ABSTRACT:
An air flow and filtration control system in the form of a headgear which is worn by a physician during a surgical procedure, a technician during an assembly process, or any other user wherein controlled air flow and air filtration is required or desired. The flow-through system includes a relatively rigid, open frame, skeleton headgear structure which substantially surrounds the head of the wearer. A fan is mounted in the headgear structure. The fan is positioned to move air through ducts formed in the headgear structure. A shroud (or hood) is draped over and attached to the headgear structure in such a fashion as to completely cover the headgear structure and to cover at least a portion of the wearer in order to maintain sterile or controlled conditions relative to the wearer. The shroud includes filtration areas which may encompass the entire shroud. The filtration areas may be disposed adjacent tot he fans when the shroud is placed over the headgear structure. A relatively planar transparent screen or "window" is provided at the front of the apparatus for substantially undistorted viewing. Typically, the transparent screen is mounted in the shroud and is removable therewith. A suitable power supply, such as a battery pack or the like, is used to selectively power the fans. It is anticipated that at least the shroud (and the components mounted thereto) will be disposable.
