Abstract
Abstract For the protection of the operating surgeon and of the medical staff when treating patients and during operations against the effects of secretions and blood of patients suffering from the immune deficiency disease AIDS, the facial mask consists of a mask blank with laterally attached fastening tapes, the mask blank of the facial mask being provided on the inside and on its upper edge, with a smooth or transversely folded relative to its longitudinal direction strip of foamed plastic with an adhesive surface of a coating with its self-adhesive agent, the adhesive layer being covered by means of a peelable protective sheet, so that the foamed plastic strip disposed on the upper edge of the mask blank of the facial mask which, facing the face, is provided with an adhesive layer and, due to its ready deformability, is, with its upper edge carrying the adhesive layer on the inside, made to adhere above the nasal area and onto the buccal region, so that a protection of the mouth and nose is ensured and the humid respiratory air cannot escape at the upper edge of the mask.
