Patent ID: 8361263

Claim:
A method for avoiding contamination of one or more electronic image display surfaces during a medical intervention performed in an operating theatre, comprising: continually providing a transparent and clean protective film over the one or more image display surfaces in the operating theatre while allowing the one or more image display surfaces to be observed during the medical intervention, including forming the film as a sheet with sufficient length so that different portions of the same sheet can be sequentially positioned over the one or more display surfaces thereby allowing a user to repeatedly cover and protect the one or more display surfaces multiple times with different clean portions of the sheet during the medical intervention; providing a reel, positioned adjacent the one or more display surfaces; rolling the sheet onto the reel for storage and for sequentially dispensing portions of the sheet from the reel to repeatedly cover the one or more display surfaces with clean portions of the sheet; providing a receiving device positioned adjacent one of the one or more display surfaces, and spaced away from the reel so that portions of the sheet extend between the reel and the receiving device, positioned to cover the one or more display surfaces; and rolling used portions of the sheet onto the receiving device; wherein the transparent and clean protective film is positioned at a fixable distance in front of the image display surfaces such that the protective film and the image display surfaces are not in mutual contact during the continually providing step.
