Abstract
Abstract The present invention relates to a surgical drape having a first rectangular part (A) which is intended to cover a patient and a second rectangular part (B) which is joined to the first drape part (A) and which is intended to be placed over an anaesthetist's arch. In accordance with the invention, one short side of the first drape part has formed therein a cut-out (2) in the shape of a truncated V. The second drape part (B) has formed therein a similar cut-out (2), which is formed in the center of one long side of the second drape part. The first and second drape parts are joined together along the edges of the cut-outs. The invention provides a surgical drape which can be easily manufactured by machine and which is easily managed.
