US 2008/0177234 A1 · Safety subcutaneous infusion set

Abstract

A safety butterfly infusion set comprising a catheter, a length of flexible tubing in fluid communication with the catheter, and a butterfly anchor formed with a central body having a notch formed therein and leading sideward into the body for centering and seating a delivery tube in a press-fit manner. The butterfly anchor also has hinges on opposing sides of the body that support a pair of opposing foldable wings. A locking post protrudes from the distal end of one wing and when the wings are folded together the locking post may be inserted into a hole at the distal tip of the other wing for releasably locking the wings together. Thus, the wings can be conveniently folded over the catheter and latched in place to protect the user from pricking after use. On the other hand, when the wings are unfolded for use they lay perfectly flat against a patient's skin, thereby allowing adhesion of a strip of dermal tape such as Tegaderm™ overtop to anchor the catheter in place and promote needle stability.

Dependent claims

An infusion set comprising:

an angled catheter;
a length of flexible tubing in fluid communication with said catheter;
an anchoring member, said anchoring member further comprising a central body formed with a flat bottom surface, a top and sides, and a notched recess entering from the side and open at the top of said body for centering and seating the delivery tube in a press-fit manner, said notched recess leading to a through hole through the bottom surface for insertion of said angled catheter therein, said anchoring member further comprising a pair of opposing foldable wings joined to the sides of said central body at hinges, and a detent post mounted distally in one of said wings for locking engagement in an aperture positioned distally in the other said wing;
wherein when a length of said catheter protruding from said through hole is transdermally inserted into a patient the opposing wings lie flat against said patient's skin in an unfolded position to facilitate tape-adhesion of the infusion set to said skin, and when said infusion set is removed the wings may be folded together over said protruding catheter and locked together by insertion of said detent post into said aperture.
