[0023] As Figure 1 shown in the figure, as a further solution of this embodiment, the dry rotary vane vacuum pump mechanism includes: vacuum tube 30 of No. 11, manual valve 707 of No. 7, gas check valve 1501 of No. 1, electric valve 804 of No. 4, vacuum tube 31 of No. 12, manual valve 709 of No. 9, dry rotary vane vacuum pump 101 of No. 1, vacuum tube 29 of No. 10, manual valve 708 of No. 8, gas check valve 1502 of No. 2, electric valve 805 of No. 5, vacuum tube 32 of No. 13, manual valve 710 of No. 10, dry rotary vane vacuum pump 102 of No. 2, vacuum tube 33 of No. 14; one end of vacuum tube 30 of No. 11 is connected to vacuum tube 30 of No. 11 at the other end relative to the bacterial filter mechanism, and the other end is connected to dry rotary vane vacuum pump 101 of No. 1; on vacuum tube 30 of No. 11 in the direction from vacuum tube 28 of No. 9 to dry rotary vane vacuum pump 101 of No. 1, there are successively arranged manual valve 707 of No. 7, gas check valve 1501 of No. 1, and electric valve 804 of No. 4; one end of vacuum tube 31 of No. 12 is connected to dry rotary vane vacuum pump 101 of No. 1, and the other end is connected to vacuum tube 33 of No. 14; one end of vacuum tube 29 of No. 10 is connected to vacuum tube 30 of No. 11 at the other end relative to the bacterial filter mechanism, and the other end is connected to dry rotary vane vacuum pump 102 of No. 2; on vacuum tube 29 of No. 10 in the direction from vacuum tube 28 of No. 9 to dry rotary vane vacuum pump 102 of No. 2, there are successively arranged manual valve 708 of No. 8, gas check valve 1502 of No. 2, and electric valve 805 of No. 5; one end of vacuum tube 32 of No. 13 is connected to dry rotary vane vacuum pump 102 of No. 2, and the other end is connected to vacuum tube 33 of No. 14.

[0024] As Figure 1As shown in the figure, as a further solution of this embodiment, the disinfection water tank 4 is connected to the 17th vacuum tube 36; a 19th vacuum tube 38 is connected to one side of the disinfection water tank 4; a chlorine adding machine 14 is connected to the 19th vacuum tube 38 at the other end relative to the disinfection water tank 4; an electric stirrer 12 is provided on the disinfection water tank 4; an 18th vacuum tube 37 is connected to one end of the disinfection water tank 4; a 3rd electric valve 803 is provided on the 18th vacuum tube 37.

[0025] As Figure 1 shown in the figure, as a further solution of this embodiment, a 1st manual valve 701 is provided on the 4th vacuum tube 23.

[0026] The 1st dry rotary vane vacuum pump 101 and the 2nd dry rotary vane vacuum pump 102 operate in a "one in use and one standby" mode. Under normal circumstances, only one is operating, and they rotate according to the set time. At the same time, when one of them fails, the other can be automatically put into use.

[0027] When the 1st dry rotary vane vacuum pump 101 starts, the PLC control box 2 controls the 4th electric valve 804 to open and the 5th electric valve 805 to be in the closed state; similarly, when the 2nd dry rotary vane vacuum pump 102 starts, the PLC control box 2 controls the 5th electric valve 805 to open and the 4th electric valve 804 to be in the closed state.

[0028] The 1st bacterial filter 301 and the 2nd bacterial filter 302 should work simultaneously, and the processing capacity of each one is not less than the rated exhaust volume of the 1st dry rotary vane vacuum pump 101 or the 2nd dry rotary vane vacuum pump 102 to ensure the biological safety of the system exhaust. The matching filter element precision of the 1st bacterial filter 301 or the 2nd bacterial filter 302 is between 0.01um and 0.2um and the bacterial filtration efficiency ≥ 99.995%. When the measured pressure difference value of the 1st pressure difference sensor 1901 supporting the 1st bacterial filter 301 ≥ the set pressure difference value, or when the measured pressure difference value of the 2nd pressure difference sensor 1902 supporting the 2nd bacterial filter 302 ≥ the set pressure difference value, the PLC control box 2 will give an on-site sound and light alarm to prompt the management staff to replace the filter element. At the same time, the PLC control box 2 can display the alarm information on the operating room alarm display screen 17 to prompt the hospital in the operating room to pay attention to the filter element overpressure situation and avoid medical accidents.

