Gas reaction device for lung cancer exhaled gas detection

Abstract

The invention discloses a gas reaction device for lung cancer exhaled gas detection, and relates to the technical field of medical equipment. The problem of patient sampling and transferring is solved. The device specifically comprises a mounting plate, bent rods are fixedly mounted at the front end and the rear end of one side of the mounting plate through bolts, grooves are formed in the middles of the arc-shaped tops of the two bent rods, sampling mechanisms are arranged in the grooves, and the same baffle is fixedly mounted on the sides, away from the mounting plate, of the arc-shaped outer walls of the two bent rods through bolts. The device can be integrally carried to a sickbed of a patient by arranging the rolling wheels, the connecting shafts, the connecting plates, the rectangular sleeves, the rectangular drawing pipes and the like, the rolling wheels roll in the bent rods, the positions of the horn pipes are moved, the pipe openings of the horn pipes are made to face downwards, and the rectangular drawing pipes are stretched, so that the device is convenient to use. The rectangular suction tube and the horn tube extend to the position above the mouth and nose of a patient, exhaled gas is transferred into the reaction body through the elastic tube, and inconvenience caused when the patient moves around for detection is avoided.

Description

technical field [0001] The present invention relates to the technical field of medical equipment, in particular to a gas reaction device for detecting exhaled gas of lung cancer. Background technique [0002] Lung cancer is a malignant tumor originating from the bronchial mucosa or glands of the lungs, with the fastest increasing morbidity and mortality, and one of the malignant tumors that threaten the health and life of the population. In the past 50 years, many countries have reported that the morbidity and mortality of lung cancer have increased significantly. The incidence and mortality of lung cancer in men are the first among all malignant tumors, and the incidence and mortality of women are the second. The etiology of lung cancer is still not completely clear, a lot of data show that there is a very close relationship between long-term heavy smoking and the occurrence of lung cancer. Existing studies have shown that the probability of long-term heavy smokers sufferi...

AI Technical Summary

Problems solved by technology

[0003] Traditional lung cancer detection methods mainly include: 1. Use of large-scale instruments: X-ray, CT, PET, etc., which are expensive and difficult for ordinary people to accept; 2. Sputum examination: the accuracy rate is very low; 3. Biopsy: invasive, usually CT 4. Routine exhaled gas detection: clinical application has not yet been seen, and it is still in the experimental stage. Gas chromatography (GC), gas-mass spectrometry, etc. are needed, but for patients with serious illness , it is necessary to transfer the patient to special gas detection equipment for operation and its cumbersome operation is not conducive to the rapid collection of samples
