[0003] In the prior art, the conventional cleaning device for anesthesia equipment generally places the catheter in the cleaning liquid for cleaning. Since the catheter pipe is generally long, sputum and other dirt adhere to the upper inner wall of the catheter. By immersing the catheter in the cleaning liquid, it may not be possible to effectively clean the sputum and other dirt, which will affect the cleaning efficiency. At the same time, the utility model patent with announcement number CN211757364U discloses a cleaning device for anesthesia equipment, including a filter box, a cleaning box is arranged at the upper end of the filter box, a first cleaning box and a second cleaning box are arranged inside the cleaning box, and a plurality of hollow brush rollers and filter drawers are arranged inside the first cleaning box and the second cleaning box, a motor box is arranged at the upper end of the cleaning box, a power mechanism is arranged inside the motor box, and a plurality of water spray mechanisms are arranged at the rear end of the cleaning box. The volume of the overall device of this utility model is relatively large, and its cleaning device generally places the catheter in the cleaning liquid for cleaning. By immersing the catheter in the cleaning liquid, it may not be possible to effectively clean the sputum and other dirt, which will affect the cleaning efficiency. Utility Model Content

[0032] This embodiment starts the cylinder to make the cylindrical block move back and forth inside the cylinder. The cylindrical block moves to the right inside the cylinder and squeezes the reset spring. When the cylindrical block moves back and forth, the reset spring releases elastic potential energy to push the cylindrical block back to its original position, thereby driving the cylindrical block to rotate, so that the long rod drives the cleaning brush to rotate to perform deep cleaning of the inside of the catheter. By rotating the cleaning brush back and forth inside the catheter for cleaning, sputum and other dirt are prevented from adhering to the inner wall of the catheter, thereby improving the cleaning efficiency.
