摘要： An air delivery system for delivering a pathogen-free airflow can include an air intake manifold, a sterilizer unit with a tank and at least one ultraviolet (UV) unit, a cooling unit with at least one cooling manifold and at least one heat exchange unit, and a user output. The air intake manifold, the tank, the at least one cooling manifold, and a user output can be in fluid communication in that general order. The at least one ultraviolet (UV) unit can be mounted within the tank, with the at least one UV unit configured to generate ultraviolet light to promote killing of pathogens. The at least one heat exchange unit is configured to cool the outbound air flow to a temperature suitable for breathing by a user and to heat an incoming air flow in the air intake manifold.

摘要： A blower assembly for a powered air-purifying respirator (PAPR) assembly includes: a lower housing; an upper housing connected to the lower housing, such that the upper housing and the lower housing collectively define a first interior cavity; a filter configured to filter ambient air drawn into the blower assembly; and a fan. The upper housing and the filter define a pathway for a flow of air into the first interior cavity. The fan is positioned in the first interior cavity such that, when the fan is activated, ambient air is drawn into the blower assembly and travels along the pathway into the first interior cavity for subsequent delivery out of the blower assembly. The lower housing defines an outlet port for directing breathable air out of the blower assembly for delivery to a user (e.g., via a breathing tube interconnecting a headpiece and the outlet port).

摘要： A face mask assembly includes a face mask is comprised of a particulate filtering material to filter air being breathed by a user. The face mask has a mouth opening extending through the face mask to expose the user's mouth when the face mask is worn to facilitate eating and drinking. A flap is movably coupled to the face mask and the flap is positionable in a closed position having the flap covering the mouth opening to filter air breathed by the user. The flap is positionable in an open position to facilitate the user to eat or drink. A first mating member is coupled to flap and a second mating member is coupled to the face mask. The first mating member is releasably mated to the first mating member when the flap is in the closed position for retaining the flap in the closed position.

摘要： A bayonet connector (112, 128) suitable for connecting a filter cartridge (72) or an air supply tube to a respirator (10, 14). The bayonet connector (112) has a tubular male part (112) and a female part. The male part has a tube (114) with two or more lugs (130, 132) formed on it, which engage with engaging ribs (136, 138) located on an interior sidewall of the female part (128), or vice versa. The lugs (130, 132) and their corresponding engaging ribs (136, 138) are located at different axial positions.

摘要： A breathing device related to the field of personal protective equipment and wearable technology that can be cleaned and sterilized so that it can be used repeatedly is disclosed herein. The device is configured to surround the mouth and nose of the user, and in some embodiments, it surrounds the eyes. The perimeter of the device can be comprised of a stretchable material that conforms to the contours of the user's face so that it provides an adequate seal, and in doing so, ensures that all or most of the air flowing through the device occurs through its air filtering regions. The filtering region is configured so that filtering material can be mounted to the device and replaced when needed. This filtering region is also configured so that a negative pressure seal test can be performed. Various embodiments of the device exist that enhance its capabilities from its most basic form. For example, in some embodiments, wearable technology is mounted to the device, is connected to the device, or is embedded within the device. This technology can include, but it not limited to sensors, microprocessors, cables, wires, actuators, soft robotic or soft machine materials, energy supply systems, and smart materials.

摘要： Embodiments relate generally to methods and systems for refreshing filter media within a respirator and indicating end of service life for the filter media. A respirator may include a rollable filter media configured to be refreshed by rolling the filter media onto a roller. A rolling mechanism may rotate the roller, allowing for a fresh section of filter media to be placed in the air path of the respirator. The rolling mechanism may be controlled automatically by a motor and/or manually.
