Then when the bladder 310 needs to be inflated/liquid, the piston rod 332 is rotated to make the clamping plate and the stopper 3313 detached, and the piston rod 332 moves towards the injection interface 3311 under the action of the retraction elastic force of the spring 333, Thereby, the gas or liquid in the syringe 331 is compressed, so that the gas or liquid is pressed into the bladder 310, and the automatic inflation/liquid state is completed when the retracted elastic force of the spring 333 is balanced with the gas or liquid pressure in the bladder 310. . Preferably, a mark can be set on the piston rod 332 to indicate that the balloon body 310 is in a normal bulging state. When the position of the piston rod 332 changes, it means that the state of the balloon located at the tip of the bronchoscope has changed, so that the user can According to the specific position of the piston rod 332 located outside the body to determine and monitor whether the balloon located inside the body is in a normal blocking state, using this device to determine the method is simple and quick, and avoids repeated removal and placement of the balloon to the patient's wound and internal mucosa. s damage.
