Mask capable of detecting novel coronavirus pneumonia pathogens and using method

Abstract

The invention discloses a mask capable of detecting novel coronavirus pneumonia pathogens and a using method. The mask comprises ear hooks, a mask body and a breathing valve on the mask body; a detection chip is arranged in a breathing air passage of the breathing valve; a detection display module is arranged on the outer surface of the mask body; the detection chip is provided with a sample collection and reaction area; the sample collection and reaction area is coupled with a gold microwire electrode; the gold microwire electrode is connected with an antibody capable of capturing pathogens so as to form a working electrode; a reference electrode and a counter electrode are also arranged; the working electrode, the reference electrode and the counter electrode jointly form an electrode ofthe detection chip; the electrode, a current amplification circuit of the detection display module and the control function module are connected in sequence, and the control function module is connected with an indicating lamp and / or a digital display screen; the detection display module comprises a current amplification circuit, a control function module and an indicating lamp and / or a digital display screen. The method is suitable for sampling and detection of large-scale screening of new crowds suspected of novel coronavirus in a short time.

Description

Technical field: [0001] The invention belongs to the field of pathogen detection, and in particular relates to a mask capable of detecting novel coronavirus pneumonia pathogens and a use method thereof. Background technique: [0002] Viral pathogens cause millions of infections globally each year, causing severe morbidity and mortality in both developing and developed countries. Examples include West Nile, Chikungunya, Zika and Dengue in Brazil. The clinical features of 2019-nCoV infection are fever, dry cough, shortness of breath, low or low peripheral blood leukocytes, and inflammatory changes in chest radiographs. The World Health Organization (WHO) confirmed and named its pathogen COVID-19, a novel coronavirus belonging to the genus Beta, and declared it an international public health emergency on January 31, 2020. Viral pneumonia is a highly hazardous disease that seriously damages public health, especially the unknown new type of coronavirus pneumonia. [0003] Infl...

AI Technical Summary

Problems solved by technology

Although throat test sampling is simple and fast, it also has the following deficiencies: 1. Insufficient grasp of disease indications and retention time, resulting in low reference value of the results

2. The specimen collection site is not correct, and the secretions from the site of the lesion are not collected, especially the nasal test, the collection site is often shallow and does not reach the nasal vestibule

3. The operator lacks business knowledge and has insufficient grasp of operating standards and procedures

Fluorescence detection can have good detection limits, but can be expensive, or require more steps and equipment, such as immunomagnetic separation or nucleic acid amplification [13] , which increases the complexity of operation and analysis time; membrane strip method is cheap, simple and fast, and has been used for POCT detection of a series of viruses; colorimetric detection is usually used together with membrane strip method [14] , so it is difficult to achieve the required detection limit

[0008] Looking at the above-mentioned methods, a common feature is that the specimens are collected first, and then the two steps of detection are carried out. There are no reports or products that combine the two steps into one and integrate them into the mask.
