Wound or surgical dressing
First Claim
1. A wound or surgical dressing comprising:
- a substrate configured to contact or surround a wound or surgical site, wherein the substrate comprises cellulosic fibers; and
a chemical compound covalently bonded to the cellulosic fibers of the substrate and being located on the substrate so as to contact a patient at or near a wound or surgical site, wherein the covalent bond substantially prevents the chemical compound from transferring to the patient, wherein the chemical compound comprises an aluminum oligomer or an aluminum salt.

Abstract
A wound or surgical dressing is disclosed. The wound or surgical dressing is configured to cover or surround a wound, a surgical incision, or any type of skin irritation. In accordance with the present disclosure, the wound or surgical dressing is treated with a bacteriostatic composition that is capable of binding and trapping negatively charged matter, such as bacteria, pathogens, and the like. The bacteriostatic composition comprises a cationic polymer, a cationic oligomer, or particles coated with a cationic material. The bacteriostatic composition is bonded to the wound or surgical dressing in a manner such that the bacteriostatic composition is not substantially transferred to a patient being treated.

23. A wound or surgical dressing comprising:
-
a substrate comprising cellulosic fibers and configured to contact or surround a wound or surgical site, the substrate comprising a material selected from the group consisting of gauze, a stretch-bonded laminate, a neck-bonded laminate, a spunbond web, a meltblown web, a coform web, an airlaid web, a wetlaid web, and a hydroentangled web; and a chemical compound applied to the substrate, the chemical compound being located on the substrate so as to contact a patient at or near a wound or surgical site, the chemical compound being covalently bonded to the cellulosic fiber of the substrate so that the chemical compound does not substantially transfer to the patient, the chemical compound having a net positive charge for binding with negatively charged matter, the chemical compound comprising an aluminum salt, an aluminum ion, an aluminum complex, an aluminum molecule, or an aluminum oligomer. - View Dependent Claims (24, 25, 29)
