Repeatable wearable respiration detector based on graphene electronic nose

Abstract

The invention relates to a graphene electronic nose-based reusable breath detector, which includes a breath collection device, an elastic wearable, a left air intake filter box, a right air intake filter box, and a one-way breathable valve. The detector with this structure can not only use the graphene sensor to analyze and judge the abnormal smell produced by the user's breathing, but also the cell mutation and the stretching stress of the oral cavity converted into the change of electricity, so as to realize the abnormality of the user's health. Conditions, as well as the detection of respiratory conditions, and can be used for clinical large data sample analysis. At the same time, the accumulation of low-cost, high-throughput, and large-sample data is conducive to the discovery of new disease biomarkers. The detector provides users with a portable, non-invasive, fast, sensitive, accurate, cheap, and repeatable wearable The detection equipment can monitor the air externally, detect diseases including early cancer internally, and accurately perceive and store the user's health data, which has a wider range of applications.

Description

technical field [0001] The invention relates to the field of wearable medical devices, in particular to the detection of human breathing and saliva, and specifically refers to a reusable wearable breathing detector based on a graphene electronic nose. Background technique [0002] Diseases frequently interfere with our enjoyment of life and our physical health, and cancer seriously affects our quality of life and longevity. Currently commonly used detection methods for diseases and tumors have disadvantages such as relatively complicated and invasive, expensive, and delayed treatment. As a result, most cancer patients are diagnosed at an advanced stage when they are diagnosed, losing the opportunity for surgery or the best treatment, and the prognosis is poor. Therefore, early detection and early treatment are the most important links in cancer treatment. [0003] Smell the breath, debate the disease. Scientists discovered a long time ago that "patients with liver disease,...

Problems solved by technology

But at present, it is either in the laboratory stage, or there is no ready-made functional application product, and now there is no integrated solution for comprehensive application, so it is currently impossible to carry out industrial production and promote use on a larger scale
