[0064] Working principle: During use, the buffer sits on the basin body 4, and the medicine liquid is placed in the medicine box 6 after being properly heated, and the motor 20 is started to rotate the shaft 21, and the stirring rod 23 is driven to rotate through the action of the bevel gear set 22. When the stirring rod 23 rotates, the stirring blade 24 is driven to rotate synchronously, thereby stirring and mixing the medicine liquid to improve the uniformity of the medicine liquid;

[0065] The stirring rod 23 rotates while driving the reciprocating screw rod 7 to rotate, so that the moving plate 8 reciprocates. When the moving plate 8 reciprocates, it drives the connecting block 39 to move synchronously, so that the connecting block 39 drives the first slide bar 26 and the infusion piston 27 to reciprocate in the effect of being engaged with the connecting ring 40, so that the slider 41 moves synchronously with the connecting block 39 along the length direction of the slide groove 42;

[0066] During the reciprocating movement of the infusion piston 27, the liquid medicine is extracted through the liquid extraction tube 29 and alternately enters the infusion tube 25 through the two liquid inlet tubes 28, and then alternately discharged through the two liquid outlet tubes 30 into the infusion tube 31, and finally sprayed onto the perianal postoperative wound surface through the atomizing nozzle 11, thereby achieving the effect of preventing pollution;

[0067] When the movable plate 8 moves back and forth, it drives the second sliding rod 33 and the gas delivery piston 34 to move back and forth, so that external gas is extracted through the suction pipe 36. During the process of the gas passing through the air inlet channel 12, the gas is filtered and purified by the filter screen 46 and then heated by the electric heating screen 13. Then, the gas flows through the suction pipe 36 and alternately passes through the two air inlet pipes 35 to enter the air delivery cylinder 32. Then, it is alternately discharged through the two air outlet pipes 37 and enters the air distribution cylinder 14 through the air delivery pipe 38. At this time, it is transported through the first air distribution pipe 15 and sprayed into the medicine box 6 by the air outlet nozzle 16, so as to achieve heating of the liquid medicine and ensure that the patient's comfort is improved when the wound surface of the patient's perianal surgery is continuously flushed.

[0068] After flushing the perianal surgery wound of the patient, the movable plate 8 can be placed at the highest position, and the electric telescopic rod 45 is started to move the connecting plate 10 to the right, so that the connecting plate 10 drives the slider 41 and the connecting block 39 to move to the right, so that the connecting block 39 is separated from the connecting ring 40, and at the same time, the adjusting rod 43 drives the adjusting piston 44 to move to the right along with the connecting plate 10, so that the adjusting piston 44 moves to the right side of the air supply pipe 38. At this time, the reciprocating movement of the movable plate 8 will not drive the first sliding rod 26 to move, and the transported hot air will enter the through pipe 18 through the second air distribution pipe 17 and be discharged through the nozzle 19, so as to achieve drying of the perianal surgery wound of the patient and improve the anti-pollution efficiency of the perianal surgery wound of the patient;

[0069] After drying, the movable plate 8 is moved to the highest position, and the connecting plate 10 is reset to the left by the electric telescopic rod 45, so that the connecting block 39 is moved to the left, so that the connecting ring 40 is placed in the notch of the connecting block 39, to ensure that the movable plate 8 can drive the first slide bar 26 to move again when it moves, and at the same time, the adjusting rod 43 and the adjusting piston 44 are reset to the left for subsequent use.
