Definitions
- This invention relates to masks which protect against biological hazards.
- Terrorists are thought capable of launching a major biological attack on civilian populations.
- Comfort and wearability yet minimizes the receipt and re-transmission of deadly or dangerous infectious agents.
- Comfort and wearability are especially important, given that users will need to wear the gear for long periods of time yet will lack the discipline which comes from military training.
- Biohazard protective gear is most commonly designed for military applications. United
- the device disclosed therein is a complete hooded respirator assembly form fitting to the
- HEPA filters for intake, one adjacent each cheek, as well
- hooded respirator also contains a clear eye
- the device disclosed therein would therefore be of limited use during a pandemic, or in the presence of any number of infectious biological warfare agents on the battlefield
- the '429 patent's hooded respirator also comprises a single volume enclosing the eyes, nose and
- this anti-fogging measure might not work. Since this single volume must enclose the eyes as well as the nose and mouth, it also acts as a
- the hood can be hot for the wearer, too.
- the present invention accommodates the goals of a civilian biohazard mask through a number of design features, appearing as recited in various instances and combinations in the appended claims.
- the ⁇ ivention provides HEPA filtering for both inhalate and exhalate.
- the eye volume is separate from the mouth and nose volume.
- the eye volume further includes water vapor-permeable, agent- impermeable, membranes to allow release of built-up water vapor, augmented with a passive air- circulation system.
- the mouth-nose volume is minimized, and measures are taken to maximize moisture discharge.
- the mask is sealed to the face using a combination memory seal/gel seal, and is suspended from the head
- Bidirectional filtering is of particular significance during a pandemic or localized epidemic.
- a highly transmissible and particularly deadly infectious agentpervades the environment civil authorities will likely impose quarantines.
- health care facilities will likely receive many infected people for care, creating another highly concentrated population
- FIG. 1 shows a perspective view of the mask of the present invention.
- FIG. 2 shows a frontal view of the mask of the present invention.
- FIG. 3 shows a side view of the mask of the present invention.
- FIG. 4 shows a view of the interior surface of the mouth-nose cone of the present invention.
- FIG. 5 shows a side view of the mask of the present invention, with the removable lens
- FIG. 6 shows a view of the underside of the mask of the present invention.
- FIG. 7 shows a perspective view of an alternate embodiment of the mask of the present
- FIG. 8 shows a perspective view of an alternate half mask embodiment of the present
- FIG. 9 shows a frontal view of the alternate embodiment of FIG. 8.
- FIG. 10 shows a frontal view of the alternate embodiment of FIG. 9.
- FIG. 1 a perspective view of one embodiment of the invention
- FIG. 1 shows a mask of the present invention
- the mask includes a lens portion 100, a mouth-nose portion 200,
- the lens portion 100 may be made of any clear lens material, preferably polycarbonate, and
- Lens portion most preferably polycarbonate that may flex during ordinary movement of the wearer.
- 100 also preferably includes two further structures (not shown) that function to remove moisture from the eye area.
- One is a water vapor-permeable, biological agent-impermeable membrane,
- TYVEK preferably TYVEK, and most preferably TYVEK of over one square inch surface area on each side
- the other is a one way air release valve in communication with the air in the eye
- Another feature of the mask that contributes to moisture abatement and anti-fogging is that
- the eye volume is sealed separately from the mouth-nose volume, to be discussed below.
- lens portion 100 may suitably accommodate prescription
- the mouth-nose portion 200 of the mask of the embodiment of FIG. 1 may be made of any suitable durable and impermeable material, and contains two main parts. These are the inhalation
- exhalation apertures i the embodiment of FIG. 1, these are separate sections, each with their own
- HEPA filters e.g., polyester/glass filters
- biocidal agents can be any biocidal agent.
- biocidal agents can be any biocidal agent.
- Such substances may preferably include elemental silver, and may also include silver
- compounds such as silver oxide, silver sulfadiazine and/or silver-hydrogel, or may include
- chlorhexidine and/or hypochlorite most preferably in powdered form.
- HEPA filter material of these types are generally available from supply houses such as 3M or
- the suspension portion 300 of the mask of the embodiment of FIG. 1 is of lightweight but
- the suspension portion 300 is made of a netting material. This can be in the form of the same
- netting can be in the configuration of a standard fishing net.
- Appropriate materials may include
- the suspension portion 300 need not be a complete head covering. It may
- netted straps configured appropriately to seal the mask to the face (described below).
- suspension portion 300 to the lens portion 100, as well as points of attachment 260 to the mouth-
- nylon straps may comprise any sufficient means to fasten the suspension portion 300 to the mask.
- seal 250 rests on the
- seal 250 helps define two separate non-communicating volumes within the
- the eye volume when seated on a wearer's face: the eye volume and the mouth-nose volume.
- the seal itself may constitute any number of materials, for example an adhesive, a memory seal
- the seal may also constitute a gel seal seated
- FIG. 4 there is shown a view of the inside surface 210 of mouth-nose
- the inhalation section 220 communicates with the interior of the mask through
- Valves 230 may be disk or dome valves concave toward the face which are
- valves 230 easily open to permit complete
- inhalation section 220 is associated in this embodiment with two inhalation valves 230, and involves
- the exhalation section 240 communicates with the interior of the mask
- Valve 270 may also be a disk or dome valve, this time convex toward
- valve 270 easily opens to permit
- the inhalation HEPA filter should preferably be selected to provide up to 1 square foot of total filtration surface.
- the exhalation HEPA filter has
- the inhalation HEPA filter because of the moisture content of exhaled breath.
- it can be preferably of somewhat less total filtration surface, and should have a more
