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.

What is claimed is: 
     
         1 . A securement device for stabilizing a catheter assembly, comprising:
 a retainer configured to receive a portion of the catheter assembly;   an anchor pad comprising a top layer coupled to the retainer and a bottom layer comprising an adhesive; and   a release liner, comprising:
 a first portion adhered to the bottom layer of the anchor pad; and 
 a second portion coupled to the first portion along an inner edge of the first portion, wherein the second portion:
 is folded under the first portion, 
 extends laterally beyond an outer edge of the first portion, and 
 includes a clasping feature configured to releasably secure the second portion to the anchor pad. 
 
   
     
     
         2 . The securement device according to  claim 1 , wherein the clasping feature comprises a flap created by a partial cut into the second portion extending laterally beyond an outer edge of the first portion of the release liner. 
     
     
         3 . The securement device according to  claim 2 , wherein an outer edge of the anchor pad has an indented portion, and wherein the flap is positioned in the second portion to releasably couple the second portion to the indented portion of the anchor pad. 
     
     
         4 . The securement device according to  claim 1 , wherein the clasping feature comprises an aperture in the first portion of the release liner, the aperture permitting the second portion of the release liner to contact the adhesive layer through the aperture. 
     
     
         5 . The securement device according to  claim 1 , wherein the top layer of the anchor pad comprises a fabric layer and a foam layer under the fabric layer, and wherein the adhesive is disposed on at least a portion of the foam layer. 
     
     
         6 . The securement device according to  claim 1 , further comprising a protective pad nested in a central portion of the anchor pad along a proximal edge of the anchor pad, the protective pad including an aperture configured to receive the catheter assembly therethrough. 
     
     
         7 . The securement device according to  claim 6 , wherein the protective pad comprises a tear line disposed from the aperture to the central portion of the anchor pad, the tear line configured to selectively release the protective pad from the securement device. 
     
     
         8 . The securement device according to  claim 7 , wherein the protective pad has a thickness equivalent to a thickness of the anchor pad. 
     
     
         9 . The securement device according to  claim 1 , wherein the catheter assembly includes a catheter selected from the group consisting of a midline catheter, a dialysis catheter, a central venous catheter (“CVC”), a peripherally inserted central catheter (“PICC”), and a peripherally inserted venous catheter (“PIV”). 
     
     
         10 . The securement device according to  claim 1 , wherein the anchor pad comprises a first anchor pad and a second anchor pad separated from the first anchor pad by a gap, and wherein the retainer comprises:
 a retainer body defining a channel aligned with the gap between the first anchor pad and the second anchor pad;   a first mounting wing extending from a first side of the retainer body, the first mounting wing coupled to the first anchor pad; and   a second mounting wing extending from a second side of the retainer body, the second mounting wing coupled to the second anchor pad.   
     
     
         11 . The securement device according to  claim 10 , wherein the release liner comprises a first release liner coupled to the first anchor pad, and a second release liner coupled to the second anchor pad. 
     
     
         12 . The securement device according to  claim 10 , wherein each of the first mounting wing and the second mounting wing includes a channel configured to impart malleable characteristics. 
     
     
         13 . The securement device according to  claim 12 , wherein a thickness of the channel is in a range between 0.010 in. and 0.020 in. 
     
     
         14 . The securement device according to  claim 10 , wherein the retainer is configured to mitigate rocking or pistoning of the catheter assembly. 
     
     
         15 . The securement device according to  claim 10 , wherein the retainer body includes a window to permit viewing of the catheter assembly when disposed in the channel to verify proper alignment of the catheter assembly in the channel. 
     
     
         16 . The securement device according to  claim 1 , wherein the retainer body is formed of a transparent, translucent, or semi-translucent material.
