Filed:

Oct 10, 2001

Appl. No.:

09/975646

Inventors:

David B. Padget - Stillwater MN
Leland W. Annett - Stillwater MN
Timothy P. Smalstig - Burnsville MN

Assignee:

Medical Concepts Development, Inc. - Woodbury MN

International Classification:

A61B 1900

US Classification:

128849, 128853

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:

A61B019/00

US Classification:

128849, 128853, 128854

Abstract:

The invention comprises a surgical drape formed of a sheet material having a periphery and with a particular type of aperture spaced from periphery. The invention further comprises a method of using the drape. The aperture has a dominant portion and at least one subordinate portion. At least one subordinate portion of the aperture radially extends from the dominant portion. An adhesive layer may underlie an area surrounding the aperture.

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.

International Classification:

A61B 1900

US Classification:

128849

Abstract:

A configuration of surgical drapes for convenient dispensing and handling from a container. The configuration includes a continuous rolled length of surgical drapes having opposing major and minor longitudinal edges. Each drape of the continuous roll is separable from adjacent drapes by longitudinally spaced apart lines of weakness throughout the continuous length of surgical drapes. The continuous rolled length of surgical drapes includes an adhesive strip adjacent the major longitudinal edge of the continuous rolled length of surgical drape. The adhesive strip in turn carries a removable release liner thereover which preferably partially overhangs the adhesive strip. The continuous rolled length of surgical drapes further has an accordion pleat fold to thereby reduce the stored and dispensed width of each drape of said continuous length of surgical drapes.
