An article of manufacture for providing a mask fixer to prevent air leakage at the edges is disclosed. The mask fixer includes a face piece and one or more components coupled to the face piece. The face piece includes a central aperture, an exterior surface, and an interior surface. Features, such as a nasal reinforcer, a flange, and/or a sealing loop, may be added to different parts of the face piece to form different embodiments of the mask fixer for different applications. In some embodiments, the mask fixer is used by releasably wearing it outside or inside a surgical or cloth mask to reduce air leakage at the edges. In other embodiments, the mask fixer includes a flange around the central aperture of the face piece. A surgical mask, a cloth mask or a filter is wrapped and fixed around this flange using a band or a snapping mechanism. As such, the mask fixer is integrated with a filter or a surgical or cloth mask to form a new face mask. This new face mask would diminish air leakage at its edges. In all embodiments, the mask fixer is reusable after it is cleaned and sterilized.

A face mask assembly includes a face mask is comprised of a particulate filtering material to filter air being breathed by a user. The face mask has a mouth opening extending through the face mask to expose the user's mouth when the face mask is worn to facilitate eating and drinking. A flap is movably coupled to the face mask and the flap is positionable in a closed position having the flap covering the mouth opening to filter air breathed by the user. The flap is positionable in an open position to facilitate the user to eat or drink. A first mating member is coupled to flap and a second mating member is coupled to the face mask. The first mating member is releasably mated to the first mating member when the flap is in the closed position for retaining the flap in the closed position.

A voice transmitter assembly for enhancing verbal communication for a user wearing a face mask includes a clip that has a first member which is biased against a second member to engage a face mask. A microphone is coupled to the second member of the clip to capture words spoken by the user. A speaker is coupled to the first member of the clip to emit audible sounds to a listener. The speaker is in communication with the microphone thereby facilitating the speaker to emit sounds captured by the microphone. In this way the speaker can enhance the listener's ability to hear the words spoken by the user.

An ultraviolet (UV) germicidal irradiation system comprising: a light emitting diode (LED) disinfecting face mask comprising: a flexible mask body having a front surface and a back surface; a flexible printed circuitry (FPC) sheet disposed within the flexible mask body, the FPC sheet having a plurality of LEDs adapted to emit UV light, the plurality of LEDs facing the front surface; a vibration sensor electrically connected to the FPC sheet, the vibration sensor being adapted to detect vibrations; a UV-reflective layer disposed behind the FPC sheet, the UV-reflective layer being adapted to reflect the UV light; and a light diffusion layer disposed in front of the FPC sheet, the light diffusion layer being adapted to scatter the UV light; and a control module comprising: a central processing unit (CPU), an LED driver, and a power source; the CPU being in electrical communication with the LED driver and the vibration sensor.

A face mask includes a space formed therein by a peripheral wall extending from the periphery of the space. At least one first path and at least one second path are respectively formed in the space so that outside air enters into the space via the at least one first pat, and air in the space is released from the space via the at least one second path. The face mask covers a large area of the wearer's face to reduce foreign objects from entering into the wear's body so as to reduce the chance of being infected.

A fold flat personal respiratory device comprising: a generally planar central panel (10) including a layer of filter media and having opposing first and second side edges (12a, 12b) and first and second end edges (11); a first side panel joined to said central panel (10) along said first side edge (12a); a second side panel joined to said central panel (10) along said second side edge (12b); the device being manually configurable from a folded configuration in which said side panels (12a, 12b) are substantially parallel to a planar surface of said central panel (10) and an operational configuration in which said central (10) and first and second side panels (12a, 12b) form a cup-shaped respiratory chamber; the device further comprising a rigid or semi-rigid endoskeleton member (36) mounted along a planar surface of said central panel (10) and extending between said first and second side edges (12a, 12b) and/or said first and second end edges (11).

A patient safety shield, and its method of use, features a deflector shield that closes gaps between the bottom profile of safety eyewear worn by the patient and the patient's cheek area. The deflector shield, when positioned, oriented, and profiled across the bridge of the patients nose and under the patient's eyewear, deflects fine infectious and or injurious debris, which originates in the patient's oral cavity, from being ejected off moving parts of dental tools during a dental procedure. The deflection by the deflector shield prevents potentially infectious or injurious debris from reaching and harming the eyes of the patient that may enter through the bottom gaps.

A coupling device for a mask test means is disclosed. Provided according to an embodiment of the present invention is a coupling device for a mask test means, comprising: a pressing member which can receive a first member of a mask test means on one side thereof and can move up and down; and a support member which can receive a second member of the mask test means on one side thereof and is disposed below the pressing member, wherein the support member includes a lower member having a perforation means for forming a perforation in a mask, and the pressing member includes an upper member into which at least a portion of the perforation means can be inserted.
