Needle insertion systems and methods
First Claim
1. A medical device comprising:
- a medical monitoring or treatment device configured to provide a monitoring or treatment operation on a user, the medical monitoring or treatment device operable with an insertion needle or cannula that is moveable from a retracted position to an extended position;
a housing adapted to be secured to the user adjacent an injection site on the user'"'"'s skin and to hold the medical monitoring or treatment device during operation of the medical monitoring or treatment device, the housing having a passage with a longitudinal length dimension through and along which the insertion needle or cannula moves to pierce the user'"'"'s skin when the housing is secured to the user and the insertion needle or cannula is moved from the retracted position to the extended position;
a magnifying material arranged on the housing at a location that allows viewing of the injection site through the housing passage, by looking through the magnifying material and down the longitudinal length dimension of the housing passage when piercing the skin of the user with the insertion needle or cannula.

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.

27. A medical device comprising:
-
a medical monitoring or treatment device configured to provide a monitoring or treatment operation on a user, the medical monitoring or treatment device operable with an insertion needle or cannula that is moveable from a retracted position to an extended position; a housing adapted to be secured to the user adjacent an injection site on the user'"'"'s skin and to hold the medical monitoring or treatment device during operation of the medical monitoring or treatment device, the housing having a passage with a longitudinal length dimension through and along which the insertion needle or cannula moves to pierce the user'"'"'s skin when the housing is secured to the user and the insertion needle or cannula is moved from the retracted position to the extended position; a needle inserting device configured to selectively move the insertion needle or cannula along the longitudinal length dimension of the housing passage from the retracted position to the extended position when the housing is secured to the patient, to insert the insertion needle into the user; a magnifying material arranged on one of the housing and the needle inserting device, at a location that allows viewing of the injection site through the housing passage, by looking through the magnifying material and down the longitudinal length dimension of the housing passage when piercing the skin of the user with the insertion needle or cannula. - View Dependent Claims (28, 29, 30)
