Problems solved by technology

Pharyngeal swab sampling is the easiest to popularize and has strong operability. Sputum is not always available, and the extraction of alveolar lavage fluid involves bronchoscopy, which is inconvenient to operate, and medical staff are more likely to be infected.

Embodiment 1

[0023] Such as Figure 2 ~ Figure 3 As shown, a viral nucleic acid enrichment sandwich structure is characterized in that: the sandwich structure 2 is a rectangular four-layer structure, including activated carbon fiber cloth A3, virus adsorption membrane A4, activated carbon fiber cloth B5 and virus adsorption membrane B6 from outside to inside , the surrounding edges of the activated carbon fiber cloth A3, the virus adsorption film A4, the activated carbon fiber cloth B5 and the virus adsorption film B6 are sewn together, and the surfaces of the virus adsorption film A4 and the virus adsorption film B6 are evenly distributed with several ventilation holes. In this embodiment, the activated carbon fiber cloth A3 and the activated carbon fiber cloth B5 can absorb water vapor, and are used to soak the virus adsorption membrane A4 and the virus adsorption membrane B6, so that they can enrich the viral nucleic acid. The air holes in the virus adsorption membrane A4 and the virus ...

Embodiment 2

[0028] Such as figure 1 As shown, a viral nucleic acid enrichment mask comprises a mask face body 1 and tension straps on both sides of the mask face body 1, the mask face body 1 includes a hygroscopic layer, a filter layer and a water blocking layer successively from the outside to the inside, and the hygroscopic layer Between the filter layer and the sandwich structure 2 described in Example 1, the sandwich structure 2 is located at the position where the mask face body 1 faces the mouth and nose.

[0029] The sandwich structure 2 has a length of 5 cm and a width of 3 cm.

Abstract

The invention relates to the technical field of virus detection, in particular to a virus nucleic acid enrichment sandwich structure and a mask. The sandwich structure is rectangular and comprises activated carbon fiber cloth A and a virus adsorption membrane A from outside to inside, the peripheral edges of the activated carbon fiber cloth A and a nitrocellulose membrane A are sewn together, anda plurality of vent holes are evenly distributed in the surface of the virus adsorption membrane A. The sandwich structure can be used for enriching virus nucleic acid, can be used as a common mask after being applied to the mask, and can also be used for enriching virus nucleic acid, while masks on the market can only block dust, bacteria, viruses and the like. After the mask is used, nucleic acid enriched in the mask is directly detected, operation can be simplified, and the infection probability of medical staff is reduced.

Description

technical field [0001] The invention relates to the technical field of virus detection, in particular to a viral nucleic acid enrichment sandwich structure and a mask. [0002] technical background [0003] Virus particles are very small, generally less than 0.3 microns in diameter. The masks currently used, whether they are medical masks (represented by various types of surgical masks of 3M Company in the United States) or ordinary civilian masks, are all made of textiles. Masks are widely used in hospitals and daily life. This is because wearing a mask can block the spread of liquid droplets in the mouth and nasal cavity, and can prevent dirty hands from accidentally touching the mouth and nose and bringing bacteria or viruses into the human body. [0004] Throat swabs are currently the most common way to collect samples from the oral cavity and nasal cavity. Pharyngeal swab sampling is the most convenient and operable method. Sputum is not always available, and the extra...
