8. A method for operating a CT device with a ventilator, characterized in that: Its working method includes the following steps: A: When the bed (30) needs to carry a pet and move it into the CT scanner (10) for scanning and detection, the transmission mechanism (1022) inside the transmission seat (102) drives the ventilator (20) to move linearly on the transmission seat (102). When the ventilator (20) moves linearly on the transmission seat (102), it drives the pet carried by the bed (30) to move into the scanning hollow part (101) of the CT scanner (10) for scanning and detection; B: When the transmission mechanism (1022) drives the ventilator (20) to move linearly on the transmission seat (102), the first screw transmission assembly (103) and the second screw transmission assembly (104) are simultaneously started and operated to synchronously thread the movable plate (201) at the bottom of the ventilator (20) to move linearly on the transmission seat (102), and the movement slots (1021) on both sides of the transmission seat (102) are used to allow the movable plate (201) to move linearly on the transmission seat (102), so that when the ventilator (20) is driven to move, it drives the pet carried by the bed (30) to move into the scanning hollow part (101) of the CT scanner (10) to be scanned and detected; C: When the pet is being scanned by a CT scanner (10) and needs to use a ventilator (20) to control the breathing pressure and frequency, the bifurcated tube end (206) of the telescopic trachea (205) is inserted into the nose of the pet. When the ventilator (20) is running to provide gas to the pet, the turbine (2031) is running to allow the intake pipe (203) to draw in external gas. At this time, the first electronic valve (2032) on the intake pipe (203) is opened, and the second electronic valve (2041) on the exhaust pipe (204) is closed. Then, the gas drawn into the intake pipe (203) is transmitted to the pet through the telescopic trachea (205) for inhalation. When the ventilator (20) is running to discharge the exhaled waste gas of the pet, the exhaust pipe (2031) is closed. 4) is opened, and the first electronic valve (2032) and the turbine (2031) on the air intake pipe (203) are closed, then the waste gas exhaled by the pet can be transmitted to the exhaust pipe (204) through the retractable air pipe (205) for discharge; the ventilator (20) controls the opening of the air intake pipe (203) to provide the pet with inhalation pressure and frequency, and controls the opening of the exhaust pipe (204) to provide the pet with exhalation pressure and frequency according to the operation of the CT scanner (10), thereby realizing that the ventilator (20) cooperates with the operation of the CT scanner (10) to automatically assist in controlling the breathing pressure and frequency of the pet, so that the pet can successfully complete the scanning detection of the CT scanner (10).
