The invention relates to a pediatric
sputum suction device, and solves the problem that currently the
sputum suction mode cannot be adjusted in time according to different patient conditions during
sputum suction. The pediatric sputum suction device includes a mobile body, which is equipped with a negative pressure suction unit, an
oxygen humidifying unit and a back slap unit. The back slap unit can act from front to back sequentially for back slapping, and includes
piston rods, the
piston rods are equipped with
piston cylinders cooperatively, the piston cylinders are connected to gas storageequipment, the gas storage equipment is communicated with a three-way
pipe, one port of the three-way
pipe is communicated with a negative pressure
bottle, another port of the three-way
pipe is communicated with a humidifying tank, the negative pressure
bottle is communicated with a liquid collecting
bottle, the liquid collecting bottle is communicated with a sputum suction tube, the sputum suction tube is communicated with a humidifying tube, and the humidifying tube and the sputum suction tube form an integral two-channel pipe, the mobile body is provided with an adjustable support plate, which is located on the right side of the back slap unit, and the support plate is equipped with a position fixation unit. The pediatric sputum suction device provided by the invention can control the
oxygen humidifying unit, the negative pressure suction unit and the back slap unit to adapt to the sputum suction
modes of different patients according to the different conditions of patients.
