Hazardous Material Body Cover Patents (Class 2/457)
  • Patent number: 12257819
    Abstract: In one embodiment, a thin, lightweight, flexible, strong multi-layer barrier fabric is provided that offers extended breakthrough time against hazardous materials. The multi-layer barrier fabric is arranged as a layer stack that includes an inner layer of facing fabric, an adsorbent layer of adsorptive fabric, a barrier layer of low-permeability fabric and an outer layer of facing fabric. The facing fabric provides tensile strength. The adsorptive fabric and the low-permeability fabric interact synergistically. The barrier layer improves capture effectiveness of the adsorbent layer by both slowing down the hazardous material to increase its residence time in the adsorbent layer and decreasing the escape probability of stray molecules of hazardous material that are not initially intercepted by the adsorptive fabric. The adsorbent layer improves barrier effectiveness of the barrier layer by reducing the concentration of hazardous material challenging the low-permeability fabric of the barrier layer.

  • Patent number: 12213542
    Abstract: A system pump-conditions a garment worn about a torso of an individual. A circulation array within the garment and a pump array circulate a fluid within an interior space between the garment and the torso. The pump array exerts a negative pressure on the circulation array to circulate the fluid generally from a head opening at a top portion of the garment, into the interior space, then through the circulation array, then out of the garment. The pump array exhausts the circulating fluid down and away from the torso. The moving circulating fluid draws heat and humidity from within the garment and directs same away from such individual to cool and comfort same. The moving circulating fluid also draws a cooling and comforting breeze about the head of the individual.

  • Patent number: 11864608
    Abstract: A novel mosquito shield for protection against mosquitos and other types of insects. The mosquito shield combines a protective netting with a memory foam material that provides comfort to the user/wearer. The memory foam, or alternative material, is connected to the mesh 5 in a square, waffle like, pattern to form the protective mosquito shield. The thickness of the memory foam creates distance between the protective netting and the user's skin. This then increases the effectiveness of the protective mosquito netting because the mosquito's proboscis (needle for sucking blood) can no longer reach the wearer's skin.

  • Patent number: 8800068
    Abstract: An air ventilated protection suit includes an air input port, and a flat air duct connected to an inner end of the air input port. The flat air duct has hoses provided therein to separately extend in directions along which air is delivered to a whole interior of the protection suit. The hoses keep the flat air duct in an always unimpeded state, and respectively include an axially extended spiral cut, such that air supplied into the hosts pushes open the spiral cuts to flow from the hosts into the flat air duct via the push-opened spiral cuts. The protection suit also includes an inspection port to allow an air-tightness inspection of the protection suit before a wearer entering into a working environment; and an air-guiding case fitted around each pressure relief valve provided on the protection suit to provide a space for air released from the pressure relief valve.

  • Publication number: 20140182050
    Abstract: The invention relates to a functional protective material, in particular having a protective function with respect to chemical poisons and/or biological toxins and/or chemical and/or biological hazardous materials, such as warfare agents, wherein the functional protective material has a multi-layer structure that comprises a planar, in particular textile, substrate material and a membrane that is associated with the substrate material, in particular connected to the substrate material, wherein the membrane in itself is permeable to air and water vapor and therefore is provided with a plurality of micropores preferably distributed substantially evenly over the membrane surface. According to the invention, an operating parameter of the membrane can be changed in such a way that the membrane assumes two different operating states, wherein in the first operating state the micropores of the membrane are open and in the second operating state, the micropores of the membrane are at least predominantly closed.

  • Publication number: 20140173814
    Abstract: Nonwoven safety garments are described. Features of the stitching of some embodiments limit the number of particulates emitted from seams between cut edges. Attachments features may be included on the garments to enable secure, external attachment of measuring equipment. Doffing features, such as loops, are provided to help the wearer safely remove the garment, either by helping her pull off part or all of the garment or by starting to separate closure devices. In some embodiments, a repositionable closure on a neck flap covers the neck up to the bottom of a face mask or respirator, and a grasping tab helps the wearer safely open the repositionable closure and the neck flap.

  • Publication number: 20140059749
    Abstract: A protective garment comprising a plurality of layers integrated or bonded in a complementary manner protects wearers such as emergency responders against multiple hazards often present in a response area. The layers include a toxicity barrier adapted for visual contrast with toxic substances, such that the toxicity is barrier responsive to toxic substances by varying a response to an optical signal such as a UV light. An impact layer is responsive to projectiles by controlled deformation, such that the controlled deformation prevents passage of the projectile, as EMT response areas are often unsecured crime scenes where firearms may be present. Also, an absorbent layer is responsive to expelled fluids of the wearer such as perspiration, in which the absorbent layer is adapted for unidirectional diffusion of fluids so that moisture does not remain in contact with the skin of the wearer and cause discomfort, irritation, and thermal imbalance.
