摘要： An apparatus and method for providing a filtered air environment and streams of filtered air both in front of a wearer’s face at an angle to prevent contamination by pathogens and contaminants also supply filtered air to the nostrils and mouth, which also dilute any remaining particles. The device includes a blower element configured to direct a filtered airflow across a wearer’s face at an angle to push particles away and another stream of air to lead toward the nostrils and mouth to supply filtered air. The apparatus includes a fan or multiple fan elements to develop an airflow. A filter removes contaminants from the airflow and local environment of the wearer. Variations of a vent system have an intake conduit positioned close to the exhaust conduit, with or without an air deflector, to create a “microcirculation” that helps to capture the wearer’s exhaled particles and increases the filtration process.

摘要： A gas mask, for use with a gas filter or with a demand oxygen system, includes an elastic mask body, a connector and a counter-support. The elastic mask body is configured to be placed over the mouth and the nose of a user of the gas mask. The connector is attached to the elastic mask body and is configured to fix a gas filter or an end piece of a tube in a mount of the connector. The counter-support is attached to the elastic mask body and has a contact area for a support projection of the connector. The connector and the counter-support are arranged such that a force exerted on the connector in a direction of the user acts on the contact area of the counter-support at least partially via the support projection. The support projection is integrated at the connector by manufacturing in one piece.

摘要： A respirator (10) having an oral-nasal unit (12) with a peripheral seal that seals around the nose and mouth of a wearer's face and having an inlet aperture (40) connectable to a supply of breathable air, and an outlet aperture (42). The unit having a rigid insert (106) with an exterior profile adapted to seat against a correspondingly shaped interior surface of the unit (12); an outlet conduit (112) with a tube adapted to extend through the exhale aperture (40) of the unit (12); and a wing portion (110) with a through aperture (122) registering with the unit's inlet aperture (40). The outlet conduit (112) having a bayonet connector (130, 132) that enables the unit to interchangeably and detachably connect to, a connector formed as part of an exhale aperture of a full-face mask, or of a harness assembly (102). The bayonet connector forms an airtight seal between the two.

摘要： A respiratory protection mask includes detachably connected main body and front cover. The main body includes a shielding member for shielding a wearer's mouth and nose, and has air outlet with air-outlet valve and air inlets with air-inlet valves. The mask is characterized in a guide structure and a limiting structure provided between the main body and the front cover. The guide structure includes corresponding slide rail and slide channel capable of guiding the front cover to move along a linear path parallel to a longitudinal section of the air outlet to assemble to the main body and cover the air-outlet valve. The limiting structure includes corresponding male and female fasteners that are detachably engaged with each other when the front cover is assembled to the main body, preventing the front cover from moving in an opposite direction on the linear path to separate from the main body.

摘要： The PAPR Frame is a low cost solution that allows the assembly of a PAPR Device from readily available off-the-shelf elements. To assemble the PAPR Device, a face shield is inserted into the PAPR Frame. To utilize the PAPR Device, a user inserts the visor of a hat into the PAPR Frame and wears the hat. The PAPR Device may further comprise tubing segments; the tubing segments are inserted into tubing apertures arranged through a top curved piece of the PAPR Frame. The PAPR Device may also further comprise one or two sound attenuation structures, which are used to dampen the potential noise generated by the air flow within the PAPR Device.

摘要： A self-contained breathing apparatus includes an air cylinder pressurized to about 5500 psi, wherein the air cylinder is compatible with infrastructure used in conjunction with the air cylinder. The self-contained breathing apparatus also includes a first regulator valve for reducing air pressure from the air cylinder to a predetermined level. A second regulator valve is also provided for reducing the air pressure from the predetermined level to a level suitable for use by an operator, wherein air is supplied from the second regulator valve to the operator via a mask. The self-contained breathing apparatus further includes a frame for supporting the air cylinder on the back of the operator. Other embodiments are described and claimed.

摘要： A high-pressure connector (10), for a fluid-communicating connection of a breathing gas source (200) of a respirator to a pressure reducer (110), includes a connector upper part (20) with a connector upper part duct (22) with an inlet opening (24) for the inflow of breathing gas from the breathing gas source (200). A connector lower part (30) has a connector lower part duct (32) with an outlet opening (34) for the outflow of breathing gas into the pressure reducer (110). The connector upper part (20) is fastened reversibly with a fastening interface (26) to a counter-fastening interface (36) of the connector lower part (30). The connector upper part duct (22) is in fluid-communicating connection with the connector lower part duct (32). A filter device (40) is arranged in the connector upper part duct (22) in at least some sections for filtering solid particles out of the breathing gas.
