Patent attributes
A mask suitable for protecting the face of a patient during surgery comprises a transparent plastic shield which includes a transverse cutout that provides access to the nose and mouth, and a vertical gap which runs from the cutout to the shield's perimeter. Padding affixed to the perimeter of the shield's underside provides a cushion between the shield and face. The padding is preferably arranged such that the mask can be installed or removed without dislodging tubing inserted into the patient's nose or mouth via the transverse cutout. An attachment mechanism secures the shield to the face. A warming hood may be coupled to the protective mask. The hood preferably comprises outer and inner layers, with an access point at which air can be introduced between the layers; perforations on the inner layer permit warm air to be dispersed onto the patient.
