Abstract:
A butterfly anchor for an infusion set comprising:a flexible anchor pad having a center line; said flexible anchor pad sized and shaped to cover a backing pad of a butterfly infusion set and to extend beyond a perimeter of said backing pad for a first predetermined distance; said flexible anchor pad having a top surface and a bottom surface, said bottom surface including a means for attachment to the skin of a patient and said backing pad; said flexible anchor pad being flexible enough to contour closely over a joint between a catheter and a tube of a butterfly infusion set; and rigid reinforcing means embedded within said top surface of, parallel to the long axis of, and spaced apart from the center line of said flexible anchor pad with a spacing sufficient to accommodate a center section of a butterfly infusion set backing pad; whereby, when the backing pad of a butterfly infusion set is secured to the skin of a patient by the butterfly anchor, said flexible anchor pad will contour closely over said joint and will prevent a catheter from resting against or puncturing the vein wall during subsequent patient movement.
