Adhesive and Peripheral Systems and Methods for Medical Devices

摘要

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.

主权项

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 provided with an interior channel having a longitudinal, axial dimension and a slot-shaped opening extending through a wall of the housing to the channel and extending along at least a portion of the longitudinal length of the channel; a hollow needle supported in the channel 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, the fluid conduit being connectable to the outlet or inlet port of the reservoir; a lever member connected in a fixed relation to the hollow needle and having a extension portion extending through the slot-shaped opening in the housing; a first bias member supported by the housing and arranged to impart first bias force on the lever in a first direction, for moving the lever and 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 on the lever in a second direction, opposite to the first direction, for moving the lever and the attached needle from the extended position to the retracted position.
