(1)Install the sputum suction tube and sputum discharge tube (the sputum suction tube connector is in the center of the pumping tube, and the sputum discharge tube connector is on one side, don't reverse it).
(2)Make a suction test first to check whether the sputum aspirator leaks water and air, and whether there is any anti-gas when discharging, if there is anti-gas in the sputum tube, it can not be used.
(3)After proving good performance, one person holds the sputum aspirator and pulls the handle repeatedly, another person can use the sputum aspirator to suction sputum, and the skilled person can also be operated by one person. After the sputum is sucked out, water should be sucked at any time to flush out the accumulated sputum in the sputum storage room.
(4) When suctioning sputum in the room, the sputum tube should be placed inside the bottle to prevent sputum from being paralyzed.
(5)It is necessary to pay attention to not pulling too fast and too hard to prevent the negative pressure from damaging the mucous membrane tissues of the oral and nasal cavities.
(6)After use, it should be sucked and washed with water, and the sputum tube should be sterilized routinely, and the sputum aspirator and sputum tube should be sterilized with disinfectant to be ready for reuse. The sputum aspirator is an indispensable tool for preventing and treating patients' respiratory obstruction and rescuing asphyxiation. There are still many difficulties in the rescue of emergency asphyxia, especially in the conditions of war rescue, the problems encountered are more, neither is it possible to have skilled medical personnel at all levels of medical units for rescue, nor is it possible to have perfect medical equipment and adequate power supply. A few years ago, there was a foot-operated sputum aspirator without power supply on the market, but its structure was complicated, its attractiveness was far from meeting the needs, and its weight was several kilograms, which made it inconvenient to carry and use, and it was eliminated long ago. The sputum aspirator on the market is still mainly electric.
