A respirator for protecting against airborne particles includes a face gasket for providing a seal around the mouth and nose of a user, a frame attached to the gasket, a filter compression ring removably attached to the frame and a filter for filtering airborne particles from air. The filter is positioned between the frame and the filter compression ring. An eye protection accessory is attachable to the gasket. The respirator additionally includes a safety module that includes an air pressure sensor that can monitor the air pressure in the space bounded by the user's face and the filter. A processor analyzes the air pressure measurements obtained by the air pressure sensor and a vibration motor or a visual indicator. The processor can trigger the vibration motor and the visual indicator when the air pressure exceeds a predetermined threshold.

The hood has an air inlet and an air outlet and the air inlet, the mask air inlet, the mask air outlet and the air outlet are configured relative to each other to direct air flow across an inner surface of the transparent face shield to prevent or reduce fogging of the transparent face shield during inhalation and exhalation by a subject.

A full face respirator comprising a mask (10) having a transparent viewing portion (12) and a port portion (16), and exhalation port (22) disposed in said port portion (16), a face seal configured (14) to seal the mask (10) over a wearer's eyes, nose and mouth, in use, and an orinasal assembly (2) including a flexible, cup-shaped orinasal (2) having an orifice (2a) and being configured to fit over a wearer's nose and mouth, in use; wherein the orinasal assembly (2) further includes generally tubular connecting portion (24), integrally formed with and extending outwardly from the periphery of the orifice (2a), the connection portion (24) being shaped and configured to extend through the exhalation port (22) from the inner region to the outer region of the mask (10) and including an exhalation valve mount (28) for receiving a one-way exhalation valve (4).

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.

A face mask is provided. A face mask comprising a decorative skin, having a strap attached to an outer perimeter of the decorative skin, a respirator attached to a connection piece and utilizes a filter, the connection piece being attached to the decorative skin, a speaker and a microphone mounted to an interior of the face mask, an electronic transceiver module attached to the face mask and a power source attached to the face mask. The strap secures the face mask to a head of the user, the filter is connected to the respirator such that an air-tight seal is formed. The power source powers the speaker, the microphone, and the electronic transceiver module. The electronic transceiver module comprises a processor coupled to a computer memory and non-transitory computer readable media, the processor configured to transmit and receive signals from the electronic transceiver module and the speaker or microphone.

A gasket apparatus for use with a self-contained breathing apparatus, comprising an inner gasket portion adapted to form an airtight seal with a substrate such as a human head or face, wherein the inner gasket portion includes at least one type of connector device formed thereon or attached thereto; an outer gasket portion formed partially or completely around the inner gasket portion, wherein the outer gasket portion is adapted to receive at least one type of connecting device thereon for connecting one or more items to the outer gasket portion without disrupting the airtight seal formed by the inner gasket portion; and an interstitial space formed between the inner gasket portion and the outer gasket portion.

A pair of protective eyewear for securing a medical face mask on a face of a patient to prevent migration of the medical face mask about the face of the patient during a medical or surgical procedure. The protective eyewear may include a main body having a nosepiece and a pair of eye portions secured in the main body. The nosepiece may include a fastener defining a mask-receiving space for releasable receipt of a ridge of a medical face mask. The eyewear may additionally include one or more straps or other head securing structure, extending from the main body, to secure the eyewear to a head of the patient. Further, there is provided a system protecting eyes of a patient during a medical or surgical procedure and a method of securing a face mask to a face of a patient to prevent migration of the medical face mask about the face of the patient during the medical or surgical procedure.

A device for creating an air curtain protecting a human respiratory system is described. The device can be a hat and/or collar worn by a person and includes a constant or on demand flow of air that passes across a person's face to create an air curtain. The flow of air moving across the face blows airborne viruses away from a person's eyes, nose, and mouth. Another concept includes a glove that is outfitted with a device that purifies the glove. A battery could be mounted on a person's wrist or forearm with a small wire running down the glove. Likewise, the glove could be outfitted with UV light embedded on the surface or just underneath a permeable/top layer of the glove. Still further, the glove can carry electrical pulses aimed to kill viruses every ten seconds or so.

A facemask assembly can include an interior air filter that is replaceable and/or contains biocidal elements. The filter can capture exhaled H.sub.2O to activate silver ions creating a biocidal environment. In some embodiments, at least part of the facemask is made via additive manufacturing. A facemask frame assembly can create a pleated filter to increase surface area and bring the filter material closer to the mouth and nose. The facemask can include a facial skirt customized to the facial geometry of the wearer. The facemask can have a permanently sealed filter than can withstand boiling and autoclaving temperatures so the mask system can be sterilized without disassembly. In some embodiments, the facemask has a visible display of how many times the facemask has been sterilized. In some embodiments, the mask includes a RFID device that can transmit how many times the facemask has been sterilized.

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.
