Abstract
A surgical drape support for use in eye surgery or other surgery, for maintaining adjustable support of surgical drapes above the patient's nose and mouth, creating a small tent into which oxygen is supplied by a hose, allowing the patient to breathe freely. With the front legs of the support placed between the patient's shoulders and the operating table the greatest stability is achieved and the rear legs find their best location as the support is adjustably positioned for height by raising or lowering the frame on its legs with the locking screws just loose enough for a pivoting motion. The knurled locking screws are tightened to maintain the prefixed position and four point stability of the instrument on the operating table, resulting in a more relaxed state of mind for both patient and surgeon.
