The present invention relates to active respiratory protective face shield systems. More specifically, the present invention is directed to face shield systems comprising a substantially transparent lens having an upper visual chamber and a lower breathing chamber. The protective face shield systems have a generally open design so to not substantially contact the user's face. The lens configured to cover at least the user's nose and mouth. An input filter system module provides a positive pressure environment to a breathing chamber by the delivery of filtered air. The positive pressure is of sufficient magnitude so to produce an air barrier for substantially preventing environmental contamination, e.g., particulate matter, microorganisms, and the like, from entering the breathing chamber. Alternate embodiments further include an output filter system module for the evacuation and substantial filtration of the user's exhalation air to surrounding environment.

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.

A combined goggle and face mask includes a goggle body, a strap, a shield, and two retaining members. Either side of the goggle body is recessed with a receiving portion. The goggle body is provided with a lens. Either end of the strap is provided with a bracket to be coupled to the receiving portion. The bracket is supported by the receiving portion. The shield is coupled to the google body. The retaining member is coupled to the bracket. Because the bracket is received in the receiving portion, the bracket can be supported by the receiving portion, so as to offset the pulling force. First edges that are oblique edges and second edges each in the form of a curved corner of the bracket are supported by two oblique sides and two bent sides each in the form of a curved corner of the receiving portion.

A system and method for re-useable, self-locking, cinching, and bundling straps comprises wrapping a strap comprising: a plurality of teeth formed on a first edge of the strap, a plurality of teeth formed on a second edge of the strap, and at least one slit in the strap around an object; forming a loop around the object; inserting an end of the strap through the slit in the strap; and pulling the slack out of the loop.

A personal exhaled air removal (PEAR) system for removing/evacuating exhaled air from a vicinity of a patient is designed to remove the exhaled air during an exhalation cycle of a patient. The system is synchronized with a patient's breathing cycle for activating suction of exhaled air via at least one suction inlet, and the suction inlet is adjacent to the patient, possibly attached to the patient via an interface.

The containment of aerosols produced in dental processes and treatments is of notorious relevance since they represent a high risk of transmission of infectious diseases, such as viral flu or COVID-19. Medical personnel in the dental area, or others, are exposed to a high risk of infection by constant exposure to these aerosols and splashes. Consequently, it is providing a protective shield for odontological procedures that functions as a physical barrier avoiding contact of dentists, orthodontists and/or their technicians/assistants with aerosols and splashes that occur during dental treatments and procedures.

Embodiments of particle protection headwear apparatuses and use thereof are detailed herein. In general, embodiments of the present invention include a shield and a shroud which couple to, or are partially or wholly integral with, a hat. The shield extends downwardly from the hat and is typically embodied as part of the hat. Further, the shield is designed for a user to be able to look through it. The shroud is coupled to and extends downwardly from the shield and the hat. The shroud extends entirely around a perimeter of the hat to form a breathable barrier between particles and the user's head. The shroud may be removeable from the shield and washable.

The present application discloses an apparatus, comprising: a goggle, including a goggle frame and a protective lens installed in the goggle frame; a face mask releasably connected to the goggle; a detachable pivot-connection structure provided between two lateral sides of the goggle frame and the face mask, the detachable pivot-connection structure comprising a pivoting axis substantially parallel to a lateral direction of the goggle frame; and a detachable locking structure provided between the goggle frame and the face mask, the detachable pivot-connection structure configured to cooperate with the detachable pivot-connection structure to selectively lock the goggle frame and the face mask together.

A mask including: a body adapted to cover eyes of a wearer, the body having: an outer portion; a face portion; one or more padding parts; and two contoured recesses associated with the eyes; and a retaining part connected to the body, the retaining part being configured to retain the body to the wearer, wherein the one or more padding parts is located between the outer portion and face portion, and the contoured recesses are present in at least one of the or each padding part.

A face mask device utilizing a flexible sheet of material having three termini. One of the termini includes an aperture that serves as an anchor place in combination with spectacles worn by the user. The two remaining termini are used to tie the mask about the head of the user.
