The upper ends of multiple fixed rods 23 are all fixedly connected to the bottom surface of the shielding plate 24. The shielding plate 24 is arranged above the pipe opening at the upper end of the fixed tube 22 and is a conical plate. The fixed tube 22 is connected to the shielding plate 24 by setting the fixed rod 23, so that the shielding plate 24 is used to shield the upper part of the pipe opening of the fixed tube 22. When the sucked body fluid flows down from the top of the storage tube 7, the shielding plate 24 can be used to shield the body fluid to prevent the body fluid from entering the fixed tube 22 and causing contamination to the fixed tube 22, the fixed tube 1 20 and the negative pressure machine 16.

[0040] The bottom end of the second fixing tube 22 is plugged into the left end of the first fixing tube 20. The first fixing tube 20 is fixedly arranged at the bottom of the placement groove 14 and is sleeved in the second mounting groove 18 and the first mounting groove 17. The second mounting groove 18 is opened at the bottom end of the left side of the box body 1, and the first mounting groove 17 is opened on the right side of the box body 1.

[0041] The right end of the fixed pipe 20 is fixedly connected to the air inlet pipe of the negative pressure machine 16, and the bottom end of the negative pressure machine 16 is fixedly connected to the bottom of the mounting groove 17. A plurality of ventilation grooves 15 are correspondingly opened on the right side of the exhaust port of the negative pressure machine 16. The plurality of ventilation grooves 15 are all opened on the left side of the groove 2, and the groove 2 is opened on the bottom of the right side of the box body 1;

[0043] The operating steps of the present invention are:

[0044] When using the device to suck the body fluid of the patient's surgical incision, the user can insert the left end of the suction head 10 into the incision, and then control the negative pressure machine 16 to work through the control panel 4. When the negative pressure machine 16 works, the air in the storage cylinder 7 is sucked out through the fixed tube 1 20 and the fixed tube 2 22 to generate negative pressure in the storage cylinder 7. After the negative pressure is generated in the storage cylinder 7, the body fluid is sucked into the storage cylinder 7 through the fixed tube 3 25, the connecting hose 9, and the suction head 10. During the suction process, the user can observe the suction pressure through the barometer 11 to adjust the negative pressure machine 16.

[0045] During the suction process, the user can rotate the nut 21 to make the nut 21 detach from the guide plate 26, and then pull the sliding plate 30 to slide to the left along the slide groove 38 to make the separation plate 27 extend from the rotating chamber 33. When the separation plate 27 extends to a suitable length, the user stops pulling the sliding plate 30, and rotates the nut 21 in the opposite direction to make the nut 21 contact with the guide plate 26 again to limit the sliding plate 30. At this time, the user can peel off the blood vessels and nerves at the left end of the suction head 10 through the separation plate 27, and the user turns the fixing ring 29 to make the separation plate 27 rotate in the rotating chamber 33 to adjust the position of the separation plate 27.

[0046] After completing the suction, the user can remove the suction head 10 from the incision and turn off the negative pressure machine 16. Then the user can open the valve 12 to allow the outside air to enter the storage cylinder 7 through the pressure regulating tube 13 to balance the pressure inside the storage cylinder 7. Then the user can separate the connecting hose 9 from the fixed tube three 25 to disassemble the connecting hose 9 and the suction head 10, and insert the hand into the pick-up and release groove 5 to hold the storage cylinder 7 and pull the storage cylinder 7 upwards, so that the fixed tube two 22 is separated from the fixed tube one 20. Then the user can clean the body fluid in the storage cylinder 7.
