NEEDLE INSERTION SYSTEMS AND METHODS
First Claim
1. A needle-inserting device comprising:
- a housing having an internal chamber and a longitudinal dimension;
a plunger arranged for movement within the internal chamber, in the direction of the longitudinal dimension of the housing, from a first plunger position to a second plunger position;
a bias mechanism for imparting a bias force on the plunger when the plunger is in the first plunger position, wherein the bias force is directed toward the second plunger position; and
a needle connected to the plunger for movement with the plunger; and
the plunger having a tab end configured to retain the plunger in the first plunger position, the tab end moveable relative to the housing;
wherein upon movement of the tab end, the plunger is free to move from the first plunger position to the second plunger position under the bias force imparted by the bias mechanism to move the needle to an insert position.

Abstract
A housing may have a needle, plunger, and bias mechanism supported within the housing by a tab configured to retain the plunger in position and to allow the plunger to move under bias force imparted by the bias mechanism to move the needle to an insert position when the tab is removed. A base and a structure may be configured for relative movement there between and may be adapted to be secured to a user with a cannula extending through a body of the structure into the user during use of a medical device. A housing may be adapted to be secured to a user to support a medical device operable with an insertion needle, the housing having a magnifying material for increasing visibility of an injection site.

17. A method of making a needle-inserting device, the method comprising:
-
providing a housing having an internal chamber and a longitudinal dimension; arranging a plunger for movement within the internal chamber, in the direction of the longitudinal dimension of the housing, from a first plunger position to a second plunger position; providing a bias mechanism for imparting a bias force on the plunger when the plunger is in the first plunger position, wherein the bias force is directed toward the second plunger position; and locating a needle connected to the plunger, for movement with the plunger; and configuring a tab end of the plunger to retain the plunger in the first plunger position, the tab end moveable relative to the housing such that upon movement of the tab end from the plunger the plunger is free to move from the first plunger position to the second plunger position under the bias force imparted by the bias mechanism to move the needle to an insert position.
