[0026] The driving assembly 22 includes a rectangular limiting sleeve 221. The inner wall of the rectangular limiting sleeve 221 is slidably connected to the outer wall of the suction tube 137, and the outer wall of the rectangular limiting sleeve 221 is slidably connected to the inner wall of the rectangular limiting groove 212. Connecting plates 1 and 222 are fixedly connected to the upper and lower sides of the front side of the rectangular limiting sleeve 221. The outer walls of the connecting plates 1 and 222 are slidably connected to the inner walls of the connecting through hole 216 and the mounting groove 1 and 218. A connecting plate 223 is hinged to the end of the connecting plate 1 and 222 away from the rectangular limiting sleeve 221, and a connecting plate 3 and 224 are hinged to the end of the connecting plate 223 away from the connecting plate 1 and 222. Guide plates 225 are fixedly connected to both the left and right sides of the connecting plate 224. The outer wall of the guide plate 225 is slidably connected to the inner wall of the guide groove 219. An insert block 226 is fixedly connected to the front side of the connecting plate 224. The outer wall of the insert block 226 is inserted into the inner wall of the slot 113. Fixing rods 227 are fixedly connected to both the left and right sides of the front side of the rectangular limiting sleeve 221. The outer wall of the fixing rod 227 is slidably inserted into the inner wall of the mounting through hole 217. A spring 228 is sleeved on the rear side of the outer wall of the fixing rod 227. The front side of the rectangular limiting sleeve 221 can abut against the pressing end of the pressing valve 215.

[0027] The extension component 23 includes trapezoidal clamps 231. The outer walls of the two trapezoidal clamps 231 that are far apart from each other are slidably connected to the outer walls of the two sealing clamps 112 that are close to each other. The inner walls of the trapezoidal clamps 231 are fixedly connected to two arc-shaped drug outlet tubes 232. The outer walls of the arc-shaped drug outlet tubes 232 are slidably inserted into the inner walls of the arc-shaped drug outlet holes 2101. The middle parts of the sides of the two trapezoidal clamps 231 that are close to each other are connected to the limiting sleeve 131 and the drug outlet tube 13. The outer wall of the rear end of the trapezoidal clamp 231 is in contact with the extension block 233 fixedly connected to both the left and right sides of the rear side of the trapezoidal clamp 231. The outer wall of the trapezoidal clamp 231 is slidably connected to the interior of the mounting groove 210. The rear side of the extension block 233 is fixedly connected to the sliding sleeve 234. The inner wall of the sliding sleeve 234 is slidably connected to the sliding rod 235. The rear side of the outer wall of the sliding rod 235 is fitted with a spring 3 236. The front and rear ends of the sliding rod 235 are fixedly connected to the inner wall of the mounting groove 210.

[0028] In use, the rear end of the suction tube 137 is first inserted into the circular through hole 213, the fixing cylinder 214, and the rectangular limiting sleeve 221. Then, the front end of the suction tube 137 is inserted into the inside of the dispensing tube 132. Next, the drug storage structure 2 is pushed towards the fixing structure 1. When the front side of the drug storage shell 211 is in contact with the outer wall of the rear side of the mounting shell 111, the L-shaped block 127 is inserted into the inside of the L-shaped groove 2102. At the same time, the sealing clamp 112 will squeeze the trapezoidal clamp 231, causing the trapezoidal clamp 231 to slide inside the mounting groove 210, thereby driving the arc-shaped dispensing tube 232 to move along the inner wall of the arc-shaped dispensing hole 2101. The sliding mechanism moves via the trapezoidal clamp 231, causing the extension block 233 to slide the second sliding sleeve 234 against the outer wall of the second sliding rod 235, and compressing the third spring 236. When the drive fixing assembly 12 fixes the suction tube 137, the movement of the limiting plate 126 causes the L-shaped block 127 to slide against the inner wall of the L-shaped groove 2102, thereby locking the medicine storage shell 211, and then installing the rear end of the suction tube 137 onto the suction device 3. When sputum in the patient's throat blocks the airway and affects breathing, the suction device 3 can be used directly to quickly remove the sputum from the airway through the suction tube 137, ensuring the patient's breathing is unobstructed. By pre-filling the medicine solution into the storage shell 211 through the inlet 2103, when medication is needed, the rectangular limiting sleeve 221 is pressed and slides forward on the inner wall of the rectangular limiting groove 212. During the movement of the rectangular limiting sleeve 221, the connecting plate 222 and the fixing rod 227 move simultaneously. The fixing rod 227 slides on the inner wall of the mounting through hole 217, thereby compressing the spring 228. The movement of the connecting plate 222 pushes the connecting plate 223, causing the connecting plate 224 to slide on the inner wall of the mounting groove 218, and causing the guide plate 225 to slide on the inner wall of the guide groove 219, thereby causing the two connecting plates 224 to move away from each other. The movement of the connecting plate 224 causes the insert block 226 to move the sealing clamp 112 outward, and the sliding sleeve 114... Synchronously sliding on the outer wall of the slide bar 115, it compresses the spring 116. After the two sealing clamps 112 move away from each other, they release the restriction on the two trapezoidal clamps 231. Then, under the action of the spring 236, the trapezoidal clamps 231 pop forward and come into contact with the front end of the dispensing tube 132. At this time, the arc-shaped dispensing tube 232 will be connected to the dispensing hole 133. By continuously pressing the rectangular limiting sleeve 221, the rectangular limiting sleeve 221 will apply pressure to the pressing end of the pressing valve 215. After the pressing valve 215 is squeezed, the liquid medicine inside the storage shell 211 is pressurized and sent out. The liquid medicine enters the arc-shaped dispensing tube 232 through the arc-shaped dispensing hole 2101, and then is evenly delivered to the front end of the dispensing tube 132 through the dispensing hole 133. It is then sprayed onto the patient's throat through the dispensing hole 133 on the outer wall of the dispensing tube 132, completing the precise medication delivery. After releasing the pressure on the rectangular limiting sleeve 221, the second spring 228 pushes the rectangular limiting sleeve 221 to move backward and reset. The third connecting plate 224 retracts simultaneously, the insert block 226 releases the pressure on the sealing clamp 112, the first spring 116 pushes the sealing clamp 112 to reset, and the trapezoidal clamp 231 is retracted by being squeezed again. The arc-shaped drug outlet tube 232 and the drug outlet hole 133 are separated by the sealing clamp 112 to avoid unnecessary leakage of the drug solution. The entire operation does not require repeated insertion and removal of the suction tube. The drug can be administered directly and quickly after suctioning, reducing the stimulation of the patient's airway. The operation is convenient and the structure is stable.
