Abstract: A headwear having a selectively adjustable visor is disclosed. The headwear includes a crown for covering at least a portion of a wearer's head. A visor is attached to the crown and includes a visor cover disposed over a unitary visor body. The visor body has a first surface and an opposing second surface to define a uniform thickness. The visor body is configured with at least one slit formed therein. The at least one slit defines a proximal portion and a distal portion. The distal portion is transitional relative to the proximal portion between a first position and a second position. The slit allows the distal portion of the visor to adjust relative to the proximal portion, thereby to enhancing the visor appearance of the headwear and providing a better shade to the wearer.

Abstract: An apparatus and method for preventing contamination of the Post Anesthesia Care Unit of A Hospital by the use of a mask sealed to the patient's face and connected by a ventilator circuit to an airator that pulls a vacuum to exhaust the patient's expirations to the outside atmosphere. The disclosure also includes a "oxyvent" which is a tube adapted to be attached to an oxygen tank and to a patient to provide a higher oxygen ratio to the patient and to provide forced ventilation to a patient who has difficulty ventilating.
