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.

Claims

1. A surgical drape comprising a polymeric film having a low glare finish and a predetermined coloration for reducing the luminous intensity of light reflected from the surface thereof, said surgical drape thereby minimizing reflectivity and potential eye strain.

2. The surgical drape of claim 1 wherein said energy absorbing polymeric film reflects light having a wavelength in the range of about 4,000 to 4,500 angstroms.

3. The surgical drape of claim 1 wherein said energy absorbing polymeric film reflects light having a wavelength in the range of about 4,500 to 5,200 angstroms.

4. The surgical drape of claim 1 wherein said energy absorbing polymeric film reflects light having a wavelength in the range of about 5,200 to 5,600 angstroms.

5. The surgical drape of claim 1 wherein said energy absorbing polymeric film reflects light having a wavelength in the range of about 6,250 to 7,000 angstroms.

6. The surgical drape of claim 1 wherein said low glare finish is a matted surface.

7. The surgical drape of claim 1 wherein said low glare finish is a textured surface.

8. The surgical drape of claim 1 wherein said luminous intensity is reduced by up to about 45%.

9. The surgical drape of claim 1 wherein said polymeric film comprises a polyolefin.

10. The surgical drape of claim 1 further comprising a coating of an adhesive composition overlying at least a portion of said polymeric film.

11. The surgical drape of claim 10 further comprising a release liner, said release liner overlaying said coating of an adhesive composition for selective removal therefrom.

12. The surgical drape of claim 11 further comprising an antimicrobial agent carried by said polymeric film, said antimicrobial agent being carried by said polymeric film on a side opposite said coating of an adhesive composition.

13. In a method of producing a surgical drape, the steps comprising:

(a) selectively adding coloration to a polymeric drape starting material;

(c) forming a surgical drape from the colored polymeric drape starting material so as to produce a translucent, energy absorbing polymeric surgical drape capable of reducing the luminous intensity of light being reflected from the surface thereof, thereby substantially eliminating eye strain.

14. In the method of claim 13, the further step of providing a low glare finish to at least one side of said translucent, energy absorbing polymeric surgical drape.

15. In the method of claim 14 wherein said low glare finish is a matted surface.

16. In the method of claim 14 wherein said low glare finish is a textured surface.
