Energy-saving and environment-friendly medical instrument circulating perfusion, washing and disinfection device and method

The invention discloses an energy-saving and environment-friendly medical instrument circulating perfusion, washing and disinfection device, and belongs to the field of medical instrument cleaning. According to the energy-saving and environment-friendly medical instrument circulating perfusion, washing and disinfection device, a motor drives a rotating block to rotate, and the rotating block drives a sleeve to do eccentric motion through a connecting plate, so that the sleeve drives a rotating rod to rotate in a cleaning barrel along the inner wall of the cleaning barrel, and thus a spraying head is driven to rotate on the inner wall of the cleaning barrel to clean medical instruments; meanwhile, a motor drives a driven rod to rotate through a first synchronous belt, the driven rod drives a second gear to rotate to be meshed with a first gear, the first gear drives a rotating rod to rotate in a sleeve, and therefore the spraying head rotates along the inner wall of the cleaning barrel and rotates at the same
