The present invention relates to a personal respiratory protection device, in particular, such a device comprising a respirator body having a periphery, a filter media, forming at least part of the respirator body, and a gasket, the gasket being located at the periphery and extending along at least a portion of its length.

Personal respiratory protection device

Augmented reality-based training systems that can dynamically construct and render AR content based on physical attributes of a user to train the user to correctly fit one or more articles of a personal protective equipment (PPE) onto the user's body. In some examples, an AR system includes a display and a computing device having a memory and one or more processors. The memory can include instructions that, when executed by the processors, simulate a fitting of PPE to a worker. The system can capture an image of a worker, select a digital model of the PPE, determine alignment of the PPE to the worker, and output for display augmented reality content that includes a composite image of the worker overlaid with the digital model of the PPE in accordance with the determined alignment.

Personal protective equipment training system with user-specific augmented reality content construction and rendering

A maintenance-free respiratorthat includes a mask harness and a mask body. The mask bodyhas at least one layer of filter mediaand has a perimeterthat includes an upper segment. The upper segmentincludes first and second concave segmentsthat are located, respectively, on first and second sides of a central plane, when viewing the mask body from a top view. A maintenance-free respiratorof this configuration is comfortable to wear and can provide a snug fit to a wearer's face, particularly beneath each of the wearer's eyes, while at the same time having an ability to improve compatibility with various protective eyewear.

Maintenance-free respirator that has concave portions on opposing sides of mask top section

A respirator that includes a harness and a mask body that is air permeable. The mask body has a sinus region and a primary filtering region and comprises at least one nonwoven fibrous webs The sinus region of the mask body exhibits a resistance to airflow that is greater than the primary filtering region. This resistance to airflow is achieved through an alteration of the intrinsic structure of the plurality of nonwoven fibrous layers in the sinus region without adding additional material to the mask body. The alteration of the intrinsic structure assists in preventing eyewear fogging.

Anti-fog respirator

A personal respiratory protection device comprising an upper panel, a central panel, and a lower panel, the central panel being separated from each of the upper and lower panels by a first and second fold, seam, weld or bond, respectively, such that device is capable of being folded flat for storage along the first and second fold, seam, weld or bond and opened to form a cup-shaped air chamber over the nose and mouth of the wearer when in use, wherein the upper panel has a graspable upper tab, the upper tab being graspable in use to open the device.

Respirator tab

A respirator that includes a harness and a mask body that is air permeable. The mask body has a sinus region and a primary filtering region and at least one nonwoven fibrous web. The sinus region of the mask body exhibits a resistance to airflow that is greater than the primary filtering region. This resistance to airflow is achieved through an alteration of the intrinsic structure of the plurality of nonwoven fibrous layers in the sinus region without adding additional material to the mask body. The alteration of the intrinsic structure assists in preventing eyewear fogging.

Example PPE fit systems are described that verify that a current fit of a PPE on a wearer is consistent with a previous fit test of the PPE on the particular wearer. During a fit test of a PPE, an image capture device captures an image of the wearer with the PPE that represents a verified reference for a fit of PPE of a same or similar type on the particular wearer. During a verification check, an image capture device captures an image of the wearer with the PPE. Visual features of the fit test image are compared with visual features of the verification image to determine whether the fit of the PPE on the wearer is correct. Differences between the visual features are alerted to the user, such as for correction, adjustment, or retest.

Respirator device

A method of fit testing includes providing a respirator; providing a sensor having a sensing element removably positioned substantially within an interior gas space of the respirator; providing a reader configured to be in wireless communication with the sensor; positioning the respirator over a mouth and a nose of a user while the sensor is positioned substantially within an interior gas space of the respirator; and observing respirator fit assessment data communicated from the sensor to the reader.

Fit-test method for respirator with sensing system

A personal respiratory protection device comprising a main body having a headband attachment portion, a headband attached to the headband attachment portion by a headband bond module, wherein the module includes first and second non-woven tabs adhesively bonded to opposing sides of an end of the headband, the side of the first tab opposing the headband bond side being welded to the main body.

Respirator headband

A personal respiratory protection device comprising a main body () carrying an exhalation valve (), the valve () having a grip region () which is grippable in use by the user, the grip region () being configured to indicate to the user that the valve () is to be gripped during opening, donning and doffing of the device.

Respirator valve

A personal respiratory protection device () comprising an upper panel (), a central panel (), and a lower panel (), the central panel being separated from each of the upper and lower panels by a first and second fold, seam, weld or bond, respectively, such that device is capable of being folded flat for storage along the first and second fold, seam, weld or bond and opened to form a cup-shaped air chamber over the nose and mouth of the wearer when in use, wherein the upper panel has a graspable upper tab, the upper tab () being graspable in use to open the device.

Various embodiments of a respirator and a method of forming a respirator are disclosed. The respirator can include a mask body having an upper panel, a lower panel, and a central panel disposed between the upper and lower panels. The mask body can also include a left attachment mechanism disposed between a left tab of the mask body and a left portion of at least one of the upper panel and the lower panel when the mask is in an open condition, and a right attachment mechanism disposed between a right tab of the mask body and a right portion of at least one of the upper panel and the lower panel when the mask body is in the open condition.
