It also includes a drug delivery tube 3 for delivering liquid medicine, one end of the drug delivery tube 3 is connected to a syringe 7, and the other end thereof is connected to a nozzle 4. The end of the drug delivery tube 3 on which the nozzle 4 is installed can extend from the inside of the oral dilator 1 into the patient's oral cavity, and continue to extend from the patient's oral cavity into the patient's respiratory tract. The syringe 7 is used to inject liquid medicine into the drug delivery tube 3. The side wall of the nozzle 4 is provided with a plurality of spray holes 5 that are connected inside and outside, and the liquid medicine can be sprayed to the respiratory tract disease site through each spray hole 5.

The working principle and technical effect of this embodiment are as follows: when directly administering medicine to the patient's respiratory tract, such as spraying medicine to the throat of the patient's upper respiratory tract, the medical staff instructs the patient to open his mouth wide, and installs the oral dilator 1 in the patient's mouth, and uses the oral dilator 1 to keep the patient's mouth open. At the same time, the tongue depressor 2 is installed in the patient's mouth with the oral dilator 1, and the tongue depressor 2 presses the patient's tongue to prevent the patient's tongue from arching or wriggling. The medical staff uses the syringe 7 to inhale the medicine solution, and connects the syringe 7 to the drug administration tube 3, and extends one end of the drug administration tube 3 with the nozzle 4 installed from the inside of the oral dilator 1 into the patient's mouth, and The nozzle 4 is inserted into the diseased part of the throat of the patient through the patient's mouth, and the medical staff injects the medicine into the drug delivery tube 3 with the syringe 7. The medicine flows into the drug delivery tube 3 and the nozzle 4, and is sprayed to the diseased part of the throat of the patient through each medicine spraying hole 5, so as to directly apply the medicine to the diseased part of the throat of the patient; after the medicine application is completed, the drug delivery tube 3 is taken out and the oral dilator 1 is disassembled; the drug delivery device can use the tongue depressor 2 to press the patient's tongue, which can prevent the patient's tongue from arching up and obstructing the medical staff's sight during intubation or drug delivery, and can prevent the patient's tongue from moving and affecting the intubation or drug delivery of the drug delivery tube, thereby reducing the phenomenon of inadequate drug delivery and improving the drug delivery efficiency.
