ABSTRACT:
BACKGROUND OF THE INVENTION
(1) Field of the Invention
The present invention relates to a filter capable of removing viruses such as influenza.
(2) Related Art Statement
As a means for removing the virus suspended in the air, a technique has been conventionally known to capture the virus with a filter and inactivate the thus captured virus with ultraviolet light. However, since the ultraviolet light is harmful against the human bodies, it is difficult to use such a technique in ordinary living spaces. In addition, the ultraviolet light is likely to deteriorate the material of the filter and any accompanying equipment. Further, although gauze masks are widely used in the ordinary living spaces to cope with the viruses such as influenza, such gauze masks cannot capture the viruses.
SUMMARY OF THE INVENTION
The present invention is directed to solving the above-mentioned conventional problem, and has been accomplished to provide virus-removing filters which can be used in the ordinary living space and effectively remove the viruses such as influenza virus.
The present invention has been accomplished to attain the above object.
A first aspect of the present invention is to provide a virus-removing filter using, as a virus-capturing body, at least one kind of
Streptococcus agalactiae
type II culture and Type II polysaccharide.
A second aspect of the present invention is to provide a virus-removing filter using, as a virus-capturing body, a substrate in which at least one kind of
Streptococcus agalactiae
type II culture and Type II polysaccharide is impregnated or kneaded.
removing filter using, as a virus-capturing body, a material with which at least one kind of
Streptococcus agalactiae
type II culture and Type II polysaccharide is covalently bonded.
A fourth aspect of the present invention is to provide a virus-removing filter using, as a virus-capturing body, a polymerized/copolymerized material that is obtained by polymerizing and/or which at least one kind of
Streptococcus agalactiae
type II culture and Type II polysaccharide is incorporated.
These and other objects, features and advantages of the invention will be appreciated upon reading of the following description of the invention when taken in conjunction with the attached drawings, with the understanding that some modifications, variations and changes of the same could be easily made by the skilled person in the art to which the invention pertains.
