Problems solved by technology

[0003] At present, most of the commonly used exhaled gas samplers are only used for the collection of volatile organic compounds (VOC), and the versatility is poor
At the same time, the existing gas samplers are mostly used for sample collection and analysis in the laboratory, which is not easy to carry

Abstract

The invention provides a gas sampler. The gas sampler comprises a mask, a shell, a sampling tube, a gas supply unit and a pumping unit, wherein the mask is connected with the shell and communicated with the shell, the gas supply unit penetrates through the shell and is communicated with the mask, the pumping unit is arranged in the shell, and the sampling pipe is communicated with the pumping unit. The gas sampler can comprehensively collect volatile organic compounds and other tiny particles in exhaled gas, a doctor can conveniently analyze specific components and characteristics of the volatile organic compounds and other tiny particles and judge whether early-stage biological characteristics of common diseases exist or not, and therefore the diseases are prevented and treated in advance. Meanwhile, the gas sampler has relatively high universality.

Description

technical field [0001] The invention relates to the technical field of gas sampling and detection equipment, in particular to a gas sampler. Background technique [0002] Human exhaled air often contains thousands of volatile organic compounds (VOCs) and other tiny particles. Most of these exhaled gases come from the respiratory tract and lungs, and are an effective representation of the biological information inside the human body. By analyzing the specific components and characteristics of these exhaled gases, it can be used to judge whether there are early biological characteristics of common diseases, so that diseases can be prevented and treated early. The disease test differs from tests such as liquid and tissue biopsies that require blood or tissue samples. This disease detection modality offers a completely non-invasive solution that maximizes patient comfort. [0003] At present, most of the commonly used exhaled gas samplers are only used for the collection of v...
