Features:

■ Technologically advanced injection of fluid and gas into the pleural cavity is improved from manual operation to electric power, thus realizing the automation of fluid and gas injection.

■ Made of imported polymer material, vivid image.

■ The liquid level of the drainage bottle and the water column in the water seal tube can fluctuate up and down with the rhythm of respiratory movement. The rise of the abdominal wall simulates the rise of inspiratory water column, and the fall of the abdominal wall simulates the fall of expiratory water column.

■ Adjustable fluctuation amplitude of the water seal tube: It is of great clinical importance to observe the fluctuation amplitude of the water column. The fluctuation amplitude of the water seal tube of this product can be adjusted by the knob on the model, which can be adjusted to (1) no fluctuation (2) fluctuation amplitude is more than normal (4-6cm) (3) fluctuation amplitude is less than normal.

■ If the puncture site is wrong, there will be automatic voice prompts.

■ When the puncture is correct, there is a more obvious sense of falling, the effect is realistic.
