Rapid exhaust balloon catheter

The utility model relates to the technical field of interventional medical instruments, and provides a quick exhaust balloon catheter which comprises a catheter connector, a catheter body and a balloon, the catheter connector is connected with the catheter body, and the balloon is fixed at the front end of the catheter body through a developing ring. An inner core channel and a liquid injection channel which are communicated with the catheter body are formed in the catheter connector, a sealing connector is arranged at the end of the catheter connector, a sealing inner core penetrating through the inner core channel and the catheter body is connected to the sealing connector, and a catheter sealing piece is arranged at the end of the sealing inner core. A straight-through type exhaust structure that the sealing inner core penetrates through the single-cavity catheter is adopted, gas in the balloon catheter can be directly exhausted from an opening in the front end of the catheter, the exhaust process is simpl
