Straight insertion safety infusion set
First Claim
1. An infusion set assembly comprising:
- a cannula housing having a base surface adapted to be removeably attached to a user'"'"'s skin;
an insertion needle assembly including an insertion needle;
a cannula supported by the needle assembly with a tip of the insertion needle extending from a distal end of the cannula;
an insertion guide housing configured to support the insertion needle assembly relative to the cannula housing with the needle substantially perpendicular to the base surface and adapted for movement between a first needle assembly position where the needle tip and cannula distal end are spaced from the base surface and a second needle assembly position where the needle tip and cannula distal end extend beyond the base surface; and
. a septum housing configured to receive and support the cannula relative to the cannula housing.

Abstract
An infusion set assembly comprising a cannula housing having a base surface and a septum housing adapted to be pivotally attached to the cannula housing for movement between a position where an axis thereof is substantially perpendicular to the base surface and a position where the axis is substantially parallel to the base surface. The infusion set assembly further comprises an insertion needle assembly including an insertion needle and a cannula supported by the needle assembly with a tip of the insertion needle extending from a distal end of the cannula. An insertion guide housing is configured to support the insertion needle assembly with the needle substantially perpendicular to the base surface and adapted for movement between a position where the needle tip and cannula distal end are spaced from the base surface and a position where the needle tip and cannula distal end extend beyond the base surface.

27. A method of inserting a cannula through skin of a user, comprising:
-
providing an infusion set assembly comprising;
a cannula housing having a base surface;
an insertion needle assembly including an insertion needle;
a cannula supported by the needle assembly with a tip of the insertion needle extending from a distal end of the cannula; and
an insertion guide housing configured to support the insertion needle assembly relative to the cannula housing and adapted for movement between a first needle assembly position where the needle tip and cannula distal end are spaced from the base surface and a second needle assembly position where the needle tip and cannula distal end extend beyond the base surface;
positioning the needle assembly in the first needle assembly position;
removably adhering the cannula housing to the skin of the user;
advancing the needle assembly from the first needle assembly position to the second needle assembly position;
removing the insertion guide assembly and the insertion needle assembly from the cannula housing and the septum housing. - View Dependent Claims (28, 29, 30, 31)

32. An infusion set assembly comprising:
-
a cannula housing having a base surface;
an insertion needle assembly including an insertion needle;
a cannula supported by the needle assembly with a tip of the insertion needle extending from a distal end of the cannula;
an insertion guide housing configured to support the insertion needle assembly with the needle substantially perpendicular to the base surface and adapted for movement between a first needle assembly position wherein the needle tip and cannula distal end are spaced from the base surface and a second needle assembly position wherein the needle tip and cannula distal end extend beyond the base surface; and
a septum housing having an axial bore configured to receive and support a proximal portion of the cannula, the septum housing being pivotally attached to the cannula housing for movement between a first septum housing position where an axis of the bore is substantially perpendicular to the base surface and a second septum housing position where the axis is substantially parallel to the base surface. - View Dependent Claims (33, 34)
