<p>A barrier shield (10) for optical-medical devices is disclosed which has an inner aperture (50) defined by an elastic material so as to form a seal adjacent to an optical portion of the device. The shield (10) extends radially from the elastic material and may be supported by a frame. The elastic material permits movement of the shield about its position with respect to the optical-medical device (12) so that operation of working ports is not impaired. The shield is manufactured from inexpensive materials so as to encourage disposal of the shield after use. The shield prevents infection of a physician by preventing backspray of bodily fluids through an optical-medical device working port (32) from reaching the physician. The shield also helps prevent reverse contamination of working devices passed into the patient during endoscopy.</p> |
