Intravenous securement device with adhesively interconnected anchoring component and permeable adhesive strip

Abstract

A catheter anchoring assembly includes a permeable adhesive strip, a platform for securing the catheter, and a flowable adhesive layer. The flowable adhesive layer adhesively secures the platform to the adhesive strip. The flowable adhesive is applied to one side of the strip with a skin-contacting adhesive on the opposite side of the strip. The flowable adhesive layer and strip are configured so that the flowable adhesive is spaced from the skin-contacting adhesive or, at the very least, is prevented from penetrating the skin-contacting adhesive. The flowable adhesive layer and strip also permit the assembly to be very flexible and, thus, comfortable for a patient to wear.

1 . An intravenous catheter anchoring device for securing a catheter to a patient, the device comprising:
 a base including an upper surface and a lower surface;   a plurality of posts extending from the upper surface;   a cover cooperating with the base and the plurality of posts to define a catheter-receiving passageway configured to receive a portion of the catheter; and   a flexible strip having a top surface attached to the lower surface of the base by an adhesive and having a bottom surface, at least a portion of the bottom surface being covered by a skin-contacting adhesive layer, the flexible strip having a thickness of about 0.005 to 0.015 inches and being liquid permeable from the top surface to the bottom surface;   a release liner removably attached to at least a portion of the skin-contacting adhesive layer, the release liner not contacting the adhesive.   
     
     
         2 . The device as claimed in  claim 1 , wherein the adhesive comprises hot-melt adhesive. 
     
     
         3 . The device as claimed in  claim 2 , wherein the hot-melt adhesive comprises thermoplastic polyamide. 
     
     
         4 . The device as claimed in  claim 1 , wherein the adhesive is spaced from the release liner when solidified. 
     
     
         5 . The device as claimed in  claim 1 , wherein the flexible strip has a thickness from the top surface to the bottom surface of about 0.008 inches. 
     
     
         6 . The device as claimed in  claim 1 , wherein the flexible strip includes a polyester substrate. 
     
     
         7 . The device as claimed in  claim 1 , wherein the adhesive remains flexible after being solidified. 
     
     
         8 . The device as claimed in  claim 1 , wherein the flexible strip comprises a non-woven tricot fabric substrate. 
     
     
         9 . The device as claimed in  claim 8 , wherein the substrate includes filaments forming interstices therebetween, the adhesive mechanically interlocking with at least some of the filaments. 
     
     
         10 . An intravenous catheter anchoring device for securing a catheter to a patient, the device comprising:
 a base including an upper surface and a lower surface;   a plurality of posts extending from the upper surface to define a catheter-receiving passageway configured to receive a portion of the catheter; and   a flexible strip having first and second opposite surfaces and a thickness therebetween of about 0.005 to 0.015 inches, the flexible strip being liquid permeable from the first surface to the second surface;   a skin-contacting adhesive layer disposed on at least a portion of the flexible strip for contacting a patient; and   an adhesive adhering the base to the flexible strip and permeating the flexible strip without mixing with the skin-contacting adhesive layer.   
     
     
         11 . The device as claimed in  claim 10  further comprising a cover cooperating with the base. 
     
     
         12 . The device as claimed in  claim 10  further comprising a release liner removably attached to the skin-contacting adhesive layer. 
     
     
         13 . The device as claimed in  claim 10 , wherein the adhesive comprises a hot-melt adhesive. 
     
     
         14 . The device as claimed in  claim 13 , wherein the hot-melt adhesive comprises thermoplastic polyamide. 
     
     
         15 . The device as claimed in  claim 10 , wherein the flexible strip includes a polyester substrate. 
     
     
         16 . The device as claimed in  claim 10 , wherein the flexible strip comprises a non-woven tricot fabric substrate. 
     
     
         17 . The device as claimed in  claim 10 , wherein the flexible strip includes a substrate having filaments forming interstices therebetween, the adhesive mechanically interlocking with at least some of the filaments. 
     
     
         18 . The device as claimed in  claim 10 , wherein the adhesive extends a depth greater than about half the thickness of the flexible strip. 
     
     
         19 . An intravenous catheter anchoring device for securing a catheter to a patient, the device comprising:
 a base including an upper surface;   a plurality of posts extending from the upper surface;   a flexible strip having first and second opposite surfaces with a thickness therebetween of about 0.005 to 0.015 inches, the strip being liquid permeable from the first surface to the second surface;   a skin-contacting adhesive layer adhered to at least a portion of the first surface; and   an adhesive layer bonding the base to the flexible strip, the adhesive layer being restricted from adhering the flexible strip to the patient.   
     
     
         20 . The device as claimed in  claim 19  further comprising a release liner removably attached to the skin-contacting adhesive layer so that the first surface is at least partly covered by the release liner before the strip is attached to the patient.
