BARRIER SHIELD METHOD AND APPARATUS FOR OPTICAL MEDICAL DEVICES

摘要

A barrier shield for optical-medical devices is disclosed which has an inner aperture defined by elastic material so as to form a seal adjacent to the optical portion of the device. The shield extends radially from the elastic material and may be supported by a frame. The elastic material permits movement of the shield about its position in relation to the optical-medical device so as to avoid impediment in the operation of the working ports. The shield is manufactured from inexpensive materials so as to allow disposal of the shield after use. The shield protects the doctor from infection by preventing backspray of body fluids through the working port of the optical-medical device from reaching the doctor. The shield also helps prevent reverse contamination of working devices which pass into the patient during endoscopy.
