Further, the inner diameter of the filter cartridge is 1.5 to 2.5 times of the inner diameter of the vent hole of the end cap.

Furthermore, an oxygen pipe interface is arranged on the top surface of the end cap, and an oxygen pipe cap is arranged on the oxygen pipe interface.

Furthermore, a quincunx handle is arranged on the outer wall of the middle part of the sleeve.

Furthermore, a rhombic handle is arranged on the outer wall of the joint of the thick pipe and the thin pipe of the reducer union.

The using method of the utility model is as follows:

connecting the thin tube end of the reducer union to the outer end of the tracheotomy tube, and manually rotating the end cap to ensure that the sleeve vent hole completely corresponds to the end cap vent hole, so that the air passage is completely opened and the ventilation capacity is maximum; manually rotating the end cap to ensure that the sleeve vent holes and the end cap vent holes are staggered and correspond to each other, and completely closing the air passage; the end cap is rotated manually, so that the sleeve vent hole and the end cap vent hole are staggered and correspond to each other, the opening degree of an air passage can be adjusted, the ventilation volume is adjusted, and the intubation tube is conveniently closed step by step. When oxygen inhalation is needed, the oxygen tube cap is taken off, and the oxygen tube interface is connected with the oxygen tube.

Compared with the prior art, the utility model has the beneficial effects that:

the utility model sets a filter cartridge connected to the cylinder wall at the position of each end cap vent hole, and installs a filter element in the filter part. The filter element replaces the filtering function of the oral cavity and the nasal cavity, and the air inhaled into the lungs by a patient is filtered, so that dust and harmful bacteria in the air can be effectively prevented from being inhaled into the lungs. The utility model has simple and reasonable structure, easy processing and manufacture and convenient use and replacement of the filter element.
