[0023] When needing to wash and disinfect negative pressure sputum suction collection bottle 22, can first pull out the air hose two 33 of air connection pipe 242 top, then pull out the fixed disposable sputum suction hose, directly take down negative pressure sputum suction collection bottle 22 from places ring 21, again pull out sealed top cover 24 using pull handle 27, and rotate taper butt joint 281, can use the threaded connection of outer thread pipe 282 and threaded hole 241, remove whole taper butt joint 281, so that can more thoroughly wash and disinfect disposable sputum suction hose connecting taper butt joint 281, when installing, only need to rotate outer thread pipe 282 again to align threaded hole 241 and tighten, until limit disc 283 stops by the top of sealed top cover 24, can complete installation, and use threaded connection to improve sealing, again press whole sealed top cover 24 into the cavity of negative pressure sputum suction collection bottle 22 using pull handle 27, so that sealing plug 25 improves the sealing after clamping using the extrusion between the two rubber sealing rings 26 of its outer wall and negative pressure sputum suction collection bottle 22, again, soft air hose two 33 is reconnected with air connection pipe 242, and can carry out negative pressure sputum suction work again.

[0024] As Figure 4As shown, the sputum suction tube fixing mechanism 284 comprises a vertical plate 2841 fixedly installed on the top right side of the limiting disc 283, the top of the vertical plate 2841 is fixedly installed with a limiting box 2842, the left side of the limiting box 2842 is provided with a sliding groove 2843, the inner wall of the sliding groove 2843 is fixedly installed with a sliding rod 2844 between the front and back sides, the outer wall of the sliding rod 2844 is slidingly installed with a sliding block 2845 on the front and back sides, the left side of each of the two sliding blocks 2845 is fixedly installed with a mirror image half-round clamping plate 2846, the left end of each of the two half-round clamping plates 2846 is provided with an extension plate, and the two extension plates are both provided with front and back through locking screw holes 2847, the inner circle of each of the two locking screw holes 2847 is threadedly installed with a threaded rod 2848, and the front end of the threaded rod 2848 is fixedly installed with a Y-shaped knob 2849;

[0025] When it is necessary to connect the sputum suction tube, the disposable sputum suction hose is aligned with the top of the conical adapter 281 and clamped in, and then the Y-shaped knob 2849 is directly rotated to threadedly connect the Y-shaped knob 2849 with the locking screw holes 2847 of the extension plates of the two half-round clamping plates 2846, so that the two half-round clamping plates 2846 located outside the disposable sputum suction hose are moved close to each other, and when the half-round clamping plates 2846 are moved close to each other, the right end is slidingly retained on the sliding rod 2844 outside the limiting box 2842 to keep the stability, and finally the disposable sputum suction hose sleeved on the outer wall of the conical adapter 281 is clamped and further reinforced.

[0026] As shown in the figure, Figure 5 The outer wall of the negative pressure suction pipe 3 is sleeved with a suction hose 1 31, the other end of the suction hose 1 31 is sleeved with an air filter box 32, the right end of the air filter box 32 is sleeved with a suction hose 2 33, the top rear side of the sealing top cover 24 is fixedly connected with a suction adapter pipe 242, the other end of the suction hose 2 33 is sleeved with the outer wall of the suction adapter pipe 242, and the inner cavity of the air filter box 32 is provided with a filter cotton core 321.

[0027] Start the negative pressure machine 1, drive the eccentric wheel to rotate quickly by the motor inside the negative pressure machine 1, so that the suction hose 1 31, the air filter box 32 and the suction hose 2 33 connected with the negative pressure suction pipe 3 suck out the air in the bottle from the suction adapter pipe 242, and discharge through the self-provided exhaust hole, so that the negative pressure suction collecting bottle 22 generates negative pressure through continuous circulation, the negative pressure acts on the sputum in the respiratory tract, and the sputum is sucked into the sputum suction tube, as the sputum is sucked in, the pressure in the tube gradually rises, when reaching the preset threshold value, the sputum will be pushed into the negative pressure sputum collecting bottle 22, and at the same time, the gas sucked out by the negative pressure suction pipe 3 can be filtered by the filter cotton core 321 in the inner cavity of the air filter box 32 when passing through the air filter box 32, so as to avoid dust entering the inside of the negative pressure machine 1.

[0028] The working principle of this nursing sputum suction device will be explained in detail below.

[0029] like Figures 1-5 As shown, when connecting the suction catheter, one end of the disposable suction tube is aligned with the top of the conical connector 281 and inserted. Then, the Y-shaped knob 2849 can be rotated directly. The Y-shaped knob 2849 is threaded into the locking screw holes 2847 of the extension plates of the two semi-circular clamps 2846, thereby bringing the two semi-circular clamps 2846 located on the outside of the sleeved disposable suction tube closer together and tightening them. When the semi-circular clamps 2846 tighten and move, the right end uses the slider 2845 to slide on the outer wall of the slide rod 2844 in the slide groove 2843 of the limiting box 2842 to maintain tightening stability. Finally, the suction tube is sleeved on the outer wall of the conical connector 281. The disposable suction tubing is clamped to further reinforce the connection. After connection, the negative pressure machine 1 can be started. The motor inside the negative pressure machine 1 drives the eccentric wheel to rotate rapidly, thereby using the suction tubing 31, air filter box 32, and suction tubing 33 connected to the negative pressure suction tube 3 to draw air out of the bottle through the suction connector 242 and discharge it through the built-in exhaust port. This continuous rotation creates negative pressure in the negative pressure suction collection bottle 22. This negative pressure acts on the sputum in the respiratory tract, drawing it into the suction tube. As sputum is drawn in, the pressure inside the tube gradually increases. When a preset threshold is reached, the sputum is pushed into the negative pressure suction collection bottle 22. When the gas extracted by the negative pressure suction tube 3 passes through the air filter box 32, it can be filtered by the filter cotton core 321 inside the air filter box 32 to prevent dust from entering the negative pressure machine 1. When it is necessary to clean and disinfect the negative pressure suction collection bottle 22, first disconnect the suction hose 33 at the top of the suction connector 242, then disconnect the fixed disposable suction hose, directly remove the negative pressure suction collection bottle 22 from the placement ring 21, then use the lifting handle 27 to pull up the sealing top cover 24, and rotate the conical connector 281 to use the threaded connection between the external threaded tube 282 and the threaded hole 241 to remove the entire conical connector 281, thereby allowing for the cleaning and disinfection of the disposable suction bottle. The conical connector 281 of the sputum tubing connection is thoroughly cleaned and disinfected. During installation, simply align the external threaded tube 282 with the threaded hole 241 and tighten it until the limiting plate 283 stops against the top of the sealing cap 24. The threaded connection improves the sealing performance. Then, use the lifting handle 27 to press the overall sealing cap 24 into the inner cavity of the negative pressure suction collection bottle 22. This allows the sealing plug 25 to improve the sealing performance after insertion by squeezing the two rubber sealing rings 26 on its outer wall against the negative pressure suction collection bottle 22. Finally, reconnect the soft suction tubing 23 to the suction connector 242 to perform negative pressure suction again.

[0030] The utility model is described in detail above, but some modifications or improvements can be made on the basis of the utility model, which is obvious to the general technical personnel in the technical field. Therefore, the modifications or improvements without departing from the utility model's ideological spirit are within the utility model's protection scope.
