The invention relates to a thrombus aspiration system and a control method of the thrombus aspiration system, relates to the technical field of medical equipment, and can improve the thrombus aspiration efficiency. An intelligent control module in the system is configured to execute the steps of determining the pressure difference between the near end and the far end according to pressure data collected by a first pressure sensor and pressure data collected by a second pressure sensor, determining the pressure difference change rate of the pressure difference, and determining the pressure difference change rate of the pressure difference according to flow data collected by a flow sensor. Determining the flow change rate of the blood flow in the suction catheter; according to the pressure difference change rate and the flow change rate, the medium type corresponding to the current suction medium of the suction guide pipe is determined; when the suction medium is blood, intermittent suction is performed on the blood according to a preset frequency when a valve in the air pressure state conversion module is in a closed state; and when the suction medium comprises thrombus of a target volume, determining a target frequency corresponding to the target volume, and opening and closing a valve in the air pressure state conversion module for multiple times according to the target frequency while keeping suction.

This utility model relates to the field of laser processing equipment, and more particularly to a three-dimensional laser metal cutting machine, including a machine tool and air pipes. The machine tool is equipped with a gantry that moves back and forth. A laser cutter that moves left and right is mounted on the front side of the gantry. An air inlet hood is connected to the front side of the gantry, and a dust collector is mounted on the top of the gantry. One end of the air pipe is connected to the dust collector, and the other end is connected to the air inlet hood. A dual-axis motor is mounted in the middle of the air inlet hood, with drive shafts connected to both ends. A guide fan is mounted on the drive shaft, and the air outlet direction of the guide fan is aligned with the air pipe port. The gantry is equipped with protective components to block cutting debris. Through the linkage of a baffle and a stepper motor, the baffle swings vertically downward to form a semi-enclosed space, forcibly guiding the dust-laden exhaust gas into the air inlet hood. Combined with the controllable gap at the bottom of the baffle to draw in external cold air, this achieves efficient capture of exhaust gas and real-time cooling of the cutting area, curbing the spread of pollutants at the source.
