When the accumulated fluid leaks from the wound, the accumulated fluid will be blocked by the sealing cover 28 and absorbed by the absorbent cotton 29 to prevent the accumulated fluid from flowing out of the conical cover 23. When the accumulated fluid is too much to be completely absorbed by the absorbent cotton 29, the accumulated fluid will flow into the conical cover 23 through the guide groove 22 and be discharged from the conical cover 23 through the suction port 24 to prevent the accumulated fluid from accumulating, thereby preventing the accumulated fluid from leaking during the diversion process of the drainage tube 1, and avoiding the leakage of the liquid to pollute the medical environment.

[0056] The working principle and use process of the present invention:

[0057] First, use the second handle 315 to move the device and remove the patient. Then, set the connecting ring 21 at the extraction site and use the elastic fixing belts 211 on both sides to tie the connecting ring 21 to the patient, so as to facilitate the extraction of fluid from the patient and prevent the connecting ring 21 from moving at will during the extraction process. Make the sealing cover 28 close to the patient's skin and make the drainage needle 27 probe into the patient's wound. Then, start the negative pressure pump 34 to start extracting the accumulated fluid, so that the accumulated fluid in the wound is extracted through the drainage needle 27 and discharged from the conical cover 23 through the suction port 24 into the drainage tube 1, so that the accumulated fluid is transmitted to the liquid storage tank 31 through the drainage tube 1. When the accumulated fluid leaks from the wound, the accumulated fluid will be blocked by the sealing cover 28 and absorbed by the absorbent cotton 29 to prevent the accumulated fluid from flowing out of the conical cover 23.

[0058] When there is too much accumulated fluid to be completely absorbed by the absorbent cotton 29, the accumulated fluid will flow into the conical cover 23 through the guide groove 22, and be discharged from the conical cover 23 into the drainage tube 1 through the suction port 24, preventing the accumulation of accumulated fluid, thereby preventing the accumulated fluid from leaking during the diversion process of the drainage tube 1, and avoiding the leakage of liquid to pollute the medical environment.

[0059] After the liquid is extracted, the staff can use the first handle 310 to lift the liquid storage tank 31 and remove the first protective plate 312 and the second protective plate 314. Then, the tank cover 32 can be removed and the accumulated liquid in the liquid storage tank 31 can be cleaned, thereby extracting the accumulated liquid and preventing leakage of the accumulated liquid.
