Embodiment 1

[0059] Preparation of sulfated rayon fabric

[0060] According to one embodiment of the present invention, sulfated rayon is prepared according to the following steps of the present invention. First, 60 mL of isopropanol was cooled on ice, and 0.2 g of MgSO 4 Water was removed by adding to isopropanol. Next, 240 mL of sulfuric acid, previously ice-cooled, was added to the isopropanol. Then, with a density of 70 g / m 2 A non-woven (non-woven) rayon fabric was cut into 17.5 cm x 22.5 cm rectangles and laid on a polypropylene mesh of approximately the same size. Next, the rayon fabric on the mesh was immersed in ice-cold acetic acid for 15 minutes. Then, the isopropanol / sulfuric acid mixture was poured into a polyethylene box (approximately 30 cm x 37.5 cm) placed on ice. Next, the rayon fabric on a polyethylene mesh was immersed in an isopropanol / sulfuric acid mixture for 5 or 10 minutes and rinsed first in cold isopropanol and then in cold isopropanol containing 3 grams of ...

Embodiment 2

[0062] Preparation of sulfonated rayon fabric

[0063] According to one embodiment of the present invention, the sulfonated rayon fabric is prepared according to the following steps of the present invention. First, a solution was prepared by adding 30 grams of sodium sulfate to 600 grams of distilled water, followed by the addition of 4 grams of CI Reactive Blue 21 dye (a sulfonated binding substance). Then, 30 grams of density of 70 g / m 2 A non-woven (non-woven) rayon fabric is added to the solution and gently agitated until uniformly submerged and wetted. Then, 12 g of sodium carbonate were added with stirring, and the mixture was kept at 30° C. for 35 minutes. Next, the temperature was raised to 70°C for an additional 60 minutes to produce a sulfonated rayon fabric (using CI Reactive Blue 21 dye as a binding substance). The sulfonated rayon fabric was then rinsed under running water until no free dye was eluted, and the sulfonated rayon fabric was allowed to dry.

Embodiment 3

[0065] Contains substances that disrupt the disease-causing ability of one or more than one human pathogen

[0066] Preparation of fabrics of one or more than one substance

[0067] According to one embodiment of the present invention, according to the following steps, the sulfated cellulose fabric prepared according to Example 1 or the sulfonated cellulose fabric prepared according to Example 2 is made to contain one or more substances other than the binding substances. An additional substance that destroys the disease-causing ability of one or more than one human pathogen. First, a sulfated rayon fabric was prepared according to the method disclosed in Example 1 or a sulfonated rayon fabric was prepared according to the method disclosed in Example 2 (using CI Reactive Blue 21 dye as a binding substance). Then, using the concentration of lg metal salt / 100ml water, through aerosol at 40μl / cm 2 Fabric (amount) Copper sulfate and zinc acetate, both divalent metal salts, were a...

Abstract

A dry sanitizing patch for use in decreasing the transmission of one or more than one human pathogen, the dry sanitizing patch comprising: a) a binding layer comprising 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; b) an adhesive layer connected to the binding layer, and comprising an adhesive suitable for reversibly attaching the dry sanitizing patch to a surface; and c) a backing layer removably connected to the adhesive layer to protect the adhesive layer until the patch is ready for use.

Description

[0001] References to related applications [0002] This application claims priority to U.S. Provisional Patent Application No. 61 / 180,085, filed May 20, 2009, entitled "Dry Sanitizing Patch for Decreasing Human Pathogen Transmission," and claims the title of Priority is given to US Provisional Patent Application No. PCT / US2008 / 068225 for "Devices and Methods for Decreasing Human Pathogen Transmission", the contents of which are incorporated by reference in their entirety in the disclosure of this application. Background technique [0003] There are various human infectious diseases that are thought to be transmitted in part by direct skin-to-skin contact between individuals, or by a person's skin contact with a contaminated object. Among these, human infectious diseases are infections of the human respiratory tract caused by bacteria, fungi and viruses. Examples of viruses that cause infectious disease (and related diseases) in humans include: influenza A virus (influenza), i...
