A drug addition port 35 is installed on the surface of the circulating hyperthermic perfusion device 9 below the intubation port 10. All components are connected by pipes. The saline inside the saline bag 34 is heated by the heating device 32. The heated saline enters the patient's abdominal cavity through the intubation port 10 for circulation. At the same time, chemotherapy drugs enter the pipeline through the drug addition port 35, realizing the hyperthermic perfusion circulation treatment of the patient's abdominal cavity.

[0037] The method of use in this embodiment is as follows: First, have the patient lie on the reclining board 5, and adjust the position of the two mounting blocks 701 according to the patient's legs so that the patient's legs are positioned between the two leg fixing plates 705. Then, rotate the adjusting handle 703 to drive the bidirectional screw 702 to rotate. The bidirectional screw 702 drives the two leg fixing plates 705 to move closer to each other through the two threaded blocks 704. The leg fixing plates 705 can clamp the patient's thighs and fix the patient's legs. Then, put the upper limb fixation strap 8 on the patient's shoulder, and use the adjusting block 25 to wrap the upper limb fixation strap 8 around the patient's shoulder. Pass the strap 23 through the connecting ring 24 on the upper limb fixation strap 8, and use the two straps 23 to pull the upper limb fixation strap 8. When performing drug infusion, connect the infusion pipe to the insertion port 10 on the circulating hot infusion device 9, and connect the pipe... The intubation tube is connected to the patient's body. The saline solution inside the saline bag 34 is heated by the heating device 32. The heated saline solution enters the patient's abdominal cavity through the intubation port 10 for circulation. At the same time, chemotherapy drugs enter the tube through the drug addition port 35, realizing the hot perfusion circulation treatment of the patient's abdominal cavity. The perfusion tube is held by the upper clamping plate 20 and the lower clamping plate 16. When the patient's position needs to be changed, the drive motor 603 drives the meshing gear 602 to rotate. The meshing gear 602 drives the semi-circular rack 601 to swing. The semi-circular rack 601 drives the reclining board 5 to swing around the support shaft 3, realizing the adjustment of the angle of the reclining board 5. The patient can be in a side-turned position without the need for medical staff to assist in turning the patient. After the hot perfusion circulation of drugs in the abdominal cavity is completed, the patient can get off the reclining board 5.
