Abstract
A surgical drape has an impermeable cloth with a window providing access to the surgical site. The cloth has two peelable impermeable films which are a continuation of one another and are sealed together by a heat weld making it possible to separate the films by peeling. The window is shared between the two sheets. The invention has application in surgical drapes used in operations.
Claims9
An operating drape having a window through which a device can be extended to a surgical site, said operating drape comprising
- a first impermeable film,
- a second impermeable film,
- a bond comprising a heat weld between a margin of a surface of said first impermeable film and a margin of a surface of said second impermeable film, said bond being strong enough to maintain said first film and said second film in extension of one another, and having a tear resistance small enough to permit said first film and said second film to be peeled apart, the window being shared between the first film and the second film, a border of said window being opened when said first film and said second film are peeled apart thereby permitting removal of said drape without dislodgement of said device.
