Problems solved by technology

However, when the mask is discarded, the virus attached to the mask after use will adhere to the hands, and secondary infection will occur. Therefore, the mask does not have the effect of completely preventing infection.

no. 2 approach

[0060]In addition to virus inactivating particles (hereinafter also referred to as "first inorganic particles"), in the mask 100 of the second embodiment, second inorganic particles are held on the filter member 1 as other particles. In the second embodiment, the second inorganic fine particles together with the first inorganic fine particles form an inorganic fine particle assembly in which the inorganic fine particles are arranged two-dimensionally or three-dimensionally. In other words, in the second embodiment, the aggregate of inorganic fine particles including the first inorganic fine particles and the second inorganic fine particles is held on the filter member 1 . The same configurations as those of the first embodiment are assigned the same reference numerals, and description thereof will be omitted.

[0061] The second inorganic fine particles are bonded to the filter member 1 via the silane monomer or its oligomer, and the second inorganic fine particles are also bo...

other Embodiment approach

[0076] The masks 100 of the first and second embodiments have been described in detail above, but the present invention is not limited thereto, and other forms are also possible. For example, the shape of the mask 100 is not limited to figure 1 The type of mask shown. like image 3 As shown, the mask can also have a shape obtained by stamping using a hot press, and the present invention can also be used as Figure 4 Gauze masks as shown in.

[0077] The laminated filter elements 1 may have different functions. For example, by subjecting the outermost and innermost filter members 1 in the worn state to antibacterial and deodorizing processing, bad odor and bacterial growth can be suppressed. In the first and second embodiments, the mask main body is constituted by a plurality of filter members 1 . Certainly also can constitute mouth mask main body by a filter part 1. However, when a plurality of filter members 1 are stacked to form the mask main body 10, viruses can be in...

Embodiment 1

[0093] Commercially available copper(I) iodide powder (Wako Pure Chemical Industries, Ltd. Co., Ltd., Wako Class 1) was pulverized to an average particle diameter of 170 nm. Add pulverized copper (I) iodide fine particles to ethanol at 2.0% by mass, and then add tetramethoxysilane (manufactured by Shin-Etsu Chemical Co., Ltd., KBM-04) at 0.4% by mass, and pre-disperse using a homogenizer 5 minutes to make a slurry. Here, "average particle diameter" means a volume average particle diameter.

[0094] Next, add 20g / m 2 After dipping the rayon nonwoven fabric (manufactured by SHINWA Corp.) in the prepared slurry, the excess slurry was removed, and dried at 120° C. for 10 minutes to obtain a filter member 1 having a virus inactivation effect.

Abstract

Disclosed is a mask that can inactivate viruses adhered to the mask regardless of the presence or absence of an envelope and even under the presence of lipids or proteins. The mask can inactivate adhered viruses, and is characterized by being provided with: a mask body that has a member for mounting; and virus-inactivating microparticles that are supported on the mask body, have virus-inactivating properties, and comprise at least one compound selected from the group consisting of titanium (II) iodide, palladium (II) iodide, silver (I) iodide, copper (I) iodide, and copper (I) thiocyanate.

Description

technical field [0001] The present invention relates to a mask, in particular to a mask capable of inactivating attached various viruses with or without envelopes even in the presence of lipids and proteins. Background technique [0002] In recent years, there have been reports of deaths from viral infections such as SARS (Severe Acute Respiratory Syndrome) or bird flu. And now, due to the development of transportation and the mutation of the virus, the virus infection is spreading around the world. We are facing such an "infection outbreak" crisis, and it is necessary to formulate urgent countermeasures. In response to such a situation, the development of antiviral agents based on vaccines is also being rapidly advanced, but vaccines can only prevent infection by specific viruses because of their specificity. Moreover, it takes a very long time to prepare a vaccine against a new strain of virus. [0003] To prevent infection with these viruses, wearing a mask is recommend...
