Pulmonary alveolar lavage fluid collector

The utility model provides a pulmonary alveolar lavage fluid collector which comprises a collecting cylinder, a plugging cover is movably clamped on the inner side of the upper end of the collecting cylinder, the plugging cover comprises a sealing plug and an auxiliary plug, and the auxiliary plug comprises a guide ring, a limiting cylinder, a filter hole and a liquid guide inclined plate. After the sealing plug is plugged on the collecting cylinder, the liquid inlet pipe and the exhaust pipe are inserted into the inner side of the inserting groove, so that the auxiliary plugs which are symmetrically arranged are located at the ports of the liquid inlet pipe and the exhaust pipe respectively, when pulmonary alveolar lavage fluid is guided into the inner side of the collecting cylinder through the liquid inlet pipe, bubbles in the lavage fluid are scattered through the filtering holes in the auxiliary plugs, and then the bubbles in the lavage fluid are scattered. The lavage fluid drops to the inner side of the
