Abstract

A barrier system is provided for use in reducing infections associated with a percutaneous medical device, such as a catheter, that is disposed within a percutaneous incision. Such a barrier system can include: a barrier device having a skin-contacting surface and a catheter-receiving surface; and an adhesive composition configured for adhering to skin, the barrier device, and/or the catheter so as to form a barrier at or adjacent to an incision in the skin where the catheter is percutaneously inserted through the skin. The barrier device can include a conduit configured to receive the catheter. Alternatively, the barrier device can include a groove in a base surface that is configured to receive the catheter. A system that includes a medical device, the barrier device, and adhesive can also be provided.

First claim

The invention claimed is:

1. A barrier system for reducing infections associated with an opening in a patient's skin, said barrier system comprising:
a barrier device having a skin-contacting surface;
an expandable bladder for releasing the barrier device from skin associated with the skin-contacting surface, the expandable bladder is disposed on the barrier device; and
a cyanoacrylate adhesive composition configured for adhering to skin, the barrier device, and/or the one or more of an expandable bladder so as to form an anti-microbial barrier at or adjacent to the opening in the patient's skin, and wherein the expandable bladder is capable of breaking a cyanoacrylate adhesive-skin bond.

2. The barrier system as in claim 1 , wherein the cyanoacrylate is ethyl-2-cyanoacrylate, and 2-octyl cyanoacrylate, or n-butyl-cyanoacrylate.

3. The barrier system as in claim 1 , further comprising at least one of the following:
one or more fastener straps on the barrier device that is configured to be affixed to the skin outward from the barrier device;
a tapered base opening or opposite opening;
a recess in a base surface configured for receiving the adhesive;
a clam slit;
a groove adjacent with the opposite opening;
an o-ring; or
a chilling fluid conduit in the barrier device that communicates with a location for receiving the adhesive.

4. A method for reducing infections associated with an opening in a patient's skin, said method comprising:
applying a cyanoacrylate adhesive composition to the skin and/or an adhesive receiving surface of a barrier device having a skin-contacting surface with the adhesive receiving surface, and one or more of an expandable bladder or release cord; and
adhering the barrier device to the skin with the cyanoacrylate adhesive composition so as to form an anti-microbial barrier with respect to the opening and the one or more of an expandable bladder or release cord to inhibit microbes from infecting the opening.

5. A method as in claim 4 , wherein the adhesive is applied to at least one of the following:
a junction between the barrier device and skin; or
a junction between the barrier device, skin, and air.

6. A barrier system for reducing infections associated with an opening in a patient's skin, said barrier system comprising:
a barrier device having a skin-contacting surface;
a release cord for releasing the barrier device from skin associated with the skin-contacting surface, the release cord disposed on the skin-contacting surface of the barrier device; and
a cyanoacrylate adhesive composition configured for adhering to skin, the barrier device, and/or the release cord so as to form an anti-microbial barrier at or adjacent to the incision in the patient's skin, and wherein the release cord is capable of breaking a cyanoacrylate adhesive-skin bond.

7. The barrier system as in claim 6 , wherein the cyanoacrylate is ethyl-2-cyanoacrylate, and 2-octyl cyanoacrylate, or n-butyl-cyanoacrylate.

8. The barrier system as in claim 6 , further comprising at least one of the following:
one or more fastener straps on the barrier device that is configured to be affixed to the skin outward from the barrier device;
a tapered base opening or opposite opening;
a recess in a base surface configured for receiving the adhesive;
a clam slit;
a groove adjacent with the opposite opening;
an o-ring; or
a chilling fluid conduit in the barrier device that communicates with a location for receiving the adhesive.
