Abstract: A respirator apparatus including an improved helmet or headgear construction with a unique shield including a protective lens and cuff attachment therefor. The protective lens is a thin clear plastic sheet designed to be used as a lens with a (PAPR) respirator and the cuff is an attached fabric or similar material designed to form a facial seal around the wearer.

Abstract: This invention is directed to a protective headgear system which includes a relatively light weight, substantially rigid, headgear structure which may include an internal, adjustable headband. The system includes at least one filter which is attachable to the headgear structure to cover the structure and a filter protector mounted thereon. A fan mechanism is mounted on the headgear structure to draw air into the headgear structure through the filter means. A power supply selectively powers the fan. A facial shield is attachable to the headgear structure to cover the face of the wearer to maintain non-contaminating conditions relative to the wearer. A flexible cuff or hood is attachable to the facial shield to enclose the lower opening of the lens and provides protection for the wearer through which air can be exhausted.

Abstract: A retracting system especially for use with operating room equipment and adapted to permit a vinyl tube to be removed from a storage spool to a desired length. The spool system is then locked into position so that the tubing is not retracted. By pulling slightly on the tubing, the apparatus retracts the tubing onto the storage spool for future utilization.

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.
