Abstract

The utility model discloses sputum suction equipment for breathing, which relates to the technical field of pneumology department and comprises a device bottom plate, the top of the device bottom plate is fixedly connected with an annular fixing component, a sputum suction container is inserted into the annular fixing component, a protective cover is inserted into the top of the sputum suction container, and a sealing ring is inserted into the protective cover. Through the arrangement of the sealing ring and the filtering and purifying assembly, the safe and filtering effects are achieved when a person operates the device, the filtering and purifying assembly conducts multi-layer filtering, the first layer of polypropylene film rapidly captures large-particle impurities in sputum through the large aperture of the first layer of polypropylene film, and the subsequent two layers of cellulose filter cotton conduct deep purification in a relay mode; the sealing ring is made of high-elasticity and aging-resistant medical silica gel, so that the risk of leakage can be effectively blocked, and the safety is improved.
