A rapidly deployable, pressure sealed, cough and sneeze aerosol, containment apparatus and a system to virtually eradicate the cold, the flu, and Covid-19. A face mask having a rigid first section configured to hold a filter and a pliable second section configured to fit on a person's face; a face mask seal formed on an edge of the pliable second section of the face mask; a curved surface on the face mask seal configured to fold inward to form a seal on the person's face when pressed on the person's face.

The filtration enclosure for ventilation bags is a manually operated respirator. The filtration enclosure for ventilation bags is adapted for use with a patient. The filtration enclosure for ventilation bags is a breathing assistance device that maintains a positive pressure within the lungs of the patient. The filtration enclosure for ventilation bags incorporates a bag valve mask respirator and a containment structure. The containment structure forms a protection space that encloses the bag valve mask respirator such that the bag valve mask respirator can operate while within the containment space. The containment structure is formed as a gas permeable structure. The containment structure forms a filter that filters microorganisms from the gas that flows through the boundary surface formed by the containment structure.

A self-contained breathing apparatus includes at least one air tank having a regulator, and a back plate configured to removably receive the air tank. The back plate has a plate having a tank engagement surface for engaging at least a portion of an air tank, a receiving cradle on the plate configured to receive the regulator of an air tank, and a locking mechanism associated with the cradle and/or the plate for releasably locking the regulator and/or the cradle relative to the plate. The locking mechanism has at least one locking member configured to move between a first locked position, wherein the locking member engages the regulator and/or cradle to restrict removal of the regulator and/or the receiving cradle from the plate, and a second unlocked position, wherein the locking member disengages from the regulator and/or the cradle to permit removal of the regulator and/or the cradle from the plate.

A wearable continuous positive airway pressure assembly for protecting a user from breathing airborne particles includes a continuous positive airway pressure machine that has an intake and an exhaust. A pair of shoulder straps is each coupled to the continuous positive airway pressure machine for wearing the continuous positive airway pressure machine on the user's back. An intake hose is fluidly coupled to the intake of the continuous positive airway pressure machine, a filter is fluidly coupled to the intake hose, and an exhaust hose is fluidly coupled to the exhaust of the continuous positive airway pressure machine. A face mask is fluidly coupled to the exhaust hose to receive the pressurized air from the exhaust hose thereby inhibiting the user from breathing ambient air.

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.
