Protective breathing apparatus incorporates a powered air pump which introduces potentially contaminated air from the atmosphere to the ‘process chamber’. The process chamber are composed of a filter and disinfectant solution such as soap, alcohol by adding the solution mixed with the contaminated air passes through the filter to catch a virus in the inlet air to separate the processed air and solution. Furthermore the processed air can be heated and/or be exposed to UV light, the air is then forced to pass through a disinfectant into a centrifuge. The centrifuge then spins the disinfected air forcing the air through a filter, the air then passes a mechanical filter resulting in purified air that flows through conduit means into a transparent plastic breathing hood containing the wearer's head. The hood is secured by a neck band around the wearer's neck. Newly purified air in the breathing hood is distributed and circulated throughout the hood's interior, the current of air holds the hood out of contact with the wearer's head. After the purified air has been inhaled and exhaled by the wearer, it is expelled through an exhaust port in the breathing hood. The exhaled air has potential to be contaminated. The exhaust air travels through conduit means back to the process chamber, this redirected exhaust air is purified before its release back into the atmosphere so no contaminates are expelled into the atmosphere. Optional provision is made for adjusting the temperature of the newly purified air for optimal user comfort, and for a plurality of breathing hoods to be supplied by a single air purifying device.

The above device can be stationary without the breathing hood. Similar to a dust cleaner, but it can kill the virus.

A personal protection system for providing a sterile barrier around medical/surgical personnel. The system may include a head unit over which surgical garment such as a hood or a toga may be suspended over. The surgical garment may include a sterile material and a shield configured to be disposed in front of the wearers face when disposed over the head unit. The shield may comprise an anti-reflective coating configured to reduce the glare observed by the individual through said shield. The head unit may comprises a light assembly that is disposed on the wearers side of the surgical garment, and an inner surface of said surgical garment may comprise a light reflective material configured to reduce the amount of light emitted from said light assembly that is reflected back toward the individual.

A safety hood (1), with a head strap (7) for fixation on the head (6) of a user of the hood, has features for adjusting the head strap (7) to different head sizes and/or head shapes. The respirator hood (1) has, further, a visor pane (4) and a flexible hood outer skin (8), which are connected with one another and of which the visor pane (4) is indirectly or directly fastened to the head strap (7). The visor pane (4) is fastened indirectly or directly to the head strap (7) exclusively in the area (10) of the forehead of the user of the hood.

The invention relates to a low pressure drop personal protection device for providing protection against a range of toxic industrial chemicals and chemical warfare agents and capable of being worn by a wide range of users. The device comprises: a flexible polymeric hood in which the polymer is selected to be impermeable to the toxic challenge molecules; a neck seal for sealing the hood about the neck;a half mask for providing connection for a canister; and a low pressure drop canister system for providing chemical protection. The canister may comprise a resiliently flexible, closed cell foam and monolithic activated carbons, the foam having holes slightly smaller than the size of the monoliths so that flow through the canister is through the monoliths. The monoliths may be the result of partially curing a phenolic resin to a solid, comminuting the partially cured resin, extruding the comminuted resin, sintering the extruded resin so as to produce a form-stable sintered product and carbonising and activating configurable the form-stable sintered product. They may be between 5 and 40 mm diameter, preferably 15 to 30 mm and 1-3 cm in length. Each monolith may have a square channel structure wherein the channel size is 100-2000μ and the wall thickness may be 100-2000 μm with an open area of between about 30 and 60%. It may have a surface area of at least 700 m2/g, may be activated to >30 wt % weight loss and may be impregnated with materials selected from metallic additives and triethylene diamine according to the anticipated challenge.
