Face mask devices, systems, and methods of use include a frame that holds a suitable filter material, including a face mask, over the user's face to form a seal and prevent unfiltered air from being inhaled through the nose or mouth of the user without first passing through the filter material. The frame is removably attached over the users face by, for example, adjustable straps. The frame may be adjustable in size to be suitable for use on user's having different facial sizes, shapes, and/or geometries.

A method of providing a virus and other pathogen protection for a person comprising providing a mask in which incoming air must pass across multiple surfaces constructed of multiple layers of a sticky material with a circuitous path to capture any airborne viruses and other pathogens irrespective of their size with the outgoing air taking a different path than the incoming air to prevent breathing moisture from interfering with the sticky capture and including a mouthpiece to prevent mask leakages.

A protective apparel system for use with a surgical helmet having a headlamp and including a protective apparel apparatus comprising a surgical garment, wherein the garment defines a sterile barrier between the wearer and the environment. The system includes a lens assembly adjacent to the surgical garment on the environment side and configured to cooperate with a coupling member for use with the headlamp. The lens assembly may include a control member and a lens, wherein the control member is be manipulatable by a wearer. The control member may be configured wherein manipulation by the wearer may reposition the lens of the lens assembly to adjust the direction and/or intensity of the light from the headlamp without breaching the sterile barrier.

A personal protection system including a helmet worn on the head of a user and a hood removably coupled to the helmet. The helmet may comprise a ventilation assembly, a chin bar and a control circuit. The chin bar may comprise a mounting device and a hall effect sensor mounted adjacent the mounting device. The hall effect sensor may be in communication with the control circuit. The hood may comprise a transparent face shield and a mounting element configured to removably couple with the mounting device of the helmet. The control circuit may be configured to receive a signal from said hall effect sensor indicating the coupling of said mounting element of said hood with said mounting device of said helmet.

A respirator including a facepiece with a transparent lens that is recessed radially-inwardly relative to an opaque frame of an opaque chassis of the facepiece. The respirator is configured to receive a vision-protecting module.

Face-worn accessories provide protection against air-borne particulates. A curved rigid or semi-rigid plastic frame with inner and outer surfaces surrounds an open window covered by a curved, transparent plastic shield. The upper and side portions of the frame include a compressible seal. The frame is worn over the mouth and nostrils of a wearer, with opposing side elastic members extending around the ears of a wearer, such that the compressible seal is conformal to a wearer's face. A gap at the lower portion of the frame is covered with filtration material, which may be provided by an existing removable, replaceable facial mask with the around-the-ear flexible bands of the existing mask being used to hold the entire accessory in position. The invention affords, greater visualization, improved protection with enhanced breathing, while allowing the user to chose their own mask or material for filtration purposes.

The present disclosure includes a retrofit sensor module for use with a protective head top with a helmet and a visor. The sensor module includes a sensor housing and an attachment mechanism. The sensor housing encloses a head presence sensor to sense when the protective head top is being worn. The sensor housing also encloses a position sensor to sense the position of the visor relative to the helmet. The retrofit sensor module further comprises an attachment mechanism secured to the housing. The attachment mechanism mates with a first hinge component of a hinge assembly in the protective head top to removably install the sensor module into the protective head top, wherein the hinge assembly allows the visor to move relative to the helmet.

A breathing mask is provided. The breathing mask is secured around the head of the wearer and includes a nose lifter disposed on the front face of the breathing mask. The breathing mask includes a hood, a pair of eye goggles, a mouth aperture, and a check valve disposed on the rear lace of the hood. The eye goggles are affixed to the hood with an elastic band attached in the rear of the hood. Moreover, the mouth aperture is disposed on the front face of the hood below the nose filter. The hood is secured to the head of the wearer by a zipper disposed on the rear face of the hood and an elastic band encircling a pair of side faces and a rear face of the hood. The elastic band encircling the hood provides an airtight seal to protect the wearer from airborne diseases and other hazards.

A wearable face covering may include a mask including a filter and a cap, wherein the cap is configured to prevent any gas passing through the filter in a first direction from exiting the mask in the first direction; and a face shield including a partially-transparent screen, wherein the face shield is pivotally coupled to the mask.

A protective shield is provided for covering a self-contained breathing apparatus (SCBA) mask or a full-face air purifying respirator (APR) lens to prevent damage and scratching. The shield consists of a die cut shape of thermoplastic sheet that duplicates the outline of the self-contained breathing apparatus mask lens and/or frame. The protective shield can be produced using various grades, colors and/or densities of material replicating limited visibility or blackout conditions. To protect the majority of the plastic lens, the shape of the shield includes a peripheral overlap onto the mask utilizing the SCBA lens frame. The shield can be attached to the self-contained breathing apparatus face mask by means of any of the following: bungee, hook, or elastic cord; all of which allows the shield to be attached or removed quickly. Many SCBA/APR training exercises require limited visibility. The invention can be used as an effective training tool to prevent light transmission and simulate extremely limited visibility.
