The disease course is relatively long, and even long-term bedridden. Sputum is easy to deposit in the lung base and cannot be coughed out. Sputum cannot be coughed out, which is easy to cause secondary bacterial infection and affect normal breathing. Therefore, the sputum suction tube for lung clearing and sputum discharging can keep the respiratory tract unobstructed.

[0003] When the lung clearing and sputum discharging device for respiratory medicine is used, a set of suction device can be composed of the sputum suction tube, the suction pump and the air outlet pipe under normal circumstances, so that the sputum suction tube can achieve the effect of sucking sputum. The sputum reaches the bottom of the sputum storage tank automatically, and the sputum storage tank can be easily taken out by detaching the detachable cover through the sputum storage tank, the connector and the detachable cover. The sputum is cleaned. When the lung clearing and sputum discharging device is discharging sputum, the sputum suction tube needs to be inserted into the respiratory tract of the patient to suck the sputum. The patient closes his mouth due to the foreign body sensation in the throat, and the tongue also moves up and down to resist the entry of the sputum suction tube.

[0039] The working principle of the above technical solution is described as follows: In use, the sputum cup 1 is installed on the side of the box 4, and the sputum suction tube 3 and the output pipe 5 are connected to the sputum cup 1. One end of the sputum suction tube 3 is connected to the expansion device 2, and one end of the output pipe 5 is connected to the negative pressure pump inside the box 4. The negative pressure pump is connected to the power supply on the box 4 to start, thereby measuring the sputum suction through the sputum cup. When suctioning sputum from the patient, the size of the expansion ring 26 is adjusted by the threaded adjusting column 21, and the threaded adjusting column 21 is fixed and limited by the adjusting ring 23, so that the expansion ring 26 can be adjusted according to the size of the patient's oral cavity, thereby clamping the two expansion mechanisms 24 on the patient's mouth to expand the patient's mouth. Then, the sputum suction tube 3 is inserted into the expansion ring 26 through the insertion port 25, and the sputum suction tube 3 is inserted into the patient's throat. During the insertion process, the tongue is pressed by the tongue pressing mechanism 22. The outer frame 226 on the tongue pressing mechanism 22 is fixedly connected to the lower end of the expansion ring 26, and is moved by the adjusting mechanism 225 in cooperation with the tongue pressing plate 227. One end of the tongue pressing plate 227 extends out of the outer frame 226 through the opening in the side of the outer frame 226. The tongue pressing plate 227 can be extended and retracted according to the length of the patient's tongue under the action of the adjusting mechanism 225. The adjusting mechanism 225 is parallelly installed on the swinging guide disc 223, and the movable pullers 221 on both sides of the swinging guide disc 223 are connected between the adjusting mechanism 225 and the positioning seat 224. When the adjusting mechanism 225 drives the tongue pressing plate 227 to adjust, the swinging guide disc 223 at the lower end of the adjusting mechanism 225 and the positioning seat 224 adopt the activity principle of a tilting figure to adjust. The swinging guide disc 223 can support the adjusting mechanism 225 to prevent the adjusting mechanism 225 and the tongue pressing plate 227 from separating during the movement. The multiple sections of the guide rods on the movable pullers 221 on both sides of the positioning seat 224 can be extended and retracted with the movement of the adjusting mechanism 225. This not only effectively supports the tongue pressing plate 227, but also adjusts the angle of the tongue pressing plate 227. The extension section 222 connected to the upper end of the adjusting mechanism 225 is simultaneously pulled and stretched during the movement of the adjusting mechanism 225, effectively ensuring the stability of the reciprocating movement of the adjusting mechanism 225. The adjusting mechanism 225 can adjust the position of the tongue pressing plate 227 according to the position of the patient's tongue, so that the tongue pressing plate 227 can directly contact the patient's tongue. The fixed block 2253 on the adjusting mechanism 225 is embedded in the outer frame 226. The angle swing disc 2252 and the movable block 2254 on the fixed block 2253 are connected.

The angle swing disc 2252 is provided with multiple clamping pieces, so that the lower end of the movable block 2254 is buckled with the clamping pieces on the angle swing disc 2252 after the movement adjustment, effectively moving the position of the tongue pressing plate 227 to press against the patient's tongue.The movable block 2254 is fixedly connected with the joint block 2554 on the moving assembly 2255, so that the slide 2552 and the movable block 2254 are connected together, the adapter block 2556 is arranged on the right side of the slide 2552, and the adapter block 2556 is fixedly connected with the tongue depressor 227 on one side. The adapter block 2556 can drive the tongue depressor 227 to move back and forth on the guide rail 2555 in the slide 2552 according to the length of the patient's tongue. The guide rail 2555 is provided with a plurality of notches, and the notches are connected with the protrusions 2553. The two form a wave structure, so that when the adapter block 2556 moves on the guide rail 2555, the clamping ball 2551 on the upper end of the adapter block 2556 is matched and clamped with the notch on the guide rail 2555, and the protrusions 2553 between them can play a role in auxiliary guiding, so that the adapter block 2556 can be stably moved on the guide rail 2555. When the adapter block 2556 drives the tongue depressor 227 to adjust to a certain position, the clamping ball 2551 on the adapter block 2556 is matched and connected with the notch on the guide rail 2555, and the protrusions 2553 at both ends are lifted, thereby wrapping the clamping ball 2551, effectively limiting the adapter block 2556 at the adjusted position, so that the adjusted tongue depressor 227 can match the length of the patient's tongue, effectively avoiding that the tongue depressor 227 is too short to stably press the tongue, or too long to extend into the patient's throat. Through the cooperation of the tongue depressor 227 and the cavity expanding mechanism 24, the mouth and tongue of the patient are supported and pressed, effectively avoiding that the patient closes the mouth or the tongue also moves up and down to resist the entry of the sputum suction tube 3. The medical staff can stably and accurately extend the sputum suction tube 3 through the patient's throat into the respiratory tract, effectively avoiding that the patient's throat is scratched red due to the movement of the tongue.
