Embodiment Construction

[0015] We now know that a sample of normal human breath typically contains over 200 different VOCs, most of them in picomolar concentrations. The types and contents of these compounds are closely related to the metabolism in the body. When some organs in the body are abnormal (that is, lesions), new compounds will be produced in the body or the amount of existing compounds will change. By detecting the changes in the type and amount of organic matter in these breaths, we can make a diagnosis of diseases (such as lung cancer, tuberculosis, breast cancer, organ transplant rejection, etc.) based on pattern recognition methods such as artificial neural networks.

[0016] Take lung cancer, for example.

[0017] Lung cancer is one of the most common malignant tumors in the world, accounting for 16% of all malignant tumors and 28% of malignant tumor deaths. At present, the 5-year survival rate of diagnosed patients is only 14.1%, and 60% of patients die within 1 year after diagnosi...

Abstract

The invention discloses a medical breath testing device which has the advantages of low testing cost, simple process, short time, accurate result and wide application. The device comprises a sample introduction port, a sampling pump, a six-way valve, a gas carrying cylinder, an adsorption tube, a chromatographic column, a surface acoustic wave detector and a data process system, wherein the six-way valve is respectively connected with the sample introduction port, the gas carrying cylinder, a first end of the adsorption tube, a second end of the adsorption tube, the sampling pump and one end of the chromatographic column; the other end of the chromatographic column is connected with the surface acoustic wave detector, the output end of which accesses into the data process system. The invention further discloses a testing method utilizing the device.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a medical breath detection device and a detection method using the medical breath detection device. Background technique [0002] In the era of Hippocrates in ancient Greece, doctors knew that by detecting the smell of patients' exhaled breath, they could assist in the diagnosis of diseases. In eighteenth-century France, Lavoisier - the pioneer of modern chemical analysis - was the first to analyze exhaled breath, proving that it contained carbon dioxide. Modern breath testing began in 1971, when Nobel laureate Linus Pauling discovered that normal human breath contains very low concentrations of many different volatile organic compounds. However, these techniques are currently only used by individual experts, and have not been widely used in medical practice. This is because the detection of changes in the type and amount of organic matter in the breath can o...
