A protective cover for an emergency worker oxygen tank has a rigid protective cover member with a knob protection portion and a tank attachment member. The tank attachment member is fixedly attached to the rigid cover member. The tank attachment member is capable of being securely attached to a portion of a standard oxygen tank or a portion of the frame supporting said oxygen tank used by emergency workers. The oxygen tank is commonly strapped onto the emergency worker's back via a standard rigid frame. The rigid protective cover member includes a knob protection portion that is appointed to extend around and over an adjustment knob portion of the oxygen tank to prevent damage and facilitate transport.

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.

A support frame for being used with a face mask includes a resilient transverse rod and a longitudinal extension longitudinally extending from a middle portion of the transverse rod and having a strip-shaped or belt-shaped pattern including two ends connected with the transverse rod in a way that a part of the transverse rod and the longitudinal extension combinedly define a hollow portion. Therefore, when a user wears the mask quipped with the support frame, the longitudinal extension and the transverse rod expand the mask outwardly, such that the mask won't be completely attached on the mouth and nose of the user, thereby effectively enhancing comfort of the user wearing the mask. Further, the support frame can be applied to any masks with a fold portion and can be reused. The support frame has a light and simplified structure having a small size to be conveniently stored.

An open type breathing-out particles capture and filtration device includes a mask having an air-in space defined between an upper edge of the mask and a user's face; a suction assembly including an air expelling pipe communicable with the air-in space and a fan; filtering materials located upstream of the fan; and a power supply driving the fan to rotate and produce a suction airflow. External air flowed into the mask via the air-in space and air breathed out of the user's nose and mouth is sucked by the suction airflow to pass through the filtering materials, so that air discharged from the air expelling pipe is clean air without any infection source. With the air-in space, an additional load applied to the mask by the suction airflow is reduced and contact areas between the mask and the user's face is also reduced, making the mask more comfortable for wearing.

An apparatus and method for providing a filtered air environment and streams of filtered air both in front of a wearer’s face at an angle to prevent contamination by pathogens and contaminants also supply filtered air to the nostrils and mouth, which also dilute any remaining particles. The device includes a blower element configured to direct a filtered airflow across a wearer’s face at an angle to push particles away and another stream of air to lead toward the nostrils and mouth to supply filtered air. The apparatus includes a fan or multiple fan elements to develop an airflow. A filter removes contaminants from the airflow and local environment of the wearer. Variations of a vent system have an intake conduit positioned close to the exhaust conduit, with or without an air deflector, to create a “microcirculation” that helps to capture the wearer’s exhaled particles and increases the filtration process.

A face mask including a base model of a mask body having a front side and a back side and defining an interior. The back side includes a face opening within which a portion of a user face including a nose and mouth can be inserted and encompassed. The face opening is defined by a perimeter and is modified to substantially correspond to contours of the user face based on scan of topographical facial features of the user face.
