## Abstract

A splinting system that includes a curable splint member including layers of fiberglass cloth coated with a water curable resin, and a pad at least partially enveloping the layers of fiberglass cloth, the pad having an exterior surface and an antimicrobial coating applied to the exterior surface; and a metal foil pouch containing the curable splint member, the metal foil pouch including an exterior surface. The antimicrobial coating includes a silane quaternary ammonium ion or salt thereof. The silane quaternary ammonium ion or salt thereof is one or more of: 3-(trimethoxysilyl)propyldimethyloctadecyl ammonium ion, 3-(trimethoxysilyl)propyldimethyloctadecyl ammonium chloride, 3-(trihydroxysilyl)propyldimethyloctadecyl ammonium ion, or 3-(trihydroxysilyl)propyldimethyloctadecyl ammonium chloride. The antimicrobial coating can be applied to the curable splint member by applying a solution, which includes 0.1 percent and 10 percent by weight the silane quaternary ammonium ion or salt thereof and an isopropyl alcohol solvent, to the exterior surface of the pad.

## Claims

### Claim 1

A method of manufacturing a splinting system comprising:
applying a solution, which comprises a silane quaternary ammonium ion or salt thereof and a solvent, to an exterior surface of a pad;
drying the pad;
enveloping layers of fiberglass cloth, which are coated with a water curable resin, with the pad to form a curable splint member;
applying the solution to an exterior surface of a metal foil pouch;
drying the metal foil pouch;
placing the curable splint member in the metal foil pouch; and
sealing the metal foil pouch;
wherein, the silane quaternary ammonium ion or salt thereof is between 0.1 percent and 10 percent by weight of the solution.

### Claim 2 (depends on 1)

The method of claim 1,
wherein, the solvent is isopropyl alcohol.

### Claim 3 (depends on 2)

The method of claim 2,
wherein, the isopropyl alcohol is between 30 percent to 90 percent by weight of the solution.

### Claim 4 (depends on 1)

The method of claim 1,
wherein, the silane quaternary ammonium ion or salt thereof is one or more of: 3-(trimethoxysilyl)propyldimethyloctadecyl ammonium ion, 3-(trimethoxysilyl)propyldimethyloctadecyl ammonium chloride, 3-(trihydroxysilyl)propyldimethyloctadecyl ammonium ion, or 3-(trihydroxysilyl)propyldimethyloctadecyl ammonium chloride.

### Claim 5 (depends on 1)

The method of claim 1 further comprising:
applying the solution to an exterior surface of a clamp configured to selectively seal or unseal the metal foil pouch.

### Claim 6 (depends on 1)

The method of claim 1, wherein
the pad comprises felted polypropylene fibers.
