Medical pulsation vacuum sterilization device

The invention relates to the technical field of pulsating vacuum sterilization devices and discloses a medical pulsating vacuum sterilization device which comprises a box body, the front face of the box body is rotationally connected with a box door, the back face of the box body is fixedly connected with an air inlet pipe, the air inlet pipe penetrates through the outer wall of the box body and extends into the box body, and the back face of the box body communicates with an air outlet pipe. The back of the box is fixedly connected with a motor, and the output end of the motor is fixedly connected with a rotating shaft. As the rotating disc rotates, a sliding rod connected to the surface of the rotating disc is driven to rotate, the sliding rod drives a sliding block to slide on the surface of a circular ring, the contact face of a fixed ring block and a push rod is in an arc shape, and as the sliding block drives the push rod to move, the fixed ring block pushes the push rod to move towards the inner wall o
