Abstract

The invention provides a portable device for diagnosis of lung cancer, which comprises a balloon, a gas pump, a buffer gas chamber, a reaction gas chamber, an image collection and processing system and a control system; the balloon collects exhaled gas of a patient with suspected lung cancer to carry out the reaction with a pre-designed porphyrin sensor array (the sensor array for detecting lung cancer markers, if the lung cancer markers exist, the color of the sensor array is changed before and after the reaction) in the reaction gas chamber, the collection of images before and after the reaction is realized by controlling the image collection and processing system through the control system, the images are compared, the collected images are carried out with the pretreatment to obtain the differential images before and after the reaction, the differential images are further compared with data in an expert lesion database to obtain the detection result, and the detection result is finally displayed through a liquid crystal screen or a micro-printer, thereby judging whether the patient suffers from the lung cancer or not.

Description

technical field [0001] The invention relates to medical device technology, in particular to a portable device for diagnosing lung cancer through exhaled gas of a patient. technical background [0002] Primary bronchial lung cancer, referred to as lung cancer, is one of the most common malignant tumors in the world and a serious threat to human health and life. The World Health Organization (WHO) reported in 2000 that a total of 7.065 million people died of malignant tumors in the world in 1997, accounting for 12.6% of the death toll. Among them, lung cancer accounted for 19% of malignant tumor deaths, ranking first in the cause of malignant tumor deaths. It is estimated that there are about 600,000 new lung cancer patients every year in the world, and the incidence rate is obviously increasing in most countries. At present, clinically, common diagnostic methods for lung cancer include: X-ray detection, computerized tomography (CT), magnetic resonance tomography (MRI), sputu...
