The invention discloses a flushing device, belongs to the technical field of
medical instruments, and particularly relates to an intelligent flushing and sucking variable-
diameter sputum suction tube device which comprises an outer
sputum suction tube and a flushing tube, the outer
sputum suction tube is designed to be in a conical shape with a
small head end and a large rear end so as to adapt to respiratory tracts of different parts, and the front end of the flushing tube is slightly shorter than the outer sputum suction tube. The sputum
aspirator is arranged in the sputum suction tube and connected with the sputum suction outer tube through the plug, the plug is provided with a plurality of plug spray holes, and the spray holes correspond to the spray holes in the sputum suction outer tube one to one, so that accurate flushing and suction are achieved. By means of the variable-
diameter design and the all-directional suction function, the device can adapt to respiratory tracts of different parts,
mucus of the end
bronchial tube is effectively removed, meanwhile, due to the multiple working
modes and the lumen separation design, operation flexibility and efficiency are improved, discomfort to a patient is reduced, and the device is simple in structure, safe, stable, reliable and suitable for popularization and application. According to the invention, the characteristics of all-around, rapid and tip directional flushing of the flushing tube and the suction tube are realized.