[0029] When the No. 1 dry rotary vane vacuum pump 101 or the No. 2 dry rotary vane vacuum pump 102 is in normal operation, the PLC control box 2 monitors the value of the remote pressure gauge 18 in real time. The value of the remote pressure gauge 18 can feedback the internal vacuum degree P of the medical vacuum tank 11. When the internal vacuum degree P of the medical vacuum tank 11 is not less than the set upper limit of the vacuum degree P upper limit, that is, P≥P upper limit, the PLC control box 2 will control the No. 1 dry rotary vane vacuum pump 101 or the No. 2 dry rotary vane vacuum pump 102 in operation to stop. In this state, no vacuum pump is running, and the vacuum suction operation in the operating room is carried out by relying on the internal stored vacuum degree of the medical vacuum tank 11; when the internal vacuum degree P of the medical vacuum tank 11 is not greater than the set lower limit of the vacuum degree P lower limit, that is, P≤P lower limit, the PLC control box 2 will control the No. 1 dry rotary vane vacuum pump 101 or the No. 2 dry rotary vane vacuum pump 102 in operation to start, continuously providing vacuum degree for the system until the internal vacuum degree P of the medical vacuum tank 11 is higher than the set upper limit of the vacuum degree P upper limit and then stops, repeating the above actions. P upper limit and P lower limit can be set on site at the PLC control box 2 according to different scenario requirements.

[0030] The dirt storage liquid tank 10 stores liquid dirt such as patient sputum, blood, pus water and other tissue fluids generated during the operation in the operating room. The PLC control box 2 can monitor the actual measured liquid level L of the liquid dirt in the dirt storage liquid tank 10 in real time through the No. 2 liquid level sensor 902. When the actual measured liquid level L is not less than the set upper limit of the liquid level L upper limit, that is, L≥L upper limit, the PLC control box 2 will control the No. 1 electric valve 801 to open and discharge the liquid dirt in the dirt storage liquid tank 10 to the disinfection water tank 4; when the actual measured liquid level L is not greater than the set lower limit of the liquid level L lower limit, that is, L≤L lower limit, the PLC control box 2 will control the No. 1 electric valve 801 to close to prevent air circulation between the dirt storage liquid tank 10 and the disinfection water tank 4. L upper limit and L lower limit can be set on site at the PLC control box 2 according to different scenario requirements.

[0031] The PLC control box 2 monitors the liquid level of the disinfection water tank 4 in real time through the No. 1 liquid level sensor 901. When the actual measured liquid level L1 is not less than the set disinfection liquid level L disinfection, that is, L1≥L disinfection, the PLC control box 2 will control the chlorine adding machine 14 to start and inject chlorine-containing disinfectant into the disinfection water tank 4 until the chlorine concentration of the liquid dirt in the disinfection water tank 4 meets the sterilization dose, and then the PLC control box 2 controls the chlorine adding machine 14 to stop running.

[0032] Note: The PLC control box 2 can automatically calculate the running time of the chlorine adding machine 14 according to the disinfection liquid level L disinfection of the disinfection water tank 4, the concentration of the injected chlorine-containing disinfectant and the disinfectant injection rate of the chlorine adding machine 14 according to the sterilization dose requirements.

[0033] At the same time, the PLC control box 2 controls the electric stirrer 12 to start for forced stirring to increase the contact area between the chlorine-containing disinfectant and the liquid dirt in the disinfection water tank 4. The stirring time can be set on site at the PLC control box 2 according to different scenario requirements.

[0034] Meanwhile, when the chlorine-containing disinfectant meets the set contact time T with the liquid dirt, the PLC control box 2 will control the 3rd electric valve 803 to open. The disinfected liquid dirt enters the hospital sewage treatment facility through the 18th vacuum tube 37 for harmless treatment. Under normal operating conditions, the 3rd electric valve 803 is in a normally closed state. The set contact time T can be set on-site at the PLC control box 2 according to different scenario requirements.
