Infusion medium delivery device and method with drive device for driving plunger in reservoir
First Claim
1. A medical device for delivering an infusion medium to a user, the medical 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 connected to one of the first and second housing portions;
at least one of a drive device or a needle inserting device supported by the other of the first and second housing portions relative to the respective housing portion to which the reservoir is connected, such that upon the first and second housing portions being operatively engaged, the reservoir is operatively coupled to at least one of the drive device or the needle inserting device;
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 improperly aligned when brought toward each other for operative engagement;
wherein the first and second magnets are positioned relative to each other so as to impart a repelling force directed toward properly aligning the first and second housing portions for operative engagement.

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.

19. A medical device for delivering an infusion medium to a user, the medical 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 connected to one of the first and second housing portions; at least one of a drive device or a needle inserting device supported by the other of the first and second housing portions relative to the respective housing portion to which the reservoir is connected, such that upon the first and second housing portions being operatively engaged, the reservoir is operatively coupled to at least one of the drive device or the needle inserting device; 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 improperly aligned when brought toward each other for operative engagement; wherein each of the first magnet and the second magnet has a pole that faces a pole of the other of the first magnet and the second magnet when the first and second housing portions are improperly aligned when brought toward each other for operative engagement; and wherein the facing poles of the first magnet and the second magnet are of the same polarity such that the first magnet and second magnet mutually repel each other upon the first and second housing portions being improperly aligned when brought toward each other for operative engagement.

20. A medical device for delivering an infusion medium to a user, the medical 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 or a needle inserting device supported by the other of the first and second housing portions relative to the respective housing portion that supports the reservoir, such that upon the first and second housing portions being operatively engaged, the reservoir is operatively coupled to at least one of the drive device and the needle inserting device; a first magnet supported on the first housing portion; and a second magnet supported on the second housing portion in a position to repel the first magnet upon the first and second housing portions being improperly aligned when brought toward each other for operative engagement.
