INFUSION MEDIUM DELIVERY DEVICE AND METHOD WITH DRIVE DEVICE FOR DRIVING PLUNGER IN RESERVOIR
First Claim
1. A delivery device for delivering an infusion medium to a user, the device comprising:
- a first housing portion adapted to be carried by a user;
a second housing portion configured to be selectively operatively engaged with and disengaged from the first housing portion;
a reservoir supported by one of the first and second housing portions;
at least one of a drive device and a needle inserting device supported by the other of the first and second housing portions relative to the housing portion that supports the reservoir, such that upon the first and second housing portions being operatively engaged, the reservoir is operatively coupled to the at least one of a drive device and a needle inserting device; and
a first pair of magnets including a first magnet supported on the first housing portion and a second magnet supported on the second housing portion in a position to magnetically interact with the first magnet, upon the first and second housing portions being operatively engaged.

Abstract
A delivery device includes first and second housing portions that selectively engage and disengage. A reservoir on one housing portion operatively engages a drive device and/or a needle inserting device on the other housing portion. Upon proper engagement of the housing portions, the reservoir operatively couples to the drive device and/or the needle inserting device. A first magnet on the first housing portion and a second magnet (or a magnetically-attractive material) on the second housing portion are positioned to magnetically interact with each other, upon operative engagement of the housing portions. A third magnet on the second housing portion may be opposed to the first magnet to help align the housing portions for connection. A magnet-responsive device may be on one or both housing portions to detect alignment and/or connection of the housing portions.

22. A delivery device for delivering an infusion medium to a user, the device comprising:
-
first and second housing portions adapted to be carried by a user and configured to be selectively engaged together for operation and selectively separated from each other;
a reservoir supported by the first housing portion, the reservoir including a reservoir housing having an interior volume, a plunger head moveable within the reservoir interior to selectively change the volume of the reservoir interior and a plunger shaft extending from the plunger head to a position outside of the reservoir housing;
a nut member having an open side, the nut member being supported in a fixed relation with the plunger shaft of the reservoir, the nut member having a structure for engaging a threaded shaft in any one of a plurality of positions in a first dimension relative to the nut member;
a rotatable lead shaft supported by the second housing portion for rotation about a rotary axis, the rotatable lead shaft being supported by the second housing portion in a position to be inserted through the open side of the nut member to threadably engage with the nut member, as the first and second housing portions are brought together for operative engagement. - View Dependent Claims (23, 24, 25, 26, 27, 28)
