| 20120272967 | Mask Structure and Compositions for Use in Decreasing the Transmission of Human Pathogens - A facemask structure for inactivating pathogens includes a facial contact layer that is benign to human skin followed by a subsequent interior layer and an outer layer including an anti-pathogenic material. In this manner, active, isolated anti-pathogen layers can be provided in a multilayer mask structure. For example, an important anti-viral mask structure uses one or a mixture of acids to create a low pH environment on the first inner (or outer hydrophilic layer) so that the virus laden droplets from, e.g., a sneeze, are absorbed into and away from the surface. Thus, for an infected wearer, two or more hydrophilic layers on the interior of the mask can protect the environment from an infected wearer. | 11-01-2012 |
| 20100330140 | DEVICES AND METHODS FOR DECREASING HUMAN PATHOGEN TRANSMISSION - A facial mask for use in decreasing the transmission of one or more than one human pathogen to and from a human wearer of the facial mask, the facial mask comprising a facepiece; where the facepiece comprises three or more than three layers; where one or more than one of the three or more than three layers comprises a fabric comprising one or more than one binding substance comprising one or more than one human pathogen binding group for chemically attaching the human pathogen to the binding substance; where the fabric further comprises one or more than one type of multivalent metallic ion or metallic salt; and where one or more than one of the three or more than three layers comprises a heat-moldable fabric. | 12-30-2010 |
