Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example: Reference Figure 1-12An artificial airway suction tube is shown, comprising a silent treatment cabinet 1, the inner wall of the silent treatment cabinet 1 is slidably connected to a first drawer 2, the inner bottom wall of the first drawer 2 is fixedly connected to a buffer mechanism 3, a medical sputum suction machine 16 is arranged on the upper side of the buffer mechanism 3, a second drawer 4 is slidably connected to the inner wall of the silent treatment cabinet 1, a drying mechanism 5 is fixedly connected to the inner bottom wall of the second drawer 4, a third drawer 6 is slidably connected to the inner wall of the silent treatment cabinet 1, a sterile packaging bag 7 is installed inside the third drawer 6, a sputum suction assembly is arranged inside the sterile packaging bag 7, an airflow filter 8 is fixedly connected to the upper side of the silent treatment cabinet 1, a medical tray 9 is arranged on the upper side of the silent treatment cabinet 1, a trial suction cup 10 is arranged on the inner bottom wall of the medical tray 9, and a flushing cup 11 is arranged on the inner bottom wall of the medical tray 9.

The medical suction machine 16 has both suction and oxygen supply functions. Medical staff can switch functions through the air flow filter 8. There are already mature equipment on the market, and no further elaboration is made here. The air flow filter 8 can humidify and filter the airflow to reduce the patient's discomfort. The suction component is the commonly used sterile suction tube. The operation of the drying mechanism 5 can keep the inside of the third drawer 6 dry, ensuring that the suction component in the sterile packaging bag 7 can be preserved for a long time.

The inner walls of the two rotating holes are rotatably connected to the rotating shafts 511, and the front ends of the two rotating shafts 511 are rotatably connected to the front inner wall of the drying box 501, and the rear ends of the two rotating shafts 511 are rotatably connected to the rear inner wall of the drying box 501.

[0039] The shelf is provided to provide a stable support for the installation of the rotating shaft 511 , and the shelf divides the interior of the drying box 501 into two chambers, one with a desiccant and the other without a desiccant.

[0040] In this embodiment, the surfaces of the two rotating shafts 511 are fixedly connected with transmission gears 512, the rear sides of the two transmission gears 512 are rotationally connected to the front side of the partition 514, the two transmission gears 512 are meshed with each other, and the surfaces of the two rotating shafts 511 are fixedly connected with spiral push blades 513.

[0042] As a preferred implementation scheme in this embodiment, the buffer mechanism 3 includes a buffer base 301 fixedly connected to the inner bottom wall of the first drawer 2, and a damping shock absorber 302 is fixedly connected to the upper side of the buffer base 301. The number of the damping shock absorbers 302 is two, and the two damping shock absorbers 302 are symmetrically arranged on the upper side of the buffer base 301 with the horizontal center line of the upper side of the buffer base 301 as the symmetry axis. The upper sides of the two damping shock absorbers 302 are fixedly connected to the same support plate 303, and the upper side of the support plate 303 is fixedly connected to the lower side of the medical suction machine 16. A buffer mounting groove 304 is opened on the upper side of the buffer base 301. The number of the buffer mounting grooves 304 is two, and the two buffer mounting grooves 304 are symmetrically arranged on the upper side of the buffer base 301 with the vertical center line of the upper side of the buffer base 301 as the symmetry axis, and the inner bottom walls of the two buffer mounting grooves 304 are both slidably connected with buffer components.

[0043] The damping shock absorber 302 is provided to absorb vibration. The damping shock absorber 302 is a common shock absorbing device and provides stable support for the support plate 303 .

[0044] In this embodiment, the buffer assembly includes two buffer sliders 306 that are slidably connected to the inner bottom wall of the buffer mounting groove 304, and the front sides of the two buffer sliders 306 are provided with sliding holes. The front and rear inner walls of the buffer mounting groove 304 are fixedly connected with the same smooth rod 305, and the surface of the smooth rod 305 is slidably connected to the inner wall of the sliding hole. The opposite surfaces of the two buffer sliders 306 are fixedly connected with the same damping buffer spring 307, and the upper sides of the two buffer sliders 306 are rotatably connected with a buffer connecting rod 308, and the end of the buffer connecting rod 308 away from the buffer slider 306 is rotatably connected to the lower side of the support plate 303.

[0045] By setting the damping buffer spring 307, the dynamic potential energy brought by inertia is converted into elastic potential energy, so as to avoid the medical suction machine 16 from colliding with the silent treatment cabinet 1 under the action of inertia. The smooth rod 305 can prevent the buffer slider 306 from slipping out of the buffer mounting groove 304.

[0046] The working principle of the present invention is: an artificial airway suction tube. When using it, the user first confirms the patient's identity information and physical condition according to the prescribed medical care process, and then lets the patient breathe oxygen for five minutes. During this period, the third drawer 6 is opened to take out a pack of sterile packaging bags 7, and the suction component is taken out to connect the medical suction machine 16. The appropriate negative pressure is set, and the head suction tube 14 is inserted into the patient's artificial trachea to start the suction operation. During the suction, the noise generated by the operation of the medical suction machine 16 is isolated and absorbed by the silent treatment cabinet 1, and the noise generated by the operation of the medical suction machine 16 is The vibration is absorbed by the damping shock absorber 302, and under the action of inertia, the support plate 303 starts to move, and the movement of the support plate 303 drives the buffer connecting rod 308 to move, and the two buffer sliders 306 move away from each other. At this time, the damping buffer spring 307 is stretched, and the dynamic potential energy of the buffer slider 306 is converted into its own elastic potential energy, until the buffer slider 306 slows down and finally returns to its original position under the action of the damping buffer rod slider, so as to avoid the medical sputum suction machine 16 from jumping under the action of inertia and colliding with the silent treatment cabinet 1, To prevent the medical sputum suction machine 16 from malfunctioning under collision and ensure the normal use of the medical sputum suction machine 16, the southern region of my country enters the plum rain period in June and July, and the air humidity is high, which is not conducive to the preservation of the sterile packaging bag 7 in the second drawer 4. At this time, the air pump 502 is started, and the air pump 502 operates to extract the air in the second drawer 4 through the air inlet pipe 503, blow it to the impeller 510 through the transmission pipe 504, and drive the impeller 510 to rotate, and then inject it into the drying box 501 through the air delivery pipe 509, and the water vapor in the air flow is absorbed by the desiccant in the drying box 501, and finally through the air outlet The tube 515 returns to the second drawer 4 to ensure that the second drawer 4 remains dry, which is convenient for the user to store the sputum suction component. The rotation of the impeller 510 drives the installation shaft to rotate, and the rotation of the installation shaft drives the rotation shaft 511 on the right to rotate. With the cooperation of the two transmission gears 512, the two rotation shafts 511 rotate at the same time, thereby mobilizing the spiral push blades 513 to move. The movement of the spiral push blades 513 stirs the desiccant to move, thereby increasing the contact area between the airflow and the desiccant, ensuring the water absorption efficiency of the desiccant, and at the same time preventing the desiccant from agglomerating after absorbing water, thereby ensuring the utilization efficiency of the desiccant.

[0047] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
