[0002] Sputum contains mucus, inhaled dust, various inflammatory cells, necrotic and sloughed mucosal epithelial cells from the respiratory system, necrotic tissue, bacteria, viruses, and other pathogenic substances. These pathogenic microorganisms are transmitted through the respiratory tract and can cause human disease. In particular, the sputum of tuberculosis patients contains large numbers of bacilli, which are highly contagious. Tuberculosis is a cause of lung cancer, which ranks first in the incidence of malignant tumors. Common clinical manifestations of lung cancer include coughing up sputum and hemoptysis. According to surveys, the incidence of tuberculosis remains high.

[0003] However, the existing portable sputum collector has a slow sputum collection speed, the collection bottle has low strength and the sputum sampling effect is not good enough, and it is difficult to clean the sputum after use; therefore, it does not meet the existing needs. We have proposed a portable sputum collector for respiratory medicine. Utility Model Content

[0010] Preferably, the lower end of the guide rod is completely in contact with the upper surface of the lower cover, and the guide rod and the lower cover are fixed by screws.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model provides an outer shell and an inner shell and a vacuum chamber between the outer shell and the inner shell. By utilizing the outer shell and the inner shell, the strength of the collection bottle can be increased. By utilizing the vacuum chamber, the influence of the external temperature on the internal sputum can be reduced, thereby increasing the accuracy of sputum sampling and detection. When collecting sputum, by arranging a guide rod at the lower end of the through hole and a hydrophobic layer on the inner wall, the hydrophobic layer can reduce the adhesion of sputum in the through hole. By utilizing the guide rod, the flow rate of sputum can be accelerated, thereby improving the collection speed of sputum.

[0013] 2. The utility model rotates the adjustment plate through the movable plate, O-ring and scraper arranged on the outside of the screw. The screw is used for transmission, so that the movable plate can be moved at a constant speed to adjust the position of sputum collection, which is convenient for staff to sample sputum. The scraper can be used to clean the sputum after sampling, which reduces the cleaning difficulty for staff. BRIEF DESCRIPTION OF THE DRAWINGS
