the second member, the connection portion having a hollow interior chamber and an opening that opens to the hollow interior chamber, the connection portion having a size and shape suitable to be inserted at least partially into the opening of the receptacle structure;
a second septum supported by the connection portion of the second member in a position to cover the opening in the connection portion;
wherein, upon receiving the connection portion within the opening of the receptacle structure, the connection portion pushes the first septum toward the sharp end of the hollow needle, and the sharp end of the hollow needle is caused to pierce the first septum and the second septum to come into fluid flow communication with the hollow interior chamber of the connection portion.

Abstract
A repeater system may control a pump by using a repeater and a user interface. An adhesive patch system may be used for affixing a pump or other object to a human body. Such an adhesive patch system may include two sets of adhesive members, each member including an adhesive material on at least one side so as to attach to the body. The members of the first set are spaced to allow the members of the second set to attach to the body in spaces provided between the members of the first set, and the members of the second set are spaced to allow members of the first set to detach from the body without detaching the members of the second set. Also, fill stations and base stations are provided for personal pump systems.
