20040003818, Jan 8, 2004

Filed:

Mar 10, 2003

Appl. No.:

10/385981

Inventors:

David Padget - Stillwater MN, US
Leland Annett - Stillwater MN, US
Timothy Smalstig - Burnsville MN, US

International Classification:

A61F005/37

US Classification:

128/849000

Abstract:

A surgical drape manufactured or fabricated from a polymeric film having a low glare finish and a predetermined coloration for reducing the luminous intensity of light reflected from the surface thereof is provided. Such surgical drape thereby minimizes reflectivity therefrom, and thus eye strain and fatigue. The subject invention includes the use of colorants, dyes, pigments, etc. to form translucent polymeric surgical drapes that absorb a selected range of wavelengths from surface reflected light. More particularly, the use of coloring agents in combination with a textured surface yield a surgical drape possessing reduced luminance and glare, thereby mitigating eye strain and fatigue. The preferred range of reflected light, in order of preference, is 625-700 nm, 520-560 nm, 450-520 nm, 400-450 nm, 600-625 nm, and 560-600 nm.

International Classification:

A61B 19/08

US Classification:

128849000

Abstract:

An adhesive composition having dispersed therein a broad spectrum antimicrobial agent for use in medical applications, such as an adhesive for surgical drapes, wound dressings and tapes, is provided. The adhesive is composed of acrylic polymers, tackifiers and a preferred antimicrobial agent, diiodomethyl-p-tolylsulfone. The subject adhesive composition may be formulated as either an essentially solventless hot melt, or as a solvent based system wherein an emulsion of the antimicrobial agent and the removal of excess solvent is avoided.
