Abstract
The present invention provides a method for using a stabilized foam that is a crosslinked, closed cell polyolefin having a stabilizing layer and an adhesive layer. The method can be used for treating a wound, scrape, abrasion or skin puncture, for maintaining cleanliness of an operation incision site, suture site, catheter insertion site, or an intentional skin breach site, for monitoring electrical impulses during an EKG or for delivering electrical impulses in TENS or biofeedback therapy, and for reducing scar formation by softening collagen deposits.
Claims25
A method of treating a wound, scrape, abrasion, or skin puncture comprising:
- applying a stabilized foam to said wound, scrape, abrasion, or skin puncture, wherein said stabilized foam comprises:
- a cross-linked, closed cell polyolefin foam layer having a top surface and a bottom surface;
- a stabilizing layer disposed on said top surface of said cross-linked closed cell polyolefin foam layer, wherein said stabilizing layer improves one or more of the tensile, tear, and stretch/recovery properties of said polyolefin foam layer, thereby providing strength and stability to said polyolefin foam layer, wherein said stabilizing layer is not an adhesive layer;
- and
- an adhesive layer disposed on either said stabilizing layer or said bottom surface of said polyolefin foam layer, said adhesive layer being substantially flat;
- and
- applying said adhesive layer directly to a skin surface of a human body.

A method of treating a wound, scrape, abrasion, or skin puncture comprising:
- applying a stabilized foam to said wound, scrape, abrasion, or skin puncture, wherein said stabilized foam comprises:
- a cross-linked, closed cell polyolefin foam layer having a top surface and a bottom surface;
- a stabilizing layer disposed on said bottom surface of said cross-linked closed cell polyolefin foam layer, said stabilizing layer having a top surface and a bottom surface, wherein said stabilizing layer improves one or more of the tensile, tear, and stretch/recovery properties of said polyolefin foam layer, thereby providing strength and stability to said polyolefin foam layer, and wherein said stabilizing layer is not an adhesive layer;
- and
- an adhesive layer disposed on said bottom surface of said stabilizing layer, said adhesive layer being substantially flat;
- and
- applying said adhesive layer directly to a skin surface of a human body.

A method of monitoring electrical impulses in a patient during EKG or delivering electrical impulses to a patient in a TENS or biofeedback therapy comprising:
- treating said patient with a foam electrical grounding pad or a foam device having a stabilized foam, wherein said stabilized foam comprises:
- a cross-linked, closed cell polyolefin foam layer having a top surface and a bottom surface;
- a stabilizing layer disposed on said top surface of said cross-linked closed cell polyolefin foam layer, wherein said stabilizing layer improves one or more of the tensile, tear, and stretch/recovery properties of said polyolefin foam layer, thereby providing strength and stability to said polyolefin foam layer, wherein said stabilizing layer is not an adhesive layer;
- and
- an adhesive layer disposed on said top surface of said polyolefin foam layer, said adhesive layer being substantially flat;
- and applying said adhesive layer of said stabilizing foam of said foam electrical grounding pad or foam device to a skin surface of a human body.
3 more elements
A method of softening scar tissue and collagen deposits in a scar, and reducing visibility of a raised or keloid portion of the scar over time, comprising:
- treating the scar with a stabilized foam, wherein said stabilized foam comprises:
- a cross-linked, closed cell polyolefin foam layer having a top surface and a bottom surface;
- a stabilizing layer disposed on said top surface of said cross-linked closed cell polyolefin foam layer, wherein said stabilizing layer improves one or more of the tensile, tear, and stretch/recovery properties of said polyolefin foam layer, thereby providing strength and stability to said polyolefin foam layer, wherein said stabilizing layer is not an adhesive layer;
- and
- an adhesive layer disposed on said top surface of said polyolefin foam layer, said
- adhesive layer being substantially flat;
- and applying said adhesive layer of said
- stabilized foam to a skin surface of a human body.
5 more elements
A method of maintaining cleanliness of an operation incision site, suture site, catheter insertion site, or an intentional skin breach site comprising:
- applying a stabilized foam to said operation incision site, suture site, catheter insertion site, or an intentional skin breach site, and a shower water block system, wherein said stabilized foam comprises:
- a cross-linked, closed cell polyolefin foam layer having a top surface and a bottom surface;
- a stabilizing layer disposed on said top surface of said cross-linked closed cell polyolefin foam layer, wherein said stabilizing layer improves one or more of the tensile, tear, and stretch/recovery properties of said polyolefin foam layer, thereby providing strength and stability to said polyolefin foam layer, wherein said stabilizing layer is not an adhesive layer;
- and
- an adhesive layer disposed on said top surface of said polyolefin foam layer, said adhesive layer being substantially flat;
- and applying said adhesive layer of said stabilizing foam of said water block system to a skin surface of a human body.
3 more elements
A method of treating a wound, scrape, abrasion, or skin puncture comprising:
- applying a stabilized foam to said wound, scrape, abrasion, or skin puncture, wherein said stabilized foam comprises:
- a cross-linked, closed cell polyolefin foam layer having a top surface and a bottom surface, said cross-linked closed cell polyolefin foam layer having a thickness of about 0.010 inches to about 0.031 inches;
- a first stabilizing layer disposed on said top surface of said cross-linked closed cell polyolefin foam layer, said first stabilizing layer having a top surface and a bottom surface, wherein said first stabilizing layer is not an adhesive layer;
