Multi-position infusion set device and process
First Claim
1. An infusion set comprising:
- a base removably attachable to an infusion site for providing a subcutaneous path for an infusant, the base having a cannula;
a hub removably attachable to the base, the hub including a needle for extending through the base and through the cannula; and
a guard removably attachable to the hub for surrounding the needle when the guard is attached to the hub;
wherein, upon removal of the guard, the needle is subcutaneously insertable into the infusion site for subcutaneously positioning the cannula;
wherein the guard engages the hub when the guard is attached to the hub and is surrounding the needle.

Abstract
An infusion set for subcutaneous delivery of an infusant. The infusion set may include a base removably attachable to an infusion site and a connector temporarily lockable to the base. The connector can engage the base in a plurality of orientations. The connector locks into the base after at least partial rotation of the connector about the base. The connector may include flexible arms which unlock the connector from the base. The base includes a cannula for insertion through the infusion site. The connector includes a tubing for passing the infusant. The infusant is subcutaneously passable from the tubing through the cannula when the connector is attached to the base. The infusion set may also include a hub removably attachable to the base that includes a needle that extends through the base and the cannula and a guard removably attachable to the base opposite the hub for surrounding the needle.

11. An infusion set comprising:
-
a base removably attachable to an infusion site for providing a subcutaneous path for an infusant, the base having a cannula; a hub removably attachable to the base, the hub including a needle for extending through the base and through the cannula; and a guard removably attachable to the base opposite the hub for surrounding the needle, the guard and the base having at least one aperture and locking surface and at least one tab for engaging the at least one aperture, for releasably attaching the guard to the base; wherein the guard is at least partially rotatable about an axis of the base; wherein rotation of the guard about the base causes the tab to engage with the locking surface to inhibit separation of the guard from the base in an axial direction parallel to the axis of the base; and wherein, upon removal of the guard, the needle is subcutaneously insertable into the infusion site for subcutaneously positioning the cannula. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. An infusion set comprising:
-
a base removably attachable to an infusion site for providing a subcutaneous path for an infusant, the base having a cannula; a hub removably attachable to the base, the hub including a needle for extending through the base and through the cannula; and a guard removably attachable to the base opposite the hub for surrounding the needle, the guard and the base having at least one aperture and at least one tab for engaging the at least one aperture, for releasably attaching the guard to the base, the guard having a flexible body capable of being manually squeezed to release and remove the guard from the base when the guard is attached to the base; wherein, upon removal of the guard, the needle is subcutaneously insertable into the infusion site for subcutaneously positioning the cannula; the base having a plurality of apertures and the guard having a plurality of tabs for engaging the plurality of apertures of the base for releasably connecting the guard to the base; the base having a plurality of locking surfaces; wherein the guard is at least partially rotatable about an axis of the base; and wherein rotation of the guard about the base causes the plurality of tabs to engage with the plurality of locking surfaces to inhibit separation of the guard from the base in an axial direction parallel to the axis of the base.
