The inflating device 2-2 inflates the saccule 2-1 through the inflating pipeline 2-3 and the inflating channel 2-4. The inflator 2-2 in this embodiment is preferably a medical latex pressurized balloon; the balloon 2-1 in the embodiment is a medical balloon made of polyurethane materials, and the volume of the balloon 2-1 can expand into a spherical shape when the balloon is inflated inwards.

The suction system 3 comprises a suction tube 3-1, a suction channel 3-2 formed in the wall of the cannula 1-1 and a connector 3-3. The connector 3-3 is a pipeline structure which is communicated up and down, the upper end of the connector 3-3 can be connected with a medical air suction pump or other medical appliances according to actual requirements in actual use, in the embodiment, the upper end of the connector 3-3 is connected with the medical air suction pump, and the lower end of the connecting pipe 3-3 is connected with an opening at the upper end of the suction pipe 3-1 and is communicated with the inside. The lower end opening of the suction pipe 3-1 is connected with the suction channel 3-2 and communicated with the inside. The suction tube 3-1 is equipped with the water injection pipe 4 of bypass on leaning on the upside position, and the water injection pipe 4 is equipped with the three-way valve 5 that the control pipeline switches with suction tube 3-1 junction, and two kinds of pipeline break-make modes can be realized to three-way valve 5: firstly, a bypass where a water injection pipe 4 is located is closed, and a main path where a suction pipe 3-1 is located is conducted; and secondly, the pipeline of the suction pipe 3-1 at the upper part of the three-way valve 5 is closed, and the water injection pipe 4 is communicated with the pipeline of the suction pipe 3-1 at the lower part of the three-way valve 5 through the three-way valve 5. The suction channel 3-2 is a herringbone structure, and comprises a first suction channel 3-2-1 and a second suction channel 3-2-2. The upper ends of the first suction channel 3-2-1 and the second suction channel 3-2-2 are converged and communicated into a channel, then the channel is connected with the lower end opening of the suction tube 3-1 and is internally communicated, and the lower ends of the first suction channel 3-2-1 and the second suction channel 3-2-2 are respectively provided with a first suction port 3-4-1 and a second suction port 3-4-2 which are communicated with the outside on the tube wall of the insertion tube 1-1 above the saccule 2-1. The first suction port 3-4-1 and the second suction port 3-4-2 are symmetrically arranged by taking the circle center of the radial section of the cannula 1-1 as the center. The first suction port 3-4-1 and the second suction port 3-4-2 are both oval openings with the long axis parallel to the radial section of the cannula 1-1.

The working of this embodiment is as follows:

the multifunctional trachea cannula is inserted into an operation position from a trachea of a patient (the position is automatically adjusted by medical staff according to different conditions of the patient), then the inflating device 2-2 is operated to inflate, air (generally, external air) inflated by the inflating device 2-2 sequentially passes through the inflating pipeline 2-3 and the inflating channel 2-4 and then enters the saccule 2-1, the saccule 2-1 gradually expands to be spherical in volume and then is clamped on the trachea wall of the patient to form blockage of the trachea, and therefore communication between the inside of the patient and the external air is achieved through the ventilating channel 1-2 in the cannula 1-1.

After the multifunctional tracheal cannula is used for a period of time, sputum and other body fluids can be secreted in the trachea of a patient, as the balloon 2-1 of the embodiment seals the trachea of the patient, the sputum and other body fluids can be collected on the upper side of the balloon 2-1, the three-way valve 5 is operated to form a first on-off mode, namely, the bypass where the water injection tube 4 is located is closed, the main path where the suction tube 3-1 is located is conducted, the medical suction pump connected with the connector 3-3 is started, the collected sputum is sucked into the first suction channel 3-2-1 and the second suction channel 3-2-2 through the first suction port 3-4-1 and the second suction port 3-4-2 on the two sides under the suction of the medical suction pump and then is sucked out of the body through the suction channel 3-2, the discharge of sputum is realized; the accumulated sputum is sucked through the first suction port 3-4-1 and the second suction port 3-4-2 on the two sides, and compared with the prior art, the sputum suction device has a wider suction area and a better suction effect due to a single opening.

After the suction is carried out for a certain time, the three-way valve 5 is operated to form a second on-off mode, namely, the pipeline of the suction pipe 3-1 at the upper part of the three-way valve 5 is closed, the water injection pipe 4 is communicated with the pipeline of the suction pipe 3-1 at the lower part of the three-way valve 5 through the three-way valve 5, at the moment, medical pure water is injected inwards through the water injection pipe 4 of the three-way valve 5, at the moment, a medical injector or other medical water injection equipment can be adopted for injection, the medical pure water is divided into a first suction channel 3-2-1 and a second suction channel 3-2-2 after sequentially passing through the water injection pipe 4, the three-way valve 5 and the suction channel 3-2, and finally enters the position above the saccule 2-1 through the first suction port; and finally, operating the three-way valve 5 again to form a first on-off mode, and sucking the sputum washed above the balloon 2-1 out of the body through a medical aspirator pump to realize the discharge of the sputum. Because the sputum stickness is great, often thorough inadequately during the suction, can lead to the sputum to remain, through three-way valve 5's washing function in this embodiment, reduce the stickness of long-pending phlegm, the suction is more thorough.

The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
