Adhesive and peripheral systems and methods for medical devices
First Claim
1. A needle injector device for connection in fluid-flow communication with the inlet or outlet port of a reservoir, the needle injector comprising:
- a housing;
a hollow needle supported in the housing for movement relative to the housing between a start position, an extended position and a retracted position, the needle having a piercing end having an opening and an opposite, second end having an opening;
a fluid conduit connected to the opening on the second end of the hollow needle and moveable with the hollow needle;
a first bias member supported by the housing and arranged to impart a first bias force in a first direction on the attached needle from the start position to the extended position of the needle;
a second bias member arranged to impart a second bias force in a second direction, opposite to the first direction, for moving the attached needle from the extended position to the retracted position;
wherein at least a portion of the first bias member is located outside the housing, and wherein at least a portion of the second bias member is located outside the housing.

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.

18. A method of making a needle injector device for connection in fluid-flow communication with the inlet or outlet port of a reservoir, the method comprising:
-
providing a housing; supporting a hollow needle in the housing for movement relative to the housing between a start position, an extended position and a retracted position, the needle having a piercing end having an opening and an opposite, second end having an opening; connecting a fluid conduit to the opening on the second end of the hollow needle for movement with the hollow needle; arranging a first bias member supported by the housing to impart a first bias force in a first direction on the attached needle from the start position to the extended position of the needle; and arranging a second bias member to impart a second bias force in a second direction, opposite to the first direction, for moving the attached needle from the extended position to the retracted position; wherein at least a portion of the first bias member is located outside the housing, and wherein at least a portion of the second bias member is located outside the housing. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
