2. The Infusion Port Standardized Automated Flush device of claim 1, wherein, The top surface of the housing is provided with a glass window, and below the glass window are a pulse adjustment knob, a pressure adjustment knob, and a switch.

3. The Infusion Port Standardized Automated Flush device of claim 1, wherein, The length of the support tube is less than the length of the shell. One end of the support tube is connected to one of the connectors, and the other end is a free end, corresponding to the other connector. The two connectors are respectively connected to the liquid storage bottle and the flushing needle.

4. The Infusion Port Standardized Automated Flush device of claim 3, wherein, The flushing hose passes through the support pipe and is connected to two connectors at both ends.

5. The Infusion Port Standardized Automated Flush device of claim 4, wherein, The pulse adjustment assembly includes a U-shaped guide bracket located at the bottom of the housing. A through hole is provided in the middle of the guide bracket. A cylindrical moving block is movably connected inside the guide bracket. The bottom of the moving block is connected to a pressing block via a connecting rod. The pressing block is located outside the guide bracket. The connecting rod passes through the through hole and connects to the pressing block.

6. The Infusion Port Standardized Automated Flush device of claim 5, wherein, The connecting rod is also fitted with a spring. One end of the spring abuts against the bottom of the moving block, and the other end abuts against the inner wall of the middle through hole of the guide bracket. The outer diameter of the spring is larger than the diameter of the through hole and smaller than the diameter of the moving block. The moving block has a compression position and a free position. When the moving block is in the compression position, the spring is compressed. When the moving block is in the free position, the spring returns to its original position.

7. The Infusion Port Standardized Automatic Flush device of claim 6, wherein, The housing is also equipped with a cam that cooperates with the moving block. The bottom of the cam is connected to the output shaft of the servo motor mounted on the housing, and the outer end face of the moving block abuts against the edge of the cam.

8. The Infusion Port Standardized Automatic Flush device of claim 1, wherein, The pressure regulating assembly includes a slide rail located at the bottom of the housing. The length direction of the slide rail is perpendicular to the length direction of the flushing hose. Both ends of the slide rail are connected to the bottom of two columns, which are vertically fixed to the bottom of the housing. One of the two columns is equipped with a servo motor, and the other is equipped with a bearing seat.

9. The Infusion Port Standardized Automated Flush device of claim 8, wherein, Two sliders are spaced apart on the slide rail, and a squeezing plate is installed above each slider. The two squeezing plates are located on both sides of the flushing hose. The top of the two squeezing plates is connected to two columns through a bidirectional threaded rod. The top of the squeezing plates is connected to the bidirectional threaded rod through a convex ring. One end of the bidirectional threaded rod is connected to the second servo motor, and the other end is connected to the bearing seat.

10. The Infusion Port Standardized Automatic Flush device of claim 9, wherein, The convex ring has an internal thread that mates with the external thread of the bidirectional threaded rod. The two convex rings are located at the two ends of the bidirectional threaded rod, and the internal threads in the two convex rings are in opposite directions.
