Title: METHODS AND DEVICES FOR PROTECTIVE FILTRATION AND DELIVERY OF RESPIRABLE COMPOUNDS
Abstract:
The present invention relates generally to methods for the delivery of beneficial respirable compounds such as moisture, anti-inflammation compounds, anti-irritants, fragrances, aromatherapy compounds, and low dose medications slowly and continuously over time using a mask containing a thickened aqueous gel media delivery system combined with, supported by, and coating solid bodies inside the filter. The present invention also relates generally to methods for the removal of harmful industrial gasses from inhaled air using a disposable filtration mask containing a fluid filter media composed of a thickened aqueous gel that can be readily modified by means of additives to enhance its filtration properties for specific gasses individually, or in combination. The fluid filter media is combined with, supported by, and coats solid bodies inside the filter which optimize contact between the fluid filtration gel and the incoming air containing harmful industrial gasses. The present invention also relates generally to methods for the removal of hydrophilic bio-particulates from inhaled air using a disposable filtration mask containing a fluid filter media composed of a thickened aqueous gel that wets the bio-particulates, increasing their effective size and mass, and then retains them using the surface tension and viscosity of the thickened aqueous gel.
