US 11,452,848 B2 · Catheter securement device including extended anchor pad and release liner clasping features

Abstract

Embodiments disclosed herein are directed to a securement device including a retainer defining a channel and at least one mounting wing extending therefrom. The mounting wing extends distally of an insertion site a skin surface adjacent to the insertion site to prevent “rocking” or “pistoning.” The mounting wing further includes channels of reduced thickness configured to impart malleable properties on the mounting wing. This can allow the mounting wing to be shaped to fit different portions of the patient. The retainer further includes various locking and anti-rotational features to guide the catheter into position within the retainer and further prevent “rocking” or “pistoning.” The securement device also includes a protective pad to inhibit abrasions from a medical line, spin nuts, and the like, and includes a clasping feature to retain a portion of the release liner to prevent obstructing ingress/egress of the catheter.

Dependent claims

A securement device for stabilizing an elongate medical article on a skin surface of a patient, comprising:

a retainer comprising:
a retainer body defining a channel aligned with a central axis of the securement device, and configured to receive a portion of the elongate medical article;
and
a mounting wing supporting the retainer body;
an anchor pad supporting the mounting wing, including an adhesive layer disposed on a lower surface of the anchor pad, and defining an outer edge and an inner edge disposed laterally opposite the outer edge;
and
a release liner including a first portion disposed on the adhesive layer and extending from the outer edge to the inner edge, and a second portion coupled to the first portion along the inner edge and extending from the inner edge to the outer edge, the release liner including a clasping feature configured to releasably secure the second portion to the first portion proximate the outer edge.
