Advantage of the present utility model：
Internal resistance self-changing described in the utility model, high ventilation double lumen endobronchial tube, by original fixed pipe partition
Structure cancellation is instead movable, self-limited type pipe interval, with this on the premise of pipe thickness is not changed, each to manage
The own internal diameter initial condition in chamber is not changed, but when carrying out ventilating in air flue, if wherein there is disease in certain side air flue
Become, cause the side airway pressure to increase, the situation that ventilation declines, self-changing's pipe interval catheter channels interval just can be along pressure
Power gradient, enters line displacement to lower resistance side, and so as to increase blocking side lumen diameter, and the amplitude of accommodation at variable pipe interval is
Being limited within controlled range, so as to both ensure that Ipsilateral ventilation, protecting offside air flue to have certain space again.Both most
The guarantee patient safety of limits, meets the feature of the air flue change of different patients again.
