Abstract
A facial protective device for use in surgery and examination, adapted to extend outwardly from the base of the nose and be removably fixed in position by adhesive. The device and its adhesive adequately support surgical draping in a manner such as to ensure free passage of oxygen to the patient. Incorporated with the device is an oxygen delivery system which directs the oxygen most advantageously to the patient. The device is intended for single use and is disposable.
Claims2
A protective device and breathing mask for use in opthalmic surgery comprising:
- a base formed generally in conformity with the bridge of a prospective patient's nose adjacent the zygomatic arch;
- a ridge extending from said base substantially centrally thereof;
- a pair of side panels extending from said base respectively on opposite sides of and structurally connected to said ridge and substantially forming two sides of a protective nose cover;
- a fluid plenum chamber within said device spaced substantially from said base;
- said plenum chamber being positioned approximately midway along said ridge;
- means for admitting air to said chamber;
- said chamber having outlets directed substantially downwardly from said ridge;
- means, operatively cooperating with said side panels, for removably securing said device to the face of a patient;
- said device having a greater dimension in a direction outwardly away from the face of a patient than in the longitudinal direction of the patient's face when said device is operably disposed on the patient;
- and
- said device being disposed substantially out of proximity with the eyes of the patient when said device is operably disposed on the patient.
