Abstract
Abstract A surgical head drape of a single sheet of flexible material which is a barrier to bacterial migration provided with a pair of opposed and spaced apart side slits extending oppositely inwardly of both side edges to define a connecting tab portion integrally connecting a base sheet panel portion adapted to be inserted under the patient's head and covering the head end portion of an operating table with a turban sheet panel portion adapted to be wrapped around the patient's head with the turban sheet panel portion folded to overlie the base sheet panel portion during initial presentation (i.e., approach to the patient). The slits are dog-legged or jogged at the inner end portion thereof defining an offset connecting fold line therebetween and the drape is folded therearound to position the turban sheet panel portion on the base sheet panel portion with the leading edges of the base and turban sheet panel portions being offset so that the base sheet panel portion extends beyond the turban sheet panel portion. The drape is further folded to encourage aseptic handling during presentation and enabling it to be picked up and applied or positioned to drape the patient's head and the underlying head end portion of the operating table without the nurse having to reposition her hands on the drape so that she may therefore maintain complete control of the drape and thereby substantially reduce the danger of contamination.
