A protective headgear system includes a support configured to engage the head of a user, a facial shield having an upper portion coupled to the support and a lower portion having a lower extremity, a flexible sheet coupled to the facial shield, a base carried by the support, a first microphone carried below the lower extremity of the facial shield and preferentially oriented away from the user, a second microphone carried by the base and preferentially oriented toward the user, a first audio generator capable of being sensed by at least one ear of the user, and a second audio generator including a loudspeaker carried by the base such that the loudspeaker is located below the lower extremity of the facial shield and is oriented for preferential sound energy delivery generally away from the user.
A system for improving efficiency in a medical facility includes one or more sensors configured to wirelessly obtain information from a medical procedure area and output a first signal related to the obtained information, a processor configured to survey the first signal and identify one or more descriptors in the signal, and an output configured to describe one or more changes related to operation of the medical procedure area based at least in part on the one or more descriptors.
A protective headgear system includes a cover including a substantially transparent facial shield, a sheet sealingly coupled to the facial shield around the cover's perimeter, the sheet including a substantially anterior portion including a first sheet material configured to act as a substantial barrier to the passage of air, and including a substantially posterior portion including a second sheet material configured to filter contaminants from air, and one or more seams between the first sheet material and the second sheet material, a flow restrictor configured to significantly create a flow barrier between the cover and the neck of a user for providing an interior volume, an air mover configured to draw some of the external air into the interior volume, a filter coupled to the cover, and one or more flow directors configured to direct internal air, including at least some exhaled air, toward the second sheet material.

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.
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.
