The surface of the limiting column 710 is attached to the inner wall of the spring 709.

[0031] The hollow rubber block 5 is located directly above the through hole 706. The second air inlet pipe 702 and the liquid inlet pipe 703 are located directly below the through hole 706. The elastic force of the spring 709 is greater than the weight sum of the U-shaped plate 705 and the hollow block 708.

[0032] It should be noted that when the positioning column 701 and the U-shaped plate 705 are inserted into the positioning groove 606, the positioning column 701 is supported by the baffle 607, and the through hole 706 on the U-shaped plate 705 is aligned with the second air inlet pipe 702 and the liquid inlet pipe 703, at this time, the sputum can enter the sputum bag 8 through the sputum suction tube 10, the hose 4 and the liquid inlet pipe 703 in turn, and the air in the sputum bag 8 can enter the sputum suction device main body 1 through the second air inlet pipe 702 and the first air inlet pipe 3 in turn, and when the positioning column 701 and the U-shaped plate 705 are taken out from the positioning groove 606, the through hole 706 can be automatically misaligned with the second air inlet pipe 702 and the liquid inlet pipe 703 by the elastic force of the spring 709, and the second air inlet pipe 702 and the liquid inlet pipe 703 are sealed by the U-shaped plate 705.

[0033] As shown in Figures 1 to 8 The side close to the connecting block 604 of the positioning column 701 is fixedly connected with a U-shaped column 11, the inner wall of the U-shaped column 11 is abutly provided with a fool-proof block 12, and the bottom of the fool-proof block 12 is fixedly connected with the upper surface of the circular ring 605.

[0034] It should be noted that when the positioning column 701 is correctly inserted into the positioning groove 606, the inner wall of the U-shaped column 11 is in contact with the fool-proof block 12, and when the positioning column 701 is placed, the position between the U-shaped column 11 and the fool-proof block 12 can be observed to determine whether the positioning column 701 is placed correctly, so that the liquid inlet pipe 703 is aligned with the first air inlet pipe 3 due to the incorrect placement of the positioning column 701, and the sputum sucked is directly introduced into the sputum suction device main body 1 through the liquid inlet pipe 703 and the first air inlet pipe 3.

[0035] The working principle of the utility model is as follows: before sputum suction, the two circular rings 605 on the connecting block 604 are turned to the front and rear sides of the support frame 2 through the stepping motor 602, then the self-sealing cover 7 with the sputum bag 8 is inserted into the positioning groove 606, and the inner wall of the U-shaped column 11 is in contact with the fool-proof block 12, at this time, the self-sealing cover 7 is supported by the baffle 607 in the positioning groove 606, and the through hole 706 is aligned with the second air inlet pipe 702 and the liquid inlet pipe 703 through the cooperation of the positioning groove 606 and the U-shaped plate 705.

[0036] During sputum suction, one of the circular rings 605 is turned to the lower side of the support frame 2 through the stepping motor 602, and the through hole 706 is aligned with the hollow rubber block 5, at this time, the first air inlet pipe 3 is communicated with the second air inlet pipe 702 through the hollow rubber block 5, and the hose 4 is communicated with the liquid inlet pipe 703, then the sputum suction tube 10 is inserted into the respiratory tract of the patient, and the sputum suction device main body 1 is opened, at this time, the negative pressure is generated in the sputum bag 8 through the sputum suction device main body 1, and the sputum in the respiratory tract of the patient is sucked into the sputum bag 8 through the negative pressure.

[0037] When the sputum in the sputum bag 8 reaches the specified amount, the sputum suction device main body 1 is closed first, then the next sputum bag 8 is turned to the position under the support frame 2 through the stepping motor 602, and the sputum bag 8 containing sputum is turned to the left side of the support frame 2, at the same time, the second air inlet pipe 702 in the new sputum bag 8 is communicated with the first air inlet pipe 3 and the liquid inlet pipe 703 in the new sputum bag 8 is communicated with the hose 4 through the hollow rubber block 5, then the sputum suction is continued by opening the sputum suction device main body 1.

[0038] At the same time, the medical staff takes the sputum bag 8 containing sputum from the rotating mechanism 6, and inserts the self-sealing cover 7 with a new sputum bag 8 into the positioning groove 606, when the sputum bag 8 containing sputum is taken from the rotating mechanism 6, the through hole 706 is automatically staggered with the second air inlet pipe 702 and the liquid inlet pipe 703 through the elastic force of the spring 709, and the second air inlet pipe 702 and the liquid inlet pipe 703 are sealed through the U-shaped plate 705.

[0039] The above is only the preferred embodiment of the present application, it should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, can make a number of improvements and refinements, these improvements and refinements should also be considered as the protection scope of the present application. The structures, devices and operation methods not specifically described and explained in the present application, if no special description and limitation, are implemented according to the conventional means in the art.
