[0060] In this embodiment: A sputum suction tank 48 is arranged at one end of the sputum suction box 41. An access base 49 for pipe connection is arranged at one end of the sputum suction tank 48.

[0061] The sputum suction can 48 adopted realizes the collection of the patient's sputum.

[0062] During specific use, step one: Ensure that the tracheostomy plate 11 is properly attached to the tracheotomy tube.

[0063] At this time, the user binds the tracheotomy tube of the user to the area of the binding strap 13 according to the hinge shaft 12, and the binding strap 13 is fixed to the patient's neck.

[0064] Utilize the hinge shaft 12 to change the agitation and flipping of the two side binding straps 13, then hang the cleaning saline bag 295 and place it on the access buckle 296. After dripping is achieved by introducing one end of the cleaning saline bag 295 into one end of the cleaning dropper 294, it is introduced into the area of the coordination seat 292 along one end of the infusion tube 293 for export.

[0065] At this time, the user extends one end of the hinge sleeve 291 to one end of the sleeve 29 and introduces it into the position of the regulating valve tube 27 to achieve introduction. Additionally, fine-tuning is performed to improve the cleaning efficiency. At this time, the user pushes the pipe fitting of the access sleeve 26 into one end of the sputum suction valve 25 to achieve introduction into the pipe body. Further export is achieved according to the valve body of the sputum suction valve 25. Finally, it is introduced into one end of the connection nut 23 along one end of the arc-shaped sleeve 24 to introduce the liquid into one end of the connection nut 23 and the three-way pipeline 21 to achieve shunt and clean the sputum in the patient's airway after connecting to the patient's tracheotomy tube. The guiding replacement is achieved by using one end of the coordination seat 292.

[0066] After achieving guiding and restricting, the state is achieved at one end of the coordination seat 292. During this process, the valve size is adjusted in the area of the infusion tube 293 to allow more water to flow in.

[0067] Step two: Collection of the sputum recovery liquid during the aspiration and flushing stage.

[0068] At this time, in order to prevent the problem of backflow of the flushing and absorption liquid, the access sleeve 26 and the regulating valve tube 27 on the surface are combined, so as to avoid the liquid being accidentally extracted by the suction structure after flushing.

[0069] Based on the fastening nut 51 connected to the side wall of the corresponding flushing pipeline 22, after the threaded connection of the nut, the liquid mixture injected into the patient's incision site is drawn out by using the connecting sleeve 52 in combination with the area of the collection bag 53 and the lower end of the collection bag 53. Without affecting the oxygen supply to the patient, under the linkage state of pressing one end of the connecting sleeve 52 in combination with the transducer button seat 57 and then connecting to the negative pressure air intake hole 58, the sputum and a large amount of water used for cleaning are inhaled into the outer collection bag 53 in advance. After discharging through the area of the suction tube 591 according to the negative pressure connecting tube 59 and the suction tube 591, it is connected to the area of the sleeve 42 along the position of the suction tube 591. Then, due to the telescopic movement of the cylinder body of the specific pneumatic cylinder 46, a negative pressure suction force is generated and reaches the inside of the sputum suction tank 48. According to the corresponding suction tube 591, during this process, by using the pipe connection state of the corresponding access nut 56, the connection state of the corresponding transducer button seat 57 is directly connected to the contact of the suction tube 591, thus realizing the guidance of the liquid under negative pressure suction. The liquid is then centrally drawn and transferred from one end of the corresponding suction tube 591 to the position of the access base 49, transferred to the area of the sputum suction tank 48 according to the area of the access base 49, and finally the liquid is drawn out based on the area of the corresponding pneumatic cylinder 46 and transferred based on the area of the sleeve 42;

[0070] Step Three: Oxygen Delivery;

[0071] During this stage, oxygen is delivered and supplied by using the ventilator connection base 31 and one end of the rear ventilator connection tube 32. To avoid sputum mixing into the oxygen tube, during the flushing process, the liquid stop delivery needs to be completed by using the linkage toggle block 28. The suction pressure can be discharged from the position of the fastening nut 51, and finally discharged through contact with the upper connecting sleeve 52 and the area of the collection bag 53. The access nut 56 and the corresponding transducer button seat 57 are used as the transfer guide for sputum waste to the rear suction tube 591 for diversion;

[0072] In addition, during the flushing stage, the oxygen three-way valve after wetting is willing not to delay the delivery. The oxygen is introduced into one end of the access sleeve 26 through the area of the ventilator connection tube 32 and then enters the sputum suction valve 25 and the incision position.

[0073] In addition, the generated oxygen is produced by the control cabinet 38, then introduced through the area of the oxygen discharge port 37, and transferred along the direction of the oxygen connection tube 35 to the position of the connection valve head 34 to achieve oxygen replacement.
